Co‐benefits, often called multiple benefits, are the positive impacts of Reducing Emissions from Deforestation and Forest Degradation (REDD) that are additional to emissions reductions. These include ecosystem and social benefits such as biodiversity and non‐timber forest products. Potential co‐benefits from REDD are widely relevant in Tanzania, where forests and woodlands support the livelihoods of 87% of the rural poor (Milledge et al. 2007). Conserving biodiversity also promotes the continued provision of these benefits under environmental change (Campbell et al. 2009), thus increasing resilience to climate change. Depending on where REDD action is taken, the co‐benefits delivered will vary. Simple mapping tools can help identify how carbon, other services and pressures such as fire are distributed and relate to each other.
Here, we map the distribution of carbon stocks in relation to the possible co‐benefits of REDD, alongside other relevant factors. A new map of carbon in Tanzania’s ecosystems has been produced for this analysis.Resource Type: Reports
This study assesses the global trade in coral in an ecological and economic context. Throughout the report emphasis is placed on the trade in live coral for aquaria because the last decade has seen an enormous increase in this business. The taxonomic composition of the trade is identified and the quantities of coral passing between nations illustrate the links between major exporters and importers. Subsequent chapters present data on the practicalities of monitoring international trade in coral at the global scale. Size and growth rate data are used to assess the sustainability of the trade in live coral, and export and retail prices are used to estimate the revenue to exporting nations.Resource Type: Reports
UNEP-WCMC has provided technical support to the Secretariat of the Convention on Biological Diversity (CBD) to conduct a major study of more than 300 scientific literatures to synthesise the observed and predicted impacts of ocean acidification on marine biodiversity. The study, Scientific Synthesis of the Impacts of Ocean Acidification on Marine Biodiversity, describes an alarming picture of possible ecological scenarios and adverse impacts of ocean acidification for marine ecosystems, and highlights the direct link between climate change, ocean health and human well-being. The study was released by the CBD on the 14th December 2009 to mark Oceans Day and inform the climate change negotiations in Copenhagen.Resource Type: Reports
This report has gathered lessons that have been learned since these events that will be relevant to future management of the coasts in the context of severe weather events and other potential consequences of global warming. More than ever it is essential to consider the full value of ecosystem services - that is the benefits that people derive from ecosystems - when making decisions about coastal development.Resource Type: Reports
This report provides a synthesis of the current state of knowledge regarding the natural capital of water related ecosystems and habitats, and offers an overview of the innovative approaches that can support the analysis of the links between interconnected ecosystems. It analyses the linkages across coastal ecosystems (seagrasses, mangroves, and coral reefs) and the ‘value added’ in terms of ecosystem services (benefits) provided by these linkages as opposed to the services provided by just one system studied in isolation. The linkages between ecosystems are examined under consideration of environmental, economic, management and social aspects and recommendations are provided for integrating this new paradigm into cross-sectoral environmental practices.Resource Type: Reports
A UN-REDD workshop on ‘Identifying and promoting ecosystem co-benefits from REDD+’ was held from 27th-29th April 2010 in Cambridge, UK, convened by UNEP-WCMC. Forty-four people participated in the workshop, including representatives from five UN-REDD pilot countries, one observer country, and a number of different institutions, agencies and NGOs.Resource Type: Reports
Since 1997, UNEP has produced Global Environment Outlook (GEO) reports providing assessments of the interactions between environment and society. With its core mandate of “keeping the global environment under review,” UNEP coordinated a series of scientific assessments that included extensive consultations and participatory processes, resulting in the production of GEO reports in 1997, 1999 and 2002.
GEO-4 provides an overview of global social and economic trends, and the state-and-trends of the global and regional environments over the past two decades, as well as the human dimensions of these changes. It highlights the interlinkages as well as the challenges of environmental change and opportunities that the environment provides for human wellbeing. It provides an outlook for the future, and policy options to address present and emerging environmental issues.
It places sustainable development at the core of the assessment, particularly on issues dealing with intra- and intergenerational equity. The analyses include the need and usefulness of valuation of environmental goods and services, and the role of such services in enhancing development and human well-being, and minimizing human vulnerability to environmental change
This report presents a country profile for 19 countries of West and Central Africa, considering the status, distribution, biodiversity, uses, threats and drivers of change for their mangroves. Although there is considerable work being undertaken to research this habitat at the national, regional and global level, there are still significant gaps in information, emphasizing a need for continued efforts to improve assessment in the region. This report concludes that there has been a decline in mangrove cover in the region over the last quarter of a century, and that there will be consequences as a result of this decline.Resource Type: Reports
