This paper examines the socio-economic impact of proposed dam on cropland productivity of Mahadayi project, Karnataka, India. Systematic appraisal of dam and their designing by categories of classes on the basis of physical and chemical characteristics of soil has been done in favour of development of agronomic conditions for the study of proposed dam sites in Karnataka. The study is aimed at the effective utilization of land according to their classes. Documentation on the land capability classification is a versatile component in formulation effective land use planning before the construction of dam. Thus an attempt was made to evaluate dominantly occurring soils on four class’s viz. soil depth, soil texture, soil drainage and soil erosion. The study was focused on the evaluation of economics of crop production based on agro climatic condition of the study area and existing cropping pattern. This study is important as it explores how an input of water and nutrient would respond under variable climatic conditions. In addition,interactions of water supplies with fertilizer rates at optimizing these resources need have been investigated. This paper identifies key challenges and solutions for carrying out project-level economic analysis of adaptation to climate change, both stand-alone and integrated into broader development projects. Very few projects addressing adaptation thus far have been subject to in-depth and rigorous economic analysis for a variety of reasons, including a lack of guidance on how to deal with assessments of the impacts of climate change, as well as with estimating costs and benefits of adaptation under uncertainty. Our focus is on the agricultural sector, where the impacts of climate change have the potential to disrupt the livelihoods of rural populations in many regions and where adaptation must be given urgent consideration. Nevertheless, some of the approaches discussed are suitable to projects in other sectors.
