Belynda Petrie (OneWorld) moderated the session, and introduced it by outlining some of the key questions the session sought to answer, including: How do we demystify NbS? How do we finance NbS projects at scale? And through all this, how do we ensure socially equitable and inclusive outcomes?
Kicking off the demystification segment, Gareth James Lloyd (UNEP-DHI Centre on Water and Environment), outlined a systems approach that simplified NbS and used examples to emphasise the layered benefits of NbS. In Tanzania, the protection of key water sources is leading to greater climate resilience, restored forests, and financial co-benefits for the local people. Eight challenges and barriers arose for discussion and resolution.
Christine Colvin (WWF), discussed best practices for NbS, highlighting the need for localised solutions. Such solutions are typically context-specific, community-driven and sensitive to the unique climate challenges of the area. Importantly, NbS metrics cannot be scaled up in the same way as carbon metrics. Localised solutions also benefit from the global shift towards prioritising inland, strategic water sources.
