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 ...
Traditional rice cultivation is the second biggest agricultural methane source after livestock, with a near-term warming impact equivalent to the carbon dioxide emissions from all aviation. [73] Government involvement in agricultural policy is limited due to the high demand for agricultural products like corn, wheat, and milk. [ 74 ]
The "global land squeeze" for agricultural land [178] also has impacts on food security. [179] Likewise, effects of climate change on agriculture can result in lower crop yields and nutritional quality due to for example drought, heat waves and flooding as well as increases in water scarcity, [180] [181] pests and plant diseases.
According to 2014 report by the International Food Policy Research Institute, agricultural technologies will have the greatest impact on food production if adopted in combination with each other. Using a model that assessed how eleven technologies could impact agricultural productivity, food security and trade by 2050, the International Food ...
Organic farming typically reduces some environmental impact relative to conventional farming, but the scale of reduction can be difficult to quantify and varies depending on farming methods. In some cases, reducing food waste and dietary changes might provide greater benefits. [43]
The vulnerability of agriculture to climatic change is strongly dependent on the responses taken by humans to moderate the effects of climate change. [ 6 ] Changes in crop and livestock viability are forcing the farmers to find better choices of crops and animals, capable of adaption to temperature changes and water availability.
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]
Food loss and waste is a major part of the impact of agriculture on climate change (it amounts to 3.3 billion tons of CO 2 e emissions annually [5] [6]) and other environmental issues, such as land use, water use and loss of biodiversity.
