USDA Awards Research Grants to Address the Impact of Climate Change on U.S. Agriculture Production
Des Moines, Iowa, April 22, 2014 – Agriculture Secretary Tom Vilsack announced today that USDA's National Institute of Food and Agriculture (NIFA) awarded $6 million to 10 universities to study the effects of climate on agriculture production and develop strategies to provide farmers and ranchers with the solutions they need to supply the nation with quality food. Vilsack made the announcement during remarks at "The Frontier of Climate Change: State and Local Action in the Heartland" conference held at Drake University.
"With longer growing seasons and an increased number of extreme weather events, climate-related changes are increasingly posing new challenges and risks for America's producers," said Vilsack. "Every day, farmers and ranchers see the impact that changes in climate patterns have on their operations, and they are contending with drought, floods or extreme temperatures. The discoveries these grants will lead to will be invaluable for American farmers whose livelihoods directly depend on the nation's land and water resources."
NIFA made the awards through its Agriculture and Food Research Initiative (AFRI) funding opportunity in the Climate Variability and Change challenge area. NIFA's climate work is focused on reducing greenhouse gas emissions and increasing carbon sequestration in agricultural and forest production systems and preparing the nation's agriculture and forests to adapt to changing climates.
The fiscal year 2013 awards announced today include:
- University of Colorado , Boulder, Colo., $900,000 - This study will provide an integrated social and biophysical assessment of vulnerability and adaptation to climate change and variability in the Blue Mountains ecoregion of Oregon.
- Florida International University , Miami, Fla., $250,000 – This project will study the mechanism of Ochratoxin-A toxicity in wine-musts (freshly pressed grape juice for wine making) which is predicted to intensify in winemaking regions because of the increased prevalence of the toxin producing fungi in warmer climates, and create an inexpensive and simple method of detoxification.
- Iowa State University , Ames, Iowa, $550,000 - The goal of this research is to examine factors that either facilitate or hinder climate adaptation, while assessing the role of human-made infrastructure and policies that protect natural resources, grassland and wetlands. .
- Michigan State University , East Lansing, Mich., $975,000 – This project will seek to define the effects of hot and cold temperatures on turkey growth and development and develop management practices to mitigate these effects.
- University of Minnesota , St. Paul, Minn., $25,000 – This is a conference grant to support the National Extension Climate Science Initiative Conference, which will empower Extension professionals and collaborators with the latest in climate science research and delivery methods.
- Montana State University , Bozeman, Mont., $800,000 – This project will determine what effects a climate-induced rise in water temperature will have on rainbow trout gut microbial communities and fish metabolism.
- Cornell University , Ithaca, N.Y., $600,000 – This project will evaluate the resiliency of rice production with increasing climate uncertainty by developing models integrating historical rice yield data at the county and farm level, weather variables, and genotypic parameters.
- Oklahoma State University , Stillwater, Okla., $1,000,000 - The project will provide some of the first climate adaptation tools for beef production systems in the form of water management resources and lead to the development of beef cattle that are adaptable to climate change induced drought.
- Pennsylvania State University , University Park, Pa., $750,000 – This project aims to strengthen farm operators' capacity to manage cropping system's adaptation to climate change by providing real time online decision making tools.
- West Virginia University , Morgantown, W.V., $150,000 – This project will study the effect of climate change on interactions among solitary pollinator bees, bee parasites and crops.
AFRI is NIFA's flagship competitive grant program established under the 2008 Farm Bill and supports work in six priority areas: 1) plant health and production and plant products; 2) animal health and production and animal products; 3) food safety, nutrition and health; 4) renewable energy, natural resources and environment; 5) agriculture systems and technology; and 6) agriculture economics and rural communities.

Impact of climate change on agriculture suggests even greater challenges to the environment, global food supply and public health
A sweeping global research review of the links between climate and agriculture reveals the likelihood of an emergent feedback loop whereby, as climate change puts more pressure on the global food supply, agriculture will, by necessity, adopt practices that may exacerbate its environmental impact. This research, published in Science , includes an extensive evaluation of experts, including from Columbia University Mailman School of Public Health. The paper also identifies new agricultural practices that have the potential to increase efficiency and stabilize our food supply in the decades to come.
The authors point out that greenhouse gas emissions from agriculture are now 18 times higher than they were in the 1960s, accounting for about 30% of global warming. Excess fertilizer left on farm soil is broken down by bacteria to form nitrous oxide, a greenhouse gas that is 300 times more potent than carbon dioxide. Strategic efforts to reduce the warming impact of agriculture while maintaining high yields are essential to both mitigating climate change and protecting our food supply from its impacts.
"It is important to recognize that the impact of agriculture on public health, from pesticide usage to water quality, is almost certainly going to be exacerbated with climate change," said Lewis Ziska, PhD, associate professor of Environmental Health Sciences at the Columbia Mailman School of Public Health and a co-author.
The research found:
- Climate change has broad-ranging impacts on agricultural practices, increasing water use and scarcity, nitrous oxide and methane emissions, soil degradation, nitrogen and phosphorus pollution, pest pressure, pesticide pollution and biodiversity loss.
- Climate-agriculture feedback pathways could dramatically increase agricultural greenhouse gas emissions. Without changes in agriculture, this feedback loop could make it impossible to achieve the Paris Agreement goal of limiting global warming to 1.5 degrees Celsius to 2 degrees Celsius.
- Existing sustainable agricultural practices and technologies, if they are implemented on a wide scale, can greatly reduce agricultural emissions and prevent a feedback loop from developing. To achieve this, governments must work to remove socioeconomic barriers and make climate-resilient solutions accessible to farmers and food producers.
"We need agriculture, but the future of humanity also requires that we reduce agriculture's environmental harms," said co-author David Tilman, a professor at the University of Minnesota College of Biological Sciences. "By evaluating new practices being tried around the world we have identified practices that appear to increase harvests while decreasing environmental harm. Once these new practices are tested and verified, we need a farm bill that pays farmers both for producing food and for improving the environment. Enabling better stewardship has tremendous benefits for all of us."
The researchers looked at all aspects of the relationship between agriculture and climate to determine where new practices are the most effective. While carbon sequestration is currently a priority, an integrated approach that factors in farming efficiency and pollutants like nitrous oxide could deliver much larger climate benefits and a more stable future for agriculture. Practices such as precision fertilizer use and crop rotation can prevent a feedback loop from developing."
The team identified a number of next steps. First and foremost, stakeholders should accelerate the adaptation and cost-reduction of efficient and climate-friendly agriculture. Precision farming, perennial crop integration, agrivoltaics, nitrogen fixation, and novel genome editing are among the emerging techniques that could increase production and efficiency in agriculture while reducing climate change impacts. They recommend further research on climate-agriculture feedback pathways and new technologies like on-farm robots.

Climate Change Impacts on Agriculture and Food Supply
There are over two million farms in the United States, and more than half the nation’s land is used for agricultural production. 1 The number of farms has been slowly declining since the 1930s, 2 though the average farm size has remained about the same since the early 1970s. 3 Agriculture also extends beyond farms. It includes industries such as food service and food manufacturing.
Drought. Since early 2020, the U.S. Southwest has been experiencing one of the most severe long-term droughts of the past 1,200 years. Multiple seasons of record low precipitation and near-record high temperatures were the main triggers of the drought. 37
Wildfires. Some tribal communities are particularly vulnerable to wildfires due to their often-remote locations and lack of firefighting resources and staff. 38 In addition, because wildfire smoke can travel long distances from the source fire, its effects can be far reaching, especially for people with certain medical conditions or who spend long periods of time outside.
Decreased crop yields. Rising temperatures and carbon dioxide concentrations may increase some crop yields, but the yields of major commodity crops (such as corn, rice, and oats) are expected to be lower than they would in a future without climate change. 39
Heat stress. Dairy cows are especially sensitive to heat stress, which can affect their appetite and milk production. In 2010, heat stress lowered annual U.S. dairy production by an estimated $1.2 billion. 40
Soil erosion. Heavy rainfalls can lead to more soil erosion, which is a major environmental threat to sustainable crop production. 41
Agriculture is very sensitive to weather and climate. 4 It also relies heavily on land, water, and other natural resources that climate affects. 5 While climate changes (such as in temperature, precipitation, and frost timing) could lengthen the growing season or allow different crops to be grown in some regions, 6 it will also make agricultural practices more difficult in others.
The effects of climate change on agriculture will depend on the rate and severity of the change, as well as the degree to which farmers and ranchers can adapt. 7 U.S. agriculture already has many practices in place to adapt to a changing climate, including crop rotation and integrated pest management . A good deal of research is also under way to help prepare for a changing climate.

Top Climate Impacts on Agriculture
Agriculture and the economy, environmental justice and equity, what we can do, related resources, the link between agriculture and climate change.
Climate change can affect crops, livestock, soil and water resources, rural communities, and agricultural workers. The agriculture sector also emits greenhouse gases into the atmosphere that contribute to climate change.
Read more about greenhouse gas emissions from agriculture and other sectors on the Basics of Climate Change page.
For a more technical look at emissions from the agriculture sector, take a look at EPA's Greenhouse Gas Emissions Inventory chapter on agriculture activities in the United States .
Learn how the agriculture sector is reducing methane emissions from livestock waste through the AgSTAR program .
Climate change may affect agriculture at both local and regional scales. Key impacts are described in this section.
1. Changes in Agricultural Productivity
Climate change can make conditions better or worse for growing crops in different regions. For example, changes in temperature, rainfall, and frost-free days are leading to longer growing seasons in almost every state. 8 A longer growing season can have both positive and negative impacts for raising food. Some farmers may be able to plant longer-maturing crops or more crop cycles altogether, while others may need to provide more irrigation over a longer, hotter growing season.
Air pollution may also damage crops, plants, and forests. 9 For example, when plants absorb large amounts of ground-level ozone, they experience reduced photosynthesis, slower growth, and higher sensitivity to diseases. 10
Climate change can also increase the threat of wildfires . Wildfires pose major risks to farmlands, grasslands, and rangelands. 11
Temperature and precipitation changes will also very likely expand the occurrence and range of insects, weeds, and diseases. 12 This could lead to a greater need for weed and pest control. 13
Pollination is vital to more than 100 crops grown in the United States. 14 Warmer temperatures and changing precipitation can affect when plants bloom and when pollinators , such as bees and butterflies, come out. 15 If mismatches occur between when plants flower and when pollinators emerge, pollination could decrease. 16
Heat and humidity can also affect the health and productivity of animals raised for meat, milk, and eggs. 17
2. Impacts to Soil and Water Resources
Climate change is expected to increase the frequency of heavy precipitation in the United States, which can harm crops by eroding soil and depleting soil nutrients. 19
Heavy rains can also increase agricultural runoff into oceans, lakes, and streams which can harm water quality. 20 Runoff can carry nutrients, fertilizer, and pesticides into neighboring water bodies.
When coupled with warming water temperatures brought on by climate change, runoff can lead to depleted oxygen levels in water bodies. This is known as hypoxia . Hypoxia can kill fish and shellfish. It can also affect their ability to find food and habitat, which in turn could harm the coastal societies and economies that depend on those ecosystems. 21
Sea level rise and storms also pose threats to coastal agricultural communities. These threats include erosion, agricultural land losses, and saltwater intrusion, which can contaminate water supplies. 22 Climate change is expected to worsen these threats. 23
3. Agricultural Workers Health
Agricultural workers face several climate-related health risks. These include exposures to heat and other extreme weather, more pesticide exposure due to expanded pest presence, disease-carrying pests like mosquitos and ticks, and degraded air quality. 24 Language barriers, lack of health care access, and other factors can compound these risks. 25
- Wildfire smoke
- Pesticide exposure
For more specific examples of climate change impacts in your region, please see the National Climate Assessment .
Agriculture contributed more than $1.53 trillion to the U.S. gross domestic product in 2023. 27 The sector accounts for 10.4 percent of total U.S. employment. 28 These include not only on-farm jobs, but also jobs in food service and other related industries. Food service makes up the largest share of these jobs at 12.7 million. 29
Cattle, corn, dairy products, and soybeans are the top income-producing commodities . 30 The United States is a key exporter of soybeans, other plant products, tree nuts, animal feeds, beef, and veal. 31
Many hired crop farmworkers are foreign-born people from Mexico and Central America. 32 Most hired crop farmworkers are not migrant workers; instead, they work at a single location within 75 miles of their homes. 33 Many hired farmworkers can be more at risk of climate health threats due to social factors, such as language barriers and health care access.
Climate change could affect food security for some households in the country. Most U.S. households are currently food secure . This means that all people in the household have enough food to live active, healthy lives. 34 In 2022, 12.8 percent (17.0 million households) were food insecure. These households faced a lack of resources that resulted in difficulty providing enough food for all their members. U.S. households with above-average food insecurity include those with an income below the poverty threshold, those headed by a single woman, and those with Black or Hispanic owners and lessees. 35
Climate change can also affect food security for some Indigenous peoples in Hawai'i and other U.S.-affiliated Pacific islands. Climate impacts like sea level rise and more intense storms can affect the production of crops like taro, breadfruit, and mango. 36 These crops are often key sources of nutrition and may also have cultural and economic importance.
We can reduce the impact of climate change on agriculture in many ways, including the following:
- Incorporate climate-smart farming methods. Farmers can use climate forecasting tools, plant cover crops, and take other steps to help manage climate-related production threats.
- Join AgSTAR. Livestock producers can get help in recovering methane , a potent greenhouse gas, from biogas created when manure decomposes.
- Reduce runoff. Agricultural producers can strategically apply fertilizers, keep their animals out of streams, and take more actions to reduce nutrient-laden runoff.
- Boost crop resistance. Adopt research-proven ways to reduce the impacts of climate change on crops and livestock , such as reducing pesticide use and improving pollination.
- Prevent food waste. Stretch your dollar and shrink your carbon footprint by planning your shopping trips carefully and properly storing food . Donate nutritious, untouched food to food banks and those in need.
See additional actions you can take, as well as steps that companies can take, on EPA’s What You Can Do About Climate Change page.

Climate change is one of the most pressing challenges facing humanity today. Its effects extend to numerous sectors of society, and agriculture is one of the most vulnerable to its consequences. Changes in weather patterns threaten global crop productivity, giving rise to serious sustainability concerns. Climate change significantly negatively impacts global crop productivity. Research has consistently shown that increased temperatures, climate variability, and extreme events are associated with decreased crop yields, as well as conditions conducive to the spread and proliferation of agricultural pathogens. These effects are of particular concern in regions that are already experiencing adverse climatic conditions, mainly droughts, and floods. This chapter reviews the literature on the influence of climate change on crop productivity worldwide, analyzes the observed effects on agriculture, and explores adaptation and mitigation strategies used to address these challenges.

Global warming is one of the greatest threats to the social development of human beings. It is a typical example of global climate change, and has profoundly affected human production and life in various aspects. As the foundation of human existence, agricultural production is particularly vulnerable to climate change, which has altered environmental factors such as temperature, precipitation ...
Des Moines, Iowa, April 22, 2014 - Agriculture Secretary Tom Vilsack announced today that USDA's National Institute of Food and Agriculture (NIFA) awarded $6 million to 10 universities to study the effects of climate on agriculture production and develop strategies to provide farmers and ranchers with the solutions they need to supply the nation with quality food.
research assistance, and Prabhu Pingali and Rachid Serraj for their leadership in the CGIAR Foresight exercise that motivated this work. ... Climate change impacts on agriculture must be understood in the context of the intertwined systems that affect food security and agricultural trade, including biological, socioeconomic, and political ...
The research found: Climate change has broad-ranging impacts on agricultural practices, increasing water use and scarcity, nitrous oxide and methane emissions, soil degradation, nitrogen and ...
The effects of climate change on agriculture will depend on the rate and severity of the change, as well as the degree to which farmers and ranchers can adapt. 7 U.S. agriculture already has many practices in place to adapt to a changing climate, including crop rotation and integrated pest management. A good deal of research is also under way ...
About 95% of these losses are attributed to weather related incidences, of which cyclones, floods and droughts are the key players and are directly related to climate change. Altogether, the impact of climate change is very comprehensive but its far reaching effects are now clearly visible on agricultural sector, on which relies the food ...
Conducting research on climate change impacts on agriculture requires background and institutional knowledge that is not acquired in graduate economics or applied economics programs. Section 2 addresses this by introducing basic concepts and terminology as well as background information on the various types of weather data and climate models. I ...
In this sense, there is an urgent need for a close global effort to implement carbon policies and technological innovation to mitigate the climate impacts of agriculture. Therefore, this research is a time-noting study to help international policymakers achieve environmental sustainability-oriented policies.
Climate change has the potential to alter agricultural systems, leading to a decrease in crop yields and, thus, food security. Therefore, adaptation strategies and mitigation efforts are needed to help reduce the negative impacts of climate change on agriculture and crop production (Straffelini and Tarolli 2023; Wijerathna-Yapa and Pathirana 2022).
expected climate change.1 Consumers, producers and governments may respond to climate change by, for example, adjusting production technologies, improving institutional capacity or participating in global food systems. Accounting for these adjustments is central to accurately estimating the impact of climate change on agricultural outcomes.
