How Science-Based Policies Can Transform Agriculture

The Union of Concerned Scientists argues that U.S. agricultural policies currently favor an industrial model that prioritizes corporate profit over health and the environment. The brief highlights a significant disparity in subsidies, noting that corn and soybean growers receive over ten times the support of all fruit and vegetable growers combined. This system is linked to water pollution and high energy consumption, accounting for nearly 16 percent of total U.S. energy use. The authors propose transitioning to agroecology—a science-based approach utilizing crop rotations, cover cropping, and integrated livestock management—to create a more resilient and nutritious food system. Key policy recommendations include increasing investments in local food hubs, providing new incentives for organic production, and requiring conservation standards for farmers receiving federal subsidies.

• U.S. federal subsidies are heavily skewed toward processed-food and animal-feed crops, with corn and soybean growers receiving more than 10 times the subsidies provided to all fruit and vegetable growers combined. In 2010, the USDA paid over $5 billion in subsidies for corn and soybeans alone, while subsidies for fruits and vegetables were only about 7 percent of that amount.
• Industrial agriculture is a primary driver of environmental degradation and energy consumption in the United States. The U.S. Environmental Protection Agency identifies agriculture as the leading source of water pollution in the nation's streams and rivers. Additionally, the industrialized food system is responsible for nearly 16 percent of all energy used in the U.S.
• There is growing consumer demand for sustainable food systems, evidenced by the rapid growth of organic food sales, which reached nearly $29 billion annually and are growing at nearly eight times the rate of the overall U.S. food market. Farmers markets have more than doubled in number since 2002, and locally grown foods contribute nearly $5 billion annually to local economies.
• The Union of Concerned Scientists advocates for the adoption of agroecology, a science-based approach that treats farms as ecosystems. This method includes practices such as longer crop rotations to maintain soil fertility, cover cropping to prevent erosion and reduce fertilizer needs, and raising livestock in close proximity to crops to recycle nutrients and reduce transportation costs.
• To transform the food system, the document recommends specific policy changes via the Farm Bill, including increasing investments in local and regional food systems (such as food hubs and CSAs), creating a safety net for farmers transitioning to diversified practices, and implementing rules that require a minimum level of conservation for any farmer receiving federal subsidies.
