10 D+C Vol.42.2015:2 Food production, biodiversity and climate protection depend on healthy soils, but this important resource is being eroded. Moreover, access to land is unequally distributed among users worldwide. Soils are the basis of life. Without fer­ tile land the loss of biodiversity can­ not be stopped, global warming cannot be halted, and the right of every individual to adequate food cannot be fulfilled. Never­ theless, 24 billion tonnes of fertile soil are lost every year because of misuse, accord­ ing to the Soil Atlas 2015. The publishers – the Heinrich Böll Foundation and the Institute for Advanced Sustainability Studies (IASS) in Potsdam – call for fairer and more sustainable land policies and for more responsible con­ sumer habits. “We are using the world’s soils as if they were inexhaustible, contin­ ually withdrawing from an account, but never paying in,” the introduction of the most recent edition states. Soils are of vital importance not only for food production. They also filter rain­ water, thus providing clean drinking wa­ ter, and contribute to regulating the cli­ mate. The earth’s ground is the world’s largest carbon sink: it stores more carbon than all the world’s forests put together. Loss of quality The Soil Atlas identifies various reasons for the increasing loss of land and soils. Cities and roads are spreading, heavy agri­ cultural machinery compacts the ground, and pesticides and ferti­ lisers decimate soil organ­ isms. In addition, there is wind and water erosion. Unfair distribution of land worldwide com­ pounds the problems. Ac­ cording to the study, the average European annually relies on land use amount­ ing to 1.3 hectares that are needed to produce all of the food and other prod­ ucts he or she consumes. That is six times more than is available to Bangla­ deshis on average. “Given the critical food situation in many countries, this flies in the face of justice and is also ecologically unten­ able,” says Barbara Unmüs­ sig, the president of the Heinrich Böll Foundation. Klaus Töpfer, the executive director of the IASS, points out that Germany’s de­ pendence on intensive land use beyond its borders has an adverse effect on global ecosystems. “That’s why we must use the new UN Sustainable Development Goals to improve soil pro­ tection in Germany.” Bulk commodities are shipped from where they are grown to the rich countries where they are processed and consumed. Land shortages are thus outsourced to­ day: land has become another flexible fac­ tor of production. According to the Soil Atlas, almost 60 % of the land area that serves European demand lies outside the EU. “Most of that land contributes to our intensive meat industry, for which we im­ port huge quantities of feed from coun­ tries in the Global South. As a result, small farmers and medium-sized operations are increasingly losing their land and thus the basis for their livelihoods and food secu­ rity,” says Unmüssig. Land conflicts ­increase The demand of food, fodder and biofuels is growing everywhere, and the value of land is rising accordingly. Various user groups compete with each other. The Soil Atlas quotes Klaus Deininger, a World Bank economist, with the statement that land grabbing affects between 10 and 30 % of the arable land worldwide. This phenomenon has a wide range of politi­ cal implications. Examples include Ken­ ya, where disputes over land between the members of different tribes contributed to the bloody post-election riots of 2007/2008, and Madagascar, where the government tried to sell 1.3 million hec­ tares of arable land to Daewoo, a South Korean conglomerate. The resulting un­ rest led to a coup in 2009. The authors of the study identify three trends that dominate how we use land today: We are crossing several global ecologi­ cal limits simultaneously, and at in­ creasing speed. Despite economic growth, billions of people are left without a fair share of land resources. We know all this, yet we lack policies to correct the situation. Development policymakers should fo­ cus more on this issue, as the Soil Atlas points out. 2015 could mark the begin­ ning: It is the International Year of Soils.
