Real estate development, Infrastructure development, Industrialisation, and also climate change continuously reduce the amount of available farmland worldwide. Even more important: relative to the growing global population, the available arable land per capita has almost decreased by half in the past 50 years. In the same time, yields per hectare have increased by almost 100 per cent in the most fertile regions of the world, but climate change is about to induce substantial losses of harvests in traditionally fertile regions, e.g. Southern Europe. Global warming will further push agricultural production to moderate climate zones.
