How can agroecology contribute to achieving net zero emission?

Achieving a net zero greenhouse gas (GHG) emissions by 2050 is the only option to keep the global temperature increase below 1.5°C. To achieve this, global efforts are seriously required to reduce over a half of current GHG emissions. Food systems indicate all the sectors and processes involved in production, consumption, and disposal of food. Globally, food systems are currently responsible for a third of anthropogenic GHG emissions and food-system GHG emissions will increase furthermore due to increasing population and food demands, especially in developing countries. Therefore, it is critically required to reduce food-system GHG emissions. Agroecology is the application of ecological concepts and principles to the design and management of sustainable agroecosystems. In recent years, agroecology and its practices have been well recognised to enhance food security and protect environment and biodiversity in agroecosystems. Also, an increasing number of studies have found that they have potential to mitigate food-system GHG emissions. Among various principles of agroecology, most recognised and representative principles were 1) diversity, 2) conservation & recycling, 3) integration, and 4) circulation. However, there is a critical lack of comprehensive understanding about potentials of agroecology for mitigating GHG emissions in food systems since most studies have focused on identifying GHG mitigation with a specific practice in agricultural production. This study will i) identify principles and practices of agroecology for mitigating food-system GHG, ii) synthesize food-system GHG mitigation potentials of agroecological practices, iii) estimate global GHG mitigation by adopting agroecology, and iv) identify research gaps and suggestions for further studies.
