Human Development 2010


Two videos from UNDP related to the release of the 2010 Human Development Report Nov 4, 2010. This report was founded twenty years ago, and as the videos describe, most countries in the world have made major gains in Human Development during that time.

What’s driving current food prices?

New Scientist interviewed food policy researchers Maximo Torero and Joachim von Braun from IFPRI about current rise in food prices and they blame financialization of commodity markets:

Is this another crisis like the one we had in 2008?

Not quite. Maximo Torero of the International Food Policy Research Institute (IFPRI) in Washington DC notes that oil, the real driver of food prices and of the 2008 crisis, is relatively cheap, at around $75 a barrel, not over $100 as it was in 2008.

In 2008, both immediate grain prices, and the prices offered for future grain purchases in commodities markets, climbed steadily for months, whereas now they are spiking and dipping more unpredictably, which economists call volatility.

“The market fundamentals – supply and demand – do not warrant the price increases we have seen,” says Torero. Not all harvests have been bad, and after 2008 countries rebuilt grain stocks. “There are enough stocks in the US alone to cover the expected losses in Russia.”

The food riots in Mozambique were not due to world grain prices, he says, but because Mozambique devalued its currency, making imported food more expensive.

So what has been happening this year?

Markets are responding nervously to incomplete information. First there was a series of shocks: Russia’s export ban, lower maize forecasts, then, days later, a US ruling to allow more bioethanol in fuel which seemed likely to further reduce the maize – the main source of bioethanol – available for food. Meanwhile there was no reliable information about grain stocks, which is strategic information that most countries keep secret.

The result was nervous bidding and sporadically surging prices in commodity markets. And that attracted the real problem: investors wielding gargantuan sums of speculative capital and hoping to make a killing. When speculation exacerbated the price crisis of 2008, Joachim von Braun of the University of Bonn, Germany, then head of IFPRI, predicted that it would continue causing problems. “We saw that one coming and it came,” he says. “Food markets have new design flaws, with their inter-linkages to financial markets.”

Volatility also makes it harder to solve the long-term, underlying problem – inadequate food production – by making farmers and banks reluctant to invest in improved agricultural technology as they are unsure of what returns they will get. “Investment in more production alone will not solve the problem,” says von Braun. As long as extreme speculation causes constant price bubbles and crashes, either farmers will not get good enough returns to continue investing in production, or consumers will not be able to afford the food.

“Without action to curb excessive speculation, we will see further increases in these volatilities,” he says.

What is Social Learning?

Ecology and Society has just published a clarifying new paper by Mark S. Reed and others What is Social Learning? (15(4): r1).  Reed and his co-authors argue that while social learning is becoming an increasingly important goal in natural resource management there is little consensus on what social learning actually is, and they attempt to provide a clear definition.

They write [formatting added by me]:

Social learning is often conflated with other concepts such as participation and proenvironmental behavior, and there is often little distinction made between individual and wider social learning. Many unsubstantiated claims for social learning exist, and there is frequently confusion between the concept itself and its potential outcomes. This lack of conceptual clarity has limited our capacity to assess whether social learning has occurred, and if so, what kind of learning has taken place, to what extent, between whom, when, and how. This response attempts to provide greater clarity on the conceptual basis for social learning.We argue that to be considered social learning, a process must:

(1) demonstrate that a change in understanding has taken place in the individuals involved;

(2) demonstrate that this change goes beyond the individual and becomes situated within wider social units or communities of practice; and

(3) occur through social interactions and processes between actors within a social network.

A clearer picture of what we mean by social learning could enhance our ability to critically evaluate outcomes and better understand the processes through which social learning occurs. In this way, it may be possible to better facilitate the desired outcomes of social learning processes.

Writing and the Scientific Process

George Gopen and Judith Swan write in the American Scientist (Nov/Dec 1990) about The Science of Scientific Writing. They write that complex thoughts can be made accessible and clear without minimizing their complexity if a set of structural principles are followed:

  1. Follow a grammatical subject as soon as possible with its verb.
  2. Place in the stress position the “new information” you want the reader to emphasize.
  3. Place the person or thing whose “story” a sentence is telling at the beginning of the sentence, in the topic position.
  4. Place appropriate “old information” (material already stated in the discourse) in the topic position for linkage backward and contextualization forward.
  5. Articulate the action of every clause or sentence in its verb.
  6. In general, provide context for your reader before asking that reader to consider anything new.
  7. In general, try to ensure that the relative emphases of the substance coincide with the relative expectations for emphasis raised by the structure.

…The substance of science comprises more than the discovery and recording of data; it extends crucially to include the act of interpretation. It may seem obvious that a scientific document is incomplete without the interpretation of the writer; it may not be so obvious that the document cannot “exist” without the interpretation of each reader. In other words, writers cannot “merely” record data, even if they try. In any recording or articulation, no matter how haphazard or confused, each word resides in one or more distinct structural locations. The resulting structure, even more than the meanings of individual words, significantly influences the reader during the act of interpretation. The question then becomes whether the structure created by the writer (intentionally or not) helps or hinders the reader in the process of interpreting the scientific writing.

Career development, writing, and teaching resources for graduate students and post-docs

Spencer Hall at the Department of Biology at Indiana University has collected a good collection of  Resources for Graduate Students and Post-Docs that give advice on career development, writing, and teaching:

  1. Advice on being a graduate student and becoming a professional
  2. Grant writing
  3. Advice on getting a faculty job
  4. Advice on good writing
  5. Advice on giving good talks and posters
  6. Guides/thoughts on authorship and reviewing
  7. Teaching
  8. Other people’s webpages for graduate students

He writes:

These resources are meant to offer advice, but they should be considered as food for thought rather than a recipe for success. With that caveat in mind, I hope that you find these documents useful. If you find anything yourself which might be useful to others, please send it along and I will post it.

Again, you may not agree with all of the advice in these documents, or you may not find some articles helpful. Please view everyone’s advice with a healthy dose of skepticism

Phosphorus dynamics – mining vs. recycling

Global P consumption in Millions of Tonnes. Data from FAO.

Phosphorus is essential for sustaining humanity, because it is essential nutrient for producing food, and it is often a limiting nutrient for plant growth. Unlike nitrogen, it cannot be fixed from the air, and must be either recycled or mined.

Modern industrial agriculture relies on continual inputs of mined phosphor. How long phosphorus mining can last is quite uncertain. A new assessment of phosphor supplies suggests these are supplies are much bigger than previously thought.

A recent editorial in Nature Not Quite Assured (Oct 27, 2010)writes:

Reserves of the phosphate rock used to make such fertilizers are finite, and concerns have been raised that they are in danger of exhaustion. It has been argued, for example, that data from the US Geological Survey point to the available supplies peaking in as little as 25 years time (see Nature 461, 716–718; 2009). Because there is no substitute for phosphate in agriculture, this might present an urgent and substantial problem. But initial findings from the World Phosphate Rock Reserves and Resources study conducted this year by the IFDC, an international non-profit organization based in Muscle Shoals, Alabama, and formerly known as the International Fertilizer Development Center, suggest that phosphate rock deposits should last for between 300 and 400 years.

Accurate information about phosphate reserves is hard to come by, and the IFDC concedes that more work is needed to hone its estimates. The mining industry, governments and interested researchers should accept the organization’s invitation to collaborate in this process.

The phosphate issue runs beyond gaining assurances that total global supply will meet demand. There remain important concerns that phosphate and other fertilizers are being squandered in some parts of the world, whereas farmers in other regions cannot obtain them at a reasonable cost.

… current fertilizer-production methods fail to maximize the efficient conversion of phosphate rock into fertilizer. The supply of the rock is heavily concentrated in two nations, China and Morocco, on whose good faith the rest of the world relies for its phosphate supplies. That faith has been shaken by extreme price fluctuations in recent years.

Yet the heavy dependence of food production on fertilizers, inequalities of supply and the need for sustainable use of fertilizers — including recycling — are largely missing from discussions on approaches to sustainable development. They were only mentioned in passing, for example, at the United Nations’ world summit on food security in Rome last November.

Hydrologists, soil researchers and food scientists have begun to raise awareness of some of the issues surrounding phosphates. A discussion will be devoted to the topic at the Crop World 2010 meeting in London next week, in which researchers will be joined by industry and government representatives, including John Beddington, the UK government’s chief scientific adviser, who has worked hard to raise political awareness of food-security issues.

These efforts would be strengthened if an international body, such as the UN Food and Agriculture Organization, started to seriously champion the issue of sustainable fertilizer use. The organization already tracks fertilizer demand and supply, and has produced reports on phosphate fertilizer use. It doesn’t have a specific programme for sustainable fertilizers, but its departments of agriculture and natural resources do some work in this area, giving it a base on which to build. It now needs to push this issue out from the sidelines and into the policy-making process that will shape the future of agriculture and sustainable development.

My colleague Arno Rosemarin believes that the assessment is wrong.  He has co-authored another assessment of phosphor supplies, and comments on the nature editorial:

The statement in the IFDC report that we have 300-400 years prior to depletion og phosphorus is based on a zero increase in extraction from now on. The rate of annual increase is presently in fact 3-4%. Extraction will hopefully decrease as we become more efficient, start significant reuse programmes, etc. But this will take decades and no UN governance or monitoring plan is in sight. The food security summits in 2008 and 2009 never mention the word phosphorus. The new data on increased reserves from IFDC are based almost entirely on a recalculation for Morocco giving them 10 times more phosphorus and 85% of the global capacity. But the estimates are based on a hypothetical calculation and economic viability does not figure in the calculation. There are no data on reserves from industry in the calculation since this is kept confidential.

Ecosystem ecologist Jim Elser followed with:

While this seems like welcome news, as Dr Rosemarin notes, the new estimate is entirely based on a revision of estimates for Morocco and seems to be derived from a 20-year old geological report and not on any new geological survey data. It is also important to note that the 300-400 year IFDC estimate for P depletion is a different event than the timing of “peak phosphorus”, which refers to the date when global P production will occur (previous estimates placed this timing for 2030-2040). It is likely that, even if this new reserve number for Morocco is correct and the P ore there is indeed of high quality and accessible, a production peak for P is likely only pushed back by a few decades. In any case, the key issue for any such commodity is PRICE and what remains to be analyzed is the likely future dynamics of P fertilizer prices in the face of the need to double food production by 2050 while simultaneously satisfying the burgeoning bioenergy industry. “Not quite assured”, indeed.
Is this any way to run a biogeochemical cycle?

Is promoting climate change disinformation a new type of crime against humanity?

Donald Brown,a professor of law and environmental ethics at Penn State University,on his blog Climate Ethics wonders whether funding climate disinformation is A New Kind of Crime Against Humanity?. He writes:

On October 21, 2010, the John Broder of the New York Times, reported, that “the fossil fuel industries have for decades waged a concerted campaign to raise doubts about the science of global warming and to undermine policies devised to address it. According the New York Times article, the fossil fuel industry has ” created and lavishly financed institutes to produce anti-global-warming studies, paid for rallies and Web sites to question the science, and generated scores of economic analyses that purport to show that policies to reduce emissions of climate-altering gases will have a devastating effect on jobs and the overall economy.”

Without doubt those telling others that there is no danger heading their way have a special moral responsibility to be extraordinarily careful about such claims. For instance, if someone tells a child laying on a railroad tracks that they can lie there all day because there is no train coming and has never checked to see if a train is actually coming would be obviously guilty of reprehensible behavior.

Disinformation about the state of climate change science is extraordinarily if not criminally irresponsible because the consensus scientific view of climate change is based upon strong evidence that climate change harms:

(1) are already being experienced by tens of thousands in the world;(2) will be experienced in the future by millions of people from greenhouse gas emissions that have already been emitted but not yet felt due to lags in the climate system; and,

(3) will increase dramatically in the future unless GHG emissions are dramatically reduced from existing global emissions levels.

These harms include deaths and harms from droughts, floods, heat, storm related damages, rising oceans, heat impacts on agriculture, loss of animals that are dependent upon for substance purposes, social disputes caused by diminishing resources, sickness from a variety of diseases, the inability to rely upon traditional sources of food, the inability to use property that people depend upon to conduct their life including houses or sleds in cold places, the destruction of water supplies, and the inability to live where has lived to sustain life. In fact, the very existence of some small island nations is threatened by climate change. …

The October 21 New York Times article … concludes that some US corporate sponsored activities are helping elect politicians that have been influenced by the most irresponsible climate change scientific skeptical arguments. These corporations are clearly doing this because they see climate change greenhouse gas emissions reduction strategies as adversely affecting their financial interests. This fact leads to even greater moral culpability for American corporations because their behavior is as offensive as if the person who tells the child train that no train is coming when they don’t actually know whether a train is on its way makes money by misinforming the child.

The October 21 New York Times article concludes that the oil, coal and utility industries have collectively spent $500 million just since the beginning of 2009 to lobby against legislation to address climate change and to defeat candidates who support actions to reduce the threat of climate change. It would be one thing for an American corporation to act irresponsibly in a way that leads to harm to Americans, but because of climate change’s global scope, American corporation’s have been involved in behavior that likely will harm tens of millions of people around the world. Clearly this is a new type of crime against humanity. Skepticism in science is not bad, but skeptics must play by the rules of science including publishing their conclusions in peer-reviewed scientific journals and not make claims that are not substantiated by the peer-reviewed literature. The need for responsible skepticism is particularly urgent if misinformation from skeptics could lead to great harm. For this reason, this disinformation campaign being funded by some American corporations is some kind of new crime against humanity.

Corals and reality of climate change

Simon Donner writes on Maribo about climate change and coral reefs:

In 2007, my colleagues and I published a study examining of the likelihood of the 2005 “hot spot” occurring with and without human influence on the climate system. The study contrasted model simulations of the Caribbean with historical data and then computed the statistics of extreme ocean temperature events. The second slide summarizes some of the key results of from study. In a nutshell, our best analysis concluded the 2005 Caribbean “heat wave” would likely be on the order of a once in a thousand year event, had there been no human-generated greenhouse gas or aerosol emissions since the Industrial Revolution (“natural forcing”). By the 1990s, the human forcings increased the odds to once in 10-50 years. And continued warming under “business as usual” would make such heat waves happen in three out of every four years.

Five years later, a Caribbean “heat wave” has happened again. I’ve been writing for months that there was a strong likelihood of extensive coral bleaching in the Caribbean this fall according to NOAA’s advance forecast of sea surface temperatures (in fact, we had a good inkling of this last summer). Now we’re getting reports of bleaching from observers in the Caribbean. Add this to the observations (following predictions, once again!) from Southeast Asia and the Equatorial Pacific, and we have what may be the most, or second most, extensive “global” coral bleaching event in recorded history.

For all those writing about this event, keep in mind the predictions. This is what the scientific community predicted was likely to happen. An event which we calculated would be a once in a millennium occurrence without human impact on the climate, happened again five years later.

Phd and Postdoc funding on marine protected areas

Helen Fox of WWF writes to tell me that:

WWF is offering Fuller Fellowships to support doctoral and postdoctoral marine protected areas (MPA) research in our marine priority geographies that shows promise to enhance scientific understanding of their ecological and social impacts.

She is also co-organizing a 1-day symposium New Perspectives on MPA Performance:
Linking Knowledge to Action
on November 5 which will be webcast.
