Desertification and drought continue to threaten ecosystems, food systems, and livelihoods around the world. As climate pressures rise, the need to protect and restore our land becomes increasingly urgent. The 2025 theme, “Restore Land, Unlock Opportunities”, shines a light on the vast potential that lies in healthy, resilient landscapes—from boosting food security to driving economic growth and environmental sustainability.

World Day to Combat Desertification and Drought calls on all of us—researchers, policymakers, and communities—to work together toward land restoration and drought resilience. Scientific research plays a critical role in shaping real-world solutions and inspiring action where it is needed most.

To support this global effort, MDPI is proud to feature selected articles from Atmosphere, Biology, Climate, Conservation, Ecologies, Environments, Hydrology, Land and Sustainability. These contributions explore key issues around land degradation, water scarcity, and climate change, helping to unlock the knowledge and innovation needed for a more sustainable future.
