National Implementation and Current Status of Nature-based Solutions (NbS) to Address Climate Change Issues

Nature-based Solutions (NbS) for climate change represent one of today's most pressing research areas. This session brings together global NbS experts to share current developments, cutting-edge research, and practical examples while exploring key challenges, opportunities, and future directions in the field.

Nature-based Solutions (officially defined at the United Nations Environment Assembly (UNEA) in 2022) harness natural processes to tackle environmental challenges while delivering economic, social, and ecological benefits. These cost-effective interventions integrate diverse natural systems into urban and rural landscapes, building resilience through locally-adapted, resource-efficient approaches

At COP26 (2021, UK), Nature-based Solutions for climate change took center stage, showcasing initiatives in forest conservation, wetland restoration, and urban greening. Discussions highlighted NbS potential for climate mitigation, community collaboration, developing country support, and international funding mechanisms. The UK government committed £3 billion to NbS investments over five years.

NbS offers an effective approach not only for climate change and biodiversity loss, but also for complex challenges including strengthening local resilience, promoting social and economic development, and improving health and welfare.
However, there still are several issues to solve on NbS, such as implementation to the regions of various geographical backgrounds, institution building and fundraising.

This session brings together experts from diverse backgrounds who research and implement NbS to share current developments, latest findings, and practical case studies. Through interactive discussions with participants, the seminar explores challenges and opportunities for domestic and international expansion of NbS whilst considering future directions collaboratively.
