A recent report into global food security, commissioned by the UK government, has called for instant action in order to avert global hunger. The Foresight Report on Food and Farming Futures predicts that, with the world population expected to reach 8.3 billion over the next 20 years, demand for food is set to increase by some 40 percent, fresh water by 30 percent, and energy by up to 50 percent. The study postulates that the conditions are being created for a 'perfect storm' of growing population, climate change and diminishing resources for food production.
