Potential impacts of climate change on the environmental services of humid tropical alpine regions.
Climate change will displace ecosystem boundaries and strongly reduce the total area of tropical alpine regions. Drier and warmer soil conditions will cause a faster organic carbon turnover, decreasing the below-ground organic carbon storage. Since most of the organic carbon is currently stored in the soils, it is unlikely that an increase in above-ground biomass will be able to offset soil carbon loss at an ecosystem level. Therefore a net release of carbon to the atmosphere is expected. Changes in precipitation patterns, increased evapotranspiration and alterations of the soil properties will have a major impact on water supply. The magnitude and even the trend of most of these effects depend strongly on local climatic, hydrological and ecological conditions. Under conditions of climate change, a new natural soil organic carbon equilibrium will be reached.
