North Carolina must prepare for sea level rise now

North Carolina’s barrier islands (aka the Outer Banks) received the brunt of Hurricane Dorian’s impact to the U.S. mainland, but the damage could have been a lot worse had the storm not been weakened after ravaging the Bahamas as a Category 5 hurricane.

With the devastation of Hurricanes Florence, Michael and Matthew still in recent memory, North Carolinians did not need another reminder of the destructive power of hurricanes. However, Dorian highlighted the particular vulnerability of North Carolina’s barrier islands, and the need for us to develop solutions now for how this region confronts sea level rise and more frequent and intense storms.

Coastal resilience is getting high-tech, but there are still information gaps to fill

Coastal communities are struggling to accurately understand their flooding risks and identify appropriate solutions for mitigating the effects of rising seas and increased storm surges.

Fortunately, new technologies are emerging that facilitate more rapid acquisition of more accurate data and improve data visualization to support efforts to build coastal resilience.

[Tweet “New technologies are emerging that can help communities understand risk and build coastal resilience. https://www.edf.org/Ejp”]

Leaders in the private sector have already developed bold new technologies – from satellites and sensors to machine learning – to help understand risks and develop solutions. But this fourth wave ingenuity is not limited to the private sector. Several public sector entities offer innovative and readily usable resources to help build more resilient and safer coastal communities.

What the world can learn from Louisiana about living with climate change

Louisiana is emerging as a global leader in how to sustainably plan for the future in the face of increased storms, coastal erosion and rising seas. By combining nature-based solutions with traditional flood protection measures, Louisiana is a proving ground for living with climate change.

The lessons Louisiana can teach are not new, but they build upon those first taught by the Dutch. The Netherlands has taught the world innumerable lessons in flood protection – but historically, the Dutch have been primarily focused on building walls to keep water out, rather than finding more sustainable ways to protect coastal communities.

That is until recently, when the Dutch began embracing a more nature-based approach of “living with water,” similar to what is happening in Louisiana.

We can change the way we face coastal flooding challenges if we blend coastal restoration, protection and community resiliency measures. Louisiana’s multiple-lines-of-defense approach is a model for other coastal places, including the Netherlands, that are planning their futures in the face of climate change. Read More »
