Greenhouse gas emissions from agriculture: Difference between revisions

Livestock activities also contribute disproportionately to land-use effects, since crops such as [[Maize|corn]] and [[alfalfa]] are cultivated to feed the animals.

In 2010, [[enteric fermentation]] accounted for 43% of the total greenhouse gas emissions from all agricultural activity in the world.<ref>Food and Agriculture Organization of the United Nations (2013) [http://www.fao.org/docrep/018/i3107e/i3107e00.htm "FAO STATISTICAL YEARBOOK 2013 World Food and Agriculture"]. See data in Table 49.</ref> The meat from ruminants has a higher carbon equivalent footprint than other meats or vegetarian sources of protein based on a global meta-analysis of lifecycle assessment studies. Small ruminants such as sheep and goats contribute approximately 475 million tons of carbon dioxide equivalent to GHG emissions, which constitutes around 6.5% of world agriculture sector emissions. Methane production by animals, principally ruminants, makes up an estimated 15-20% of global production of methane.

Worldwide, livestock production occupies 70% of all land used for agriculture or 30% of the land surface of the Earth. The global [[food system]] is responsible for one-third of the global anthropogenic [[Greenhouse gas emissions|GHG emissions]], of which meat accounts for nearly 60%.
