Participatory rural appraisalfor diagnostic analysisof spate irrigation systems

The aim of this research was to develop a participatory diagnostic analysis for a traditional non-modernised spate irrigation system in Raya Valley, in order to involve and empower local farmers within the development process, and to build a solid knowledge basis for effective improvements. A diagnostic analysis of the Harosha spate irrigation system was undertaken through the use of Participatory Rural Appraisal (PRA). Techniques focusing on spatial, temporal, socio-economical and spatiotemporal aspects of the system were performed together with the local population in order to identify and rank main problems and constraints to development. Farmers recognised the need of more resistant diversion structures and gabion walls for the stabilisation of the river bank. The involvement of farmers also helped to highlight that not only irrigation-related problems, but also flood-related problems threaten agricultural production and rural livelihoods. Rather than an irrigation system approach, a river system approach is then suggested for framing future development strategies.
