英文摘要

Climate change will affect the availability, quality and quantity of water needed for basic human needs, thus undermining enjoyment of the basic rights to safe drinking water and sanitation for billions of people, warns the latest UN World Water Development Report. The authors call on States to make more concrete commitments to address the challenge.

An estimated 2.2 billion people currently do not have access to safely managed drinking water, and 4.2 billion, or 55% of the world’s population, are without safely managed sanitation.

Water use has increased sixfold over the past century and is rising by about 1% a year. However, it is estimated that climate change, along with the increasing frequency and intensity of extreme events – storms, floods and droughts, will aggravate the situation in countries already currently experiencing ‘water stress’ and generate similar problems in areas that have not been severely affected. Furthermore, the report highlights the fact that poor water management tends to exacerbate the impacts of climate change, not only on water resources but on society as a whole.

The United Nations World Water Development Report is a UN-Water flagship report that focuses on a different water and sanitation theme each year. The report is published by UNESCO, on behalf of UN-Water, of which WMO is a member.
