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: ReportsA 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: ReportsThis reports looks at the carbon storage function of protected areas as a contribution to the development of strategies for reducing emissions from land use change. In particular, it is relevant to the current discussions surrounding reducing emissions from deforestation and forest degradation (REDD) under the UN Framework Convention on Climate Change (UNFCCC).
Resource Type: ReportsThis study combines the best available data on carbon stocks and deforestation with protected area data to estimate the area of forest loss within the protected area network of the humid tropical forest biome during 2000-2005.
Resource Type: ReportsWell-planned and carefully implemented REDD+ actions can have positive outcomes that are additional to emissions reductions. Such ‘cobenefits’ include conservation of biodiversity and maintenance of ecosystem services. Potential cobenefits from REDD+ are highly relevant in Nigeria, where services provided by forests make an important contribution to the livelihoods of local communities (Aruofor 2001).
Spatial analyses relating potential co-benefits to carbon stocks can support planning and decisionmaking on REDD+. Simple mapping tools can be used to help identify areas where high carbon, high biodiversity priority, and ecosystem service values overlap, and show how these relate to pressures and management options. This brochure presents results from some initial spatial analyses for Nigeria.
Resource Type: ReportsThe 24 page demonstration atlas, launched at the 14th Conference of the Parties to the United Nations Framework Convention on Climate Change, shows that areas high in both carbon and biodiversity do exist and can be identified by relatively simple mapping tools. Prioritising such areas could give the 'double benefit' of reducing emissions from land use change whilst conserving biodiversity. Three regional maps along with six national maps are shown for the tropics, derived from global-scale data.
Resource Type: ReportsSpatial analyses relating to co-benefits can provide key information to support planning and decision-making on REDD+ at national and sub-national scales. To do so, they should be based on data developed at an appropriate scale and should address those benefits and challenges deemed most important by key stakeholders and practitioners.
This report presents results from an initial effort to produce such analyses for Cambodia. It includes new data on the distribution of terrestrial carbon stocks in Cambodia and analyses of its relation to areas of importance for biodiversity, Protected Areas and other land management units, and pressures (such as forest cover loss). It is expected that the study will be developed further in collaboration with other institutes and stakeholders.
Resource Type: ReportsCo‐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: ReportsAt UNFCCC COP14 UNEP-WCMC released Carbon and biodiversity: a demonstration atlas (Kapos et al. 2008). Using global datasets on carbon storage in terrestrial ecosystems and areas of high priority for biodiversity conservation, this publication illustrated the potential of spatial analyses to assist decision-makers in identifying areas where reducing emissions from land use change could at the same time help to secure biodiversity benefits.
However, to support planning and decision-making at national and sub-national scales, such analyses must be based on data developed at an appropriate scale and should be done in consultation with a wide range of stakeholders to help prioritise among the different benefits and services under consideration.
This report presents data and analyses on areas of high carbon density and high priority for biodiversity in Jiangxi Province, China. The degree of their overlap with protected areas is assessed, and their relationship to the distribution of human population is explored.
