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 ...
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.

About 77% of the mainland U.S. is abnormally dry, and almost half of the country is experiencing drought, according to the U.S. Drought Monitor. The spatial pattern of the dry conditions varies ...
Agricultural waste are plant residues from agriculture. These waste streams originate from arable land and horticulture. Agricultural waste are all parts of crops that are not used for human or animal food. Crop residues consist mainly of stems, branches (in pruning), and leaves. [1] It is estimated that, on average, 80% of the plant of such ...
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.
A traditional, cold Michigan winter is a key to how certain vital state crops grow, and how invasive species are held back. Mild Michigan winters could have consequences for crops, gardens ...
The use of GMO crop plants engineered for herbicide resistance can also indirectly increase the amount of agricultural pollution associated with herbicide use. For example, the increased use of herbicide in herbicide-resistant corn fields in the mid-western United States is decreasing the amount of milkweeds available for monarch butterfly larvae.
The United States Agency for International Development's (USAID) global hunger and food security initiative, the Feed the Future project, is addressing food loss and waste. By addressing food loss and waste, greenhouse gas emission mitigation is also addressed. By only focusing on dairy systems of 20 value chains in 12 countries, food loss and ...
