RT null T1 Nature-based Infrastructure: How Natural Infrastructure Solutions Can Address Sustainable Development Challenges and the Triple Planetary Crisis - Executive Summary A1 United Nations Environment Programme, A2 Haggis, Robyn A2 Palmer, Rowan A2 Beck, Maximilian A2 Fuldauer, Lena A2 Hall, Jim A2 Mutyaba, Robert A2 Price, Joseph A2 Seddon, Nathalie A2 Stratton-Short, Samantha A2 Thacker, Scott A2 Tores, Carol YR 2023 FD 2023-11 LK https://wedocs.unep.org/handle/20.500.11822/44172 UL https://wedocs.unep.org/handle/20.500.11822/44172 NO This executive summary outlines how nature-based infrastructure can contribute to addressing sustainable development, climate change and biodiversity challenges through integration with built infrastructure systems. It presents a framework describing five functions through which nature-based infrastructure delivers, enhances and protects infrastructure services while providing workforce and wider social, environmental and economic benefits. The document assesses its contribution to the Sustainable Development Goals and climate mitigation and adaptation objectives, examines investment opportunities and financing gaps, and identifies barriers to wider implementation, including data limitations, governance, costs and stakeholder coordination. It concludes with recommendations for embedding nature-based infrastructure into planning, investment, monitoring, capacity development and decision-making to support sustainable infrastructure systems.
