Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2]
Sustainable agriculture provides a potential solution to enable agricultural systems to feed a growing population within the changing environmental conditions. [6] Besides sustainable farming practices, dietary shifts to sustainable diets are an intertwined way to substantially reduce environmental impacts.
[211] [212] A study summarising a number of impact studies of climate change on agriculture in Latin America indicated that wheat is expected to decrease in Brazil, Argentina and Uruguay. [212] Livestock, which is the main agricultural product for parts of Argentina, Uruguay, southern Brazil, Venezuela , and Colombia is likely to be reduced.
Agricultural productivity (including e.g. reliability of yields) is an important component of food security [144] and increasing it sustainably (e.g. with high efficiency in terms of environmental impacts) could be a major way to decrease negative environmental impacts, such as by decreasing the amount of land needed for farming or reducing ...
Extremes matter because agricultural productivity is driven largely by environmental conditions during critical threshold periods of crop and livestock development. Improved assessment of climate change effects on agricultural productivity requires greater integration of extreme events into crop and economic models.
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]
Climate-smart agriculture (CSA) (or climate resilient agriculture) is a set of farming methods that has three main objectives with regards to climate change. [ 1 ] [ 2 ] Firstly, they use adaptation methods to respond to the effects of climate change on agriculture (this also builds resilience to climate change ).
Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands, estuaries, and groundwater. Pollutants from farming include sediments, nutrients, pathogens, pesticides, metals, and salts. [1] Animal agriculture has an outsized impact on pollutants that enter the environment.
