Er. Fosse et Sa. Changnon, POTENTIAL IMPACTS OF SHIFTS IN CLIMATE ON THE CROP INSURANCE INDUSTRY, Bulletin of the American Meteorological Society, 74(9), 1993, pp. 1703-1708
Several studies have estimated the possible impacts and adjustments in
U.S. agriculture resulting from a future change in climate. This pape
r examines how these adjustments and shifting climate conditions could
affect the nation's crop weather insurance industry, including its ab
ility to provide adequate coverage. Shifts in crop varieties, the exte
nsion of new crops into new areas, and changes in crop yields would al
l affect establishment of rates and many other industry practices, but
we expect that these shifts could be adjusted to using existing techn
iques and field research. What will be most difficult to react to will
be the shifting weather risk, such as ever-changing storm frequencies
or intensities. Current practices of rate development and regulation
of insurance rates are based on historical data, not on anticipation o
f future weather shifts. Outcomes seen during such climate transition
periods with their inherent uncertainty include a reduced industry zea
l for accepting risk. This would likely include declination of coverag
e, reduced coverage per unit area, and lower yield guarantees. These a
cts would lead to more self-insurance by crop producers, which would i
nvolve more crop diversification and greater dispersion of crops over
an area.
