Land Degradation Neutrality Fund The LDN Fund invests in projects which reduce or reverse land degradation and thereby contribute to ‘Land Degradation Neutrality’. The LDN Fund is co-promoted by the Global Mechanism of the United Nations Convention to Combat Desertification (UNCCD) and Mirova. It is a public-private partnership using public money to increase private sector investment in sustainable development. The fund invests in sustainable agriculture, forestry and other land uses globally. The Fund was launched at the UNCCD’s COP 13 in China in 2017.
