Mapping the socio-ecology of Non Timber Forest Products (NTFP) extraction in the Brazilian Amazon: The case of açaí (Euterpe precatoria Mart) in Acre
Highlights We estimate an annual production of açaí in Acre as of 850 thousand tonnes. Açaí contributes to 17% of the household rents. Well-established extractivists shift to cattle ranching even inside sustainable use reserves.
Abstract Non-Timber Forest Products (NTFPs) contribute to the livelihoods of more than 6 million households in the Brazilian Amazon. Of the three most important NTFPs in the Brazilian Amazon – rubber, Brazil nut, and açaí – the latter is the least known, but the one with the most potential and fastest growing markets. Here we map the socioecology of açaí extractive systems in the Western Amazon state of Acre, Brazil. We interviewed 49 extractivists in settlements and in the emblematic Extractivist Reserve Chico Mendes (RCM) to model ecology (tree density, productivity) and production chain of açaí (prices, costs and net revenues) for an area of 164,000 km2. We estimate a potential annual production of 850 thousand tons for the entire Acre State, which could generate net revenues of US$ 71 million/yr. This is well above the average production of 136 thousand tonnes (over the last 25 years). Net revenues average US$ 57 ha−1.yr−1, with açaí contributing, on average, to 17% of the annual household income. In two case studies, we found a diversity of livelihoods comprising agriculture, NTFP collection, and livestock rearing that were grouped in two broad types of extractivist livelihoods: “old” and “new” settlers. Our results suggest that old settlers tend to focus on cattle ranching as their main economic activity, even inside extractive reserves (RESEX). The shift from extractivist activities to cattle ranching undermines the conservation role of this type of protected area. We conclude that without significant financial support in the forms of subsidies and other development programs NTFPs will continue to struggle against the economics of cattle ranching.
