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.

Intercropping is a natural agricultural practice that often improves the overall health of the soil and plants, increases crop yield, and is sustainable. [ 158 ] One of the most significant aspects of indigenous sustainable agriculture is their traditional ecological knowledge of harvesting.
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]
The concept of maximum sustainable yield is not always easy to apply in practice. Estimation problems arise due to poor assumptions in some models and lack of reliability of the data. [8] [24] Biologists, for example, do not always have enough data to make a clear determination of the population's size and growth rate. Calculating the point at ...
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.
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 ...
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 ).
The agricultural sector accounts for around 24% of anthropogenic emissions. Unlike other sectors that emit greenhouse gases, agriculture and forestry have the potential to mitigate climate change by reducing or removing greenhouse gas emissions, for example by reforestation and landscape restoration.
