All these activities have a great impact on the world’s water reserves and in particular on its limited resources of fresh water. As the world economy becomes more and more globalised and integrated in order to meet the demands of an ever increasing population, water consumption increases accordingly, placing pressure on the drinking water supply. In “water poor” nations, competition increases between people and commercial activity over dwindling supplies of potable water – water is diverted toward irrigation for expanded food production, to upmarket hotels and golf courses to cater to rising numbers of wealthy tourists, and to new industries to provide the consumer products demanded by the global market. But the impact is not only on the increased volume of water used. Expanded agricultural activity not only consumes more water but also pollutes remaining water supplies with the run-off of chemical fertilisers, while large scale irrigation schemes can destroy natural water ecosystems; greater industrial consumption of water creates greater amounts of waste water that can overwhelm sewage and water purification plants; rapidly expanding populations in water stressed countries place overwhelming pressure on water delivery systems. | All these activities have a great impact on the world’s water reserves and in particular on its limited resources of fresh water.

In terms of water stress levels, it is generally considered that countries with annual supplies of 1,000-2,000 m3 per person are water-stressed, with 1,000 m3 thought to be the minimum per capita requirement of a moderately developed country.<ref name="Mohsen" /> Societies with less than 500 m3 per capita are said to suffer from absolute scarcity | In terms of water stress levels, it is generally considered that countries with annual supplies of 1,000-2,000 m3 per person are water-stressed, with 1,000 m3 thought to be the minimum per capita requirement of a moderately developed country.<ref name="Mohsen" /> Societies with less than 500 m3 per capita are said to suffer from absolute scarcity, so this "lack of water then requires application of expensive technologies and becomes a constraint on food production, social and economic development, and protection of natural systems.”<ref name="Mohsen" /> | ||
