Water politics rising to top of global agenda

Paul Gillespie in the Irish Times: The politics of water will loom large in international affairs this century. This is emerging under the influence of climate change, unequal access to water between richer and poorer peoples, intensifying agricultural and industrial use and transboundary conflicts.

Looking at world politics through the lens of water provides many insights on these issues. According to statistics provided for the annual World Water Week conference in Stockholm last month, 97 per cent of the Earth’s supply is salt water and, of the remaining 3 per cent, some 70 per cent is frozen in the polar icecaps.

The other 30 per cent is mostly present as soil moisture or stored in underground aquifers, so less than 1 per cent of the world’s fresh water is readily accessible for direct human use. This is clearly a precious resource, essential to life and capable of being wasted or used creatively to improve the human condition. At present 70 per cent is used in agriculture, 20 per cent in industry and 10 per cent domestically.

The impact of human-induced climate change and global warming is evident from statistics showing that the number of great inland flood catastrophes was twice as large per decade between 1996 and 2005 as between 1950 and 1980, and economic losses were five times as great.

Almost two billion people were affected by natural disasters in the last decade of the 20th century, 86 per cent of them by floods and droughts. By 2030, 47 per cent of the world’s population will be living in areas of water stress. The number of climate refugees could reach 330 million this century if current warming trends are not reversed….
