small landholders can implement a range of climate smart agricultural practices and technologies, in order to minimize the adverse effects of climate change and variability, but their adoption largely depends on economic benefits associated with the practices. To demonstrate the potential economic benefits of CSA practices, we conducted a study with smallholder farmers in the Indo-Genetic plains India. Among the CSA practices and technologies including use of improved crop varieties, laser land leveling, zero tillage, residue management, site specific nutrient management and crop diversification, a majoriry of the farmers prefer to use improved crop varieties, crop diversification, laser land leveling and zero tillage practice. we estimated the cost of adoption, change in yields and importer for the implementation if three major
