Established in 1994, the United Nations Convention to Combat Desertification (UNCCD) is the sole legally binding international agreement linking environment and development to sustainable land management. The Convention seeks to support countries in addressing Desertification, Land Degradation, and Drought (www.unccd.int). The G20 (or Group of Twenty) is the annual international forum for the governments of 19 industrialized countries and the European Union. The G20 Leaders' Declaration, issued on Sunday, 22 November 2020, launched a \"Global Initiative on Reducing Land Degradation and Enhancing Conservation of Terrestrial Habitats\". Building on existing initiatives and on a voluntary basis, the G20 countries share the ambition to achieve a 50 percent reduction in the amount of degraded land by 2040. The G20 Global Land Initiative (G20 GLI) focuses on building capacity, engaging the private sector, empowering civil society and showcasing success. Engaging with all stakeholders in land restoration efforts is crucial to promote inclusivity and sustainability as well as the ownership and empowerment of local communities and stakeholders, who can bring unique perspectives, knowledge, resources and solutions to the table and ensure their needs and rights are respected and accounted for in the process.
