The Project “Knowledge building and systematization of experiences on the valuation and payment of ecosystem services within a family farming context in Amazônia (ASEAM)” is based on the results obtained during workshops promoted by Embrapa in Brazilian Northern states. During the workshops’ sessions, local players requested thematic trainings focused on quantifying and valuing ecosystem services (SEs). Thus, the Project intends to broadcast information and train people on economic valuation of SEs, fostering knowledge interchange among different audiences, such as farmers, farming community leaders, managers and technicians, all of it based on local experiences identified during the workshops. It also intends to structure a social network for knowledge and experience exchange between targeted audiences and specialists, and to foster programs and projects focused on payment for environmental services, thus further contributing to environmental preservation. Case studies shall be carried out at watersheds located in the Amazônia biome. The data obtained in these studies will be processed using the InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs) software, in order to quantify and calculate the economic value of SEs. The project’s results will be presented to and discussed with the social network’s audiences. This action is part of the Amazon Integrated Project, which is sponsored by the Amazon Fund and administered by the Brazilian Development Bank (BNDES) in cooperation with the Brazilian Ministry of Environment.
