We've been living through times of plenty in recent decades, but no more. World grain supplies are low, there's just forty days' worth in stock and the long-term future looks bleak. Our demand for foods predicted to rise 50% by 2030. The statistics are startling. The worlds population is set to explode from over 6 billion now to 9 billion by 2050.


The increase is mainly in the developing world. In countries like China and India, an economic boom is increasing their wealth and dramatically altering the traditional diet. New western habits are taking hold, the McDonald's wave becoming a familiar sight in unexpected places. More meat and dairy products require more land and water. All the ingredients are there for a future food crisis. And its the first priority of the UKs new chief science adviser.


"The pessimistic scenario, is, this problem is not recognized. This, the increase in productivity that's required. A 50% increase in food production and getting on for 50% in energy production. If thats not met, then you are going to get very very large amount, increases in prices and potential food ferments and real problems, / an inflation of food inflation, in, throughout the world."


The changing climate is part of the problem. Scenes like these in Australia in the last few years could become more common with harvests badly hit. Its estimated global warming can bring us 16% fall in food production by 2020. Biofuels are seen as part of the solution, a greener alternative to fossil fuels. But that's using up land badly needed to grow food. Now some say what's needed is a new Agricultural Revolution to boost food production.


Agriculture has been out of fashion in many science communities. And out of that came a drastic underinvestment. And the world was eating its, and living off the knowledge created a generation ago.


No one suggesting our packs, supermarket shelves will ever be empty. But the world of food is changing fast. Urgent action may be needed now to prevent global scarcity in future.

We’ve been living through times of plenty in recent decades, but no more. While grains of lives are low, they have just forty days worth in stock and the long-term future looks bleak. Our demand for food is predicted to rise 50% by 2030. The statistics are startling. The world’s population is said to explode from over 6 billion now to 9 billion by 2050. The increases may lean in the developing world in countries like China and India. An economic boom is increasing their wealth and dramatically altering the traditional diet. New restaurant habits are taking hold, the McDonald’s reign becoming a familiar sign in unexpected places. More meat and dairy products require more land and water. All the ingredients are there for a future food crisis. And it’s the first priority of the UK’s new Chief Science Adviser. "The pessimistic scenario, is, this problem is not recognized, This, the increase in productivity is required. A 50% increase in food production and getting on for 50% in energy production. If that’s not mad, then you are going to get very very large amount, increases in prices and potential food ferments and real problems, an inflation, a food inflation throughout the world." The changing climate is part of the problem. Scenes like these in Australia in the last two years could become more common with harvests badly hit. It’s estimated global warming can bring us 16% fall in food production by 2020. Wild fields are seen as part of the solution, a greener alternative to fossil fields. But that’s using up land badly needed to grow food. Now some say what’s needed is a new agricultural revolution to boost food production. “Agriculture has been out of fashion in many science communities. And out of that came a drastic underinvestment. And the world was eating its, and leaving off the knowledge created a generation ago.” No one suggesting our packs, super market sales will ever be empty. But the world of food is changing fast. Urgent action may be needed now to prevent a global scarcity in the future. Christine McGourty, BBC.
