“We’re a suburban nation,” said Sasha Tsenkova, a professor of architecture, planning and landscape at the University of Calgary, who looked at our findings.
In all, 1,700 square kilometres have been added to the country’s nine biggest metropolitan areas since 2001. It’s as if the country’s urban areas have increased by three-and-a-half times the size of the island of Montreal.
And since urban sprawl (up 34 per cent) has progressed on average faster than population growth (up 26 per cent), each Canadian occupies, on average, more space, farther away from city centres. In 2001, residents of the nine largest centres occupied an average of 317 m2 of urbanized territory. In 2021, it went up by 19 m2, an area equivalent to one to two additional parking spaces for each inhabitant.
“Urban sprawl contributes enormously to greenhouse gas emissions,” said Tsenkova. “It has an economic, environmental and social cost.” Instead of building new neighbourhoods, we should intensify those that already exist and add services and shops within walking distance, according to experts.
There is no silver bullet solution when it comes to cybersecurity. New vulnerabilities are discovered every day and IT staff must win the cybersecurity battle every time, whereas attackers only need to win once to gain a foothold in an environment. So where do you focus your efforts to ensure your organization is staying protected? This blog will look at your cybersecurity defense in depth strategy.
Defense in depth is a well-known strategy amongst cybersecurity practitioners. This strategy utilizes layers of security controls to ensure that the confidentiality, integrity, and availability of information systems are maintained. Your organization will likely already have several layers of security controls in place, but you may still be wondering which controls are the most effective or would provide the best return on investment. Let’s look at the key elements of a cybersecurity defense in depth strategy.
Make sure students understand the concept of “Defense in Depth”: layers of security controls to ensure that the confidentiality, integrity, and availability of information systems are maintained.
“Whether your organization realizes it or not, you already have a fleet of security sensors deployed: your staff! ” They are indeed the first line of defense, but also the most likely to cause a problem. Why is this?
The article say “Some professors will have Zoom sessions to communicate, but the responsibility dynamic shifts a little bit, where although the school is very supportive, it’s all about the initiative from the student.” What does this mean?
How might you set up a business around online learning where you can help students navigate “responsibility dynamic shifts”?
“the algorithm will open up the six-year archive of cloudy Sentinel-2 imagery to all kinds of new analysis, from mapping trends in drought to tracking the extent of frost and snow cover.” How will this be useful?
If you can get six-years of archival data of almost daily satellite coverage for an area, what sort of business could you build around this?
A number of companies — including Flashfood, Too Good To Go and FeedBack — have entered the Canadian market billing themselves as an innovative way to simultaneously cut food waste and save money.
“They are becoming more popular because more and more consumers realise that savings occur more on the back-end of the grocery store experience,” said Sylvain Charlebois, director of the Agri-Food Analytics Lab and professor at Dalhousie University.
“There’s not a whole lot of promotions going on in stores.”
Too Good To Go, a Copenhagen-based company, made its mobile app available in Canada last year and operates in Toronto, Vancouver and Montreal so far.
“According to United Nations figures, a record 53.6m tonnes of electronic waste was generated worldwide in 2019 – up 21% in just five year – with mobile phones making up a significant part of this. What’s more, only 17% of electronic waste was recycled.” Why is it that otherwise earth-conscious people don’t seem to care when it comes to getting rid of their outdated technology?
Why is that people seem just fine, and indeed excited, to upgrade their phone every two years when there are phones like this around?
To help her and others who worry about their lack of green fingers, there has been a growth in the sale of hi-tech sensors for indoor plants – devices that you push into the soil next to them.
These sensors are usually solar powered and connect wirelessly by Bluetooth or wi-fi to a user’s smartphone and laptop. They show in real time if a plant has enough water or sunlight, and the correct temperature.
Ms Moeller uses a sensor made by German firm Greensens for some of her plants. It has more than 5,000 species on its app database.
“It gives me the opportunity to monitor… and now my plants look healthy,” says Ms Moeller, who gets sent regular notifications about how her plants are doing, and whether they need watering in particular.
