Experiences from the Ground

The opportunities and challenges that come with the reuse of wastewater in agriculture often are case specific. Therefore, this session focuses on reuse experiences from the ground. In an interactive way, this session brings together government agencies, private and civil actors around examples of wastewater reuse.

Achieving food security (SDG 2) is of high priority, increasingly threatened by water scarcity and climate change impacts. The safe reuse of wastewater could play an important role towards increasing agricultural production. A key motivation for increasing wastewater reuse in agriculture is reduced costs, since this waste contains nutrients useful as agricultural fertilizer, along with enough water to irrigate part of all the irrigated farmland in the world. Wastewater reuse also reduces nutrient leaching to lakes, rivers, and groundwater. But how do we harness these opportunities and tap into this largely unused resource from a planning, policy, livelihoods and financial point of view? And what are the pitfalls that should be avoided to ensure safe and sustainable wastewater reuse?

The objective of the seminar is to discuss opportunities and limits for the safe reuse of wastewater and in agriculture.
