Postdoc on urban social-ecological systems in Boston

A postdoctoral position is available to examine urban greening as a key form of urban land use-land cover change in the greater metro region of Boston, MA. The project involves an interdisciplinary team of social-ecological system researchers at UMass Amherst and 7 other institutions, including Clark University and the Urban Ecology Institute. The successful candidate will be an integral member of this team and will conduct spatial analysis on the current state of green infrastructure and greening interventions in the Boston Metropolitan area.

Research involving the postdoc may include some or all of the following:

  • current and historical patterns of land use and land cover
  • urban food webs and invasive species
  • analysis of river networks and water quality
  • public health issues
  • future scenarios for the Boston Metropolitan area

The successful applicant must be adept at working with multiple researchers with varying interests in urban ecology, including geographers, landscape and urban planners, ecologists, and environmental educators. Strong communication skills are also required for coordinating interviews and meetings. In addition to supporting the overall project, candidates will be encouraged to develop their own research agenda within the project scope.

The preferred start date is January 2011, although there may be some flexibility. The primary location for the postdoc will be at UMass Amherst, but substantial time will need to be spent at other host institutions, and in the city of Boston. This is a one-year position, with the possible extension to two years. Applicants must have relevant Ph.D. experience in ecology, geography, landscape planning, or conservation biology, and be eager to work in an interdisciplinary team with the other scientists on the project. Prior experience with integrating socio-ecology into urban ecosystems is desirable. Candidates with expertise with GIS, modeling, and scenario building, are encouraged to apply.

Review of applicants will begin July 31, 2010, and continue until the position is filled. Applicants should submit (electronically) a cover letter that highlights the applicant’s skills and abilities in areas relevant to this project; curriculum vitae; a one or two page statement of experience as it relates to the stated project goals; a maximum of five sample reprints/preprints (electronic versions); and names, addresses, phone numbers and e-mail addresses of three references.

Josh Cinner, Anna Tsing, and the Meadowlands

Three different takes on thinking about people and nature:

1) A profile of our colleague Josh Cinner in Science (a conservation social scientist):

Now a senior research fellow at James Cook University (JCU) in Townsville, Australia, Cinner studies how coral reefs and people interact in a vast swath of the Southern Hemisphere. “People often have trouble understanding why a social scientist is involved because they think it’s the realm of the marine biologists,” he says. But it makes sense in the context of coral reefs, which are host to dozens of species of fish that provide food and income for nearby villages. “You don’t manage fish. Fish swim and they do their own thing. You manage people. Managing ecosystems is really about managing people and understanding what motivates them and their behaviors.”

Cinner and [Tim] McClanahan have found that different places felt different effects of coral bleaching based on how much people depended on fish and tourism for a living and how flexible the local people were. In Madagascar, rigid taboos govern when people can fish and what gear they can use. “This actually leads to a bit of rigidity and stifles how people are able to adapt,” Cinner says. In Kenya, some people are so desperately poor that when the reefs are in trouble, they just fish harder in the same places. But in the wealthier Seychelles, people have boats that can take them farther out, to target fish that don’t live on the reefs.

These observations have led to ideas about how to protect reefs, and the people who depend on them, during coral-bleaching events. For example, if coral die and algae take over, it’s much harder for coral to get reestablished. But if the reef hosts plenty of parrotfish — which graze on algae and keep the reef clean — the coral will be more likely to come back. Spearfishing particularly targets parrotfish, so one strategy might be to buy back spearfishing gear from Kenyan fishermen to protect parrotfish and make a reef more resilient to climate change, while leaving fishermen with other means to fish.

Cinner wants to extend this work to Indonesia and Papua New Guinea, looking for other ways to help people and coral reefs survive climate change. Working in so many cultures is challenging, he says. “I sometimes have to go through four different languages to remember the word. I might say it in Swahili, Portuguese, and Spanish, and then realize I’m trying to speak Malagasy or something.” He says it’s also tough being away from home so much of the time; last year, he was outside of Australia for about 150 days. But all that is outweighed by the excitement of his research. “You never know what’s going to happen when you step off a bus into a dusty place you’ve never been,” Cinner says. “That feeling never really goes away no matter how many times you do it. It’s almost always worked out for me.”

3) The anthropology blog Savage Minds mentions well-known anthropologist Anna Tsing‘s discussion of the need for alternatives to Actor-Network Theory (which has been discussed on Resilience Science a few times). Savage Minds author Kerim Friedman writes:

Anna Tsing’s current research (or at least what she focused on in her talk) is about mushrooms, focusing on the ways in which mushroom cultivation reuses damaged (“blasted”) landscapes. Drawing on the work of Deborah Bird Rose, she emphasized the way in which these practices allow for a kind of “recuperation” for all the species inhabiting the landscape. She also talked about “multi-species anthropology” as an alternative to Actor-Network Theory. She argued that whereas ANT is useful for inanimate technologies which are animated by their interaction with humans, it is less useful for species which are already alive. Obviously, not all living organisms are relevant to every study, so once again the question of scale is important, and must be determined ethnographically. (See Juno’s Savage Minds review of When Species Meet.)

3) Geoff Manaugh of BLDGBLOG writes about two books on New Jersey’s Meadowlands, a feral landscape within greater New York City.  He writes:

“Just five miles west of New York City,” the back cover of Sullivan’s book reads, are the Meadowlands: “this vilified, half-developed, half-untamed, much dumped-on, and sometimes odiferous tract of swampland is home to rare birds and missing bodies, tranquil marshes and a major sports arena, burning garbage dumps and corporate headquarters, the remains of the original Penn Station, and maybe, just maybe, of the late Jimmy Hoffa.” It is “mysterious ground that is not yet guidebooked,” Sullivan writes inside, “where European landscape painters once set up their easels to paint the quiet tidal estuaries and old cedar swamps,” but where, now, “there are real hills in the Meadowlands and there are garbage hills. The real hills are outnumbered by the garbage hills.”

Lutz’s book describes the region as a “32-square-mile stretch of sweeping wilderness that evokes morbid fantasies of Mafia hits and buried remains.” As Lutz explained in a 2008 interview with Photoshelter, “When I first saw the Meadowlands I was completely blown away at this vast open space with the Manhattan skyline in the distance. It was this space that existed between spaces, somewhere between urban and suburban all the while made up of swamps, towns and intersecting highways. None of it made any sense to me, still doesn’t.”

All told, the area has become, Sullivan writes, “through negligence, through exploitation, and through its own chaotic persistence, explorable again.”

Food history: Social change & tortilla technology

On the weblog Edible Geography Nicola Twilley presents a talk by and profile of Rachel Laudan, a historian of food, at Fueling Mexico City: A Grain Revolution:

All cities require fuel: oil, gas, electricity, and so on. What I want to talk about today is the energy that fuels the people in the cities—food. Without food energy, a city is nothing. A city is nothing without the people who work and play and enjoy or suffer through the city, and they require food.

I want to talk in four short bursts. The first is about what all cities need in the way of food. The second is the reason why Mexico City had a particularly hard time with food. The third describes a revolution in the food of Mexico City that has taken place in the twenty years since I first saw it. And the fourth is about the kind of trade-offs that had to be made to undergo that revolution in food.

On her own blog Rachel Laudan writes about why the Columbian exchange was a non-event in culinary history:

Ok, what do I mean by culinary history?  Culinary (from the Latin culina, kitchen) history traces the history of the (guess) the kitchen or more generally, the techniques used to turn plants and animals into food.

Thesis. 1492 (or the Columbian Exchange) is a complete non-event in culinary history.

Why?  Well, the kitchens and techniques that went from Old World to New were imposed on top of older Mesoamerican techniques.  The result was a two-tier cuisine.  The Spanish kitchen for those of Spanish ancestry, the Mexican kitchen for everyone else.

Or water mills, copper pots, bench stoves, bread ovens for the first lot, grindstones, pottery, three stones round the hearth to balance a griddle, for the latter.  Result–a thin layer of Catholic European Cuisine spread over the local cuisines.

More important what about the kitchens and techniques that went from the New World to the Old.  Zilch, nada. …

Consider three culinary techniques that the Old World could have picked up.

1.  Treating maize with an alkali.  The culinary advantage.  You can make a flexible flatbread with this.  Preferred by most people to the porridges and gruels that were the common way of eating maize in the Old World, maize not treated with alkali not lending itself to flat or raised bread preparations.

2. Making a vegetable puree sauce.  Eventually the Old World figured out how to do this with tomatoes.  But not with chiles, not as thickeners, and not with tomatillos which give a lovely acid taste and great thickening power.  Very little use of rehydrated dried chile in this capacity. Where are the tomatillos in Europe?  Where are the chiles used as the thickeners and flavorers of sauces (instead of simply as  a piquant taste).

3.  Turning cacti/agave into really useful foods.  The paddle cactus is perfect as a green vegetable and grows in arid regions.  The agave yields a drinkable liquid in arid regions and can be turned into a syrup or an alcohol without much trouble.  Yet although these now grow all over the arid regions of Eurasia they are used at most as animal food.

But not a one.  So far as I know, no cooks were brought over from the New World, no systematic exploitation of processing methods from that part of the world.

short links: open data, candian census, and merchants of doubt

1) An Open Data Litmus Test: Is There a Download Button from Off the Map

In order for any data to be open you need to be able to download the data so that you can remix, reuse and share the data. Data and the government agency that supplies it are not transparent if you can’t download the raw data. PDF’s and web services don’t count. They can be useful additions to the raw data, but they are not a replacements.

2)  Idiotically the Canadian government is planning to stop collecting detailed census data.  As the Toronto Globe and Mail explains:

For the first time in 35 years, the census will not feature a detailed, long form that Canadians are obliged to send back to the government.

Users of census information, including myself, are not happy and somewhat puzzled as to why this decision was made.

3) Historians of science Naomi Oreskes and Erik Conway’s new book  Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming, describes how politically connected scientists have operated effective campaigns to skew public opinion towards the denial of well-established scientific knowledge over four decades, now has a website – merchantsofdoubt.org – that links to a bunch of the documents supporting the books arguemnet. I linked to a lecture based on the book earlier this year, and they recently wrote an article based on their book for Yale360 Global Warming Deniers and Their Proven Strategy of Doubt.

Postdoc on dynamic models of vulnerability in drylands and coastal zones

The Law and Governance Group focuses on the role of law and governance in the domains of food and natural resources is looking for a post-doc to work on a collaborative project with the Netherlands Environmental Assessment Agency (PBL) and CERES Research School in the domain of global environmental change :

The post-doc will work in a team with another postdoc on analysis of vulnerability patterns on building bridges between system dynamic models and qualitative case-studies by attempting to upscale lessons learned from local case-studies through Qualitative Comparative Analysis (QCA) and by down-scaling Integrated Assessment Models (IAMS) through cluster analysis of model outcomes. Both strands of the project come together in analyzing patterns of vulnerability. The project will focus on drylands and coastal zones. The post-docs will work in close collaboration with a team of experts from CERES research school and the PBL. The postdoc will be responsible for the down- scaling of Integrated Assessment Models.

The research is carried out in Wageningen and partly at the Netherlands Environmental Assessment Agency in Bilthoven, and should lead to a development of methodology and a number of high quality publications.

You have a PhD degree in social or natural sciences; a strong interest in and experience with modeling (preferably system dynamics), sensitivity for qualitative research, experience with research on (global) environmental change, and interdisciplinary work. You are a team worker and have excellent writing and communication skills and a proven ability to publish cutting-edge scientific papers in peer-reviewed journals and an excellent command of English

2011 Smith Fellowships Annoucement

I had a Smith Fellowship during my post-doc and it was a good experience.  The 2011 call is open now, and they are open to individuals who want to extend the social-ecological frontiers of conservation biology.

The Society for Conservation Biology is pleased to solicit applications for the David H. Smith Conservation Research Fellowship Program. These two year post-doctoral fellowships enable outstanding early-career scientists to improve and expand their research skills while directing their efforts towards problems of pressing conservation concern for the United States.

Each Fellow is mentored by both an academic sponsor who encourages the Fellow’s continued development as a conservation scientist, and a conservation practitioner who helps to connect the Fellow and her/his research to practical conservation challenges.

Fellows will spend up to four weeks per year during their fellowship attending orientation and training events. These offerings provide opportunities to cultivate professional networks and to gain better understanding of applied research needs. Fellows will participate as a group in three or more of these Program-sponsored meetings, conferences, or professional development events each year.

The Program especially encourages individuals who want to better link conservation science and theory with pressing policy and management applications to apply. We envision that the cadre of scientists supported by the Smith Fellows Program eventually will assume leadership positions across the field of conservation science. Fellows are selected on the basis of innovation, potential for leadership and strength of proposal.

The deadline for receipt of application materials is 24 September 2010. The Program expects to select four Fellows in January 2011 for appointments to start between March and September 2011. Fellowship awards include an annual salary of $50,000, benefits, and generous travel and research budgets. For detailed proposal guidelines, please visit http://www.conbio.org/smithfellows/apply/. Questions may be directed to Shonda Foster, Program Coordinator, by emailing sfoster@conbio.org.

Critical Reflections on resilience thinking in the Transition Movement

The Resilience Alliance website has pointed to an interesting working paper from Alex Haxeltine, and Gill Seyfang from the Tyndall Centre in the UK Transitions for the People: Theory and Practice of ‘Transition’ and ‘Resilience’ in the UK’s Transition Movement, whose focus on developing transition towns to respond to the challenges of climate change and peak oil we have covered before on this blog.

Haxeltine and Seyfang state they write as ‘critical friends’ of the transition movement and address the transition movements equation of localism with resilience (which I believe is incorrect, and likely counterproductive).  It is wonderful to see resilience researchers engaging with they dynamic transition movement.  They write:

The specific language used is of “rebuilding resilience” – drawing on historical descriptions of towns in the UK around 100 years ago, the handbook argues that resilience has been decreased in recent decades. The narrative describes how localised patterns of production and consumption (and the associated skill sets and community cohesion) were eroded in a relentless shift to ever larger scale industrialized systems of production and consumption, made possible by the use of fossil fuel energy sources. Hopkins argues that there is now a great urgency to the need to rebuild resilience because of imminent disturbances (or shocks) in the form of peak-oil, climate change, and the associated impacts on economic systems and trading patterns (Hopkins, 2008). He links this urgency directly to our current oil dependency: “it is about looking at the Achilles heel of globalization, one from which there is no protection other than resilience: its degree of oil dependency” (Hopkins, 2008).

The framing of the Transition model provided in the handbook does explicitly draw upon the academic literature on resilience in socio-ecological systems (citing a 2006 introductory text by Brian Walker and David Salt for example), but what ideas are being taken from this literature, and to what extent is the resulting framework consistent with the interpretation of resilience quoted in section 2 of this paper? The Transition Handbook (Hopkins, 2008) cites studies of what makes ecosystems resilient, identifying: diversity, modularity and tightness of feedbacks:

These initial resilience indicators rely heavily on equating resilience with the re-localisation of systems of production and consumption. So the Transition Handbook could be said to provide a starting point for talking about resilience in a Transition Town, but it is still a long way from being clear about what is needed in practice. Furthermore the evidence from observation of the local Transition groups (during 2008-2009) is that they are in an equivalent situation of trying to frame multiple actions in terms of the building of resilience but relying heavily on equating resilience with a re-localisation of production-consumption patterns.

Resilience theory highlights the fact that building resilience to a specified disturbance (such as Peak Oil) does not necessarily provide the same resilience to all possible disturbances. Some properties of a Transitioning community, such as strong community networks and diverse skill sets, may help provide resilience to most disturbances, while other properties may be very specific to one disturbance. If one were to take the position that the greatest shocks in the coming years may, in the end, turn out not to be the ones that we expected, then successfully building a specific resilience to an expected threat (such as Peak Oil) may not provide resilience against realized disturbances. So what may be required is to build resilience to specific threats in a way that also builds system properties that help in coping with diverse possible threats – implying, for example, a need for a capacity to innovate.

The current framing of resilience equates resilience with localisation in a rather unquestioning way, as demonstrated by the resilience indicators given in the Transition Handbook. We would argue that increasing any one of these indicators could actually either increase or decrease resilience to a specific disturbance, depending the exact nature of the disturbance and on the exact systemic changes used to enhance the indicator. We also argue that the desirable goal is not to simply increase such indicators as much as possible, but to find the right balance between resilience and other goals, such as quality of life and well being.

IPBES – a new assessment of Biodiversity and Ecosystem Services

Five years after the Millennium Ecosystem Assessment, the first assessment of the Earth’s ecosystem services, was released the Intergovernmental Panel on Climate Change, the Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services (IPBES) has been proposed to carry out regular scientific assessments of the what science knows about biodiversity and ecosystem services.

While there has been substantial agreement that a followup to the MA was needed there has not been agreement on how to do it.  Like the MA, this new panel will be modelled on the IPCC and it will probably meet in 2011.   It is supposed to conduct periodic assessments of biodiversity and ecosystem services at global, regional and sub-regional scales that address policy relevant questions, identify research gaps, and build capacity to address these issues.

The MA had a huge impact on the research community, changing the questions that many scientists, including myself decided to address.  Hopefully, this new panel will provide a useful focus for ecosystem service research, however I worry a bit about an over focus on biodiversity, and a lack of attention to agriculture, soils, water, and social change all of which are essential to understand ecosystem services.

Also while there has been ongoing concern about how to create and fund an ecosystem service assessment, and has also been a lot of concern over who would operate it (i.e. that it have a strong scientific foundation), as well as how it will fit with ongoing global change research programs such as IHDP and PECS, as well as DIVERSITAS. These things remain unclear for IPBES.

Nature reports:

In Busan, negotiations stretched late into the night as delegates debated the scope of the proposed IPBES, including the specifics of how it will be funded. “There was concern among the developed countries that this not become a huge bureaucracy,” says Nuttall. “Governments wanted to be reassured that it would be lean and mean and streamlined.”

Another bone of contention was to what extent IPBES would tackle emerging issues or areas of contested science. In the end, it was agreed that the body will draw attention to “new topics” in biodiversity and ecosystem science. “If there had been something like this before, then new results on issues such as ocean acidification, dead zones in the ocean and the biodiversity impacts of biofuels would have been rushed to the inboxes of policymakers, instead of coming to their attention by osmosis,” says Nuttall.

Among the governments who assented to the IPBES’s creation were the European Union, the United States, and Brazil. The plan will come before the general assembly of the United Nations, slated to meet in September, for official approval. Those involved with the process say that that the UN creation of the new body is a virtual certainty.

It will be interesting to see how IPBES evolves. I think it is very important that an excellent team of broad thinking scientists with experience in large scientific assessment are chosen to lead this project.

Systems theorist Vladimir Arnold has died

Vladimir Arnold from WikipediaVladimir I. Arnold one of the major creators of dynamical systems theory used to represent ecological regime shifts died June 3rd this year.

He was one of the creators of the mathematics behind what is known as catastrophe theory and singularity theory which are used to represent regime shifts.  The New York Times writes:

Singularity theory predicts that under certain circumstances slow, smooth changes in a system can lead to an abrupt major change, in the way that the slipping of a few small rocks can set off an avalanche. The theory has applications in physics, chemistry and biology.

“He was a genius and one of the greatest and most influential mathematicians of our time,” said Boris A. Khesin, a former student of Dr. Arnold’s and now a professor of mathematics at the University of Toronto.

One of Dr. Arnold’s biggest contributions was applying the methods of geometry and symmetry to the motion of particles. Dr. Arnold work on how fluids flow was applied to the dynamics of weather, providing a mathematical explanation for why it is not possible to make forecasts months in advance. Infinitesimal gaps or errors in information cause forecasts to diverge completely from reality.

A similar approach can also be applied to the motion of planets. If Earth were the only planet to circle the Sun, its orbit would follow a precise elliptical path, but the gravity of the other planets disturbs the motion. Scientists found that it impossible to calculate the precise motion of the planets over very long periods of time or even prove that Earth will not one day be flung out of the solar system.

Understanding the subtle and difficult-to-predict boundary between stability and instability is important not only in the study of planetary dynamics but also in other endeavors, like designing a nuclear fusion reactor.

In 1954, the Russian mathematician Andrey Kolmogorov figured out a key insight to calculating whether such systems are stable. Dr. Arnold provided a rigorous proof in 1963 for one set of circumstances. Another mathematician, Jürgen Moser, provided the proof for another. The work is now collectively know at the KAM theory.

Andrew Gelman’s Statistical Modeling weblog

Well known statistician Andrew Gelman and his colleagues write an informative and interesting weblog Statistical Modeling, Causal Inference, and Social Science on the quantitative side of the social sciences (which has a lot that ecologists or sustainability scientists can learn from).  Below are some of the recent posts that I found informative and interesting:

1) Suggestions on how to best learn R

2) A data visualization manifesto

At a statistical level, though, I think the details are very important, because they connect the data being graphed with the underlying questions being studied. For example, if you want to compare unemployment rates for different industries, you want them on the same scale. If you’re not interested in an alphabetical ordering, you don't want to put it on a graph. If you want to convey something beyond simply that big cars get worse gas mileage, you’ll want to invert the axes on your parallel coordinate plot. And so forth. When I make a graph, I typically need to go back and forth between the form of the plot, its details, and the questions I’m studying.

3) Testing effectiveness of different approaches to data visualization

Jeff Heer and Mike Bostock provided Mechanical Turk workers with a problem they had to answer using different types of charts. The lower error the workers got, the better the visualization. Here are some results from their paper Crowdsourcing Graphical Perception: Using Mechanical Turk to Assess Visualization Design

4) Novels as perturbations of our models of reality

I used to think that fiction is about making up stories, but in recent years I’ve decided that fiction is really more of a method of telling true stories. One thing fiction allows you to do is explore what-if scenarios. I recently read two books that made me think about this: The Counterlife by Philip Roth and Things We Didn’t See Coming by Steven Amsterdam. Both books are explicitly about contingencies and possibilities: Roth’s tells a sequence of related but contradictory stories involving his Philip Roth-like (of course) protagonist, and Amsterdam’s is based on an alternative present/future. (I picture Amsterdam’s book as being set in Australia, but maybe I’m just imagining this based on my knowledge that the book was written and published in that country.) I found both books fascinating, partly because of the characters’ voices but especially because they both seemed to exemplify George Box’s dictum that to understand a system you have to perturb it.
