Environmental and societal impact
The other strand of my research is the consumption side, the role of big agri-food business, and how this impacts society and the environment.
Changes to global diet have major impacts across the world's poorer regions. For example, in Peru, every family used to grow and eat quinoa: it was the staple food. But now, it's exported to richer countries like the UK, and is no longer affordable for indigenous populations.
Thailand is a big producer of pork and chicken meat. This had led to vast forest clearances on high ground to accommodate maize grown as animal feed. This is big business, yet farmers get little in return. After harvests, they have little choice but to burn the stubble to clear the land. The smoke settles in the valley, and becomes a serious respiratory problem for many elderly and young.
