In this study the vulnerability of water resources to environmental change is assessed on a river/lake/groundwater basin scale for the Southern, Eastern, Western & Northern African Regions.

Groundwater pollution is a serious problem throughout the African continent. While this is not surprising, very little attention has been paid to the problem. Information on this threat to Africa's future is therefore not readily available.

This report presents the GIWA assessment of the Humboldt Current region, located along western South America, stretching from the Ecuadorian-Colombian border to the south of Chile.

In Africa, most rivers, freshwater lakes, and aquifers are shared by two or more countries. The diversity of politial, social, and economic structures and organizations among African countries and the varied temporal preciptation and distribution of water on the continent make hydropolitical setting very complex and prone to vulnerability.

This report presents the GIWA assessment of the Mekong River region which comprises parts of Cambodia, China, Lao PDR, Myanmar, Thailand and Vietnam.

This report presents the results of the GIWA assessment of the Oyashio Current region – one of the most productive waters in East Asia.

This report presents the results of the GIWA assessment of the Sea of Okhotsk region. Rapid population growth and economic development have led to increasing pollution loads in the Amur River basin – the region’s largest drainage basin – placing increasing pressure on its diverse ecosystems.

Seamounts, deep-sea corals and fisheries - an ubiquitous ocean floor feature, a key marine ecosystem, and an important human activity: together they have created one of the most critical ocean issues. The report reveals the global scale of the vulnerability of habitat-forming stony corals on seamounts, and that of associated marine biodiversity and assemblages, to the impacts of trawling, especially in areas beyond national jurisdiction.

The GEO Yearbook 2006 is the third annual survey of the changing global environment produced by UNEP, in collaboration with many world experts in environment research and action. The Yearbook includes global and regional overviews.
