It is a fact that water use is today rising at double the rate of global population growth owing to urbanization, more water-intensive agricultural products, growing industrialization of emerging markets and the impact of climate change. The supply of fresh water is relatively static; hence, the rapid rate of demand growth is, not surprisingly, causing some stress.
An estimated 1/3 of the world’s population currently lives in water-stressed or water-scarce countries. On the current trajectory, it is estimated based on most recent population projections (according to the Food and Agriculture Organization of the United Nations and the Geneva Conference) that by 2025 countries will have water demand in excess of supply and 64% of the world’s population will be under significant pressure.
The Middle East (and North Africa) has the greatest absolute and relative water supply problem, in fact classified as ‘high’ stress compared to the rest of the world which is classified as moderate (Asia) and low (all other regions).
