Land degradation debt

We define as environmental debt: (a) the difference between natural forest potential and actual tree cover globally, and aggregated by latitude and by world region, (b) the difference between natural soil erosion and actual soil erosion globally, and aggregated by latitude and by world region, (c) the difference between natural above-ground carbon and actual above-ground carbon globally, and aggregated by latitude and by world region, (d), the difference between natural below-ground carbon and current below-ground (0–30 cm) carbon globally, and aggregated by latitude and by world region.
