Meddylfryd yr anterth

A quick thanks to the PloCC (Places of Climate Change) network at the University of Bangor, Wales, for the invitation to present to their monthly seminar series on Nov 9th. I spoke about climax thinking (the title of this post is its Welsh translation, literally, “the mentality of the peak” according to Google Scholar) using examples from wind energy, coastal adaptation and flood-risk mapping (highlighting work by past and current graduate students Kristina Keilty, Ellen Chappell, Krysta Sutton and Samantha Howard). Thanks to the effort PloCC took to translate my abstract, I’ll share it here for any Welsh speakers who discover this page.

Trosiad yw meddylfryd yr anterth am wrthwynebiad i newid y dirwedd er lles y cyhoedd. Deilliodd o ymchwil seiliedig ar le yn Nghanada Atlantig. Yn yr un modd â damcaniaeth olyniaeth mewn ecoleg, rydym yn aml yn credu bod tirweddau mewn cyflwr delfrydol neu ecwilibriwm (h.y. yr anterth), ac y dylid dychwelyd ato ar ôl pob aflonyddwch megis trychinebau naturiol. Mae angen inni symud at ffordd ddi-ecwilibriwm o feddwl am dirwedd o ystyried yr heriau a wynebwn o ran cynaliadwyedd a’r goblygiadau posibl i’r dirwedd. Dyma gyflwyniad sy’n rhannu gwaith achos ynglŷn â gosod ynni’r gwynt, enciliad yr arfordir a mapio perygl llifogydd i symud o lefel y canlyniad (gwrthiant) i lefel y broses (achosion) y syniad newydd hwn, a’r goblygiadau i ymchwil ac ymarfer.

Topically, a great example of climax thinking came into my morning news media today, in the local rejection of government-funded wind turbines to help Stewart Island, NZ, get off of diesel generators. As the term otherwise hurtles to a close, and I look ahead to the Restoring America’s Estuaries conference in New Orleans the first full week of December, I’m keeping my eye to related media. I look particularly forward to the NYT reporting about this call for experiences of disaster rebuilding. A final note, do yourself a favour and read Rutger Breman’s book Humankind; I listened to the audiobook through the Halifax’s library’s Libby app on a long bus trip and it made me feel much better.

Scenario workshop for ResNet

Last week was very exciting, as NSERC ResNet Synthesis team members Elson Galang and Elena Bennett came to Halifax to lead us in a scenario workshop for the L1 landscape case study of the Bay of Fundy dykelands and tidal wetlands. Eighteen interested parties joined us at the SMU CLARi site for a fun two days of reflection and visioning, and we finished up with four fascinating narratives of potential futures for the region. The creativity and expertise of our stakeholders resulted in some futures I’d never considered, but that were remarkably well fleshed out.  I had never been involved in deploying such a method, and after the two days I am a big believer in its transformative potential (at least with Elson at the helm!). Thanks to everyone who contributed beyond those already mentioned, including postdoc Lara, TCA project manager Kristie, and grad students from Dal (Paria, Polly and Keahna) and SMU (Millie, Evan).  I am looking forward to co-developing the workshop report and getting our work out in the world.

As an aside, I also had a first appearance in the Christian Science Monitor while the workshop was on. Another nice piece by Moira Donovan about the situation on the east coast post-Fiona, particularly in relation to managed retreat. These are interesting times in Port aux Basques, as 100 residents affected by Fiona have received demolition notices for buildings they own: I’m waiting to hear what support they’ll get to safely and meaningfully retreat.

Bye to Qiqi

Every once in a while a student will email you out of the blue and ask if they can come work with you. Sometimes you really strike it lucky, too. I was delighted to host Nanjing University PhD candidate Qiqi Zhao in my lab for the last year, working on landscape culturomics in the Bay of Fundy. She extended work by Yan Chen, Tuihedur Rahman and a former French visiting student Camille Caesemaecker, using the same Instagram dataset to understand dykeland and wetland cultural ecosystem services. Her approach leveraged SolVES modelling, which she was already deploying in her own PhD on forest park CES in China. We coauthored three papers together, drawing in other members of my lab and the wider ResNet team (including some text mining techniques), and have plans for one more (at least!). Thank you for your hard work, Qiqi!

Atlantic Flood Mapping Conference

Samantha Howard presents her Honours and early Masters results at the Atlantic Flood Mapping Conference in Halifax, Oct 5, 2022

The last week was a busy one. I enjoyed doing a guest talk for the University of Massachussets at Amherst’s ECo Seminar series last Friday. I updated my 2020 keynote for IASNR, including insights from Samantha Howard’s Honours and Masters surveys on flood risk mapping. Thanks to Jesse Caputo and Brett Butler for the invitation to spend more time reflecting on what I’ve been learning about climax thinking over the past few years of empirical exploration.

This week I squeezed the Atlantic Flood Mapping Conference into my week. On Wednesday, Samantha presented her work to a remarkable assemblage of government, NGO, consulting, academic and other experts in the technology and human dimensions of flood risk and hazard mapping. We could hardly have asked for a more appropriate audience. On the Thursday, after my class, I took part in the workshop component of the event. As part of one of those sessions, I presented some of the social science principles that underlie public resistance to flood risk or hazard mapping, to set the stage for breakout groups on best practices in communication. I included in my presentation media analysis work done by former MREM M.J. Valiquette (funded by CBCL) to inform their flood mapping guidelines for Nova Scotia municipalities.  Unfortunately, my session at this event conflicted with the book launch for Power of Landscape in the Netherlands, which I was sorry to miss.

The end of the day on Thursday, I was delighted to have an (uninterrupted) talk with Jeff Douglas, on CBC Mainstreet NS, about managed retreat. They quoted from my last blog post to get things started, but the conversation was fun and wide-ranging. You can have a listen here.

Fiona

A view from my morning commute on Tuesday, along Quinpool Road; a silver hatchback still sits crushed under that tree.

As September comes to a close, the whole Atlantic region is still reeling from the impact of Hurricane/Tropical storm Fiona, which hit last Friday night and Saturday morning. Many remain without power and/or out of their homes and–most horrifyingly–some have lost their homes and/or their lives in the storm. Many beautiful coastal towns and holiday communities lie shattered, and sad, scary stories abound: I even knew the person missing and presumed lost on the NS coast. My home and family were thankfully spared, and we’ve started feeling a bit guilty about this as the recovery ahead looks so long for so many.

There will need to be a time, however, after the first stage of emergency response and before the recovery process begins in earnest, to ask questions about how and where that should happen. I think some people feel like a big storm like this is so rare and unlikely that once it is past, they are safe for a good while. That is not how it works, unfortunately, and certainly not anymore. With climate change these outsize events will become more common, so this storm is a very stern warning to those who live in vulnerable coastal areas. People may think the changes associated with the climate will come slowly and they’ll have time to react and to decide, but storms like this show they likely won’t. Change will be noisy and unpredictable, not gradual. What we have seen is an extreme form of unmanaged retreat. It’s the worst case scenario, but we’ll have more of if we don’t listen to the lessons Fiona offers and be proactive.

There is a policy window now to consider managed retreat in a coordinated way that supports local communities to reimagine what it might look like to thrive coastally. I did a little media for the Toronto Star and Toronto’s News 1010 morning show in the last 24 hours about this. There will be a lot of insurance and emergency response money flowing, sooner or later. I hope that the political pressure to use such funds to rebuild in situ, regardless the risk, can be shifted to a broader conversation about the resilience that comes from leaving more space for the ocean to do its thing. It’s thing is dynamic, and against that dynamism hard infrastructure will always have it’s limits. Getting out of the way won’t. Yes, this might mean sacrifice, for instance new regulations and constraints on land long-held and cherished (such as the setbacks proposed in Nova Scotia’s Coastal Protection Act), or a lower tax base for municipalities. The conversations won’t be easy and the implications will be uneven, falling at times on people who will need more public support than others to accomplish it. But we should tackle it as a shared challenge, a duty not only to current generations but also future ones.

Last week I was doing revisions for a paper and a reviewer pushed back against the estimation of the length of the Nova Scotia coastline that I had included in my paper. I looked around and found others had used mine but also two other dramatically different numbers. In the end I decided not to include a length, because, well, how do you measure a coastline anyhow? But it is always constantly changing, as the recent PEI pre/post imagery shows quite well.  An unavoidable lesson from Fiona is that coastal stability is an illusion. We need to learn to live with that fact.
