    Coastal Resilience on Capitol Hill: Protecting the United States’ Infrastructure, Economy, and Security

    July 24, 2018 By Rebecca Lorenzen

    Every dollar invested in preparing for natural disasters could save seven dollars, said Alice Hill, Research Fellow at the Hoover Institution, at a recent briefing on Capitol Hill. Catastrophic events like Superstorm Sandy present significant financial risks to U.S. businesses, the federal treasury, and the global economy. These complex emergencies have taught us that “everything is connected: our transportation system failed, our health sector failed,” said Hill, in the wake of these storms.

    Hill and Wilson Center Global Fellow Roger-Mark De Souza, who is president & CEO of Sister Cities International, presented a new report, Building Coastal Resilience for Greater US Security, which was co-edited by the Hoover Institution, Wilson Center, and the Stanford Woods Institute for the Environment.

    Around 39 percent of the U.S. population lives in coastal counties. In 2018, we have already witnessed some of the highest temperatures ever recorded, and sea-level rise is accelerating, said Hill. These changes threaten infrastructure, economic growth, and national security, with 128 U.S. military facilities at risk from just three feet of sea-level rise, according to the Union of Concerned Scientists.

    The report also recognizes the critical issues around displacement tied to climate change and sea-level rise. While conflict also plays a significant role in displacement, said De Souza, environmental stressors can “serve as a threat multiplier that leads to greater instability.”

    Recommendations for a More Resilient Coast

    More data and information on these threats could help coastal communities adapt to the coming changes. The report’s recommendations include updating floodplain maps, making downscaled data available online, developing decision-support tools at a local level, and encouraging citizen scientists to gather local data. Private sector stakeholders should be engaged, said De Souza, since they operate key infrastructure and thus have access to valuable data and information.

     “There are a number of opportunities to develop a resilience dividend,” said De Souza, “so that when events happen…we’re able to bounce back better,” such as early warning systems and innovative financial mechanisms. Resilience bonds, for example, help anticipate risk and protect against future disasters.

    Resilience tools like these can not only save lives, said De Souza, they can provide economic, environmental, and social benefits. Coastal infrastructure to protect against storm surge, for example, should combine manmade and natural barriers, such as marshes, oyster beds, and coral reefs, which also have economic benefits by supporting seafood industry and tourism.

    Addressing the impacts of climate change on coastal communities must overcome the “tragedy of the horizon:” the difficulty of planning effectively when we are faced with a “slow-moving change that has devastating impacts,” said Hill; if we don’t, “we’re investing in a losing asset with no long-term plan.”

    • What happens when you can’t build back? Many communities may not be able to avoid or adapt to climate changes, and thus suffer what the climate community calls “loss and damage.”
