Nature-based Solutions (NbS) is an approach to addressing environmental and development challenges through protecting, maintaining, and enhancing ecosystem services. As part of CMP’s Collaborative Learning Initiatives, Australian NGO TierraMar researched how effectively NbS can benefit people and the environment. They interviewed people working in the NbS space, including many CMP members. Among other recommendations, the report highlights the need for more coordination and collaboration between NbS practitioners and donors.
