Abstract: This paper assesses the distribution of climate change impacts on agricultural Total Factor Productivity (TFP) across districts in India. Combining the district-level TFP, estimated using multiple rounds of nationally representative agricultural surveys, with climate and other controls, the relationship between production efficiency and climate is estimated for two time points: 2002–2003 and 2012–2013. The estimated climate response function suggests that for every 1 °C rise in temperature, agricultural productivity reduces by ∼4.5%. Using estimated climate sensitivity and regionally downscaled climate projections, the study further assesses the impacts on agricultural TFP across districts over the mid-century. By 2050, TFP in agriculture is projected to decline for all the states considered in the study. The latter-period (2012–2013) climate response function projects more adverse impacts compared to the early-period (2002–2003) response function. The results also show increase in the magnitude of impacts over time, indicating that Indian agriculture has become more climate sensitive.
