In summary, the challenges related to the water sector include having too much water, having too little of it and dealing with polluted water. A significant proportion of the world's population already lives in areas subject to high or very high water stress, caused by an imbalance between available water resources and water use. Climate change is likely to exacerbate the current issues faced by the water sector, in various ways, but it is not the only underlying cause. Water sector policy and decision makers should include climate-related considerations as an important element for the sustainability of intervention strategies while also integrating other sources of pressure in their analysis.
