After the flood: 49 reasons your community may be more vulnerable

By Heather Bean. This article from Waterloo News is published in recognition of Earth Day 2021.

When a flood hits a Canadian community and rising waters wash out roads, governments at all levels respond with heroic evacuations of vulnerable residents and emergency food and shelter.  

But what are the hidden costs to communities when flood waters recede, and why are some left devastated while others rebound? 

“We know how much it costs to rebuild a washed-out road. What we don’t consider is the cost of people getting knocked out of the workforce, suffering mental health problems as a result of the shock, and the ripple effect throughout the community. And we know from research that those costs tend to be much higher,” says Jason Thistlethwaite, a professor in the School of Environment, Enterprise and Development and an expert on flood risk. 

“The bigger numbers hidden in there are the long-term costs, the social costs, which don’t get captured in the initial disaster appraisal,” he says. 

Tool pinpoints flood and socioeconomic risk 

Thistlethwaite wants to help governments make better, long-term plans with better data. He co-leads the Climate Risk Research Group (CRRG) which is developing a tool that pinpoints the areas in Canada where flooding risk overlaps with socioeconomic vulnerability. 

To build it, they’ve established the country’s only data-sharing partnership with global flood risk management company JBA Risk Management. That gives CRRG access to Canada’s first comprehensive flood risk model. But a map of flood risk can’t give the full picture. To identify where flooding would be most devastating over the longer term, Thistlethwaite says they have developed what they believe to be the most comprehensive socioeconomic vulnerability index in Canada.” 

49 ways communities are more vulnerable 

It was no small feat. Working with grants from the Social Sciences and Humanities Research Council (SSHRCC) and the Marine Environmental Observation Prediction and Response Network (MEOPAR), Thistlethwaite and Ph.D. student Liton Chakraborty spent three years developing and creating visualizations of the index. The team looked at existing best practices for building socioeconomic vulnerability indexes and studied examples from around the world to determine which indicators to include. “We wanted ours to be better,” he explains. The resulting index includes 49 indicators of vulnerability, such as low income, multiple family members, and access to community and emergency services.” 

Getting the data from Statistics Canada was a long process. “You have to go through a rigorous process to use that kind of sensitive information.” Then came the testing stage: “Our PhD wanted to make sure we validated our assumptions through econometric and statistical analysis to make sure the results we were coming up with weren’t random.” Finally, the team overlaid their data with JBA’s map of flood risk to reveal Canada’s areas of greatest vulnerability to floods. 

The next steps involve getting their information into the right hands. Their research already has strong support from Public Safety Canada and Natural Resources Canada: “We’re making sure that whatever we know, they know as well,” Thistlethwaite says.  

Tool will help cities decide where to safely build

Andrea Minano, a PhD Candidate and manager of the Climate Risk Resource Group, is working to develop tools that visualize the teams research, including the use of geographic information systems to help local governments make decisions about where to safely develop land, where to mitigate effects, and when it’s time to start thinking about managed retreat: relocating a community that can’t be protected from cycles of repeated flooding. Thistlethwaite wants to connect with the Canada Mortgage and Housing Commission, as well as municipalities across the country. 

Most of all, though, he wants everyday citizens to have access to their flood risk information. “We want to empower Canadians to go down to city council and question the logic of putting a development in a high-risk area, when we have data that in the event of a disaster, the community will be socializing that risk, with no liability for either the municipality or the developer.” 

“These are not Acts of God; these are acts of poor governance, and their effects are predictable. The fact that they continue to happen reveals that governments are ignoring science, and it’s time we held them to account for these failings.”  

GreenHouse students set their sights on sustainable solutions

Given the growing impact of climate change, building environmentally sustainable products and services has become more important than ever before. So, it comes as no surprise that GreenHouse (GH) students continue to build ventures with a sustainability focus. Whether it’s a product or service to help you consume more sustainably, or an idea to support existing businesses transition into a more sustainable business model.

We took the time to catch up with two of the winners from the most recent Social Impact Showcase who focused their ventures on sustainability for social impact.

Sup Zero

Fourth-year Environment, Resources and Sustainability (ERS) student Ashoke Mohanraj was experiencing the pains of clunky supplement packaging every time he bought a new product to support his health and fitness goals. From protein powders to nutritional supplements he purchased, he noticed the packaging was unappealing, took up a lot of space and every time he bought new supplements, it was generating unnecessary plastic waste.  

With this problem in mind, he came to GH’s Social Innovators in Training program looking for support with resources and direction for his idea, Sup Zero. The venture aims to provide consultancy to small or medium-sized supplement companies looking to create more responsible and sustainable packing solutions for their customers. Noticing consumer trends, Mohanraj liked the idea of replacing the clunky and wasteful plastic supplement containers with a more elegant solution such as a glass jar and utilizing biodegradable packaging for supplement refills.  

He felt uniquely positioned to solve this problem using consultancy since he could leverage the technical expertise gained from his ERS degree and experience in the health and fitness space as a powerlifter. 

“I never would have considered myself to be an entrepreneur,” says Mohanraj. “But I have really enjoyed becoming part of the GreenHouse community, it has been a great resource for helping me build out my idea and make good connections.” 

Sup Zero has recently been awarded $2,000 in funding from the Social Impact Fund to support the design of the sustainable packaging and to pilot the system with local partners this summer.

ChangeRoom

Started by two first-year Engineering students, Ayush Bhargava and Raymond Wu in their final year of high school, this impressive mobile application promises to take the fashion industry by storm. In a world of detrimental fast fashion consumption, ChangeRoom is the first apparel application of its kind to partner with sustainable clothing brands to bring a seamless shopping experience to life for a growing number of eco-conscious customers. It has even partnered with tech experts at Shopify to bring its vision to life.

Sustainable fashion isn’t the most accessible due to its price-point or visibility to younger, money-conscious consumers, but ChangeRoom is looking to partner with unconventional sustainable apparel companies such as thrift stores to enhance access.  

After winning a $5,000 pitch competition with Concept, ChangeRoom sought out the team at GH for more guidance and support with its venture.   

“GreenHouse has been so helpful in bringing our goals to life,” says Bhargava. “Being a part of the community has given us new ways to adjust our product for maximum social impact.”

Most recently, ChangeRoom has won the top prize from the Social Impact Fund, $2,500. The team plans to use the funding to increase its monthly active user base and expand its brand partnerships while working full-time on its venture during the summer.

GH understands how impactful these ventures will become for current and future consumers and looks forward to continuously supporting Sup Zero and ChangeRoom through bi-weekly mentorship.

Shift-work causes negative impacts on health, affects men and women differently

Shift-work and irregular work schedules can cause several health-related issues and affect our defence against infection, according to new research from the University of Waterloo.

These health-related issues occur because the body’s natural clock, called the circadian clock, can be disrupted by inconsistent changes in the sleep-wake schedule and feeding patterns often caused by shift work. To study this, researchers at Waterloo developed a mathematical model to look at how a disruption in the circadian clock affects the immune system in fighting off illness.

“Because our immune system is affected by the circadian clock, our ability to mount an immune response changes during the day,” said Anita Layton, professor of Applied Mathematics, Computer Science, Pharmacy and Biology at Waterloo. “How likely are you to fight off an infection that occurs in the morning than midday? The answer depends on whether you are a man or a woman, and whether you are among quarter of the modern-day labour force that has an irregular work schedule.”

The researchers created new computational models, separately for men and women, which simulate the interplay between the circadian clock and the immune system. The model is composed of the core clock genes, their related proteins, and the regulatory mechanism of pro- and anti-inflammatory mediators. By adjusting the clock, the models can simulate male and female shift-workers. 

The results of these computer simulations conclude that the immune response varies with the time of infection. Model simulation suggests that the time before we go to bed is the “worst” time to get an infection. That is the period of the day when our body is least prepared to produce the pro- and anti-inflammatory mediators needed during an infection. Just as importantly, an individual’s sex impacts the severity of the infection.

“Shift-work likely affects men and women differently,” said Stéphanie Abo, a PhD candidate in Waterloo’s Department of Applied Mathematics. “Compared to females, the immune system in males is more prone to overactivation, which can increase their chances of sepsis following an ill-timed infection.”

The study, Modeling the circadian regulation of the immune system: sexually dimorphic effects of shift work, authored by Waterloo’s Faculty of Mathematics’ Layton and Abo, was recently published in the journal PLoS Computational Biology.
