Riverside communities experience many deficiencies in electricity supply and basic sanitation. Regarding forest products management there is a dependency of açaí and limited use of other species. Thus, the project located at Ilha das Cinzas – Pará state, aims to: evaluate agroforestry systems with ‘pau mulato’ and other arboreal and agricultural species; generate actual technical indices to the management of native açaí grooves through its mapping and monitoring along with participating families; Analyze the flooded forest timber production chain and the efficiency of local sawmills; Quantify the residual biomass (açaí stones, Calycophyllum spruceanum and other sawdusts) for generating electricity and scale a system to run a family unity sawmill; To test sewage treatment systems. The project will be divided in two phases. The first will select entrepreneurial dwellers sensible able to carry on adaptive research after receiving training in issues related to alternative energy, sanitation, and the diversification of productive systems. On the second phase, after selecting the best techniques, the project will expand to reach 50 families. The practice for managing native açaí grooves will be the one recommended by Embrapa Amapá, which maintains forest diversity. As the project outcomes, it is expected that energy from solar and residual biomass be validated for the region; That a type of sewage treatment including gravity filter and a septic tank be adopted; And to foster the multiple use of native forest resources.
