News and events News UN Decade on Ecosystem Restoration The United Nations General Assembly have declared 2021 – 2030 the UN Decade on Ecosystem Restoration. It is estimated that restoration could remove up to 26 gigatons of greenhouse gases from the atmosphere. The UN Environment and Food and Agriculture Organisation (FAO) will lead the implementation. The UN Decade on Ecosystem Restoration aims to massively scale up the restoration of degraded and destroyed ecosystems as a proven measure to fight the climate crisis and enhance food security, water supply and biodiversity. The degradation of land and marine ecosystems undermines the well-being of 3.2 billion people and costs about 10 per cent of the annual global gross product in loss of species and ecosystems services. Key ecosystems that deliver numerous services essential to food and agriculture, including supply of freshwater, protection against hazards and provision of habitat for species such as fish and pollinators, are declining rapidly. The Decade, a global call to action, will draw together political support, scientific research and financial muscle to massively scale up restoration from successful pilot initiatives to areas of millions of hectares. Research shows that more than two billion hectares of the world’s deforested and degraded landscapes offer potential for restoration.
