This report attempts to introduce a prototype scoring system for the ecological status of rivers in India and illustrate it through the applications in several major river basins. This system forms part of the desktop environmental flow assessment and is based on a number of indicators reflecting ecological condition and sensitivity of a river. The unique aspect of this study is that it interprets, for the first time, the existing ecological information for Indian rivers in the context of environmental flow assessment. The report targets government departments, research institutions and NGOs which are engaged in environmental flow management and associated policy development, and suggests some subsequent steps in environmental flow work in India.

The concept of water productivity (WP) or ‘more crop per drop’ has been revived recently in international water debates. Its application has notably been extended from single crops to mixed farming systems, integrating both crops and livestock, with the wider objective of reducing poverty. Using evidence from the Ganga Basin, India, we discuss the relevance of this concept as a tool to guide interventions for livelihood improvement and poverty alleviation. We argue that WP studies would benefit from greater attention to the role of capitals, inequities and institutions. Firstly, it is crucial to acknowledge the heterogeneity of capitals and capabilities of farmers to make changes in their farming systems and practices and avoid one-fix-all interventions. Identifying pre-existing inequities in water access within and among communities will support better targeting of poor communities. WP interventions can either reinforce or reduce inter-household inequities within communities. We stress the need for assessment of institutional impacts of WP interventions on water access and development.

In the Ganga basin in North India, water shortages are a common issue faced by farmers, even in irrigated areas. Most households in the region rely on farming systems combining crop cultivation and livestock activities. Access to and control over water supply is thus critical not only for agricultural productivity and food security but also for the production of sufficient and high quality feed for animals. Because the water requirements of animals have often been neglected or largely underestimated, scientists have recently explored the scope for increasing the water use efficiency of livestock through improved feed, animal and water management. However, there has been little research on the institutional framework required for these interventions to result not only in enhanced productivity but also in poverty alleviation and reduced inequalities. This paper addresses this gap by investigating the multi-scale and multi-sectoral institutional challenges linked with livestock water productivity interventions in North India. Three major issues are discussed: equitable access and control over water, democratic decentralisation for locally-grounded interventions, and a coordinated and integrated frame for government action. Based on observations and findings from nine case study villages across three districts of the Ganga Basin, a series of recommendations are proposed for policy-makers at district and national level.

Subsurface movement of water within the alluvial formations of Ganga Basin System of North and East India, extending over an area of 1 million km2 , was simulated using Visual MODFLOW based transient numerical model. The study incorporates historical groundwater developments as recorded by various concerned agencies and also accommodates the role of some of the major tributaries of River Ganga as geo-hydrological boundaries. Geo-stratigraphic structures, along with corresponding hydrological parameters, were obtained from Central Groundwater Board, India, and used in the study which was carried out over a time horizon of 4.5 years. The model parameters were fine tuned for calibration using Parameter Estimation (PEST) simulations. Analyses of the stream aquifer interaction using Zone Budget has allowed demarcation of the losing and gaining stretches along the main stem of River Ganga as well as some of its principal tributaries. From a management perspective, and entirely consistent with general understanding, it is seen that unabated long term groundwater extraction within the study basin has induced a sharp decrease in critical dry weather base flow contributions. In view of a surge in demand for dry season irrigation water for agriculture in the area, numerical models can be a useful tool to generate not only an understanding of the underlying groundwater system but also facilitate development of basin-wide detailed impact scenarios as inputs for management and policy action.

Study region: Ganga River basin.
Study focus: The availability of freshwater has been recognized as a global issue, and the reliable evaluation and quantification of it within the basin is necessary to bolster the sustainable management of water. For this purpose a basin-scale SWAT model of the Ganga River basin has been developed.
New hydrologic insights for the region: Model validation showed that simulated results were consistent with the observed data in reproducing the seasonal dynamics of surface water and suggest that the model is capable of reproducing the hydrological features of the basin including the snow melt. However, there are large variations in both temporal and spatial distribution of the hydrological components. Statistical methods have been used for detecting trends and critical changes in streamflow. It has been found that although the streamflow from the snow fed areas has increased, the stream flow in the lower reaches and the non-perennial tributaries have declined significantly. This decline can be attributed to both anthropogenic and exogenous changes. The study also establishes that there has been a substantial reduction in overall water resources availability with respect to Virgin. This information sets the yardstick to the restoration of the hydrological and environmental health of the basin and can lead to better management of water resources under scarcity.

The Ganga is an international transboundary river that flows across three major riparian countries: India, Nepal, and Bangladesh, where India shares a significant proportion of the total basin area. The river system is highly dynamic and regularly floods in all three countries due to abundant rainfall in a short period of only four months each year that causes tremendous loss of both property and human life. In this study, we have done a synoptic review to synthesize the hydrology, hydrogeology, and modeling studies that have analyzed hydrological changes and their impacts in the Ganga basin. This review also identifies some of the knowledge gaps and discusses possible options for enhancing the understanding of sustainable water development and management. This review indicated that transparent data sharing, use of satellite-based observations along with in-situ data, integrated hydro-economic modeling linked to reliable coupled surface–groundwater models, a central shared decision support center for early warning systems to deal with hydrological extremes, joint river commissions and monitoring teams, and multilateral water sharing treaties (agreements) are required to promote sustainable and equitable distribution of water resources and to avoid water sharing conflicts in the Ganga basin.
