Climate change and agriculture are interrelated global processes. A change in climate affects agricultural production in multiple ways. Rise in temperature increases the pest’s vulnerability to different crops and change in rainfall pattern reduces water availability and also affects both the irrigated and rainfed farming activities. The aim of this review is to map published literature on impact of and adaptation to climate change in agriculture by categorising papers according to their focus on concept of climate change and variability, extreme weather events, rainfall variability, temperature variability, adaptation to climate change in agriculture and factors influencing the adaptation strategies. Systematic searches were conducted through ‘Google scholar’. For this study only those journal’s articles were considered which are available at ‘Web of Science’ and ‘Scopus’ databases. The study also includes reports which were published by international agencies since 1992. A total of 112 publications were retrieved, of which 58 met the inclusion criteria for the systematic review. These 58 publications were categorised and discussed thematically. A synthesis from various studies finds that inter-annual and seasonal variability of rainfall is a major cause of fluctuations in the production of agricultural crops and increasing temperature has negative effects on major agricultural crop production. The study also indicates that adaptations available to farmers vary according to the local conditions and the particular farming system. Access to agricultural extension, credit, land availability, farm income, education, family size, gender, age, farming experience, farm size, access to market, access to climate information and improved technologies are found as significant factors influencing adaptation practices.
