The sensitivity of agricultural productivity to climate depends strongly on crop selection.

India is a vast country with disparate climate variability and change signals from north-to-south and east-to-west. The mix of field crops like rice, wheat, jowar, corn and soybean, as well as speciality products like vegetables, flowers, nuts, fruits, etc, are also vastly different across the subcontinent. To understand the climate sensitivity of agriculture across such complex terrain that has a complex mix of climate variability, change and agricultural activities, it is important to carefully choose a metric to measure it.

Recent studies of climate sensitivity of agriculture in the US may point to an answer.

A measure of productivity for sustainable agriculture in India

Climate impacts on agriculture typically consider temperature and precipitation impacts on crop yields, profits per acre and such. These are considered partial measures of productivity since they don't include the sum total of all inputs and output to track the overall return on investment or ROI and the overall sensitivity of this ROI to climate variability and change.
