To what extent do GHG emissions, AMR and animal welfare of livestock production vary with yield?

Food production has more impact on land use, biodiversity and greenhouse gas (GHG) emissions than any other human activity. In particular, rapidly rising demand for animal products is widely considered to be unsustainable, leading to calls for “sustainable intensification”.

Livestock intensification has increased production and profits but many worry that such high-intensity techniques bring with them other important environmental and health costs.

Research Interests

 I am interested in investigating the limits of livestock intensification, including the trade-offs between intensification and animal welfare, antimicrobial use, and environmental externalities.
