RWH SYNTHESIS PAPER

This synthesis paper discusses the significance of rainwater harvesting (RWH) as a crucial technique for addressing climate-induced risks in smallholder farming within the Limpopo Basin. It explores existing RWH technologies and practices, evaluates their effectiveness, and proposes new approaches to enhance resilience. Furthermore, gaps in current methodologies are identified, along with recommendations for future improvements. The research emphasizes the need for comprehensive solutions to support farmers in adapting to climatic challenges.
