Abstract

This study addresses the critical alteration of the global carbon cycle, a cornerstone of planetary homeostasis, intensified by anthropogenic activities since the Industrial Revolution. Within this context, the pedosphere emerges as a carbon reservoir of significant magnitude, its integrity being crucial for soil fertility, ecosystem resilience, food security, and global climate regulation. Consequently, the soil's capacity to sequester atmospheric carbon represents a promising avenue for climate change mitigation. The primary objective is to investigate the multifaceted interactions among soil carbon, climate change, and human activities. This is achieved through an analysis of recent scientific literature from peer-reviewed sources, aiming to identify strategies that enhance agroecosystem resilience and mitigate greenhouse gas emissions. Principal findings indicate that, while the soil constitutes a vast reservoir of both soil organic carbon (SOC) and soil inorganic carbon (SIC), unsustainable practices—including deforestation, intensive tillage, and improper management—convert it from a carbon sink to an emission source. Climate projections suggest an exacerbation of these pressures. Nevertheless, the adoption of practices such as conservation agriculture, agroforestry systems, biochar application, and the restoration of degraded ecosystems can significantly augment SOC, improve edaphic health, and reduce emissions. Global initiatives, such as RECSOIL, and national policies, like Brazil's ABC+ Plan, exemplify efforts to reverse this trend and promote climate-smart, regenerative soil management. However, challenges persist in quantification, monitoring, and overcoming socioeconomic barriers to widespread implementation.
