Track 2-07: Climate Change Impacts on Grassland Production, Composition, Distribution and Adaptation
Description
The main objective of this study is to estimate pasture biomass changes in Mongolia using the simulation model CENTURY. For the study framework we used the fenced pasture biomass data from 1960’s to 2008, over 60 meteorological stations and simulation data of the carbon, nitrogen, aboveground and belowground biomass, potential evapotranspiration, evaporation, transpiration and precipitation data across these grasslands. The simulated climatic and other parameters were estimated meteorological station based and their differences between 2 time periods were calculated. With purpose to make comparison of the present situation to the future situation used Climate Change Scenarios under A2, A1B and B1 emission scenarios by HadCM3 Climate Model for 2020, 2050 and 2080. For the present situation all parameters were long term averages from 1960s to 2008 and the future change estimation used Climate Change scenario A1B and statistical values separately by different ecosystems over following natural zones such as, high mountain, forest steppe, steppe and desert zones.
