Table 3. A summary of the mapped farm management practices clustered according to the ecosystem service with which they interact. The final column lists references that investigated the potential impact of these practices. Bold = practices identified in both Roslagen, Sweden, and the Mbulu highlands, Tanzania. Normal = practices found only in Roslagen, Sweden. Italics = practices found only in the Mbulu highlands, Tanzania
