Video Tutorial on Social Network Analysis Using R

From the Complexity and Social Networks Blog links to video of Steve Goodreau and David Hunter running a tutorial on Social Network Analysis Using R.  They recommend some prior knowledge of R and standard network analytic methods as the tutorial covers:

  • use of exponential random graph (ERG or p*) models for representing structural hypotheses,
  • model parameterization, simulation and inference,
  • degeneracy checking, and goodness-of-fit assessment.

For more information, please see the workshop web page, or our project home page .

Congratulations to my colleague, Johan Rockström, director of the Stockholm Resilience Centre and SEI, who has been named Swedish Person of the Year by FOKUS magazine

for his engaging and exciting work for sustainable development.

The Stockholm Resilience Centre has a press release about the award in which Johan states:

I am immensely honored to receive this award, above all on behalf of my many colleagues whose work deserves this attention. Both SEI and Stockholm Resilience Centre conduct enormously important work to support sustainable development in both rich and poor countries. This also includes the importance of actively communicating their work to policymakers and society as a whole, Rockström says.

Modelling climate trajectories in Copenhagen

My systems modelling colleague Tom Fiddaman has been working to develop a policy screening simulation model to aid with climate negotiations.  He and his colleagues at Climate Interactive have developed a simple integrated energy and climate model C-ROADSSome negotiators are running on their laptop computers to evaluate alternate proposals.  Climate Interactive are using it at COP15 to provide dynamic updates of the consquences of different policy proposals.  An updated figure is shown in the figure above.

On the Climate Interactive website they write:

…how close do current proposals bring the world to climate goals such as stabilizing CO2 concentrations at 350ppm or limiting temperature increase to 2°C? The challenges of adding up proposals that are framed in multiple ways and the difficulty of determining long-term impacts of any given global greenhouse gas emissions pathway are just as present for citizens as they are for policy makers and political leaders.

With these facts in mind, our team is tracking the proposals under consideration and using the same climate change simulation available to policy-makers to report our estimate of how close ‘current proposals’ come to realizing climate goals. And we are aiming to do it in real-time as the summit unfolds.

Calculations in the Climate Scoreboard are made in C-ROADS, a scientifically reviewed climate simulator built using the system dynamics methodology that is designed to aggregate the proposals of 15 countries and country groups and calculate the climate impacts such as carbon dioxide concentration and temperature.  C-ROADS was built by Sustainability Institute, Ventana Systems, and the Sloan School of Management at MIT.

Follow these links to understand more about C-ROADS, explore its site, read the scientific review, read the reference guide, read user quotes, read the “Frequently Asked Questions”, or experiment with the online, CO2-focused, three region version, C-Learn.

To view more Scoreboard results beyond the temperature values shown in the “widget” image, view the table of proposals, download a PowerPoint file with graphs, consult the “Frequently Asked Questions” and view an Excel file that includes a table of references for the proposals, lists our modeling assumptions, and shares C-ROADS output for the proposals.

Climate vs. Tobacco

Tobacco and public health researcher Maria Nilsson and others have a Comment in the Lancet Climate policy: lessons from tobacco control (doi:10.1016/S0140-6736(09)61959-0) in which they compare the policy response to the public health problems of tobacco to climate policy:

Controlling tobacco use is the highest immediate priority for global health, while climate change is the biggest threat to health in the medium and long term. The longstanding efforts to control the impact of the tobacco industry have important lessons for climate control.

Both health threats are underpinned by scientific evidence of increasing robustness. …
There are many similarities between tobacco use and climate change. In addition to causing huge damage to population health, both cause substantial adverse social, economic, equity, and gender effects. Both have long lead times between cause and effect, and both require long-term policies and monitoring systems. The number of countries implementing the policies effectively is far too low. Negative effects are increasing over time and will have greatest effects in low-income countries and poor populations. Both issues are influenced by strong vested interests; moreover, delaying tactics and the use of “junk science” by opponents of change have impeded effective policies.

Climate change can be compared to passive smoking because those who generate the damage are not the same people as those who suffer (in the case of tobacco) or the same country (in the case of climate change); greenhouse gases are the largest externality the world has ever experienced.

Externalities require public policy intervention because markets cannot and will not deal with them. As with tobacco use, climate change requires local action informed by local circumstances. But in both cases, solutions ultimately depend on globally coordinated policies.

There are also important differences. The health damage due to smoking accrues either directly to smokers or indirectly to others through passive smoking. The effects from climate change will be global; those countries responsible for the most cumulative emissions are much less damaged than those who suffer most from the health effects.

There are important lessons from tobacco control for climate policy. The existing research base calls for urgent, comprehensive, and sustained action. Political will and strong leadership are required for both areas: implementing effective tobacco control policies has taken decades and is far from complete. Additional funding to support action in low-income countries is in the interest of all. The main lesson from tobacco for the Copenhagen conference is that delay in agreeing on international policy and poor implementation will cost countless lives. We must act now in the interests of future generations.

The non-suprising dynamics of climate change

On his weblog Open Mind Tamino makes some graphs of decadal climate change.  He writes:

Those who are in denial of global warming insist that the last decade of global temperature contradicts what was expected by mainstream climate scientists.

Here’s global temperature data from NASA GISS before the 21st century, for the time span 1975 to 2000:

I’ve computed and plotted a trend line using linear regression. In addition, I’ve plotted dashed lines two standard deviations above and below the trend line — we expect most of the data to fall within these dashed lines. Finally, I’ve projected those lines out to the present day.

That’s what mainstream climate scientists expected to happen.

Here’s what actually happened.

Gosh. What actually happened is exactly what was expected. Exactly. By mainstream climate scientists. You know, those folks who keep telling us that human activity is warming the planet and that it’s dangerous.

Tamino also shows that various alternative climate data sets show the same pattern. And as Nature reports the UK Met Office shows the last decade was the warmest recorded, since instrumental records began in 1850.

Plastic within the biosphere

American photographer Chris Jordan organized a a trip to Midway Atoll, three small islands in the North Pacific, located about halfway between the U.S. and Asia, and was the location of the battle of Midway.  Now the atoll is also near the centre of the Pacific Trash Vortex, where the North Pacific Gyre concentrates the plastics that are swept into or dumped in the world’s oceans.

Chris Jordan photographed the decaying body’s of dead albatross chicks full of plastic they have consumed.

plastic

He writes:

These photographs of albatross chicks were made just a few weeks ago on Midway Atoll, a tiny stretch of sand and coral near the middle of the North Pacific. The nesting babies are fed bellies-full of plastic by their parents, who soar out over the vast polluted ocean collecting what looks to them like food to bring back to their young. On this diet of human trash, every year tens of thousands of albatross chicks die on Midway from starvation, toxicity, and choking.

To document this phenomenon as faithfully as possible, not a single piece of plastic in any of these photographs was moved, placed, manipulated, arranged, or altered in any way. These images depict the actual stomach contents of baby birds in one of the world’s most remote marine sanctuaries, more than 2000 miles from the nearest continent.

More (and larger) photos are on his site.

Agro-colonialism and/or Agricultural development?

The New York Times Magazine has an article by Andrew Rice Is There Such a Thing as Agro-Imperialism? on new mega-investments in agricultural land in Africa.

This type of activity featured in the Millennium Ecosystem Assessment‘s TechnoGarden scenario as something that can have complicated ecological and social consequences. These investments often displace small scale farmers, but can greatly increase yields.  Indirectly they can benefit local people enhancing local agricultural infrastructure, skills, and economic opportunities – or they can just degrade local ecosystems for external benefit.  The article sets the stage and provides some examples from Ethiopia:

Investors who are taking part in the land rush say they are confronting a primal fear, a situation in which food is unavailable at any price. Over the 30 years between the mid-1970s and the middle of this decade, grain supplies soared and prices fell by about half, a steady trend that led many experts to believe that there was no limit to humanity’s capacity to feed itself. But in 2006, the situation reversed, in concert with a wider commodities boom. Food prices increased slightly that year, rose by a quarter in 2007 and skyrocketed in 2008. Surplus-producing countries like Argentina and Vietnam, worried about feeding their own populations, placed restrictions on exports. American consumers, if they noticed the food crisis at all, saw it in modestly inflated supermarket bills, especially for meat and dairy products. But to many countries — not just in the Middle East but also import-dependent nations like South Korea and Japan — the specter of hyperinflation and hoarding presented an existential threat.

“When some governments stop exporting rice or wheat, it becomes a real, serious problem for people that don’t have full self-sufficiency,” said Al Arabi Mohammed Hamdi, an economic adviser to the Arab Authority for Agricultural Investment and Development. Sitting in his office in Dubai, overlooking the cargo-laden wooden boats moored along the city’s creek, Hamdi told me his view, that the only way to assure food security is to control the means of production.

Hamdi’s agency, which coordinates investments on behalf of 20 member states, has recently announced several projects, including a tentative $250 million joint venture with two private companies, which is slated to receive heavy subsidies from a Saudi program called the King Abdullah Initiative for Saudi Agricultural Investment Abroad. He said the main fields of investment for the project would most likely be Sudan and Ethiopia, countries with favorable climates that are situated just across the Red Sea. Hamdi waved a sheaf of memos that had just arrived on his desk, which he said were from another partner, Sheik Mansour Bin Zayed Al Nahyan, a billionaire member of the royal family of the emirate of Abu Dhabi, who has shown interest in acquiring land in Sudan and Eritrea. “There is no problem about money,” Hamdi said. “It’s about where and how.”

All through the Rift Valley region, my travel companion, an Ethiopian economist, had taken to pointing out all the new fence posts, standing naked and knobby like freshly cut saplings — mundane signifiers, he said, of the recent rush for Ethiopian land. … Behind it, we could glimpse a vast expanse of dark volcanic soil, recently turned over by tractors. “So,” said my guide, “this belongs to the sheik.”

He meant Sheik Mohammed Al Amoudi, a Saudi Arabia-based oil-and-construction billionaire who was born in Ethiopia and maintains a close relationship with the Ethiopian Prime Minister Meles Zenawi’s autocratic regime. (Fear of both men led my guide to say he didn’t want to be identified by name.) Over time, Al Amoudi, one of the world’s 50 richest people, according to Forbes, has used his fortune and political ties to amass control over large portions of Ethiopia’s private sector, including mines, hotels and plantations on which he grows tea, coffee, rubber and japtropha, a plant that has enormous promise as a biofuel. Since the global price spike, he has been getting into the newly lucrative world food trade.

Ethiopia might seem an unlikely hotbed of agricultural investment. To most of the world, the country is defined by images of famine: about a million people died there during the drought of the mid-1980s, and today about four times that many depend on emergency food aid. But according to the World Bank, as much as three-quarters of Ethiopia’s arable land is not under cultivation, and agronomists say that with substantial capital expenditure, much of it could become bountiful. Since the world food crisis, Zenawi, a former Marxist rebel who has turned into a champion of private capital, has publicly said he is “very eager” to attract foreign farm investors by offering them what the government describes as “virgin land.” …

By far the most powerful opposition, however, surrounds the issue of land rights — a problem of historic proportions in Ethiopia. Just down the road from the farm on Lake Ziway, I caught sight of a gray-bearded man wearing a weathered pinstripe blazer, who was crouched over a ditch, washing his shoes. I stopped to ask him about the fence, and before long, a large group of villagers gathered around to tell me a resentful story. Decades ago, they said, during the rule of a Communist dictatorship in Ethiopia, the land was confiscated from them. After that dictatorship was overthrown, Al Amoudi took over the farm in a government privatization deal, over the futile objections of the displaced locals. The billionaire might consider the land his, but the villagers had long memories, and they angrily maintained that they were its rightful owners.

An international workshop on Social-Ecological Resilience of Cultural Landscapes

A workshop on resilience and cultural landscapes is going to be held in Berlin, Germany from 15 to 16 June 2010.  It is currently calling for papers (see below).  The workshop is described in a downloadable pdf.

It states:

The workshop aims to provide an interdisciplinary forum for about 20 PhD students, post-docs, and senior researchers from all fields of landscape research, including geography, landscape ecology, institutional economics, rural sociology, agricultural and forest sciences, and land change science.

Drawing on case studies provided by participants, the workshop aims at creating, respectively enhancing, theoretical insights into the social-ecological resilience of cultural landscapes through coming to terms with – and challenging – existing concepts of “driving forces”, “thresholds”, “adaptive cycles” and “adaptive management”. We expect that an improved understanding of these issues will facilitate the fostering and advancement of future research on the resilience and sustainable management of cultural landscapes.

The basis of the workshop, and starting point for extensive discussion sessions, will be empirical studies focusing on cultural landscapes as social-ecological systems. We are especially looking forward to contributions linking ecological analysis with insights into the social processes tied to changing cultural landscapes.

Specifically, we call for papers that:

  • analyze drivers at different temporal and spatial scales for determining the state of cultural landscapes;
  • identify thresholds and regime shifts that result from crossing these thresholds;
  • examine ways to enhance the resilience of cultural landscapes so as to avoid shifts towards undesired structural or functional states;
  • discuss the contributions that the adaptive cycle provides for the understanding of cultural landscape dynamics;
  • specify adaptive management strategies for the restoration of natural and social capital in traditional or “novel“ cultural landscapes;
  • contrast the “social-ecological systems” perspective with the “cultural landscape” concept.

The outcome of the workshop is to be published either in an edited book or in a special issue of a relevant journal. The geographic focus of the workshop will be on Europe, but reference to other cultural landscapes of the world is also welcome

Please send an abstract (ca. 300 words) to Claudia Bieling or Tobias Plieninger by 28 February 2010. Notifications of acceptance will be sent out by 14 March 2010. Final papers are due by 30 May 2010.

Costs of participation in the seminar will be covered. Participants are expected to bear expenses for transportation and accommodation themselves. To a limited extent, we can additionally provide travel support to people who would be unable to attend the workshop otherwise. If applicable, send your request for financial assistance together with your abstract.

The workshop will include keynote presentations by:

  • Mauro Agnoletti, University of Florence (Italy)
  • Carole Crumley, University of North Carolina at Chapel Hill (USA) / Stockholm Resilience
  • Centre (Sweden)
  • Lesley Head, University of Wollongong (Australia)
  • Ann Kinzig, Arizona State University (USA)
  • Mats Widgren, Stockholm University (Sweden)

Connect: a chaotic sculpture

Andreas Muxel‘s Connect, won the 2009 Share Prize.  The prize jury writes:

This mesmerizing installation, with its precarious mixture of bouncing rubber and flying steel, is like a world financial crisis all by itself. With simple but powerful elements, “Connect” generates endless dramatic episodes of comical failure and heroic determination. The vital network of “Connect” won’t stop changing, and we can’t stop looking at it.
