Almost half of the world's population will live under conditions of water stress by 2030 if effective policies are not introduced and implemented; and by 2050, East Asia will require 70 per cent more water for irrigation than today to feed its growing population. Water-related environmental changes, challenges and opportunities are just some of the important issues examined in this annual report from the United Nations Environment Programme (UNEP). Others include the effects of degradation on the world's ecosystems, the impacts of climate change, environmentally related conflicts and disasters, and the unsustainable use of resources.

In the chapter on ecosystem management, the book investigates concerns about how healthy ecosystems can be maintained in the face of population pressure and climate change. "It will be impossible to meet the planet's nutritional demands without seriously reforming agricultural, land, and ecosystem management practices," the authors write. "Food production relies on the capacity of ecosystems to provide water, soils, climate regulation, and other benefits. The loss of these benefits, coinciding with increasing biofuel production in several parts of the world, could reduce the amount of land available for food crops."

Presenting recent science and environmental developments, this concise and colourful book will be of interest to anyone interested in the environment.
