Описание: More than 75 % of Earth’s land areas are substantially degraded. Rapid expansion and unsustainable management of croplands and grazing lands is the main driver of land degradation, causing significant loss of biodiversity and ecosystem services (e.g., food security, water purification, energy provision). These drivers are mainly due to the high-consumption lifestyles of the most developed economies, and the rising consumption in developing and emerging economies. In order to halt and reverse the current trends in land degradation, there is an immediate need to enhance national capacities to undertake quantitative assessments and corresponding mapping of their degraded lands. Earth Observations (EO) can play an important role for generating the SDG indicator 15.3.1 (“proportion of land that is degraded over total land area”) as well as complementing or enhancing national official data sources.
