Global assessment of soil carbon in grasslands: From current stock estimates to sequestration potentialFood & Agriculture Org., 14/02/2023 - 76 páginas Soils contribute to the achievement of the UN Sustainable Development Goals through carbon sequestration. By enhancing soil health and fertility, soils can play a crucial role in climate action, land degradation neutrality, and alleviating hunger. The present study provides a spatially explicit report on the state of grassland soils and can be used as a baseline for future work to explore the impacts of livestock management on soil carbon at regional, country and farm levels. Assessing the current state of grassland systems and their potential to sequester carbon in the soil is of key importance to understand the trade-offs between grassland services on food security, biodiversity conservation and climate mitigation. |
