The Silent Disappearance of Earthworms: A Looming Crisis for Agriculture
Year: 2025
Type: article
Abstract: Earthworms are soil-dwelling invertebrates that hold a unique place in the animal kingdom and are often regarded as “superheroes of the soil.” They play a vital role in improving soil fertility by enhancing aeration, water infiltration, and nutrient recycling, while also reducing the risk of pests and diseases. By consuming organic matter such as plant residues and animal waste, they produce nutrient-rich castings that improve soil health and crop productivity. In addition, earthworms act as natural bio-remediators by accumulating heavy metals from the soil and are an essential link in the food chain, serving as prey for many animals. However, in recent decades, earthworm populations have shown a marked decline. Studies suggest that in some regions populations have dropped by nearly one-third, mainly due to human activities (Barnes et al., 2023). Major causes include excessive use of pesticides and fertilizers, intensive tillage, soil acidification, habitat destruction, and climate change. This decline poses a serious threat to sustainable agriculture. To conserve earthworms, farmers and organizations must adopt eco-friendly measures such as integrated pest management, reduced tillage, vermicomposting, organic amendments, and awareness programs. Protecting earthworm diversity is essential for soil fertility, ecosystem balance, and future food security.
