How to feed the world in 2050
Policy options from the Commission on Sustainable Agriculture and Climate Change to allow the food system to operate safely and resiliently within planetary limits.



To achieve food security in a changing climate, the global community must operate within three limits:
  • the quantity of food that can be produced under a given climate;
  • the quantity needed by a growing and changing population; and,
  • the effect of food production on the climate

At present the planet operates outside that safe space, as witnessed by the enormous number of people who are undernourished.

If current trends in population growth, diets, crop yields and climate change continue, the world will still be outside this 'safe operating space' in 2050.

Humanity must urgently work to enlarge the safe space and also move the planet into the safe space.
