Impact of drought on WASH systems

Uncertainty with climate change is a big factor in accurately planning and preparing for WASH resilience. But planning only on changes in rainfall would be too simplistic, as water ''availability'' is not solely affected by climate change – population growth and changing water demand also contribute. Supply-side strategies (water volumes and availabilities) therefore need to be planned together with demand-side strategies (population growth, projected increases in demand). Lastly, greater rainfall intensity events may require some structures to be reduced (e.g. embankments, bunds) rather than increased.

Regions, experiencing less water moisture than normal, cover quite a wide area. The world map to the right (with blue background) from the [[File:DroughtMap.jpg|Global Risk Data Platform]] shows the regions with droughts recorded between 1979 and 2008, where drought events are identified as three consecutive months with less than 50% of precipitation as compared with the average.
