2,012 Food Growing Spaces in London by the end of 2012? Done!

Posted in Movements by Kate Archdeacon on December 27th, 2012

Press Release from Capital Growth:

Capital Growth target

100,000 green-fingered Londoners deliver Mayor’s 2012 food growing target.

The estimated equivalent of 69 Wembley football pitches or 124 acres of disused land in London now brimming with fruit and veg.

The Mayor of London today [Dec 14] announced that the ambitious target to deliver 2012 Capital Growth spaces has been reached, following a four-year scheme to turn disused plots of land into community spaces abundant with fruit and veg. Nearly 100,000 green fingered Londoners have rolled up their sleeves to deliver this leafy Olympic legacy.

The Capital Growth scheme, run by London Food Link, was launched by the Mayor and Rosie Boycott, Chair of London Food, in November 2008. It aimed to create 2,012 growing spaces in London by the end of 2012 with funding from the Mayor and the Big Lottery Fund’s Local Food programme.

The idea is to bring local neighbourhoods and communities together while giving Londoners a chance to grow their own food and green their local area. It is also a response to growing allotment waiting lists, particularly in inner London boroughs, which can be decades long. Capital Growth has worked with landowners and local groups to help identify land for growing and then help people get started in creating successful gardens by providing training and tools.

There are now Capital Growth spaces in every London borough. Food gardens signed up to the scheme have flourished in an extraordinarily diverse and creative range of places, covering an estimated 124 acres of previously disused land. Capital Growth spaces are now growing on roofs, in donated recycling boxes, in skips, alongside canals and in builders’ bags providing healthy food to a range of places including shops and restaurants. The spaces have supported skills and enterprise training, market gardening initiatives and even the development of 50 community bee hives.

Some of the Capital Growth spaces have now scaled up into social enterprises selling produce into cafes, restaurants and market stalls and providing jobs for local people. Other projects that the campaign has supported include larger farms, such as Organic Lea in Waltham Forest that employs 13 full and part time staff doing market gardening under glass houses leased from the local authority. The biggest response to the Capital Growth challenge has come from schools with 687 schools signed up involving 66,000 pupils.

The 2012th space was today announced by the Mayor as St Charles Centre for health and wellbeing in North Kensington. The project, based in a disused courtyard of a hospital, will engage a range of community groups, including youth groups and Age UK, as well as hospital staff to grow their own healthier food.

Open-Source Modular Design Systems

From “How to make everything ourselves: Open modular hardware” by Kris de Decker:

Reverting to traditional handicrafts is one way to sabotage the throwaway society. In this article, we discuss another possibility: the design of modular consumer products, whose parts and components could be re-used for the design of other products.

Initiatives like OpenStructures, Grid Beam, and Contraptor combine the modularity of systems like LEGO, Meccano and Erector with the collaborative power of digital success stories like Wikipedia, Linux or WordPress. An economy based on the concept of re-use would not only bring important advantages in terms of sustainability, but would also save consumers money, speed up innovation, and take manufacturing out of the hands of multinationals. A modular system unites the advantages of standardisation (as parts can be produced cheaply in large amounts) with the advantages of customisation (since a large diversity of unique objects can be made with relatively few parts). Modularity can be found to a greater or lesser extent in many products (like bicycles and computers) and systems (like trains and logistics), but the best examples of modular systems are toys: LEGO, Meccano, and Erector (which is now the brand name of Meccano in the US).

[…]

In spite of the similarities, there is one fundamental difference between modular construction systems such as OpenStructures, Grid Beam and Contraptor, and modular toys such as LEGO, Meccano and Erector. The first group consists of “open” modular systems, where everyone is free to design and produce parts, while the second consists of “closed” modular systems, where all parts are designed and produced by one manufacturer. Closed modular systems produce uniform parts. For instance, all LEGO building blocks are made of plastic. LEGO does not produce building blocks made of wood, aluminium, glass or ceramics. There is a limited range of colours. And because LEGO is a closed system, nobody else is allowed to produce LEGO pieces.

[…]

An open modular system has many advantages over a closed modular system. Since anyone can design parts in an open system, it generates a much larger diversity of parts: they can be made in different colours and materials, and none of the producers can set a fixed price for all consumers. And because many designers constantly review, adapt and improve each others’ work, innovation is accelerated. All open software systems described above are arguably better than their closed counterparts, and some of them have become more successful. A closed modular system only has one advantage: the one who holds the copyright makes a lot of money.

[…]

Open modular construction does not mean that everyone should make their own consumer products. An object like a coffee maker or a workbench could be obtained in at least three ways. Firstly, the consumer can download the digital design and then assemble the object with parts that he or she buys, re-uses, or makes using a 3D-printer or laser cutter, whether at home or at a fab lab or tech shop. It can also happen in a more low-tech fashion, as is the case with Grid Beam: the consumer buys wood or metal beams, and drills the holes himself.

A second option is that a company buys the license of the design (if it is not free) and converts it into a building kit, comparable to a kit from LEGO, Meccano or Erector. In this case, the consumer would not have to search for the parts himself, but he still assembles the product himself, just like he would assemble a piece of furniture by IKEA. Similarly, a company could offer a more general building kit, which can be used to make whatever one would like, similar to a box of basic LEGO bricks. Bit Beam, Contraptor, Open Beam, Maker Beam and, recently, Grid Beam offer one or both of these options.

The third possibility is that a manufacturer places the object on the market as a finished, assembled product. The coffee maker or the workbench would then be sold and bought just as any other product today, but it can be disassembled after use, and its parts can be re-used for other objects.

Seed Matters: Sowing more good

Posted in Movements by Jessica Bird on December 12th, 2012


Screenshot from the Seed Matters website.

An initiative of the Cliff Bar Family Foundation, Seed Matters is dedicated to protecting and ameliorating organic seed, thus increasing the abundance of healthy, nutritious crops that benefit both people and the planet. Their goals are to ‘conserve crop genetic diversity, promote farmers’ roles and rights as seed innovators and stewards, and reinvigorate public seed research and education.’ The Seed Matters website tells the story of seed, about the programs aimed at achieving their goals, and how you can get involved. Oh, and the website is really quite beautiful. – [JB]

From ‘Why Seed Matters: We reap what we sow‘ on the Seed Matters site:

We probably don’t think about it when we sit down to eat our cereal in the morning or tuck the kids into cotton sheets at night, but it all starts with seed.  Seed matters. And the seed we sow affects the quality, nutrition, cost and environmental impact of all the food we eat and every fiber we wear.

It’s time we sow more good. The last several decades of industrial agriculture have developed seed that is suited to intensive chemical agriculture. While this has sometimes resulted in higher yields, it has come with very real costs. Unintended consequences include air and water pollution, increased pesticide use, greater dependence on fossil fuels, degraded soil health, and the loss of biological and genetic diversity. These are facts.

The success of diverse, regional, and resilient food systems requires a different approach to seed – an organic approach.

And yet, today’s farmers don’t have access to sufficient seed developed for organic systems. Worldwide, 95% of organic farmers rely on seed bred for conventional, high-input chemical agriculture. There’s an alternative. Organic plant breeding can increase yields, improve nutrition, and reduce usage of pesticides, fertilizer, and energy. We invite you to join us – engage and grow the work of improving organic seed systems.

Alternative currency creating positive change: Volos, Greece

From the article ‘Greek Town Taps Bartering for a More Shareable City‘ by Kelly McCartney

As Greece continues to search for solutions to its national economic crisis, the port town of Volos has adopted an old-school barter system to help its citizens muddle through. Five years into their recession with 21 percent unemployment, some Volos residents who were short on Euros but long on other resources created a local currency (called TEMs in Greek) that is traded based on non-monetary contributions into the online system. People sign up for a TEMs network account, see what services they might offer to other folks in their area who are in need, and start amassing credits that can be cashed in for things they themselves need. TEMs can be used for everything from bakers to babysitters, teachers to technicians. In theory, the value of one TEM is equal to the value of one Euro.

One participant, acupuncturist Bernhardt Koppold, explained, “It’s an easier, more direct way of exchanging goods and services. “It’s also a way of showing practical solidarity — of building relationships.” Maria Choupis, co-founder of the TEMs network, echoed that sentiment regarding the local alternative currency systems: “They are as much social structures as economic ones. They foster intimacy and mutual support.” Speaking to NPR, Volos Mayor Panos Skotiniotis encouraged municipal governments around the world to consider similar programs of their own to fill in where government and the traditional market are failing to adequately serve citizens: “This is a substitution for the welfare state, and that is why this municipality is encouraging it and wants it to grow.” For its part, though, the Greek Parliament is also very supportive, passing legislation to encourage various non-traditional forms of “entrepreneurship and local development.” Thankfully, other governments are listening. Many more Germans have jumped into alternative currency systems since the Euro was launched. More than two dozen systems now exist there. […] The United States, too, has a number of toes in the alternative currency water […]

Back in Greece, the TEMs system is but one of more than a dozen like it around the country. And, as the new thinking and new currencies take root, more opportunities grow. In Volos, daily markets allow people to barter and trade to their heart’s content. Choupis noted, “They’re quite joyous occasions. It’s very liberating, not using money.” By not being limited by price tags, almost anything is possible. Choupis relayed the story of a woman who arrived at a market with three trays of cakes she had made. The woman’s asking price was only one unit per cake, which Choupis questioned: “I asked her: ‘Do you think that’s enough? After all, you had the cost of the ingredients, the electricity to cook …’ “She replied: ‘Wait until the market is over’, and at the end she had three different kinds of fruit, two one-litre bottles of olive oil, soaps, beans, a dozen eggs and a whole lot of yoghurt. ‘If I had bought all this at the supermarket,’ she said, ‘it would have cost me a great deal more than what it cost to make these cakes.’”

No matter the city, keeping resources and economic systems close to home has both a trickle-down and a ripple-out effect. As more and more local governments open their minds and laws to what alternative currencies and sharing economies have to offer, the more resilient, self-sufficient, and sustainable their populations will become.

Seawater Agriculture: High-tech and Low-tech paths

Image from Seawater Greenhouse

In the Guardian this week, there’s an article by Jonathan Margolis about the commercialisation of a technology that uses seawater as the main element of agriculturally productive greenhouses.  Much of the article focuses on the way the technology, developed by British theatre lighting engineer Charlie Paton, has been scaled up and combined with extra technology to provide consistent, commercial-quality crops from the Sundrop Farms greenhouse in the desert outside Port Augusta, in South Australia.  On it’s own, that’s pretty exciting and well worth a read.

A 75m line of motorised parabolic mirrors that follow the sun all day focuses its heat on a pipe containing a sealed-in supply of oil. The hot oil in turn heats nearby tanks of seawater pumped up from a few metres below ground – the shore is only 100m away. The oil brings the seawater up to 160C and steam from this drives turbines providing electricity. Some of the hot water from the process heats the greenhouse through the cold desert nights, while the rest is fed into a desalination plant that produces the 10,000 litres of fresh water a day needed to keep the plants happy. The water the grower gets is pure and ready for the perfect mix of nutrients to be added. The air in the greenhouse is kept humid and cool by trickling water over a wall of honeycombed cardboard evaporative pads through which air is driven by wind and fans. The system is hi-tech all the way; the greenhouse is in a remote spot, but the grower, a hyper-enthusiastic 27-year-old Canadian, Dave Pratt, can rather delightfully control all the growing conditions for his tonnes of crops from an iPhone app if he’s out on the town – or even home in Ontario.

The remainder of the article touches on the divergence of philosophy between Paton’s Seawater Greenhouse, and SunDrop.

The Seawater Greenhouse method, which they are still promoting actively, involves no desalination plant, no gleaming solar mirrors and little by way of anything electronic. Everything in the Seawater Greenhouse vision is low-tech, cheap to start up and reliant on the subtle, gentle interaction of evaporation and condensation of seawater with wind, both natural and artificial, blown by fans powered by solar panels. If things go wrong and production is disrupted by a glitch in this model, you just persuade people to eat perfectly good but odd-looking produce – or harvest less and stand firm by your sustainable principles.

For those of us interested in the gap between local, low-tech production designed to shift society away from BAU, and the changes that occur when those systems scale up to cater to the existing market, this article may also provide a few points of contention.
