My politics of ecology and justice

Following my previous blog post about the Young Greens and lots of discussion with friends and fellow party members, I want to set out clearly why ecology defines my philosophical basis rather than social and environmental justice.

To avoid misunderstandings from the outset, I think social and environmental justice are important, but they don’t define my political philosophy.

The new philosophical basis of the Green Party says:

A system based on inequality and exploitation is threatening the future of the planet on which we depend, and encouraging reckless and environmentally damaging consumerism…. The Green Party is a party of social and environmental justice, which supports a radical transformation of society for the benefit of all, and for the planet as a whole.

This sounds great! What could be wrong with that? I hope I might persuade you why I don’t think it is quite right, or at least encourage more thought and debate about political philosophy and the precise meaning of different terms. Continue reading

Young Greens for the environment

I joked a couple of days ago that I should set-up a Young Greens for the Environment grouping in the Green Party. I wasn’t being facetious, because I think there is a lack of environmentalism (or perhaps even a current of anti-environment thought) within the Young Greens (the organisation, distinct from the many Greens who are under 30).

By all reports, Young Greens were out in force at this weekend’s party conference, along with older members who have joined in recent years in search of a left-of-Labour party with realistic electoral prospects. Their scalp was a change to the party’s philosophical basis, removing clauses like this:

Life on Earth is under immense pressure. It is human activity, more than anything else, which is threatening the well-being of the environment on which we depend. Conventional politics has failed us because its values are fundamentally flawed.

And replacing them with clauses like this:

A system based on inequality and exploitation is threatening the future of the planet on which we depend, and encouraging reckless and environmentally damaging consumerism.

Leaving side various quibbles, the new clauses contain sentiments I broadly agree with. Green politics has, for a long time, had four basic principles: ecology, social justice, peace and democracy, all equally important goals.

What’s interesting is that the preamble to this policy motion went further than saying social justice is as important as ecology. It sought to “make social justice central“, asking that we “put our struggle for equality and democratic control of resources at the centre” of our politics (my emphasis).

Keeping the environment central

I am dismayed by this change.

I joined the Green Party because I think the environmental crises we are creating are the single biggest political problem we face. I want to distinguish between goals – the world we want to see – and struggles – the issues or problems we need to tackle. I think social justice, peace and democracy are equally important goals, but the raison d’être of the Green Party is surely that no other political party in England and Wales takes the struggle for the environment seriously?

If we don’t fix our environmental problems, the other concerns might as well not matter. Social justice issues like welfare reform will pale into insignificance as runaway climate change, the exhaustion of oceans and soils, the disruption of the nitrogen cycle and other growing crises all take their toll. Unlike most social justice issues, environmental crises are stuck in feedback loops that mean late or timid action fatally undermines our ability to tackle them later on; you can always build more homes in 2015 to make good on a few years of inaction, but we can’t, yet, take greenhouse gases out of the atmosphere at a scale that could undo the damage of past years.

It is possible to conceive of an environmentally sound society that is socially unjust (such as many poor countries today) and of socially just societies that are environmentally unsound (such as many Latin American lefty countries, though they are of course undermining the foundations of their future prosperity). We are in politics to bring about a society that is environmentally sound, socially just, democratic and peaceful. But of all the struggles we face to achieve those goals, we must, I believe, give the environmental problems the highest priority because we live in a country in which they are the most severely neglected, and in which they pose by far the greatest threat.

One slogan I use with confidence is, “if there isn’t a Green in the room it won’t get discussed”. On occasion this is true of pay inequality, co-operative housing and alternatives to military intervention. But it is most often, and most starkly, true of environmental issues. We can and should work across a broad range of topics, but if we fail to work on environmental topics as a central concern then nobody will work on them in a serious way.

I also feel slightly queasy at the implication that the party is moving away from a deep green, ecological philosophy. The pale Green approach asks us to fix problems like pollution and resource depletion in order to build a socially just, peaceful and democratic society; the environment is important insofar as it underpins those things we really value. The deep Green approach asks that we adopt a wholly different framework, an ecological framework that sees humanity as part of nature and all of nature as inherently valuable. We struggle against pollution and resource depletion and other problems in order to realise a world with greater ecological well-being. Our understanding of social justice, democracy and peace flows from our ecological philosophy, which is central and formative. You can read more about this “ecological philosophy” here.

When we discuss policies that can be pursued by Green councillors, people without the power to overturn the basic values of the UK political system, we must be more pragmatic. For example, I don’t think it’s right to fight against housing development in regions of the UK that have severe shortages, on the grounds that we might – if in national government – begin to rebalance the UK’s economy to other regions with more empty homes and less housing stress (something I wrote about here).

But when we discuss our philosophical basis, we needn’t make this compromise.

To my mind, this new philosophical basis throws that out, and makes us a left wing party concerned with humankind that is fixing environmental problems for humankind’s benefit.

The Young Green element, or bloc

The motion vote came about in part through the emergence of something of a ‘bloc’ of Young Greens, self-identified as more left-wing, less hippyish and less deep Green than previous generations.

This first really came to my attention in a Guardian interview with Adam Ramsay[update: I should point out Adam isn't an officer or spokesperson for the Young Greens, I mention him as a prominent 'young' Green who talks up this idea of a new approach among younger members] Here is the full quote:

There are, he explains, three elements within British green politics: the kind of veteran “ecologist liberals” represented by the Greens’ London mayoral candidate Jenny Jones; more left-leaning people who joined the party towards the end of the 1980s, like their current leader Caroline Lucas; and Ramsay’s own lot: what he calls “the Iraq war generation, which blurs into the cuts generation: people who are students now”. The middle group, he says, tends to side with his faction, and the result is an increasing emphasis on such issues as inequality and the public/private balance, as well as the Green staples of sustainability and climate change. “There’s more of us now, so we win,” he says. “And in terms of ideas and energy – we run the party.”

I know Adam from our shared time as activists in People & Planet, a fantastic student campaigning organisation he now works for. I admire Adam’s energy for direct action politics, and respect his tireless work to further Green politics. Back in the day, when I was on People & Planet’s Management Committee (a kind of democratic board) we were both pushing for the organisation to campaign on workers’ rights and to take a harder, more political stance following years of slightly fuzzy trade justice work. But his interview made me think we have subsequently departed for different planets.

My first bone to pick was his description of Jenny Jones as an “ecologist liberal”, and by implication not a lefty who would pursue issues like inequality and privatisation. That is rubbish, but not a tangent I have space for here.

My second bone was the idea that there are delimited “elements” in the party. What made it even worse was that Adam was apparently suggesting some elements have taken control of the party!

I’m not in any element or faction, thank you. I’m a Green, I follow my values and the evidence to support any proposal that I think is right. Talk of factions encourages people to switch off their brains and vote en bloc, and even to start imagining that there are other factions they should oppose or undermine. This divisive attitude put me off Green Left, despite feeling I was on the left of the party when it launched.

At conferences I have voted to remove unscientific nonsense about homeopathy that was a relic of a new age form of deep Green thinking, and I have voted to strengthen private tenants’ rights in the face of concerns from older home-owning and landlord members, but I don’t identify with young or old exclusively. I would have voted against this motion.

The emergence of the pale Green bloc

Back to Adam’s quote.

Like him, I came to the Green Party following nine years of Labour’s work to wage foreign wars, privatise public services and maintain the global trade agreements that kept corporations in the business of exploiting people and planet. I came to the Greens out of admiration for our Living Wage policy, but also for our deep commitment to ecology and the recognition that pitting the environment against the economy or society is always a false choice, always an ignorance of environmental science and economics, always a mistake, and deeply out of kilter with my philosophy. I joined following years campaigning on climate change, trade justice and the Afghanistan and Iraq wars, and my early years coincided with the buildup to the Copenhagen conference, during which climate change was unambiguously one of the biggest campaigning issues of the day.

I can see that people five or ten years younger than me have had a different track record. I first noticed this when drawing up our manifesto for the London Mayoral and Assembly elections in May 2012. I had extended various invitations to the London Young Greens committee to meet and discuss what they would like to see, to host workshops with new young  members, and to consider whether we should write a youth section into the manifesto. My offer wasn’t taken up, and in good time I received a polished Young Green manifesto to consider. The document had lots of good ideas, but there was nothing – and I mean, nothing – about the environment. From the Young Greens!

I was pretty astonished, until I reflected on the main issues on campuses in the preceding years – student fees, cuts, anti-austerity, pay inequality. Like weather vanes, the Young Green committee in London had followed the political winds and dropped any interest in the single biggest intergenerational injustice we have to deal with – climate change – let alone other environmental issues affecting young people or the pressures on London’s environment.

This has been repeated with the national Young Green’s innovation of  their own policy platforms. The first two concern housing and economic democracy (see Google cache while their site is down). These contain lots of  great ideas, but again the environment is almost entirely absent. The one mention of environmental issues in in relation to housing and energy use, left as a single pale Green consideration, far from the deep Green heritage of the party.

Do we need Young Greens for the Environment?

I don’t really want to propose setting up another faction, a group-within-a-group. That would only add to the problems we face.

I’d prefer to believe that we are really all on the same page, and that we can find ways to bring ecology back to the fore in the coming years.

I would like to think there are fellow Greens aged 30 and under who still think that ecology is a central concern; who think that it is, of all our core values, the one we most urgently need to struggle for given that it is the only one comprehensively ignored by the other four national parties; and who are also concerned at these signs that their peers seem to be downgrading ecology, either deliberately or by omission. Fellow Greens who recognise the need at times to present ecology in terms of social justice, and to give social justice and democracy greater prominence in our day to day work, but who still feel that ecology is paramount.

Join me! Or tell me what I’m missing…

Analysing Southwark’s natural geography

Following my map of London’s green and blue infrastructure, I have been working on some analysis of the land uses.

I was inspired and encouraged to try this by Liliana’s interesting work called “imagining all of Southwark“. Lili and Ari have managed to get the council to release lots of data on properties and car parking, and they are producing analysis of this data by postal code area and by street. They haven’t managed to get anything on land uses, so I thought, why not produce this with OpenStreetMap data?

A few evenings later, here is the result shared on Google docs (direct link) covering the eight postal code areas that between them cover most of the borough (SE1, SE5, SE15, SE16, SE17, SE21, SE22, SE24):

What the data means

The “summary” worksheet shows the total land area, expressed in hectares (10,000 m2), for various different types of land coverage. I have also calculated the percentage of that postal code area that the land uses represent, which gives an interesting insight into the differences between the areas.

Some of the land uses will overlap, for example miscellaneous bits of green space are often mapped on top of residential areas. So the numbers aren’t supposed to add up to anything like 100%.

The spreadsheet also contains worksheets for each postal code area. These contain a dump of all the objects in OpenStreetMap in those postal code areas, and this is the raw data the summary spreadsheet uses to get the totals.

Flaws in the data

You should use this data with a large spoonful of salt. Here are the significant flaws I have noticed:

Postal code areas are approximate, for example the boundary between SE15 and SE22 should mark the boundary between Peckham Rye Common (SE15) and Peckham Rye Park (SE22). In my data both the park and the common show up in both of the postal codes, because the boundary isn’t quite right. Read down to my method to see why. The errors introduced are pretty tiny in most places (plus or minus a few meters along the full boundary), and probably cancel themselves out for big land uses like residential, but they probably also introduce some significant errors for parks where the boundaries go awry by 20-30m in places. Sadly there aren’t any accurate open data polygons I can use.

Data is missing because OpenStreetMap contributors haven’t mapped it. Of course the easy solution here is to get more of it mapped and up to date! My estimate of the different types is as follows:

  • Allotments: complete for the whole borough.
  • Parks and commons: all major and district parks complete.
  • Misc green spaces: very poor coverage of, for example, large areas of grass on estates, especially in SE5, the north pat of SE15 and SE17.
  • Woods/forest: all major woods complete, coverage of big clumps of trees e.g. on a housing estate or in a park is very uneven.
  • Residential: complete except for SE16.
  • Industrial, retail, commercial: large areas are complete, but small shopping parades, industrial parks and rows of offices are very patchy.
  • Brownfield/construction: patchy across the borough and sometimes out of date as sites are built on.

Data is also sometimes missing because of flaws in the Geofabrik shapefiles, not all of which I have corrected. For example, I noticed they were missing commons so I manually added those in, but I may have missed other land uses. One major omission, a shame given the interest in them, is the humble sports pitch/playing field.

How I produced this

After a lot of experimentation – I’ve never been trained to use GIS tools – I worked out this method. If you know of an easier way I’d love to hear about it.

  1. Prepare the boundary data:
    1. Extract a polygon for the London Borough of Southwark from the OS Boundary-Line data.
    2. Download the OS Code-Point-Open data, open the spreadsheet for the SE area in QGIS and use the ftools ‘Voronoi polygons’ plugin to infer polygons for the postal codes from the centroids. Post code centroids are very dense in the middle of residential areas, so the boundary between SE15 4HR and SE22 9BD is only going to be out by a few meters, but are quite far apart with large parks and commons, so the inferred boundaries get less accurate in those areas. See this map for an illustration of the Peckham Rye Park / Common problem mentioned above.
    3. Merge together postal codes into the areas (e.g. SE22 9QF, SE22 4DU etc. into SE22) by quering the shapefile for all objects with postal codes starting with SE22, then using the mmqgis merge tool to merge them into single polygons. Clean up the attributes so the shapefile just has one attribute for the correct postal code area.
    4. Clip the postal codes by the Southwark polygon and save the result – finally – as the postal codes shapefile for Southwark.
  2. Prepare the land use data:
    1. Download the  OpenStreetMap shapefiles from Geofabrik for Greater London.
    2. Download common and marsh ways/relations using the Overpass API (with the meta flag on), import the data into QGIS using the OpenStreetMap plugin, and save the data as a Shapefile.
    3. Merge together the Geofabrik natural and landuse shapefiles with my Overpass-derived shapefile into one land use shape file using the mmqgis plugin.
    4. Clip the land use file by the Southwark polygon and save the result – finally – as the land uses shapefile for Southwark.
  3. Produce the postal code stats; for each postal code:
    1. Select the postal code, and clip the land use layer to that selected code, saving it as a new shapefile.
    2. Open that shapefile, then save it in a new projection that will be in meters rather than degrees (I used  EPSG:32631 – WGS 84 / UTM zone 31N).
    3. Open the new shapefile, then run the ftools ‘Export/add geometry columns’ tool (in Vector/Geometry Tools) to add two attributes to the objects for the area and perimeter.
    4. Save the layer again as a CSV file.
  4. Produce the stats for the area of each postal code so we can calculate % of the area as well as ha for each land use:
    1. Save the Southwark postal codes polygon in the meters projection, add the geometry columns, and save as a CSV file.
  5. Collate all the data
    1. Tidy up and copy the data from each CSV file into a spreadsheet, then add in the formulae to tot everything up. You’re done!

For reference, some of the totals in the summary work off more than one land use type so here are the categories and the corresponding OpenStreetMap tags:

  • Allotments – landuse=allotments
  • Parks and commons – leisure=park / leisure=common
  • Misc green spaces – landuse=conservation / landuse=farm / leisure=garden / landuse=grass / landuse=greenfield / landuse=greenspace / landuse=meadow / landuse=orchard / landuse=recreation_ground
  • Woods and forest – landuse=forest / natural=wood
  • Residential, industrial, retail, commercial, brownfield, construction – corresponding landuse tags

Future ideas

One obvious improvement would be to get more data in. Perhaps this first analysis will encourage people to help out with that? I have also emailed Geofabrik about the flaws I have discovered in their shapefiles, so I hope those get fixed.

Another thought is to produce the stats by council ward. But given that there are far more wards, I’d like to find a quicker way of producing the stats for each ward (step three above) first.

It would also be interesting to do it by town/suburb, for example comparing Peckham to East Dulwich. But we don’t have any meaningful boundaries for those natural areas. It would be really interesting to do a mass version of “this isn’t fucking Dalston” for a whole borough, using the Voronoi polygons method to infer areas from surveys at thousands of locations around the borough. One day…

London’s natural geography

I’ve been playing around with open data from OpenStreetMap and Natural England to make a pretty map of “green and blue infrastructure” in London. Here’s the result:

You can download a PDF version suitable for printing here: natural_london.

I’m pretty happy with the result, my first real attempt to produce something useful with QGIS. The data I used was:

There’s no reason the Natural England data couldn’t be manually added to OpenStreetMap, giving us a complete dataset of natural features. I just chose to get on and do it this way rather than wait, or try to add all the data across areas of the city I don’t know well and am not going to visit any time soon. I also didn’t really need to use the Ordnance Survey data for boundaries, but it’s slightly more accurate and complete than OpenStreetMap data.

The map is probably missing lots of smaller patches of green space, including grass verges, green roofs and biodiverse brownfield sites. The biggest omission is the humble private garden. They cover 24% of London’s land!

But the map at least shows the more obvious, visible, public green spaces, and is a nice example of what a geek with no GIS training (but years of playing with OpenStreetMap) can do with free software and free data these days.
