UN publishes first Global Report on Black Earth


The Food and Agriculture Organization of the United Nations (FAO) has released its first global report on black soils being depleted due to the climate crisis, the Biodiversity and land use are now more at risk than ever before.

Schwarzerden zeichnen sich durch einen starken dunkel gefärbten Bodenhorizont aus, der reich an organischer Substanz ist. Die größte Fläche der Schwarzerde wird in Russland (327 Millionen Hektar), Kasachstan (108 Millionen Hektar), China (50 Millionen Hektar), Argentinien (40 Millionen Hektar), der Mongolei (39 Millionen Hektar), der Ukraine (34 Millionen Hektar), den USA (31 million hectares), Colombia (25 million hectares), Canada (13 million hectares) and Mexico (12 million hectares).

Due to black soil's inherent fertility, it is considered necessary for the global food supply. The black soils have another important property: they are of paramount importance for mitigating and adapting to climate change impacts, they contain 8,2% of the world's soil organic carbon (SoC) reserves and can provide 10% of the global SoC sequestration potential. The Ultimate SoC offers many benefits for people and the environment and is one of the most cost-effective options to adapt to and mitigate the effects of climate change, as well as to combat desertification, land degradation and lack of food security.

As the FAO report shows, this "black treasure" is endangered. Due to land-use changes (about 31% of black soil is processed worldwide), unstable management methods and overuse of agrochemicals, most black soil has already lost at least half of its SOC stock and suffers from erosion processes, nutrient imbalances, soil biodiversity and Vegetation.
