The experience of conducting field research and wri~jting~

a doctoral dissertation has no equal. The opportunity and

privilege of living on the frontier of northern Brazil has

been one that I shall never forget. To the warm, friendly

people of Brazil I express my heartfelt thanks.

I owe a tremendous debt of gratitude to many individuals

in many places. The leadership, guidance and encouragement

offer-ed by Professor Ralymond E. Crist, Chairman of m" Phi.D.

Committee, is impossible to record with proper thanks. Wlith-

out his efforts and enthusiasm this study. would not hav.e seen

the light of day. Profound appreciation is therefore grate-

fully acknowledged.

To the members of my Committee, Dr. David L. Niddrie,

Dr. W. W. MczPherson, and Dr. Hugh L. Popenoe, I express my

appreciation for their help and encouragement, each in his

own constructive way. I thank Dr. E. E. Hegen who originally

suggested Roraima as a possible study area. The teaching of

the Portuguese language and the genuine concern shown by Pro-

fessor Alfred Hower and Professor Richard Preto-Rodas are

sincerely appreciated.

From my experience in Brazil, there is an endless list

of people to whom I would like to express my gratitude for

their friendship, help and interest in the study. I thank

His Excellency, Colonel Helio Campos, Governor of the Federal

Territory of Roraima, for permission to work in the territory,

near to the sensitive boundaries with Guyana and Venezuela.

Ilmo- Sr. Sebastiao da Silva, Mlinister of Agriculture, and

Captain Carlos Augusto de Goes e Silva, Director, Department

of Production, Lands-, and Colonization, were most helpful in

providing me with information from their files. Sr. Julio

Augusto M. Martins all but adopted my family and me. His aid

and personal friendship are of an unmeasurable magnitude. My

residence in Boa Vista was made most pleasant by its citizens,

especially Amazonas Brasil, Luis Av/elino, and Esdras Av/elino

Leit o. Of course, the fazendeiros of Roraima made it all


A special note of thanks goes to Dr. Saul Benchimol, in

Mlanaus, for his invaluable efforts to initiate my work in


My family and I express our appreciation to Dr. and Mrs.

Jerry Williams who sheltered and guided us through what would

have been a very trying experience of adjustment to life in

M~anaus .

The study w~as financed by the Center of Tropical


Agriculture, Institute of Food and Agricultural Sciences,

Uni'.ersity of Florida, but any errors or misinterpretations

in thle dissertation are the responsibility of the author.

Finally, t~o miy w~ife, Dorothea, and my~ children, Niandy,

David, and ialrci, I express my~ sincere appreciation and

gratitue.1e for their perseverance and understanding during

many long day~s of my' absence from home and family.


This study was undertaken primarily to determine the

present and future possibilities of improving the quality and

increasing the quantity of beef cattle in Roraima for the

supply of urban consumers in Mlanaus. Roraima is truly one

of the "last frontiers" and precious little information has

been researched and written about this remote part of the

world. Therefore, a secondary purpose of the study was to

make basic information more available to those whose in-

terests lie ini the study of frontier areas.

Those who reside on the sav~annas of the Alto Rio Branco

and in the cities of Boa Vista and Mlanaus certainly are more

aware of their economic situations than this study ma imply.

As a foreigner, and especially as a North American, the

author found It extremely difficult to instill confidence in

the people, to convince them that he had no personal ambition

to purchase land and exploit the existing cattle interests

in Roraima. Just prior to the author's field investigation,

two North Americans had been ordered to leave the Territory

following a series of charges pertaining to business abuses.

As a result, people were very hesitant to volunteer

information on almost a7ny topic. At the other extreme, there

w~ere those individuals whi~o wanited to jnimpress upon their in-

quisitive visitor thiat their ranches were among the most

modern and efficient ji n Dazjl. Information and data given

by~ these people bore abisolut~elyr no resemblance to that which

the author observed.

All translations from Portuguese to English have been

made by the author and he maintains sole responsibility for

them. Since the terms whic-ih appear in the Glossar will be

used so often in this dissertation, they will not be

italicized after their initial use.

M~ost of mankind now? lives in a single w4orld system, and

because most of thle world's people, including Brazil's, have

found the Mletric System more practicable than alternative

measurement systems, the author has purposely been inconsis-

tent in stating units of measurement. As a gesture of respect

for the Brazilians, most of the units of measurement are

stated in the Metric System w~ith the United States Syrstem

stated in parentheses where immediate comparison is deemed


May this effort stimulate others to devote th-eir skills,

time, and effort to the problems and possibilities of pro-

ducing beef in a savanna environment and to this little known

part of the world.

Thomas Fisk Kelsey

June, 1972

Chairman: Professor Rayrmond E. Crist
Major Department: Geography

Brazil is a nation currently undergoing rapid change.

While population growth continues, more and more people are

moving from rural areas to urban centers. Almost unique among

the developing nations is the fact that Brazil's economy is

moving even faster than the rapid population changes and the

urban consumers are gaining real purchasing power on a grand


There are, however, certain regions of Brazil which have

some very real supply problems in the face of promising eco-

nomic grow~th. Mlanaus, the booming urban center of Western

Amaz~nia, experiences annual critical shortages of beef, the

most desirable source of animal protein in the diets of its

people. As a greater share of Manaus' population achieves a

suitable income, the demand for beef, a more expensive item

than the traditional high-caloric food staples, increases to

true crisis proportions.


Ly'ing some 400 miles to the north, the savannas of

Roraima hav.e produced beef on an extensive grazing basis for

nearly twso centuries, yet little material progress in pro-

ductiv~ity' has been shown since the inception of ranching

there. The ranches of Roraima are completely isolated from

major markets, save for two months out of th~e y~ear, when

cattle can be sent by river barge to Mlanaus. An al~l-weather

road will soon bring this savanna area out of isolation and

offer an opportunity for the ranchers to supply Manaus during

its critical periods of shortage.

It is the purpose of this dissertation to investigate

the supply~ pattern of beef to Manaus and to determine the

probable impacts of the road on the beef cattle industry of

the sav~annas of Roraima. An attempt will be made to demon-

strate the present degree of inaccessibility to and from

Roraima, to trace the historical revolution of ranching in

that area, determine the nature and extent of production and

marketing problems, and assess the Importance of the new road

as a possible key to alleviating the beef shortage in Mlanaus.

The ranchers in Roraima welcome the road as an avenue of

improved access to material inputs required to improve the

quality of their cattle and the performance -of their produc-

tivity, but fear that the road will lead to the creation of a

cattle complex closer to Mlanaus, thus pre-empting their


present position with respect to that market. They vliew the

negat~ive turn of events which have occurred on Mlarajd Islan~d

as a result of the completion of the Bolem-Br;asilia road as

an omen of their future and look to distant foreign markets

as their salvation. Given the magnitude of th~e problem of

overcoming foot-and-mouth disease and the growing demand for

beef in M~anaus, and viewing the situation in light of the

economic principles of opportunityy cost and the law: of com-

parative disadvantage, it appears that ranching in the

savan~nas of Roraima w~ill benefit greatlyl by thec new land

surface connection to klanaus. The ranchers w~ill havle greater

access to material supplies at less cost and will be able~ to

reach the Manaus market w~ith their cattle on a 12-month basis.




Typical of some of the other larger: nations of Latin

America, Brazil is characterized by a relative abundance of

land, and w~hen view~edd in the long-run, still enjoys a situa-

tion of underpopulation rather than ov.erpopulation. In pro-

duction, area and population, Brazil is the largest country~

in Latin Amlerica.. The nation has over 93 million people,

occupying a mainly tropical area larger than the 48 contiguous

United States. Differing from most of the underdeveloped

world, Brazil does not y~et face the Malthusian dilemma of

serious population pressure on the food supply.

This is not to say~ that Brazil does not havre a population

problem of enormous proportions. Perhaps the greatest tempta-

tion to lapse into a state of complacency~, surely a dangerous

attitude in this world of many problems, is in maintaining

the general belief that, given so much empty space, the nation

need not be concerned w~ith a high rate of population grow~th.

In this belief, Brazilians too easily~ forget that much of

this space is not yet physically productive (given present

available technical knowledge) or, ev.en if it is, it is

geographically too remote for years to come. M~ore important,

however, manyl Brazilians hal.e completely ignored the fact

that, in its economic effect, population growth places pres-

sure on the quality of the human resource as well as its

d is tribute ion Thus, even if one accepts the Iviewl that Bra-

zil's long-run optimum population might be 200 or even 300

million, the alacrityl with which they reach this size, i.e.,

the annual rate of growth, is a matter of urgent importance.

If the annual rate of natural increase continues at the

present level of 2.7 per cent, Brazil certainly wlill find it

almost impossible to ameliorate the population problem. At

such a rate of growth, it would appear that Brazil cannot

possibly allocate the massive resources required to expand

and improve its infrastructure--schools, public utilities,

public agricultural services, highways and communications,

and the like--and industrialize at the rate needed if it is

to absorb into economically worthwhile non-agricultural em-

ploy~ment a rapidly growing surplus of underemployed rural

people or unemployed urban dwellers. The agricultural sector

will suffer greatly as well. W4ith rural labor being kept

cheap and ignorant by high rates of population growth, the

modernization of agricultural techniques will seldom be

economically sound and will increase social problems b; dis-

placing labor by mechanization. Even at a much lower rate of

net population gr-owthh (for examplee 1.5 per cent), all of these

problems would still have to be confronted, but at least

gradual progress toward their solution would be feasible.l

Ai few statements are necessary to relate the previous

statements to the empirical situation. By 1960, after more

than 400 years of development, 90 per cent of Br~azil's 70.2

million people and 93 per cent of the cropland were located

in less than half the country's area and within 300 miles of

the coast. In terms of cultivated land, Brazil at about one

acre per capital did not r-ank~ far above some of the more densely

populated countries such as India and Pakistan.2 Despite con-

siderable progress since 1945, Brazil remains a dual economy

in two respects. On a geographical basis the nation is viewed

as the developed South and the under-developed Northeast and

Amazon regions. On a temporal basis, while a substantial

number of the people hav.e shared at least moderately in the

fruits of industrial and agricultural progress, the majority

remain poor. A large number of the latter earn meager incomes

in agriculture, many are underemployed in either agriculture

or in urban areas, and the remainder are unemployed. Ailong-

side this condition, the 1960 national census revealed an

illiteracy rate of 39 per cent and an average level of school-

ing of 2.4 years, emphasizing the existence of a skilled labor

shortage. Overall, annual per capital income is somewhat above

$300 U.S., but the regional distribution is very unev.en. In

the N~ortheast per capital income stands at $170,3 while in thie

state of Guan~abara (the Rio de Janeiro urban area) i~t is

almost three times thle national a.erage. This poses a serious

social and political problem and limits the effective sizce of

the consumer market.

Nonetheless, in the past two decades Brazil has made

tremendous strides. While population increased at an a\.erage

rate of sligh~tly ove~r 3 per cent in the 1950's and somewhat

under 3 per cent in the 1960's, real GN~P grew at an annual

average of 5.8 per cent in the 1949-1962 period. During the

1963-1966 period, GNP averaged only 3.25 per cent owing to

the inflation crisis during the 1962-1964 per:iod.4 NJineteen

sev.enty wa:s the third consecutive year in which Drazil

achieved close to a 9 per cent rise in real GNP. With the

population growth rate down to 2.7 per cent per annum, the

three year average GNP growth rate of 8.8 per cent translates

into an impressive annual rise of more than 6 per cent in real

per capital output.

The rapid rise of industry has greatlyr changed the

structure of the economy. Between 1949 and 1966 the combined

output of mining, manufacturing, construction and power

facilities rose about 256 per cent while agricultural pro-

duction rose by only 102 per cent.6 This has given rise to

an immense rural-urban migration and interregional migration.

About two-thirds of the population w~as rural in 1949, but the

1970 census showed that this had declined to 44 per cent.

Brazil's livestock sector as a whole lags behind other

sectors of the economy. During the last decade the prices

of livestock products hare increased fas~ter_ than the general

price level. The same has not been true for food crops. On

the demand side this reflects the strong desire of urban con-

sumers to substitute the more expensiv/e livestock products for

the cheaper cereals as their incomes rise. It also reflects

on the supply side the relatively inelastic response of

livestock production to rising prices, a co~nsequnce of the

technological backwardness and inefficiency of the livestockk

sector. Mlost assuredly, wherever urban market opportunities

exist and are not undermined by counterproductive price ceil-

ings, the producers of livestock products, even beef cattle,

are not only growing in number, but are also beginning to

follow many of the improved practices in use in more advanced


In general, however, livestock practices can still be

described in primitive or semi-colonial, chiefly characterized

by land monopoly, extensive land and livestock exploitation,

low technical standards and unsatisfactory labor relations.

Even those producers w~ho do strive for increased productive

efficiency find it difficult to achieve because they face

complex managerial problems (mnore so than crop producers) and

proceed on a purely empirical basis without reliable and

adequate technical direction. WJith an acute lack of techni-

cal and market information, improved practices are not

financially feasible, particularly since the prices of

modern agricultural inputs are rising more rapidly than

farm-product prices.

Within the category of livestock, beef is the major

source of animal protein in Brazil, accounting for nearly

three-fourths of all red meat and poultry consumed each year.

The overwhelming majority of beef is produced in the states

of Rio Grande do Sul, S~o Paulo, Mlato Grosso, Goia~s, and

Minas Gerais. The major markets lie in Brazil's South, in

the built up urban areas of Sho Paulo, Rio de Janeiro, Belo

Horizonte and P~rto Alegre. Any producing areas in the

thinly settled North are for all practical purposes excluded

from this market area by sheer distance if nothing else.

One area characterized by primitive ranching conditions

is the remotely situated Territdrio Federal de Roralma,

Brazil's northernmost political unit of state or territory.

size. Roraima contains natural grasslands to the extent of

some 16,000 square miles, which is approximately the total

combined area of Delaware and Mlaryland. It is possible that

this grassland could become the scene of modern ranching,

supplying the rapidly growing urban center of Mlanaus, Amazonas.

~IHuman population pressures pose no difficulties for this ex-

tensive activity as the population density for the entire

territory is less than 0.04 persons per square mile. Scrawny

range cattle have been grazed on these unimproved savannas

for nearly two centuries with the beef being sent to two

markets: Mlanaus (1970 population, 305,000); and Boa Vista,

the territorial capital (population estimates range between

14,000 and 30,000 with the former more likely to be repre-

sentative). Brazil's improving infrastructure, byt bringing

Roraima out of isolation, is now making it feasible to supply

beef and cattle products to areas of greater distance which

were formerly out of the market area owing to physical

barriers or prohibitive transport costs.

The objective of this study, therefore, is to examine in

detail, and in a geographical context, the present situation

of cattle-raising in Roraima and the prospects for further

development of this particular economic activity in that area.

Two major themes which the author believes are funda-

mental themes in geography will be pursued in this study.

One major theme is that of spatial arrangement and movement.

It is here that geographical elements may be characterized

as points, lines, or areas.' Furthermore, common geographical

problems may be thought of as a group of tensions created by

these geographical elements. Dimensional tension is created

between point- and area-occupying activities. For example,

on a national scale urban industrial centers may be thought

of as points, whereas agricultural activities are area-

Occupying. A dimensional tension is created by the fact

that man requires association with, and the products of, both

farmi and factory.

Another tension is that which exists between present

activities and past facilities and institutions, that is,

historical tension. In many studies past legacy may be the

single most important fact. Existing institutions and

facilities will always be lacking in suitability for the

present because man is always creating new activities which,

for greatest efficiency, necessitate new arrangements. This

tension is a fundamental geographical problem which arises

time after time, and, in fact, is a factor influencing the

beef cattle situation in Roraima Territory.

Scale, which can classify problems as local, regional,

national or world, is of primary importance. In the case of

Roraima, the spatial distribution on the surface of the

savannas cannot be ignored. This unit area dimension is a

basic concept. Mlany terms used by geographers, such as

density, rent, land value, crop yield, are compounds of the

ter~m "'unit area" with counts of other elements.

The second major theme is the relationship between man

and the env~ironment.8 In earlier times much attention of the

geographer wais focused on how the environment controls man's

behaior.Counter theories developed to this, but no example

of man's control of his environment was demonstrated by

acceptable method and, consequently, the concept is no longer

considered useful as a guide to geographic understanding.

Today the general concept accepted by geographers is

based on the notion that the physical character of the earth

means different things for different people. The significance

to mran of the physical environment is a function of the ob-

jectives, attitudes, and technical abilities of man himself.

The resource base provided by the earth takes a new meaning

with each chan e in any of the element of the human culture.

Thius, the geographer is interested in the process of inter-

action between man and the environment.

The choice of the specific tylpe of agricultural acti\.ity

at any location depends upon three prime factors. First are

site characteristics, i.e., characteristics of a particular

place such as soil, slope, micro-climate, and size and shape

of farm and field. Second are the situation characteristics,

which are defined as the elements of relati\.e position, such

as location with respect to market. The third and most

complex factor is that of technology and the socio-political

organization of the people.

Included in the socio-political organization of the

people is the polarization to subsistence societies and ex-

change (or commercial) societies. On then one hand, th~e sub-

sistence society can generally be characterized as having no

contact between groups, or at best only short range contacts.

Self-support is the rule and there is little exchange of

goods and ideas. Inherited culture prevails. Production is

labor intensive although productivity per worker is low.

Change comes about slowly~14 owing to an attitude of long-run

fatalism and the lack of an abstract image.

On the other hand, an exchange society can be described

as having long range contacts with a great exchange of

material goods and human thoughts. There is a high level of

adapted techniques. As opposed to the subsistence society's

labor intensiveness, the exchange society is capital intensive.

Labor productivity is high and rapid change is a characteris-

tic feature.

Within this framework of thinking, then, the beef

cattle industry of the Roraima savannas will be discussed in

the following chapters. But, of course, to make a valid con-

tribution to the learned world, and geography in particular,

suitable methods wouldd be selected to investigate the problem

in an orderly and scientific manner.

tThe order of discussion does not imply that one theme
is more important than the other. On the contrary, they are
of equal importance and inseparable in reality.



Outstanding researches and able formulation of bypo-

theses, like outstanding in-entions and skillful manufactur-

ing, fail to achieve notable results unless effectively

presented to a large public. It is often and truly said that

research is not complete until it is published. How!ever, as

Boring has pointed out, a badly~ written report may find no

public because it is too forbidding to be read. "What is

in the writer's mind becomes public opinion only when many

other persons read ,,and understand him." Thus, while effec-

tive presentation can never take the place of able invrestiga-

tion, it is the indispensable means of assuring full success

to any investigation. The following paragraphs will discuss

the selection of a method of inquiry and presentation.

Various levels of methodological sophistication warrants

the selection of the most appropriate method to investigate

the stated problem.2 As it is so aptly stated by Gould and


In these days of complex interregional,
nonlinear, and dynamic models one hesi-
tates to utilize simple means to approach


the problem under investigation.
However, frequently these beautiful
pr-ogranmming models havep been con-
structed in a developed en-rironment
whlere pr.ofuse and dependable data,
both for the formulation of the model
and it-s empirical test, are close at

Inl underdeveloped countries reliable data are almost non-

exsistent and the categories of available recorded material

leave muich to be desired.

The inappropriateness of using a dynamic quantitive

model to aid in the studyl of the cattle situation in Roraimra

can be seen in the followings example. Halter and Dean have

used simulation to find some improved management policies

to deal w~ith uincertain environments in which decisions were

made about buying feeders for the range, trans herring feeders

to the feedlot, and selling fat stock. To construct a model

to simulate monthly~ range conditions over a period of several

years, the authors needed a data source which would reveal

actual range conditions at the beginning of each month.

Fortunately, the United States Crop Reporting Service repre-

sents th~e desired source of information. In Brazil no such

organization and service exist. Furthermore, the data needed

to formulate decisions on direct buying for the feedlot in-

cluded expected slaughter price, final weight, days on feed,

feed cost per head per day, initial weight and an uncertainty

factor margin. Ranching and becef production in Roraima

Territoryl have yet to r~each~ the level of advancement w~hereby~

such statistics as just mnentioned are recorded or can be

conclude that:

should be raised in recommending~ simu-
lation as a general melans of analysis.

What Halter and Dean actually sho::ed was that ranch manage-

ment decisions did not, in fact, require the use of simula-

tion as an expectation model to improl.e the efficiency of

the decision to buy and sell stock.

Also, it can be safely said that the ranch managers in

the United States most likely have some degree of education

and are fully literate. In the example previously cited the

managers made almost all critical decisions of buying and

selling. To the contrary in Roraima, Ivery often the manager

is illiterate or can barely read and write and does not make

important decisions.. Instead, the absentee owner, very much

out of touch with the production aspects but more informed

about the market situation, makes the decisions. What is

missing in Roraima is the almost instantaneous flow of in-

formation .ia mass media which indeed exists in the U. S.


Gould and Sparks cry their tale of woe upon discovering

that in underdeveloped areas the quantitatil.e models hav.e

far outrun the a.ailable data. Because of this, simple models

may suffice to carry thie investigator past areas of unreliable

or incomplete data and smooth the pitfall of component

error. The authors concluded that the safest route of ap-

proach to the problem was to utilize a simple linear model.

One critical assumption they made was that the high prices

from large city markets reflect supply and demand in the near-

by' rural areas. In the case of Roraima this assumption would

not be valid, as all prices are set byl SUlaAB (Superintendincia

Nacional de Abastecimento), an autonomous government agency,

which, in fact, wreaks ha.oc on the free-w.heeling system of

supply and demand. In addition, the model would ha.e to

take into account the effect of political boundaries and

varying national economies. Thus, even a primitive." linear

model would still not operate if applied to the Roraima


Quoting the gentlemen mentioned abov.e, "In all charity,

perhaps we should remember that the Mlodel T frequently got

through and pro.ided useful service when badly potholed roads

tore sleeker models apart." Similarly, one does not send a

regiment to capture a thief wihen a few. policemen can accom-

plish the task. This author, for the purposes of this

dissertation, feels that a qualitativ.e approach is more

apropos than a quantitative approach. Owing to a lackr of

historicall; continuous records and unreliable existing data.8

the investigator turns to the process of deductive-inductive

analysis based on field evidence, observation, an~d interviews.

In the field, the investigator sought and acquired

published material, written in Portuguese an~d unavailable in

the United States, from official government offices and

agencies in Mianaus, Amnazonas and Boa Vista, Roraima. In

M~anaus, the lib-raryl of INJPA (Instituto NIacional de Pesquisas

da Amazo~nia), which is the NJational Institute for Amazonian

Research, pr~ov.ed to be a suitable beginniing point for further

library research. Other pertinent information was collected

from the Public Relations Sector, Secretary of Production,

State of Amazonas (Estado do Amazonas, Secretaria de Producao,

Setor de Relagoes Publicas). The official government sources

utilized in Boa Vista w~ere the Mlinistry of Agriculture of the

Territoryl of Roraima (M~iniste/rio da Agricultura), the office

of the Division of Production, Lands, and Colonization,

D.P.T.C. (Divis~io de Produg o, Terras, e Colonizag o), the

statistical section of Fundagio IBGE (Instituto Brasileiro

de Estatistica, Inspetoria Regional de Estatistica, Boa

Vista, Roraima), and the office of the secretary of the

mayor's administration of Boa Vista (Prefeitura Municipal de

Boa Vista, Secretaria de Administraio).

Personal contacts in the two capitals led to both the

acquisition of undistributed published material and fruitful

personal interviews. Of course, before embarking on the

actual field work in Roraima, the author paid a visit to His

Honor Francisco Zangerolame, Mayor of Boa Vista, and His

Excellency Governor Helio Campos, Governor of the Federal

Territory of Roraima, outlining his investigatory intentions.

One of the writer's original aims in gathering desired

unpublished material from ranch owners and managers was to

use a questionnaire which had been both simplified and

modified from its previous use in Costa Rica. This question-

naire is shown in Appendix A of this study. It was immediately

discovered that a gross difference in the level of advance-

ment of beef production existed between Roraima and Costa

Rica, the latter being far more advanced, and that even the

modified questionnaire was too sophisticated. Two principal

reasons for this were, first, a majority of the ranch owners

were not available for interviewing and second, most of the

ranch managers had only a minimum ability to read and write.

Furthermore, as the study will reveal, labor is so inexpensive

that machinery and fencing are still rarities in Roraima,

thus making several of the questions null and void. To com-

pensate for the loss of this useful tool the author relied

on conducting lengthy conversations with ranch owners,

managers, government officials, local businessmen, and per-

sonal friends. In each conversation a prepared set of ques-

tions was wrov.en into the exchange and hence, a ?.erbal ques-

tionnaire was, in fact, administered.

eThe following is an example illustrating the fallacies
of published data pertaining to the Roraima study. The 1968
volume of Anuario Estatistico published byl the Instituto
Brasileiro de Geografia e Estatistica (IBGE) indicates that
Roraima Territory exported 9,000 head of cattle during July
and August of 1967. This figure is official and comes from
the office of the ma yor of Boa V/ista. In reality all of the
cattle in 1967 were sent down the Rio Branco to Mlanaus. The
suppliers (marchantes) who come from Mlanaus must pay a fee
(imposto de barreira) to the mayor's office for each head of
cattle he has purchased and intends to ship to Mlanaus. In
1967 the fee was NJCrS23.OO per head. Officiallyl the suppliers
paid fees for 9,000 head of cattle which was entered in the


official records. Unofficiallyl, 12,000 cattle were purchased
and rather than pay the full fee, the suppliers bribed a
minor official with the sum of NCrS5.00 for each head of
cattle he did not record, which amounted to 3,000 head!
Th~us, the export figure is understated by 25 per cent.



Roraima, a federal territory of Brazil, with an area

of 141,009 square miles, approximately the same size as the

state of S~o Paulo or the combined areas of the Federal

Republic of Germany and the German Democratic Republic, lies

between 50 16' 19" N and 10 27' OO" S Latitude and straddles

the northern and southern hemisphere tropics.l Longitudinally,

the territory~ extends from a western extreme of 640 39' 30" W~,

eastward to an extreme of 580 58' 30" W. In terms of angu-

lar distance extremes, the linear distance from north to

south is 461 miles and from east to west it measures 392

miles. The entire region lies within the time zone four

hours less than Greenwich.

Roraima Territory is bounded internationally by Venezuela

to the north and west for a distance of some 594 miles and

shares a common border with the Republic of Guyana to the

east for 430 miles. To the southwest, south, and southeast,

Roraima is bounded by the Brazilian states of Amazonas and


That portion of the territory containing the savannas

upon which this study will focus is known as Rio Branco or

the Alto Rio Branco, and forms an area some 16,000 square

miles in extent.2 (Figure 1) The Rio Branco savannas form

a part of the Rio Branco-Rupununi region; an area covering

some 21,000 square miles. The eastern portion, covering ap-

proximately 5,000 square miles, lies within Guyana and is

commonly known as the Rupununi.

The Alto Rio Branco-Rupununi sav~anna landscape lies at

elevations ranging from approximately 300 to 1,000 feet, ris-

ing somewhat towards the margins of the watersheds. These

savannas form a gently rolling plain of rather monotonous

appearance within which isolated peaks and low ridges

occasionally rise to view above the galleria forests which

follow the streams as they meander across the landscape.3

The savanna region as a whole is enclosed by~ a series of

mountain ranges and elevated surfaces which rise 1,000 to

4,000 feet with a few isolated peaks of even higher elevation,

and are aligned in such a way as to produce a basin-like re-

lief, with the southern boundary of the basin lower and less

continuous. (Figure 1) The physiographic unit is broken

by two large drainage outlets. To the northeast, the

Rupununi River, draining the Rupununi portion of the savannas,

flows through the Essequibo system to the Atlantic Coast.

To the south, the broad alluvial plain of the Rio Branco

drains waters from the remainder of the region and passes it

on through the Rio Negro, the Rio Amazonas and ultimately

into the Atlantic Ocean. The savanna landscape occupies the

northern part of the floor of this basin-like formation.

In terms of geologic structure, the Rio Branco-Rupununi

savannas belong to the Guiana Shield, an ancient pre-Cambrian

mass that forms the nucleus of the northeastern part of South

America. Between the granitic rocks and gneisaic rocks of

the basin rim lie the alluvial lowrlands of recent fluvi~al-

lacustrine deposits which occupyl approximately half the basin

floor. Scattered areas of more elevated terrain, between

350 and 500 feet, follow along the edge of the mountain rim,

thus forming a discontinuous pattern. These areas are com-

posed of undulating gravel ridges largely of lateritic origin,

laterite plateau remnants, and long gentle sheetwash slopes.

The lowland is considered to represent part of a planation

surface provisionally dated Late Tertiary and upon this

bevelled surface the contemporary landscape has been fashioned

by Quaternary deposition and erosion.4

In modern times the main tributaries of the Amazon and

Essequibo river systems are incised into the savanna surface.

For example, at St. Ignatius Mlission, Guyana (Lat. 30 20'N,

Long. 590 50'W), the Takutu river is 10 to 15 meters (33 to

50 feet) below the general level of the surrounding savanna

surface and similar conditions prevail elsewhere. Y'e t, in

spite of this apparent, though slight, landscape rejuvena-

tion, the regional drainage system is unable to carry the

high olume of surfaces runoff during the height of the rainy

season. As a result the river levels rise at the onset of

the rains and in man: places overflow their banks. Conse-

quently, ground water drainage in the savanna is restricted

and flooding and waterlogging occur over extensive low-lying

regions. In more elevated areas, conditions are less extreme,

but even here ground water levels frequently rise close to

the surface. As the rainy season wanes, much of the surface

flood water rapi~dly disperses (by runoff and evaporation)

and is accompanied by regional lowering of levels. An

increased ground water gradient is thus established and

ground water drainage accelerates. This process is greatly

facilitated by the existence of porous sand and gravel sub-

strata, both in the low~-lying alluvial plain and in more

elevated areas to the south and east. In a few places

ground water drainage is impeded by heavy textured horizons,

and many shallow ponds and lakes may appear for several

months but during this occurrence there is no general profile

impedance and ground water levels fall fairly rapidly with

the lowering of the rivers. It is evident that the

hydrological imbalance across the watershed region contributes

to the seasonal contrast of the savanna landscape.

Before discussing the climatic characteristics of the

Alto Rio Branco, the author wishes to express a word of

caution. The Federal Territory of Roraima contains only one

official climatic data collecting station, located at the

airport in Boa Vista, the territorial capital. Observations

are made by the N~eteorological Station of the Air Route Ser-

vice, Q. G. 1st Aereal Zone, Ministry of Aeronautics (Estac o
bleteoldgia doa
Metrolgic doServico Retas Aereas, Q. G. 1 Zona Aerea, do

Ministerio da Aeroniutica). The data collected at Boa Vrista

apply only to the region of the Alto Rio Branco, that is,

the region of savannas upon which the cattle-raising takes

place, and cannot be generalized to include the region to the

north and to the south. In the extreme north lies the

mountainous region with elevations reaching a maximum of

2,875 meters (i.e., Mt. Roraima, elevation 9,219 feet), while

the station at Boa Vista is situated approximately 120 meters

(400 feet) above sea level. Also, the data cannot be

generalized to include the lower reaches of the Rio Branco

because there climatic conditions are different. In the

lower Rio Branco the vegetation is that of a dense rain

forest while the Alto Rio Branco is dominated by savannas.

However, the data obtained from the weather station at Boa

Vista are indeed pertinent to this study.

The outstanding characteristic of the Alto Rio Branco

climate is the marked seasonality of the rainfall. Tables 1

and 2 and Figure 2 reveal that at Boa Vista 78 per cent of

the mean annual total of 1,740 milimeters (69.5 inches) fell

during the four months of May~, June, July' and August, 1958-

1963. By comparison, the rainy' season in the central Amazon

Basin to the south extends a much longer period. At

Manaus (Figure 3), an annual average total of 2,128 milimeters

(85 inches), over 100 milimetem per month, fell during nine

months of the y~ear ov~er the same period of time.

Mean monthly temperatures at Boa Vista are fairly typical

of the Amazon-Cuiana region, with an average maximum of

29.loC (84.4oF) in June, during the height of the rainy sea-

son, and an average maximum of 33.3oC (91.90F) for October,

in the heart of the dry season. The mean monthly lows for

the same two months wrere 23.3oC (73.90F) and 23.6oC (74.5 F),

respectively. Thle mean diurnal range, 6.5 CO (11.7 Fo) to

9.7 Co (17.5 Fo), which is one of the most attractive features

of the savanna climate, is high for a lowland location so

close to the equator. High wind speeds in the months follow-

ing the rainy season help to dry out the inundated savannas

but at the same time greatly/ reduce the effectiveness of the

of four main categories.5 Most of the mountainous areas, at

least on their lower slopes, contain a dense corner of rain

forest. Occasionally, there are almost pure stands of pau-roxo

(purple-heart, Peltoqy~ne densiflora), a vJaluable timber tree

representing a potential resource for Roraima. The rain

forest merges into a fringing semi-deciduous forest, where

certain species lose their leaves during the dry season. A

similar type of forest occupies most of the "bush islands"

in the savanna.6 Second-growth associations tend to pre-

dominate over what are considered to be climax forms because

of the extensive practice of range grazing and repeated burn-


The savanna association is primarily of the open scrub

or woodland type. The density of the scrub varies from open

woodland formation to almost pure grassland. The dense scrub,

known as campo cerrado in the extensive savannas of Central

Brazil, is a rarity in the Alto Rio Branco. The dominant

scrub form is the fire-resistant pau-lixa, the sandpaper tree

(Curatella americana), and Trachlypogron plumosus is the

dominant grass. On iron-stone ridges and white sand the grass

grows alone, while on brown sand uplands it is joined by

other grasses such as Andropoqon anqustatus, Aristida seti-

folia, Axonopus chrqysites and Mesosetum loliiforme. The

grasses may reach over three feet in height and are found in

bunches six inches to one foot apart. On lower grounds where

there is likely to be flooding during the rainy~ season,

Trachy~pogon is supplanted by a mixed cover which includes

sedges and some low shrub forms.' In the baixas (extensive

depressions) the ground is occupied almost entirely by sedges.

Flood water may stand in these areas to a depth of several

feet for up to five months.

Although the above description and classification of

the regional vegetation is based on the excellent work. done

by Hills and others at McGill,8 other systems haver been applied

on the basis of regional terms for vegetation. The work of the

Brazilian geographer, Antinio Teixeira Guerra, exemplifies

the use of such terms.' He states that the vegetation cover

of that region is characterized by savannas that are more or
less "wooded."' The savannas of the Rio Branco represent a

series of different appearances which have regional names such

as campos agrestes, campos de baixada and campos cobertos.

The campos aqrestes is a type of vegetation having an

herbaceous cover, without shrubs and rarely with low shrubs.

The grasses are isolated or are dispersed in tufts, leaving

the soil, for the most part, uncovered. This term is also

applied to an area having a dense and continuous cover of

grass or herbaceous plants, which is not the case found in

Roraima. The campos agrestes, also called lavrados, correspond

to the true plains, being almost de.oid of trees or even


On the campos agrestes the existing grass is not pala-

table to the grazing cattle who look, instead, for the camp~os

do baixada, which corresponds to humid pasturles. Phlysiognomi-

cally the onlly feature which differentiates these areas fromn

the lal.1ado is that in the campos do baixada (or- simply

baixilr) the grass forms a continuous, is tenderer, and

contains somec buriti plam, by virtue of th~e greater hulmidity.

Camouos cobertos is the name given bl the local inhabhi-

tants to the sav~annas up~on which trees and shrubs begin to

a~pper. This grades into, w~hat is known as the cerradoes,

w.hich is defined as w:aterless scrub wastelands.

Although the classification and description of the

v.egetation gi.en Guerra falls far short of than gi.:en- bl Hills

and others of the McGill Univ.ersitl Sarvanna Research~ Project,

it is included here to showI that regional vegetational termsn

do exist in the Alto Rio Branco and that the local people do

have an awareness of the varietl of their physical environ-

ment. The author found that among the ranch hands and rural

dwellers the term most frequ~entlly used in a blanket fashion

when asked to identify grasses, trees, soils', etc., was

simply agreste.1

The soils of the Alto Rio Branco can be characterized

as being highly acidic and veary low in all nutrients and

bases. Chemical weathering of tropical soils occurs at

approximately three times the rate of weathering in middle

latitudes. This leads to very deep senile soils. The deep

weathering occurrence is particularly~ the case where the

soil surface is easily penetrable, such as on the lateritic

ridges where drainage is rapid. The excessive eluviation of

clay and organic matter reduces the water retaining capacityl

of the surface soil. The resulting dcop desiccation in the

dry season further increases: the loss of soil constituents

and thus intensifies th~e detrimental cycle. If~ the soil sur-

face becomes compacted by~ h-eavy rainfall, high insolation, and

the removal of vegetation by~ fire, then sheet :ashl, gully~ing

and severe erosion generally occur. Hiumus is rapidly decom-

posed in the tropics owing to the increased activity of the

soil bacteria in higher temperatures.

Referring to the studies of the MCGill Univ.ersity Savranna

Research Project, there are perhaps three main intergrading

groups of soils in the Roraima savannas:

a. Soils of the Flats: These are the lowland soils.
They are pale colored silts and clays and
occasionally havre a thin organic cover. In some
places they become yellow in lower horizons, and
occasionally contain red iron or black manganese
nodules. These soils are flooded regularly,. then
desiccated, and the result of the fluctuating
water table appears to be the promotion of lateri-
zat ion.

b. Gra:.elly? Soils: These occur on upland sites and
are composed of secondary laterite or "peridigon."
These contain pebbles ranging from three inches
in diameter to large pisoliths, set in a matrix
of red earth which becomes paler in the lower

c. Gra; Soils: These occur also on upland sites,
but are composed of a mixture of gray sand,
and silt or silty clay. N~assivle or primary
laterite occasionally outcrop in both these

From this brief introduction to the landscape of the

Alto Rio Branco in Roraima it is evident that a far from ideal

natural environment for human land settlement anid occupation

exists. The soils are lacking in nutr-ients andr~ L!e soil

structures leave much to be desired. I-lost of the natural

vegetationn is not palatable to grazing animals and the distri-

bution of rainfall throughout the year is ex;tremely~ unfav.orable

both to the formation of a habitable environment and to man's

activities. In order to overcome such physical disadvantages

any form of economic activity would require technical

knowledge, skills, material supplies, and large capital in-

puts. In the chapters which follow the author hias I.iewed in

the field the consequences of this relationship between man

and the physical milieu.


The Federal Territoryl of Roraima was officially
created by Law 5,812 of September 13, 1943. Prior to this
time the area was part of the state of Amazonas. Although
the territory was legally authorized In 1943, it was not
until June 20, 1944 that the territory actually came into
existence. At that time it w~as known as the Federal Territory
of Rio Branco, taking its name from the river. In mid-1963
the official name of the territory was changed from Territorio
Federal do Rio Branco to Territorio Federal de Roraima.

5The classification of vegetation is extremely compli-
cated and confusing. For the sake of clarity and understand-
ing, the author will state what he feels are the most concise,
but accurate, statements pertaining to vegetation. For those
extremely interested in more detailed information about the
vegetation of this region, consult the McGill University
Savanna Research Project, Department of Geography, McGill
University, P.O., Canada.

6The "bush island" phenomenon is very common in the Rio
Branco-Rupununi savannas. As the term implies, the formation
of forest or dense scrub appears on the savranna landscape as
an island, often circular In shape. Most likely the bush

islands are remnants of earlier forest formations which have
been greatly reduced by burning and grazing activities. In
some bush islands forest regeneration begins, but, because
of a regional lowering of the water table, it is unlik~ely cou
progress very far. The bush islands probably~ will fall prey;
to savranna fires in the future.

7jMost likely, among the sedges would be found Rynchosgors
spp., Dichromena spp., Seleria spp., and Stenophy.llus spp.
The sedges are less strongly tufted and grow more closely: to-
gether than in the grass-dominant areas. Some shrub anid

include Psidium spp., Palicourea spp., Casearea spp., Pandia:~_

the phrase mais ou menos cerrados. The term cerrada has
several meanings, but w~hen used in reference to vegetation it
means a sav~anna w~ith scattered thickets of deciduous sc-rub

11Jacques Ourique (O Va'le do Rio Branco), describing such
a landscape, expressed himself in the following manner:
"The sufficiently elevated lands, the higher and more ru~ggd
the more they advanced in the direction of our frontiers with
British Guiana and Venezuela, die out along the banks of the
Rio Branco almost always in steep river banks, in the ma-
jority. of the cases elevated several meters. In that region,
so similar to the Argentine pampas and more beautiful because
of the distant chains of mountains that interrupt the hori-
zon, the entirety of nature amasses itself so that it may
become, one day, the principal and most abundant and most
diverse granaryr of this great state.

'There, beautiful green plains which extend, beyond
sight, in gentle undulations, in serene and sad continuity,
predominate, interrupted only by one or another isolated
stand of trees or by the rare groups of elegant miritizeiro
Fiber mauritia palm] The landscape is distinguished almost
always byl clear sand-bottomed lakes, devoid of vegetation,
where the thirsty~ steer quenches his thirst in the hours of
sul t rine ss ." (Ia na u s, 1906) p. 8.

12The appearance of the term agret in R~oraima is
most interesting. The overwhelming majority of people pre-
sently in Roraima, although no precise data are aailable,
ha-e either recently immigrated from or are first generation
immigrants from the sertac of the Northeast states of Ceara,
pioui, Pernambuco, Paraiba, Alagoas and rMaranh o. It is in
this region of the NJortheast that the true agreste exists.
E'.en though some sav.anna areas in Ror-aima .aguely resemble
the agreste of the NJortheast, the species of vegetation,
soils, and climatic conditions of the former differ from the
latter. What has happened then is that the uneducated people
coming from the ru~ra~l Northeast. have' spread7C the term aqreste,
but the true meaning of the term, at least in the case of
Roraima, has been abandoned.

13Here the author is making an assumption, backed by
field observation and the findings or the !Instituto de
Pesquisas e Experimentaqi~o Agropecuarlo do NJorte, Eclem!!,
para'. Hills states in his article "'The Interior of British~
Guiana a~nd the Myl~th of El Dorado" (Canadian GErc~raphe, II,
19~61, 34) that the R~upununi sav.annais are mierely~ an appe.ndaige
of larger Roralmna or A~lto Rio Branco savannas. Those work-,

investigations by~ the Regional Research Centre of the
B3ritishi Caribbean (an organization based ini Trinidad which
car-riedi out ex~tensiv.e soil sampling in Rulpununi in the late
1950's) a number of generalizations, and ha\.e arrived at
three main groups of intergrading soils. The author is
assuming that these generalizations hold for the Alto Rio
Branco as w.ell. The possibility of this being an erroneous
assumption is acknowledged.

One of the key factors of modern exchange societies is

the rapid and efficient distribution of goods and information.

This is largely determined by the quality of highw~ay and

waterw;ay' networks, dependable mail and telegraph systems and~

by' the existence of an7 informed populace instru~c:ced bl' mass

media such~ as radio, television, and newspapers. For those

in Roraima, access to markets, goods, and information is most

difficult. The converse is also true for those mecrely. wish-

ing to travel to Roraima, or more significantly, to establish

business relations, or ship bulk items to or from the area.

The Territory of Roraima is within a region where, until

a relatively short time ago, the only mode of transportation

outside its boundaries was that of river navigation. As if

this were not enough of a limitation, travel was, and still

is, further impeded by the fact that during the "summer"

(i~.,the dry season which occurs from September to M~ay)

the waters of the Rio Branco fall so low that they eliminate,

for all practical purposes, commercial transportation.

The possibility of constructing a road or a railroad

connecting Mlanaus and Boa Vista has long been under considera-

tion. In a public address, the governor of the State of

Amazonas in 1905, referring to the construction of a railroad

connecting Manaus and Boa Vista, remarked inter alia:

In addition to the rail line I mentioned
to you previously, the contract was signed,
by virtue of Law 493 of October 23, 190O5,
w~ith the engineers Hlumberto Saboia de
Alburquerque and Hermano de vasconcelos
Bittencourt, for the construction of a
railroad which, starting from Campos Sales, ends
at the Jauaperi River. Upon reaching there,
by decree number 775-A of April 30 of the
same year, a decree which w:ill opportunely
be submitted to the consideration of this
Congress, the line would be extended to Boa

Guiana) together with the difficulties caused by the dry

season and the numerous river rapids, stated: "If thie piro-

ject of the construction of a railroad from Manaus to the

Rio Branco were executed, this river would experience an

extremely rapid colonization."3 Once again, no railroad

and no rapid colonization along the Rio Branco came into


More recently, interest in reducing the isolation of

the Alto Rio Branco has intensified. In 1938, however, a

civil engineer, Raimundo Pereira da Silva, issued a

cautionary statement concerning the current desire to improve

travel and communications between the city of Mlanaus and Boa

Vista and the region of the Alto Rio Branco. After thorough

studies and the organization of a project (complete w:ith a

budget) for perennial stream navigation on the entire course

of the Rio Branro, from its delta into the Rio LHegro to th-e

confluence of the rivers M~au and Tacutu abov~e Bosa Viista, he

felt able to state that the clearing and channeling of the

Rio Branro's course was phy'sicallyl quite feasible and might

ha.e far--reaching economic conisequences. It would,,

be too great an expense, in his opinion, for the reallities

of this backwaerd region w.hich, although it did have' num~ero~us

and vast potential rich resources, did not ylet have a popula-

tion large enough to represent economic production capable

of justifying the huge capital investment necessary to under-

take such a project.4

Ev~en though the pessimistic v.iewe expressed byl Pereira

da Silv.a and others has continued to the present dayl, the

Brazilians have begun to carv.e a road through the rainforest

in an effort to bring Roraima out of its isolation. This

undertaking will be discussed later in this chapter.

The time necessary for human travel to Roraima has been

drastically reduced by the advent of commercial and military

air transportation. Boa Vista is now~ directly accessible

via the Brazilian airline Cruzoiro do Sul from Manaus three

times weekly, and Georgetown (Guy'ana) weekly'. While

this has facilitated human access and the carriage of mail

and h ig h-a lue,/10w-b-ulk g oods shipments of building materials,

most consumer goods, and cattle remain prohibitivelyl ex-

pensivc owingj to re_7atil. e isolation or inaccessibilityl which

remains as Roraima~'s major impediment to joining the modern


Travel and com~munication difficulties present a serious

hindrance to ccenomic anid administrative activities. Those

living in the sa\annas of the territory become completely

ilhadas, that: is, isolated, during the rainyl season because

all roads and manyl of th~e air strips become inulndated.

Similarlyl, during th~e dryl season, Boa Vista faces grave

shor-tages ofi supplies ow.:ingj to thle extr~emely~ low level of

the Rio Branlco which becomes unnavigab-le.6

Even in terms of nic miles from Boa Vista to populated

areas representing markets and centers of industrial pro-

duction the region's extremely isolated situation is easily

discerned. (Figure 4)

To emphasize the absolute lack of access by land and

discontinuous modes of ingress and egress bj, other routes,

each category of transportation and communication may now be

considered separately.









River Transportation

Even though the airplane has brought the territory

closer to a major center, i.e., Manaus, in terms of travel

time, the river still r-emains as Roraima's life line with

thie exterior. As a transportation route, however, the river

leaves much to be desired. During the rainy season, M~ay

through- August, navigation is possible without hindrance from

M~anlaus as far north as Caracarai, a distance of some 420

miles. From Caracarai to Bsca da Estrada, a stretch includ-

in~g ma~ny rapids, navigation requires a very experienced and

skilled rive.r pilot whlo has a detailed knowledge of these

r-apids. Froml the latter point to Boa Vrista na.igation is

on~ce again free from hazards. (Figure 5) During the eight

m'1onLh dry season several sand beaches and islands appear as

th~e level of the river recedes. Accompanying this allu-:~iation

there is constant movement and relocation of navigable chan-

nols, making passage extremely difficult (Figure 6)

On the passage between Manaus and Boa Vista the average

trip upstream requires eight to ten days and the trip dow:n-

stream four or five days during the rainy season when the

river is at high levels. During the dry season anywhere from

15 to 20 days are required to ascend from Manaus to Boa Vista

while the return run takes from eight to ten days.

The Rio Branco During Dry Season

A view from Boa Vista looking southw~estward. This
portion of the river at this time is navigable only
for small craft. Further south, rapids impede
nearly all traffic at this time.

On the lower Rio Branco' launches and motor boats of

about fivle tons, dlead weight, and of shallow draught haul

barges which can carry cargoes of 50 to 60 tons. On the upper

reaches of th~e river the transports are generally smaller and

carry lesser loads.

An immediate consequence of the disrupted nature of the

navligation and the small load capacity of the river crafts

is the high price of commodities in Roraima caused by the

highi cost of freight. Since almost nothing is therefore pro-

duced in th-e territory and practically everything must b~e

imnport~ed from the ex3teri~or, the cost of living in Ror-aima

inevcitably h-as to be very high. It is not; at all unusual~7 to

pay' at least double wh:~at one would normally pay' in Rloo de

Janeiro or Shio Paulo for the majority of consumer items.


To date, the Alto Rio Branco does not have any roads

which allow access to the area from the exterior. This,

coupled with the seasonal problems of navigation, has kept

Roraima in isolation. Yet after hundreds of years of dis-

cussion and expectation,1 an all-wseather road is now, in

fact, being carved through the rainforest of Amazonia.

It was felt by many that the first link of a highways'

from Mlanaus northward to the Brazil-Venezuela border should

be a stretch of road connecting Caracarai and Boa Vista.

The village of Caracarai is located at the head of that

stretch of the Rio Branco which is freely navigable. From

Caracarai to B~ca da Estrada, a fluvial distance of some 30

miles, the smooth flow. of the river is interrupted by a

series of rapids and low falls, formed by resistant granites

and gneisses w:hichi outcrop in this area. From Baca da Estrada

northwa:ird the- river is once aIgain navigable for vessels hav-

ing a shallo:-' dr-aught. For at least eight months of the yecar

Caracarnii fu~ct~ions as Eoa Vrista's port. Prior to the exis-

tence of the IBca V.iSta~-CarTacar-ai road, supp~llies which arrived

in Caracarai frLomI fln .;us '.-'ere taken overland to Bica da

Estrada whe!lre they~ wer~e once again placed aboard waterciraft

for tr-ans-ship~ment to Boa Viista.

By virtu~e of the signing of Presidential Decree Number

18,50,9 of lNovembe~ljr 23, 1928, the Benedictine missionaries who

were in th~e territory initiated the road on behalf of the

Industrial Company of Rio Branco, which belonged to the

Monastery~ of S~io BEnto. This work progressed only a short

distance and was ultimately abandoned. During 1944 and 1945,

wrhen the road project wras renewed under the governorship of

Enio Garces, it was pushed further southward but still did

not reach Caracarai. After another halt in construction the

road finally reached Caracarai during the summer of 1948-1949.

The stretch approaching Caracarai apparently resembled a

trail. This road underwent tw~o more cycles of abandonment

and reopening in 1950 and 1953.

The principal reason for the slow and spasmodic con-

str~uction of the Boa Vista-Caracarai road was primarily poli-

tical. W~hen the National Highw~ay' Plan (Plano Rodov/iario

unc~~ional) was formulated in the 1940's, at least one road in

each of the territories in the A4mazon Basin, which would be

considered vital to national interests, wlas planned by' the

federal go.errnment. Unfortunately,, in the study of the dis-

tribution of the Na~tionsal H~ighw.ay Capital Fund, the Na~tional

Cong~esss ex;clu~ded the territories from the pr-iv.ileges of

draw.;ing funds from this source. Fur thermor e, thee D~epar tment

of National Highw1.ays (Departamento N\acional de Estradas de

Rodagens) w~as unable to undertake construction of roads in

the territories w~ith its allotted sum from the Ndational High-

w~ay Ca ital Fund because those tentative roads w~ere not in-

cluded in the program entitled the Plan of Primary Urgency

(Plano de Primeira Urgencia) which was also the brain-child

of the National Congress.13

The construction of the road itself has been no small

feat: considering the meager building resources at hand and

the terrain over which the road has been established. The

first stretch of the road, from Boa Vista to the Rio Mlucajai,

a distance of 35 miiles, passes savranna landscape, sav.e

the final two miles to the river, which is through dense selvra.

In order to make this road usable throughout the y~ear, how~- (i.e., during the rainy season as well as the dry sea-

son), it was necessary to construct eight one-lane bridges

(obras de arte) ovrer streams and then to face the problems

of travelrsing the Rio Iducajai, a river of considerable size

and depth~. (Figure 7) It w~as decided that, given the sparse

population and traffic flow it would serve, a bridge would be

too costly to construct. The solution was to install a barge,

pow'.ereld by1 a motorized auxiliary craft, capable of transport-

ing fully-10aded trucks, one or two at: a time, dlepending on

thie si~ze of the truck;. figuree 8) From the Rio Mucajai to

Caracarai th~e road has been sliced through 55 miles of jungle,

crossing no less than 15 streams and shallow lakes, breaking

out onto savanna once again only four miles from Caracarai.

Until recently the entire 94 miles of this road was used

onlyl during parts of th~e dry~ season. Today,, the

situation has changed. Presidential Decree N~umber 61,599 of

October 24, 1967, published in the Official Journal of the

Union (Dliario Oficial da Uniio) on October 26, 1967, has

secured the political means to execute the Preferential Plan

of Federal Road works (Plano Preferencial de Obras- Rodoviarios

Federal), giving absolute priority~ to the program of the

opening and implementing of fundamental roads needed for

national security/, economic development and the infra-

structure essential to the process of settlement, agricul-

tur-al production, and the betterment of health. Included

within thiis plan are the highw.ays BR-174, N~anaus-Boa Vista-

Vrenezuelan border (in the direction of Santa Helena), with

a branch to Lethem in the Repuiblic of Guyana and BR-319,

P3r~to velho-IMa-naus, which will integrate by highw~ay the State

of Ama~lZonas and the Terr-itolry of Roiraima to the rest of the

nation. (See Figure 5).

From the point of .iew of Presidential Decreei f)umber

61,599, highw~ay DR-174, w.hich will exrtend a distance of 582

miles (9~70 k~ilometers), has as its objectiv.e the more inten-

si.e exploitation of an extensive area of the extreme northern

section of the Br-azilian frontier. It is thus hoped that th-e

pezop~le~ of this region wJill bring about a permanent and con-

tinuous interchange with other areas of B~razil. As a part of

the international plan, the highwJay system described here

will form a section of the alter-nativ.e link of the Pan Ameri-

can Highw.ay System, connecting the Brazilian highway network

to bordering nations, initially with \.enezuela and ultimately

wJith the Republic of Guyana, the latter being called BR-401

(Boa Vista-Republic of Guyana), with a length of 84 miles

(140 kilometers).1

The actual implementation of these road projects is

well under ~ay, but construction moves ahead haltingly,. That

portion of the Mlanaus-Boa Vista-Santa Helena highw:ay (BR,-174)

which is to pass from Boa Vista northward to venezuela is

being constructed by a unit of the Brazilian A~rmy, a unit

created specifically ; for this particular undertaking. From~

Boa Vista to Manaus the project is headed by the Department

of National Highw~ays (DNER). The riv.alr; existing betw.een

these two organizations leaves the Braziliain Armyl unit wijth

decided advantages. The physical region thrLough wh~ich, theI

Army. must build a road is, on the one hand, mostly. open~

savanna. Much of the surface material is laterlite and

nearby there are igneous inselbeirgs offering good .;urfaicing

road metals. DNER, on the other hand, must build its portion

of th~e road through some 400 miles of dense tropical rain-

forest. (Figure 9) Less is known about this region and

materials suitable for surfacing the road must be brought in

from distant areas.

Advanced planning for the road has been minimal. Owing

to a paucity; of accurate accounts of terrain, surface

materials, stream drainage, and human settlement, financial

budgeting for this project has been most difficult. The

first phase of constructing highways through the rainforest

has been first to study photos from aereal traverses. Next,

It is through this terrain that BR-174 must pass be-
tween Manaus and Caracarai.

a small rigit~-of-w~ay is cut through the forest to permit

survey;ors to determine the topography~. The right-of-lay y is

thecn widened and thie surface is pushed into a road wiith the

aid OE huge bulldozers and earthmovers. After the surfacing

of the~ road w~ith~ crushed rock~, the final stages of construc-

tion atre the building of bridges or the installation of

ferries. Funds are requested from the federal government

onl; ?.hen it b~comies evident how much~ money will be required

to conpiece ea~ch, regmenlt of the road.

Since the beginning of the actual construction of this

road, rBrazll has been governed by its military~ establishment.

Thus i~t fol.low~s that: in the competition for road-buildingy

funds the federal government teldss to favor thie military~ unit

responsible for thle segment of road stretching from Boa Vista

to B~razil's border w~ith v~enezuela. Th~is has, in fact, proved

to bec so an~d this section should be completed by the end of

1970. Thie only major obstacle is that of bridging the Rio

Uraricoera, a project not yet begun. Partly because of the

difficult in procuring funds and partly because of difficult

terrain and hostile Indians, the section of road being con-

structed by; DN~ER is at least three to four years from comple-


The secondary roads servicing the cattle area of Roraimna

are passable for only part of the year, that being the dry

season. These "roads" range from roads comparable to that

stretch which passes between Boa Vista and Caracarai to what

in the United States would be labelled "'trails" or "'wheel

ruts." Even in the dryr season travel on these secondary

roads becomes difficult because of passage through small

streams and low, swampy depressions.

Air Transportation

It stands undisputed that it was the airplane which

brought Boa Vista closer to the city of Manaus, the former's

nearest Brazilian urban neighbor. From a jaunt of several

days of trav~elling by river, the airplane has reduced the

travel time between Boa Vista and M~anaus to 100 minutes.

From as early as 1945, Boa Vista has been served by

regularly scheduled flights out of M~anaus byl the company

Servigos Aereos Cruzeiro do Sul, Ltda. In December 1953

Cruzeiro do Sul inaugurated an international service to

Georgetown, Guyana from Manaus, with a stop at Boa Vista.

Today the original DC-3's hav~e been replaced by a Japanese-

produced turbo-prop passenger liner having a far greater

passenger and cargo capacity than its predecessor. Boa Vista

now receives flights three times w~eeklyr from Mlanaus, two of

which go on to Georgetow.n and return the same day.

In addition, the Brazilian Air Force constantly flies

into Boa Vista, bringing troops and supplies to the army

battalion stationed there, as well as vehicles and materials

destined for both military and civilian use. It is in truth

the Air Force which is responsible for the operation of the

airport at Boa Vista.

The airport itself is small but. modern. The runway, ic

paved, kept in excellent condition, and, since it measures

6,500 feet in length (2,000 meters) by 131 feet in wlidth

(40 meters), is capable of receiving most jet aircraft,

even though it is not on the jet run at the present timie.

Moreover, this particular airport serves as a base for

several single-engined aircraft used by ranchers, diamond deal-

ers, and missionaries and the old amphibious twin-engined

Catalinas, which are used byl the Brazilian Air Force to dis-

tribute troops and supplies to border areas, to deliver mail,

to carry essentials to Indian tribes, and in general to

serve the public.

As part of a chain reaction, Mlanaus has also greatly

increased its contacts with the highly developed regions,

such as Rio de Janeiro, Brasilia, and Sio Paulo to the south.

The result has been that such things as newspapers and maga-

zines now reach Boa Vista from as far away as Sao Paulo and

even P~rto Alegre within two days.

With respect to human travel time, spread of information,

and shipment of high-value/lowJ-bulk items, the advent of the

airplane has obviously been a boon to Roraima. Yet in terms

of development and the free flow of goods and services to

and from the region, air travel has not proved to be the

definite and final answer.

To the great majority of people living in Roraima Terri-

tory the equivalent of $25.30 U.S. necessary for a round-trip

to Manaus by air is beyond their means. Thus, M~anaus remains

for them several day~s tral.el by uncomfortable river navilga-

tion. The cost of transporting essential goods such as rolls

of barbed wire, heavyl machinery, consumer goods in bulk; quan-

tities, animal feed supplements, and others by air continues;

to be prohibitive. Finally, the practice of bringing in much

needed fuels such as bottled gas and gasoline by air Is: for--

bidden. It stands, then, that while air transportation has

made great strides in bringing Roraima Territory~ out of iso-

lation, other lines of access must be improved or implemented

before this remote area of Brazil's N~orth can effectively join

the nation.

5These excruciating circumstances have plagued the in-
habitants of FRoraima continually from the beginning of
settlement in the 1700's. See, for example, a petition to
the government given by the Chamber of Commerce of the State
of Amazon~as in 1.940, expressing itself as follows:

Another problem to solve in the area of beef
cattle activities in the state is the transport
of cattle for slaughter from the distant
ranches of the Alto Rio Branco to the city of
Mlanaus where the majority of the consumption
takes place.

Despite the expensi.e and unsuccessful
attempts to construct a road, without appro-
priate planning, which claimed a heavy
sacrifice of federal lands, the difficulty
of transport, in the present situation, is
one of thie'major obstacles to the compensating
utilization of the large herds which exist
there. Diverse formulae and suggestions hav.e
been proposed byI technicians and studious
types, some favoring the construction of a
railroad and others favoring the planning

of a highw~ay. All, how~ever, have not been
accompanied by series of meticulous studies
which require further understanding. With-
out a doubt, the solution to the problem
of shipping cattle from the Alto Rio Branco
to Manaus lies in one of the-se tw~o w~ays or
a combination of both, wlithh the help,
furthermore, of river navigation. It seems
the opportune time for us to ask the govern-
ment of Your Excellency to study this
important question, from its several angles,
in order to decide upon the best solution.

Commerce of Amazonas (la naus Ama zonas) 1940, p. 63.

6While the author- was residing in Boa V'ista, in the
month of March (1969), he witnessed a resultant shortage of
sugar, coffee, pow..dered milk, k~er-osene, gasoline, bottled gas,
and beer. SevJeral of the author's trips to ranches in the
interior had to be temporarily postponed for lack of gasoline.
Indeed, it is most difficult to carryl on economically~ and
admin-istrativelyr with the occurrence of major interruptions
caused by material shortages.

7Obviously, and compar-ed w~ith Boa Vista, ITanaus is
indeed a major center (population 244,000 in 1967), buc: it
also suffers from isolation. Located some 1,000 miles up-
stream from the Atlantic Ocean and Beleom, its nearest urban
neighbor in terms of accessibility, Manaus is the commercial
center and capital for the State of Amazonas (898,000), with
a population density~ for the entire state of 0.02 inhabitant
per square mile. For a detailed discussion of the subject,
see: "The Functional Relationship of M'anaus to the Amazon
Basin." Unpublished dissertation (Univ.ersity of Florida,
1969) by Jerry R. W~illiams.

SThe late deputy Antinio Mlartins, in a speech delivered
before the Chamber of Deputies on October 7, 1947, expressed
the seasonal difficulties of navigation on the Rio Branco and
the resultant human hardships as follows: "It should be
pointed out that the lower Rio Branco, in its course of 400
kilometers, starting from its mouth, is only navigable with-
out great hindrance from Mlay to August up to the village of
Caracarai, on the right bank. In the remaining eight months
of the year when the river's volume of water is considerably
lower, navigation is permitted only to small engines, hauling

barges with reduced tonnage and having a draught of not more
than two and one-half feet, devoid of the most. fundamental
elements of comfort and hygienee"

9The lower Rio Branco is that portion of the rivecr's
course from its juncture with the Rio Negro northward to
Caracarai. The upper Rio Branco is that part of the river
lying north of Caracarai, passing Boa Vista to the point
where the Rio Uraricoera and the Rio Tacutu merge to become
the Rio Branco.

10Reference is made in Clovis Nova da Costa (O Vale do
Rio Branco to the length of time that better access to the
Alto Rio Branco has been considered. He states:

Whoevrer writes the history of the Rio
Branco will ha.e to reserve a special.
chapter to the Boa Vista-caracarai road,
whose attempted construction dates back
to the se'.'enteenth centurl when the
problems of transport stimulated the
imagination of the pioneers, looking for
the solution to the difficulties of access
and the fl.ow of production. The funda-
mental stage of the daring project of con-
necting Mlanaus and Boa VJista by road, only
after two hundred years of expectation, is
that which opened the expected w~ay of com-
munication, within a day~'s journey~, whose
principal facts we layr aside here (sic),
as the contribution to the history of the
major undertaking of the sort now: accom-
plished in the basin of the Rio Branco."
p. 130.

11The Brazilian planners have had a complete change of
rationalization with respect to highways construction.
Witness the thinking of Raimundo Pereira da Silva (see page 43)
as being typical of previous thinking. Prior to building
a road through an area there had to exist already a popula-
tion large enough to generate economic production capable
of justifying the allocation of capital necessary. to carry
out such an endeavor. The result of a turnabout in this
policy is v/iv~idly' brought to light in Dav~id Crease's article
on the new road connecting Belem andBasla (Jong
the Two Brazils," Geographiical M~agazine, XXL~VII I, No. 59J
(July' 1964), 184-197). The town of Imperatriz, some 500

miles up the Rio Tocantins in the State of Maranhdo, northern
B~razil, had a population of 6,000, one truck, and no road to
the exterior in 1960. By 1964 the Belemo-Brasilia highway con-
nected Imperatriz to the exterior both to the north and to
the southi. The 6,000 people there have now become mnore than
20,000. The rice crop has ju~mped in a few~ years from 8,000
sacks to 500,0001 The monthly count of vehicles ini transit
through Imnperatriz nowl exceeds 1,000.

1For example, the engineer, M1. Pacheco de Caralho, upon
studying the transportation problems of the territoryr, ex-
pressed his thoug~htsas follows:

Thle solution for the normal transport of ev~idently the construction~
of a road connecting Caracarai to Boa Vista
which would allow transport by truck from
Carcarari to Boa Vrista in four years. Seeing
that the land is flat or gently rolling, it
allows the construction of a road the
best qualities.

The construction of this road, whiich is of
vital federal importance since it is part of
BR-17 [no BR1 brings to mind the
colonization of the forest which runs alongside
the major part of its extension.

This was a note on the connection by highwlay between Boa Vista
and Caracarai as a stretch of BR-17 (unpublished) draw.n from
G~uerra, p. 234~.

In another statement by Dr. Pacheco de Carvalho, who was
also ex-director of the Dil.ision of Construction and Conservra-
tion of th!e Departmrent of N~ational Highways, he stated: "Att
this time the most necessary task is the construction of a

referring to the importance of that road, has said:

The Boa Vista-Caracarai road constitutes

the axis of a system that will guarantee
the circulation w~ith the economy of the
bordering countries. From there, i.e.,
Boa Vista, there will be the construction
of another road, parting fr-om the capital,
on the left bank of the Rio Branco, going
to Concega~o do IMau, on the border with
British Guiana. Later, with a branch~ in
the direction of Santa Helena, r'enezuela,
the economies of the basins of the Amazon,
Demer-ara and Orinoco will become joined.

Historical BackgrouncJ

Given th~e cultural background of the people andl the

nature of the physical milieu, it is not at all surprising

to find that exten~sivee livestock rais~ing has a~lway~:s been the

predominate economic activity on t.he sal.'ann~ias of Rtorailuia.

Latin Amrericanists have long recogrniZ~d th~at in7 tlhO Luso-

Hispanic colonizationi and de*.relopment of t!,0 j:n.Cricas cattle

raising has played ani important role.

It is a well documented fact th~at the entire system of

large-scale livestock raising was imported to the N~ew world

from the Iberian Peninsula.1 Cattle have been raised almost

everywlhere in Europe and America, but raising cattle and

cattle ranching are not the same thing! Bi shka provides a

definition of the latter by stating that ranching "implies

the ranging of cattle in considerable numbers over extensive

grazing grounds for the primary purpose of large-scale pro-

duction of beef and hides.2

Historically, as an extensive productive activity,

ranching required large tracts of grazing land and more

specialized techniques than those required for the care of a

few dairy cows or small herds which served as an adjunct to

agriculture. With the possible exception of the Hungarian

Plain and western portions of the British Isles,3 mnedieval

Iberia appears to hav.e been the only part, as it w~as un-

doubtedly the most important part, of medieval Europe to ad-

vance to this third level of cattle raising.4 Although the

precise circumstances are still obscure, the available

charters (cartas) and statute-law~s (fueiros) provide evidence

that a genuine ranch cattle industry evolved in the Iberian

Peninsula in the late elev/enth and twnelfth centuries, under

Alfonso VI and Alfonso VII of Leon-Castile. The birthplace

of this activity was that portion of the subhumid or arid

interior tableland of the Me~seta Central lying between the

middle course of the Duero (or Douro) River and the mountains

of Gata, Gredos and Guadarrama.

From this area of origin, cattle ranching, on an ever

expanding scale, spread southward along with the reconquista

colonization. By the late twelfth century~ it had moved into

the broad pasturelands of New Castile, Extremadura, both in

Spain, and Alentejo, in Portugal. Alentejo, by all available

accounts, is the cradle of the Portuguese ranching system

which was later extended into Algarve, the Archpelago of

Iladeirn and the B~razilian sertao. On the southern half of

thec mcsetai, primarily to the west of a line passing through

central new Castile, Castilian and Portuguese military orders,

noble,~- s and tow.nsmec n grazed thousands of cattle, although in

b~oth~ numbers and economic importance these w~ere less signifi-

cant thian the great sheep flocks of the blesta and other

owners. But this situation wias reversed after 1250, with~

Ferdlinanld II~i's reconquest of Andalusia, when royal regarti-

mienton~c assigned to cattlemen r~ather than sheep raisers the

bulk: of the extensive lands in the valley~ of the Guadalquivir

Rivr. s a result, theC Anldalusian plain (including part of

the PorLtuglueses Alentejo district) became in the latter Mliddle

Agejs the- on-e region of the Penin-sula, and perhaps of al~l

Europe, where pastoral life, and indeed agricultural life

in generall, was dominated by a thriving, highly~ organized

cattlel-ranchiing economy. The fact that, many of the early

colonists of the Canaries and the islands of Nladeira, and

later. the N~ew world, came from these southern Iberian cattle

kingdoms, which were at their heights in the fifteenth and

early sixteenth centuries, provides one significant clue

to the~ promotion of cattle over sheep ranching in the

American colonies.5

Th~e types of cattle found in early Castilian and

Portuguese ranching were most likely the results of various

degrees of crossing between lighter-colored European types of

the all-purpose cow~ and theT w.ildl or semi-wild, black, dark

r-ed and dark birown descendacnts of a cattle strain unique to

Iberia, Bos taurus ibericus, the ancestor of the modern

fighting bull. These tw:o str:ainss mingled on the meseta and,

as the reconquista frontier:'~ wasush~ed southward, these tw;o

razas produced a v~ery-1 hardly Ilybri~d s~ock~, displaying an

;Imazing variety~ of color anld color comb~-inations from cream-s,

yellowis and gray~ish~~~-b:rons to deep b~rownis, reds and blacks,

This wias a stock charact~erize- d by:, markredly feral instincts

and of ten complete w~ildness. Su]ch cattle were :aluable

chief~ly for their tough hicdes andi str~iingy b-eef. These

cattle then, unlsuited for aniry or draft purposes, comnpelled

those w;ho pursued this producti.e aciiltivit in c'astile and

Portugal to abandon their "'cozy. little rolwpastures" for the

open range, to take to thr. hors~e for her-ding, to perfect

systematic methods of long-distance grazing (or eien traJns-

humance), periodical round-ups, branding, overland drives,

etc.--in short, to invent cattle ranching!

Across the sea in the ~ew~ WJorld, the Spanish found, i

what is now: northern M~exico and thie United States' Southw;est,

an area similar in many, respects to thie Ilese-ta C'entral, i.e.,

a semi-arid grassland poorly' suited to the growing of crops.

Being accustomed to the dry plains of Castile, the Spaniards

wer-e quick to realize the geographical limitations and

adapted thelmselves to the conditions of climate and topography

which~ theyc; enco~unteredd in the Americas. Liv.estock raising

presented a means for utilizing the available natural re-

sources to provide a liv.elihood and food supply~ for those

settlers w:illing to enidure th~e hardships of pioneer life.

In North Amiier'ica the Spanish Crown issued land grants

which co~rrsp-ondedd to the requ~iremenits of the cattle industry.

Far bJe~ttr tha~n the A~ngjlo-Amnerican~s, the Spaniards recognized

the need for largo tracts of land for grazing and pasture.6

w~alter~ Prescottl Hobc~b pointed out in~ his classic study~ of the

Great Plaj~in that the An3l~o:

thought in terms of the possibilities of
utilization and production. To him a
hundred acros was a sufficienc,.....No
pL~roirtion had been made in lawI for the
ranchmanc~ wh~o was using or trying to use
the semi-arid land.7

On the other hand, thle Spanish authorities, with ex-

per-ience in Elemi-a~rid environments, took into account the

climate and proposed land use in determining the size of the

land grants. The grants reflected either agricultural or

pastoral use; land suitable for irrigation and farming was

divided into small units, whlile dry land and pasture were

allowed in larger portions.8

The rise of ranching in Spanish Texas, as investigated

by' S. L. yrel'rs, wacs quite sim~ila7r to the course of the intro-

duction of ranching into Inoraila.' In northern M~exico the

Spanish system of landholding led to the establishment of

the haiciendia, a huge landed estate inl the possession of one

family that approximlated the feudal holding of Europe-. The

hacienda, not Infrequentlly containing more thian 300,0003

acres, became a self-suffic-ient oconomiic un~it which~ included

farming, mining, and a niumbr~h of commner-cial enterprises in

addition to stoch:raising.; Som~;e of th~e largest estat~es were

communitiesi in themsllves,'is withi field-s, filck~s anld herds,

wooded areas, flour: mills, forgos~c and wo~rk~shlops. Each had-

its church and so-.eeral hun~dre:1 o- e.len thousands of in-

habitants, w~ith v.illages foi the Indian~s and~r w.oreri~S, as

well as the casa de back~ndai o,.cup-ied byl thle haicendalo~ and

his family.

In Texas,, thc Spran~ish '.e're forced to adapt their

methods of stockraisi~ng and lan~d utilization to frontier con-

ditions. Common pasturet anrd stockraising grants pro\.ided

grazing for large her'ds of li-.estock on the grasslands and

dry' plains, while the rivecr I.alley~s an~d well-w~atered areas

were reserved for farming and aIgriculture.10'

In addition to the individual land grants, collectivJe

holdings were available. For many centuries, the towns of

Castile and Portugal had been landholding bodies possessing

more or less extensive territories belonging to the towrns

and admiinistered byl their officials. Such lands included

proprios, rented out for cu~ltivation; e~jiidos, reserved for

a v.ariety of purposes such as dump grounds and slaughtering

pens and not used for buildings or cultivation; and debosas

or baldios, common pasturage on vacant lands in the open

range.1 Stockmen pastured animals on baldio lands under

license from the .icer-oy or governor until such~ time as thle

lands w~ere granted to individuals. In Tex>as ag~r~eements wecre

occasionallyr worked out between mi.-sioniaries and townspeople

as to the extent: of grazing p~rivileges on the dehosa betweeni

the Guadalupe and San Antonio rivers.12

During the period of early Spanish~ settlement, desp~it~e

the pleas of the Church, the missions in Tex:as were not

opened until Spanish borders w~ere menaced byl the French.

Then, and only then, w~ere the missionaries allowed to begin

their wcork and garrisons w~ere constructed and ranches w~ere

established to protect and support them.

within this context it is important to note the develop-

ment of ranching as an appurtenance to the garrisons,1 those

tiny outposts of the Spanish Empire charged w~ith the responsi-

bility of protecting the missions and w~ardin'g off the rush of

intruders--French, Indian, and English--who desired to prey

upon Spanish possessions. As one of the most isolated of

Spain's frontier domains, Texas was far removed from main

communication and supply routes, and scarcity of food,

clothing and equipment plagued presidial commanders and pro-

vincial governors throughout the colonial period. Ranching

offered a partial answer to these problems not only by pro-

viding meat, but also oxen for plowing, mules for hauling

provisions and supplies, and horses for mounting and main-

taining the garrison troops.14

Contrast the introduction of ranching into the far-

flung Texas region of the Spanish Empire with the rise of

this same activity in wJhat is now Brazil's Northeast.15 The

history of the growth of cattle ranching in the Northeast,

beginning with the arrival of the first heads of cattle in

Salvador from the island of Madeira, is intricatrely tied to

the settlement of that region's interior. It was the breed-

ing and grazing of cattle, more than any other activity,

that promoted the advance and settlement of the Portuguese

into the Brazilian sertio. The entradas and the bandeiras

only exploited the region for Indians which they would sell

into slavePry along the coast, or they scoured the area look-

ing for mineral wealth and wer'e merely temporary dwellers.

The objective of each adventurer and miner was to make

his fortune as quickly as possible and return to the city so

that any settlement by these types of individuals was, at

best, of a temporary n~tur~e. On the other hand, the men wlho

were founding fazendas for cattle raising moved into the

interior continuously and in a "one-way"" fashion.

The lands w~ere obtained from th~e Portuguese Crow~n by

means of grants which wrere known as cartas do sesmai. 16

The actual amount granted wac~s called a sesmaria. A4t the

samie time thiat: the nobles wer.e dealing w.ith the authorities

in the sitting rooms of the Viceroy in Salv;ador, or the

Governor of Pernambtuco in Olinda, seeking final agreement on

the lands whose occupation theyr had been promised, the vagueiros

were receiving the word from those same nobles to push on with

land settlement as far as possible...''into all of th~e interior

of Bahia, Pernambuco, Alagoas, Sergipe, Rio Grande do iNorte,

Ceara, Piaui, large parts of Malranhao and Mlinas Gerais."l

With the passage of time the nobles received more cartas

de sesmaria and took possession of their newly acquired lands,

therebyl creating extensive latifundios. One example of the

benefactor of sesmrarias is the Grupo Garcia D'Avila, today

the wealthy family of the casa de Torre, in Salvador. This

family w:as so successful in accumulating lands that their

fazendas extended from coastal Bahia on into Piaui, Pernambuco

and Ceara. Along the banks of the Rio Sio Francisco, for

example, this family owned some 320 miles of land. They

owned territories larger than most European countries.l

Land distribution through crtas de sesmaria w~as dis-

criminatory; and unecqual. The r-ight of ownership was granted,

with grim consistency, to those who knew~ nothing about the

land. The process of granting the land,, done

in a somewhat orderlyl~ mannier. The Portuguese Cr-own declared

that a fazenda would consist of three leagues' distance

(approximat~ely 12 miles) along a gi.en wa~tercourse.

would be one leaguec of landc left between fazendas so that

there w~ouldr' be no quel~sti~on about the property lines of a

given piece of land.l

Population con~tinued' to inc;-ease along the coast and

the resultant demand for me-at :;1 too large for th~e existing

ranches of th-e interiocr to fil~l. It was the ev.ergroowing

demand for meat tha- garve rise to thie rapid growth of the

fazendas in the inter-ior. Th-is numierrical increase greatly

facilitated byr the extremely1 simple manner in which a fazenda es tabl ished. l that was:~ necessary~ was to build a

crude straw shelter for the .agueiro and hiis helpers, or

his family'; construct a .coryl crudre cor-ral where theyl would

place the cattle for the pur-pose of former os cascos, a

period of quarantine to tame the unruly, cattle for easier

handling on the range; after this the cattle wJould be turned

out into the w~ild caatinga, leaving them to feed themselves

and reproduce with almost no human care. In this way a

fazonda was established and a stretch of land about 12 miles

along a watercourse was "settled."

In a very narrow sense of the word, fazendeiro is

sylnonymous w.ith~ the owner of a fazenda. But in the early

times the landowners livecd on th~e coast andl only received

new.s and pLrofits occasionally from their fazendas. Thus,

for all practical purposes, it can be stated that the first

fazenidoiros that established themselves in th-e Northeast

we.~re the wiild ulaqu~eiros, pioneers who, with the cattle that
they received from the quarteacao, leased lands and began

ranch~ing for themselves.

Trhe rent from the sitios, leased lands generally a

squa~re league each (43.57 square kilometers or 16.8 square

miles, or 10,762 acres), was about 10 mil reis per year.

Th~is was during a period when one steer was worth- about tw~o

mril reiss so that payment corresponded to the value of five
steers per year.

In retrospect, the vaqueiro brought the cattle into a

given area, took on all the risks and performed all the

neces~saryl tasks of operating a fazenda, and finally saw co

the settlement of the leased area for which he had worked

10 to 15 years to obtain, often leasing for a high price

the very land that he himself had "conquered."

On a fazenda, initiated in this manner, the workers' lives

differed from those who lived on the large landed estates.

The former vlaquciro, upon establishing his ranch, was not

able to pay anythlin-g to the workers, who most often turned

out to be his children, who carried out the tasks of the

fabricas (~el~pers to the vaqueiro).

Trhe I;stem of qu~alrteac47~ o gve rise to a new class of

people in the sortho. Considering that there had been a

chiangc: onilyj in the name, to fazendeiro, from :aqueiro, to

en t r l: ep er uer fromn laborer,. but w~ith~out the possibil~ity of

pay'ingc~ :.or-kers, and the specific chlores were still the same,

thie p-oferr-ed namle f~or these fazendeir-os was fazendeiros de

yagueiro aiit~nomro.- It: should also be added that the

fazendeciirro de~- vaglueiro aut~jnomeo did niot care for his own

cattle any better than hie had cared for those belonging to

his f~ormeor Pa~traO.

whieni fcld crops began to appear on the fazendas it

became necerssary to build fences. The faizendeiro nowr

wocrriedl abouti his crops so that the cattle wer-e left: to

roam mnore unattended th~an ever, but now fenced in on one

part icul~ar fazenda. The use of fences brought an end to the

practice of apjart~apcio (rounding up and sorting out cattle

that had grlazed in common but w~ere owned by different

fazendeiros) because the cattle no longer bred and grazed on

common pasture.

As wars true throughout the A~mericas in the history of

ranching, the appearance of fences brought on a miore sophis-

ticated form of cattle ranching and gav.e new~ importance to

the fazendeiro de vaqruairo aut~nomo, w~ho tried to purchase

the lands he had been leasing. If the fazendeiiro lived in

a nearby~ city, he superv~ised a system of for-eman!;hip in ad3-

ministering the affairs of the fazenda, and he himself

tended to business in the city, such as acquiring breeding

stock, seeds and equipment, and selling thact which his

fazenda had produced.

W~hen the change came to the fazendas to the ad.ent

of fences, the v~aquciro capstazi the foremnan of the city-

dwell1ing faztender ro, began receiving his salary in cash.

This occurred because the fazenda began a phase of more

sophisticated lil.estock; ranching, utilizing a system wh:ereby

it was possible to improl.e the quality of the herd by cross-

ing the cows with newly purchased breeding bulls. When the

quality of the cattle impro'.ed, the fazendeiro was no longer

interested in sharing his stock with his foreman by means of

the quarteaqio. In this way the -aqueiro experienced an

increase in importance of role on the fazenda but in economic

terms he was demoted because financially his real salary

turned out to be worth less, thus greatly reducing the possi-

bility of his owning his own fazenda.

The origins of cattle ranching on the remote savannas

of Ror-aima have been obscured by~ time. At best, historical

accounts and eividen~ce of this are ex~tremcly sketchy and tend

to conflict with~ one another. HoIweverI while some of the

specific information is lackling, the general purpose and

pattern of establishiiing r:.nching as the primairy economic

activity~ in this regjio~n can be~ clearly' di~scerned. The early

situation in Roi~raimal beairs a sci-ron resemblance to wJhat had

occurred a century~ earlier in ,rpanish- Texas. The areas of

the upperu Rio Ne]glro, the~ Solimoes, anrd what is now\ R~oraima

werce regJions whi~erec the: colonial interests of Spain, Port-ugal

and the Dutch hadi cla~shed duringr the sevenentcnth and

eighteenth centuries..

There are fleeting rcefeences to European penetration

into the e:tireme nrorth of Br,~aziil in the eighteenth century,1

but the intentions o~f the5 earlly Intruders were not those of

establishirrg permanent settlement. For- example, Lawrence

Belfort, a wcealthy; Irishi entr-eproneur who had settled in

Mlaranh o, tra\elled to the interior of Amazinia seeking

slaves as labor for his various agricultural enterprises.

On one particular occasion, in 1740, he reached the valley

of the Rio Branco.2 Nicholas Hortsman, a German represent-

ing the interests of thle Dutch on the northeast coast of

South America, contacted the Indians of the R~io Negro in the

year 1741 by passing diown the Rio Branco system,24 advancing

from the Essequibo Region, which, at that time, w~as Dutch

territory anid later became a British possession.

Thle Treaty of IMadrid~ in 1750 w~as arranged to settle a

dispute b~etweren the Spanishi and Portuguesc Crowns which

centered on thle Plata region, but the regions of thle Or-inoco

and Ne~gro drivers far to the north w~ere not insensitive to

this highly tentarlivel agreement. As a result of thiis treaty,

Fr-anciso :av~ier de Me~ndonga furtado, Go'.ernor of the~ Cap-

t~aincy of Grand Paira, w~as appointed by the Crown~i as the prin-

cinal comm~iissioner- for- boundaries of the Ndorth in 1752.5

Hle was~ charged w.ith thie du~ty of meeting a Spanish expeditionary

Leam~ to delimit the boundaries in Amaz~nia between the Spanish

and portuguese possessions.26 The Treaty of M~adrid was de-

claredi nuill and v~oid in 1761 and tw~o yeare prior to t-hat

flendonsa Furtedoo had returned to Portugal, ne'.er having ful-

filled his boundary-delimiting mission.

The Treaty of Santo Ildefenso, in 1777, produced another

commission to fix the boundaries between the Spanish and

Portuguese possessions in the New World. The Portuguese

Crow~n appointed Joao Pereira Caldas, Gov~ernor of Grand Para,

to head its commission. Caldas took up residence in Barcelos,

the seat of the Captaincy of Sao Jose do Rio Negro, and

worked vligorously for a number of years there attempting to

promote'economic activity and permanent settlement which

would aid the Portuguese in their claims for extended bounda-
ries. Upon suffering a stroke, Caldas was replaced by his

former assistant in Grand Para, Mlanoel da Gama Lobo d'Almnda,

Governor of the Captaincy of Sayo Jose do Rio Negro.

Lobo d'Almada wias a most ambitious man. He explored

the upper Rio Negro and discovered major tributaries connect-

ing that river with the rivers Ja ura and Solim~jes. He

brought sparsely scattered Indians into settlements, he

developed the agricultural industry~ of growing mandioca for

the production of farinha, he acti;ated indigo grow~ing~ w.ith

an eye to shipping it to the European market, and he en-

couraged settlement in the savannas of the Rio Branco.2

As early as 1775, Spanish forces invaded the savanna

area in Roraima and began to establish a garrison to fortify~

the Rio Uraricoera.29 The Spanish had entered this area

seeking the fabled lake of El Dorado. The Portuguese sent

a force out fromn Barcelos led by Filipe Strum, a German in

the service of Portugal, which drove the Spaniards out that

same year. Besides forcing the Spaniards back, Strum seized

this opportunity to select a site and construct a fort to

defend the Rio Branco savannas from further intrusions by

the Spanish or the Dutch. He selected a site on the left

bank of the Tacutu river where it joins the Uraricoera to
