Beef Feeding Organizations in Semi-Arid Rangelands: Greenhouse Gas Discharges

Abstract

Ramón Reiné

The beef industry plays a crucial role in Argentina's economy, and the central semi-arid rangelands of the country are a significant production area. However, beef production is associated with greenhouse gas (GHG) emissions, which contribute to climate change. Understanding the dynamics of GHG emissions in beef grazing systems is essential for implementing sustainable practices and mitigating their environmental impact. This article explores the factors influencing GHG emissions in beef grazing systems in central Argentina's semi-arid rangelands and discusses potential strategies to reduce emissions. Enteric fermentation, primarily carried out by rumen microbes in cattle, is a significant source of GHG emissions. Ruminants produce methane (CH₄), a potent greenhouse gas, during the digestion process. Central Argentina's semi-arid rangelands are characterized by extensive grazing systems, where cattle primarily feed on natural pastures. The quality of forage and grazing management practices can influence enteric methane emissions.
