Increasing availability of water over space

Improving the availability of water over space is one of the technical measures to increase the resilience of WASH systems, as more points of water in an area means better access for people and livestock.

Different options are:

• Local recharge, retention/storage and re-use of water, which are increasingly being seen as the most important adaptations for ensuring water availability and food security to rural and urban populations, especially in developing countries in the face of climate change.

• Various methods for gaining more water from rainwater and groundwater sources, some of which are innovative and need further research.

• Methods on how to limit impact on existing saline groundwater and how to recharge/dilute it.

• Methods to increase available water to communities through treatment of non-potable saline water.

• Ways to improve handpump sustainability since this affects water availability in many areas.
