Environmental effects

An environmental flow is the water regime provided within a river, wetland or coastal zone to maintain ecosystems and their benefits where there are competing water uses and where flows are regulated. Pioneering efforts in South Africa, Australia and the United States have shown that the process to establish them poses great challenges.

The population of western gray whales numbers only about 100 animals and is classified on IUCN's Red List as "critically endangered".

L’Afrique de l’Ouest est l’une des régions du monde les plus vulnérables au changement climatique. L’impact souvent désastreux de la variabilité et des extrêmes climatiques au cours des trente dernières années en est une parfaite illustration, mais aussi un des signes avant-coureurs de cette vulnérabilité.

West African is among the most vulnerable regions to climate change worldwide. The often disastrous impact variability and extreme events over the past thirty years is a striking illustration and a harbinger of this vulnerability.

The deep ocean is increasingly recognized as a major global reservoir of the Earth's biodiversity, although but a small fraction of the oceans' ecosystems found at depths below 200 meters have been studied. This report presents findings on the current extent, location and value of high seas bottom trawl fisheries worldwide and the countries involved.
