Focus: the difficult livestock issue
A central topic of most debates on sustainable food systems is the complex role of livestock, meat and dairy. This is due to their connection to many issues of moral and practical concern related to food systems; affecting both humans and the environment, and animal's own interests. The picture is complex. And because different stakeholders bring different worldviews and perspectives, people often disagree about the appropriate role of livestock, meat, and dairy, in sustainable food systems. Yet demand for meat and dairy consumption is expected to grow considerably, and as a result, debates around livestock-related issues are becoming increasingly prominent. Understanding these helps to provide a broader understanding of food systems more generally.

Re-framing the climate change debate in the livestock sector: mitigation and adaptation options
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).

Can ruminants reduce rather than increase agriculture’s carbon footprint in North America?
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.

FAO releases findings of global dairy feed mapping project
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.
