In California, wastewater is sanitized and blended with groundwater, supporting large-scale crop production.

Exploring the use of wastewater in agriculture

Once seen as a problem to be disposed of, municipal liquid waste is now being eyed as an option for addressing water scarcity

With food demand and water scarcity on the uptick, it’s time to stop treating wastewater like garbage and instead manage it as a resource that can be used to grow crops and help address water scarcity in agriculture.

Properly managed, wastewater can be used safely to support crop production ā€” directly through irrigation or indirectly by recharging aquifers ā€” but doing so requires diligent management of health risks through adequate treatment or appropriate use.

How countries are approaching this challenge and the latest trends in the use of wastewater in agriculture production will be the focus of discussions by a group of experts taking place today in Berlin during the annual Global Forum for Food and Agriculture (19-21 January). The event has been convened by FAO along with the United Nations University, Institute for Water, Environment and Health (UNU-INWEH), the UN’s Educational, Scientific and Cultural Organization and the Leibniz Research Alliance Food and Nutrition.
