This work aims at developing an understanding of the vulnerability
agricultural system as a whole (as distinct from individual crops)
climate variability. Year-to-year variations in the quantity
and value of
agricultural output may be caused by a variety of factors, in
climate is only one. Using national and state-level data for:
production and value of output for a range of agricultural commodities
including foodgrains, cereals, cash crops as well as fruits and
vegetables, we are examining the following questions:
- as the mix of crops and their relative proportions has changed
last four decades, is there any observable change in the total
the output, after accounting for climate variability?
- The Green Revolution caused a significant change in the productivity
well as crop mix in certain states. Is there a difference in
variance before and after this event?
