This synthesis focuses on estimates of biodiversity change as projected for the 21st century by models or extrapolations based on experiments and observed trends. The term “biodiversity” is used in a broad sense as it is defined in the Convention on Biological Diversity to mean the abundance and distributions of and interactions between genotypes, species, communities, ecosystems and biomes. This synthesis pays particular attention to the interactions between biodiversity and ecosystem services and to critical “tipping points” that could lead to large, rapid and potentially irreversible changes. Comparisons between models are used to estimate the range of projections and to identify sources of uncertainty. Experiments and observed trends are used to check the plausibility of these projections. In addition we have identified possible actions at the local, national and international levels that can be taken to conserve biodiversity. We have called on a wide range of scientists to participate in this synthesis, with the objective to provide decision makers with messages that reflect the consensus of the scientific community and that will aid in the development of policy and management strategies that are ambitious, forward looking and proactive.
Resource Type: ReportsThe Convention on Biological Diversity has established a global target for the protection of 10% of each of the world’s ecological regions by 2010. This report uses the WWF Terrestrial Ecoregions of the World and the 2009 version of the World Database of Protected Areas to analyse progress towards achieving this politically established conservation goal across the world.
Resource Type: ReportsTechnical report on the collection of geographic data, the regression analysis of explanatory factors of land use patterns, the development of a set of three alternative scenarios, and the modelling of land use changes using the CLUES model. This work was carried out as part of the ICRAN-MAR project's sub-result 1.2, "Trends in land use integrated with spatial, hydrological and oceanographic models for use in modelling".
Resource Type: ReportsSouth East Asia contains nearly 100,000 km2 of coral reefs, almost 34% of the world total. With over 600 of the almost 800 reef-building coral species, these reefs have the highest levels of marine biodiversity on earth. Heavy reliance on marine resources across South East Asia has resulted in the overexploitation and degradation of many coral reefs. An estimated 88% of them are threatened by human activity.
Resource Type: ReportsSubstantial amounts of detailed biodiversity data exist for the world, and these data can be used to guide conservation priorities. WCMC compiled key data in order to identify areas of high species richness and endemism. This book is made available by kind permission of the UK Department for International Development for whom it was prepared.

Coral reefs are an integral part of the Caribbean fabric, threading along thousands of kilometres of coastline. Unfortunately, these valuable ecosystems are degrading rapidly under the mounting pressure of many human activities. Understanding the nature and extent of these threats and their likely economic impacts on the future productivity of Caribbean coral reefs is of central importance to conservation and planning efforts.
The Reefs at Risk in the Carribean project was launched to help protect and restore these valuable, threatened ecosystems by providing decision-makers and the public with information and tools to manage coastal habitats more effectively.
