Abstract
This study estimates the contribution of earthworms to global agricultural production by analyzing earthworm abundance, soil properties, crop yields, and earthworm-yield responses. Findings indicate that earthworms contribute to approximately 6.5% of global grain production and 2.3% of legume production, totaling over 140 million metric tons annually. This contribution is particularly significant in the global South, reaching 10% of grain production in Sub-Saharan Africa and 8% in Latin America and the Caribbean. The study suggests that supporting earthworm populations through agroecological practices can contribute to sustainable agricultural goals.
