New research raises questions about federal conservation spending
By Jane Shaw Stroup of The Independent Institute.
"The Department of Agriculture (USDA) is a giant agency with a $481 billion budget, 65 percent of which goes to the food stamp program. As the 2026 farm bill nears passage this autumn, the public is watching a bitter partisan debate over food stamps. But few people—other than insiders—are scrutinizing the rest of the bill. Yet other agriculture programs, although minuscule compared to food stamp benefits, deserve attention, too. The USDA pays $5.3 billion a year for its conservation programs. Two recent studies raise questions about their effectiveness and appropriateness.
Woody Encroachment
Let’s start with woody encroachment. This is the unplanned intrusion of trees and shrubs into croplands and grasslands. Such vegetation reduces the amount of land that can be used for raising crops or grazing cattle, thus reducing production.
In 2019, the Natural Resources Conservation Service (NRCS, an agency of the USDA) started the Kansas Great Plains Grassland Initiative (KGPGI). Its goal was to end, or at least slow, woody encroachment in Kansas. Two researchers from Kansas State University studied this problem carefully.
Between 2017 and 2024, the USDA spent only $24 million addressing woody encroachment in Kansas, while the problem was causing landowners $30 million in forage losses each year (and even more in Oklahoma and Texas). Surveying landowners of Kansas cropland, the researchers found that between 41 and 61 percent of the landowners saw this encroachment as a major problem. Yet relatively few were participating in the government’s Environmental Quality Incentives Program, which provides payments for addressing environmental issues such as this.
So why the low participation? The researchers, Jackson Lindamood and Gabriel S. Sampson, found “high [tree and shrub] control costs, labor constraints, and difficulties prioritizing treatment areas,” as well as landowners’ “limited awareness, uncertainty about eligibility, and program complexity.”
The authors then began an economic study to calculate the impact of woody encroachment on land values, knowing there might be benefits as well as losses. They selected more than 12,000 parcels for which they had land sale prices and environmental data from 1990 to 2024.
Very simply, they found that woody encroachment increased land values. “The value of a one percentage point increase in woody cover on the parcel is associated with increased per-acre value ranging from $9 to $27 depending on model specification,” they wrote. This new vegetation was providing habitat for wildlife, which encouraged recreation, especially hunting—a service that was more valuable at the margin than raising crops or grass alone.
They called their findings “somewhat of a management and policy paradox: landowners face high costs to control woody encroachment on grassland, yet the land market places a land value premium on woody cover.”
So perhaps woody encroachment is a good thing and should be left alone? It’s not clear whether the researchers saw it that way. “This suggests a clear role for policy interventions that substantially lower the costs of control, have clear eligibility guidelines, and are easy to navigate for producers or landowners,” they wrote.
CRP and Land Values
There is something amusing about the upside-down effect of woody encroachment, but to me, there is something disturbing about a recent study of the Conservation Reserve Program (CRP). Unlike the woody encroachment program, the CRP—the USDA’s largest conservation program—pays farmers to reduce their usable acreage by setting aside marginal or erodible land. Started formally in 1985, it has two goals: increasing natural habitat and, by reducing farmland, keeping up crop prices.
This year, the environmental research organization Resources for the Future (RFF) produced a comprehensive working paper by Matthew Wibbenmeyer et al. on the effect of the CRP on nearby property values.
The paper begins: “Conservation is often perceived to be at odds with economic activity.” Specifically, the government’s “payments for eco-system-services” under the CRP has caused anxiety that its “spillover effects” may be harming rural communities. This could happen “by reducing outputs, employment, and demand for support services from agriculture, forestry, or other land-based industries.”
On the other hand, they continue, there are also benefits, such as “improved environmental quality, recreational amenities, and landscape resilience to erosion, extreme weather, and ecological disturbances.”
The RFF used CRP data and residential property values to find out if CRP land affects the value of nearby homes. And it does. They write: “a 10-hectare [2.47-acre] increase in CRP enrollment [by landowners] results in an approximately 4 and 1.6 percent increase in the value of homes within 500 and 1,000 m[eters], respectively.” Nationally, this adds up to an increase in residential property values by $775 to $900 million per year.
So a government payment program to keep up prices and protect the environment raises the value of nearby land. That’s nice, but should taxpayers pay money to raise the land values of what may be well-heeled homeowners who aren’t, as far as we know, doing anything special to protect the environment? Whatever the answer, the question is largely irrelevant. The paper seems to be a strategic effort to boost the CRP.
Over the years, the CRP has not shown environmental benefits that are dramatically greater than costs. In fact, in 2007, Leroy Hansen, an economist at the USDA’s Economic Research Service, wrote that: “Nationally, the CRP is estimated to provide $1.3 billion in annual benefits, which represents 75 to 80 percent of the program’s cost.” In other words, by cost-benefit standards, it is a net loss. This study by RFF gives support to the benefit side.
These two cases suggest that members of the public should take a closer look at the USDA’s conservation programs."
