Accelerating soil erosion of Tanzania’s agropastoral landscapes and associated impacts on water quality forms an existential threat for food, water, and livelihood security. This project will address the lack of capacity in gully erosion and water quality monitoring and restoration in the region. Working in the Lake Manyara catchment, this project will demonstrate a novel monitoring-to-management approach for improving our understanding of gully erosion and facilitate community-led land and water restoration actions. The project will build local capacity and set-up scientific monitoring programs to quantify water, soil, and nutrient losses from gullies. Laboratory capacity will be developed in nutrient and metal analysis so that NM-AIST can grow into an independent centre of expertise for gully and water quality monitoring and consultancy. In parallel, local stakeholders will be supported to restore problematic gullies and evaluate their success using locally available techniques.
