Evidence on the impacts of long-term cassava-based conservation agriculture systems on soil organic carbon and greenhouse gas emissions in Cambodia highlighted that Conservation Agriculture (CA) systems representing credible strategies for the Royal Government of Cambodia to fulfill international conventions (NDC, UNCCD, LDN).
In this experiment, the SOC sequestration rates under Conservation agriculture systems ranged from +0.70 to +1.07 tons C/ha/yr. This accumulation offsets global warming potential (GWP100), at a 100-year time scale[1], by removing -2.58 to -3.94 tons CO2-e/ha/yr from the atmosphere by storing it as SOC stock. In comparison, Conventional agriculture removed only -0.52 tons CO 2 -e/ha/yr, which was about 4 times lower than CA systems.
In addition, CA systems could also contribute to better farming practices for better products, adding values to the agricultural commodities as “Green Climate Products”.
