EWN - Engineering With Nature

Nature-based solutions (NBS) are of growing interest in many parts of the world as scientists, engineers, policymakers, and others look for new ways to address climate change challenges. In S7, E2, host Sarah Thorne is joined by EWN cohosts Burton Suedel, and Amanda Tritinger. Their guest is Paul Cruz, Sr. Program Manager in International and Interagency Services in the USACE’s Pacific Ocean Division. They’re talking about advancing NBS by building relationships with colleagues in the Pacific region.

With a military background and experience in planning and security cooperation, Paul describes his work as: “I tell people I went from the 8-crayon box set to the 200-crayon box set with a pencil sharpener on the back, working with all these scientists, engineers, and research personnel on new and exciting topics and capabilities that we bring to the table as we engage our allies and partners all around Asia. And certainly EWN was one of those capabilities.”

While assisting the Philippine Navy with dredging efforts for their Navy Bases, Paul met with the Philippine Department of Public Works and Highways (DPWH). “We took advantage of the opportunity to support their dredging challenges because it was helping facilitate the military side, and we started to see a real growing relationship between the USACE and the DPWH—two agencies that have a lot of the same mission sets.” This led to additional engagements on typhoon recovery and flood control, and reclamation projects with the Philippine Department of Environment and Natural Resources.

In March 2023, Amanda participated in a technical exchange hosted by the Taiwan Water Resources Agency (TWRA). Over 100 participants from academia, local and federal agencies, and NGOs took part and expressed a great deal of interest in the knowledge that the USACE and TWRA had to share. As Amanda notes, “We enjoyed participating in the panel. I believe to this day we're applying what we learned and brought home to our respective countries.” Burton followed this up in October 2023, attending the Taiwan International Water Week hosted by TWRA. “It was a great opportunity to share some of our best practices and try to relate them in ways that the next generation of professionals—scientists, biologists, engineers, and other disciplines—can pick up on.”

In the Portland District in 2022 and in the Seattle District in 2023, USACE hosted technical exchanges with delegations from the Japanese Ministry of Land, Infrastructure, Transport, and Tourism (MLIT). Both countries face similar issues in their coastal environments. As Amanda describes it, “I saw a lot was multi-issue problems in Japan with compounding effects—flooding, plus wave action on storm events, and the most subsidence I'd ever seen, plus the risk of volcanic activity. While multibenefit may be seen as nicety for us, for Japan, it’s a necessity.”

These examples underscore the value of relationships in the Pacific Region. As Paul notes, “From a military perspective, we don’t do anything anymore alone. It’s always together.” For Burton, “To me, it’s mutual learning. I’m always pleasantly surprised how engaged and engaging the participants are and how much progress they have made to incorporate innovative EWN principles and practices into their projects.” Amanda adds: “Building deep relationships that are sustainable is so important. I think to progress the practice and support a sustainable future, we need to engineer with nature, but we need to engineer with humanity too.”

Welcome to a new season of the EWN Podcast! Our guest has a bold vision for natural, holistic land management. He's not just thinking about how water harvesting and land management can complement or even replace traditional water resources engineering, he's putting it into practice. In Season 7, Episode 1, host Sarah Thorne is joined by cohost Jeff King, National Lead of the Engineering With Nature Program, and Ricardo Aguirre, Director of Land Management and Water Security for WEST Consultants (WEST) in Arizona and Executive Director of the Drylands Alliance for Addressing Water Needs (DAAWN).

Ricardo is an engineer, rancher, consultant, and an accredited holistic management professional and educator. He has 25 years of experience working on hydrology, stormwater management, flood control, and groundwater recharge. Ricardo grew up on a cattle ranch and cotton farm in southern Arizona. The farm failed, and his family urged him to get away from agriculture, but his mother sensed that water was going to be the future in the Southwest and recommended he become a water attorney. Instead, he chose civil engineering with a focus on water resources. Following graduation from the University of Arizona, he worked at the US Army Corps of Engineers (USACE) in the Construction Engineering Research Laboratory (CERL) while completing a master’s degree at the University of Illinois.

After working in land development, Ricardo’s career brought him back to his family’s lands but with new perspectives on land management and water use. He started his own firm, Holistic Engineering and Land Management, then joined WEST to pursue his vision for regenerative land management. Regenerative land management, Ricardo explains, “is understanding nature’s patterns and working with nature to maintain landforms, specifically in this case, grasslands that do the yeoman’s work in the carbon and water cycles.” One of the core principles in this system is the need for megafauna, large livestock such as sheep and cattle. Ricardo says that, “in temperate environments, megafauna prevent forests from moving in on grasslands; and in arid environments, megafauna prevent grasslands from becoming a desert.”

To better understand these relationships, Ricardo and WEST have created a demonstration site on land purchased by WEST that used to be part of Ricardo’s family’s ranch. They are conducting a project to compare the impact of conventional grazing—a small number of animals in a very large area for long periods of time (months to years)—to high-density grazing—a larger number of animals in a very small area for very short periods of time (hours to days). As Ricardo explains, this high-density grazing concentrates and evenly distributes the beneficial animal wastes and the trampling of plants back into the soil to feed beneficial soil organisms. The animals then don’t come back to this land until the space is ready to be grazed again.

Also, in alignment with the principles of EWN, Ricardo is committed to advancing the practice of working with nature through training. He is an accredited professional with the Savory Institute and trains land managers in holistic management: holistic financial planning, holistic ecological monitoring, holistic land planning, and holistic planned grazing. In 2024, Ricardo will offer training courses through DAAWN, the nonprofit Savory Hub, one of a network of local learning centers affiliated with the Savory Institute that offer services to support local farming, ranching, or pastoralist communities, tailored to their specific needs.

It’s a new year and we’re kicking off a new season of the Engineering With Nature® Podcast! Season 7 launches on January 24. Host Sarah Thorne recently caught up with Jeff King, National Lead of the Engineering With Nature Program, to discuss highlights from Season 6 and give us a glimpse of what’s ahead.

The EWN Podcast launched in July 2020, and as Jeff notes, “One of the biggest highlights has certainly been the number of listeners that are coming to our space. For those out there, thank you so much for listening. He adds, “We really appreciate the interest and the support of our listeners from around the world. Everywhere I go—meetings, conferences, workshops—people are listening to our podcast, and they are truly engaged. They love what we’re doing. It’s incredibly exciting to get that kind of feedback.”

Sarah and Jeff review highlights from Season 6—the theme was Expanding the EWN Lattice. The wide array of topics covered included the historic wildfire season in Canada that dramatically affected air quality across Canada and in many US states; the application of nature-based solutions (NBS) in the Boston area to address sea-level rise, reduce flooding, and build coastal resilience; new guidelines for the application of thin-layer placement of dredged materials; the importance of dunes in the coastal environment; preservation of historic, culturally significant St. Croix Island by using NBS; and the science behind the importance of nature to health and well-being.

Season 6 featured a broad range of researchers, practitioners, and leaders—scientists, engineers, landscape architects, authors, and others—within the US Army Corps of Engineers (USACE) other US federal agencies, industry, nongovernmental organizations, First Nations, and others. All focused on innovative approaches to incorporating nature-based solutions into their work and encouraging others to do so. Sarah notes the synergy that continues to build among EWN practitioners, “All of these people are bringing their passion. I hope the work of all the people we’ve had on our podcast inspires the next generation to really dig in and learn these new techniques and advance the practices of EWN and NBS.”

The theme for Season 7 is Continuing the EWN Journey. As Jeff explains, “We want to continue on this journey—keep sharing more of the wonderful topics that come our way and the interesting people we are blessed to get to know on this journey. ‘Continuing the EWN Journey’ conveys that. Listeners can expect another impressive lineup of shows in Season 7, including episodes on innovative technologies; government policy related to nature-based solutions; discussions with international practitioners; conversations with leaders from not-for-profit organizations, agency partners, and Engineering With Nature USACE District Proving Grounds; along with coverage of important EWN events. As Sarah says, “So many people are really making a significant contribution to advancing NBS and EWN. We want to share their stories and their passion.”

Mark your calendar for the launch of Season 7 on January 24! In Episode 1, we’re speaking with Ricardo Aguirre, a rancher, practicing engineer, and educator who’s doing groundbreaking work applying EWN-type approaches to land management. He talks about how traditional practices have negatively impacted landscape and soils, particularly with respect to climate change. He is thinking about things differently in terms of holistic water harvesting and land management practices that can be more effective. We hope you’ll tune in.

Can nature make us happier, healthier and more creative? The simple answer is yes … and it’s been scientifically proven. In Season 6, Episode 10, hosts Sarah Thorne and Jeff King, Lead of the Engineering With Nature® Program, USACE, welcome Florence Williams, a renowned journalist, author, speaker, and podcaster who spent over three years traveling around the world talking with leading scientists about how to quantify the benefits of nature on people’s health and well-being. Florence joins us to talk about her book, The Nature Fix: Why Nature Makes Us Happier, Healthier, and More Creative, and what she has learned on her journey.

As a contributing editor for Outside Magazine, Florence is sometimes assigned stories; but when she was asked to write about the science behind why we feel good in nature, the assignment immediately spoke to her. What started out as a magazine story ended up as a book. In writing The Nature Fix, Florence was motivated by what she calls our “epidemic dislocation from the outdoors,” which involves the shift to moving to cities and simply spending less time outside. Florence notes the growing volume of scientific study in this area. “There’s a ton of mounting evidence. When you consider all these different scales and types of studies, it becomes really, really powerful.”

Florence likes to “witness the science”. The first stop on her journey was Japan, where a physiological anthropologist, Yoshifumi Miyazaki has been studying “forest bathing”. Florence explains “forest bathing is the idea of being in a nature space, almost like sunbathing.” She notes that after just 15 minutes of sitting in the woods or walking around trails there are significant positive physiological changes on metrics like blood pressure, respiration, heart rate, and hormone levels.

On another stop, Florence met with David Strayer, a cognitive neuroscientist. He believed that he got his best ideas after being on the river and became interested in the “three-day effect”—a term coined by a bookseller in Salt Lake City who noticed that some “magic” seems to happen after three days outside. Florence joined Dr. Strayer’s class, Cognition in the Wild at the University of Utah, when they went camping in the desert. “It was a helpful way for me to start to frame some of the theories about what’s going on in our brains and then of course to experience some of it too by spending three days outside.”

When asked about potential learnings for EWN, Florence notes the importance of designing spaces, especially in urban areas, where our senses can come alive in a comfortable way. “When we’re in modern life and in our cities, our senses are assaulted in ways that we just accept and don’t really think a lot about.” On a trip to Seoul, South Korea, she visited the Cheonggyecheon canal that had been redesigned to be a natural space. “They daylighted it and landscaped it and put trees around this canal. Acoustic engineers came up with water features and a walking path. When you descend into this lovely trail, you don’t hear the traffic noise. You hear the sound of water and birds.”

Florence believes that these kinds of urban natural spaces should play a significant role in infrastructure projects. Her call to action is this: “We can construct our lives in a way that helps facilitate our mental health; that should be a priority for all of us and for our children and for our neighborhoods. I really encourage people to get involved with their communities, encourage more trees, more playgrounds, more parks, more recess for kids.”

The USACE dredges more than 200 million cubic yards of sediments every year as part of their mission to ensure that ports and waterways remain open to traffic. In S5E6, we talked with Lt. Gen. Spellman, the 55th Chief of Engineers and the Commanding General of USACE, about his 70/30 goal to increase the beneficial use of these sediment from about 30% up to 70% by the year 2030. Supporting the USACE environmental protection and restoration missions, this ambitious goal calls for innovative uses of sediment. Our guests are advancing the practice of thin layer placement (TLP) through the development of new guidelines based on leading practice applications.

In Season 6, Episode 9, hosts Sarah Thorne and Jeff King, Lead of the EWN® Program at USACE, welcome Candice Piercy, Research Environmental Engineer at the Engineer Research and Development Center (ERDC), USACE; Ram Mohan, Senior Principal at Anchor QEA and Adjunct Professor at Texas A&M University; and Monica Chasten, Coastal Engineer and Project Manager in the Philadelphia District, USACE. Candice and Ram coauthored the recently published Guidelines for How to Approach Thin-Layer Placement Projects with their colleague, Tim Welp, a renowned dredging expert who passed away in 2021. Tim was the inspiration behind the guidelines, and this episode is dedicated to him. Monica is an innovator and leading light in the dredging community with responsibilities for keeping open the coastal navigation channels in NJ and Delaware. She was an early adopter of EWN and one of the first movers of beneficial use of dredge materials.

TLP is defined as the purposeful placement of thin layers of sediment (e.g., dredged material) in an environmentally acceptable manner to achieve a target elevation or thickness. As Candice explains, “TLP really reflects a different approach where we’re purposefully placing the material in relatively thin lifts to accomplish an ecological objective. We’re often doing this because the natural process of sediments collecting in our marshes is not sufficient for it to keep up with rising sea levels.”

Early in his career, Ram wondered whether dredged material could be used as a resource to improve coastal habitats. TLP essentially consists of spraying dredge material so that it rains down in a very gentle manner. Rom notes, “Whether you place it over a marsh or in a subaquatic habitat, this low stress placement method allows it to gently deposit over the existing bottom, making it very conducive to future recovery within two to three growing seasons.”

Monica gets passionate about sediment and doing the right things with it. “Prior to becoming a Project Manager for navigation projects, I was working on beach fill projects for the Corps where every grain of sediment is incredibly valuable. Then I moved into the navigation world in the back bays in NJ where we were basically throwing beautiful sediment away. Looking at all types of sediment and how we could use it innovatively became a mission for me.”

Jeff notes, “Sediment is supposed to move and be transported by natural processes in various areas of estuarine systems. When we take it out, we’re starving the wetlands. With TLP, these systems are going to be much better off.” Jeff adds that LTG Spellmon’s 70/30 goal and the new guidelines are game-changing: “I talk with practitioners all over the country, and I know people have been eagerly awaiting them. They are really going to move the needle.”

What happens when a world-renowned landscape architect from Thailand comes to the United States as Designer-in-Residence to work with an award-winning architect whose passion is what he defines as watershed architecture? It has been a year since Season 4, Episode 10 when we first asked that question of our guests, and now it’s time for an update.

Hosts Sarah Thorne and Jeff King, Lead of the Engineering With Nature® Program at the US Army Corps of Engineers (USACE), welcome back Kotchakorn Voraakhom (“Kotch”), an international member of the American Society of Landscape Architects and founder of Bangkok-based company LANDPROCESS, and Derek Hoeferlin, Chair of the Landscape Architecture program at Washington University in St. Louis. Derek and the Sam Fox School of Design & Visual Arts have been hosting Kotch on her year-long appointment as Designer-in-Residence, sponsored by the Pulitzer Arts Foundation.

Reflecting on her expectations for her year in St. Louis, Kotch said, “It is like a journey. When you travel into some new place or experience, you're expecting one thing; but when you actually go through it, you run into different things that you were not expecting.” Kotch spent her time learning from the St. Louis community and, as she says, listening to the ecology of the Mississippi River. Kotch taught Derek’s students at Washington University, held several workshops with community members, engaged with a range of people from USACE, and talked with people in small towns along the Mississippi who are dealing with perpetual flooding. Her residency has “been a pause to relearn what I have learned. As a practitioner, you want to conquer the world. You want to change the world. But in the end, you just have to let the world change you as well.” As she notes, “Nature has the final word.”

Derek relates a similar kind of experience in wanting to change the world, while also being influenced by it. His journey has been a 15-plus-year project to investigate what he calls “watershed architecture” and his interest in how watersheds can reflect a tipping point in time. Derek has been influenced by large-scale climate-related disasters and thinking about what it means to design buildings in that context. “As designers, we look at these larger-scale events and watersheds and what they mean for design decisions. Specifically, how can we engage water better within our design decisions. That's where we are right now with our conversation with the Engineering With Nature Program. We’re trying to think of a much more holistic way to bring communities into the next phase of this transformation.” These are some of the themes that Derek addresses in his recently published book, Way Beyond Bigness: The Need for a Watershed Architecture.

Jeff notes the inspiration that Derek and Kotch’s work together brings, “To be able to address these issues concerning climate change really is going to take us getting to know one another, to understand and appreciate our uniqueness as individuals, but also how do we harmonize as humans. Please keep pursuing and delivering good strategies and good solutions that will help us get past these existential threats. What you both are doing is incredibly inspiring for future landscape architects and others.”

If you've ever walked along a beach, you’ve likely noticed the dunes, the mounds of sand that have been formed by the wind. But have you ever thought about what those dunes do and how important they are? Perhaps not; our guests certainly have. In Season 6, Episode 7, host Sarah Thorne is joined by cohost Amanda Tritinger, Deputy Lead of the Engineering with Nature Program, and her US Army Corps of Engineers (USACE) colleagues Duncan Bryant, Research Hydraulic Engineer, and Nick Cohn, Research Oceanographer. All three are affiliated with the Coastal and Hydraulics Laboratory at the USACE Engineer Research and Development Center. They’re passionate about “dune stewardship,” protecting and restoring the dunes that create resilience for coastal communities. As Amanda describes it, “People tend to overlook dunes and the role they play in the defense of our coastlines during hurricane seasons.”

Duncan explains that dunes are formed by a combination of sand, wind that shapes the sand into mounds, and vegetation. They’re much more complicated than just the mounds of sand we see. Dunes are naturally very dynamic. They can form and grow. They can be eroded. They can shift. Nick adds: “A lot of these storms in the Outer Banks and elsewhere where we have big wind events during storms actually grow dunes pretty substantially, but what we hear in the news all the time is how storms erode dunes. That’s why they’re so complicated. Sometimes it’s just about the details; if there was one foot more of storm surge, that dune would get eroded out. So, we do lots of research both in the field and the laboratory and with models trying to understand what details matter about our prediction of dunes.”

Dunes are a critical nature-based solution. As Nick explains, “Dunes serve as a topographic high that prevents high water from flooding people’s property and critical infrastructure. And they’re a really cost-effective, natural form of infrastructure to prevent flooding. As we get through the end of hurricane season, I think we always try to make the case that dunes are a valuable form of coastal protection that can be put almost anywhere throughout the world, without hard structural solutions.”

Amanda underscores the potential value of dunes for coastal resilience: “I think expanding the use of dunes is an exciting prospect. Everybody in the coastal community has some major storm event, some hurricane, that sticks in their mind. For me, it was Hurricanes Matthew and Irma. For both, I was in northeast Florida, and we did forensic studies before and after each of those storms. You could walk up and down the coastline and just see the difference. The communities that had older, more natural dune systems got out almost unscathed, whereas the communities that had newer dunes or no dunes saw a lot more damage after the storms.”

Amanda’s call to action speaks to her passion as a dune steward: “Understand the dunes. Take the time to learn the dune story. If you go to the beach and you appreciate the water, that magical place where the water meets the land, where we get to touch the rest of the world, know the story of the dune. It provides that ecological benefit. It takes care of the communities behind it. It’s dynamic. It’s exciting. It’s doing its job if it’s disappearing and it’s doing its job when it builds itself up. Just appreciate the dunes when you’re out there. I just think if more people knew the dunes story and told each other about it and knew just how magical that thing they walk over on the way to the beach was, that that would just be a win in itself.” For more information and resource links, please visit the EWN Podcast page on the EWN website at https://www.engineeringwithnature.org/

This episode starts with a story. In 1604, 79 members of an expedition from France, including Samuel de Champlain, came to Saint Croix Island off the shores of Maine and New Brunswick to set up a colony in the new land. They called it l’Acadie—Acadia. Over the severe winter of 1604 to 1605, 35 of the settlers died, likely of scurvy. In the spring, members of the Passamaquoddy Tribe befriended the French survivors and brought them food; and, ultimately, their health improved. In the summer of 1605, the survivors moved the Acadia settlement to Port Royal, Nova Scotia, and the rest is history. The Acadians went on to play an integral part in the histories of Canada, the United States, and France. Today, that 6.5-acre uninhabited island and its very significant history is threatened by high tides, shoreline erosion, powerful winter storms, and more—all exacerbated by climate change.

In Season 6, Episode 6, host Sarah Thorne is joined by cohost Jeff King, National Lead of the Engineering With Nature Program, US Army Corps of Engineers, and the USACE Project Lead for collaboration on the Saint Croix Island activities; Donald Soctomah, Tribal Historic Preservation Officer for the Passamaquoddy Nation; Becky Cole-Will, Chief of Resource Management for Acadia and Saint Croix Island National Parks, US National Park Service; and Amy Hunt, Senior Project Manager at EA Engineering, Science, and Technology, Inc. in New Hampshire. They are working together to figure out how to use nature-based solutions to protect and preserve Saint Croix Island and its unique historical significance.

Each of the guests speaks to the unique nature of Saint Croix Island and their personal affinity to it. Donald notes that “Saint Croix has always been a special place, not just for the one winter that the Acadians spent on it but also for the last 15,000 years of Passamaquoddy history.” The guests also note the Island’s importance as a symbol of the impacts of climate change. As Donald notes, “When I look at the Island I see a symbol of the change that’s going on related to climate. Because right before your eyes, you can see the rising ocean, the erosion, the shrinking of the Island. Every time I look at that Island, I think about climate change and the importance of trying to make other people aware of it.”

In June of 2023, the National Park Service hosted a workshop that brought together about 25 participants—biologists, geologists, engineers, planners, policymakers, and Tribal officers—to discuss the challenge and the opportunity and learn more about the history of the Island. The purpose, as Amy describes it, “was to ask the right questions and cast a really wide net then whittle it down to a few specific priorities.” Becky adds, “The first day we spent thinking about what could be done. Then people had an opportunity to get out there and see the Island and say, ‘I get it now.’ There was a lot of reality checking and ground truthing that was fascinating to hear.”

Jeff appreciated the guests sharing their insights and perspective. He noted that the work is ongoing: “We’re just getting started. Brian Davis at the University of Virginia has been working collaboratively with the project partners to come up with designs and renderings that we want to discuss with Donald and the Passamaquoddy Tribe to ensure that we’re integrating traditional ecological knowledge along the way. I’m excited about where we’re headed and the opportunities this project will offer.”

As fall gets into full swing, we’re kicking off the second half of Season 6 of the EWN Podcast by talking with members of the EWN leadership team about what they’ve been working on and what’s ahead. In Episode 5, host Sarah Thorne is joined by cohost Jeff King, National Lead of the EWN; cohost Amanda Tritinger, Deputy Program Manager, EWN; and Courtney Chambers, Communications Lead, EWN.

The summer of 2023 was an unprecedented summer in many ways. As Sarah notes, “Mother Nature certainly demonstrated that climate change is upon us.” Jeff agrees, revisiting the topic Canada’s worst wildfire season ever, covered in Season 6, Episode 4, as well as the wildfires that devastated Lahaina, Hawaii. He also talks about the extreme rainfall and flooding in the southwest caused by Tropical Storm Hillary and the extraordinary flooding and devastation caused by Hurricane Idalia to the big bend area of Florida. As Jeff notes, “People in all parts of the US, Canada, and around the world are experiencing the effects of climate change firsthand.” This global wakeup call is challenging and motivating for the EWN Program. Jeff notes that there are 49 active research projects being led by personnel at the USACE Engineer Research and Development Center to address the climate change imperative by integrating nature-based solutions.

As Communications Lead, Courtney Chambers is responsible for sharing the incredible work that is going on with EWN. In her discussion with Sarah, Courtney describes some of what she has been doing to support the development and promotion of publications critical to broadening the reach of EWN, including the next volume of the EWN Atlas series, which captures the essence of EWN and nature-based solutions through images. As Courtney notes, “If you’ve seen Atlas I or II, you know that these books really showcase the potential for EWN and the diversity they can include.” Sarah adds, “You’re helping to share the stories of all of the brilliant scientists, engineers, landscape architects, and other collaborators—and the EWN projects that they’re working on—to inspire others. It’s important work.”

Sarah also speaks with Amanda Tritinger. Amanda shares highlights from her recent trip to Taiwan, coordinated with the USACE Pacific Ocean Division (POD). She was invited to talk about opportunities to engineer with nature as part of the information and technology exchange with the Taiwan Water Resource Agency. “The TWRA has a lot of really cool projects. It was exciting to share what EWN has going on but also to learn a lot of what Taiwan has been doing.” Amanda notes that through the POD they have been involved with a lot of opportunities in Southeast Asia with colleagues in Japan and Vietnam. “It’s really exciting that the world is a big place and what seems like a problem can be its own solution through the use of natural infrastructure and better understanding the environment around us.”

In closing, Jeff notes, “The climate change that we’ve all been experiencing is really challenging and motivating our EWN colleagues and collaborators to be innovative—to conduct research and field work on a range of projects that can help mitigate the impacts of climate change and help communities adapt and become more resilient. I really look forward to sharing some of the truly groundbreaking work underway on future episodes of the EWN Podcast. I don’t think we’re going to run out of interesting things to share with our listeners!!”

In late June, while preparing for this episode, there were over 500 wildfires burning across Canada. Smoke from the wildfires was affecting millions of Canadians and Americans across a wide swath of North America with air quality indexes reaching extreme levels. As of the posting of this episode (July 25, 2023), the number of wildfires burning across Canada had grown to over 1000 with 660 classified as “out of control”. Our timing to have a conversation about wildfires with a prominent Canadian scientist could not have been more relevant.

In Season 6, Episode 4, host Sarah Thorne is joined by cohost Jeff King, National Lead of the Engineering With Nature Program, US Army Corps of Engineers, and Anabela Bonada, Manager and Research Associate at the Intact Centre for Climate Adaptation at the University of Waterloo in Ontario, Canada. Among other things, Anabela is an expert in forest fires and has been actively involved developing a user-friendly guide for residents to simplify the recommendations in Canada’s National Wildfire Guide.

Canada’s wildfire season started early this year. Anabela puts the current situation into context: “The Canadian Interagency Forest Fire Center reports that [as of July 5] over 85,000 square kilometers, or almost 33,000 square miles have been burned so far. This is equivalent to a little bit more than New Brunswick and Prince Edward Island, in Canada, combined or a little bit bigger than South Carolina in the US. This is already the worst wildfire season on record for Canada.”

She notes that with climate change, drier and warmer seasons are expected going forward in Canada and the US, particularly in an El Niño year. “For North America, it means that we’re going to see drier, warmer climate in the West and Northwest, areas that are usually wildfire prone, and parts of Canada. The expectation is more wildfires—in size and intensity.”

There’s a lot of work underway in Canada to raise awareness about wildfires and to make communities more resilient. The Intact Centre, in collaboration with FireSmart Canada, has developed easy to follow guidance for homeowners and for communities to get ahead of wildfire risks. As Anabela notes, “There are things that you can do around your home, from simple, moving any combustible material 10 meters (about 33 feet) away from your home, to more complex, like considering a Class A roof that is resistant to wildfire.”

Anabela goes on to note that a more nature-based solution is to focus on changing the natural drivers that lead to extreme wildfires rather than fighting the fires after they have started. “So, our focus needs to shift from suppression to prevention as we consider nature-based solutions to wildfire.” Anabela’s call to action with regards to wildfires is, “We need to take action, now—all the way from policymakers right down to every individual.”

Jeff agrees and adds: “I am thinking about collaboration and the fact that wildfires really don’t respect borders. What can we be doing now and in the future? I want to think about what kind of collaborative research is needed and how we pursue that—including how natural infrastructure and nature-based solutions can be used in advance of a wildfire event but also following wildfire events.” For more information and resource links, please visit the EWN Podcast page on the EWN website at https://www.engineeringwithnature.org/
