By creating bunds and dykes on the edges of hydropower reservoirs, water can be retained in the draw down period to create artificial wetlands and fisheries, mitigating some potential negative impacts of hydropower development.
There are valuable resources trapped in city waste, including nutrients for soils, water for irrigation, and energy for household use. By creating business models for recovering and reusing these resources, we can help pave the way for reduced pollution and more sustainable food and energy systems.
This sourcebook details how to best implement integrated water resource management at the community level in East Africa by building resilience, sustaining landscapes, managing water, conserving soils, and addressing learning and complexity.
Over the last ten years, researchers from IWMI have identified a number of options for safe resource recovery from Fecal Sludge. The options provide the stages and technical solutions available for safe recycling of Fecal Sludge and its by-products, mainly in agriculture.
These options provide an overview of some low-cost wastewater treatment technologies for pathogen removal, which can be adapted for use in urban and peri-urban areas in low-income countries where the wastewater is of domestic origin
