Animal Feeding / Climate Change / Livestock / Research

Feeding less food-competing feedstuffs to livestock and global food system sustainability

Increasing efficiency in livestock production and reducing the share of animal products in human consumption are two strategies to curb the adverse environmental impacts of the livestock sector.

A recent article models the impacts and constraints of a third strategy in which livestock feed components that compete with direct human food crop production are reduced. In this scenario, animals are fed only from grassland and by-products from food production.

They show that such a strategy focusing on feed components which do not compete with direct human food consumption offers a viable complement to strategies focusing on increased efficiency in production or reduced shares of animal products in consumption.
