This document is the starting point for the construction of the Brazilian Assessment on Biodiversity and Ecosystem Services. During 2016, the document was prepared by the BPBES team and discussed with different sectors of society (NGOs, government, private sector). The contributions presented are an instrument for consultation and dialogue with different social and economic actors who, in their activities, directly or indirectly affect or are affected by biodiversity and associated ecosystem services. The dialogue will improve the Assessment once it can contemplate the different aspects that constitute quality of life and human well-being in Brazil. In addition, it will project its reach beyond the academic universe in order to become a scientific support for decision making at both the national and subnational levels.
