Restoration of degraded land is essential for keeping global climate promises. Actions that prevent, halt and reverse degradation can deliver one-third of the mitigation that is needed by 2030 to keep global temperatures below 2°C. Ecosystem supports all life on earth including people. Protection and revival of ecosystem can help not only to combat climate change, but also to end poverty and prevent the collapse of biodiversity. Under the backdrop of the UN Decade on Ecosystem Restoration (2021-2030) and the 26th UN Climate Change Conference of the Parties (COP26), UNOSD will organize a side event which focuses on accelerating ecosystem restoration, climate action and sustainable development through green deals. The event will incorporate presentations from the countries on their experiences, best practices, and lessons learned on Green Deal as a means to accelerate nature crisis responses and realize the SDGs.
