In Mongolia’s rural administrative system, an aimag is a province, a soum is its district, and a bagh is the smallest unit within a soum, covering households and herder communities. Across 13 soums in Uvurkhangai, Dornogovi, Sukhbaatar and Tuv aimags, open grazing, weak coordination and limited land-use information contributed to pasture degradation. The Sustainable Land Management for Combating Desertification Project formed herder groups and co-management committees, introducing participatory planning, GIS mapping, rotational grazing, field monitoring and locally managed funds. Herders submitted pasture-use proposals at bagh meetings and helped implement annual soum plans. Seasonal grazing restrictions covered over 900,000 ha, while three plots in each target soum compared grazed and ungrazed vegetation. It established 109 herder groups, linked community knowledge with local government decisions, and created a replicable model for restoring and sustainably managing dry rangelands while supporting pastoral livelihoods.
