EVALUATION OF SOME ALTERNATIVES FOR ECONOMIC DEVELOPMENT OF
EXTRACTIVE ACTIVITIES IN ACRE, BRAZIL

Reconciling conservation with the improvement of living
conditions among communities settled in the Amazon forest has
been a challenge for the communities themselves, the Brazilian
government, and national and international NGOs. Despite the
great interest in this issue among scientists, development and
conservation agencies, and politicians, uncertainty prevails
regarding the actual deterioration of Amazon ecosystems and
the improvement in living conditions of the communities
involved.
Creation of extractive reserves in Brazil was an attempt
to resolve the issue. However, after years of
experimentation, neither forest conservation nor improvement
of the rubber tappers' living conditions have been achieved;
deforestation is increasingly accentuated within the reserves,
while the communities confront severe economic hardships.
xiii
This dissertation examines proposals to improve the
economic viability of extractive activities conducted by
families in the Antimari State Forest, Acre, Brazil. One
strategy was to diversify the product base, exploiting under-
utilized resources and developing markets for new products
extracted from the forests. Extraction of timber and non-
timber products was examined as a major additional activity.
Farming systems methodology was used, including
participatory observation of the activities in each household.
Factors limiting production were identified and a set of
alternatives drawn, including timber forest products such as
lumber, and non-timber forest products such as heart-of-palm,
essential oils, and handicrafts. Using linear programming, a
simulation of the current situation was constructed as a base
to analyze other alternatives. Sample households were sorted
into five categories according to their primary economic
activities (and income levels), as well as location within the
reserve.
Findings demonstrated that rubber extraction is not a
profitable activity and should be replaced by more valuable
products. Potential for sustainable timber extraction and
exploitation of non-timber products was demonstrated under
appropriate conditions of property, production infrastructure
and organization, sustainable management, post-harvest
processing, and transportation and marketing. Revenues from
these products could increase the gross return per unit of
labor input up to ten times the current levels.

CHAPTER 1
INTRODUCTION
The deterioration of traditional extractive economies
based on Brazil nut and rubber collection threatens the
sustainability of extractive reserves in the State of Acre,
Brazil. Threats to the viability of extractive reserves
include:
* Net returns from current extractive activities are too
low.
* The market prognosis for rubber is unfavorable.
* The current market, concentrated in a few extractive
products, is volatile.
* Extractive activities are labor-intensive and
inefficient.
* Deforestation rates are increasing as rubber tappers turn
to farming in an effort to recover lost income.
A typical individual production unit, called a
"colocag&o," involves approximately 300 hectares. Within
this area, a family gathers rubber and Brazil nuts while
engaging in small scale farming, fishing, and hunting
activities.
Because of the diminishing returns from extractivism,
rubber tappers are increasingly driven to agricultural
practices, thereby exacerbating deforestation in Acre.
Alternatively, rubber tappers and Brazil nut gatherers flock
to towns and cities, where their illiteracy and lack of job
skills prevent them from gaining access to all but menial
employment. In either case, people live in extremely poor
conditions.
If forest resources are to be maintained and human
populations meet their basic needs, the economic viability
of extractive activities must be improved. One way to
achieve this is diversification of the product base, which
entails exploring under-utilized resources and developing
markets for new items extracted from forests.
Producer communities and support organizations have
little information or guidance concerning appropriate
products needed to diversify the extractive production
system. This study focused on several potential products
that could be used as alternatives to the current production
system.
General Hypothesis
This dissertation examines the hypothesis that
alternative forest products are viable, from technical and
socioeconomic perspectives, in order to diminish the current
deforestation rates in the state of Acre, Brazil. The
success of these alternatives will require certain
institutional conditions that currently do not exist.
Objectives
This research was based on a linear programming
optimization procedure used to simulate current household
activities, supplemented by forest inventories, and a long-
term management plan. It analyzed more profitable and
sustainable conditions under which household members could
utilize the forest to diminish the current deforestation
rates in the Antimari State Forest (ASF), in the state of
Acre, Brazil.
A historical view of the main aspects concerning the
role of extractive activities in the Amazon and an
assessment of their weaknesses and strengths as alternatives
for conservation and income generation are examined in
Chapter 2. Chapter 3 describes the study site at the time
the research was conducted, as well as the methodology
utilized.
The results of the market study, compiled from
inspections of 11 Brazilian market centers, are presented in
Chapter 4. Chapter 5 outlines the general characteristics
of the ASF community and differentiation of five homogeneous
groups of families (population structure, household
activities, age and gender roles, and calendar of
activities).
In Chapter 6, different options for the improvement of
the extractive economic activities in the ASF are analyzed.
Utilizing optimization procedures, the current situation is
4
first simulated for each of the homogeneous household
groups, then alternatives for improving the situation are
described, simulated, and analyzed. Finally, Chapter 7
presents the research conclusions, discussing the
feasibility of the recommended alternatives within both
local and regional frameworks.
CHAPTER 2
A REVIEW OF THE ROLE OF EXTRACTIVE ACTIVITIES IN THE AMAZON
AND THE ALTERNATIVES FOR IMPROVEMENT
Introduction
Historically, the role of extractive activities in
tropical areas has been considered crucial in some periods
and marginal in others. Among Amazonian development
alternatives, extraction of non-timber products still plays
an important role in some areas, while extraction of timber,
agriculture, cattle ranching, and mineral exploitation are
the basis of the economy in other areas.
Although often associated with depletion of natural
resources in areas of low population density, extractivism
has coexisted harmoniously with the native forest for a long
time. However, drastic changes in the Amazon's population
stimulated by migration, economic dependency on a few
products with fragile markets, and the active incorporation
of the Amazon into national and international interests,
have imposed enormous pressure on areas with extractive
activities.
The controversy over extractivism in sparsely populated
areas involves two opposing views. First, there are those
who believe extractivism is an inefficient land use,

stimulated by migration, economic dependency on a few
products with fragile markets, and the active incorporation
of the Amazon into national and international interests,
have imposed enormous pressure on areas with extractive
activities.
The controversy over extractivism in sparsely populated
areas involves two opposing views. First, there are those
who believe extractivism is an inefficient land use,
occupying areas with potential for intensive livestock
production or agriculture. Second, there are others who
consider extractivism an initial model to achieve
conservation of biodiversity, while preserving the Amazonian
lifestyle and achieving long-term economic sustainability.
In this chapter, major aspects concerning the role of
extractive activities will be examined. The extractive
activities that should be pursued in the future will be
identified, with the purpose of establishing linkages with
conservation and development of the Amazon. To reach the
established objective, three aspects will be considered: (1)
the historical evolution of extractivism; (2) the main
objections to extractivism as an inefficient land use
practice; and (3) the alternatives to improve extractivism
as a potentially sustainable practice.
Economic Settlement of the Amazon and Extractive Activities
Miranda Neto (1985) divides the economic settlement of
the Amazon into five phases: the conquest (1500-1750), the
occupation (1750-1850), the rubber cycle (1850-1946), the
valuation (1946-1966), and the integration (1966-today).
Episodes of boom and bust of extractive products have
occurred during economically decisive periods in the Amazon.
The Conquest
The conquest phase was characterized by the extraction
of resins, fibers, oils, and medicinal plants, and the
production of cocoa, sugar, and indigo (Indigofera
suffruticosa). This phase was dominated by the mestizo
society derived mainly from Portuguese men and indigenous
women. The economy was subordinated to the metropolis of
Lisbon with very little interaction with other Brazilian
areas.
The most important primary resource products during the
colonial exploitation period were: cocoa, Brazil nut
(Bertholletia excelsa), and fish; spices such as
salsaparrilla (Smilax officinalis) and copaiba (Copaifera
multijuga); aromatics such as panquile (Piper cavalcantei)
and tonka bean (Dipteryx odorata); narcotics such as iage
(Banisteriopsis caapi) and virola (Virola sp.); stimulants
such as guarand (Pranceana cupana) and xexua (Sterculia
sp.); and fibers such as piassava (Leopoldina piassava) and
malva (Urena lobata).
The Occupation
The occupation phase was conducted for the purpose of
stimulating agricultural enterprises and integrating the
Amazon into colonial trade as an exporter of primary
resources. The political integration of Para and Amazonas
into the rest of Brazil following its independence in 1823,

The Occupation
The occupation phase was conducted for the purpose of
stimulating agricultural enterprises and integrating the
Amazon into colonial trade as an exporter of primary
resources. The political integration of Para and Amazonas
into the rest of Brazil following its independence in 1823,
produced social instability and disaggregation of the
initial productive system. Thus, some activities continued
to be developed in the Amazon, while others were
discontinued or moved to other areas. Coffee cultivation
was switched to regions near the Brazilian capital, while
cacao plantations were developed in Bahia. Finally, during
the first half of the 19th century, the Amazon returned to
extractivism based on the collection of rubber.
The Rubber Cycle
According to Miranda Neto (1985), four events
characterized this phase: the creation of the Amazonas
province in 1850, the introduction of steam navigation, the
extensive exploitation of "seringais" or rubber estates, and
the arrival of immigrants from the Northeast.
These events boosted the rubber economy, since they
increased the importance of the traditional economy
characterized by both extractivism and the export business.
As a consequence of this cycle, forest occupation became
crucial. "Ouro negro" fever began, and the the Acre
territory was annexed to Brazil. Profits benefited the
exporters, while the rubber tappers grew poorer due to their
dependence on traders and other external agents. Rubber
tappers were not able to meet their needs, as food had to be
imported. The high revenues generated by rubber were
concentrated in the hands of the elite, who unfortunately
wasted the profits and failed to create a resilient and
diversified economy (Weinstein, 1983).
In spite of a high demand for rubber in the
international market and the increase in rubber prices,
Brazil, its sole producer, could not increase the supply due
to both labor and capital shortages (Dean, 1987; Barham and
Coomes, 1994). Meanwhile, northeast Brazil suffered not
only a crisis in its sugar economy, but also a
transformation of the livestock production system into a
subsistence economy. This scenario worsened after the long
dry season of 1877-80 that forced more than 65,000 people to
migrate to the Amazon (Souza, 1994).
Because rubber activities were pursued exclusively,
other agricultural and extractive enterprises were
completely abandoned. River navigation and other activities
connected to rubber transportation were developed. In 1866,
three large national navigation lines were established and
the Amazon River was opened to foreign navigation.
Subsequently, The Amazon Steam Navigation Company Limited
absorbed the existing national lines. The trade of goods
and services contributed to the growth of Belfm and Manaus
as main ports (Miranda Neto, 1985).
Capital scarcity gave rise to the "debt-peonage"
(aviamento) system, based primarily on foreign capital. In
the aviamento market system, goods were supplied on credit
at inflated prices and were paid for in extractive products,
mainly rubber. Since the rubber merchants or patrons
(owners of the rubber trails) paid low prices for extractive
products, while the prices of food, clothing, and medicine
soared, rubber tappers were almost always in debt. In this
system, the overriding objective was rubber production, and
all other subsistence activities were clearly subordinated
(Allegretti, 1979). However, a recent point of view
justifies the aviamento as logical, not really exploitative.
"Debt-merchandise relations" between tappers and traders (or
patrons) provided the most efficient way of reducing the
barriers posed by high transaction costs and risks for these
extractive activities (Barham and Coomes, 1994).
The aviamento involved a long chain of debtors.
Merchants and patrons themselves were usually also in debt
to downstream merchants, who in turn, were indebted through
marketing banks to wholesalers and exporters and ultimately
to foreign banks which supply seed money (Richards, 1993).
In the literature, two reasons are given to explain the
traditional social relations that persisted during the boom.
Both are based on the relative power of patrons and traders
versus tappers. One reason suggests that the relationship
with tappers as debt peons, serfs, or slaves was maintained
by force or coercion through threat of violence (Dominguez
and Gomez, 1990). Patrons and traders whose profits
depended on exploiting workers had little to gain by passing
on to workers the benefit of price increases or by altering
the production structure for extraction or trade according
to the wishes of a foreign purchaser.
The second explanation, offered by Barbara Weinstein
(1983), argues that tapper resistance, not coercion,
conditioned the nature and durability of social relations.
Rubber workers preferred the autonomy of wild rubber
extraction to the drudgery of wage labor and effectively
managed to resist proletarianization. Their resistance was
encouraged by two important features of the industry.
First, the extracted rubber was, by law and in practice, the
property of the tapper and not of the owner of the land and
trees. Second, the high cost of monitoring the working
tapper strictly limited the degree to which patrons could
truly control their workers or curb illicit rubber sales.
Between tappers and traders, on the other hand, a lasting
alliance developed based on interlocking self-interests--the
traders' need to control the exchange of rubber and the
tappers' preference for autonomy--that effectively
frustrated local and foreign pressures to rationalize rubber
extraction and trade.
According to Coomes and Barham (1994), the most
significant way to improve the Amazonian rubber industry
would have been to introduce large-scale rubber plantations
similar to those of the Asian model. Furthermore,
plantations were attempted and failed for environmental and
technical reasons (Dean, 1987). Weinstein's view of labor
relations offers another explanation as to why this effort
failed in the Amazon: he contends that plantation
development was blocked by the lasting tapper-trader
alliance. The dismal failures of foreign firms operating
wild rubber estates with disappointing yields are well
known. Tappers apparently worked at a slower pace or failed
to report all the rubber tapped, selling part of it to
itinerant traders (thereby benefiting both themselves and
the traders). This mutual bond of self-interest brought
both parties to a stalemate; tappers controlled production
but not exchange, and traders controlled exchange but not
production. Any effort to force tappers to work more
intensely would diminish their autonomy and provoke
resistance. Further, the low density of wild rubber trees
also guaranteed tappers a degree of autonomy they could not
enjoy in a plantation.
Complementing Weinstein's point of view, Coomes and
Barham (1994) affirm that labor scarcity, mobility, and the
high cost of monitoring tapper effort and output were
empirical features of rubber production. These features ob-
viate the classic portrayal of tappers as debt peons, serfs,
or slaves kept in these relationships by coercion.
In 1876, before the auto industry boom, rubber seeds
were taken to England and then to Ceylon and Singapore.
Subsequently, in 1900, the first rubber plantation in Asia
was under way and the Brazilian rubber monopoly came to an
13
end. By 1913, Asian production was twice as large and less
expensive than Brazilian production, forcing the Brazilian
rubber price to drop from 512 in 1911 to 100 per ton in
1913-14 (Weinstein, 1983).
Due to the Brazilian rubber crisis in the international
market, people in the Amazon reverted to extracting products
from other species such as Brazil nut, balata (Manilkara
bidentata), South American palm oil or caiau61 (Elaeis
oleifera), piassava, and babassu (Attalea phalerata). When
Japanese immigrated to the Amazon, black pepper (Piper
nigrum), jute (Corchorus capsularis), and vegetables were
incorporated into the regional agrarian economy.
In 1942, during World War II, the Japanese tried to
seize control of the Asian plantations, and the allied
countries were interested again in Amazonian rubber. The
USA and Brazil signed an agreement to rapidly increase
rubber production, but when the war was over, the USA did
not buy more rubber and a new collapse beset rubber
production in Amazonia (Weinstein, 1983).
The Valuation
The goal of the valuation (1946-1960) period was to
achieve territorial occupation of the Amazon; to build an
economically stable and progressive society; to strengthen
the Amazon economy; to initiate some kind of agriculturally-
'According to Smith et al., 1992
14
based economy in previously selected areas with satisfactory
transportation systems and natural resources; to develop
industries in the cities; to utilize the forest and mineral
resources in moderation; and to improve extractive
techniques as well as the forest workers' quality of life
(Miranda Neto, 1985). However, these goals were not
achieved:
From the late 1940s to the early 1960s,
income from rubber gathering had fallen from 8% to
5% of the regional economy of the Amazon. Even
so, extractive activities in general, including
tin ore and gold prospecting, the hunting of
pelts, and the gathering of Brazil nuts, still
occupied 60 percent of the regional labor force.
Rubber was an element key in sustaining these
other survival stratagems because it was
government funded. (Dean, 1987:131)
The Integration
Starting in 1966, the federal military government
developed policies towards to integrate the Amazon into the
rest of Brazil. These policies were based on the
consideration that the Amazon is a large isolated and
underoccupied area, lacking in national security provisions,
and, in addition, a source of products and services for the
entire country (Schmink and Wood, 1992).
The PIN's (National Integration Program) first phase
was the quick construction of the Transamazon and Cuiabd-
Santardm highways. On both sides of the highways, a narrow
area was designated for colonization. After 1970, the
government's view of the Amazon changed: no longer a problem
area, it was now perceived as a pioneer area in transition.
This point of view stimulated private and government
investments in minerals, timber, and livestock with poor
social results. As the economic border expanded, local
people faced land expropriation, which forced them to either
submit to the new enterprises, look deeper in the forest for
new land, migrate to urban areas (thus swelling the marginal
population), or try to resist expropriation (Miranda Neto,
1985; Schmink and Wood, 1992).
In the north of the Amazon region, the population
increased from 330,000 in 1872 to 7,650,000 in 1985 (14
million in the entire Amazon region) (Benchimol, 1985).
Although today 65% of the population in the northern region
is concentrated in the urban areas, many people live from
the forest and shifting agriculture. In 1980, it was
estimated that 68,000 families were involved in rubber
tapping, distributed in the following states and
territories: Amazonas (32,300), Acre (23,200), Pard (8,300),
and the remainder (4,200) in Rond8nia, Amapa, and Roraima.
Assuming an average of five members per family,
approximately 340,000 people were directly dependent on
tapping native rubber trees for their livelihood
(Allegretti, 1990).
Currently, rubber tappers are living in either
autonomous or debt-peonage economic systems. In the
autonomous system, a family's or group of families'
16
landholding ("colocagAo") produces a mix of both subsistence
and market goods (Allegretti, 1979). This mix generally
consists of one or two regionally commercialized products
such as rubber (Hevea brasiliensis) and Brazil nut, combined
with other forest products of more restricted occurrence,
such as copaiba, a medicinal resin, and sorvinha (Couma
utilis), another type of latex. Alongside extraction of
forest products, families practice a shifting cultivation
that generally includes traditional crops such as manioc;
crops that can substitute for industrialized goods, such as
tobacco and sugarcane; and both native and exotic fruit
trees. The autonomous rubber tapper also engages in
economic activities such as the gathering of native plants
(for example, fruits and heart-of-palm of the assaii" palm--
Euterpe precatoria--and medicinal plants), as well as
fishing and hunting.
Extractivism As Inefficient Land Use Practice
The relatively large holdings required by rubber tapper
families have been cited as a major weakness of extractive
land use systems. "Given the naturally dispersed
distribution of most marketable forest products in tropical
forests, extractive systems typically require relatively
large continuous tracts of forest land" (Browder, 1992:176).
In addition, Anderson (1992: 69) asserts that "if land were
distributed throughout the Brazilian Amazon according to the
rubber tappers' standard, the current population of the
region would have to be reduced." The average size of a
rubber tapper's extractive area currently varies between 200
and 1,500 hectares, depending on the region. In eastern
Amazonia, it is difficult to calculate the average size of a
caboclo2 household, since the Brazil nut stands do not
belong to a specific family but rather are common property
or are claimed by a large landholder.
Although one of the most important objectives for
promoting the extractive land use system was the improvement
of the rubber tappers' standard of living, the decline has
continued, even after the emergence of the Brazilian Council
of Rubber Tappers and the legal recognition of numerous
extractive reserves. Among the reasons cited are the
increasing subdivision of holdings and the resulting
"superexploitation" of individual rubber trails in order for
households to retain their purchasing power. To offset
progressively lower income from rubber tapping, some
households have increased the area of annual crops,
producing deforestation at higher rates than in other areas
where commercial agriculture, not extraction, prevails
during the same period (Browder, 1992).
According to some surveys done in the extractive
reserve of Cachoeira in Acre, extractive production based
mainly upon rubber and Brazil nut faces several fundamental
2Riverine people of primarily mixed European and native ancestry
problems, such as low rubber quality, lack of price
guarantees, low rubber and Brazil nut prices, lack of
infrastructure for processing, increase of pasture areas,
and economic dependency on what remains of the aviamento
system (UFAC/UF, 1989). The low return to producers is
partly the result of costly and risky transport conditions,
often in treacherous weather conditions, and the high risks
of marketing extractive products in a hyper-inflationary
economy (Padoch, 1989).
The aviamento system is still practiced in many forms
throughout the Amazon. Although its practitioners suffer
from severe deprivation, there are two factors that may make
its replacement difficult: first, its capacity to supply
other necessary products obtained from remote areas; and
second, its production arrangements that force rubber
tappers to maximize the time devoted to extractive
activities (Richards, 1993). Some studies show that gross
returns from traditional extractivism (including only rubber
and Brazil nuts) are less than those some other uses of the
Amazon (Table 2.1), which leads some authors to argue that
the extractive economies are unstable over time and not
indefinitely self-sustaining.

The role of extractive activities is likely to change
in the future, especially because the long-term prospects of
wild rubber in the Brazilian economy are not secure
(Allegretti, 1990). The extractive reserves in Acre have
been sustained by a Brazilian tariff policy that has
effectively fixed the domestic rubber price at roughly three
times the average world price (Fearnside, 1989). However,
due to changes in the Brazilian policy of tariff protection,
domestic Brazilian rubber prices have fallen, and rubber
tappers are increasingly turning to farming to recover lost
income (Browder, 1992).
Perhaps the most important factor currently threatening
rubber production in the Amazon is the pressure of
successful plantations in non-Amazonian Brazil. By 1991,
about 180,000 hectares of rubber on plantations were
reported for Brazil (ITC, 1993), mainly in the states of
Bahia and Sdo Paulo. Browder (1992) estimated that
cultivated rubber supplies 60% of the Brazilian market.
These plantations, which have the comparative advantage of
being closer to the demand centers, will soon be able to
supply all of Brazil's domestic rubber needs at a reduced
cost, and the rubber extraction is sure to decline in a time
when free market policies call for subsidy removal
(Richards, 1993).
Brazil nut collection has generated an important part
of the income from extractive activities due to
international support for improving processing and
commercialization, particularly for improving conditions
among the rubber tappers near Xapuri. Due to the
seasonality of the harvests, Brazil nuts and rubber are
complementary activities with Brazil nut being collected in
the rainy season and rubber extracted in the dry season.
Brazil nut extraction gained in importance after the
rubber price crash in 1910. Because national consumption is
very low, it depends mainly on the international market.
According to the Sociedade para o Desenvolvimento Tecno-
ecol6gico (ECOTEC) (1993), Brazil nut today could reach a
world market share of $67 million due to the "substitution
effect"3 common among the nut markets. However, O'Donnell
(1990) noted that the Brazil nut market share has declined
to less than five per cent of the edible nut market, due
mainly to the growth in consumption of almonds and hazel
nuts. This fact could affect the market share of Brazil
nuts.
The international nut market is very dynamic,
especially as the "substitution effect" increases.
Therefore, besides the difficulties to increase or at least
maintain production to match demand, Brazil nut production
faces an old problem: the aviamento system. Advancing money
and/or commodities is a basic prerequisite for the aviamento
If for any reason there is a decline in the supply of a specific
nut, other nuts take up the slack.
system to succeed. According to Man-Producten Rotterdam
(1991), scarcity of money advances was responsible for the
serious crop reduction in 1991. In that year, Brazilian
shippers stopped advancing money for two reasons: first, as
local brokers found their debts accumulating, instead of
buying more Brazil nuts, they used the money advances to pay
those debts. As a result, nearly 50 to 60% of the contracts
were not delivered. Second, interest rates in 1991 were
very high (30% per month).
The main Brazil nut producers, Brazil and Bolivia, are
competing for market share. The United States imports about
50% of the Brazil nut traded in world markets. From 1991 to
1993, the USA has imported about 3,000 tons of shelled nuts
from Bolivia, as compared to less than 2,000 tons per year
from Brazil (Table 2.2). Partially, this has to do with the
fact that Bolivia's prices are lower than those of Brazil
(labor costs for shelling are lower in Bolivia). In the
case of in-shell nuts, the situation is quite different:
Bolivia has exported lesser quantities than Brazil, and
since 1993 it has exported only shelled Brazil nuts.
The future of Brazil nut extraction may also be under
threat due to a reduction of the resource base. Nepstad et
al., (1993), report a lack of regeneration and a scarcity of
juvenile trees in Acre. Possible causes include over-
harvesting of seeds, a reduced population of dispersal

agents, and low germination rates due to small felled-tree
gaps in Acre's forest.
Other researchers, though, believe in the success of
traditional rubber and Brazil nut production. In a study
comparing production value and ecological costs of different
land uses in Acre, Hecht (1992) found that on average
agriculture, livestock, and extraction generate an annual
gross return per hectare of US $1,200, US $1,350, and US
$1,320 respectively. However, production costs were not
considered in this study, and inclusion of these data would
probably change the results dramatically. Extractive
activities use more labor than agriculture or livestock
production, and their return per work-day is lower than that
of other more intensive practices (Table 2.1).
Since livestock raising has been considered as a little
productive but highly profitable activity, more than $1
billion of highly subsidized credit and fiscal incentives
have been applied to the sector (Browder, 1988).
Furthermore, tax exemptions, land speculation, and capital
gains associated with rising land prices have stimulated
this type of land use (Repetto, 1988).
The state of Acre is a good example of this. The years
from 1960 to 1980 saw major changes in land use and
distribution. Extractive activities declined both in area
(by 65%) and number of holdings, while ranching and
agriculture increased notably, mainly as a result of the
government's policy of frontier development through the
expansion of the road network, resource privatization, and
subsidies (Richards, 1993).
Starting in 1970, the Acre government supported an
intensive propaganda program in southern Brazil, mainly Sdo
Paulo, to attract both national and international capital.
Acrean lands were offered at very low cost, particularly to
livestock producers, and generous financing was provided
through SUDAM (Regional Development Superintendency) (IMAC,
1991).
"Land cleaning" operations, meaning the removal of
rubber tappers and small farmers, became common from 1973
onwards as ranchers intimidated rubber tappers and bought
their land at very low prices. This development, coupled
with the deterioration of rubber and Brazil nut prices, led
to an intensive outmigration from rural to urban areas.
Whereas in 1970, Acre had had 57,790 inhabitants in cities
(greater than 2,000 people), by 1980 the total population in
these cities had reached 131,000, and by 1991 the figure was
255,000. Rio Branco, Acre's capital, had seen an increase
from 35,000 people in 1970 to over 89,800 in 1991 and to
167,457 for 1991 (IBGE, 1991). The rural population
decreased from 56% in 1980 to 38% in 1991.
The urban migration process was accompanied by rapid
deforestation. The area deforested in Acre increased from
77,000 hectares in 1975 to 552,000 hectares in 1989 (INPE,
1989). In an attempt to improve the living conditions of
the rural populace, governmental and even some international
programs spent a lot of effort supporting agricultural
activities. However, the ecological and economic results
are far from viable.
Agricultural research in the Amazon has focused on
solving the constraints of agriculture using external
models, without considering more appropriate local
production models. Thus, most of the effort has been
directed at soil and environmental problems in an endeavor
to develop continuous cropping as the only alternative to
shifting agriculture.
In the 1960s an ambitious research program began in the
Peruvian Amazon with an agreement between the government and
the University of North Carolina, the goal being the
development of intensive agriculture in the Amazon based on
the knowledge that: (1) the Amazon has 345 million well
drained hectares, with slopes of a less than 30%, which
represent one of the world's biggest reserves for crops,
livestock, and forestry under rainfed conditions; and (2)
75% of the Amazon's soils are oxisols and ultisols, 15% are
entisols of fluvial origin, and only 6% of the well drained
soils (Altamira, Porto Velho, Rio Branco, and the eastern
Ecuador) have a high natural fertility Therefore, an
adequate knowledge of the soil's chemical properties was
imperative. The final justification for developing the
27
Yurimaguas project was the high environmental impact of the
agricultural system utilized by local farmers in forested
areas: their slash-and-burn method consisted of clearing the
forest and cropping the land until native fertility provided
by the ash was depleted, which took only a few seasons, and
then moving on to the next area (Cochrane and Sanchez,
1982).
Several cropping systems and time-of-planting studies
were conducted at Yurimaguas with maize, soybean, groundnut,
rice, and cowpea to determine the most promising systems of
three crops per year. Unfortunately, continuous monoculture
of the same crop did not produce sustained yields because of
the adverse effects of climate and a population increase of
various pathogens (Valverde and Bandy, 1981).
According to Bandy and Sanchez (1982), many of the
drawbacks of continuous monoculture were eliminated by using
crop rotation. The most promising results so far were
obtained by growing three crops per year on a rotational
basis (upland rice-maize-soybean or upland rice-
groundnut-soybean). After ten years, the average yields per
hectare were 2.71 tons of rice (37 harvests), 2.81 tons of
maize (17 harvests), 2.3 tons of soybean (24 harvests), and
3.46 tons of groundnut (10 harvests). Both production
levels and economic returns were acceptable.
However, because investment and the cost of inputs are
too high, these results are not applicable for most farmers
in the Amazon. The cost of the fertilization plan for one
year (Table 2.3) is US $875/ha (Cochrane and Sanchez, 1982).
These fertilizer levels do not differ substantially from
those required for maize, soybean, and groundnut cultivated
in the ultisols of the southeastern United States. The
problem with these figures in the Amazon, however, is that
fertilizers, lime, credit, and an adequate market system are
not available (Arguello Arias, 1988).

In spite of the enormous difficulties of implementing
the results of agricultural research in the Amazon, some
projects have attempted to encourage rubber tappers to use
this model as an alternative to extractive activities.
Projeto Esperanga (Project Hope) in the state of Amazonas
moved 100 local rubber tapper families to a planned 300
29
family settlement of agricultural colonists. After only two
years, 80 colonist families were left, due to the poor soil
conditions and the unsuitability of the agricultural
technology promoted by the project (Melone, 1988).
The deserted farms are usually bought by ranchers who
consolidate large tracts of land. Permanent employment on
these ranches is quite limited since livestock raising is
not a labor intensive activity. When the pastures become
degraded, the human carrying capacity of the area drops even
further. Most of the scientific community argues that most
of rural Amazonia simply cannot support a large population4
(Fearnside, 1989; Weischet and Caviedes, 1994).
At this point, it is clear that more intensive
agriculture could intensify difficulties for people who have
historically made their living from extractive activities.
Taking into consideration that the continuation of small
scale agricultural practices involves a lower risk for these
people and would keep the environmental impact at a minimum,
extractive activities might continue to be the main focal
point. This approach has attracted attention, especially
after the creation of extractive reserves in Brazil in 1990.
In spite of the lack of research on improving extractive
activities, some experiences show that there is economic
4There are however, some ecologically exceptional areas with
relatively fertile soils in the vicinity of Altamira, Porto Velho, part of
the state of Acre, and the Amazon floodplain.
potential for extractivism, particularly if developed in
areas where people have historically depended on it.
Alternatives for Improving Extractive Activities
According to O'Donnell (1990), there are four
alternatives for improving economic returns from extraction.
The first is to enrich the forest by planting economically
valuable plants and removing competitors, the second is to
utilize the natural high densities of certain tree species
which are scattered throughout the Amazon region, the third
is to increase the value added to forest products before
they leave the reserves, and the fourth is to increase the
number of species that are extracted.
Taking into account that extractive activities are not
isolated from subsistence agriculture and that there is
always some area of the production unit dedicated to this
activity, any improvement must cover both extractive and
agricultural activities. This realization leads to an
examination of the possibility for developing agroforestry
systems.
Another more recent alternative, pointed out by Clement
(1993), is the creation of income-generating forests in the
Amazon. This approach would involve most of the
alternatives considered above and could be applied both to
non-destructive harvesting of a large number of existing
31
species and to the introduction of species into the standing
forest or previously degraded fragments of it.
Enriching the Forest by Planting Economically Valuable
Plants and Removing Competitors
The experiences gained in the Peruvian Amazon
(Hartshorn, 1990) and Suriname (De Graff, 1982) could serve
as models for low intensity forest management. In these two
cases, the key to sustainable production in the different
types of tropical forest is clearly an adequate pace of the
forest's natural regeneration. There are two groups of
techniques that encourage such regeneration. The first
ranges from extreme treatments such as clearcutting, usually
in strips, followed by tending of natural regeneration, to
less drastic interventions that include the preservation of
a certain amount of cover ("shelter-wood") and, finally,
very conservative or cautious steps towards creating
openings within the forest (Budowski, 1988).
The second group of techniques combines natural
regeneration with artificial plantings that enrich the
forest with small amounts of valuable seedlings. Logging
practices often create favorable conditions for natural
regeneration, but at present most timber exploitation
schemes are not very concerned about existing seedlings,
saplings, and pole trees of desirable species (Budowski,
1988).
32
Hartshorn (1990) has been working with the first group
of techniques. His system produces systematic gaps in the
forest by clearcutting and carefully extracting the
resulting products in strips 20 to 50 meters (50 to 150
feet) wide. Only a small fraction of the forest is strip-
cut each year, allowing the gaps to close and making it
possible to return to the same plot after 30 years. The
system has been used in the Palcazd region of the Peruvian
Amazon, which receives abundant rainfall. Early results
show that there is abundant regeneration and initial growth
is excellent, not only of seedlings from adjacent trees, but
also in top regeneration of trees that were cut. Marketable
trees are locally processed in sawmills and treatment plants
for poles and posts.
This project is based on collective management by the
indigenous community, which owns the land. The long term
success of the activity will depend, among other things, on
keeping the community interested in all the management
operations, including logging, processing, and marketing,
which should be the case as long as the members receives
direct and continuous benefits from the managed resources
(Kishor and Constantino, 1993).

plant communities that include fewer species than in more
diverse communities (Peters, 1989). Anderson (1992),
Anderson and loris (1992), and Anderson and Jardim (1989)
report the results of research on Combu and Jaguar (Ilha das
Ongas) islands near Bel6m. The vegetation is floodplain
forest that is characterized by a high dominance of a few
tree species, many of which are of economic importance and
form the basis for extractive systems, the most notable
being the assai palm (Euterpe oleracea).
The harvest of assai fruits provides the residents of
both islands with their primary source of cash income, since
the Bel6m market is easily accessible. Other sources of
family income include lumber, heart-of-palm, shrimp, rubber
on Jaguar Island and semi-wild cacao on Combu.
The average size of a family holding on Combu is 36
hectares. A family generally uses less than one hectare for
a garden and to raise small livestock near the house. The
rest of the holding consists of managed forest, in which the
caboclos plant seedlings of valuable trees and eliminate
competitors through selective thinning. The costs of
production per hectare are approximately 18 labor days,
including one day of hired labor, and $1.44 in material
costs. The annual gross return is over $70 per hectare,
nearly $2,550 per holding, or $4.18 per work-day of family
labor. Again, this compares favorably with average wages in
Bel6m, which Anderson and Jardim (1989) estimated at US
$2.65 per day for 1986. Fewer than 20% of the Combu's
inhabitants are employed off the island (Anderson, 1992).
Anderson and his associates also tested the effects of
traditional forest management practices on the assai palm.
Fruit production from unmanaged forest provides returns of
$235 per hectare per year. Pruning the palms and thinning
their competitors requires approximately ten labor days per
year (an opportunity cost of US $26.50 for potential wages
in Bel6m) and results in a gross annual return of $370 per
hectare (Anderson and loris, 1992). This does not include
the return from the timber which is "thinned" or the heart-
of-palm hearts from the pruned stems.
Hoping to conduct a more systematic search for
extractive reserve sites, the Rubber Tappers Council has
begun a project with the Woods Hole Research Center to
analyze the distribution of forest resources and to identify
areas with high concentrations of economically valuable
species (O'Donnell, 1990). However, the mere existence of
forest resources does not guarantee the success of an
extractive reserve. If there is no functioning market for
forest products or no community organization in charge of
managing common usufruct rights, a reserve is unlikely to
succeed without significant outside assistance.
Increasing the Value Added to Forest Products Before They
Leave the Reserves
The Xapuri Agroextractivist Cooperative (CAEX), in
Acre, built a Brazil nut processing plant with support from
different organizations. In 1994, the CAEX paid US $0.64/kg
of nuts processed by the household units. This figure
applied to Brazil nuts that the CAEX had already purchased
from various gatherers during the harvest and had stored in
the central shed near a mini-factory. However, when
households that operated their own processing unit could
harvest and process Brazil nuts, the CAEX paid US $1.32/kg
(Campbell, 1996).
According to Hartshorn (1990), local processing of
timber for sawnwood, preserved posts and poles, and charcoal
adds considerable value to the native forest products.
Gross returns (after local processing) from natural forest
management by the Yanesha Forestry Cooperative in the
Peruvian Amazon are projected to be US $3500 per hectare
harvested. However, monetary assistance for infrastructure
and training in timber processing and management of these
projects is necessary if they are to succeed.
Increasing the Number of Species That Are Extracted
This initiative makes it necessary to create new
markets, or obtain access to existing ones, and to learn how
to identify, extract, process, and store the new products.

Non-timber products
There are some potentially valuable non-wood forest
products which are currently underutilized, such as wild
cacao, massaranduba (Manilkara elata), balata (Manilkara
bidentada), and piassaba. Sorvinha latex, which has
traditionally been harvested by destroying the tree, could
be sustainably tapped, leaving the tree to produce more
latex and fruits (Prance, 1989). Similarly, there are many
non-timber products that are successful on the international
market at present, or are likely to be so in the near
future. Examples are herbal antioxidants, which now
represent 10% of the antioxidant demand but are projected to
comprise the total demand for these products in the future;
natural food colorings, which now make up more than 95% of
the 100,000 tons in the food coloring market; medicines,
spices, and other natural products involved lately in green
consumerism (Duke 1992).
Oliveira et al. (1993) carried out a survey of non-
timber products used by nine communities of riberinhos in
the Tapaj6s National Forest. They inquired about the most
widely used non-timber species and products, their
collection processes, yield per tree, post-harvest
processing, and commercialization.
The researchers found that the riberinhos used products
from about 100 species; however, only 15 play an important
role in the community's economy. Among the latter are seeds
of cumaru (Dipterix odorata) and Brazil nuts; oils from
andiroba (Carapa guianensis) and copaiba (Copaifera
multijuga); bark of barbatimao (Stryphnodendron
pulcherrimum), pau d'arco roxo (Tabebuia impetiginosa),
preciosa (Aniba canelilla), and quinarana (Geissospermum
sericeum); latex of rubber, massaranduba (Manilkara elata),
amapd doce (Brosimum parinarioides), murure (Brosimopsis
acutifolia), and sucuuba (Hymanthus sucuba); and resin from
jatoba (Hymenaea courbaril).
Oliveira et al. (1993) made an estimate of the annual
production and the gross and net incomes for the riberinhos,
considering that they sell their products either at the
production site or in the Santardm market (Table 2.4). From
the selected 15 products, cumaru accounts for 50% of the
riberinhos' income, due to the high value of its seeds,
which are used on an industrial scale as an aromatizer for
tobacco, chocolate, and beverages and locally for medicines.
The figures obtained by Oliveira et al., based on
selling the 15 non-timber products at the production site,
show a potential net income of $435.16 per ha with a minimum
cost of $2.72 per ha. The figures are also based on the
following set of presuppositions: (a) every tree in the
studied area produces maximum yields; (b) the frequency of
the selected species is the same everywhere; (c) the species
are so closely spaced that one man could exploit 12 trees
per day; and (d) there is a complementarity in the phenology
38
of the species so that during the harvest season competition
for labor will not develop.
In spite of the promising income from the non-timber
species studied, Oliveira et al., (1993) underline that
these communities have their subsistence based mainly on the
practice of agriculture, hunting, and fishing. The apparent
lack of interest on the part of the communities to carry out
the extractive activities studied by Oliveira et al.
suggests that none or few of their presuppositions prevail
and that they overestimate the potential net returns of
these activities. Thus the results of Oliveira et al. have
to be considered carefully.
Medicinal plants
A study performed by Rider et al., (1994) in the city
of Cuiaba (state of Mato Grosso) in May and June of 1994
found a total of 162 vegetative species as sources for
medicinal products sold by 12 herbalists. However, 75% of
these herbalists had in common only 8.78% (15) of all
species found, and only 11 of the species found sold more
than 15 units (bags containing approximately 100 g) per
month, with the bark and seed of sucupira (Bowchisia
virginioides) being the most common (some 31.3 units per
medicinal herbalist per month). The study also indicated
that approximately 52% of the medicinal plants that make up
the marketed materials in Cuiaba are derived from wild
species found locally, while 13% come from Amazonia and 20%

Timber products
It is well known that timber is one of the most
valuable products from the Amazon. However, timber
harvesting presents difficulties due to a lack of planning
in the efforts to keep both the ecosystem functioning and
the communities prospering.
The high value of timber and other forest products
should help ease the transition toward sustained yields, but
the shift will require drastic changes in official policies
for timber concessions, and it may be necessary to offer
incentives to those groups that take effective steps in that
direction (Budowski, 1988). Therefore, the challenge is to
find adequate ways to do it.
In smaller countries, where tropical forests have
been all but destroyed by loggers and follow-on
farmers, the cessation of tropical timber
extraction might be justifiable. However, the
omission of timber resources from discussions of
sustainable extraction in the case of Brazil seems
incomprehensible. Browder, 1992 :181.
Although there is little scientific literature about
successful experiences with systems based on sustainable
timber extraction in the Amazon, there is a potential for
this if properly managed.
Forest management and traditional methods of
exploitation. Many of the small timber producers in the
state of Amazonas use traditional methods of timber
extraction which are responsible for about 80% of the
state's timber production. While these methods have some
limitations, such as low production capacity and dependence
on family labor, from a social point of view, they have
guaranteed subsistence and land tenure for thousands of
families over generations.
The main characteristic of the traditional methods is
their low level of investment and technology. Although
productivity and economic gains are low, the environmental
impact, compared with mechanical exploitation, is minimal
and does not compromise floristic composition and natural
regeneration (Oliveira, 1992). Traditional timber
extraction uses separate methods for flooded and non-flooded
areas.
The harvest of commercially valuable logs in flooded
forests takes advantage of the river floods for extraction
and transport, thereby foregoing the use of heavy machinery.
This system depends greatly on the extraction and commercial
use of low-density logs and does not offer large volumes of
logs with high densities.
All of the techniques employed are based on
generations-old experiences adapted to current situations
and the technology available. Extraction is regulated by a
calendar that allows for the small producers' other
essential activities (hunting, fishing, extraction of non-
wood products, and subsistence agriculture), thus allowing
for a multiple use system of natural resources. Capital
investment is low, reduced to chainsaws, gasoline, a boat
(canoe), and food.
Producers are not organized in labor unions or
cooperative associations. The majority work independently
and alone. Also, there is no structured price control for
producers.
The traditional method of havesting timber in the
flooded areas has four phases: 1) opening trails and marking
trees; 2) cutting down trees; 3) transportation and
"cubicaje" (packaging); and 4) marketing.
Trails are opened with the help of machetes and without
instruments for orientation. Trails are determined by the
possibilities for access to and transport of logs during the
flood stage. Producers thus choose a main entrance to
streams, creeks and lakes that allows access and transport.
The cutting of trees begins after the trails are
opened. The intensity of the tree cutting process is low,
mainly because the selection is restricted to a few species
and large trees.
The transport phase is the most difficult. The log may
be guided with the aid of pushers (sticks forked at one
end), canoes, or paddles, depending on the water depth.
Once the logs are by the river banks, buyers measure
the logs, subtracting five cm from each log's diameter to
43
account for the thickness of the bark. Normally, only logs
with a diameter greater than 35 cm (without the bark) are
taken into account for packing. In July 1989, prices per
cubic meter were about $8 for logs brought to the river
banks and $25 in the sawmills.
As is the case in rubber extraction, the process is
financed by the buyers (patrons), who advance payment in the
form of shelter, oil, gasoline, and medicines at the
beginning of the extracting season. All of these goods are
supplied at high prices, coupled with the patrons' exclusive
rights for selling the product (at low prices).
The traditional method adapted to non-flooded forests
is similar, but there is a difference in the mode of
transportation. Since there are no waterways that could be
used for the transport operations, it becomes necessary to
process the logs at the original site. There, chainsaws
transform the logs into sawnwood. In special cases, a
producer may have available some animals to transport the
logs to sites with more sophisticated processing equipment,
such as a portable saw, which considerably increases
processing efficiency.
Environmental impact. Even though this type of logging
system has a "bottleneck" caused by unequal production
arrangements (similar to the aviamento), it may be
ecologically sustainable. Oliveira (1992) gives examples of
this system of logging production in the state of Amazonas,
where he analyzed the process of floristic succession in
gaps incurred by the exploitation and studied the structure
and future possibilities of natural regeneration and
sustainable production.
The study was performed on a 1,200 hectare property
exploited for more than 20 years in Abufari County
(municipio) in the state of Amazonas. The size of harvested
areas varied from 15 to 50 hectares. The planned cutting
cycle comprised 25 years, during which an average of 20
trees were cut per year (Table 2.5).

The author observed that the gaps always included a
great majority of those species that form part of the
primary forest. During the first year after cutting, there
was a sizeable reduction in the natural regeneration
population of the 1.5 m height-5.0 cm DBH classes. The
remaining classes were affected less. Regeneration depended
basically on the remaining classes in the 1.0-1.5 m height
category, on the classes begun from seeds stored in the
soil, and on those available near the gaps.
Perturbances promoted by harvest were limited to the
areas cleared in locating the trees and to the gaps formed
by fallen trees. There was an adequate stock of species
involved in the harvest process and, with the exception of
Ocotea cymbarum, all underwent sufficient natural
regeneration (Table 2.6). An average of about seven
commercial trees remained per hectare, a good indication
that the forest under observation was responding adequately
to the management practices.

Policies for forest management. Forest management can
also be applied to mechanized commercial harvesting.
However, costs impose a serious limit. Barreto and Uhl
(1993) calculated the cost for a cutting cycle of 20 years
in Paragominas (Par& State) at US $187 per hectare. To
encourage forest management, the harvest tax should be close
to this value. However, in the case of Paragominas, every
hectare harvested but not reforested is only taxed $55, so a
policy of forest management adoption is discouraged.
In Costa Rica, Kishor and Constantino (1993) found
that, although sustainable natural forest management is a
declared national goal, it is seldom put into practice.
Instead, private landowners prefer to mine the forest or
convert it into cattle ranches or forest plantations, since
natural forest management cannot compete financially with
alternative types of land use.
To make natural forest management an attractive option
for private landowners, Kishor and Constantino (1993)
propose high rates of real price appreciation and/or
subsidies, but, based on past trends and the availability of
substitutes, this is unlikely to happen.
They also found that consumer willingness to pay for
"green-labeling" is insufficient to cover the cost of
sustainable management. According to these authors, if
environmentally sustainable forest management is chosen as
the preferred land use from a social point of view,
subsidies are necessary. However, they conclude that, from
a budgetary efficiency point of view, in a situation of high
discount rates due to macroeconomic risks, it would make
more sense to target the subsidies to small farmers, who
face lower opportunity costs from doing sustainable
management than big or corporate owners.
Besides forest management, the efficiency of processing
needs to be increased. On average, the efficiency in
traditional lumber production is about 40%, and in improved
sawmills it is about 60%, which evidences much waste in the
two production systems. An alternative way to use these by-
products would be to develop small products for specialty
markets. In 1993, the USA imported $14,686,453 in small
wooden articles from Brazil (Table 2.7).
The production and marketing of tropical timber.
Tropical wood production represents only 14% to 15% of the
total timber produced globally. Production growth rates
during the 1980s fell to 1.5 percent, in comparison with 5.6
percent between 1960 and 1980. Table 2.8 shows a sizeable
increase in industrial roundwood (logs and pulp) and
processed wood products in most regions during 1960s and
1970s, followed by a considerable decrease in production
growth during the 1980s. An exception has been the
production of wood-based panels, in particular plywood,
manufactured in Asia (Panayotis et al., 1993).
The market for tropical timber is often seen as being
responsible for the disappearance of tropical forests. But
these charges are not justified on two accounts. First,
deforestation of the tropics is mainly caused by agriculture
and cattle raising. According to FAO (1987), 60.4% of

global deforestation is caused by agricultural practices
performed for subsistence, 16.8% by permanent agricultural
practices, 8.3% by cattle raising, 5.6% by lumbering
activities, and 7.9% by the production of firewood and
charcoal. Second, timber exports, particularly of roundwood
and sawnwood, constitute only 11% of the total timber
production. In the Brazilian Amazon, from 25 million ha of
land deforested during the '70s and '80s, at least 70% were
for planting pasture for cattle raising, while the rest were
deforested as consequence of shifting agriculture and
extractive activities (mainly logging), in that order of
importance (Mahar, 1989).

would show that, in reality, the problem of deforestation
has had a negative influence on timber production in the
tropics, with regional differences of course. Table 2.8
shows a decline in the growth rate of tropical timber
production during the 1980s. This decline was caused
fundamentally by the depletion of African and Asian forests.
Africa, with one of the world's highest deforestation
estimates, lost 11% of its market share. In Asia, the
Philippines, which during the 1960s was among the principal
timber exporters, today imports timber (Panayotis et al.,
1993).
In this context, and according to statistics provided
by ITTO (1993), Latin America emerged during the last decade
with the highest increase in exports of tropical products:
from 614 million cubic meters in 1978 to 2,633 million in
1991, this was a spectacular growth of 429% in 13 years.
In spite of the fact that the Asian countries
(particularly Malaysia and Indonesia) continue to be the
main exporters of timber (80% of global exports), Asia is
also the most important importer of timber traded on world
markets, with more than 54% of the total market, the main
countries being China, Japan, and South Korea (Panayotis et
al., 1993).
The depletion of forest resources in Africa and Asia
and restrictive policies concerning the exploitation of
roundwood or sawnwood timber by some of the most important
exporters make the tropical rain forests of South America
the main areas for future production of timber.
Even though tropical America, especially Brazil,
competes in the market with many types of timber products,
as seen in Table 2.9, it has been concentrating on sawnwood
and plywood.

Montelo Moura (1994) studied the feasibility of
agroforestry systems with species of economic potential in
extractive reserves. Using linear programming, he
determined the effects on gross income of production systems
characterized by mixed subsistence crops and plantations of
rubber and Brazil nut trees (Table 2.10). He ran tests on
four scenarios: (1) the current situation, defined as the
current productive system with its traditional extractive

practices and resource availability; (2) Alternative I,
similar to the current situation, but hiring labor during
the most labor intensive months; (3) Alternative II, similar
to Alternative I, but with the option to use both
recommended technologies and credits to cover costs and
investments; and (4) Alternative III, similar to Alternative
II, but introducing plantations of rubber and Brazil nut
trees. Alternative III was further tested at four credit
levels: at 80%, 60%, 40%, and 20% of the credit needed.
After running the linear programming simulation,
Montelo Moura (1994) found that Alternative III at the 20%
credit level would be the best alternative, where a
production unit using $1,256 would achieve a gross income of
$6,415, using 1,643% more labor than in Alternative II.
Additionally, this was less risky than the other
alternatives using credit and showed the best internal rate
of return (115%). However, the problem with this
alternative is the procurement of the hired labor and the
credit. It is also not clear how the author envisions
financing the rubber and Brazil nut plantations. It is
known that the cumulative variable costs for Brazilian
plantation rubber are about $1,854 per hectare for the first
seven years (the immature period) (ITC, 1993); the figure
for Brazil nuts could be higher, since the period before
production begins is longer.

A search in the international market for products that
occur naturally or could be cultivated in the Amazon can
help identify potential species to be incorporated into
agroforestry systems. After Brazil nut, pepper (black and
white) is probably the second most important non-timber
forest product exported to the USA from the Amazon,
constituting some 30% of the $20 million total Brazilian
exports of this product between 1989 and 1993. However,
prices have been dropping recently, and this is also true of
products such as annatto and refined babassd oil. In
contrast, other products, such as herbs used for medicinal
or other purposes, have risen in quantity marketed and
maintained their prices, while others, such as fruits of the
genus Capsicum, have even increased in price (Table 2.11).
The potential international and national market for
products from selected agroforestry species for the state of
Acre has been researched by ECOTEC. The products were
selected based on the recommendations of various
institutions engaged in agroforestry research systems in the
state of Acre. They involved food products such as assai
(Euterpe sp.), cupuassG (Theobroma grandiflorum), guaran&
(Pranceara cupana), heart-of-palm (from Euterpe oleracea),
peach palm (Bactris gasipaes), and annatto (Bixa orellana);
nuts such as Brazil nut and cashew (Anacardium sp.);
commodities like rubber, coffee, cocoa, and black pepper

(Piper nigrum); oils such as copaiba and dendd (Elaeis
guineensis); and lumber.
Based on secondary information, ECOTEC (1993) evaluated
the market share, price flexibility, price stability, the
price oscillation index, and the risk coefficient of each
product. In order to establish the price stability
coefficient, the market share of each product is divided by
the income per work-day, the result of which is divided by
the price flexibility index (the inverse of price elasticity
of demand). At the same time, market potential was
evaluated by considering the change in supply according to
price at the international, national, and local levels. A
risk coefficient was also determined by dividing the income
per work-day for each product by the price flexibility index
and dividing this result by the price oscillation index
(yearly average of price oscillation). In other words, a
low risk will be the consequence of high wages, a high
flexibility index, and a low price oscillation index.
Based on its findings (Table 2.12), ECOTEC (1993)
divided the studied products into three groups: (1)
recommended products: (Brazil nut and rubber); (2) products
in need of complementary analyses assaii, cashew, cupuassu,
heart-of-palm, and lumber); and (3) products not recommended
(the commodities, copaiba oil, guarand, peach palm, and
annatto).

There are, however, two observations concerning the
ECOTEC findings. The first has to do with the way it
compares the income per work-day of the selected products.
For rubber and Brazil nuts, the value referred to income
generated from 300 hectares, while for the rest of the
products, the value referred to that generated on only one
hectare. Thus, the risk coefficient for extracted rubber
and Brazil nuts was -2.74 and -4.70, respectively, but when
income per work-day was applied to one hectare, as in the
case of the other products, the risk value was only -0.009
and -0.011 for rubber and Brazil nut, respectively.
Consequently, the initial finding of 'low risk' has to be
reversed to 'the highest risk of all studied products.' In
other words, rubber and Brazil nut are not good bets.
The second observation is related to the productivity
figures and lumber prices. ECOTEC considered a productivity
of one cubic meter of lumber per hectare of cultivated
forest and a market price of $9.05 per cubic meter.
According to other sources, these figures are too low,
making the ECOTEC results appear biased.
Creating Income-Generating Forests in the Amazon
Also of interest for conservation in the Amazon is the
creation of income-generating forests. Myers (1984)
proposed an "industrial forest" to conserve biodiversity in
the tropical biome while obtaining economic returns from the
59
forest. Clement (1993) prefers the term 'income-generating'
to 'industrial,' and he also emphasizes that this
alternative can be applied to both non-destructive
harvesting of large numbers of existing species and the
introduction of species with new uses into the standing
forest or previously degraded fragments of it. However, an
income-generating forest differs from an agroindustrial
plantation in that biodiversity is permitted or even
encouraged, while in a plantation only the economically
exploitable species are permitted.
Clement and Myers agree in the sense that only those
species with established markets or with markets that could
be developed by entrepreneurs would be harvested or planted,
but the forest could contain numerous other species with
potential for use at some point in the future. However, to
Clement, the question is how to design and create an income-
generating forest that would enhance the economic viability
and management of its sustainable use? He recommends: a)
deciding on the number of economically exploitable species
to be included while trying to expand the few species
currently used; b) the methodological selection of species
from a minimum of 100 with known uses and several thousand
with potential uses, taking into account both market
orientation and species adaptation to the local environment;
and c) the design of procedures for species introduction
into and/or management in the forest ecosystem.

Today, most extractive reserves are restricted to only
two products (rubber and Brazil nut), which is one of the
reasons for their economic fragility. Colonists and
caboclos tend to depend upon one or two 'export' crops and a
few subsistence crops. The Amerindians rarely cultivate
'export' crops, although they may be involved in rubber and
Brazil nut extraction to some extent (Clement, 1993).
Diversification of production is desirable so that, if the
market for one of several products declines drastically, the
producer still has other products on which to rely.
Another strong reason in favor of diversified forest
production is that any extractive species that develops
attractive economic prospects will immediately be put into
cultivation elsewhere and produced more cheaply there (Homma
1989). The history of modern tropical agriculture clearly
corroborates this observation. Rubber extraction was
restricted to the Amazon until its value rose to a level
that made its cultivation of interest in Southeast Asia
(Hecht and Cockburn, 1990). Quinine (Cinchona ledgeriana)
followed the same route in the late 1800s (Dominguez and
Gomez, 1990). The only way out of this dilemma consists of
finding and developing large numbers of species in a process
that continues over long periods of time. The long term
nature of this process has probably been underestimated by
those starting to work on the development of new species for
extractive purposes (Clement, 1993).
Diversification of species also has its limitations.
According to Clement (1993), these are: 1) knowledge about
the species; 2) markets; 3) labor force; and 4) capital.
Generally speaking, at the producer level, only a few
species can be successfully managed by each family. At the
community level, though, it should be possible to increase
this number.
Clement (1993) emphasizes that the selection of new
species will have to be highly site specific. He also
develops several criteria that have to be met by the new
products, which should be: (1) of high unit value, (2)
easily processed, and (3) easily stored, either before or
after processing.
Arkcoll and Clement (1989) suggested that many
Amazonian fruit crops might also have potential as new
crops. These can only be stored, however, if they are first
processed or pre-processed (cleaned and frozen, for
example). Most fruit crops meet the first criterion, but
the second and third ones can only be met after the
infrastructure for processing and storage has become
available. In other words, they will be suitable for most
areas in the Amazon only at some point in the future, when
practitioners of the income-generating forest have become
successful.
Finally, Clement (1993) discusses how to establish the
income-generating forest, taking into account whether an
area has been submitted to much, little, or no
deforestation. This is a very important aspect, especially
in view of the fact that, in the Amazon, each household has
developed its own way of taking advantage of the different
deforestation patterns.
Strategies for Enhancing Income Generation
Experiences with communities concerning strategies for
enhancing income generation from the Amazon are rare.
Perhaps the most important is the experience of Cultural
Survival Enterprises (CSE) which demonstrates that forests,
in the long run, have more value left standing than razed
for pasture or conventional agriculture. Scientific
research and subsequent economic projections suggest that
forest areas are ultimately worth more for their sustainably
harvested timber and non-timber products than when cleared
for logging and/or conversion to pasture, agriculture, or
even plantations (Clay, 1993). Since 1990, CSE has sent
about 350 different non-timber forest products (NTFPs) out
of the Brazilian Amazon for sampling by 120 companies in the
USA and Europe.
To provide a theoretical and practical strategy for
improving the marketing of NTFPs, there are eleven major
lessons CSE has learned during this period: (1) define land
and resource rights, (2) start with products already on the
market, (3) increase competitiveness, (4) diversify
production and reduce dependence on a few products, (5)
63
diversify the markets for raw and processed forest products,
(6) add value locally, (7) capture the value added to the
products as they travel farther from the forest, (8)
commercialize high volumes, (9) aim for a decent profit, not
a killing, (10) solutions must be on the same scale as the
problems, and (11) international markets are meant to
protect ecosystems, not the people who live in them (Clay,
1993).
Conclusions
The importance of extractivism based on rubber and
Brazil nut collection has tended to decrease in the Amazon.
However, extractive activities still are practiced by an
important number of the Amazon's inhabitants. These
activities are performed based on unequal, although not
necessary exploitative, production arrangements, due to the
costly and risky transport conditions and the high risks of
marketing extractive products that normally have large price
variations.
Forest extraction based only on rubber and Brazil nut
is an inefficient land use practice. This inefficiency is a
consequence of: (1) the relatively large holdings that
families must exploit, (2) the relatively low productivity
of each production unit (for example, when compared with
rubber plantations), and (3) the relatively low income
64
generated by these activities when compared with other, more
intensive, uses of resources in the Amazon.
There are, however, some alternatives for improving
extractive activities in the Amazon, which include: (1)
enriching the forest by planting economically valuable
plants and removing competitors, (2) utilizing the natural
high densities of certain tree species which are scattered
throughout the Amazon, (3) increasing the value added to
forest products before they leave the reserves, (4)
increasing the number of species which are extracted, and
(5) developing agroforestry systems. Most of these
alternatives could be part of a much more recent approach
called the income-generating forest.
Both non-timber and timber products may be harvested in
the Amazon under sustainable management. There are
experiences which show that non-timber products (such as
Brazil nut, heart-of-palm, cumaru seeds, and essential oils)
and timber products (particularly lumber), when harvested
sustainably, may generate enough income to improve the
livelihood of people living in the Amazon forest.
One of the main strategies of developing an income-
generating forest is the diversification of the productive
base. Having the possibility of marketing several products
is less risky than marketing only one. However,
diversification also has limitations, mainly related to the
lack of experience, market, labor, and capital; in
65
consequence, only a few products may be successfully managed
at the family level. Selection of these products has to be
highly site specific, and the species selected must meet
conditions such as: (1) yield high unit value products, (2)
yield an easily processable product, and (3) yield an easily
stored product.
The dilemma summarized above shows that, in spite of
the difficulties of extractive activities, they still
constitute an important land use, particularly in forest
areas where reserves have been established in the Amazon.
Since conservation is one of the major objectives of these
reserves, and land use systems involving deforestation are
not allowed in these areas, improvement of extractivism
could help reconcile the objectives of conservation and
livelihood improvement of the people living there. To
achieve this, it is necessary to perform site specific
evaluations of alternatives to improve extractive activities
in the Amazon, which constitutes the main goal of this
research.

STUDY SITE AND METHODOLOGY
Location of Study Site
The Antimari State Forest (ASF), located 80 km north of
the state's capital Rio Branco, was part of the former
Arapixi, Pacatuba, and Mapinguari rubber estates. The
forest extends over an area of 66,168 ha (FUNTAC, 1991a)
between the meridians 68000'19" and 68021'45" W, and the
parallels 09010' and 09031'S (Figure 3.1). In the flat to
lightly undulating terrain lie the settlements of 48
families (300 people), who live and work there, and another
25 families (150 people) within the area of influence. The
48 ASF families occupy a little more than one fifth of the
total reserve area. These inhabitants practice rubber
extraction and Brazil nut gathering, along with basic
subsistence agriculture, animal husbandry, fishing, and
hunting.
Since its creation in 1988, the ASF has been managed by

botany. Assessments of the timber industry in Rio Branco
have been extensive. These studies seek alternative
management plans for the ASF. However, the social
organization needed to establish conditions required for
alternative work, has not been developed in the ASF.
Socioeconomic Aspects
Colonization of the state of Acre occurred at the end
of the XIX century, when the extraction of latex from native
rubber was an important economic activity. Affected by the
rubber industry bust, rubber tappers shifted their efforts
to the collection and selling of other products, Brazil nut
being the most important. These two complementary
activities constituted the base of the state's economy for
several decades, contributing an important percentage of the
primary sector to the state's economy (FUNTAC, 1991a).
Policies for the Amazon occupation have undergone
considerable change since 1964. The post-war subsidies for
extractive activities were cancelled, while agricultural
production was given an incentive. As a consequence, the
majority of rubber estate owners were forced to sell their
lands because they had incurred so many debts. Rubber
tappers, however, remained in the area performing extractive
activities in their production units (colocag5es) (FUNTAC,
1991a).
This situation is not restricted to the ASF. Old
rubber estate owners, for example, did not even sell their
land but simply abandoned the area. One of the tasks of
FUNTAC and also of the Institute for Colonization and
Agrarian Reform (INCRA), is to make the old owners sell
their land to the state in order to establish a
comprehensive development project based on the sustainable
use of the forest resources.
The largest number of people to live in the ASF was 250
families. The census conducted by FUNTAC in 1991, found 62
families in the ASF and 32 in its surroundings. From this
group, FUNTAC interviewed 80 families (53 from the ASF, and
27 from its surroundings) totalling 441 persons (107 adults
and 334 individuals younger than 20 years). Thirty-seven
percent were males and 62.5% were females. Seventy-two
percent of the total were originally from the state of Acre.
Ninety percent of these owners of the colocagao or
"posseiros" interviewed were illiterate. Of the families
that settled in the ASF, 20 resided along the banks of the
river and 42 in the interior (FUNTAC, 1990a).
FUNTAC (1991b) found three forms of migration in the
ASF: from one colocagao to another, from one rubber estate
to another, and from the ASF to the city. Causes cited for
these migrations are low productivity of rubber trees, game
depletion, large distance from good fishing sites, absence
of Brazil nut trees, bad relations with the patron, and
relatives living too far from each other.
The socioeconomic order is three-tiered, consisting in
ascending order of the rubber tapper, the "marreteiro,"I and
the patron. The patron at the top of the social pyramid
centralizes the production of a group of colocacges and
interchanges manufactured products with the rubber tappers
based on the aviamento system. Below the rubber tapper
there may be the "meeiro." This is a rubber tapper without
a colocagao of his own who works primarily in the extraction
of rubber for another rubber tapper who owns a colocagco.
The production arrangements are ruled by the levels
described above. In the survey performed by FUNTAC there
were 18 buyers (patrons and "marreteiros"), two of whom
monopolized half the production. Although some rubber
tappers owned boats to transport their products, they
preferred selling their products to the nearest patron
instead of trying to find a better price in a place where
transactions are conducted in cash. This is largely due to
their illiteracy; they favor bartering their products for
available goods as opposed to dealing with cash
transactions. Basically, patrons and "marreteiros" purchase
only rubber and Brazil nuts from the colocagoes.

According to their economic activities, rubber tappers
can be divided into three groups: rubber and Brazil nut
collectors, collectors who also are small scale agricultural
producers, and former collectors dedicated to small scale
subsistence farming (FUNTAC, 1991b). However, at the time
of this study only one family belonged to the last group.
Families normally work alone. With the exception of
labor pooling for land clearing, there are few other family
interchanges. There is little community organization,
however, some family members are interested in establishing
this link.
Production Systems
In 1990 the total production of rubber in the ASF was
40 tons, with an average of 753 kg per colocacao. All the
rubber produced is coagulated, pressed, and sold in blocks
that average 50 to 60 kg. Approximately 17% of each
family's hand labor is involved in this task. Considering
the fact that there are 544 trails for rubber extraction
(with an average of 114 trees) of which 442 have been used,
FUNTAC (1991b) concluded that 13.6% of the existing rubber
trees are utilized.
The production of Brazil nuts in the ASF was 72 tons
(1990). In contrast to rubber trees, Brazil nut trees do
not appear homogeneously spread throughout the ASF. There
are colocagces with no Brazil nut trees, and others where
72
production is strictly for family consumption. Based on 13
colocacges, FUNTAC (1991b) estimated an average production
of 100 cans or 1300 kg per colocagao.
Taking the prices from Rio Branco ($0.60 per kilogram
rubber in block and $0.45 per kilogram unprocessed Brazil
nuts), FUNTAC (1991b) estimated an average annual gross
income of $980 per family.
Agricultural production is practiced on an average of
3.63 tarefas (0.9 hectares) per colocagao. In this area
rice with maize, beans, and manioc are planted in sequence,
for a maximum period of three or four years. The soil is
cleared by burning, leaving 1.25 hectares as secondary
succession forest per colocagao.
Nine families raised cattle in 1991, with an average of
1.88 hectares (7.5 tarefas) per colocagao and an average of
6 animals (1.25 tarefas per head). Some fruit species such
as assai, pataua, and bacaba are collected and consumed in
the area, as are the products of hunting and fishing. Men
and women spend an average of four hours each time they go
fishing, with males spending less time than females. The
use of bait and line yields about two meals per fishing
period.
The average time spent hunting is five hours per
hunting period. Hunting periods occur about 8 days per
month. The products of hunting and fishing make up 46.5% of
the food consumed: fish (15.8%), deer (Mazama spp) (13%),
73
peccary (Tajassu tajacu) (5.1%), and others. The ingestion
of protein per kilogram of body weight among those residing
in the ASF was estimated to be 0.73 g per hunting day
(FUNTAC, 1991a).
Housekeeping and child care is almost entirely a female
responsibility. There is no information from ASF, but a
study conducted in the Chico Mendes reserve showed that
these activities absorb 10% of labor demands in one
colocagco (CNS, 1992).
Fauna
Studies of wild animal densities and their diets were
performed by FUNTAC between June 1990 and April 1991. An
evaluation of the densities of 21 animal species showed most
hunted species in the ASF had lower population densities
than those in less populated Amazon areas where similar
studies have been conducted (FUNTAC, 1991c). In addition,
samples of 311 stomachs collected showed that some plant
species consumed were of commercial value (Table 3.1).
Vegetation
The ASF contains an average of 115.5 trees per hectare,
with a mean basal area of 15.23 meters per square hectare.
The volume, including the bark, is 129 cubic meters per
hectare (FUNTAC 1990). Based on the different forest types
surveyed, three management areas were defined (Table 3.2):

regions, the total volume, as well as the basal area and
abundance of species was higher than the third region (Table
3.3).
Still the volume in the third region approaches the
estimates of the other two in terms of potential wood per
tree with a DBH higher than 40 cm. Also, in terms of
exploitable volume, the volume estimated for the first
region was considerably superior to the second and third
regions.
The economic potential for wood harvest from the three
regions was based on a forest inventory and a bibliographic
survey for the species found. In this manner, 82 species
were selected by FUNTAC. The economic characterization of
these species according to the volume of trees with DBH
higher than 40 cm showed that regions 2 and 3 could produce
similar volumes, but less than region 1 (Table 3.4).

A study of costs for timber production was conducted by
FUNTAC. The study was based on a model for mechanized
commercial harvest and rotation schedules of 25 years, and
indicated that the cost of log production fluctuated between
US $28.3 and US $47.3 per cubic meter (Table 3.5). This
means that the price of the product barely covered the cost,
even if the yield had been higher than 25 cubic meters per
hectare.

volumes potentially harvested in the ASF.

A major percentage of the costs incurred stems from the
construction of access roads. For just one area of 4,000
hectares out of the six projected, the road construction
cost was more than $267,000. Additionally, the transport of
wood to the principal center of production in the ASF would
cost $3.11 per cubic meter, with the transport from there to
Rio Branco (135 km) an additional $14.06 (Table 3.6).
From these figures, FUNTAC concluded that due to the
large distance of the ASF from Rio Branco, the
commercialization of wood logs was not economically
feasible. It would be necessary to process the wood on site
and harvest a volume of 35 cubic meters per hectare if
returns were to justify the investment. In addition, in

order to reduce costs, a portable log processing plant to
allow the transport of sawn timber from the ASF to Rio
Branco would have to be installed.
To examine the potential use of other species from the
ASF's floristic composition, a botanical study was conducted
which registered 844 species (FUNTAC, 1990). Considering
their potential use by the rubber tappers, 431 species were
classified in 14 different categories (Table 3.7). However,
a characterization or efficiency test of the considered
species was not performed, with the exception of a test
conducted by the National Service for Industrial Learning
(SENAI) regarding the diversification of species used in
timber and furniture (SENAI, 1994).

Considering the necessity for (a) species
identification, technological properties determination, and
classification into categories for final use, (b) studies
about "unknown" timber types, and (c) finding substitutes
for the few species currently demanded in Rio Branco2; the
SENAI developed a project for the diversification of wood
species for timber and furniture. The aims were to find
substitutes for some of the species in high demand, and to
plan and execute programs for their market introduction.
From forest inventories conducted in the ASF, SENAI selected
20 species that offered excellent potential for both timber
and furniture use (Table 3.8).
Contrary to the ECOTEC findings (discussed in Chapter
2), a preliminary FUNTAC market analysis seeking potential
NTFPs products, revealed a market for copaiba (Copaifera
multijuga) derivatives such as soap and oil. The oil is
marketed in both bottles and capsules (FUNTAC, 1993). Some
laboratories in S&o Paulo pay up to $5 per liter oil, and
sell it to pharmacies at for $10 per liter. The pharmacies,
in turn, sell the oil in 30 mm bottles at $1.50 per unit.
In S&o Paulo approximately 2,000 liters are sold per year.
In Rio Branco (August 1993) copaiba oil was sold at $0.75
per liter. Also, different copaiba soaps are sold for $2.50
per unit.
2 Only 3 species in the furniture sector and about 9 in the timber
sector comprise about 90% of Acre's timber industries, causing a rapid
depletion of their tree sources.
