Moving livestock toward a more sustainable future

The Ecosystems Services and Management (ESM) Environmental Resources and Developments (ERD) research group upgraded the livestock module of the IIASA model GLOBIOM to make it the state-of-the-art global economic model in terms of livestock sector representation.

Livestock are the source of 33% of the protein in human diets, utilize 30% of the global land area, and are responsible for about 12% of all anthropogenic greenhouse gas (GHG) emissions. Researchers in ERD collaborated with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia to update GLOBIOM to make it the state-of-the-art global economic model in terms of livestock sector representation [1].

Two studies investigating the GHG mitigation potential of, on the one hand, livestock systems transitions at global scale [2], and on the other hand, grassland intensification in Brazil [3], were published in the Proceedings of the National Academy of Sciences of the USA.

The role of the livestock sector in the sustainable development of Africa was the focus of a report commissioned by the US Agency for International Development, co-funded by the AnimalChange project of the European Union’s Seventh Framework Programme, and produced by the office of the Special Representative of the UN Secretary General for Food Security. This report represents direct input in the policy process regarding livestock sector in African countries [4].

Finally, the potential of livestock sector to buffer climate change impacts and contribute to the agricultural sector adaptation was produced for the Food and Agriculture Programme of the UN [5].
