Nepalâ€™s natural habitats and the ecosystem services theyservices provide Ecosystem
How much do we know about ecosystem services in Nepal? It has been estimated that Nepal stores 485 million metric tonnes of carbon (in living biomass, FAO 2006), equivalent to almost 50% of the EUâ€™s greenhouse gas emissions in 2009, thereby contributing to global climate change regulation. There are now on-line tools that can illustrate this spatially, showing that not all areas are equally important for all services, with carbon storage in the Terai and High Himalaya (where fewer trees occur) being relatively low compared to that of the Siwalik, Middle and High Mountains.

Similarly, it is possible to illustrate water flows spatially, showing that some areas, such as the central region of Nepal, are very important for providing water to surrounding areas (including the Kathmandu Valley.

As well as general analyses, there have been a number of more specific projects in Nepal that deal with ecosystem services. Some relate to opportunities for developing or piloting Payment for Ecosystem Service schemes (PES, see p.9), such as carbon credit projects taking advantage of emerging markets for forest carbon (e.g. by the Asia Network for Sustainable Agriculture and Bioresources, ANSAB). Others relate specifically to mountain habitats (e.g. by the International Centre for Integrated Mountain Development, ICIMOD) or wetlands (e.g. by the Conservation and Sustainable Use of Wetlands in Nepal project, CSUWN).
