Reducing Enteric Methane for improving food security and livelihoods

For an estimated 800 million resource-poor farmers, ruminant production is a pathway out of poverty. However, ruminants are a large contributor to greenhouse gases (GHG) emissions, in particular enteric methane (CH4).

Farming systems that are more productive generally have higher total CH4 emissions but much lower emissions per unit of product (also referred to as ‘emissions intensity (Ei)’ ... [read more]

What is enteric methane?

Naturally occurring methane is generated by anaerobic fermentation, where bacteria break down organic matter producing hydrogen (H2), carbon dioxide (CO2) and methane (CH4). This process naturally occurs in the digestive system of domesticated and wild ruminants, natural wetlands, and rice patties. In ruminants, methane is produced mostly by enteric fermentation where microbes decompose and ferment plant materials, such as celluloses, fiber, starches, and sugars, in their digestive tract or rumen.
