Feeding the World
First broadcast April 2007

Woman and meat in a supermarket

This BBC World Service series investigates the growing but often under-reported challenges facing the world's food supply.

Global Warming, soil erosion and a world population that is set to grow by a further two and half billion in the next 30 years, are just some of the pressures that could undermine the current state of relative abundance.

The BBC's World Affairs correspondent Mark Doyle assesses which outcome will prevail and the factors that will decide it. He discovers what policies need to be put in place now to ensure the world can feed itself in the future.

Part Two: The Taste of Excess

Mark Doyle investigates the way we eat food and its effect on the global food supply.

The emergence of supermarkets and global supply chains has led to a far greater variety in the types and range of food available to most of us. But it's also, some say, distorted the market in the types of food we eat.

Today, sugars and meat are far cheaper than they were 50 years ago, and they are being heavily sold in the range of fast and processed foods that are widely available. Critics argue this has played a large part in the doubling over that past decade of overweight and obese people.

Furthermore, it has also promoted an appetite for food that is very inefficient to produce, and if as expected emerging economies like India and China start to demand the same meat-heavy diets consumed in the west, the global food supply may struggle to cope.
