Training resource book on a participatory method for modelling bioresource flows

This guidebook helps researchers and extensionists learn an easy rapid appraisal technique that enables farmers to draw conceptual models of their farm systems. The drawings help researchers and extensionists to understand quickly local agricultural practices and identify entry points for integrating new enterprises into the farm. The book can be used independently or to accompany two videos, Aquaculture and the Rural African Farmer and Pictorial Modelling: A Farmer-Participatory Method for Modelling Bioresource Flows in Farming Systems.
