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: Reports
The Critical Site Network (CSN) Tool is a new online resource for the conservation of 294 species of waterbirds and the important sites upon which they depend in Africa and Western Eurasia. Leading global conservation organisations working for the protection of waterbirds and their habitats have joined forces to develop this tool, strengthening the implementation of the African-Eurasian Migratory Waterbird Agreement (AEWA) and the Ramsar Convention on Wetlands.Resource Type: Tools / Applications
UNEP-WCMC has been providing technical support to the work of the Convention on Biological Diversity (CBD) on biodiversity and climate change. We carried out three reviews of the recent scientific literature and these fed into the deliberations of the CBD’s Second Ad Hoc Technical Expert Group (AHTEG) on Biodiversity and Climate Change. These reviews, entitled Links between Biodiversity and Climate change: Impacts, Adaptation and Mitigation, have now been published as no 42 of the CBD Technical Series. This publication complements the main report from the CBD AHTEG which appears as CBD Technical Series No. 41 Connecting Biodiversity and Climate Change Mitigation and Adaptation.Resource Type: Reports
This paper reviews the potential for carbon sequestration in dryland ecosystems, which includes forests, but also covers other habitats, such as grasslands, and, importantly, soils. It also considers ways in which carbon storage in drylands affects land degradation issues.Resource Type: Reports
This document provides a basis for estimating the probable impacts of different forest cover creation approaches on the ecosystem-derived benefits of biodiversity, water provision, soil conservation and non-timber forest products.Resource Type: Reports
This report is a contribution to the UN’s International Year of Biodiversity and is a complement to the UNEP-hosted Economics of Ecosystems and Biodiversity (TEEB) which is bringing visibility to the wealth of the world’s natural capital. It documents over 30 successful case studies referencing thousands of restoration projects ranging from deserts and rainforests to rivers and coasts. The report confirms that restoration is not only possible but can prove highly proftable in terms of public savings; returns and the broad objectives of overcoming poverty and achieving sustainability. It also provides important recommendations on how to avoid pitfalls and how to minimize risks to ensure successful restoration.Resource Type: Reports
This collaborative project, sponsored by the Global Environment Facility (GEF) and others, developed biodiversity indicators to support planning and decision-making at the national level in four participating countries. In each country national partners developed and tested several indicators for a single focal ecosystem, using an iterative process of consultation, inventory and synthesis of existing data.
The BINU project has launched this 20-page booklet on its experience and lessons learned in developing biodiversity indicators for national use.Resource Type: Reports
How do bioenergy policies relate to the REDD+ mechanism, is the subject of this new Bioenergy Issue Paper jointly authored by UNEP and UNEP-WCMC.
The potential contribution of bioenergy in reducing global emissions of greenhouse gases has been widely debated, both in terms of climate change mitigation potential and potential risk of increases in greenhouse gas emissions resulting from land use change. This has raised the question of how bioenergy policies relate to the REDD+ mechanism developed under the UNFCCC. This issue paper examines the complexity of this relationship and stresses the importance of ensuring policy coherence across the relevant sectors.
