Water is becoming ‘a geopolitical issue’, says UNESCO. 2.3 billion people still live without access to drinking water.

Between 60 and 65% of all jobs on the planet, including 80% of jobs in developing countries, depend directly on water. 10% of forced population displacements in the world are directly linked to problems of access to water, according to the UN.. Nearly half of the world's population faces severe shortages for at least part of the year. When water becomes scarce, it can become a source of conflict.
