Climate and Hydrology Scenarios for the ClimaAdapt programme regions in Tamil nadu and Andhra Pradesh states in India

2013

Impact of climate change is likely to have serious influences on agriculture and water sectors and eventually on the food security and livelihoods of a large section of the rural population in developing countries. To improve the adaptive capacity of the agriculture and water sectors in the states of Andhra Pradesh and Tamil Nadu, ClimaAdapt Programme (Adaptation to climate change: An integrated science--‐stakeholder--‐policy approach to develop Adaptation framework for Water and Agriculture sectors in Tamil Nadu and Andhra pradesh states in India) is undertaken in selected pockets of Krishna (Left canal (DC4) and right canal of Nagarjuna Sagar (DC 21) in Andhra Pradesh) and Cauvery (Kalingarayan canal basin at Erode district and Ponnaniar reservoir basin at Thiruchirapalli district, Tamil Nadu) river basins. The first and foremost need of the project is developing climate and hydrological scenarios for identifying and upscaling appropriate adaptation technologies. From ClimaRice (a feeder project to ClimaAdapt), climate scenarios for the current and future were developed by International Pacific Research Centre (IPRC), Hawaii. Tamil Nadu Agricultural University (TNAU), Coimbatore and International Water Management institute (IWMI), Hyderabad in coordination with Indian institute of Technology (Madras), Chennai developed the hydrological scenarios. In the current study, these scenarios were extracted for the ClimaAdapt programme regions and presented for the impact assessment and development of adaptation strategies for managing the changing climate.
