They make a respectable income on land previously exploited by slash and burn clearing for cattle and monocultures (single crop plantings). Their income is based upon reforestation of degraded rainforest areas using succesional agroforestry systems that employ up to seventy different plant species which generate income over a short, mid and long term horizon. These farms are vertically stratified, employing under story and canopy species that form a surrogate rainforest structure that locks carbon like a true rainforest and is useful in preserving the region's unique biodiversity. And how did they learn these techniques? Through tough experience, and by observing their indigenous neighbors. History The Colony The first attempts at black pepper cultivation in the colony started in 1947 and by the 1950's, there was an acceleration of planting in the form of huge monoculture tracts paired with cattle ranching. By 1956, production from Tomé-Açu met all of the Brazilian demand. The 1960's saw further expansion of black pepper production as the Brazilian farmers in the region began to take up its cultivation. By the 1970's, crops began to feel the effect of Fusarium, a fungal disease which shortens the productive life of the black pepper plant from 15 to 5 years. It spread through the region's crops. The farmers reacted by clearing more land and planting more black pepper in order to keep production at the same level—and even increased production. In the 1970's Brazil began to export black pepper and, by the early 1980's, was the world's largest producer and exporter. During this same period, however, world prices for black pepper began to fall dramatically - Southeast Asia had come back into pepper production creating a market surplus. In Brazil, the market surplus coupled with high internal inflation and reduced farm credit availability halted large scale expansion, and pepper production shifted to small family farms. In Tomé-Açu these family farms began a small farming revolution. The Tomé-Açu farmers had witnessed the fallacy of large scale monoculture. With no farm credit available there was no money to purchase fertilizer or other agricultural inputs. At the same time they began to understand that the fertility of the rainforest is held by the trees not the soil, so any sustainable agriculture in this region would need to have tree crops as its base. These small growers lived in close contact with the indigenous people of the region, who lived by a combination of subsistence farming and extraction of natural products from the forest. Learning from their neighbors, the Japanese immigrants developed a diverse and productive system of agroforestry that proved both sustainable and capable of generating middle class incomes to family farmers—something that exists no where else in the Amazon. CAMTA (Cooperativa Agrícola Mista de Tomé-Açu ) Cacao Sustainability – The Tomé-Açu Model As the Tomé-Açu farmers began experimenting with systems of agroforestry or land originally cleared for black pepper monoculture, they also realized that a key component of sustainable agriculture in the tropics is diversity. A forest has a canopy and an under story. If they could plant productive species that occupy both levels then they would have a balanced system that could provide year-round income that was sustainable over a long period of time. Two species were considered pivotal to the development of productive agroforestry systems: cacao and cupuaçu. Both are shade tolerant species, native to the Amazon basin, that begin to produce three to five years after planting and continue to produce indefinitely. Both species produce large quantities of leaf litter and are beneficial in the recuperation of degraded soils and both can be grown at fairly high densities beneath income generating canopy species such as Brazil nut, teak, mahogany, andiroba, paricá and feijó. The marketable product from cacao is the bean, a commodity traded on international markets and subject to price fluctuations that are uncontrollable at the local level. With it there is potential for large profits or corresponding losses depending on the international market price. With cupuaçu there is some market for the seeds, but it is the pulp, consumed primarily by the domestic market, that generates most of the income. The two products complement each other like an investment strategy that incorporates elements of both high and low risk. Another native crop that has recently become important in the Tomé-Açu agroforestry system is açaí. Açaí is a multi-stem palm species that occurs naturally on the floodplains of the Eastern Amazon. It produces large bunches of small blackish-blue fruit that can be processed into a thick juice that is nutritious and extremely high in antioxidants. After manioc flour it is the highest source of caloric intake by the rural population of the region. Its high fat content and incredible antioxidant activity have recently attracted the attention of health food and energy drink producers around the globe. Açaí stalks also provide the heart of palm (called palmito) that is used in salads, soups and empanadas around Brazil. Even better, the stems of the plant regenerates easily after cutting. The agroforestry models using multiple species crop with staggered yields empower small farmers in the Amazon to derive significant income from their holdings using environmentally sound techniques. One indication of the economic success achieved by these farmers is that only 18% of them grow staple crops such as rice, beans, corn and vegetables on their properties. The remainder purchase these at the market. Over 36% of the farmers market products 12 months of the year and 63.6% can market products more than eight months per year. Though most farms have 3 to 4 staggered yield crops, what is unique about the Tomé-Açu farmers is their willingness to experiment. One farmer in the region, Naburo Sakaguchi, has 73 species growing on a 60 hectare farm. This may be extreme, but several farmers utilize more than ten species to generate income from a single agroforestry system. Although no studies have been made to evaluate the impact that these farms have had on the region's biodiversity, there is significant research showing that shade grown coffee and cacao in much simpler agroforestry systems are capable of maintaining a significant amount of bird, small mammal, reptile, amphibian and insect biodiversity. The combinations of canopy and under story species provide a structure similar to the natural rainforest and observers walking in some of the more complex farms above have commented that they appear almost indistinguishable from the natural rainforest. A number of authors have suggested that, in addition to preserving their own significant portion of a region's biodiversity, these types of farms can also serve as buffer zones around remnant tracts of original rainforest, effectively limiting human impact and serving as corridors for species movement (and gene flow) between remnant tracts of rainforest. Conclusion and Summary An important component of this success has been the foresight and vision of CAMTA, the farmers' cooperative, in developing markets for the indigenous fruits grown by its members. The affluence these farmers enjoy today would have been impossible without construction of the fruit pulp processing plant in the 1980's and the access to additional markets that it provided. The Tomé-Açu farmers have also had access to rural credit, a key component when investing in new crops and techniques. These farmers have taken a holistic approach to agriculture using the rainforest itself as their model and have created sustainable agroforestry systems that provide income from diverse sources. Cacao is a key component of many of these systems, but nowhere does it dominate. The farmers who grow cacao are buffered against fluctuations in world cocoa prices by other crops that generate equal or greater income. Their initiatives are homegrown and unsupported by or dependent upon foundations or NGO's. The agroforestry systems that they have developed are world famous among ecologists and economists. Many consider this a model for reforestation of rainforests around the world. Estimates differ among scientists, but it is generally accepted that more than 20% of the Amazon has already been deforested. The principal causes of this deforestation have been clearing for cattle and soybean bean cultivation, timber harvesting to make charcoal and predatory logging. Much of this land has already been abandoned because the nutrients in the soil have been exhausted. It now lies fallow, covered by second growth capoeira. The ranchers, farmers and loggers have moved on and the deforestation continues. It can be argued that if the agroforestry techniques employed by the Tomé-Açu farmers were used to develop this land in the first place, most of the land cleared in the last 20 years would now be entering it's most productive period, generating 10 times or more the income per hectare possible from cattle. This is hindsight, but it can be foresight. Eighty percent of the world's largest rainforest and most precious reserve of biodiversity still remains, and although most of it will eventually be developed, perhaps the farmers of Tomé-Açu have shown us how. |
