The Coastal Risk Index Is
The Platform For Assessing
Coastal Resilience
The Coastal Risk Index – the CRI – harnesses the power of data to enable financial institutions, investors, insurers, and policymakers to better assess coastal risk and improve decision-making in the climate crisis.
Better Data
Better Data
The CRI provides the foundation for better understanding coastal risks, enabling more informed decisions about building resilience in coastal communities. It goes beyond physical flood risk and economics to include social drivers and incorporate the crucial role of nature.
The CRI is an open-source platform providing a detailed set of global flood maps, using hydrodynamic models, to understand current and future coastal flood risk and the flood reduction benefits of natural habitats. Social vulnerability data highlights where reefs and mangroves are critical to reducing risk for climate vulnerable coastal communities.

Outcomes
Better Outcomes
The CRI provides data on the benefits of resilient ecosystems to climate vulnerable coastal communities. This data supports decision-makers in integrating Nature-based Solutions into tools that minimise risk, build resilient communities, and restore ecosystems.
The Coastal Risk Index provides a detailed way to assess coastal flooding in the context of climate change, modelling flood hazard and storm surge in current conditions and in possible future climate scenarios.
The following map shows the CRI’s data on the impact of losing mangrove protection (on the left), as the extent and depth of flooding increases if mangroves are not present (on the right). By quantifying the value of reef and mangrove ecosystems for their flood resilience benefits, the Index can help catalyse their restoration and protection across the world.
About visualization
These visualisations map the future without (left) and with (right) mangroves present to demonstrate the importance of coastal habitats for reducing risks. The data for this map represents a timeframe of 2030 and a storm return period of 100 years. Darker blue layers indicate higher flood depths. Swipe using the middle arrows to compare the two scenarios for Haiphong, Vietnam and Cape Coral, Florida.

About This Platform
The Coastal Risk Index is an open-source data platform designed to inform insurers, investors, policymakers, banks, and other decision-makers about climate risks and resilience strategies for coastal areas. The ultimate outcome we seek is to enable communities to be more resilient while protecting and restoring nature.

User
Benefits
The CRI is open to all. Users can view flood hazard maps for any coastal area and understand the avoided costs nature provides to both people and assets. Users can also examine areas of high social vulnerability and where investing in coastal Nature-based Solutions plays a role in protecting communities.
Financial institutions, insurers, governments, and development banks can leverage the data and insights on this platform for policy and product development.

Evolving The
Coastal Risk
Index
As part of the ongoing evolution of the CRI, we used the Dominican Republic as a case study to showcase where we would like to evolve the flood model and its data.
