The Global Biodiversity Assessment provides an independent, critical, peer-reviewed scientific analysis of the current issues, theories and views regarding the main global aspects of biodiversity. Assesses the current state of knowledge, identifies gaps in understanding and draws attention to those issues where scientists have reached a consensus as well as those where uncertainty has led to conflicting viewpoints and a need for further research. Describes and analyses the main components of current research, including the characterization, origins, dynamics, distribution, monitoring and multiple values of biodiversity; biodiversity and ecosystem functioning; human influences on biodiversity; biotechnology; data and information management, and communication. Around 1500 biological and social scientists from around the world have contributed their knowledge and expertise to the Assessment, providing an unprecedented source of information for decision-makers, officials, scientists and any others interested in the future of our planet. The Global Biodiversity Assessment was commissioned by the United Nations Environment Programme (UNEP) and funded by the Global Environment Facility (GEF).
