Coastal reports and coverage

Two things are out from the lab this week on topics coastal.

Keahna Margeson, IDPhD student and 2023 OpenThink cohort member, had a commentary published in the Conversation called Let coastlines be coastlines: how nature-based approaches can protect Canada’s coasts. It is a great read!

The release of the report on last year’s scenario planning workshop for the Bay of Fundy coast was covered in DalNews. The report, Envisioning Environmental Futures for the Tidal Wetlands and Dykelands of the Bay of Fundy, is led by Elson Galang, the PhD student at McGill who led the workshop, but with lots of lab folks in the mix, including Keahna, Lara Cornejo, and Polly Nguyen.

Two reports have also been uploaded to Borealis based on ResNet work by team members. These works set strong groundwork for others to build on.

New paper: social media methods for SIA

Synthesis figure in the new Current Sociology paper showing sample workflows within a range of possibilities.

This week a new open access paper came out in a special issue (monograph) of Current Sociology about Social Impact Assessment. The special issue was led by Guadalupe Ortiz and Antonio Aledo, and their introductory essay is worth a read, as is Frank Vanclay’s epilogue, reflecting on 50 years of SIA and asking “is it still fit for purpose?”. Our offering, Social media and social impact assessment: Evolving methods in a shifting context, reflects on a decade of research using mostly Instagram to understand the social impacts of developments such as hydroelectricity, wind energy and coastal dyke realignment. The above demonstrates the current state of the art in terms of workflows, and shows how several of our studies have navigated those options. The paper also talks about the challenges, practical and ethical, of using social media datasets, and calls for government support in securing ongoing access for the purposes of public good research, a topic also recently argued by Ethan Zuckerman in Prospect Magazine. Most of the work synthesized in this paper has been published elsewhere, except the brilliant work that Mehrnoosh Mohammadi did on developing a collage approach to communicating common features in social media images to protect both copyright and privacy concerns (see below). This is a method we advocated back in 2017 and it is wonderful to see it in action.

New survey in the field

Postcard coming through CanadaPost Admail soon to Kings, Hants, Cumberland and Colchester counties.

Very soon, people who live in multi-unit dwellings around Hants, Kings, Colchester and Cumberland county in Nova Scotia will start receiving postcards like the above from my lab. Samantha Howard is running a focused study to strengthen our understanding of how people in the region think about (and maybe use) dykelands and tidal wetlands. If you get one of these in your mailbox, and you have 8-10 minutes to spare, we would be so grateful to hear from you.

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.

New paper on salience mapping of energy infrastructure

Figure 1 in Mohammadi et al (2023), showing the novel sequence of work in PhotoShop, Matlab and GIS to understand how energy infrastructure affects a view.

Really nice to see a paper come out this week in Impact Assessment and Project Appraisal from Mehrnoosh Mohammadi’s MES thesis on renewable energy infrastructure in amenity (specifically vineyard) landscapes. This is the kind of thing that happens when a landscape architect joins your lab. This work involved a creative sequence of PhotoShop (to remove energy infrastructure seen in Instagram images taken at vineyards), Matlab (to calculate visual saliency), and ArcGIS analysis to understand the change in salience wrought by the removal. Cool stuff! This started out as a research note at submission, but got upgraded by the editor: A saliency mapping approach to understanding the visual impact of wind and solar infrastructure in amenity landscapes. Thanks to PhD student Yan Chen and former postdoc H. M. Tuihedur Rahman for helping out on this work.
