There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding. [5]
The USDA Economic Research Services is predicting a less than 2% rise in food prices in the near future, but if the food in question is used to feed livestock, a domino effect of increasing prices ...
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. [73] Crop plants exposed to drought stress suffer from reductions in leaf water potential and transpiration rate.
High wheat prices caused by the drought have discouraged farmers from investing in alternative drought-tolerant crops. [87] The United States Drought Monitor observed "extreme drought" conditions in much of the eastern half of Massachusetts, southeastern New Hampshire and the southern part of Maine in September 2016. [88]
It can reduce plant abundance and affect the amount of forage vegetation for grazing animals. Drought and overgrazing during rapid growth periods of a plant’s life also lead to less growth the ...
The environmental impact of agriculture involves impacts on a variety of different factors: the soil, water, the air, animal and soil variety, people, plants, and the food itself. Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss ...
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.
Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering. [4] From an evolutionary perspective, the type of mycorrhizal associations formed in the roots of plants can determine how fast plants can adapt to drought.
