Greening the Future: Regenerative Agriculture for the Climate Crisis

Résumé

The agriculture sector encounters the dual challenge of ensuring food security for the growing world population while mitigating its significant contribution to greenhouse gas (GHG) emissions. Regenerative agriculture offers a system-wide approach intended to address this predicament by transforming farming from a carbon source to a significant carbon sink. Regenerative agriculture (RA) can be a promising strategy that focuses on replenishing soil health, structure, and biodiversity lost to degradation, mainly through practices that augment carbon sequestration. In this review, the current understanding of agriculture's contribution to climate change, the principles and practices of RA, and its potential for mitigation are integrated from various literature sources. The essence of regenerative agriculture is the enhancement of soil organic carbon (SOC) through practices that reinforce natural carbon capture and storage mechanisms. The major principles include reducing soil disturbance, maximizing crop diversity, sustaining living roots in the soil, covering the soil throughout the year, and integrating livestock. These practices aid in preserving soil structure (reduces carbon flux), continuous carbon capture through photosynthesis and provisioning of organic matter to the soil web. In addition, this review analyses methodologies for the natural fixation and long-term carbon sequestration. These includes the application of biochar, a soil amendment which helps in reduction of nitrous oxide emissions, cultivation of soil microbial communities (nitrogen fixing bacteria in root nodules of legumes – energy consuming utilizing more carbon from the plants) and promoting arbuscular mycorrhizal fungi (AMF) which improves binding of soil aggregates (ensuring long-term storage). In addition, this review also examines the scope of emerging scientific interventions in regenerative agriculture such as data-driven precision regenerative agriculture, remote sensing, use of sensors and monitoring, using robotics and automation, all which enables farmers in decision making, reducing reliance in manual labor, as well as identifying areas of concern, and optimize management practices. Incorporating practices like no-till farming, cover cropping and rotational grazing, regenerative agriculture offers a scientifically sound pathway to reduce agricultural emissions, regenerate soil health and actively sequester atmospheric carbon. These methods position it as a crucial solution in the global effort against climate change.
