Biodrainage relies on vegetation, rather than mechanical means, to remove excess water. It is economically attractive because it require only an initial investment for planting the vegetation, and when established, the system could produce economic returns by means of fodder, wood or fibre harvested. This publication is a compilation of existing information, both formally published and unpublished literature. It aims to inform water professionals in general and drainage experts in particular of current knowledge of biodrainage and further research need.
