Rainfall Index Basic Concept
Aug 30, 2010
Q: What are some of the basic concepts of the Rainfall Index Pasture, Rangeland, Forage (RI-PRF) Insurance Program?
A: The Rainfall Index is an area-based plan of insurance, and is based on a National Oceanic and Atmospheric Administration Climate Prediction Center
(NOAA CPC) interpolated rainfall
data set and uses a 0.25 degrees in latitude by 0.25 degrees in longitude. Producers must select at least two, two-month time periods
in which precipitation is important for the growth and production of the forage species.
These time periods are called Index Intervals. Insurance payments to a producer are calculated based on
the deviation from normal precipitation interpolated to the grid and index interval(s) selected. This insurance
coverage is for a single peril - lack of precipitation. It is critical that producers review the historical indices for their
grid ID to determine how well the past results correspond to their past observations.
Q: Can I just insure the acreage where my best improved grasses are grown or do I have to insure all of my pastures?
A: You may choose to insure grazing land, hay land, or both. You are NOT required to insure 100 percent of the crop type's insurable acres in the county.
Q: Can my pastureland be insured for grazing in one year and for haying the next year?
A: The crop type and associated insurance can vary from year to year and this determination will be based on the
intended use; however, if you change crop types, intended use, and insured acres, you must contact your
insurance agent to make the appropriate changes to your policy, prior to the acreage reporting date.
Q: Are there a minimum number of acres which I can insure?
A: No. However there are minimums and maximums that can be insured in any one interval.
Q: Can I insure my hay land that I annually plant to a forage crop?
A: No. You cannot insure acreage with annual plantings. However, there are provisions that allow overseeding into an established perennial pasture.
Q: If I establish an improved forage pasture, how long do I have to wait until I can insure these acres?
A: The policy states that land is insurable as long as it is not initially planted to a forage crop after
July 1 of the previous crop year, unless allowed by the special provisions. For example, the land could be insured
in 2010 if planted before July 1, 2009.
Q: Is overseeding into established acreage of existing forage crops, which are not planted annually, an acceptable farming practice and not considered as an annual planting?
A: Yes. Overseeding into established existing forage crop acreage, which are not annually planted, is an acceptable practice in the Rainfall Index Pasture, Rangeland, Forage Insurance Program.
Q: Can my Farm Service Agency (FSA) maps be used to determine acreages for my policy?
A: Yes, FSA maps and records are acceptable for determining insurable acreages for your policy.
Q: Will I be able to insure my Conservation Reserve Program (CRP) land?
A: Acreage enrolled in other types of USDA programs is not eligible. Also, due to the fact that CRP programs prohibit grazing and haying,
land in a CRP program is considered uninsurable acreage.
Q: Can I insure the waterways around my row crop fields that I hay for my livestock?
A: Yes, if it is declared as hay land, and you intend to hay the acreage during the upcoming crop year.
Q: Can I insure my grazing land that is located within a city limit or within a deed restricted area?
A: Yes, if it can legally be used for grazing and you intend to graze the acreage during the upcoming crop year.
Q: How do I determine the value per acre of my grazing land?
A: You may select a value for your grazing/hay land that is between 60 and 150 percent (protection factor)
of the county base value per acre, depending on your costs/revenue expectations for your
Q: Will the value be the same for all of the grazing land in my county?
A: Yes, county base values are determined and provided on a county basis, they will not change for each grid.
Q: What is the protection factor and why is it included in the program?
A: A percentage factor selected by you that allows you to individualize your coverage based on the productivity
of the crops you produce and may be between 60 and 150 percent. Only one protection factor may be selected
per county and crop type.
Q: Will the county base value of a grid be changed from year to year?
A: The county base value will be updated when grazing land and hay land values within an area change.
It is anticipated that these values will be updated or evaluated on a periodic base of three to five years,
Q: Why do I have to select two intervals if I get most of my grazing in only one?
A: You must select at least two intervals because total production per year is influenced by rainfall in more than one interval.
Q: If my grid has a loss, how will I be notified of my loss?
A: Based on your policy, your insurance company will automatically send you an indemnity payment once the final grid index is
determined and if the final index value is below your trigger grid index, assuming all qualifications of the policy are fulfilled.
Once published, you can check on the
RMA Web site for official final index values.
Q: Does the rainfall index predict forage production on each insured's operation?
A: The rainfall index does not explicitly predict individual forage production on a given producer's operation. Instead, the index is simply a reflection of how much precipitation is received for a given 2-month interval for a specified weather grid, declared by the producer, relative to a long term average for the same interval and grid. Research indicates that rainfall is highly correlated with forage production, but does not directly predict forage production.
Q: What is the trigger grid index?
A: It is the result of multiplying the expected grid index by your selected coverage level.
Q: How many years of rainfall data is used to determine the average rainfall for this
A: NOAA CPC has kept records since 1948, which are used in calculating the "normal" rainfall index for each interval
and grid ID.
Q: Can I follow the rainfall status of my grid during the interval which I have chosen to insure?
A: You will always be able to look at the historical rainfall during the interval that you have chosen, but the current
interpolated rainfall data, used in the program will only be reported on the RMA Web site after the end of the index interval.
Q: If I keep the official rainfall records for a local weather station, can I then use these records for my selected grids?
A: No. The final grid index will be determined by FCIC based on NOAA's CPC current 0.25 degree grid interpolated
precipitation data for each grid ID and index interval during the crop year. The interpolated precipitation is based on
multiple weather station and other data and cannot be traced to a single point. It is also important to
remember that as stated in the Rainfall Index Pasture, Rangeland, Forage crop provisions:
this program is designed as a risk management tool to insure against widespread loss of production
of the insured crop in a designated area called a grid. It is primarily intended for use by those
producers whose forage production correlates with the average interpolated precipitation patterns for the
selected grid. It is possible for you to have reduced forage production on your insured acreage
and still not receive a payment under this plan. Please contact a qualified crop insurance agent
for more information.
Q: What is a grid index?
A: A calculated value utilizing each grid's current and historical interpolated
precipitation data for each grid ID and index interval. The index is expressed as a percentage.
Q: What are the origins of the grid ID system?
A: NOAA CPC has used the 0.25 degree grids to report weather for many years. It is based on data from
reporting weather stations, enhanced with NEXRAD and satellite cold cloud data. Multiple weather station data is weighted
and interpolated by NOAA CPC to each grid.
Q: Will I have to provide the Grid ID numbers to my agent, or will he or she be able to help me locate them?
A: You can determine the grid ID yourself, or your agent will be able to help you locate them. It is recommended that during the application, the agent be involved to ensure you meet all the policy requirements.
Q: If I have five pastures located several miles apart, will I be able to insure them separately, or will I have to put them all together?
A: It depends, if they are in different grids they will have to be insured in the grid in which they are located.
Q: If an applicant has non-contiguous acreage which is located in separate grids, can he/she opt to
use one point of reference for all the acreage and use only one grid ID?
A: No. A point of reference must be selected for each separate, non-contiguous acreage of the crop that is
located in the county. If the non-contiguous acreage is located in separate grids, each non-contiguous
acreage must have a separate grid ID.
Q: Can all contiguous acreage of the crop type be combined into a single grid ID using one point of reference for all of the acreage, including acreage that extends into an adjoining numbered grid or county?
A: All contiguous acreage of the crop type may be combined into a single grid ID using one point of reference for all of
the acreage, including acreage that extends into an adjoining numbered grid or county.

Q: Can a new application be accepted at anytime the first time an insured applies?
A: New applications must be submitted prior to the sales closing date as outlined in the actuarial documents for the given crop year.
Q: Will I have to supply fertilizer records or other management records if I have a loss?
A: No. Individual inputs and records are not required. Losses and indemnities are determined by the final index values.
Q: Does the Web site servicing the Rainfall Index PRF Insurance Program
require internet access and can the information only be used electronically?
A: The Rainfall Index PRF Insurance Program system has been developed as an
interactive Web site that a user can navigate to collect information and establish a grid ID. The system
also allows screen printing, including the maps and grids. Contact your approved agent for available options.
Q: With the written approval of the insurance provider, may the insured assign rights to an indemnity
payment to someone else for the current crop year?
A: Yes. The insured may assign rights to an indemnity payment to another party for the current crop year.
