Jonathan Muriuki presented on evergreen agriculture in East Africa. He discussed how conventional farming is not sustainable and leads to soil degradation. Conservation agriculture with trees (CAWT) and evergreen agriculture were presented as alternatives that maintain soil cover year-round. Evergreen agriculture integrates trees with annual crops to create a double-story system. Examples of evergreen agriculture systems in East Africa were provided. Key components needed for successful scaling up were identified as germplasm, characterization of systems, knowledge management approaches, and enabling policies and extension networks.
