Revitalizing Soil Health through Regenerative Agriculture: History, Principles, Practices and Challenges

Soil health is the foundation of sustainable agricultural systems, influencing crop productivity, water dynamics, carbon sequestration and ecosystem stability. However, modern industrial agriculture has led to widespread soil degradation, erosion, loss of organic matter and declining microbial diversity. Regenerative agriculture (RA) is a holistic farming approach designed to restore soil health, enhance biodiversity and improve ecosystem resilience. As conventional agricultural practices have led to widespread soil degradation, climate change and biodiversity loss, RA offers a nature-based solution to mitigate these impacts while ensuring long-term food security. RA prioritizes key principles such as minimal soil disturbance, cover cropping, crop diversification, composting, rotational grazing and reduced synthetic inputs, all of which contribute to carbon sequestration, water conservation and soil fertility improvement. Despite its numerous benefits, the large-scale adoption of RA faces challenges, including economic barriers, knowledge gaps and policy constraints. Transitioning to RA often involves short-term yield declines and financial burdens, while the lack of standardized certification limits market access. However, research indicates that RA can significantly enhance soil organic matter, increase drought resilience and improve farm profitability over time. Future efforts should focus on research funding, policy incentives and farmer education programs to accelerate RA adoption. By integrating science-backed regenerative practices into agricultural systems, RA has the potential to combat climate change, restore degraded lands and create a more resilient and sustainable food system for future generations. This review explores the key principles, techniques, benefits, challenges and future directions of RA in revitalizing soil health and ensuring long-term agricultural sustainability.
