  Safe Use of Wastewater in Agriculture

  The Food and Agriculture Organization of the United Nations (FAO) together with the World Health Organization (WHO), the United Nations Environment Programme (UNEP), the United Nations University Institute for Water, Environment and Health (UNU-INWEH) and the UN-Water Decade Programme on Capacity Development (UNW-DPC), in collaboration with the International Commission on Irrigation and Drainage (ICID) and the International Water Management Institute (IWMI), have initiated a Capacity Development Project on the Safe Use of Wastewater in Agriculture. The project was launched in November 2011 with an international workshop in Bonn, and will run until May 2013.

  The impetus behind the project is population growth and rapid urbanization which are intensifying pressure on fresh water resources. The high level of local water demand is leading to increasing water scarcity and stress and is consequently driving the use of nonconventional waters, such as (treated) urban wastewater.
