Multiple Peril Crop Insurance
� Provides expensive, but comprehensive coverage
� Covers many types of risk
� High administrative costs
� High cost of capital� High cost of capital
� Relies on government subsidies
� Costs are increased for lower income countries
� Small farms
� Poorer access to reinsurance
� Poor actuarial performance
Index Insurance
1. Area-Yield Index Insurance
2. Weather Index Insurance
� Lower Administrative Costs
� Low asymmetric information problems� Low asymmetric information problems
� No individual loss adjustment
� Better potential than MPCI in lower income countries
� Several pilot programs with good progress
� Need more time to evaluate fully

Climate Change and Insurance
� Consensus that climate change is occurring and will affect farming
� Increases in temperatures
� More extreme rainfalls (drought and excess rain)More extreme rainfalls (drought and excess rain)
� Models do not agree on the extent
� Poor predictive ability on the regional level
� Climate change affects the weather risk
1. Changing the norm—the central tendency
2. Increasing variability—weather variance
Changes in the Central Tendency
� The price of insurance is very sensitive to shifts in the central tendency
� The majority of weather events occur around the central tendencytendency
� The central tendency is the foundation for establishing the pure risk

Sahel
Semi-arid region below the Sahara
• Dynamic climate largely due
to oceanic oscillations
• Unlike the Sahel, climate
change may lead to more
permanent changes

Sahel: Rainfall Distribution Using Data from 1900
to 1961
� Insurance contract for wheat farmers
� Indemnities when rain is below 425 mm
� Central Tendency: 510 mm
� Payout Threshold: 425 mm
� Pure Risk: 2%
Pure risk will likely result in insurance affordable to
households
Sahel: Rainfall Distribution Using Data from 1962
to 1989
� Central tendency is below payout threshold
� Insurance is inappropriate in this setting
� Central Tendency: 328 mm
Pure risk would make
insurance unaffordable for
households
� Central Tendency: 328 mm
� Payout Threshold: 425 mm
� Pure Risk: 44%
Sahel: Rainfall Distribution Using Data from
1990 to 2006
� Increases in rainfall reduced the weather risk
� Insurance would be affordable depending on other costs
(Delivery, ambiguity loading, etc.)
Pure risk may result in
affordable insurance for
households
� Central Tendency: 456 mm
� Payout Threshold: 425 mm
� Pure Risk: 6%
Climate Change Increases Ambiguity and
Catastrophe LoadsMisestimating the central tendency is very costly
Green distribution Insurer forecast in 1962
Blue distribution Actual loss experience of next 30 years
Insurers expecting climate change greatly increase
ambiguity and catastrophe loads

CHALLENGE –
Communicating information about climate change in a fashion that decision makers can use that information
Insurance and Climate Change
� Insurance can be appropriate in limited contexts of climate change because of effects on the price
1. Pure risk effects
� Depends on the degree of climate change
Depends on the type of change (central tendency and/or � Depends on the type of change (central tendency and/or variability changes)
2.Ambiguity and Catastrophe load effects
� Depends on the level of uncertainty regarding future changes (ability to forecast)
� Price signals can push households to make difficult decisions to adapt
Adaptation, Policy Interventions, and Climate
Change
� Households must adapt or experience increasing farm losses
1. Change farming practices
2. Transition out of farming2. Transition out of farming
� Governments and donors can help
� Insurance, by itself, is not a means of adaptation
� So governments must be careful if they choose to support insurance
� Insurance can be used to facilitate adaptation
(e.g., linking insurance, credit, and improved seed varieties in Malawi)
Insurance Subsidies and Farmer Production
Decisions
� Policy makers � premium subsidies for insurance
� Insurance subsidies and shifts in the central tendency
� Farmers make production decisions around central tendency
� Farmers incorporate insurance subsidies into production � Farmers incorporate insurance subsidies into production decisions
� This can distort household incentives to adapt—taking more risk at the government’s expense� Experience of developed nations with MPCI
� Insurance subsidies and increasing variability
� Farmers are less likely to change production decisions based on increasing variability
� Creates more opportunities for government and donor support
Insurance Facilitating Adaptation

� Cognitive failure prevents incentive distortions

Conclusions
� Government and donor support for insurance should be considered for crowding-in markets
� Insurance must be considered in the larger context of household adaptation to climate change
� Because so many needs exist, on-going premium � Because so many needs exist, on-going premium subsidies may carry high opportunity costs
� Regional uncertainty regarding climate change makes determining where insurance programs will be feasible difficult
� Improvements in forecasting can lower insurance costs and create new opportunities
