Changing climate will have both beneficial and harmful effects on farming, but the net effect is unknown. Longer frost-free growing seasons and higher concentrations of atmospheric carbon dioxide would increase yields for many crops during an average year, notably soybeans.
A farmstead in Perry Township, Berks County, Pennsylvania.. Agriculture is a major industry in the U.S. commonwealth of Pennsylvania. [1] As of the most recent United States Census of Agriculture conducted in 2017, there were 53,157 farms in Pennsylvania, covering an area of 7,278,668 acres (2,945,572 hectares) with an average size of 137 acres (55 hectares) per farm.

The effect of increased levels of atmospheric carbon dioxide on the nutritional quality of plants is not limited only to the above-mentioned crop categories and nutrients. A 2014 meta-analysis has shown that crops and wild plants exposed to elevated carbon dioxide levels at various latitudes have lower density of several minerals such as ...
Heavy rain over the winter eased the drought in the West, but now the middle of the country is extraordinarily dry. “It comes across the Mississippi River and then just disappears,” Shane, 47 ...
Crop yield is also negatively effected by drought stress, the reduction in crop yield results from a decrease in photosynthetic rate, changes in leaf development, and altered allocation of resources all due to drought stress. [72] Crop plants exposed to drought stress suffer from reductions in leaf water potential and transpiration rate.
Resistance to drought is a quantitative trait, with a complex phenotype, often confounded by plant phenology. Breeding for drought resistance is further complicated since several types of abiotic stress, such as high temperatures, high irradiance, and nutrient toxicities or deficiencies can challenge crop plants simultaneously.
Drought stress will impact all of the state's 1,600 farmers and a third of the state's 250,000 acres of crawfish ponds. Josh Trahan, a crawfish farmer , depends on the business to sustain himself.
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
