Reimagining anti-graffiti

Decades of graffiti in a village underpass

by Mateja Mihinjac


This blog was inspired by a recent trip to my home village of 6,000 residents. Ever since I can remember, every few months the graffiti in the railway underpass near my house is painted over and the broken lights fixed. Shortly after fixing, the signs of vandalism reappear and a few months later the graffiti reappears. This has been occurring for the last 30 years.

GRAFFITI MANAGEMENT PROGRAMS

At the start of my criminology career, I learned that rapid graffiti removal programs were the most efficient way to address the problem because they deny graffiti offenders or “artists” the reward of having their work seen by others. In the 1980s, the famous Broken Windows Theory began with one such program in the New York City subway system’s Clean Car Program – graffiti was removed and vandalism repaired.

Through subsequent research and practical work I learned this approach might not be very effective and cost-beneficial as it is costly, may lead to displacement, fails to account for various motivations in the offenders, and generally fails to permanently eliminate the problem.

Since then other approaches appeared for addressing graffiti. One approach focuses on anti-graffiti materials and surfaces, increased penalties for “offenders”, and community clean-ups. Another approach designates graffiti walls and education or mural programs for offenders, such as the successful program for talented graffiti artists described in on this blog site by our team member Anna Brassard.

While some cities successfully integrate both approaches, other cities are more polarized in their graffiti management approaches. For example in Ottawa, city leaders maintain a strict no-graffiti policy apart from designated legal graffiti walls and murals under the City’s mural program.

Street art is a regular feature of urban life throughout the world
Conversely, the mayor of the Colombian capital of Bogota has decriminalized graffiti after a tragic event in 2011 when a young artist was fatally shot. Apart from designated off-limit surfaces, graffiti artists in Bogota are free to express their creativity across the city. Graffiti is now integrated into city life and, interestingly, has become a major attraction for visitors.

I don’t argue for one approach over another since different contexts require different solutions. However, if an approach remains unsuccessful over a number of decades, such as in the railway underpass in my home village, it is time to consider alternative strategies. One missing link, however, is the limited voice of local community members.

NEGOTIATED CONSENT OR ZERO TOLERANCE?

In her reflection on developing a graffiti strategy for the city of Melbourne, criminologist Alison Young recommended against the city’s zero-tolerance approach with increased criminalization of graffiti artists, the approach which local government had adopted at the time.

She argued for self-regulation where property owners and local public would have a say in the image and identity of their local part of public space by either retaining it or by requesting the local government to remove the newly emerged graffiti. The thinking was that if local communities were given an opportunity for such self-governance, they might develop a greater sense of ownership and care for the local environment.

The Melbourne strategy has worked - today the city has a successful street graffiti program receiving world-wide acclaim. That success has turned into a major tourist attraction and economic success story for Melbourne including the popular Melbourne Street Art Tours by local tour companies and the annual Melbourne Stencil Festival.

Since 2010 the city has applied a hybrid approach where they now include the voice of business owners in deciding whether graffiti should be retained.

Melbourne provides an innovative answer to the question of whether we should eliminate graffiti, accept it, or channel freedom of expression in a positive direction for the artists and local communities. Despite a plethora of graffiti management practices, one thing is certain: graffiti is here to stay.

Reducing homelessness - An Australian example (Part 1)

The future of homelessness is in our hands - photo courtesy of Tiny Homes Foundation

By Mateja Mihinjac

In 2008 the Australian Government released its first White Paper on homelessness in which it announced a plan to cut homelessness in half and house all rough sleepers (a British term for those sleeping in the street) by 2020. Seeing little progress, the leading Australian charities have jointly committed to reaching this goal by 2025.

However, one of the major reasons behind homelessness is rarely discussed - housing affordability.

SCOPE OF THE PROBLEM

Australia is one of the world’s wealthiest nations and it seems unacceptable that it cannot provide affordable housing to all citizens when a sizable number of homes remain unoccupied. Yet, in 2016 the number of those experiencing homelessness in Australia on any given night was estimated at 105,000.

Exact homeless figures are always difficult to estimate, but this amounts to around 0.45% of the Australian population, a national figure that has remained relatively stable since 2011. For comparison, England’s estimates are around 275,000 (0.5% of population) while the US estimates 564,708 (0.2% of population).

To make matters worse, concentrated homelessness has increased in major city downtown areas in spite of a slight downward trend around the world.

Rising numbers of homeless people are concentrated downtown  

THE PARADOX OF PUBLIC SPACE

The homeless frequently occupy public spaces of city centers which offer them safety and access to resources. Yet, as with other cities around the world like Denver and Miami, some Australian cities employ social cleansing by removing homeless groups or banning homeless camps as bad for tourism even though homelessness is not illegal.

For example, the Melbourne Mayor has recently announced a proposal for a complete ban of rough sleepers in the city. These practices displace the homeless to peripheries of cities, pushing them farther away from much-needed services thereby reducing their prospects of ever resolving homelessness. We can do much better!

Shining light onto LEDs - disturbing findings


Fly into any major city at night and you’ll notice vast swaths of bright white lights replacing the yellow hue from high-pressure sodiums, once the preeminent lord of night lighting across the urban fabric.

The white light is from LEDs - light emitting diodes - and cities are installing them in an implementation tsunami. They are cheaper and they are brighter, but I have been bothered by their excessive glare and, during our night site visits, I always warn students about the lack of research on LED and human behavior. Over the years I’ve blogged about sodiums and Randy Atlas has guest blogged here on LEDs. But research has been scant.

Until now! And the early results are worrying.

AMERICAN MEDICAL ASSOCIATION

The American Medical Association has released a statement condemning the health effects of LED street lighting.

The AMA identifies two concerns:

  • First, the bright glare is caused from the wavelength and color rendition from LEDs. Apparently the high intensity of LEDs emit large amounts of blue light that appears white. This causes a glare problem worse than conventional street lights and it’s why the light dispersion from LEDs is so difficult to control, even with cutoff shields. Says the AMA: “Discomfort and disability from intense, blue-rich LED lighting can decrease visual acuity and safety…creating a road hazard.”

  • Second, it also turns out that the blue-rich LED streetlights suppress melatonin levels and people end up with disturbed sleep cycles. Says the AMA: “It is estimated that white LED lamps have five times greater impact on circadian sleep rhythms than conventional street lamps.” In large studies the AMA says this causes “reduced sleep times and impaired daytime functioning”. Not good.

Obviously, the AMA studies are not the final word. For example, the blue from LEDs can be controlled.

SOLUTIONS

The lighting industry, understandably, is not happy with the AMA conclusions. One source says “As with any new technology, there are a lot of unknowns that only time will be able to tell what the results/answers will be.”

That is the same thing we have been saying about LED lights from the beginning. In the budget-saving rush to install LEDs we know very little about the behavioral, social and medical consequences from these new light technologies.

Students of CPTED know that lighting research regarding safety is based on quantity, not quality. I have yet to read a single study on light source quality and crime related behavior. This knowledge gap isn't limited to LEDs, we also have inadequate qualitative information on halide or sodium light sources.

Until we do, it’s probably best to look for successful cities with exceptional lighting, such as Melbourne, Australia, and see what they do right.

Discovering the city at night

Uplighting sidewalk tree canopies with green tint - all photos from Ian Dryden

A few months ago I met award-winning industrial designer Ian Dryden from the city of Melbourne, Australia. He taught me about Melbourne's street lighting program. Given the links between fear and street (in)activity, this is a very big deal.

Most cities get poor grades for night lighting. Melbourne gets an A.

Melbourne has an incredibly active downtown night life. It wasn't always. One long-term resident told me it was once a waste-land with few people daring to walk dark downtown streets. When the city changed direction and chose to attract an evening crowd to socialize in a safe, positive way, designers and planners stepped up.

Ian and his colleagues were among them. Melbourne's public lighting program is sophisticated. It creates both a luminous and carbon neutral city, no small feat with current energy costs.

They light parks, tram stops, news stands, benches, and sidewalks. They string interesting blue (and energy efficient) LEDs above intersections. Where most cities inadvertently obstruct street lights with tree canopies, Melbourne embellishes them with tinted uplighting.

This week the 2014 Australian Smart Lighting Summit is in Melbourne and they get to celebrate among lighting peers. They should. Congratulations!

Graff war in the streets of Melbourne




My architect friend Frank Stoks sent me a news clip of an emerging graff war in Melbourne.  Frank is a well-known CPTED expert in New Zealand. Back in the 1980s questions from his PhD thesis comprised the basis for the Toronto's Women's Safety Audit - now the United Nations Safety Audit.

Melbourne Australia is a remarkable city of culture and walkability. Our SafeGrowth teams continue their exceptional work in 4 neighborhoods, recently highlighted at a recent Australian criminology conference. Melbourne is also known for its vast array of street art and graffiti, particularly in laneways, much of it under city supervision mentioned in an earlier blog, Eyes Wide Open, Magnificent Melbourne.

Now, according to this news clip, a graff war has broken out between the street artists commissioned by the city to create the murals and some culture jamming taggers who are not. Says one street artist: "The council is commissioning the work to stop tagging and not including the guys who have come from the graffiti background, so they're alienating the scene."

Eyes Wide Open - Magnificent Melbourne


Love locks on pedestrian bridge

Among her many contributions to urban culture - especially in regards to crime - Jane Jacobs shone a light on what she called the subtle "ballet of the street". Hers was the gift to look and see what locals and city officials actually do to their pubic spaces and how they treat or mistreat them.

The ability to see with Eyes Wide Open is the cultivated skill of looking with an uncluttered mind unswayed by prejudices (as impossible as that seems).

This week we introduced SafeGrowth planning to Melbourne, Australia. We found limitless opportunities to practice Eyes Wide Open on the downtown streets of that magnificent city: subtle feasts like socks knitted over road barriers (who came up with yarn bombing, anyway?); sublime feasts like personal love locks locked on a pedestrian bridge.

Like pennies in a fountain, love locks just show up 
Knit graffiti? Traffic barrier's get cold too!
Melbourne's rich array of urban micro-tweaks show up to a much greater extent than most other places I've seen. I suspect it's partly why so many downtown streets buzz day and night.

No doubt crime occurs downtown. We watched cops arrest at least one inebriated troublemaker. Plus three of our SafeGrowth teams are tackling crime and fear issues downtown.

City designers use indirect blue bench lighting - subtle yet aesthetic
Yet from the library staircase that university students control like protective hens to the graffiti laneways that show up on tourist maps (this is, after all, a city-of-laneways), downtown Melbourne epitomizes the diversity Jacobs so loved on vibrant public streets.
