Without the state

Heading for retirement

This blog is now retired. It will stay in being, but will have no further updates. Any future writing will be here (on art and art related matters) or here (everything else)

Changes ahead

This blog has been pretty moribund for a while, largely because my original intent for it is no longer relevant. I'm going to recast it over the next few weeks, once I work out how to remap the domain, as a simple personal blog. Whether that will mean I post more frequently, remains to be seen. This will only be the second such change since I started it in 2003, so not a bad achievement.

Do we really have too much development in the UK?

Think your country is crowded? These maps reveal the truth about population density across Europe

It’s often said that England is the most densely populated large country in Europe – typically in discussions about the nation’s rising population, and the growing strain on public services. But it’s not true.

With 426 people per km², as of 2016, England is densely populated when compared to most other European countries. But it’s not as densely populated as the Netherlands, where there were 505 people per km², or a much poorer country such as Bangladesh, where there were 1,252 per km².

The truth about how crowded your country is. World Bank

Yet simply dividing the number of people by the land area of a country is not always the best way to understand population density. Consider a country such as Russia, where urban density is high, but there are vast swathes of empty land. The figures will tell you density is very low (eight people per km²); but this it not what most people in Russia experience in their daily lives. The same is true of Australia, Canada and other large, highly urbanised nations.

That’s why I set out to understand the topic in more depth, using alternative measures of population density. I looked at 39 countries across Europe and came up with a set of statistics to help us understand settlement patterns in a more nuanced way. If you are interested in looking at this issue globally, I recommend Duncan Smith’s World Population Density interactive map, or the World Bank’s data comparison tool.

A bird’s eye view

To begin with, I took Eurostat’s population density grid data for 2011 and mapped it. This divides Europe into areas of 1km², and then gives a population count for each area, so that we can compare like-with-like across Europe. As you can see from the map, it provides a good overview of where people live, and where they don’t live: notice the sparse settlement pattern in the Alps or northern Scandinavia, or indeed much of Spain.

European population density. Data: Eurostat. Mapping: by the author

This bird’s eye view helps us to understand the wider context. For example, we can see an area of high population density extending in a rough arc from north-west England down to Milan, with a little break in the Alps. This is the so-called “blue banana”, or dorsale européenne (European backbone), identified by French geographer Roger Brunet in 1989, and it is home to more than 110m people.

But we can get further clarity still by honing in on “built-up” density, which takes into account only those 1km² areas with people living in them. I call this figure “lived density”, since it provides a way of seeing the kinds of population densities that people experience in their day-to-day lives, within built-up areas.

The Spanish distribution

A good way to understand this measure is to look at Spain. It has a population density of 93 people per km², giving the impression of a sparsely populated country. This is borne out in the map, where much of Spain appears to be empty; much more so than any other large European country.

The reasons for this date back to Medieval times, as Daniel Oto-Peralías at the University of St Andrews has explained. Yet characterising Spain as a sparsely populated country does not reflect the experience on the ground – as anyone who knows Barcelona or Madrid can tell you.

Spain contains within it more than 505,000 1km squares. But only 13% of them are lived in. This means that the “lived density” for Spain is in fact 737 people per km², rather than 93. So even though the settlement pattern appears sparse, people are actually quite tightly packed together.

In fact, Spain could claim to be the most densely populated major European country by this measure, despite its appearance on the map. This also helps explain why Spain has the most densely populated km² in Europe; more than 53,000 people inhabit a single 1km² area in Barcelona. France also has an area with more than 50,000 people in a single km², in Paris.

Barcelona from above: possibly the most densely populated km² in Europe. Author

There are 33 1km² areas across Europe with a population of 40,000 or more: 23 are in Spain, and ten are in France. England’s most densely populated km², in West London, has just over 20,000 people in it. Globally, the highest figure is close to 200,000, in Dhaka, Bangladesh.

See for yourself

When we look at “lived density” across Europe, it’s fair to say that England is a densely populated country – but it still sits behind Spain and the Netherlands on the list of major European nations, and below the microstates of Monaco, Andorra and Malta. The lived density figure for the Netherlands is 546 people per km², compared to 531 for England, 204 for Wales, 200 for Scotland and 160 for Northern Ireland.

Although these population numbers are a little dated now (they are based on 2011 data), they can still demonstrate how population density figures might differ from what we experience in our day-to-day lives. Arithmetic population density measures can be useful, but on their own they don’t always help inform public debate, or match up with our perceptions of urban density.

I have provided the data for all 39 countries, where available, so you can compare the figures for yourself. By using a more sophisticated measure, we can gain a more nuanced perspective of settlement patterns and relative densities and, hopefully, better capture the reality on the ground in towns and cities.

Note: the final column shows how many 1km cells have people in them, but within that the level of density also varies, so this is not a “percent urbanised” measure.

Making hardware 'open source' can help us fight future pandemics - here's how we get there

Making hardware 'open source' can help us fight future pandemics - here's how we get there

In factories and industrial estates across the world, exceptional efforts are being made to ensure hospitals have ventilators, and logistics firms have freezers and refrigerators. Behind the scenes, this manufacturing drive has been taking place on an epic, unprecedented scale. In some places, it’s also been horrendously inefficient.

Some of that inefficiency is only to be expected. Manufacturing responsively at such short notice was always going to be messy. But many of the hardware hold-ups we’ve witnessed – from production line bottlenecks to parts shortages – could be avoided in the future by applying an “open source” ethos to the world’s production of hardware.

Open source design is a form of collective intelligence, where experts work together to create a design that anyone has the legal right to manufacture. The software industry has long shown that “open” collaboration is not only possible, but advantageous. Open source software is ubiquitous, and the servers that power the internet itself are largely run on open technology, collaboratively designed by competing companies.

Early in the pandemic, and in recognition of the global emergency that was unfolding, dozens of the world’s largest companies did actually sign up to the “Open COVID Pledge”, promising to share their intellectual property to help fight the virus. On a smaller scale, more than 100 project teams set out to create and share “open” ventilator designs that could be produced locally, helping address the pressing need for ventilators around the world.

Unfortunately, neither of these initiatives succeeded in producing ventilators at the rate required by stretched hospitals in the early weeks of the pandemic. After examining existing attempts to share the intellectual property of machines, our recent paper concludes that projects must be open from the start in order to make a success of open hardware. Everything from the first doodle on a napkin to the detailed calculations that verify safety must be available if other experts and manufacturers are going to participate in the design.

The road to open hardware

Producing hardware through open collaboration may be daunting. As opposed to the entirely virtual collaboration required for software development, hardware development needs physical parts – raw materials and machinery. It needs testing facilities and engineers to perform stress tests and safety checks.

There are promising signs that these challenges can be met. The RepRap 3D printer project has brought low cost 3D printing to a wider audience, making affordable prototyping possible at a distance. Meanwhile, the CERN White Rabbit project has shown that even the complex electronics that control the Large Hadron Collider can be developed as as open source hardware. But, to be efficient we need better work flows for collaboration – systems to help organise the distribution of tasks and responsibilities on collaborative hardware projects.

The journey from prototype to production is much more difficult, and less exciting, than the technical challenge of prototyping a device. Manufacturers must comply with international standards to ensure quality and manage risk related to their products. This is especially true of medical hardware, upon which lives depend. A key challenge for open hardware will be to achieve this certification in the same way that private companies do today.

Under current regulations, no matter how impressive and safe, ventilators constructed in volunteer maker spaces cannot be certified for medical use. But for equipment which is less strictly regulated, like face shields, open hardware is currently being leveraged successfully.

Achieving similar successes with high-tech medical devices will require organisations that are built to manufacture from open designs – dynamic factories, for instance, which will be responsive to global emergencies. It takes time to establish these organisations. But we can’t afford to wait for the next emergency: we should begin creating them today, in preparation for the next pandemic.

Of course, finding sustainable business models for open hardware is a challenge: can a system be created which shares intellectual property for free while helping designers and manufacturers profit? In one sense, open hardware has an advantage here: people are used to buying products, where online consumers are accustomed to using software for free.

Nonetheless, it’s likely that setting up an open hardware manufacturing ecosystem will need public funding, or investor funding buying into non-traditional business models. This would follow the trajectory of the internet, which began life funded by public institutions and is now home to the world’s biggest private enterprises.

Closer inspection

We’ve experimented with our own open hardware project to help us understand how the future of collaborative hardware might look. Our OpenFlexure microscope is designed to be manufactured at low cost in sub-Saharan Africa, to be used for malaria diagnoses. We’ve probably spent more time designing the processes that help us share our knowledge effectively than designing the microscope itself.

In the short term, this slows our progress. In the long term, we expect that manufacturers anywhere in the world will be able to understand our design and adapt it to their local context. As these processes become further standardised, sharing designs for production will become increasingly simple. The final and most ambitious phase of our project will be working with manufacturers to produce microscopes certified for medical use – a huge step towards open source medical hardware we’d need to better fight a future pandemic.

Humanity already knew how to make ventilators decades before this pandemic hit. What was lacking was the access to this knowledge, the skills to work together on adapting a design, and the logistics to rapidly scale the manufacturing of complex machinery. It will take years to address these issues. Starting that process today will help us tackle global emergencies more dynamically and efficiently in the future.

Democracy is not a one time event.

The idea that democracy stops when you get the decision you like is getting more prevalent unfortunately. I say that regularly in response to comments on Facebook, although it never seems to get through. Only yesterday some ignorant low life tried to tell me I'm refusing to accept a democratic decision because I am critical of St Boris. The same low life also told to go to Europe if I didn't like it here.

I'm 74. I was born here, and I have lived here all my life. My father was born here and served in North Africa in WW2. He was nearly killed in Sicily. In a bizarre way that could well have saved his life, since his regiment took part in the Normandy Landings. My Grandfather was born here and served in France in WW1. He was injured too but survived. My uncle was born here and took part in D-Day. I could go further back too, so I’m not going to have some ignorant #### (insert your own choice of epithet – this isn’t so far a sweary blog) try to tell me I don’t belong here.

The reality is the opposite. The behaviour of this buffoon (on this occasion I don't mean Boris Johnson) is not democratic. It is not patriotic. It is a betrayal of everything my Father, Grandfather and Uncle put their lives on the line for. It is a betrayal of everything he claims to be standing for! It is him and people like him who are undermining democratic processes. It is him and people like him who are undermining the rule of law. It is him and people like him who are enabling and encouraging the growth of racism and xenophobia.

Do not let them get away with it.

Challenge them at every opportunity.

Do not give up.

Another really worrying aspect is the overlap between Brexiters and the COVID19 deniers. It isn't 100% by any means, but enough to be concerned not just about our political and economic future, but literally about our very existence. I've no doubt that we will eventually got on top of this Pandemic, but we also need to learn from it, because there will be another one.

There is little sign though of any capacity to think rationally and logically in either the loudest Brexiters or the COVID19 deniers so the chances of any learning taking place are slim. (It occurs to me that the only Flat Earther I've ever come across in the wild was also a Brexiter...)

A final story.

Ten years after my father was nearly killed in Sicily he almost died again, seriously injured in an industrial accident that with hindsight was probably due to cutting corners by his employer. Leaving the EU also means leaving the umbrella of their worker protection and Health and Safety rules. Tories have already started demanding we cut back on them and on environmental standards.

Don't let them have their own way.

Past generations fought to get us here. We owe it to future generations to go forward, not back to some fantasy of the Empire.

Public housing needs radical reform: here's how - republished from 'The Conversation'

Public housing needs radical reform: here's how

Britain’s housing system is well and truly broken. House-builders sit on land already granted planning permission and drip-feed the market to keep supply low and prices high. Despite the coronavirus crisis, house prices continue to soar, excluding most from ever reaching onto the property ladder.

Tax subsidies help speculative landlords exploit “generation rent”, who face a future far less secure or prosperous than that of their parents – or even their grandparents. As the welfare state is hollowed out, property assets replace retirement benefits, deepening deprivation and inflating property bubbles.

Widening inequalities collide with privatisation of public housing to exacerbate the homelessness crisis – despite thousands of homes lying empty across the country.

The UK’s housing problems are also grossly unevenly distributed. In economically depressed regions such as Liverpool, where I’m based, the state has been demolishing “obsolete” houses owing to “housing market failure”.

Yet only a few hundred miles away lies the epicentre of the property boom, London, where demand and financial speculation are so intense that local authorities engage in the creative destruction of ex-council estates. Thousands of tenants are displaced, often out of London, to clear sites for lucrative redevelopment as private flats with minimal affordable housing.

In both London and Liverpool – two extremes of Britain’s polarised housing market – activists have been busy re-imagining the future of public housing. One way this is being explored is through the use of community land trusts (CLTs), a form of collective ownership of land for affordable housing and other community uses, innovated in the 1960s American civil rights movement. I’ve been studying them over the past decade and recently published a book on the topic.

In London, led by East London CLT in Tower Hamlets, the CLT model has been used to contest the adverse effects – gentrification and displacement – of housing markets becoming “too hot”.

In Liverpool, a city where housing markets are “too cold”, having lost close to half its population in the second half of the 20th century, communities facing forced eviction and the state-funded demolition of their neighbourhoods have come together to campaign for CLT alternatives. Granby Four Streets and Homebaked are the country’s very first to pioneer the model for inner-city regeneration in contexts of urban decline.

Community alternatives

Granby Four Streets won the Turner Prize in 2015 – the first architectural project ever to do so. The award recognised the creative work of architects Assemble in bringing residents together in a democratic do-it-yourself rehabilitation process – what they call “community homesteading”.

This built on years of residents’ hard graft – and creative craft – to resist the bulldozers since the 1990s and transform their neglected neighbourhood into a horticultural wonderland, with street planters, vegetable plots, climbing flowers, garden benches and artistic murals; hosting a popular street market once a month.

Such guerrilla gardening was inspiration for a vision to establish a CLT in 2011 to restore derelict properties as decent affordable homes. Some were too dilapidated to save, transformed instead into a beautiful Winter Garden with subtropical plants, an artist studio and community meeting house.

This is about more than just bricks and mortar. The CLT is revitalising Granby’s struggling local economy through providing a permanent home for the street market, creating space for new businesses and community enterprise, providing new jobs as well as public space and community facilities for residents to engage in festivities and the collective management of their neighbourhood.

On the other side of the city, right opposite Liverpool Football Club, is Homebaked. This started life as a public arts project funded by the 2010 Liverpool Biennial called “2up2down”, which invited residents to re-imagine the terraced house.

 

Having successfully campaigned to save the local bakery and its terraced row from demolition, 2up2down evolved into Homebaked CLT to take on the ownership of the buildings and bring the bakery back into use. Plans are now afoot to renovate the terrace into cooperative housing and, on the ground floor, provide space for community enterprise, including their sister organisations Homebaked bakery co-op and Homegrown, a food growing and beer brewing collective. All of this is part of a long-term vision to democratically transform the neighbourhood.

Stronger foundations

CLTs such as Granby and Homebaked provide an inspiring blueprint for reconstructing public housing on stronger social and economic foundations.

They are legally incorporated with an “asset lock” which protects the land from being sold off and ensures that all surpluses from renting buildings get reinvested for community benefit. They are governed democratically through a trust structure with board members elected by the wider CLT membership, open to all local residents.

This also enables a public-common partnership approach with local authorities. In return for public land transfer and development expertise, CLTs make their permanently affordable homes available to local people in need.

But Granby and Homebaked remain artistic exemplars – too few and far between to make a huge difference to widespread housing problems. These extraordinary practices need to be replicated across Liverpool, London and beyond through radical new initiatives, so they become more ordinary features of public housing.

Learning from Liverpool

Public housing in the UK is witnessing a revival. Tight borrowing constraints imposed on councils have been loosened to enable the construction of new council housing for the first time in decades.

Yet it is vital that local authorities don’t repeat past mistakes. Bureaucratic and paternalistic management of council estates and the undemocratic commissioning of alienating designs, unresponsive to residents’ needs, inspired a backlash from tenants and gave hostile politicians the ammunition they needed to systematically privatise public housing.

By outsourcing public services to unaccountable firms seeking higher profit margins at all costs, privatisation paved the way for the Grenfell Tower tragedy, when 72 people lost their lives. Learning from more imaginative and democratic alternatives to this broken system is urgently needed.
