Stockholm Whiteboard Seminars

Fredrik Moberg from Albaeco and Stockholm Resilience Centre has developed a new video seminar concept with Sturle Simonsen called the “Stockholm Whiteboard Seminars”. He says:

The idea is to get away from seminars loaded with lengthy and flashy PowerPoints and go back to basics. So, take the opportunity to get a short and close encounter with a top scientist in the field of sustainable development, who uses the whiteboard to explain an important concept or recent research insight just for you! So, what is this Whiteboard Seminar concept all about? The criteria we use are:

• The scientist has a maximum of 7 minutes to present
• The presentation must be done in an as easy, clear and convincing way possible
• It should be related to people’s everyday life or a current topic in media/politics
• The presentation should evolve around a simple model or a drawing
• The presenter is only allowed to use a black whiteboard pen

The first two videos in the series are below the break…

Community-mapping projects for sustainability

How to strengthen the voice and knowledge of locals in planning processes? Many have argued that in order to face complexity and uncertainty, decision-making processes need to engage with a diverse set of actors representing different knowledges (see for instance recent article by Carpenter, Folke, Scheffer and Westley 2009, or from planning theory, Jonathan Murdoch, Post-structuralist Geography, 2006).

green-map

One civil-society response seems to be to engage with an activity historically mostly attached to top-down and centralized control, and start producing your own maps! By merging community activism with cheap Internet mapping techniques, such local responses are growing into an emergent international movement of community map-makers at Green Map ®.

The organization writes that the focus is to “highlight the social, cultural, and sustainable resources of a particular geographic area” and to support “perspective-changing community ‘portraits’ which act as comprehensive inventories for decision-making and as practical guides for residents and tourists.”

stockholm-green-map-betaversion

Starting in New York in 1992 the organization now claims to collect hundreds of evolving maps across the world. Just recently the initiative reached one of the community organizations here in my own neigbourhood Bagarmossen, Stockholm, to build the “Stockholm Green Map” (betaversion).

Of course maps have historically been seen as a tool for control, representing the vision of the ruler or the state. And although a critical analysis is still valid when it comes to community-maps, the Green Map ® project and similar projects certainly bring out new possibilities for the general public to participate in the production of facts, values, plans and visions about the landscape. Still though, community maps at Green Map seems to be a bias towards the values of sites and points, a bias that might miss social and ecological linkages across the landscape, which is of concern for the generation of ecosystem services and ecological resilience. Another problem seems to be the openess of the map-making process. When zooming into the Stockholm Green Map one will also find gasoline stations (selling biofuels), restaurants (serving eco-food) and clothing stores. The map becomes a mosaic of quite non-related things vaguely placed under the umbrella of an urban sustainable lifestyle. A coherent narrative is missing that can bring out negreen-map-chiyen-community-taiwanw perspectives and knowledges of urban realities so as to change spatial planning processes.

Framed as a tool for organized public interests like urban (social) and environmental movements, however, this type of mapping could be valuable in visualizing surpressed values and forsaken spatial realities. As such it could enrich knowledge(s) needed for building more equitable and resilient cities.

Observing social-ecological patterns

The Boston Globe weblog the Big Picture has an online series (23 photos) of fantastic images from NASA’s Earth Observatory site itself.  Below are two smaller versions of the images:

#3 South of Khartoum, Sudan, where the White and Blue Nile Rivers join, a dizzying arrangement of irrigated fields stretches out across the state of El Gezira. The several bare-looking patches are small villages. This image was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite on December 25, 2006.

Mapping global fires

Global Fires : Image of the Day from NASA Earth Observatory:

Like plants, fire activity grows and wanes in seasonal patterns. Globally, fires peak in July, August, and September, when summer’s drying heat makes vegetation flammable and lightning ignites the landscape. In addition, summer is the time when many crops are harvested and fields are burned in the Northern Hemisphere, where most of Earth’s continents are. On any given day in July, August, or September an estimated 6,000 fires burn across the world. February is the slowest month of the year, with an estimated 3,000 fires per day. To watch fires move across the globe throughout the year, see Fire in the Global Maps section of the Earth Observatory.

The contrast between the two months is shown in this pair of images made from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. The top image shows all of the fires detected during August 2008, while the lower image shows February 2008. Dense fire concentrations are yellow, while more scattered fires are red. February is clearly the burning season in the tropics. A solid band of red stretches across the Sahel of Africa, and hundreds fires were burning in northern South America, Central America, and southeast Asia. In August, the fire regions shifted into more temperate regions north and south of the Equator. Intense agricultural fires burn in south-central Europe and in southern Africa.

An animation of global fires is available on the Global Maps section of the NASA Earth Observatory

Mapping the world’s ‘intact’ forests

In the latest issue of Ecology and Society, Peter Potapov et al’s article Mapping the world’s intact forest landscapes by remote sensing. (Ecology and Society 13(2): 51). Shows a new map of global forests – showing the “intact forest” areas that are not directly transformed by human action.

World's intact forest

The world’s intact forest landscapes (IFLs): IFL (green), Forest zone outside IFL (yellow).

The authors define an intact forest area as:

as an unbroken expanse of natural ecosystems within the zone of current forest extent, showing no signs of significant human activity, and large enough that all native biodiversity, including viable populations of wide-ranging species, could be maintained. Although all IFLs are within the forest zone, some may contain extensive naturally treeless areas, including grasslands, wetlands, lakes, alpine areas, and ice.

The data can be downloaded from the projects website as tiff, google earth, or shapefiles.

Compared to other global forest areas assessments the authors found:

  • significantly less intact area in boreal forests than the World’s Wilderness Areas analysis (McCloskey and Spalding 1989) and the Frontier Forests analysis (Bryant et al. 1997) because of our more recent data allowing us to capture the effect of the expansion of oil and gas extraction infrastructure in Canada and Siberia, as well as the role of extensive human-caused fires accompanying industrial development of northern forests.
  • more intact areas in dense tropical forests (the Amazon and Congo basins) and in boreal mountains (southern and eastern Siberia, Kamchatka, Alaska, and the Canadian Rocky Mountains) than was found in previous studies based on coarse-scale map and expert data analysis.
  • the Human Footprint data set (Sanderson et al. 2002), which finds a significantly larger area to be intact within boreal regions and the southern part of the Amazon Basin in Brazil. Both areas were developed (by industrial logging and oil and gas extraction in Canada and Russia, and by agricultural clearing in Brazil) in recent decades, and these changes were not captured in the Human Footprint assessment.
  • in some regions (i.e., Central Africa, boreal forests in Siberia and Canada) we found a smaller area to be intact than the Human Footprint map because we classified burned areas in the vicinity of infrastructure as not intact.
  • The Landscape Domestication Analysis by The Nature Conservancy, which relied on existing transportation network maps, also overestimated the intact area (Kareiva et al. 2007).

Visualization – Processing – a new tool

Still from Radiohead contest video, 2008. Robert HodginFrom International Herald Tribune, New tools to help with information overload:

There’s one simple reason why visualization is becoming so important, and that’s our desire to understand what’s happening in the world at a time when it’s becoming harder and harder to do so. “Design always moves where it is needed most,” said Paola Antonelli, curator of Design and the Elastic Mind, who is now working on a major visualization project. “The surge in computing power has generated a surge in information output, and heated up interest in visualization design.”

…The challenge of presenting information clearly has become more difficult as the volume of data has exploded, and new types have emerged. …

Producing visualization required the development of new tools capable of analyzing huge quantities of complex data, and interpreting it visually. In the forefront is Processing, a software system devised by the American designers, Ben Fry and Casey Reas, to enable computer programmers to create visual images, and designers to get to grips with programming. “Processing is a bridge between those fields,” said Reas. “Designers feel comfortable with it because it enables them to work visually, yet it also feels familiar to programmers.” …

Processing and other types of visualization software also encourage people from different disciplines to work together, at a time when collaboration is increasingly important in creative fields like design. “Visualization is not simply an evolution of graphic design, but a complete and complex design form that requires spatial, narrative, synthetic and graphic sensitivity and expertise,” explained Antonelli. “That’s why we see so many practitioners – architects, product designers, filmmakers, statisticians and graphic designers – flocking to it.”

Below is an ecological model interface made by Neil Banas using Processing:

… these models represent the cycling of nitrogen through plankton populations: we track nitrogen because it is the limiting factor controlling phytoplankton growth (along with light) along the Pacific Northwest coast, as in many places. Circles represent stocks of nitrogen, either dissolved, inside living cells, or in the form of “detritus” (which here really just means “other.”) Arrows represent fluxes between these stocks, like growth, predation, decay, and so forth. The slider at the top lets you control the speed of the simulation; the sliders on the right let you explore the effect of some of the adjustable parameters in each model case.

Visualizing the great acceleration – part ii

The New Scientist adapted graphs from Will Steffen’s and others 2004 Global Change and the Earth System: A Planet Under Pressure for their feature How our economy is killing the Earth.

The three graphs show

  1. first how various drivers of change have accelerated,
  2. how these human changes have driven change in the Earth system, and finally –
  3. when these graphs are combined the accelerating growth of human civilization’s impact on the planet is clear.
