The amount of '''greenhouse gas emissions from agriculture''' is significant: The agriculture, forestry and land use sectors contribute between 13% and 21% of global [[greenhouse gas emissions]]. Emissions come from ''direct'' greenhouse gas emissions (for example from [[Rice|rice production]] and [[livestock]] farming). And from ''indirect'' emissions. With regards to direct emissions, [[nitrous oxide]] and [[methane]] makeup over half of total greenhouse gas emissions from agriculture.

A 2023 review emphasizes that emissions from agricultural soils are shaped by factors such as soil type, climate, and management practices. It also highlights several mitigation strategies, including conservation tillage, precision agriculture, improved water use, and the application of biochar, that can reduce emissions and enhance soil carbon storage. Indirect emissions on the other hand come from the conversion of non-agricultural land such as [[forest]]s into agricultural land. Furthermore, there is also [[fossil fuel]] consumption for transport and [[fertilizer]] production. For example, the [[Haber process|manufacture]] and use of [[nitrogen fertilizer]] contributes around 5% of all global greenhouse gas emissions. [[Environmental impacts of animal agriculture|Livestock farming]] is a major source of greenhouse gas emissions. At the same time, [[Effects of climate change on livestock|livestock farming is affected by climate change]].
