Exploring the Future of Saskatoon's Green Spaces: CALL TO ACTION

[reasonsforhope]

"In China, a landscape architect is reimagining cities across the vast country by working with nature to combat flooding through the ‘sponge city’ concept.

Through his architecture firm Turenscape, Yu has created hundreds of projects in dozens of cities using native plants, dirt, and clever planning to absorb excess rainwater and channel it away from densely populated areas.

Flooding, especially in the two Chinese heartlands of the commercial south and the agricultural north, is becoming increasingly common, but Yu says that concrete and pipe solutions can only go so far. They’re inflexible, expensive, and require constant maintenance. According to a 2021 World Bank report, 641 of China’s 654 largest cities face regular flooding.

“There’s a misconception that if we can build a flood wall higher and higher, or if we build the dams higher and stronger, we can protect a city from flooding,” Yu told CNN in a video call. “(We think) we can control the water… that is a mistake.”

Yu has been called the “Chinese Olmstead” referring to Frederick Law Olmstead, the designer of NYC’s Central Park. He grew up in a little farming village of 500 people in Zhejiang Province, where 36 weirs channel the waters of a creek across terraced rice paddies.

Once a year, carp would migrate upstream and Yu always looked forward to seeing them leap over the weirs.

This synthesis of man and nature is something that Turenscape projects encapsulate. These include The Nanchang Fish Tail Park, in China’s Jiangxi province, Red Ribbon Park in Qinghuandao, Hebei province, the Sanya Mangrove Park in China’s island province of Hainan, and almost a thousand others. In all cases, Yu utilizes native plants that don’t need any care to develop extremely spongey ground that absorbs excess rainfall.

He often builds sponge projects on top of polluted or abandoned areas, giving his work an aspect of reclamation. The Nanchang Fish Tail Park for example was built across a 124-acre polluted former fish farm and coal ash dump site. Small islands with dawn redwoods and two types of cypress attract local wildlife to the metropolis of 6 million people.

Sanya Mangrove Park was built over an old concrete sea wall, a barren fish farm, and a nearby brownfield site to create a ‘living’ sea wall.

One hectare (2.47 acres) of Turenscape sponge land can naturally clean 800 tons of polluted water to the point that it is safe enough to swim in, and as a result, many of the sponge projects have become extremely popular with locals.

One of the reasons Yu likes these ideas over grand infrastructure projects is that they are flexible and can be deployed as needed to specific areas, creating a web of rain sponges. If a large drainage, dam, seawall, or canal is built in the wrong place, it represents a huge waste of time and money.

The sponge city projects in Wuhan created by Turenscape and others cost in total around half a billion dollars less than proposed concrete ideas. Now there are over 300 sponge projects in Wuhan, including urban gardens, parks, and green spaces, all of which divert water into artificial lakes and ponds or capture it in soil which is then released more slowly into the sewer system.

Last year, The Cultural Landscape Foundation awarded Yu the $100,000 Oberlander Prize for elevating the role of design in the process of creating nature-based solutions for the public’s enjoyment and benefit."

reminder that fighting for climate solutions means fighting for public health.

switching to clean energy means less air pollution and significantly less deaths associated with fossil fuel extraction

green, localized, and walkable neighborhoods with accessible transport is good for physical, mental, social, and emotional health

cutting down the beef and dairy industries and eating more plant based (for those who can) is better for health of individuals

fighting for unionized labor in good, clean jobs means less stress in people's daily lives which leads to less stress-related illness and injury

Fight for your neighbors, fight for the planet

Building at great height requires a massive amount more material than a typical high-rise. The upper storeys of super- and megatall buildings – which often include hundreds of metres of unoccupiable ‘vanity’ height – are buffeted by ferocious wind loads, with any sway at all introducing enormous destabilising forces into the structure below. They are home to hefty services that raise water, coolant, people and air to great heights, and these heights must be offset by deep underground foundations. ‘If you’ve ever seen any Revit models [of London high-rises, there is pretty much as much concrete in those foundations as there is above ground,’ says Natasha Watson, an engineer at Buro Happold who leads the firm’s efforts to measure and reduce embodied carbon in its projects. Even in areas  with firmer ground than London, Watson explains, the awe-inspiring physics of skyscrapers has a huge material cost.

In an industry that is chronically lacking in transparency around its ecological, social and labour impact, it is difficult to find good data on the carbon footprint of skyscrapers. But the assessments that are available bear out the physics. Watson and her colleagues’ modelling shows that the efficiency of structural material usage, by floor area, drops above just three storeys. According to a 2015 study commissioned by the CTBUH, the whole life emissions of both energy use and materials for a 120m concrete and steel structure are nearly five times higher than those of its 60m equivalent. Who knows what the cost becomes at 600m? 

It is not yet possible to avoid this cost by using less ecologically destructive materials. Although some 100m-tall timber buildings are beginning to appear, they are nowhere near the 600m ‘megatall’ mark. According to Watson, finding a sufficient volume and quality of reused steel and concrete structural components for such a large, high-performance building would also likely be challenging.

Even at city level, the huge carbon cost of skyscrapers fails to outweigh any potential benefits that they might achieve from restraining urban sprawl. A study in npj Urban Sustainability in 2021 showed that the most carbon-efficient way for cities to grow is by developing densely built low-rise environments. The carbon cost of taller buildings is greater than carbon savings from restricted land use. This means that high-density low-rise cities such as Paris are more carbon-efficient than high-density high-rise cities such as New York.

There’s 2 brothers. In a city. But it’s 2 cities. And it was the best of times. And then a meteor hit. And it was the worst of times. And they ran as fast as they could, from an epoch of belief, and an epoch of incredulity, and giant cat monsters, and that’s when a giant tornado hit, and things got kicked into 12th gear, because they’re, they’re 2 brothers, you see, in 2 cities, and

"Chicago’s 82-story Aqua Tower appears to flutter with the wind. Its unusual, undulating facade has made it one of the most unique features of Chicago’s skyline, distinct from the many right-angled glass towers that surround it.

In designing it, the architect Jeanne Gang thought not only about how humans would see it, dancing against the sky, but also how it would look to the birds who fly past. The irregularity of the building’s face allows birds to see it more clearly and avoid fatal collisions. “It’s kind of designed to work for both humans and birds,” she said.

As many as 1 billion birds in the US die in building collisions each year. And Chicago, which sits along the Mississippi Flyway, one of the four major north-south migration routes, is among the riskiest places for birds. This year, at least 1,000 birds died in one day from colliding with a single glass-covered building. In New York, which lies along the Atlantic Flyway, hundreds of species traverse the skyline and tens of thousands die each year.

As awareness grows of the dangers posed by glistening towers and bright lights, architects are starting to reimagine city skylines to design buildings that are both aesthetically daring and bird-safe.

Pictured: Chicago's Aqua Tower was designed with birds in mind.

Some are experimenting with new types of patterned or coated glass that birds can see. Others are rethinking glass towers entirely, experimenting with exteriors that use wood, concrete or steel rods. Blurring lines between the indoors and outdoors, some architects are creating green roofs and facades, inviting birds to nest within the building.

“Many people think about bird-friendly design as yet another limitation on buildings, yet another requirement,” said Dan Piselli, director of sustainability at the New York-based architecture firm FXCollaborative. “But there are so many design-forward buildings that perfectly exemplify that this doesn’t have to limit your design, your freedom.”

How modern buildings put birds in danger

For Deborah Laurel, principal in the firm Prendergast Laurel Architects, the realization came a couple of decades ago. She was up for an award for her firm’s renovation of the Staten Island Children’s Museum when the museum’s director mentioned to her that a number of birds had been crashing into the new addition. “I was horrified,” she said.

She embarked on a frenzy of research to learn more about bird collisions. After several years of investigation, she found there was little in the way of practical tips for architects, and she teamed up with the conservation group NYC Audubon, to develop a bird-safe building guide.

The issue, she discovered, was that technological and architectural advancements over the last half-century had in some ways transformed New York City – and most other US skylines and suburbs – into death traps for birds...

At certain times of day, tall glass towers almost blend into the sky. At other times, windows appear so pristinely clear that they are imperceptible to birds, who might try to fly though them. During the day, trees and greenery reflected on shiny building facades can trick birds, whereas at night, brightly lit buildings can confuse and bewilder them...

Pictured: A green roof on the Javits Convention Center serves as a sanctuary for birds.

The changes that could save avian lives

About a decade ago, Piselli’s firm worked on a half-billion-dollar renovation of New York’s Jacob K Javits Convention Center, a gleaming glass-clad space frame structure that was killing 4,000-5,000 birds a year. “The building was this black Death Star in the urban landscape,” Piselli said.

To make it more bird friendly, FXCollaborative (which was then called FXFowle) reduced the amount of glass and replaced the rest of it with fritted glass, which has a ceramic pattern baked into it. Tiny, textured dots on the glass are barely perceptible to people – but birds can see them. The fritted glass can also help reduce heat from the sun, keeping the building cooler and lowering air conditioning costs. “This became kind of the poster child for bird-friendly design in the last decade,” Piselli said.

The renovation also included a green roof, monitored by the NYC Audubon. The roof now serves as a sanctuary for several species of birds, including a colony of herring gulls. Living roofs have since become popular in New York and other major cities, in an inversion of the decades-long practice of fortifying buildings with anti-bird spikes. In the Netherlands, the facade of the World Wildlife Fund headquarters, a futuristic structure that looks like an undulating blob of mercury, contains nest boxes and spaces for birds and bats to live.

The use of fritted glass has also become more common as a way to save the birds and energy.

Earlier this year, Azadeh Omidfar Sawyer, an assistant professor in building technology in the Carnegie Mellon School of Architecture, working with student researchers, used open-source software to help designers create bespoke, bird-friendly glass patterns. A book of 50 patterns that Sawyer published recently includes intricate geometric lattices and abstract arrays of lines and blobs. “Any architect can pick up this book and choose a pattern they like, or they can customize it,” she said.

Pictured: The fritted glass used in Studio Gang’s expansion of Kresge College at the University of California, Santa Cruz, depicts the animals in the local ecosystem.

Builders have also been experimenting with UV-printed patterns, which are invisible to humans but perceptible to most birds. At night, conservationists and architects are encouraging buildings turn off lights, especially during migration season, when the bright glow of a city skyline can disorient birds.

And architects are increasingly integrating screens or grates that provide shade as well as visibility for birds. The 52-floor New York Times building, for example, uses fritted glass clad with ceramic rods. The spacing between the rods increases toward the top of the building, to give the impression that the building is dissolving into the sky.

Gang’s work has incorporated structures that can also serve as blinds for birders, or perches from which to observe nature. A theater she designed in Glencoe, Illinois, for example, is surrounded by a walking path made of a wood lattice, where visitors can feel like they’re up in the canopy of trees.

Pictured: The Writers Theatre, designed by Studio Gang, includes a walking path encased in wood lattice.

Rejecting the idea of the iridescent, entirely mirrored-glass building, “where you can’t tell the difference between the habitat and the sky”, Gang aims for the opposite. “I always tried to make the buildings more visible with light and shadow and geometry, to have more of a solid presence,” she said.

Gang has been experimenting with adding bird feeders around her own home in an effort to reduce collisions with windows, and she encourages other homeowners to do the same.

“I’ve found that birds slow down and stop at feeders instead of trying to fly through the glass,” she said.

While high-rise buildings and massive urban projects receive the most attention, homes and low-rise buildings account for most bird collision deaths. “The huge challenge is that glass is everywhere.” said Christine Sheppard, who directs the glass collisions program at the American Bird Conservancy (ABC). “It’s hard to know what I know and not cringe when I look at it.”

Tips for improving your own home include using stained glass or patterned decals that can help birds see a window, she said. ABC has compiled a list of window treatments and materials, ranked by how bird-safe they are.

Whether they’re large or small, the challenge of designing buildings that are safe for birds can be “liberating”, said Gang, who has become an avid birdwatcher and now carries a pair of binoculars on her morning jogs. “It gives you another dimension to try to imagine.”"

behold, the very first concept arts for spectre city online! i think i'll try to post concepts regularly to show my progress and also to challenge myself i guess? this is for the townspeople/playable characters - i'd imagine them to be normal kids with pumpkin heads, who can replace them in a 'carving ritual' (think like pixie hollow minigames) for different designs. maybe they put other stuff on their heads, like fruit, and there could be limited edition fruit for holidays? another option for playable characters would be ghosts, but i feel like theyd have less customisation choices. i really want faceless characters as well, because i think one of the core parts of halloween is the fact that you're not really 'yourself' - you could be in a mask, and nobody would recognise you, and you can be whoever you want. for outfits, i imagine costumes based off a variety of halloween monsters and creatures - the scaryness of the outfit would affect your 'tricking' (battle system) performance, while the cuteness or sillyness of the outfit would affect your 'treating' (trading/selling your stuff with npcs/other players) performance.
