How does sustainable food production meet the demands of the global population explosion

Ensuring a sustainable supply of food for the world's fast growing population is a major challenge. Food production is one of the key areas that require action, alongside issues of food consumption, nutrition and food security.

It is estimated that by 2050 the world's population will reach 9.1 billion (34% higher than today). Food production will need to increase by 70% to feed the larger and most likely more urban population.1 More food will have to be produced using less land. In addition water and energy will become limiting factors.

Added to the challenge is that sustainable food products need to be nutrient-dense to allow people to have a diverse diet that contains a balanced and adequate combination of energy and nutrients to support good health.
