Abstract
Prosper Global and Practical Action have been supporting communities in the flood-prone plains of Western Nepal to design and construct bio-dykes – a low-cost, nature-based approach that prevents riverbank slumping and degradation and reduces the risk of floods for riverine communities and farmland. Bio-dykes are constructed using locally available materials such as soil, sandbags, bamboo, and deep mesh-rooted vegetation. Bio-dykes require less technical expertise than traditional concrete flood control structures and can be built and maintained by community members.
