Reviving soils

Globally an estimated 20 to 60 million hectares of land in developing countries are acquired by foreign companies and investors. This so-called “land grabbing” has taken place for various reasons. The most obvious one is the hunger for maximising profit. The devastating effects on deforestation for the expansion of biofuels, sugar cane, palm oil and soya bean for animal feed are well known. A less visible reason is to secure food by those who have seen large areas of land in their home country become unsuitable for farming. This is particularly the case for India and China, where the Green Revolution model of industrial farming has been promoted for decades. Today, due to this industrial model of farming about a third of China’s total cultivated area is seriously eroded by wind and water. According to Dave Montgomery in his book Growing a Revolution, half of the soil carbon in the midwestern USA has been lost. At EU level, soil erosion affects over 12 million hectares of land – about 7.2% of the total agricultural land – and leads to €1.25 billion loss in crop productivity.e
