![]() ![]() Wildfires pose major risks to farmlands, grasslands, and rangelands. 10Ĭlimate change can also increase the threat of wildfires. 9 For example, when plants absorb large amounts of ground-level ozone, they experience reduced photosynthesis, slower growth, and higher sensitivity to diseases. Air pollution may also damage crops, plants, and forests. 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. 8 A longer growing season can have both positive and negative impacts for raising food. For example, changes in temperature, rainfall, and frost-free days are leading to longer growing seasons in almost every state. Changes in Agricultural ProductivityĬlimate change can make conditions better or worse for growing crops in different regions. ![]() Key impacts are described in this section. Top Climate Impacts on AgricultureĬlimate change may affect agriculture at both local and regional scales. 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. Read more about greenhouse gas emissions on the Basics of Climate Change page. However, the agriculture sector also emits greenhouse gases into the atmosphere that contribute to climate change. Learn more about climate change and agriculture:Ĭlimate change can affect crops, livestock, soil and water resources, rural communities, and agricultural workers. A good deal of research is also under way to help prepare for a changing climate. agriculture already has many practices in place to adapt to a changing climate, including crop rotation and integrated pest management. 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. 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. 4 It also relies heavily on land, water, and other natural resources that climate affects. 41Īgriculture is very sensitive to weather and climate. Heavy rainfalls can lead to more soil erosion, which is a major environmental threat to sustainable crop production. ![]()
