Crops

The effects of climate change on crop production will vary by region, and will largely be a factor of impacts on resources important to agricultural production, such as soil and water.

Soils provide a wide variety of ecosystem services, including regulating carbon through sequestration and providing a structure to support crop plants. Erosion of soil, the primary source for soil particles to leave agricultural fields, may increase in certain areas of the U.S. due to climate change. Some areas of the country will experience less rainfall, causing soils to dry out. Combined with higher winds, this may lead to higher rates of wind erosion. Other areas may experience more intensive rainstorms, which can increase erosion rates by washing out stream banks, for example. Other factors affecting soil erosion that may increase or decrease due to climate change include changing irrigation needs, snowmelt patterns, soil erodibility, conservation practices, and topography.

Please join us for a two-day event geared towards all things agriculture and water-use efficiency. We will share understanding about how climate change will affect irrigated/rain fed specialty crops in the Northeast and how water-use efficiency practices can be improved. Co-…

The USDA Midwest Climate Hub and the Indiana State Climate Office at Purdue University will provide a 1.5 day workshop on regional research, management and monitoring needs with an emphasis on herbicide/pesticide drift issues.  This workshop will provide “science-to-services”…

Increasing humidity and precipitation and rising extreme temperatures are having negative impacts across the Midwest. Integrating climate adaptation into planning processes can help build adaptive capacity to increase climate resilience. The U.S. Climate Resiliency Toolkit for…

Maine is a state known for its long, cold winters and short growing season, but changes in climate are disrupting this norm. Many growers around the state have already started to experience the trend towards longer growing seasons. This includes slightly warmer summers and…

Salinity and Salinization Impacts Coastal forests and farmlands in parts of the Southeast are being negatively affected by saltwater intrusion and salinization. Elevated salinity levels cause crop yield declines, coastal forest loss, salt-tolerant invasive species takeover,…

Saltwater flooding, due to sea level rise and more frequent and intense storm events, has become an increasing problem for farmers near coastal lands. (Bay Journal, March 2019). The Mid-Atlantic States of the eastern U.S. are being especially affected by coastal flooding due to…

Many Rhode Island farmers plant winter cover crops, such as winter rye (Secale cereale). The plants help to reduce soil erosion, improve soil quality, and provide other benefits. Summer cover crops traditionally have not been used in Rhode Island because of the short summer…

One third of all of our food comes from pollinated crops.  Because increasing temperatures impact both plants and the pollinators they rely on, climate change poses a dual threat to crop production. Shifts in dates when plants flower or pollinators are present could…
