The role of soil carbon in natural climate solutions | Nature ...
2020年3月16日 · Soil carbon comprises 9% of the mitigation potential of forests, 72% for wetlands and 47% for agriculture and grasslands. Soil carbon is important to land-based efforts to prevent carbon...
Soil-Based Carbon Sequestration - MIT Climate Portal
2021年4月15日 · Soil-based carbon sequestration is a way to remove CO2 from the air and store it somewhere it can’t easily escape: in soils, which store carbon in the form of broken-down plant matter.
Soil Carbon: Introduction, Importance, Status, Threat, and …
2018年1月1日 · Soils represent a massive stock of terrestrial organic carbon (C) and act both as a buffer against atmospheric CO 2 increase and as a potential sink for additional C depending on the balance between photosynthesis, the respiration of decomposer organisms, and stabilization of C in soil.
Soil Carbon Storage | Learn Science at Scitable - Nature
Soil carbon storage is a vital ecosystem service, resulting from interactions of ecological processes. Human activities affecting these processes can lead to carbon loss or improved storage.
Soil Carbon Sequestration Impacts on Global Climate Change …
2004年6月11日 · Soil Carbon Sequestration and Global Food Security. Global hotspots of soil degradation with a high priority for soil restoration and C sequestration include SSA, central and south Asia, China, the Andean region, the Caribbean, and the acid savannas of South America.
Towards a global-scale soil climate mitigation strategy
2020年10月27日 · Sustainable soil carbon sequestration practices need to be rapidly scaled up and implemented to contribute to climate change mitigation. We highlight that the major potential for carbon ...
Harnessing soil carbon sequestration to address climate change ...
2024年3月1日 · By rejuvenating depleted soils, enhancing biomass production, purifying surface and groundwater, and offsetting CO 2 emissions from fossil fuels, soil carbon sequestration can serve as a holistic and effective approach for mitigating current climatic changes.
How climate change may threaten soil’s ability to capture carbon
2023年5月11日 · Roots release exudates — organic carbon compounds — that interact with bacteria, fungi, and other soil elements to make its nutrients more accessible to the plant.
Grassland soil carbon sequestration: Current understanding
2022年8月4日 · Grasslands store approximately one third of the global terrestrial carbon stocks and can act as an important soil carbon sink. Recent studies show that plant diversity increases soil organic carbon (SOC) storage by elevating carbon inputs to belowground biomass and promoting microbial necromass contribution to SOC storage.
Soil captures most carbon and is key in climate battle
2021年8月17日 · The world’s soils capture more carbon than biomass and the atmosphere combined. So increasing their ability to store carbon could have a big impact on climate change. Scientists say improving soil health could lead to an extra 2 billion tonnes of CO2 being sequestered by 2030.
