Session 5 - Addressing climate and biodiversity challenges: Nature-based solutions for risk management
Nature-based solutions (NbS) are actions aimed at protecting, managing, and restoring ecosystems to address societal challenges while providing benefits for both human well-being and biodiversity. They offer essential tools for climate change mitigation and adaptation, contributing to carbon sequestration, biodiversity conservation, and resilience against climate hazards. The business case for NbS is strengthened by their ability to meet multiple objectives, reduce costs, and align with global climate and biodiversity policy agendas.
