Student-led resilience workshop after Resilience 2008

Realise, Reorganise, Adapt – Reorganising knowledge for sustainability is a student led resilience workshop that follows the Resilience conference on Friday April 18, 10.00-14.00 at Stockholm Resilience Centre.

It will address the questions:

  • How should we organise knowledge for sustainability?
  • Is the adaptive cycle a useful tool for organising interdisciplinary research and building knowledge for sustainability?
  • What lessons can we learn from different programs, their organisation and their various phases – conservation, collapses, and reorganisations?
  • Building on experience from students and their programs, we hope to identify what lessons emerge from these cases.

They hope to build an international student network of resilience researchers.

Visualizing US CO2 emissions

A neat visualization of CO2 emissions from the Vulcan project. They CO2 levels, which aren’t measured, from fine scale air pollution data and atmospheric models to produce high resolution hourly map of US CO2 emissions. Kevin Gurney posted a visualization of their data on YouTube, in which you can see the daily and seasonal variation in emissions.

Climate change amplifies eutrophication

Hans Paerl and Jef Huisman have a perspective article in Science that reviews how climate change may promote blooms of cyanobacteria Blooms Like It Hot (320 (5872): 57 ):

Nutrient overenrichment of waters by urban, agricultural, and industrial development has promoted the growth of cyanobacteria as harmful algal blooms (1, 2). These blooms increase the turbidity of aquatic ecosystems, smothering aquatic plants and thereby suppressing important invertebrate and fish habitats. Die-off of blooms may deplete oxygen, killing fish. Some cyanobacteria produce toxins, which can cause serious and occasionally fatal human liver, digestive, neurological, and skin diseases (1-4). Cyanobacterial blooms thus threaten many aquatic ecosystems, including Lake Victoria in Africa, Lake Erie in North America, Lake Taihu in China, and the Baltic Sea in Europe (3-6). Climate change is a potent catalyst for the further expansion of these blooms.

Rising temperatures favor cyanobacteria in several ways. Cyanobacteria generally grow better at higher temperatures (often above 25°C) than do other phytoplankton species such as diatoms and green algae (7, 8). This gives cyanobacteria a competitive advantage at elevated temperatures (8, 9). Warming of surface waters also strengthens the vertical stratification of lakes, reducing vertical mixing. Furthermore, global warming causes lakes to stratify earlier in spring and destratify later in autumn, which lengthens optimal growth periods. Many cyanobacteria exploit these stratified conditions by forming intracellular gas vesicles, which make the cells buoyant. Buoyant cyanobacteria float upward when mixing is weak and accumulate in dense surface blooms (1, 2, 7) (see the figure). These surface blooms shade underlying nonbuoyant phytoplankton, thus suppressing their opponents through competition for light (8). Cyanobacterial blooms may even locally increase water temperatures through the intense absorption of light. The temperatures of surface blooms in the Baltic Sea and in Lake IJsselmeer, Netherlands, can be at least 1.5°C above those of ambient waters (10, 11). This positive feedback provides additional competitive dominance of buoyant cyanobacteria over nonbuoyant phytoplankton.

Global warming also affects patterns of precipitation and drought. These changes in the hydrological cycle could further enhance cyanobacterial dominance. For example, more intense precipitation will increase surface and groundwater nutrient discharge into water bodies. In the short term, freshwater discharge may prevent blooms by flushing. However, as the discharge subsides and water residence time increases as a result of drought, nutrient loads will be captured, eventually promoting blooms. This scenario takes place when elevated winter-spring rainfall and flushing events are followed by protracted periods of summer drought. This sequence of events has triggered massive algal blooms in aquatic ecosystems serving critical drinking water, fishery, and recreational needs. Attempts to control fluctuations in the discharge of rivers and lakes by means of dams and sluices may increase residence time, further aggravating cyanobacteria-related ecological and human health problems.

Changing Matters – the Resilience Art Exhibition

In a few weeks the conference Resilience 2008 will begin in Stockholm. Along the the scientific talks is an art exhibit on resilience. Its called Changing Matters – the Resilience Art Exhibition and will be opening at the Naturhistoriska riksmuseet just before the conference (it runs 12 April -7 September 2008).

On the conference website the art exhibit and its rationale are described.

A central message of the Resilience 2008 Conference is that resilience is not just an ecological issue, or a social, economic or cultural issue. These issues are interlinked. Resilience involves ecological, economic, cultural, ethical and other social dimensions and values. Sustaining and developing social capacity will be a prerequisite for adaptability and transformability.

To explore this fundamentally important feature, and to complement and enhance the scientific symposium, we invited artists to submit proposals for a Resilience Art Exhibition to be held in connection with the science and policy conference. The full Resilience Art Exhibition, where invited artists interpret the notion of resilience, will take place between April 12 and September 7, 2008, at The Swedish Museum of Natural History (Naturhistoriska riksmuseet).

During the conference there will also be highlights and excerpts shown in the grand lecture hall Aula Magna at Stockholm University.

Colours of Salt Pond Ecosystems

The South San Francisco Bay salt evaporation ponds, which are often visible from planes flying in and out of San Francisco Airport. Salt ponds with different salinity levels are inhabited by different organisms that give them different colours. Algae colour low salinity ponds green, while different algae color high salinity ponds red. Bacteria and shrimp also shift the colours.

Hidden Ecologies is blog describes work from the San Francisco Exploratorium that explores and visualizes the transitional landscapes surounding San Francisco Bay at different scales. Architect Cris Benton has made a collage of his photos from high and low elevations of Salt Pond Colors:

Revenge of the Slow

cambray cheese platterBruce Sterling writes about the networked boutique localism of the slow food movement in a Metropolis magazine article Revenge of the Slow:

Slow Food began as a jolly clique of leftist academics, entertainers, wine snobs, and pop stars, all friends of Ital­ian journalist and radio personality Carlo Petrini. Their galvanizing moment, which occurred in 1986, was an anti-McDonald’s demonstration at which Petrini and his dining buddies brandished pasta pans while folk-dancing in the streets of Rome. This prescient intervention predated Jose Bove’s violent wrecking of a French McDonald’s by some 13 years. While the anti-WTO crowd was politically harassing corporate globalizers, Slow Food was methodically building constructive alternatives. Today, Slow Food is well-nigh as “glo­­bal” as McDonald’s but networked rather than hierarchical. Year by methodical year the Slow Food network has stuck its fingers into a host of pies.

As a nonprofit heritage organization, the Slow Food empire retains a mere 150 full-time employees with a modest budget of $37 million a year. Yet Slow Food has invented the modern Italian food-heritage industry. Today it is a thriving ganglion of local chapters, called convivia, which number about 83,000 people in more than 100 countries. It’s also a publishing house specializing in tourist guidebooks, restaurant recipes, and heritage reprints. …

The cleverest innovation to date is the network’s presidium system. The Slow Food “presidia” make up a grassroots bottom-up version of the European “Domain of Control” system, which requires, for instance, that true “champagnes” must come from the province of Champagne, while lesser fizzy brews are labeled mere “sparkling wines.” These presidia have made Slow Food the planetary paladin of local production. Slow Food deploys its convivia to serve as talent scouts for food rarities (such as Polish Mead, the Istrian Giant Ox, and the Tehuacan Amaranth). Candidate discoveries are passed to Slow Food’s International Ark Commission, which decides whether the foodstuff is worthy of inclusion. Its criteria are strict:

(a) Is the product nonglobalized or, better yet, inherently nonglobalizable?

(b) Is it artisanally made (so there’s no possibility of any industrial economies of scale)?

(c) Is it high-quality (the consumer “wow” factor)?

(d) Is it sustainably produced? (Not only is this politically pleasing, but it swiftly eliminates competition from most multinationals.)

(e) Is this product likely to disappear from the planet otherwise? (Biodiversity must be served!)

For the foodstuff artisan (commonly dirt poor and neglected somewhere in the planet’s backwoods), Slow Food has a strong value proposal. It is, among its many other roles, a potent promotion machine. Transforming local rarities into fodder for global gourmets is, of course, profitable. And although he’s no capitalist—the much honored Petrini is more justly described as a major cultural figure—he was among the first to realize that as an economic system globalization destroys certain valuable goods and services that rich people very much want to buy. In a globalized “flat world,” the remaining peaks soar in value and become natural clusters for a planetary elite. …

A local product with irreducible rarity can be sold to a small elite around the world. But it can’t be sold to mass consumers because it doesn’t scale up in volume, so it can never lose its cachet. The trick is in uniting these niches. A capitalist business has a hard time of that, but a cultural network is a different story. …

Slow Food, in its solemn wisdom, will methodically seek out local producers of the product, raise their consciousness, and then fly them to Italy and unite them in subsidized conferences. The group links local farmers, bakers, millers, and butchers with their peers in other countries: the “Terra Madre” global network. Having built this distribution net, Slow Food offers grants to needy producers for things like barns, butcher shops, and tractors. Then as a final twist, Slow Foodies cheerily eat the end products themselves.

The upshot is an obscure piece of rural heritage cunningly reengineered as a curated service/­product in Europe’s modern food-heritage industry. To Americans it might seem paradoxical that Eur­ope’s rural farmers could be at once blood-and-soil heritage patriots and culture-industry jet-setters whose star clients are wealthy politicized food theorists. But while McDonald’s mechanically peddles burgers to the poor, Slow Food acculturates the planet’s wealthy to the gourmand quality of life long cherished by the European bon vivant. They have about as much in common as an aging shark and a networked swarm of piranhas.

What Will Life Be Like in the Year 2008?

What Will Life Be Like in the Year 2008? from November, 1968 issue of Mechanix Illustrated, describes life in 2008:

It’S 8 a.m., Tuesday, Nov. 18, 2008, and you are headed for a business appointment 300 mi. away. You slide into your sleek, two-passenger air-cushion car, press a sequence of buttons and the national traffic computer notes your destination, figures out the current traffic situation and signals your car to slide out of the garage. Hands free, you sit back and begin to read the morning paper—which is flashed on a flat TV screen over the car’s dashboard. Tapping a button changes the page.

The car accelerates to 150 mph in the city’s suburbs, then hits 250 mph in less built-up areas, gliding over the smooth plastic road. You whizz past a string of cities, many of them covered by the new domes that keep them evenly climatized year round. Traffic is heavy, typically, but there’s no need to worry. The traffic computer, which feeds and receives signals to and from all cars in transit between cities, keeps vehicles at least 50 yds. apart. There hasn’t been an accident since the system was inaugurated. Suddenly your TV phone buzzes. A business associate wants a sketch of a new kind of impeller your firm is putting out for sports boats. You reach for your attache case and draw the diagram with a pencil-thin infrared flashlight on what looks like a TV screen lining the back of the case. The diagram is relayed to a similar screen in your associate’s office, 200 mi. away. He jabs a button and a fixed copy of the sketch rolls out of the device. He wishes you good luck at the coming meeting and signs off. ….

The article interested not just for its successes and failures of prediction, but what aspects of the world were thought to be worth discussing.

Global Glacier Decline

The World Glacier Monitoring Service‘s latest report shows that, based on data from 30 glaciers spread in nine mountainous regions of the world, glacier mass balance is negative (i.e. glacier melt exceeds ice formation) and the average mass balance is declining (i.e. more ice is melting each year).

Glacier Mass Loss

Figure 1a and 1b: Mean cumulative specific net balance (top) and mean annual specific net balance (bottom) from continuously measured on 30 glaciers in 9 mountain ranges for the period 1980-2004, on 29 glaciers in 9 mountain ranges for 2005, and on 27 glaciers in 8 mountain ranges for 2006. (see World Glacier Monitoring Service).

Andy Revkin comments on the report in Farewell to Ice on his weblog, and the USA’s National Snow and Ice Data Center host a collection of repeat photography of glaciers documenting their decline.
