What happened to the rainforest?

Jacob Andrén, an ordinary Swedish school kid in the 1980′s, was one of all the millions of children globally who gathered up with his class mates and collected money to “save the rainforest”. Many of us did it, selling home made cookies or walking the streets of our cities with money collecting boxes. The money was transfered, a certificate arrived and decorated lots of classrooms as a memory of the deeds. But what actually happened to the forest?

20 years later, Jacob starts asking himself these questions and ends up going to Costa Rica to find out for himself. In the film “I bought a rainforest” we can follow him on his journey through lush jungle and devastated forests (watch a trailer for the film here).

Rainforest covers about 7 percent of the worlds’s surface, but is home to about half of the worlds’ species. It is also an enormous storage space for coal, which would lead to unbelievable amounts of greenhouse gases being dispersed into the atmosphere if it was cut down or burnt.

To make sure this doesn’t happen action is of course needed on many levels of society, from governments making laws, international reductions of emissions that in the long run affect the rainforest or the way rainforest timber is allowed to be used. But if school children all over the world feel that they can do something about it – and if it actually saves the forest – that probably contributes to a lot more than just stopping the chain saws.

Here you can watch several short films about the different threats against the rainforest and why the forest is so important to the whole planet.

More resilient cities

Urban-Planet-Atlas

Ideas for a Shanghai beyond oil in the Urban Planet Atlas

The sustainability discussion is often filled with difficult terms. Most of them can be avoided, but one that I actually find useful is the term resilience.

Resilience, in a simplified sense, can be said to be the elasticity of for example a society or an ecosystem. More exactly it refers to “the capacity of a social-ecological system both to withstand perturbations from for instance climate or economic shocks and to rebuild and renew itself afterwards”. Yet anoother way to describe it: As we cannot prevent all types of shocks, we have to be able to cope with them.

Today resilience could often be better. One example of that is how the effects of hurricane Katrina were much more severe because of a weakened wetland that couldn’t absorb the big waves. Another example is, as I mentioned in my last blog post, how vulnerable cities are if incoming food transports would stop for one reason or another.

One of the places where resilience is specifically studied is at the Stockholm Resilience Centre. This centre has now developed an online platform for sustainable urban development, which will be launched at the Expo2010 in Shanghai.

The idea is to point out the close connections between social and natural systems, and the fundamental role ecosystem services play for human wellbeing.

An upgraded version of the Urban Planet Atlas, as they call it, will be launched in Shanghai in October, but it is already possible to try it online. Shanghai itself is one of the example cities which are already put into the atlas. Check under “Solutions for Sustainable and Resilient Cities” and see how students at the Royal University College of Fine Arts in Stockholm has envisioned a Shanghai beyond oil.

B(l)ooming interest for urban foodgrowing

In Sweden the sales of vegetable seeds have now outstripped those for flowers by a considerable margin and magazines are full of advice on how to set up your own plantation. In urban areas waiting lists for allotments are bursting with names of people who can’t wait to put their hands in the soil.

Apart from being fun, I think there are several reasons for this reawakened interest.
Cities are proud beings, not looking to others for help, yet so totally helpless without the surrounding world providing them with food and energy. When I last year interviewed Rosie Boycott, who is appointed by London’s mayor as head of the London Food Board, she told me London has a food stock enough for three days’ consumption. I suspect the situation is similar in most cities allover the world. We are enormously dependant on transports for our food to reach us.

Many have also started to think about how dependant food production is on cheap energy, especially oil, for running tractors, making fertilizers, pesticides and so on. That, together with the fact that oil reserves won’t last forever (what is also known as Peak Oil) leads to the conclusion that more of our food has to be produced closer to where it is consumed, in less energy-demanding ways. And how could anything be more local than homegrown vegetables?

After wanting to grow things but not having come to the action part of it, I have finally realised that growing together with others is by far the best and most enjoyable way to do it. Recently I started in a study circle with other interested at a local garden assoication which has kindly let us a piece of their land. Measuring, digging and weeding is something entirely different if you can chat to nice people while doing it. And it all goes so much faster.

The actual planting will have to wait though, but in the meantime I have started growing squash, tomato and parsley in my windowsill and will let you follow the progress of my gardening attempts this summer.

Making city life more sustainable

One of the big challenges on the bumpy road towards a more sustainable world are the cities. Today about 80 percent of global CO2 emissions come from cities (in Sweden 60 percent). With more and more people moving into urban areas – according to UN about 70 percent of the World’s population will be city dwellers by year 2050 – cities will have to change in many ways if they are to be both environmentally and socially sustainable.

This issue occupies a lot of brains all over the world, resulting in some interesting projects that can work as pieces in this immense puzzle. One of them is Kungsbrohuset, an office building next to the central station of Stockholm, which will be inaugurated this week. It tries to gather most of the existing knowledge of how to make a building more environmentally conscious.
For example the excess body heat of the 200 000 travellers rushing through the adjacent Central Station of Stockholm will be used to at least partially heat Kungsbrohuset. Energy efficient windows allow the daylight to enter, lowering energy use for lighting, but shuts the summer heat out. Fiber optics are used to lead sunlight into darker areas of the house.

But constructing a more sustainable building doesn’t only mean using the latest technology. Another important thing is making it easier for people to make better choices. One way is offering those working in the building access to safe parking spaces for their bicycles, the possibility to take a shower and also facilities to repair their bikes.

After having fixed a punctured bike tire on my own office floor a few weeks ago, I know I would appreciate a repair shop like that a lot…
