HA plays an important role in soil carbon accumulation, which is essential for the greenhouse effection to slow down the temperature going up. Also it important for polluted soil and water recovery.
The soil is essential for addressing climate change.
However, due to poor farming practices, industrialization and urbanization, one-third of the world’s soil has been degraded, not only limiting agricultural production but also releasing 13.3 billion tons of CO2. Therefore, improving soil carbon stocks has become an urgent plan.
A published book named “Increase Soil Carbon Storage to Realize Paris Climate Commitment” in 2018, cited that:
Carbon in Soils to Meet Paris Climate Pledges, an article calling on countries need to increase soil carbon stocks in response to climate change and food security issues:
- Prevent soil carbon loss by protecting peatlands, managing forests, limiting grazing, and applying green manure.
- Planting nitrogen-fixing plants, reducing fertilizer, adding crop residues or manure.
- Monitoring, Tracking reports, Assessment, and verification of the impact of interventions.
- Using advanced instruments such as portable infrared spectrometers, satellite images & using automatic programs to monitor carbon storage changes.
- Test the effectiveness by deploying pilot networks, spot checks, field surveys, remote sensing monitoring, and development of computer models.
- Increasing public awareness as well as encourage the public to improve soil organic carbon storage capacity.
- Coordinate land sustainable management policies and climate change political framework.
- Incorporate soil carbon targets into national emission reduction commitments to help countries achieve Paris climate commitments and prevent land degradation.
- Promote actions by integrating soil carbon into carbon tax or carbon emissions trading system, distributing soil health cards to farmers, and then creating global investment funds to promote the improvement of it.
The “Thousands of Thousand Initiatives” is an action plan launched at the COP21 Paris Climate Summit in 2015 to “Enhance soil carbon content by 4% per year”. Sequestration to play a key role in agricultural soils in climate change and food security
