Alex and Keahna at BoFEP

It’s summer conference season, and two team members have just been to St. Andrews, NB, for the joint Bay of Fundy Ecosystem Partnership/ACCESS conference. Keahna had the opportunity to present early survey results from her Petitcodiac causeway survey, and talk about the larger study of which it is a part. Alex talked about the qualitative data analysis he led from our recent survey of apartment residents around the Minas Basin to understand their perceptions of coastal adaptation options like raising dykes, removing them to restore tidal wetlands and managed dyke realignment. He got a runner-up award for his poster. Conferences like BoFEP that are focused on a landscape/seascape, rather than field of study, are wonderful opportunities for engaging across disciplines.

Keahna presented preliminary results from the Petitcodiac case of her IDPhD research.

Ever busy, Alex presented two posters at the same time, one on his work with ResNet and one on his upcoming MI thesis work.

Congratulations, Emily Wells, MES!

Emily Wells speaks during her online MES defense, Mar 2, 2022, about being gifted an eagle feather by a Mi’kmaw Knowledge Holder during her research and what it meant to her.

Delighted to share news that Emily Wells defended her MES thesis yesterday, titled Mi’kmaw relational values: Lessons for environmental valuation from Indigenous literatures and L’nuwey along the Bay of Fundy Coast. Thanks to Heather Cray who acted as Chair, Melanie Zurba who was Emily’s committee member and welcomed her into the Co-Lab community, and also Kai Chan who served as her external examiner. It was too bad that threats of poor weather drove us to an online event, but it was still a wonderful conversation, exactly the kind of insightful and reflective event you hope for out of a defense. We have new ideas with which to approach the final thesis submission and the publication process.

New culturomics paper mapping CES using Instagram

Another nice lab output this week in Marine Policy led by Qiqi Zhao, a China Scholarship Council visiting PhD student in my lab last year, including a bunch of other lab-affiliated students as co-authors: Modelling cultural ecosystem services in agricultural dykelands and tidal wetlands to inform coastal infrastructure decisions: a social media data approach. It is a bit of a companion piece to the Chen et al (2020) piece in Ocean and Coastal Management, as it uses the same Instagram dataset collected for every dykeland area in Nova Scotia back in 2018, but in a very different way. Chen et al. took a very qualitative ‘small data’ approach to the dataset, analyzing the photographs (and accounts) only of posts that included the words dyke*/dike*/wetland/marsh in the captions. Zhao et al. used a ‘big data’ text mining approach, extracting and associating bi-grams (two-word strings) from geolocated post captions to particular cultural ecosystem services (CES), modelling those CES using SolVES and comparing (as with Chen et al.) dykeland and wetland services. Whereas Chen et al. only found direct mentions of freshwater marshes (specifically Miner’s Marsh), in Zhao et al. we leveraged the coordinates to locate those geolocated to tidal wetland sites.  This will help us better understand the tradeoffs associated with climate change-driven adaptations of the dykeland system in the Bay of Fundy, the focus of NSERC ResNet Landscape 1.

ResNet panel at BOFEP

Cover slide from our ResNet L1 BOFEP panel, May 19, 2022

Back in 2020 I submitted a proposal for a panel for the ResNet L1 team at the Bay of Fundy Ecosystem Partnership (BOFEP) meeting to be held in Truro. We finally had a chance to deliver that panel last week, after two years of delays due to COVID. BOFEP was held in partnership with ACCESS (Atlantic Canada Coastal and Estuarine Science Society) , which led to a very diverse set of presentations from isotope analysis to citizen science and beyond. Our panel was originally designed to present the Facets paper as it was in development; instead we showed how ResNet L1 was filling in the gaps in the conceptual model we presented in the Facets paper on services like cultural, storm protection, carbon, and pollination, and how that related to practice.Being in Truro also enabled a great meeting with ResNet partners, Confederacy of Mainland Mi’kmaq, visited lovely Victoria Park for a walk, and enjoyed a great public forum on flooding in Truro and the region.

That last item was the standout event for me. Truro Planning Director and a local African Nova Scotian resident demonstrated the political and justice dimensions of flood planning decisions in the region. Coincidentally or not, that theme was taken up yesterday on CBC Information Morning by Lynn Jones, who seems to be a part-time neighbour of that resident. The resident is now surrounded by homes that their owners could afford to raise on pads to the 1988 requirements currently in force for development on the flood plain, and he (downhill) feels he is receiving their runoff, worsening his situation. He can’t get insurance, but can’t really afford to raise or leave. He thinks the river should be dredged to store more water but the CBCL modelling suggests the sedimentation is so high it simply wouldn’t work. Meanwhile, Jones says her community, before they left or were squeezed out, used to ‘work with nature’ by keeping boats in the backyard so they could navigate the street, a pretty extreme form of what in adaptation terms would be called ‘accommodation’. She wants to see her community come back to these ‘ancestral lands’, but the risks today are higher than they were then. The past is a poor predictor of the future. This additional dimension to the challenges of Truro’s complex flood situation echoes those in other places like New Orleans where minorities are relegated to marginal lands, build strong communities and then are first displaced when conditions change: adaptation would mean not helping people to stay or return to such increasingly at-risk places, but such decisions have uneven impacts. Today, however, it sounds like flood plain development is still being permitted by Truro’s pro-development council and provincial UARB, in full awareness of expanding flood risk areas, locking in more risk and complexity for residents, the town and the wider public purse that will eventually have to wade in and make it right.

 

National Observer story on Chignecto Isthmus report

CBC’s Moira Donovan has written an article for the National Observer about the new report on the future protection of the Chignecto Isthmus. When it came out there was some consternation in the TransCoastal Adaptations team that nature-based solutions like dyke realignment and tidal wetland restoration weren’t built into the solution. There is at least 15 years of local research on the value of such approaches, and a great time series of dyke realignments to learn more from, but consulting engineers clearly aren’t leveraging it yet. The report options seem designed instead to prioritize agricultural land values and thus ‘hold the line’ with higher and stronger walls. Not even the NS Department of Agriculture that manages the dyke system on this side of the Bay has the ethos that all current dykelands can be maintained in the face of climate change.  NSERC ResNet is looking to understand the tradeoffs involved in these and other dykeland decisions, including complex dynamics such as carbon tradeoffs, salt water intrusion, and cultural implications across a range of constituencies.
