The adoption of micro-irrigation projects has resulted in water saving, yield and income enhancement at the farm level. However, the overall impression is that they are capital-intensive and suited to large farms. In this context, a study was undertaken in nine states, mainly to examine the actual area covered compared to the potential area and to understand the adoption level of mias well as to analyse the cost and returns under different farm categories. The results indicated that only about 9% of the mi potential is covered in the country. Key uggestions include reduction in capital cost of the system, provision of technical support for operation after installation, relaxation of farm size limitation in providing subsidies and the establishment of a single state level agency for implementation of the programme.

Groundwater is now a major source of agricultural water supply in many parts of the world. The value of groundwater as a new source of supply is well known. However, its additional buffering or stabilization value is less appreciated and even less analysed. Knowledge on groundwater’s stabilization value is advanced by developing and estimating an empirical model using the case of tank irrigation systems in Tamil Nadu, India. Unlike previous work, the model uses cross-sectional rather than time-series data. The results show that for the case-study region, the stabilization function added approximately 15% to supply value. Scenarios with surface water and electricity price were incorporated in the model. Increased surface-water supply and electricity price caused reduction in groundwater use but the percent of stabilization value of groundwater increased. The findings are used both to suggest improvements in tank irrigation systems and to further contextualize knowledge of groundwater’s stabilization value.

A hybrid model incorporating the econometric and programming models was developed to quantify the impact of climate change on agriculture in Godavari basin, India. The Just and Pope production function was used to estimate the mean yield of crops and the variance associated with the mean yield and using the estimated yield, the multiple goal programming model was used to optimize the land and water use under mid and end century climate change scenarios. The results indicated that rice production will reduce during mid and end-century periods by 16% and 36% respectively and by incorporating the water and labour saving technologies in the crop production, the reduction in rice production will be eliminated during mid-century and it will be only 19% during end-century period. The overall water saving will be about 20% due to the adoption of these echnologies. Technology up-scaling programs are suggested. Areas for future research are also indicated.

Even though there has been increasing development of water management technologies over the years, the adoption rate by the farmers is comparatively small ranging from only 15–20%. Hence it is timely to look at the return to water management research investment to fine tune investment in future research. A detailed study was done using the data from Tamil Nadu State, India. The successful technologies yielded a moderate return ranging from 11–20%. With higher adoption levels of the water management technologies, the rate of return will be higher. Strategies to boost technology transfer and upkeep should be given importance in water management programmes.

Access to sufficient quantities of water of acceptable quality is a basic need for human beings and a pre-requisite to sustain and develop human welfare. In cases of limited availability, the allocation of water between different sectors can result in conflicts of interests. In this study, a modified version of the Building Block Methodology (BBM) was demonstrated for allocation of waters between different sectors. The methodology is a workshop-based tool for assessing water allocation between competing sectors that requires extensive stakeholder involvement. The tool was demonstrated for allocation of water in the Sri Ram Sagar water reservoir in the Godavari Basin, Andhra Pradesh, India. In this multipurpose reservoir, water is used for irrigation, drinking water supply and hydropower production. Possible water allocation regimes were developed under present hydrological conditions (normal and dry years) and under future climate change, characterized by more rain in the rainy season, more frequent droughts in the dry season and accelerated siltation of the reservoir, thus reducing the storage capacity. The feedback from the stakeholders (mainly water managers representing the various sectors) showed that the modified version of the BBM was a practical and useful tool in water allocation, which means that it may be a viable tool for application also elsewhere.

Many rural poor people in developing countries depend on agriculture and are highly influenced by climatic change. Hence, sustainable livelihood approaches are used at both policy and project level to initiate new poverty reduction activities and modify existing activities to improve livelihood incomes. Practices relevant to climate change adaptation around the world are wideranging and include development of technology, management, infrastructure, livestock, groundwater, and knowledge. Both structural interventions (such as building flood embankments, dikes, or seawalls or enhancing the natural setting or landscape) and nonstructural interventions (policies, knowledge development, awareness, methods and operating practices, including participatory mechanisms) have helped to reduce the impact of climate change. Further, market-based instruments such as credits and crop insurance were also developed to help poor households in many developing countries to cope with the uncertainties. The uptake of such adaptation practices is lagging, however, but informal institutions are playing a key role as they rely on enforcement methods and are not supported by the government. Mainstreaming adaptation and enhancing adaptive capacity could be increased by encouraging partnerships between informal processes and formal interventions to facilitate adaptation by the poor. The cost of adaptation is also significantly higher in developing countries. Nonetheless, more attention is needed in addressing future climate scenarios through agricultural research and development, irrigation development, infrastructure, and improved irrigation efficiency.

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.
