This research article provides a new quantitative analysis of data on global feed use and feed use efficiency by livestock, in order to help shed light on livestock’s role in food security.

This report by Compassion for World Farming discusses the potential effects of a reduction in meat consumption in relation to the difference between ruminants such as cows and monogastrics such as pigs and poultry.

In a 2013 TED talk entitled ‘How to fight desertification and reverse climate change’ the Zimbabwean ecologist, Allan Savory, claimed that the ‘holistic management’ grazing management method that he has developed and promoted over 40 years, could stop global desertification and reduce atmospheric carbon dioxide to preindustrial levels, within a few decades.

This review article provides a summary of the multiple environmental and societal costs and benefits of livestock production. Homing in on climate change, it reviews the range of GHG mitigation options that have been proposed both on the supply side (actions that potentially reduce emissions per unit of production, or absolute emissions, considering both changes in practice and in policy) and those on the demand side (e.g. reductions in meat consumption, waste reduction).

As methane produced by ruminants is a potent greenhouse gas (GHG), many researchers and organisations have pointed to the necessity of reducing ruminant stocks around the world. In this study, the authors argue that with the right crop and grazing management, ruminants might not only reduce overall GHG emissions, but could, in fact, facilitate increases in soil carbon, and reduce environmental damage related to current cropping practices.

This report commissioned by the Committee on World Food Security (CFS) and written by its High Level Panel of Experts for Food Security and Nutrition (HLPE) focuses on sustainable agricultural development for food security and nutrition, specifically in relation to livestock.

The International Dairy Federation (IDF), the UN’s Food and Agriculture Organization (FAO), and the IFCN Dairy Research Network (IFCN) have collaborated on an extensive study on international dairy feeding systems to explore how differences within these systems for dairy cows, water buffaloes, sheep, and goats and between large and smallholders can affect a range of issues - from the nutritional content of the milk to the level of GHG emissions involved in the production process. Each of the three organizations had differing stakes in the research.

This study investigates specifically how camels compare to other ruminants in terms of emissions and they find that they release less methane.

The Food and Agriculture Organization of the UN (FAO) has released a report on technical options for the mitigation of non-carbon dioxide greenhouse gas (GHG) emissions livestock production. The report, titled 'Mitigation of Greenhouse Gas Emissions in Livestock Production: A Review of Technical Options for non-CO2 Emissions,' provides a review of over 900 publications focusing on feeding, manure management, breeding and animal husbandry strategies (including the use of rbST and animal genetics) to reduce emissions of methane and nitrous oxide nitrous oxide.
