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 acai - the latter is the least known, but the one with the most potential and fastest growing markets. Here we map the socioecology of acai 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 acai (prices, costs and net revenues) for an area of 164,000 km(2). 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 acai 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.
