2023: surely the year for harder questions about the impact of our infrastructure on biodiversity.
For example, researchers in Idaho built a fake road to test out the impact of freeway noise on migrating birds.
“A third of the usual birds stayed away… those that stayed paid a price,” writes Ed Yong in his fabulous book Immense World on animal senses. The noises drowned out the sounds of their predators, so the birds had to spend more time looking for danger and less for food, so they put on less weight and were weaker for their migrations – which take every bit of energy the birds have.
And this didn’t include actual road effects from headlights, exhaust fumes, polluting run-off.
As Ed Yong says, more than 83% of continental USA lies within a kilometre of a road. There is nowhere else for the birds to go.
We have options to do something about this in our infrastructure, in a year we’re meant to be ‘building back better’.
Just replacing blue or white LEDS with red in, for example, parking lot lighting cuts down the impact of night light on insects. Sound-absorbing surfaces and barriers; slowing down traffic; quieter vehicles – all can immediately reduce noise pollution for animals such as owls and mice who depend on sound to catch or avoid being caught.
If 80% of humanity live under light-polluted skies and two-thirds of Europeans live in the noise equivalent of constant rain, it’s not great for people. But what Ed Yong brings out so brilliantly is how often we don’t even think about the different and miraculous sense worlds of other species, of whales and manatees and frogs and birds, and how very much worse it can be for them.
Is this the year to start taking seriously a problem we’ve only just begun to realise?
Immense World, Ed Young, 2022 – how other animals sense is truly mind-blowing.
Not everywhere in the world uses hedges. But Britain has about 500,000 km of hedgerow – despite losing half of them since 1945, as industrial scale farming has taken hold here. One of my very earliest memories is being driven through a patchwork, hedged landscape in the middle south west of England. And it was magic.
Hedges are not just fence-equivalents, worth the investment for that alone. They also store carbon, of course, as linear (if metre high) woodland.
“Hedgerows help slow down the runoff of water, guarding against flooding and soil erosion, and act as barriers to help prevent pesticide and fertiliser pollution getting into water supplies. Studies show they can improve the quality of air by helping trap air pollution.
“They are perhaps the largest semi-natural habitat in Britain, refuges for wild plants and corridors for wildlife to move through, often in barren farmland landscapes.” Paul Simons, the Guardian, 18 Aug 2021
For these reasons, the UK Climate Change Committee recommends planting 40& more hedgerows by 2050.
They are only semi-wild, of course, because they are trees manipulated (‘laid’) by humans, and so require effort, and skill. They are very definitely infrastructure.
In a previous post, there was a diagram showed how each of our ‘waves’ could also be conceived of as particles, embedding and building on each other. .This is our latest version, to capture the ideas of ‘grey assets’, as opposed to green and blue assets.
For the last 40 years the economic focus has been on growth.
And so infrastructure decisions have also focused on growth. But now this growth focus is changing as we realise the damage we are causing – and so asset management and infrastructure decision making needs to change, too.
We are now at a pivot point.
We have been at pivot points before. This is what Talking Infrastructure’s THE ASSET MANAGEMENT STORY is now documenting.
At each pivot point in Asset Management (the beginning of each wave), we have expanded our understanding of the world we operate in. Starting from simply maintaining and recording in Wave 1, we moved, in Wave 2 or Strategic Asset Management, to using this information to optimise decisions concerning our existing portfolios.
Then, in Wave 3, we look to take on a bigger role, infrastructure decision making, where we go out into our communities to work on whether the size and shape of our portfolio is what it needs to be. Wave 4 extends our understanding of our asset portfolios to the impact we are having on society and planetary health, and actively seeks to improve these impacts. The task in Wave 4 is to make all infrastructure decisions ‘future friendly’.
Wave 4 is the challenge that Talking Infrastructure was surely set up to address.
It is our most critical pivot point yet in asset management. This is the challenge that Talking Infrastructure CEO, Jeff Roorda, is leading at the Blue Mountains City Council where he is Director of Economy, Place and Infrastructure services. The city’s focus is on Planetary Health and Social Wellbeing. And we will be reporting what the City, and others with whom it is working, learns so that everyone can move in a saner direction than we may have done in the past.
