Coastal and freshwater ecosystems are deteriorating in many areas and at a faster rate than any other ecosystem. Such changes are caused by intertwined factors, making it difficult to identify the problems early on. While progress in integrating these various factors in managing water and ecosystems has been made in some places, the majority of the world and its inhabitants increasingly suffers from a lack of priority given to environmental protection.Resource Type: Reports
The World's oceans play a crucial role for life on the planet. Healthy seas and the services they provide are key to the future development of mankind. Our seas are highly dynamic, structured and complex systems. The seafloor consists of vast shelves and plains with huge mountains, canyons and trenches which dwarf similar structures on land. Ocean currents transport water masses many times larger than all rivers on Earth combined.
In this report, the locations of the most productive fishing grounds in the World - from shallow, coastal waters to the deep and high seas - are compared to projected scenarios of climate change, ocean acidification, coral bleaching, intensity of fisheries, land-based pollution, increase of invasive species infestations and growth in coastal development.Resource Type: Reports
This report documents and analyses good practice examples of ecosystem-based approaches to climate change mitigation and adaptation in Europe. Case studies on ecosystem-based approaches to mitigation involved peatland restoration or conservation (11 projects) and forest conservation, restoration and reforestation (2 projects). Case studies on ecosystem-based approaches to adaptation were divided into inland waters (28 projects), coastal zone (10 projects), agriculture and forestry (11 projects) and cities (9 projects).Resource Type: Reports
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
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
The third edition of Global Biodiversity Outlook (GBO-3) summarizes the latest data on status and trends of biodiversity and draws conclusions for the future strategy of the Convention. GBO-3 is based on a range of information sources, including National Reports, biodiversity indicators information, scientific literature, and a study assessing biodiversity scenarios for the future.Resource Type: Reports
This report presents a synthesis and integration of the findings concerning biodiversity contained in the reports of the four Millennium Assessment Working Groups (Condition and Trends, Scenarios, Responses, and Sub-global Assessments).Resource Type: Reports
A new, systematic review of the evidence on the effectiveness of ecosystem-based approaches to adaptation (EbA) has been carried out to review the effectiveness of EbA and highlight the knowledge gaps. This research was undertaken as a collaboration between BirdLife International, UNEP-WCMC, IIED and the University of Cambridge.
Ecosystem-based approaches to adaptation (EbA) integrate the use of biodiversity and ecosystem services into an overall strategy for helping people adapt to climate change. To date, however, insight into these approaches has often been based on anecdotal case studies of local people’s use of ecosystems. Although they are informative, they can provide rather limited insight in terms of measuring and evaluating the effectiveness of EbA, especially compared with technical or structural adaptation measures. A new, systematic review of EbA evidence has been carried out to interrogate the scientific literature and review studies from around the world, from many different ecosystems and adopting a wide range of adaptation approaches utilising ecosystems. We conclude that EbA approaches are effective and deserve greater policy attention and political support to reach their full potential.Resource Type: Reports
