Adopting a shared Vision of Wastewater Management

UNSGAB calls on Country Governments at UNCSD2012 to commit to strengthen their respective actions on pollution of freshwater by human activities by recognizing the linkages between wastewater, food and energy to ensure wastewater is used as a vital resource for development; adopting a shared vision of the ways to manage urban, industrial and agricultural wastewater including collection, treatment and reuse; taking steps to agree on targets related to wastewater management; and requesting the United Nations Environmental Program (UNEP) or another UN agency to collect national statistics on wastewater management and report on its global progress

The world’s rapid transition to urbanization contributes greatly to the pressure on water, food security, and energy, as the World Water Week Workshop on Securing Water and Food in an Urbanising World explored. We cannot simply look at urbanization as an urban problem. As Pay Drechsel from the International Water Management Institute stressed in the seminar, urbanization has strong links to rural and peri-urban areas, as urban centers become sinks for both rural-borne water and nutrients. The informal sector around many rapidly developing cities, such as Chennai, has entered into a highly lucrative business pumping tanks and aquifers dry and selling the water to cities. The water is transported by trucks, adding energy costs to cities’ water supply. Through this system, informal water markets supply cities with every drop of water they can get, quickly drying up peri-urban areas. While it requires significant infrastructure costs to redirect water sources from increasing distances towards cities, peri-urban areas are suffering as cities squeeze them dry of water resources.
