Organisation: Wageningen University, Water Resources Management. Summary: Small-scale irrigation (SSI) considered a key strategy for developing countries to maintain food security. However, they are under performing or abandoned. Excessive sedimentation and inadequate maintenance is the major causes of underperformance. This study considered four SSI schemes in Ethiopia, which differ in sediment-loads (light to heavily sedimented) and functionality (traditional and modern, fully functional and abandoned). Both a qualitative and quantitative approach was used to analyse four specific research questions.
