With the global warming and more abnormal climate, understanding the relationship between climate change and agriculture is crucial to understanding the role of agriculture in promoting and mitigating global warming. Carbon sequestration, the reduction of fossil fuel dependent resources and the use of renewable energy all make organic agriculture a pioneer in reducing energy consumption and reducing the negative impact of energy emissions. The management norms provided by organic agriculture can help farmers adapt to climate change by strengthening agricultural ecosystems and carrying out diversified production of crops and livestock, while building a knowledge base to prevent and respond to climate change in the most effective way.
FAO promotes organic agriculture as an alternative that can improve the efficiency of renewable resources and optimize the nutrient and energy cycle of agro ecosystems. Life cycle assessment shows that, based on the production area, the emissions of conventional production systems are always higher than those of organic production systems. Soil nitrogen oxides and methane emissions from arable land or dry peatland used as pasture can be avoided through organic management methods. A number of field tests carried out around the world show that compared with inorganic fertilizers, organic fertilizers can continuously increase soil organic carbon, so they can store a large amount of carbon dioxide in the atmosphere in the soil. Organic agriculture can reduce greenhouse gas emissions in crop production, promote carbon sequestration, and biodiversity and other environmental services can provide more benefits. All these factors make organic agriculture a farming method with many advantages and great potential in mitigating and adapting to climate change.
