The significant part of Mongolian economy is pastoral agriculture, which is a traditional scope of activity and main source of income for the rural population. Study of the natural vegetation dynamics is of essential interest both for decision-makers and herdsmen. During the last decades, Mongolia has suffered from prolonged droughts in combination with extensive grazing in many areas. This situation requires frequent monitoring environmental conditions and the state of pastures. This is an important and challenging security task for Mongolia since weather station network is limited for effective special monitoring and providing services and advises to decision-makers and herdsmen. During 1985–2004, the NOAA-AVHRR Global Vegetation Index (GVI) data set and its Vegetation Health (VH) products have been studied and used for analysis of pastoral changes in Mongolia. This paper discusses application of VH for early drought detection (one of the leading environmental disasters), monitoring drought impacts on pasture conditions and estimation of biomass production.
