2 Improving Groundwater Levels and Quality through Enhanced Water Use Efficiency in Eastern Indian Agriculture. Objectives:
(i) Development of a few representative Digital Catchments in eastern India for better understanding of their spatio-temporal dynamics and water balance across various hydrologic reservoirs and their underlying cause/effect relationships at different scales.
(ii) Monitoring aquifer recharge and recovery pertaining to present agricultural and other activities at different spatial (field, catchment) and temporal (monthly, seasonal, annual) scales using wireless technology.
(iii) Evaluation of different storm-water management, innovative agricultural water management, conjunctive use of surface and ground water, and aquifer recharge techniques for reversing the declining trend of groundwater table in the study aquifers.
(iv) Study of the effect of climate variability on water resources availability in general and soil moisture availability in the root zone in particular for the eastern India through pilot experiments, historical data analysis, and simulation modeling.
(v) Formulation of regional up- and downscaling relationships for root zone soil moisture and groundwater recharge attributes using field experiments and available ISRO and NASA satellite remote sensing data.
(vi) Development of a Decision Support System (DSS) for determination of best management practices (BMP) for all scenarios of water resources management for the study catchments and groundwater aquifers and extrapolation of the findings to other basins.

3 Measurement to Management (M2M): Improved Water Use Efficiency and Agricultural Productivity through Experimental Sensor Network
Objectives: (i) To develop an experimental sensor network for monitoring of climate, soil (nutrient and fertilizer), and water conditions during the crop growing seasons at field scales;
(ii)To develop a regional crop monitoring system using the historic and near real-time remotely sensed vegetation index datasets that can monitor crop growth on a weekly basis;
(iii)To develop a hydrologic modeling framework at watershed and regional scales that can provide estimates of weekly soil moisture (drought maps), evapotranspiration, runoff, and
groundwater levels;
(iv)To use information from experimental sensor network, remote sensing monitoring and sophisticated hydrologic models to develop and test an irrigation scheduling and water management system;
(v)To evaluate the sensitivity of crop yield towards varying soil, water, and climate conditions taking information of key variables from the field and regional scale monitoring systems that can provide an assessment of potential changes in crop yields and water availability under climatic change conditions.
