How much more evidence do we need to invest in green spaces?

Sheffield green space
An abundance of good, and a case for investment: in Sheffield woodlands, public parks, allotments and industrial heritage nestle cheek-by-jowl in the Porter Valley.

We know green spaces are good for us. The evidence is overwhelming. So why don’t we invest in what we know to be healthy and helpful, when we can find £522 million to subsidise people who want a meal out?

 In case there’s any doubt about the evidence, earlier this year a team at Sheffield Hallam University produced a report, Space to Thrive, which reviewed nearly 400 recent academic papers on the social benefits of urban parks. As well as supporting physical and mental health, which you’d expect, parks also play an important community role, bringing people together and enabling people to feel more involved in society.

But we also know that parks and green spaces are underfunded. A parliamentary inquiry three years ago found they were at a ‘tipping point’ of decline in England. So why are they considered less important than roads (£27.4bn investment over five years in England), private houses (£3.8bn diverted to the better-off through the suspension of stamp duty in 2020-21), or prisons (£2.5bn to create an extra 10,000 prison places)?

‘We want to invest, but we can’t’

It’s not as if local councils, which are responsible for most urban parks and many other green spaces, think parks are unimportant. But between 2010 and 2017/18 central government funding for English local authorities fell by 49.1% in real terms, and spending power (taking locally raised resources into account) fell by 28.6%. There is no statutory duty for councils to create or maintain parks.

Even this year, when the importance of parks has been spotlighted during the Covid-19 lockdown because they were among the very few public places people could use, local authorities are still discussing how they can save more money from parks budgets. 

And even when there is a chance to invest, council officers often feel disempowered and unable to make the case. In recent research in Sheffield we found a series of ‘logics of inaction’, justifiable reasons for not making the improvements council staff knew would be helpful. 

Unsurprisingly, the main logic was a financial one – people believed they would not be able to justify investment compared with actions generating a perceived immediate economic benefit, like mending roads, or where there was a legal duty attached, such as social services. But we also found people were institutionally disempowered: ten years of austerity have instilled a ‘finance says no’ culture within local government. 

Evidence-seeking as myth and ceremony

A common expression of this culture of disempowerment is to seek more evidence to justify investment, but then to argue that the evidence is insufficient. One parks professional we interviewed put it like this: 

‘…what we need to do is be better and savvier at using statistics, using the work of yourself and research in the city to say, Parks and Countryside have got so much x, it provides y, the benefits are pounds and economic savings.’

But in further discussions, another made the revealing comment that ‘I don’t even try anymore’. In a new book published by Springer Nature, I and my co-editor Nicola Dempsey argue that evidence-seeking has become an excuse for kicking the can down the road, deferring commitment on the basis that evidence is still not good enough.

In Naturally Challenged: Contested perceptions and practices in urban green spaces, we investigate the ‘logics of inaction’ affecting suggested investments. Drawing on John W Meyer and Brian Rowan’s classic study in organisational theory showing how organisational structure is often a result of ‘myth and ceremony’ which services the purpose of legitimising activities, we consider evidence-seeking through the same lens. 

While organisations engage actively in the search for appropriate evidence, the evidence legitimises a process of decision-making that does not require evidence to be acted upon. Evidence-seeking becomes a justificatory activity. We argue:

‘The myth of evidence-based policy … enables proposals to be rejected on the basis of insufficient evidence, effectively masking the politics of decision-making. A concern with “what works” and “good practice” provides an appearance of logical inevitability for what is actually a political choice.’

Where does that leave the case for investing in parks and green spaces? In our view, the evidence is good enough: it is the consequent action that has failed.

We are on the brink of a spending review that will set priorities in the UK for half a decade or more. In the run-up to that review, professionals, academics and campaigners are amassing the evidence and making the case for serious and significant investment in green space. The National Trust, for example, says we need a £5.5bn fund to improve green spaces and create new ones. 

If the spending review does not deliver, it won’t be for lack of evidence. It will be a political choice. And if the political choice is for prisons rather than parks, we should ask what that tells us about our priorities.

  • There will be an online launch of Naturally Challenged on Thursday 8 October at 5pm. To join the discussion please book tickets via Eventbrite.
