Cutting Conservation Funding Endangers our Food System

As part of the Trump administration’s overhaul of the U.S. Department of Agriculture, funding for several programs, including conservation contracts and local food purchasing for schools, was cut or frozen.

The lack of funding of these and uncertainty for other programs is already having a chilling effect on farmers and our food systems, and the impacts have been immediate and wide-ranging. These programs support critical conservation initiatives in agriculture—from assisting local farms and sustainable agriculture research to farmer technical aid. These local programs also support smaller-scale farmers to maintain local or heritage breeds such as Galloway cattle or Tamworth pigs that are not suitable for large-scale, industrial agriculture.

As a result, farms and livelihoods throughout the country are threatened. These programs provide vital support for U.S. agricultural infrastructure and long-term sustainability including the diversity of food available to the public. The link between biodiversity and food security is well known—vibrant biotic life supports soil fertility, pest control, pollination, water quality, and sustainable agriculture. Genetic biodiversity in our foods is also important—domesticated plants and animals that are genetically diverse are less likely to succumb to the same diseases or pests, and many have adapted to a range of environmental and climatic conditions. The more genetically diverse our food system is, the less vulnerable it is to collapse.

Local breeds are living genetic repositories. They are the result of long-term histories and cannot be simply made in a laboratory. They are the future of our food security.

For this reason, conservation efforts must include protecting domestic animal breeds to establish living genetic banks for future food security during times of abrupt climate change. Unlike plants that can be propagated from seeds stored in vast seed banks, the most efficient way to maintain biodiversity in domesticated livestock is by keeping herds of local or heritage breeds, since sperm cryopreservation is expensive; susceptible to damage or loss; and limited to rich, industrialized nations and communities. Breed conservation can occur on a local level and doesn’t need to be expensive—it’s been successfully done in the past.

Almost 100 years ago, Texas longhorns—the iconic emblem of the state of Texas—almost went extinct. At the time, American tastes in meat favored fattier cattle breeds and the lean, grass-fed longhorns were unpopular, difficult to transport in railroad cars due to their big horns, and not economically viable for ranchers. This breed already had a long history in the area and was particularly well adapted to the hot, arid climate of southern Texas. In the 1920s when the breed was on the brink of extinction, U.S. Forest Service employees established a protected herd at the Wichita Mountains Wildlife Refuge in Oklahoma, and a small group of ranchers established other small herds in Oklahoma and Texas, including in Texas state parks. It was through the efforts of this small group of people that the breed was kept alive. As American tastes in meat changed, Texas longhorns became economically popular once again.

Today, they are highly valued for their lean meat and their specific climatic adaptation. They are also living genetic repositories—their specific genetic adaptations are now used to help create new breeds of cattle for dealing with future climate change such as those predicted for several parts of the southern United States and elsewhere.

According to data collected by the United Nations’ Food and Agriculture Organization, Texas longhorns are one of over 8,700 breeds of domesticated animals used for food production on the planet today. Most are part of the “big five”: cattle, sheep, chickens, goats, and pigs. Over 8,000 of these breeds are local—recorded in only one country and most of them are specific to particular areas or regions like Texas longhorns, Gulf Coast sheep in Florida and Louisiana, and Mulefoot pigs in Missouri.

Many of these breeds, however, are also vulnerable to extinction—they are not as profitable and farmers focus on a few breeds to maximize products for national and global markets. There are estimates that over 100 livestock breeds have gone extinct in the last 15 years, and29.54% of existing livestock breeds worldwide are at risk of extinction, while for the majority of breeds we lack data on their status, size of population, or likelihood for survival for the future.

Why are local breeds important? They are the result of centuries and even millennia of adaptation to their environments through human management and natural selection pressures. They are living gene banks of biodiversity and have special traits in comparison with industrial livestock—some are resistant to parasites or diseases; feed on different forage; or are highly fertile or long-lived. Others thrive in hot or humid environments such as Gulf Coast sheep that don’t have wool on their bellies, legs, or heads.

Despite many years of research, current information on these breeds is sorely lacking. There is very limited genetic data on most of the economically important animal breeds on the planet, and the pressures of industrialized agriculture are pushing farmers to focus on the few breeds with the current highest economic rewards. But this comes at a cost—today’s industrial farming strategies are not sustainable for an unknown future. Local breeds are living genetic repositories. They are the result of long-term histories and cannot be simply made in a laboratory. They are the future of our food security.

Many species are on the brink of extinction and need conservation help, and many are perhaps more photogenic or emblematic than cows or sheep. However, livestock breeds need this help too if we want to secure genetic diversity in our foods. This conservation doesn’t need to be expensive—dedicated farmers and conservation groups should be financially supported in maintaining local breeds. If the federal government is turning its back on these initiatives, state and local governments need to help fill the gap. Small investments today will pay dividends in the future to keep our food systems resilient.
