Join Nathalie Seddon and Cameron Hepburn as they discuss the need for increased investment combined with rigorous evaluation of activities undertaken, using metrics which consider the complex, long-term benefits that nature-based solutions provide. Nature-based solutions (NbS) can contribute to the fight against climate change up to the end of our century. But the world must invest now in nature-based solutions that are ecologically sound, socially equitable, and designed to deliver multiple benefits to society over a century or more. Properly managed, the protection, restoration and sustainable management of our working lands could benefit many generations to come. While solutions such as community-led restoration and protection of mangroves, kelp forests, wetlands, grasslands and forests, bringing trees into working lands and nature into cities can bring multiple benefits from storing carbon and protecting us from extreme events, to supporting biodiversity and providing jobs and livelihoods, how can we engage governments, businesses and local communities in these solutions to ensure their success? The Economics of Biodiversity: The Dasgupta Review states that relative to other interventions, Nature-based solutions have the potential to be cost-effective and provide multiple benefits beyond climate adaptation and disaster risk reduction. So how can these economic evaluations for each solution be derived?
