Cette étude examine les coûts de conservation et la valeur des avantages liés à la biodiversité pour la zone couverte par le projet QIT Madagascar Minerals (QMM) et ses alentours, mettant particulièrement l'accent sur le complexe forestier de Tsitongambarika (TGK).

Este estudio analiza los costos de la conservación y el valor de los beneficios asociados con la biodiversidad en y alrededor del área del proyecto QIT Madagascar Minerals (QMM), con especial atención al bosque Tsitongambarika (TGK). El objetivo es cuantificar y valorar los cambios en los servicios ambientales resultantes de las intervenciones que se apartan de lo acostumbrado en TGK, es decir, la deforestación y degradación ambiental, a favor de alguna forma de conservación forestal.

This study examines the costs of conservation and the value of benefits associated with biodiversity around the QIT Madagascar Minerals (QMM) project area, with a focus on the Tsitongambarika (TGK) forest complex. The aim is to quantify and value changes in ecosystem services resulting from interventions that deviate from 'business as usual' in TGK, i.e. projected continued deforestation and ecosystem degradation, in favour of some form of forest conservation.

There are two principles here, both reflecting the natural world. The first is that natural systems are based on cycles, for example water, nitrogen and carbon. Secondly, there is very little waste in natural systems.

The entry into force of the International Treaty on Plant Genetic Resources for Food and Agriculture marks the commitment of the world community to a freestanding convention directed at addressing both global needs for food security and internationally agreed objectives regarding the concepts of 'access and benefit-sharing' found in the Convention on Biological Diversity.

In 2009, IUCN-Oceania Regional Office in partnership with SOPAC and SPC established the Pacific Resource and Environmental Economics Network (PREEN). The PREEN was established in response to a need by the small but growing group of practitioners in the Pacific for a professional body to share information and access peer support to conduct natural resource and/or environmental economics in the region.

Ce document présente les expériences de six barrages construits en Afrique de l'Ouest entre la fin des années 1970 et la fin des années 1990 : Sélingué au Mali, Niandouba et Confluent au Sénégal, Moussodougou, Bagré et Kompienga au Burkina Faso. Des études rétrospectives ont été réalisées pour chacun d'eux et leurs conclusions ont été discutées lors d'ateliers nationaux multi-acteurs dans chacun des pays concernés.

This document examines the experiences of six dams built in West Africa between the late 1970s and late 1990s: the Niandouba and Confluent in Senegal, the Sélingué in Mali, and the Bagré, Kompienga and Moussodougou dams in Burkina Faso. Retrospective studies were conducted for each of these dams and their conclusions discussed in multi-stakeholder national workshops in each country.

Currently there is a deficit of information on the impacts of invasive alien species (IAS) within the community, key sector groups and governments of these countries. Most often, the problem is not recognised until the invasion becomes noticeable nor has ecological, economic or social consequences.

Esta publicación de la Lista Roja resume los resultados de los mamíferos terrestres mediterráneos, al tiempo que ofrece la primera visión general del estado de conservación de estas especies para cumplir las directrices de catalogación regional de la Lista Roja de la UICN. Identifica así las especies que están amenazadas de extinción a nivel regional a fin de que se puedan realizar las acciones de conservación apropiadas para mejorar su estado.
