Congratulations Dr. Margeson!

Keahna Margeson’s hybrid examining committee

Absolutely delighted to introduce Dr. Keahna Margeson, after a stellar defense of her Interdisciplinary PhD dissertation, Using Comparative Social Impact Assessment to Understand Resistance and Support for Causeway Removal and Tidal River Restoration . Defenses aren’t recorded, but if it had been, it would have been a great training tool. Thanks to Dr. Guadalupe Ortiz Noguera for serving as such an insightful external reviewer,  and to Wenda Greer, Helena Martel, and Peter Tyedmers for chairing, organizing and repping the IDPhD (and photography), respectively. Massive gratitude to Keahna, her committee and co-supervisor for a wonderful 4.5-year collaboration. Thanks to so many of the lab for coming along to support Keahna, and especially Elson for bringing the party. The occasion has made the whole week shine.

ResNet ECR paper out in Ecology and Society

One of the things that I think NSERC ResNet did well was try to invest in its early career researchers (ECR), with training, seed funding, and lots of opportunities to lead activities at AGMs and beyond. That was an important lesson from my first experience with large ‘team science’: that investing in ECR is always money well spent. One of the fruits of that ECR collaborative community has just come out in Ecology and Society, Co-envisioning an academia that fully embraces and supports early career researchers in interdisciplinary social-ecological research. Of the 13 authors, almost half (6) are from Landscape 1, the case study of the Bay of Fundy dykelands and tidal wetlands that I co-led. This includes, from my lab, MES students Emily Wells and Samantha Howard, as well as former PDF Lara Cornejo and current PDF Elson Galang (who started out in the synthesis team). L1 PhD students Brittney Roughan from SMU and Kiirsti Owen from UNB/Acadia are also co-authors. They used a range of scenario and other methods to develop their vision (visualized below) for the benefit of other teams of this kind. Congratulations to all!

New paper: Mi’kmaw lessons for realigning land relations

As an early Christmas gift, the paper from Emily Wells’ MES thesis, in collaboration with the Confederacy of Mainland Mi’kmaq (CMM), has just come out in Ecology and Society. The open access paper, Mi’kmaw lessons for realigning land relations in Bay of Fundy dykelands and tidal wetlands, is co-authored with Kara Pictou, who was our key collaborator at the CMM), and Melanie Zurba, Emily’s committee member here in SRES. It draws on Mi’kmaw Traditional Knowledge and interviews with key informants to explore the significance of tidal wetlands, dykes and dykelands to Mi’kmaq and how they approach coastal adaptation decisions as a result. I’ll quote from the paper to explain the outcomes, also shown in the paper’s Figure 2 reproduced below: “Overall, these considerations informed a general preference for wetland restoration. Indeed, a few participants considered restoration an opportunity for reconciliation. Mi’kmaw TK holder Ducie Howe explains:”

I know that probably [settlers] are not going to give [the land] back. But they can, as a way of reconciling, reconcile with the land. And do right by the land…that means our medicines that grow in that marsh, and our food, our relatives that need that land to be restored and viable for them to continue… That would be a form of reconciliation.

New paper: Image auto-coding tools for SIA

Yan Chen’s second PhD paper came out today in a special issue of Landscape Ecology on Artificial intelligence (AI) and landscape ecology: tools, perspectives, and complementarities. The paper, Image auto-coding tools for social impact assessment: leveraging social media data to understand human dimensions of hydroelectricity landscape changes in Canada delivers on what Yan said to me at the end of her Masters work back in 2016–after coding thousands of images manually–that maybe there is a way for computers to do more of the heavy lifting.

Locations of the chronosequence used in Yan Chen’s PhD thesis.

In this paper, we use the pre-trained AI Google Cloud Vision to understand the social impact of hydro dams based on social media of a chronosequence of sites (see right): from Mactaquac in NB (built in the 60s), to Oldman in AB (built in the 90s) and Site C in BC (which completed while her PhD was winding up). The paper has insights for the landscape and social implications of dam, and the use of social media for SIA. Congrats, Yan!

New paper: Q-method for rural large-scale solar

Last week a paper led by Emily Key (Snair), recent MES alumna, came out in Energy Research & Social Science, with her Dutch committee member Dirk Oudes (Wageningen) and I as co-authors. The paper,  Integrate and embrace or isolate and hide? Using Q-method to understand how to incorporate large-scale solar in rural Nova Scotia, Canada, is open access. This study doesn’t ask whether we should have large-scale solar (LSS), but how. Emily used Q-methodology, a statement-sorting methodology, with interviews, to identify discourses around LSS in rural Nova Scotia towns that have a range of experience with the technology. The two key discourses that emerged connect to some common debates in the literature around landscape management (see below). This allowed her to suggest important questions that should be discussed with communities being considered for LSS, questions that might be useful for lots of other sustainability transitions as well. Congratulations, Emily!
