Around the world, governments and communities are harnessing the power of nature to manage rising climate risks. Mangroves are restored to reduce storm surges, wetlands rehabilitated to absorb floodwaters, urban trees planted to cool neighborhoods, and upland forests protected to stabilize slopes and protect drinking water sources.

Despite the growing recognition of NBS for their wide‑ranging social, economic, and environmental benefits as well as for their transformative role in building climate‑resilient economies, one critical aspect is often missing: The policies that make them happen.
To address this, the World Bank’s GFDRR is launching its new publication, Unlocking Nature for Disaster Resilience: A Policy Guide to Enable Nature-Based Solutions, which offers a practical roadmap to support governments and World Bank teams shape national and local policies to unlock, scale, and sustain NBS.
Why Policies Matter
Global investment in NBS is rising. Between 2012 and 2024, the World Bank financed approximately 250 NBS investment projects for climate resilience, totaling $12 billion. These projects have rehabilitated 4.6 million hectares of ecosystems and benefited more than 28 million people.
Yet public and private investment needs to grow substantially if countries are to move beyond pilot projects and embed NBS as standard, sector‑wide practice to strengthen resilience and meet international climate commitments.
The barriers? Outdated regulations, siloed sector policies, weak incentives, insufficient enforcement, and the simple reality that in many sectors, policies still favor gray infrastructure by default. Public policy is a key lever for scaling up NBS — together with other levers such as financing and institutional capacity. However, the policy reforms needed to shift practice are still largely missing.
This guide aims to shift the paradigm. It shows how well-designed policies can enable NBS, turning isolated projects into systemic change. Deliberate policy choices can:
This flexible three‑pronged approach enables countries to tailor reforms to their specific contexts, raising ambition for NBS upscaling while carefully balancing potential tradeoffs.
A New Policy Agenda
To provide a set of practical tools for policy reforms, the guide breaks down key policy instruments countries can use across all levels of government and across key sectors.

Every sector has the potential to integrate and scale NBS through policy reforms. The guide focuses on six policy areas most impactful for disaster and climate resilience: disaster risk reduction, climate change, environment and biodiversity, water, agriculture and forestry, and building, land use and urban planning. It also highlights opportunities in the transport, tourism, energy, and extractives sectors, which are priority development areas for the World Bank and where NBS are poised to play an expanding role. The following excerpts offer a snapshot of the insights and guidance explored in the publication.
Turning Policy into Resilience
Countries stand at a crossroads. They can continue to invest solely in traditional gray infrastructure or they can adopt policies that enable ecosystems shape resilient societies and economies.
This guide equips governments, World Bank teams, and other practitioners with what is needed to take the next step: practical policy instruments that promote nature at scale and strengthen resilience across sectors, cities, and countries.
