Is Federal Crop Insurance Policy Leading to Another Dust Bowl?

Federal crop insurance policy is rewarding Southern Great Plains farmers’ failure to adapt to drought and hotter weather, and encouraging practices that could lead to another Dust Bowl, according to a new report by the Environmental Working Group.

Crying Wolf

The congressional budget deal signed by President Obama in early November includes a cost-saving measure that trims the profits taxpayers guarantee the crop insurance industry. The guaranteed rate of return of these companies would drop from 14.5 percent to 8.9 percent, saving $3 billion over the next 10 years.

Crop Insurance: An Annual Disaster

When you buy home or car insurance, you expect to collect only when there’s a disaster – a tornado, a hailstorm or a collision. If there was a policy that paid out year after year, you only had to pay less than half of the premium and you’d actually make money from buying it, you’d jump at it – but the insurer would be foolish.

"Washout" Revisited: Survey finds modest progress combatting Iowa soil erosion

In 2013, an Environmental Working Group report titled “WASHOUT” documented that soil erosion across Iowa farm land during that spring’s heavy rains had been far worse than previous estimates – in some cases carrying away a devastating 40 tons of soil in a single week from fragile and poorly protected fields. In many places, runoff carved “ephemeral gullies” as a result of growers’ inadequate conservation measures.

Elementary School Students At Increased Pesticide Risk

EWG has determined that 487 elementary schools across America are within 200 feet of a corn or soybean field. This finding is alarming because young children are especially vulnerable to the toxic herbicide 2,4-D in Dow AgroSciences’ Enlist Duo TM, a weed killer mixture that is awaiting governmental approval for widespread use on new varieties of genetically engineered corn and soybeans.

Broken Stream Banks: Failure to maintain buffer zones worsens farm pollution

Water pollution from farmland is a major problem in southern Minnesota and wherever row crops dominate the landscape across the United States. Much of this pollution can be prevented by the conscientious use of riparian buffers – strips of grass, trees or other permanent vegetation maintained along the banks of rivers, streams, lakes and other waterways.

Washout: Spring Storms Batter Poorly Protected Soil and Streams

Media attention has understandably focused on flooding, especially given the devastating floods that have repeatedly struck the region in recent years.This year, it looks as if the Midwest will dodge the bullet – flooding has been damaging and heart-breaking for those affected, but nothing yet has resembled the scope and devastation of the 1993 and 2008 floods. But the Corn Belt’s rich soil and streams, especially in Iowa, haven’t been as lucky. The storms that pushed streams and rivers out of their banks have battered largely unprotected cropland soils throughout the region, sending tons of mud and farm chemicals into road ditches and streams across the heartland.

Many counties where federal crop insurance subsidies rose between 2008 and 2012 also had an increase in poverty over that period, a finding that undermines the oft-repeated arguments that farm subsidies help reduce rural poverty, an Environmental Working Group analysis shows.

Paradise Lost: Conservation Programs Falter as Agricultural Economy Booms

The reality is that the nation’s primary prairie and wetlands protection program – the USDA’s Conservation Reserve Program (CRP) – was not designed to meet the environmental challenges being created by record prices for farm commodities. Because the majority of the land in the program is taken out of agricultural production under 10- and 15-year rental agreements with the owners, cropland that had been “restored” with grasses and trees is increasingly being plowed under to grow crops again as soon as these agreements expire. As a result, the benefits of taxpayers’ investment in these short-term agreements have proved to be fleeting.
