A considerable rise in food costs has been evident over the past years. While empty storage facilities are no longer a problem in industrial countries, over 800 million people worldwide suffer from chronic malnutrition. Cereal stocks for global supply are sufficient for only 40 days. By 2050, the demand for food is expected to double.
At the same time, arable land is being used for non-food products such as bio fuels. We can be sure that the food supply will be even more difficult to guarantee in the future (European Parliament 2009). The population of Europe is covered by food produced in Europe, though domestic produce is complemented by importing specific items like coffee, cocoa and fruit from other countries.
