World food security, globalisation and animal farming: unlocking dominant paradigms of animal health science.

This paper presents a critical review of intensive animal farming in the light of past and present global crises, reflecting the fragility of its foundations, its unsustainability and its inability to ensure world food security. A central argument of this paper is that intensive animal farming promotes industrial efficiency, commodity production and the availability of cheap food at the expense of farmed animals, the environment and society. This paper begins by briefly examining the history of world food security and explores the role assigned to animal farming, animal health and public health in this context. It then reviews changing perceptions of world food security during various periods of global instability and their implications for animal farming and animal health and welfare. At the same time, the paper seeks to identify what has so far been missing in discourses around world food security and animal farming, and discusses how these gaps shape and are shaped by specific scientific thinking on animal health and well-being. With the recent exponential growth of aquaculture, the authors' objectives are to examine animal health practices in farming and to understand how animal health science could effectively, in the long term, help animal farming, and in particular aquaculture, to contribute to global food security.
