Farmer-led documentation: learning from Prolinnova experiences is the fourth in a series of booklets that collects experiences of Prolinnova partners from diverse countries in promoting participatory agricultural research and development in ways that enhance local innovation capacities. It captures the experiences of network partners in giving farmers a key role in documenting their own experiences and innovations. It starts with a short introduction to farmer-led documentation (FLD) and summarises how the approach has been developed within the network thus far. More details on hands-on implementation of FLD are described in the five cases based on pilot activities undertaken in Burkina Faso, Ethiopia, Niger, South Africa and Sudan. The booklet concludes with some key lessons drawn from these experiences and highlights some points for consideration in pursuing the FLD approach.
