Terms of reference for the third priority medium term project, the livelihood-based Watershed Management – Taking to Scale for a basin-wide Impact, prepared from the BAS Multi-Purpose Water Resources Development Study. This project will support the identification of small-scale local-level livelihood-based watershed management projects with an emphasis on the development of sustainable multisectoral opportunities followed by the design and implementation of a programme to take the approach to scale. The rationale is that, when taken to scale, such small-scale local interventions represent real basin-wide solutions to some of the key environmental and socio-economic challenges such as high levels of sediment transport, ecosystems degradation and deforestation, lack of food security and poor access to electricity.
