Under global warming and as well as increase inCO2 concentration, the crop
production is likely to be affected significantly by influencing the crop physiological
processes. In this study, the crop growth, yield, water productivity and water footprints
of maize were worked out with 1 OC and 2 OC increase in prevailing ambient
temperature from the base line data 1983-2010at present (370 ppm) and 550 ppm CO2
concentrations using Decision Support System of Agro technology Transfer (DSSAT
4.5) model. The result of the model was validated with field experimental data of
Dhenkanal, Odisha. Monitored ecosystem CO2 emissions and sequestration by
agricultural crops, gross primary productivity, ecosystem respiration, net ecosystem
exchange and energy balances of rice based cropping system (rice-okra-tomato).The
effect of climate change with respect to rainfall fluctuations on the groundwater water
table and groundwater recharge was analysed. The available data set of rainfall and
water table clearly reveals the uneven and erratic pattern and effect of climate change.
To compensate the crop evapo-transpiration loss in view of the climate change,
pressurized irrigation system was implemented in canal command and groundwater
irrigated areas to enhance water use efficiency in vegetable crops. Location specific
groundwater recharge techniques suitable for geo-hydrological conditions were
developed and tested for their performance in terms of recharge rate and area of
influence.
