In a Warming World We Can’t Keep Depending on the Same Few Crops

Good OpEd on the homogenisation of global food systems…

The homogenisation of global food systems means that any fast-food outlet must depend on a long, complex and increasingly vulnerable supply chain to source products whose ingredients are derived from a tiny range of plant and animal species. While there are an estimated 30,000 edible plant species, just three (wheat, rice and maize) now account for more than 60% of the calories consumed by 7 billion people across the world.

If we disturb the supply chains or the productivity of these major crops we are in trouble – wherever we live. Precisely because of their global significance and the consequences of their failure, virtually all our agricultural research, funding and promotion focuses exclusively on squeezing more out of these major crops grown as monocultures.
