Corresponding author email: [email protected] DOI : 10.5281/zenodo.20531053 Abstract The escalating global population exerts immense pressure on agricultural systems, necessitating innovative strategies to ensure food security. The increasing demand, along with unsustainable agricultural methods and the widespread application of agrochemicals, has resulted in a notable deterioration of soil fertility and overall ecosystem health. Consequently, modern agriculture faces the dual challenge of increasing productivity per unit area sustainably to meet caloric demands and addressing the detrimental impacts of climate change on soil health and agricultural output. Therefore, there exists a pressing necessity to enhance agricultural productivity while concurrently ensuring environmental sustainability. Central to these objectives is the maintenance of an optimal level of organic matter, which is essential for safeguarding the physical, chemical, and biological health of the soil, supporting sustained agricultural output, while simultaneously ensuring ecological balance. Biochar, a stable carbon-rich material produced from organic residues via pyrolysis, emerges as a holistic solution that synergistically integrates these goals. Its application to agricultural soils boosts soil organic carbon stocks, improves nutrient retention, and enhances water-holding capacity—factors crucial for the resilience and productivity of next-generation farming systems. As a long-term carbon sink, biochar supports climate mitigation by sequestering atmospheric CO₂ for centuries and reducing emissions of potent greenhouse gases like methane and nitrous oxide. Unlocking biochar's potential entails collective developments in smart agriculture, such as precision application technology, legislative incentives, and community engagement customized to local conditions. Adopting biochar-based soil carbon management creates a virtuous loop by converting agricultural waste into a regenerative input, restoring agroecosystem health, and contributing to a climate-resilient, sustainable food future. This book chapter dives into the application of biochar in fostering efficient crop and soil carbon management with an eye toward a sustainable future. Key words: Biochar, soil carbon management, sustainable agriculture, soil health.
