Climate induced hazards has increased production threats to agriculture where such environmental risks can significantly reduced by adapting adaptation measures. In farm based adaptation measures specifically the autonomous adaptation aspect has not properly focused particularly in developing countries like Pakistan. This study attempted to investigate on-farm autonomous adaptation (OFAA) measures of wheat farmers to climate change and estimate its impact on wheat yield and total return. This research work used the data of 480 wheat farmer from production based six categorized higher vulnerable districts of Punjab, Pakistan. Probit model was employed to examine adaptation decisions determinants of farmers and Propensity Score Matching used for to investigate the impact of OFAA practices on outcomes of wheat crop. Estimates indicated as wheat farmers to reduce the unfavorable effects of climate change have applied different OFAA strategies such as seed varieties changing, fertilizer management, variations in cultivation dates and management of supplementary irrigated water. Probit model estimates illustrated as climate information access, credit access, ownership of land, off-farm income and ownership of tubewell considered significant determinants regarding adaptation decisions of farmers. Estimates of propensity score matching indicated as farmers those applied almost one OFAA strategy obtained 310kg per hectares higher wheat yield as US$82.75 per hectares return rather than those not applied any adaptation strategies. Adapter wheat farmers applied multiple adaptation strategies obtained higher yield and return rather than adapter farmers used limited adaptation strategies. Results imply as in developing sustainable farmers livelihood, adequate food production, reducing crops variability and climate change adverse impacts it is mandatory to applications of OFAA measures. The study also elaborated as for developing farm-level adaptation there is significant role of climate information, farmers schooling, access of credit and adequate irrigation.
