IUCN

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.

Amphibian populations are disappearing from habitats all around the world. The crisis caught us by surprise - and only now are we able to fully grasp the scope of the situation. Around a third of amphibian species are threatened with extinction - mass extinctions of this magnitude have not been seen since the time of the dinosaurs. The crisis shows us that the world has changed.

The Cross River gorilla (Gorilla gorilla diehli) is recognized by IUCN as Critically Endangered, and is the most threatened taxon of ape in Africa. Work during the last two decades has revealed that fewer than 300 Cross River gorillas may remain, spread across an area of about 12,000 km2. The outlook for these apes is far from hopeless, but a concerted and sustained effort will be required if their long-term survival is to be assured.

Central America is a region that shares ecosystems, river basins, and protected areas. The development of projects, plans or activities likely to produce transboundary impacts need to be appropriately considered, and an EIA process established and anchored in regional policies and legislation. This book, analyses the relevant initiatives on transboundary EIA in the world, and advances the basic elements of a regional agreement on EIA in a transboundary context for Central America.

El Centro de Derecho Ambiental y la Oficina Regional de UICN para Mesoamérica presentan el libro Gobernanza de aguas compartarget_idas: aspectos jurídicos e institucionales, el cual es un esfuerzo conjunto que recoge los aportes del diálogo sobre gobernanza de cuencas compartarget_idas celebrado en Ciudad de Guatemala en septiembre de 2004 y organizado por la Unidad de gestión del agua de la UICN-Mesoamérica.

Re-introduction is one tool for conserving great apes and their natural habitats. These guidelines adapt other IUCN documents to pertain specifically to the re-introduction of great apes.
