Identification of Pilot Sites that Are Required to Implement Climate Change Adaptation Measures Based on Best Practices and Available Technologies and Spatial Data in Four Different Provinces of Mongolia

United Nations Development Programme, Mongolia

Criteria have been identified for site selection for climate change adaptation measures, such as catchment reforestation and natural spring protection. The criteria used were physical and biophysical parameters that could be determined from climate change model results and satellite data. These include air temperature, total precipitation, surface temperature, evaporation, vegetation (NDVI), and net primary product (NPP). The fifth major global reanalysis (ERA5) produced by the European Centre for Medium-Range Weather Forecasts (ECMWF), 30*30-kilometer grid data and 250-meter data from the Terra satellite were used. Using the above sources, air temperature, precipitation, vegetation, surface temperature, the long-term average of the net primary product, and evaporation, deviations, and their sigma changes were calculated in Zavkhan, Khovd, Dornod, and Sukhbaatar provinces of Mongolia. The -1, -2, and -3 sigma formulations of the main indicators over the long-term averages were calculated, and their frequency was calculated for each sigma. It aims to determine how many years the -1, -2, and -3 sigma changes will be counted over the 22 years from 2000 to 2021. There are three categories of indicators for catchment reforestation and rehabilitation: unnecessary, necessary, and essential. Each indicator was evaluated for the catchment reforestation area. As a result of the evaluation of 10 selected locations in Khovd province based on 15 criteria, a percentage score was given to each site. According to the results, the sites in 10 selected locations in Khovd province scored between 53.6% and 71.6%. The criteria for determining the location of the natural spring protection are also divided into three categories: unnecessary, necessary, and essential. Each indicator was evaluated for the group. As a result of evaluating 6 locations of selected natural springs in Khovd province on 16 criteria, the percentage of necessity was given. According to the results, 6 selected sites in Khovd province scored between 49.2% and 79.6%. The results of the analysis suggest that the above criteria can be used to determine the location of the climate change adaptation sites.
