Land-use change, primarily through tropical forest loss and degradation, is estimated to contribute between 6–17% of all anthropogenic greenhouse gas emissions (van der Werf et al. 2009). The maintenance and enhancement of natural carbon stocks are therefore considered key climate change mitigation measures, especially through the developing mechanism on Reducing Emissions from Deforestation and forest Degradation, forest conservation, sustainable management of forests and enhancement of forest carbon stocks (REDD+).
Well-planned and carefully implemented REDD+ actions can have positive outcomes that are additional to emissions reductions. Such ‘co‐benefits’ include biodiversity conservation and maintenance of ecosystem services, as well as direct improvements to livelihoods and the rights and well-being of local people.
Spatial 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.
