Degradation of the world’s natural resources by humans is rapidly outpacing the planet’s ability to absorb the damage, meaning the rate of deterioration is increasing globally, the most comprehensive environmental study ever undertaken by the UN has found.

The study, which involved 1,203 scientists, hundreds of scientific institutions and more than 160 governments brought together by the UN Environment Programme (UNEP), concludes that without radical action the level of prosperity that millions of people in the developed world count on will be impossible to maintain or extend to poorer countries.

Water scarcity is the scourge of some of the poorest regions on Earth, the study found, leaving developing countries increasingly unable to feed themselves, and causing hardship for millions of people. There appears little prospect of this dire situation being remedied, according to the UN, without radical action being taken.

Water sources are under increasing threat from population growth, climate change, rapid urbanisation, rising levels of consumption, and the degradation of lands that previously provided a natural replenishment of water resources.

The study is intended as an aid to the world’s efforts to combat climate change and other environmental threats, as it highlights the difficulties of improving the lives of people in developing countries and tackling global warming, while food resources come under continuing pressure.

UNEP found the rate of damage to the natural environment was increasing globally, despite concerted efforts to persuade governments to take measures to improve the condition of vital natural resources, such as water, land and the seas.

“If current trends continue, and the world fails to enact solutions that improve patterns of production and consumption, if we fail to use natural resources sustainably, then the state of the world’s environment will continue to decline,” warned Achim Steiner, executive director of UNEP.

He said the tools for improving the environment for millions of people existed in developed countries but were in danger of not being used.

The study, using decades of scientific data, found that basic measures to tackle some of the key causes of environmental damage were still not being taken. These included measures to reduce air pollution, such as changes to vehicles; the damage to marine eco-systems, which can have a huge effect on fish stocks on which hundreds of millions of people depend; and the degradation of land whenmodern agricultural methods were pursued without regard to the longer-term consequences.
