The present paper revisits the AESR concept to revise this map with the help of georeferenced soil information system (GeoSIS) recently developed at the sub-country levels of the Black Soil Region (BSR) and the Indo-Gangetic Plains (IGP). GeoSIS has been proved to be an excellent tool in successful application of Agro- Ecological Sub Regions (AESRs) at the regional and national levels. This novel approach could narrow the knowledge gap in revising the soil and agro-management technologies, used in dry land agriculture for productivity enhancement with special reference to the BSR dominated by cotton and soybean cropping systems. For the IGP, similar approach was used for the rice-wheat cropping systems. Revised AESR map identifies the areas under different level of productivity of these four important crops of two major food-growing regions of the country. The identified areas in the form of thematic maps shall help the planners and land resource managers to prioritize areas for resource management. %K Agro-Ecological Sub-Regions, AESRs, Georeferenced soil information system, Black Soil Region, Indo-Gangetic Plains, Land Resource Manager, Resource Management, GeoSIS, IGP, BSR, Cropping Systems
