For example, one of the best ways to mitigate climate change is to create sustainable food systems based on sustainable agriculture. Sustainable agriculture provides a potential solution to enable agricultural systems to feed a growing population within the changing environmental conditions. [ 6 ]
Sustainable yield is the amount of a resource that humans can harvest without over-harvesting or damaging a potentially renewable resource. [1]In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time.

These climatic events are predicted to increase in the future and are expected to have significant consequences to the agriculture sector. [201] This would have a negative influence on food prices, food security, and land-use decisions. [202] Yields from rainfed agriculture in some African countries could be reduced by up to 50% by 2020. [201]
A study in India reported that SRI practices resulted in a yield increase of 41% compared to conventional practices. [23] The Food and Agriculture Organization of the United Nations (FAO) found similar effects on production. For example, in Cambodia they found that farms that introduced SRI practices were producing double the amount of rice per ...
Meat is obtained through a variety of methods, including organic farming, free-range farming, intensive livestock production, and subsistence agriculture. The livestock sector also includes wool, egg and dairy production, the livestock used for tillage, and fish farming. Animal agriculture is a significant contributor to greenhouse gas emissions.
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 ).
In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. [1] Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well. [2]
Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult. Therefore, agricultural productivity is usually measured as the market value of the final output ...
