Former L1 ResNet postdoc Lara Cornejo has led a tremendous new paper, out open access this week in Ocean and Coastal Management. The paper, Decision-making and ecosystem service dimensions of managed dyke realignment in the complex coastal landscapes of the Bay of Fundy, updates the simplified one-way flows we conceived for ecosystem service tradeoffs in our baseline 2021 Facets paper. Lara used system dynamics modelling to co-create with a range of experts–from universities, federal and provincial government departments, consulting firms, an ENGO and Indigenous organization (all co-authors)–models showing the decision-making processes leading to managed dyke realignment and the ecosystem service outcomes that result. The models drew on lots of published papers and student theses, and allowed trade-offs and synergies to be synthesized. But she didn’t stop there! She and McGill PhD candidate Elson Galang used the four scenarios that emerged from our environmental futures workshop in late 2022 as thought experiments for the models (see below). It is a great read. Bravo!

The PIs and partners discussing strategic planning in groups at Jouvence, during the ResNet AGM in Orford, QC, May 4-5, 2022.
It was wonderful to be physically present with about 60 of the national NSERC ResNet team at Jouvence in Orford, QC, for the first in person event since we were funded in mid-2019. It was a wonderful event, substantively and socially. Over 30 students and postdocs attended and drove discussions of science and ethics alike, and networked into working groups to strengthen linkages between the landscape, theme and synthesis teams into the second half of the project. There was lots of fun, including campfires and a pub viewing of my NHK debut . I got lots of new ideas for L1 (the Bay of Fundy dykelands and tidal wetlands case study) from talking to the students and postdocs about their work and returned to work reinvigorated, if exhausted. It was also really the first chance for the L1 team to gather together, and I enjoyed the extra time in this lovely setting to get to know one another.
Quebec’s return to indoor masking was a bit of a relief, and Danika van Proosdij and I took two days to drive each way for additional protection. It seems to have worked. That drive gave us the opportunity to show newly arrived L1 ResNet postdoc, Lara Cornejo, around the Bay of Fundy region. It was also my first time to the Converse dyke realignment site, though I didn’t find it as cold as Lara, and it was great to have Danika there as a tour guide. We also stopped by the St. Lawerence wetlands at La Pocatiere, and to see the wetland recovery where the tidal gate was removed on the Petitcodiac in Moncton.
Yesterday and today I’ve been enjoying participating in an OECD expert workshop on Resilience and the Ocean-Climate Nexus, an initiative of their new horizontal programme. This was cohosted by the Portuguese delegation to the OECD. I was invited to share experiences from Nova Scotia in a panel on OECD country experiences on ocean climate impacts and resilience, allowing me to update the Truro dyke realignment case study I led for the OECD volume Responding to Rising Seas a few years ago and talking about some more recent developments like the Coastal Protection Act. My co-panelists brought more national (Vasco Becker-Weinberg of Portugal on Marine Spatial Planning and the law), and international perspectives (Georg Borsting of Norway on the High Level Panel for a Sustainable Ocean Economy). Our discussion across these scales was productive and stimulating. I was glad for the opportunity to bring a coastal and social perspective to this event, with an RSVP list of over 260 people from 58 different countries, many of them practitioners or from government.
I had forgotten about my interview with local journalist Moira Donovan until an email from a colleague alerted me that the documentary she produced for CBC’s Atlantic Voice aired this morning. The short (26 minute) documentary is called Breaching Tradition, and does a nice job of telling the story of the challenges facing Bay of Fundy dykelands. Collaborators Danika van Proosdij (SMU) and Tony Bowron (CBWES) are featured as well, and several residents of areas like Nappan and Advocate Harbour whose communities and livelihoods are threatened. Donovan also put together a CBC news article by the same name: Breaching tradition: Salt marshes replacing Nova Scotia’s dikes. This is the setting and challenging management context for the case study I am co-leading in a new 5-year national NSERC project called ResNet.

Institutional entrepreneurship in Nova Scotia dyke realignment and salt marsh restoration, illustrated.
Congratulations to Tuihedur for his first paper from the postdoctoral fellowship that sees him working across Dalhousie and Saint Mary’s, out today open access in Sustainability. He used his knowledge of the institutional literature to ground our existing case study of the North Onslow dyke realignment and salt marsh restoration project–first written as the Canadian chapter in an OECD report Responding to Rising Seas–and analyzed it through the lens of institutional entrepreneurship. This involved synthesizing the characteristics of such entrepreneurs from the literature, mapping the existing jurisdictional responsibilities around coastal management in Nova Scotia, and demonstrating how those responsibilities were leveraged in the flood-prone Truro area. Even in the absence of coastal protection legislation, three government departments were able to collaborate to create a new ‘way of doing things’ that served their own objectives with coastal adaptation and flood mitigation as a happy by-product.
