This has been a generic first attempt that can be fine-tuned and customised for each type of ecosystem and each kind of service value. Ecosystem services are defined by the Millennium Ecosystem Assessment as ‘the benefits people obtain from ecosystems'.
Mountains occupy 24% of the global land surface area and are home to 12% of the world’s population. Mountains have an ecological, aesthetic, and socioeconomic significance, not only for those living in the mountain areas, but also for people living beyond them. However, the importance of ecosystem services arising from mountains is not properly recognised. The HKH region is endowed with a rich variety of gene pools and species, and ecosystems of global importance. It is a storehouse of biological diversity and a priority region in many global conservation agendas. The region has many unique ecosystems that play a critical role in protecting the environment and in providing livelihoods for much of Asia and beyond.
The Hindu Kush-Himalayan region has had very few resources to develop a detail scientific understanding needed to assess climatological, environmental, and other data in the past and there is very little information upon which a baseline for comparison with the present can be formed and future impacts can be anticipated.
