AB: Agricultural land use changes have been quite dramatic in the last few decades in the Indo-Gangetic plains as an outcome of many factors including the green revolution. But, there are wide-spread disparities in the agricultural land use practices and its intensification, in addition to the economic outcome of these sub-regions within the Gangetic basin as one moves from the west to the east. In addition to the geo-physical and ecological differences, this can be attributed to a mix of demographic, social, economic, and political and policy differences. Water use within the agricultural system is widely influenced by these human factors. An integrated framework has been proposed by the authors for identifying and quantifying the linkages between land use and water use in this coupled human-environment system. The research being carried out here will discuss the framework with reference to the analysis of the changes in the agricultural system in the past five decades within the Indo-Gangetic plains, with links to the water use, and the ecological, economical and social indicators of change within the coupled system context. Based on the experiences of the authors in developing agent based land use (AGENT-LUC) models at the regional and national scales, this integrated framework will also form the basis for the agent based modelling approach. It is estimated that the model proposed would help understand the competition and allocation of water needs of the different land use regimes (for eg. agricultural vs. urban water use) and help evaluate sustainable management strategies within the basin.
