Land degradation is a serious environmental issue that jeopardizes worldwide agricultural output, water supplies, and ecological stability. According to the United Nations Convention to Combat Desertification (UNCCD), 20 to 40 percent of the total global land area is degraded, affecting over half of the world’s population who rely on croplands, drylands, wetlands, forests, and grasslands. This situation is dire for India, as a 2025 scientific assessment published in Nature emphasizes the urgent need to intervene in Gully Erosion in 77 Indian Districts, with eastern and southern India accounting for 70% of the total. This intervention is critical for India to attain the United Nations’ target of land degradation neutrality (LDN) by 2030.

Gully erosion, a severe form of soil degradation, causes deeply incised channels in the landscape, harming land productivity and ecological balance. The research emphasizes that gully erosion is a key impediment to India’s objective to attain land degradation neutrality. It affects agricultural production and water availability and even prompts entire village abandonment in the worst-affected regions. Addressing this issue requires a comprehensive approach that involves mapping impacted regions, developing appropriate land management rules, and reformulating soil erosion prevention programs at the state and district levels.

Understanding Gully Erosion and Its Impact in India

Gully erosion is a major cause of global land degradation, with significant implications for India. It emerges as three distinct geomorphic features: gully networks, badlands, and denuded hill slopes. Due to Gully Erosion in 77 Indian Districts, while western India is primarily impacted by badlands, eastern India suffers from more severe gully erosion, which poses a more significant challenge to land sustainability efforts.

Prolonged gully erosion creates badlands, which are extensively degraded landscapes that are difficult to restore. The research emphasizes that the Indian badlands lead to diminishing agricultural output, increased water stress, and protracted droughts, frequently resulting in forced migration. Given how gully systems contribute to land degradation, current attempts to map India’s badlands have expanded to include a more complete study of them.

This work uses high-resolution satellite data (1-metre resolution) to generate the first thorough regional inventory of gully erosion in India. This mapping endeavor aims to examine the location, extent, and management conditions of gullied lands, evaluate the level of gully management, and estimate the total affected land area across states and districts. The ultimate goal is to identify priority regions that require intervention and argue for legislative reforms designed to manage gully erosion within India’s LDN framework.

Lead author Anindya Majhi emphasized the importance of gully erosion in eastern India, disputing the widely held idea that Indian badlands represent the worst-case scenario. While badlands remain a primary environmental concern, the paper sees gully erosion in eastern India as a more formidable barrier to achieving land degradation neutrality. Furthermore, the authors emphasize that incorrect badland reclamation procedures can have serious environmental, ecological, and socioeconomic effects, necessitating a balanced and region-specific rehabilitation strategy.

Need for Policy Reforms and Effective Land Management

The report identified Gully Erosion in 77 Indian Districts as high or very high management priority areas for tackling it. Jharkhand, Chhattisgarh, Madhya Pradesh, and Rajasthan have the highest levels of degradation. Notably, Jharkhand is the most badly afflicted state, highlighting the importance of tailored intervention efforts.

To counteract the growing issue of land degradation, India needs a firm land management policy that distinguishes between badlands and gullies while addressing the societal and environmental consequences. The study emphasises that gully erosion rates are projected to climb in the coming years due to increased rainfall intensity caused by climate change. As a result, a proactive approach is required to avoid future deterioration.

The authors argue for using their spatial inventory and district-level gully erosion maps to help policymakers, environmental agencies, and local governments manage gullied areas effectively. The key recommendations include:

• Comprehensive Land Restoration Programs: Use large-scale afforestation, contour bunding, and soil conservation techniques to stabilize degraded areas and prevent further deterioration.
• Community-Based Soil Conservation Initiatives: Involve local communities in soil conservation efforts through training programs, incentive-based restoration projects, and sustainable land-use practices.
• Integration of Technology in Land Management: Use modern satellite images, GIS mapping, and artificial intelligence to monitor gully formation and deploy targeted erosion management techniques.
• Legislative and Policy Reforms: To reduce erosion risks and strengthen national and state policies on soil protection, land use planning, and sustainable agriculture can be employed.
• Climate Resilience Measures: Implement climate adaptation techniques to combat the growing danger of extreme weather events exacerbating soil erosion.

Conclusion

The report’s conclusions serve as a critical call to action for India to incorporate gully erosion management into its overall environmental sustainability goals. By using a science-driven approach, encouraging intergovernmental collaboration, and executing targeted interventions, India may make substantial progress toward reaching land degradation neutrality by 2030. Addressing gully erosion is critical for maintaining agricultural output in the country, protecting water resources, minimising the effects of climate change, and sustaining long-term livelihoods for millions of people who rely on land resources.
