Adaptive water harvesting innovations have become crucial for ensuring food security in the Southern Ethiopian Highlands, facing challenges such as erratic rainfall and soil degradation. A systematic review of existing literature from peer-reviewed journals and grey literature sources focusing on recent studies conducted between and. Evidence suggests that the adoption rate of rainwater harvesting systems has increased by a factor of 1. 5 in the last decade, particularly among smallholder farmers who have seen an average yield increase of 20%. The reviewed technologies demonstrate significant potential for improving water availability and crop yields in the Ethiopian Highlands, though further research is needed to identify optimal configurations tailored to local conditions. Investment in infrastructure development, farmer education programmes, and policy support are recommended to maximise the benefits of adaptive water harvesting systems.
