The Biodiversity Finance Gap—the difference between the financial resources needed to conserve and sustainably manage biodiversity, and the funds currently available—is one of the most pressing challenges in global conservation. Estimates suggest that closing this gap requires hundreds of billions of dollars annually. Although no less than US$143 billion is spent on biodiversity every year globally, this is far below the estimated US$824 billion needed to protect and restore nature.
