Ⅰ. Necessity and Purpose of the Research
oThe reduction of greenhouse gas emissions to realize carbon neutrality (Net Zero) can be achieved by reducing emissions from energy and non-energy sectors, while simultaneously expanding carbon absorption sources and increasing absorption and storage.
oDeveloped countries such as the European Union (EU) and international agreements such as the Convention on Biological Diversity emphasize the conservation and restoration of ecosystems and biodiversity, which is a nature-based solution (NbS), to respond to the climate crisis.
oIt is impossible to estimate the carbon absorption of Korea’s entire nature and ecosystem, and it is difficult to establish a policy to expand Korea’s unique carbon sinks. Accordingly, in order to prepare a successful carbon sink expansion policy based on domestic nature and ecosystem, it is necessary to identify the carbon absorption status of soil and agricultural ecosystems and evaluate their potential.
Ⅱ. Soil Carbon and Agriculture
o Soil biodiversity and carbon
ㅇ It is generally known that about 50-60% of soil organic matter consists of soil organic carbon (SOC). The amount of soil organic matter is estimated by measuring SOC and applying a conversion factor.
ㅇ Europe recognizes that the main factors responsible for the loss of soil biodiversity are the ecosystem level, including land use change, overuse and exploitation, climate and hydrological changes, and the level of biological species and genes in the soil.
ㅇ Soil carbon storage is one of the important ecosystem services resulting from interaction
