The social-ecological system of the Lake Manyara basin (Northern Tanzania), a UNESCO Biosphere reserve (BR) suffers from socio-economic and environmental problems due to decreasing water levels, erosion and land and water use conflicts. An integrated assessment of the social-ecological interactions of the area is required to support future sustainable management. Within the Drivers-Pressures-State-Impact-Response (DPSIR) framework an integrated literature review and several methods of knowledge collection were combined to identify future management priorities and challenges. Annex 1 provides original fragments of information found in the selected literature, and coded as COD1, both for problems and causes of problems and for solutions. Focus groups with farmers and pastoralists collected a comprehensive set of statements about the situation. Annex 2 provides maps drawn by members of the authorities, the scientists, the pastoralists and the smallholder farmers in a community mapping exercise. Annex 3 provides a list of the 26 ecosystem services assessed by the participants during Focus Group 2. Annex 4 provides the questions used in the key informants interviews. Annex 5 provides the initial codes (letters) and corresponding merged codes (numbers) from key informants interviews. Annex 6 provides benchmarking results from the literature review and key-informants interviews
