Concept
WASH
Summary
WASH (or Watsan, WaSH) is an acronym that stands for "water, sanitation and hygiene". It is used widely by non-governmental organizations and aid agencies in developing countries. The purposes of providing access to WASH services include achieving public health gains, improving human dignity in the case of sanitation, implementing the human right to water and sanitation, reducing the burden of collecting drinking water for women, reducing risks of violence against women, improving education and health outcomes at schools and health facilities, and reducing water pollution. Access to WASH services is also an important component of water security. Universal, affordable and sustainable access to WASH is a key issue within international development and is the focus of the first two targets of Sustainable Development Goal 6 (SDG 6). Targets 6.1 and 6.2 aim at equitable and accessible water and sanitation for all. In 2017, it was estimated that 2.3 billion people live without basic sanitation facilities and 844 million people live without access to safe and clean drinking water.
The WASH-attributable burden of disease and injuries has been studied in depth. Typical diseases and conditions associated with lack of WASH include diarrhea, malnutrition and stunting, in addition to neglected tropical diseases. Lack of WASH poses additional health risks for women, for example during pregnancy, or in connection with menstrual hygiene management. Lack of sanitation contributes to about 700,000 child deaths every year due to diarrhea, mainly in developing countries. Chronic diarrhea can have long-term negative effects on children, in terms of both physical and cognitive development. Still, collecting precise scientific evidence regarding health outcomes that result from improved access to WASH is difficult due to a range of complicating factors. Scholars suggest a need for longer-term studies of technology efficacy, greater analysis of sanitation interventions, and studies of combined effects from multiple interventions in order to better analyze WASH health outcomes.
