States are turning to data and interactive maps to help residents confront and manage flood risks

2019 has been an unprecedented year for flooding, even before the start of hurricane season. Despite the number of devastating hurricanes in recent years, a new University of Notre Dame study published in Climatic Change found that most coastal residents do not plan to take preventative action to reduce damages.

In addition to speeding up the recovery process, taking action before disaster strikes can help homeowners reduce damages, save money and even lives. For riverine floods, every dollar spent before a disaster saves $7 in property loss, business interruption and death.

So how can individuals, businesses and the public sector be incentivized to make proactive investments to reduce vulnerability before a disaster strikes? The first step is clearly understanding risks—now and in the future—and having concrete recommendations for how to mitigate them.

In the past, FEMA’s National Flood Insurance Rate Maps have been the source for this information; however, these probability-based maps have not resonated with most people as they rely on the obscure “100-year floodplain” concept. Being told you live in an area that has a 1 percent chance of flooding any given year does not inspire action, nor does it reflect the reality of a changing climate.

In recent years, states have stepped up with more robust tools that give residents a clearer depiction of risks and resources for how to reduce them. Three states stand out. Read More »

Extreme wet weather in Louisiana and California highlights urgent need for newer, smarter strategies

Coauthored by Ann Hayden and Steve Cochran

It’s not often that communities in California and Louisiana face similar water challenges. California is better known for having too little water and Louisiana too much – both challenges exacerbated by climate change.

But record-setting wet winter weather led both states last week to release significant amounts of water from reservoirs and rivers to prevent flooding, underscoring the need for new approaches to build climate-resilient communities across the country. Read More »

Louisiana kids make a play for coastal comeback in Super Bowl ad

As millions of Americans prepare to watch the NFL’s season finale this weekend (despite most Saints fans boycotting it after an egregious “no call” in the Rams playoff game), a group of Louisiana children have been preparing an important message for state policymakers and election candidates – one that will air on local TV stations during Sunday’s big game.

The kids are using the ad to draw attention to a land loss crisis. Coastal Louisiana loses a football field of land to the Gulf of Mexico every 100 minutes because of the way the land and the Mississippi River have been managed, and now because of sea level rise.

Watch now, share with friends, and if you are from Louisiana, pledge your support for restoring the Louisiana coast at

Virginia is creating a coastal resilience plan. Here are 5 ways it can succeed.

Virginia is experiencing some of the highest rates of sea level rise in the nation and has suffered a 250 percent increase in federally declared disasters over the last 20 years. The commonwealth’s coastal and riparian communities are becoming more and more vulnerable to flooding and storm damage exacerbated by climate change.

The good news is that Virginia is taking proactive steps to make its people and communities more resilient.

Last month, Governor Ralph Northam signed an executive order designating an official chief resilience officer and directing the creation and implementation of Virginia’s first Coastal Resilience Master Plan to reduce the impacts of coastal flooding.

Here are five important points for Virginia policymakers to consider as they move forward with a coastal resilience plan. Read More »

How can we reduce losses from coastal storms? Monitor the health of our coasts.

With a rapidly changing climate and more frequent extreme events like floods and droughts, comprehensive environmental monitoring will be increasingly important for coastal planners, farmers and others invested in natural resource management.

Monitoring efforts can cover the whole spectrum of environmental and socioeconomic concerns to provide a holistic picture of ecosystem health over the short- and long-term. This can help to inform future decisions and planning based on the most recent conditions and trends.

However, it can be difficult to coordinate monitoring efforts across political boundaries and agencies, and monitoring is expensive to maintain over time.

Luckily, Louisiana is already a world leader in utilizing collaborative monitoring data to inform coastal restoration and planning efforts. Read More »

Coastal communities must plan for the future instead of planning from the past

Ecosystem restoration planning has traditionally been based on a desire to restore a system to some historic condition – even as conditions are constantly evolving because of climate change. Rather than planning for the future, we often look back at what the system once was and try to replicate it. But in a rapidly changing world, this model is not sustainable.

A paradigm shift, from restoration projects that solve past problems to those which address future conditions, is necessary if we’re to continue living in coastal areas.

Where I work in Louisiana, the Mississippi River Delta is facing an ongoing land loss crisis, due to a host of man-made and natural causes that is further exacerbated by the increasing effects of climate change.

To face this challenge, my Restore the Mississippi River Delta coalition colleagues and I, in collaboration with Tulane University, University of New Orleans and The Water Institute of the Gulf, began an effort to improve the future performance of coastal restoration projects. We started by identifying approaches and investment opportunities that support the long-term viability of the ecosystem – and the communities and industries that depend on it.

It’s our hope that this work will help Louisiana and other coastal areas around the country better plan for the future. Read More »

Climate change will force us to make tough decisions. Adaptive management can help.

In the face of climate change, it can be difficult to balance environmental, economic and community needs, but it’s a challenge we must overcome to adapt, survive and thrive.

To do this, professionals from multiple sectors across the globe are increasingly incorporating adaptive management techniques into resource planning for all kinds of essential ecosystems – from major watersheds like the Mississippi River Delta to high food production regions like the Corn Belt.

The lessons learned from past management decisions in these places will help shape resilience strategies for communities and industries around the world as they prepare for a new normal. Read More »

Environmental impact bonds can help make coastal communities safer, sooner. Here’s how.

Last year’s hurricane season was the most destructive disaster season in U.S. history, causing $265 billion in damage and forcing more than one million Americans from their homes.

As climate change causes weather to get more extreme, coastal communities across the country are struggling to find cost-effective solutions to enhance their resiliency to storms and develop new ways to finance that work.

This new technology allows you to visit coastal Louisiana from your couch

There is nothing like a boat ride through Louisiana’s Wax Lake Delta. This lush landscape, teeming with birds and wildlife, is an example of what Louisiana’s coast can look like if we use the Mississippi River to build land and increase the state’s resilience to storms and rising seas. It’s truly a beautiful place.

In stark contrast, a short plane ride over the region from New Orleans shows the true reality: Much of Louisiana’s coast is disappearing, as coastal wetlands cut off from the Mississippi River turn into open water. This Swiss cheese effect is startling when seen from the air. Read More »

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 »
