The global food supply foundations are shaky. Soil erodes, water resources and biodiversity diminish. Climate change increases the risk of crop failure.

At the same time, demand for food rises dramatically. An increasing consumption of meat requires more and more land for growing corn and soybean. A lot of land is used for production of renewable raw materials. More than half the nutrients are lost on the way from farm to plate or they end up in the trash.

After the crisis of 2008 financial markets hailed land as the new gold standard. Banks and investment funds buy large areas of agricultural land. The World Bank estimates that nearly 40% of global cropland is on the shopping list of new green investors.

The world food falls further out of balance. The gap between food production and demand will open even more. Asia and Africa are faced with an explosive population development. More and more people flee from the countryside to slums surrounding big cities.
