In the present study, the review of the literature has been made to appraise the impact of climate change on crop water requirement, availability of irrigation water and suggested coping strategies. Most of the studies presented indicate that there is an increase in irrigation and crop water requirement. There are few studies which suggest that there may not be a change in crop water requirement in event of climate change. The studies also suggest that climate change would affect groundwater recharge and water availability for irrigation. The different studies revealed that the future will be tough for nations in the sensitive areas in particular whose irrigation water supplies are dependent on groundwater. To overcome the crisis of irrigation water shortage in the coming decades some coping strategies suggested by the various scientists are mostly generic in nature. Also, Effects of changes in climatic parameters which control the evapotranspiration have not been investigated in detail. In overall various studies shows the complex results based on the crop production and locations. Therefore, this initiates to review the climate change impacts on water availability and water demand for irrigation. This study will help to identify the gaps and scope for future research so that suitable adaptation and mitigation measures can be taken for water resources planning and management under climate change scenarios.
