“…Th e simulations of rainfed maize, sorghum and rice yields also indicated the adverse eff ect due to increases in temperatures, although increased rainfall and change in management practices can partly off set these eff ects (Kattarkandi et al, 2010;Srivastava et al, 2010).

“…Several adaptation measures have already been examined by researchers. For example, Palanisami et al (2011) have examined the adaptation measures such as systems of rice intensifi cation, machine transplanting, alternate wetting and drying and maize water management options and incorporated them in the optimization model that could help minimize the incidence of climate change impacts on crop yields, labour use and water use. In addition, there are various other adaptation practices, such as direct seeding of rice and drum seeding of rice, which are gaining acceptance among farmers (Gurava .…”

Th e agriculture sector is highly vulnerable to climate change in many parts of the world. Th ere is an increasing concern among farmers, researchers and policy makers about the potential impacts of climate change on food security and livelihoods. Researchers are using several climate change models to make an assessment of the impacts and identify adaptation strategies. Th e present chapter reviews the current state of understanding of the climate change impacts on irrigation water in South Asia and specifi cally on the crop yield and relevant adaptation measures in three major river basins (Godavari, Krishna and Cauvery) in India. Optimization model was used to evaluate the diff erent adaptation practices and their potential to maximize rice production and income, and minimize water use for the mid-and end-century climate-change scenarios. Adaptation practices such as systems of rice intensifi cation, machine transplantation, alternate wetting and drying (AWD) and direct seeding could reduce the water and labour use by 10-15% and stabilize rice production in the long term. Th e study suggests the need for technology upscaling, which should be backed up with well-planned capacity-building programmes for the farmers.

Climate change characterized by global warming has become a hotspot of research in recent years for water resources, agriculture, ecology and other disciplines. In India, studies have shown an increasing trend in surface temperature, with decreasing trends in rainfall. Farmers are also more affected by the climate variability which has a serious influence on their production and income. The climate change and adaptation (ClimaAdapt) programme was implemented from 2012 to 2016 to build farm‐level capacities and enhance the adaptive capacity of the agricultural and water sectors in the Krishna basin of Andhra Pradesh and Telangana states. Water‐saving interventions such as direct seeded rice, a modified system of rice intensification and alternate wetting and drying (AWD) of rice were implemented in a cluster approach and enhanced water productivity. The training and implementation programmes increased the adaptation and awareness of farmers. Water measurements were carried out by using flumes and ultrasonic sensors. The area under direct seeded rice has increased to 64% in the study district and 77% of the trained farmers are adopting the practice. Capacity building, implementation and science–policy linkages are the key pillars of the programme to improve the adaptive capacity and scaling‐up of water management practices.

“…Agricultural production will face uncertainty, as there is regional variation of rainfall, temperature, soils, crop yields, cropping systems and management practices (Palanisami et al, 2011). The crop losses may increase further, if the predicted climate change increases the climate variability.…”

Purpose – Researchers and policymakers are figuring out the adaptation technologies to cope with the changing climate. Adaptation strategies for crop production followed by the farmers at selected study locations had ranged from 6-30 per cent only, and this was mainly due to lack of awareness about the actual cost associated with adaptation and non-adaptation of these strategies. Design/methodology/approach – Hence, this study aims to address the cost of adaptation for rice using joint probability distribution of rainfall and crop prices. Findings – Cost of adaptation varied from INR2,389 to 4,395/ha for System of Rice Intensification (SRI); INR646 to 1,121/ha for alternate wetting and drying (AWD) and INR8,144 to 8,677/ha for well irrigation (WI), whereas expected cost for not using these technologies has ranged from INR6,976 to 9,172/ha for SRI; INR4,123 7,764/ha for AWD and INR10,825 to 17,270/ha for WI. Hence, promotion of the adaptation technologies itself will minimize the income losses to the farmers. Research limitations/implications – Even though, there are many ways for farmers (other than technology), to adapt to climate change (such as out-migration to cities, selling farm assets, focus on children’s education, etc.), this report, given the framework of the major research study undertaken, addresses only farm-level adaptation of the technologies to enhance farm income. Originality/value – Public–private partnership in providing the technologies at cheaper costs, capacity building in handling the technologies and creating awareness about the technologies to minimize the expected cost of adaptation are suggested to improve the adoption level.
