This graphic, from Skeptical Science, is just awesome. I spend a good bit of my time thinking about climate change and its impacts on the global poor – mostly how we might address both global poverty and climate change, maximizing synergies and minimizing trade-offs between these efforts. I’ve been a lead author of two major global environmental assessments (the Millennium Ecosystem Assessment and GEO-4) and I am now a review author of the IPCC’s AR5. Despite all of this, I find that people still question my understanding of climate change – they want me to be deluded by false data, or somehow motivated by another political agenda that I can only accomplish through an environmental hoax. In short, they want me to be either stupid or a liar. Not that anyone will say that to my face, of course, but that is really what it boils down to.
So, I greatly appreciate when someone comes up with a means of communicating what we know about the changing climate that is both simple and clear. In one post, Skeptical Science has managed this. Everyone should take a look and have a quick read. First, the graphic:
Second, the explanation of the graphic:
1) If greenhouse warming is taking place, the stratosphere should cool while the troposphere warms (heat is being trapped in the troposphere). Check.
2) If greenhouse warming is taking place, nights should warm faster than days, as the nighttime radiation of heat into space will be limited by the greenhouse effect. Check.
3) For similar reasons, if greenhouse warming is taking place, winters should warm faster than summers. Check.
4) If greenhouse warming is taking place, and #1 is true, the troposphere/stratosphere boundary should rise as the warmer troposphere expands relative to the stratosphere. Check.
5) If greenhouse warming is taking place, out of the total carbon we find in the atmosphere, a rising percentage will be fossil carbon. There is really only one way for a lot of fossil carbon into the atmosphere, and that is burning fossil fuels (remember, oil, natural gas and coal come from the decomposition of long-dead animals). Check.
6) If greenhouse warming is taking place, the oceans should be warming up overall, not shifting heat around. Check.
In short, every theoretical predictor of the greenhouse effect is being realized in empirical measurement – again, not models, but the actual instrument record. So, unless folks are willing to argue that all thermometers, weather satellites, weather balloons, and tools for measuring atmospheric chemistry are wrong or somehow perverted to a hoax, there is no empirical basis to argue that greenhouse warming is not taking place – nor is there much of an argument to be made, given the rising presence of fossil carbon in the atmosphere, that humans have nothing to do with it . . .
Time to start dealing with reality, instead of denying it. What is happening in the global climate is affecting how we do development – or at least it should be. Changes in the global climate have manifest in various environmental shifts that in turn are impacting livelihoods, migration decisions, and the food security of the global poor. I’ll address this in a subsequent post . . .

Remedies for the Horn of Africa Famine? Delivering Development…differently
A number of folks have contacted me asking for a post that discusses how we might address the rapidly worsening famine in the Horn of Africa. In short, folks want to know what is being done, and what they can do, both in terms of the immediate famine and to prevent this from happening again.
First, in addressing the acute situation right now: please understand that aid agencies are moving as fast as they possibly can where they possibly can. There are a lot of challenges in southern Somalia, and these political-logistical hurdles matter greatly because the only remedy for the immediate situation is massive relief efforts to address the acute food insecurity in the area. There are complex logistics behind where those supplies might come from. That said, agencies are already moving to preposition aid materials as best they can.
If you want to help with the immediate relief effort, send money. Yes, money. Don’t send clothes, shoes, or any other stuff. It’s hard and expensive to deliver, and usually the donation of material goods just screws up local economies, making recovery from the crisis much harder and prolonged. Look into the groups, such as the Red Cross and the World Food Program, that are on the ground delivering aid. Examine their philosophies and programs, and donate to those you can agree with. There is a world of advice on donating to aid organizations out there on the blogs and twitter, so do a little research before donating. Oh, and please, please stay the hell out of the Horn of Africa, as you’ll just get in the way of highly trained, experienced people who are working under enough strain. I will make an exception for those with experience in emergency relief work – feel free to work through your networks to see if you are needed. If you don’t have a network to work through, you shouldn’t be going. It’s really that simple.
The question of how we will prevent the next famine is an open one. In my personal opinion (which, incidentally, counts for exactly nothing right now), addressing the causes of this famine, and the continuing sources of insecurity in this region, are going to require a rather different approach to development than that we have taken to this point. In my book (Delivering Development – hence the title of the post) I argue that part of the reason that development programs don’t end up solving the challenges that lead to things like famine is because we fundamentally misunderstand how development and globalization work. We are going to have to step back and move beyond technical fixes to particular challenges, and start to think about development as a catalyst for change. This means thinking broadly about what changes we want to see in the region, and how our resources might be used to initiate processes that bring those changes about. As I keep telling my students, there is no such thing as a purely technical, apolitical development intervention. Even putting a borehole in a village invokes local politics – who gathered the water before? Who gathers it now? Who can access the borehole, and who cannot? If the borehole has resulted in the creation of free time for whoever is responsible for water collection, what do they do with that free time? The answers to these questions and dozens of others will vary from place to place, but they shape the outcome of that borehole.
At the same time, such a process requires redefining the “we” in the sentence “thinking broadly about what changes we want to see in the region . . .,” because it really doesn’t matter what people, living in the United States or anywhere else outside the Horn of Africa, want to see in the region. It’s not their region. Instead, this “we” is going to have to emerge from a real partnership between those who live in the Horn of Africa, their governments, and the aid agencies with the resources to make particular programs and projects happen. For example, we are going to have to use our considerable science and technology capacity to really explore the potential of mobile communications as a source of rapidly-updated, geolocatable information about conditions on the ground to which people are responding with their livelihoods strategies. However, this technology and data will only be useful if it is interpreted into programs in concert with the sources of that data: people who are already managing tremendous challenges with few resources. Information about rainfall is just a data point, until we place it into social context – whose crops are most impacted by the absence/overabundance of water? Whose boreholes will dry up first? Whose cattle will be the first to die off? You can see how even changes in rainfall are nothing more than catalysts for local social process, as the answers to these latter questions will vary dramatically, but in the context of trying to understand how things will play out, they are far, far more important than simple biophysical measures of the environment (or quantitative analyses of the economy, for that matter).
In other words, I think that any effort to really address the next famine before it happens is going to be long and extraordinarily involved – and is going to require the help of agencies, implementing partners, academics, affected governments, and the people on the ground living through these challenges. It sounds utopian . . . but it is not. It is necessary. To end up doing the Horn of Africa famine dance again in a few years for lack of ambition, or because of an unwillingness to take a hard look at how we think about development and how it does not work, is an outcome I cannot accept. We will be judged by history for how we respond (if you have doubts, feel free to read Davis’ Late Victorian Holocausts and look at how the British come off).
Drought does not equal famine
After reading a lot of news and blog posts on the situation in the Horn of Africa, I feel the need to make something clear: the drought in the Horn of Africa is not the cause of the famine we are seeing take shape in southern Somalia. We are being pounded by a narrative of this famine that more or less points to the failure of seasonal rains as its cause . . . which I see as a horrible abdication of responsibility for the human causes of this tragedy.
First, I recommend that anyone interested in this situation – or indeed in food security and famine more generally, to read Mike Davis’ book Late Victorian Holocausts. It is a very readable account of massive famines in the Victorian era that lays out the necessary intersection of weather, markets and politics to create tragedy – and also makes clear the point that rainfall alone is poorly correlated to famine. For those who want a deeper dive, have a look at the lit review (pages 15-18) of my article “Postmodern Conceptualizations, Modernist Applications: Rethinking the Role of Society in Food Security” to get a sense of where we are in contemporary thinking on food security. The long and short of it is that food insecurity is rarely about absolute supplies of food – mostly it is about access and entitlements to existing food supplies. The HoA situation does actually invoke outright scarcity, but that scarcity can be traced not just to weather – it is also about access to local and regional markets (weak at best) and politics/the state (Somalia lacks a sovereign state, and the patchy, ad hoc governance provided by al Shabaab does little to ensure either access or entitlement to food and livelihoods for the population).
For those who doubt this, look at the FEWS NET maps I put in previous posts (here and here). Famine stops at the Somali border. I assure you this is not a political manipulation of the data – it is the data we have. Basically, the people without a functional state and collapsing markets are being hit much harder than their counterparts in Ethiopia and Kenya, even though everyone is affected by the same bad rains, and the livelihoods of those in Somalia are not all that different than those across the borders in Ethiopia and Kenya. Rainfall is not the controlling variable for this differential outcome, because rainfall is not really variable across these borders where Ethiopia, Kenya and Somalia meet.
This is not to say that rainfall doesn’t matter – it certainly does. But it is not the most important thing. However, when we focus on rainfall variability exclusively, we end up in discussions and arguments that detract from understanding what went wrong here, and what we might do going forward. Yes, the drought reflects a climate extreme . . . but this extreme is not that stunningly anomalous in this part of the world – we are getting similar (but not quite as bad) results quite often these days. Indeed, these results seem to be coming more frequently, and appear to be tied to a shift in the climate of the region – and while it is a bit soon to say this definitively, this climate shift is very likely is a product of anthropogenic climate change. So, one could indirectly argue that the climate change (mostly driven by big emitters in the Global North) is having a terrible impact on the poorest and weakest in the Global South. It will take a while to make this a firm argument, though.
On the other hand, it is clear that politics and markets have failed the people of Somalia – and the rainfall just pushed a very bad situation over the precipice into crisis. Thus, this is a human crisis first and foremost, whatever you think of anthropogenic climate change. Politics and markets are human inventions, and the decisions that drive them are also human. We can’t blame this famine on the weather – we need to be looking at everything from local and national politics that shape access and entitlements to food to global food markets that have driven the price of needed staples up across the world, thus curtailing access for the poorest. The bad news: Humans caused this. The good news: If we caused it, we can prevent the next one.
Finally saying Famine
As of 10am Nairobi time today, the United States Government, along with the UN, is acknowledging the presence of famine in southern Somalia. This is the first declaration of famine in twenty-odd years, reflecting the fairly high bar for human suffering that has to be crossed before an official declaration can be made.
The declaration is complex. The full text of the Famine Early Warning System Network (FEWS-NET) statement is here. But to summarize:
- a famine is currently ongoing in two areas of southern Somalia: the Bakool agropastoral livelihood zones and all areas of Lower Shabelle
- A humanitarian emergency currently exists across all other regions of the south, and current humanitarian response is inadequate to meet emergency needs. As a result, famine is expected to spread across all regions of the south in the coming 1‐2 months
- FEWS-NET estimates 3.7 million people are in crisis nationwide; among these 3.2 million people need immediate, lifesaving assistance (2.8 million in the south).
- FEWS-NET projections suggest that assistance needs will remain extremely high through at least December 2011
I think it is important to review what the currently understood conditions on the ground are right now:
- The crude death rate (simple measure of the number of deaths) has surpassed 2/10,000/day in two areas (Bakool agropastoral, and all of Lower Shabelle).
- The under 5 death rate has surpassed 4/10,000/day in all areas of the south where data is available, peaking at 20/10,000/day in Riverine areas of Lower Shabelle. These numbers are horrific.
- The prevalence of global acute malnutrition (GAM) exceeds 38 percent in 9 of the 11 areas where recent survey data is available – we consider 15% to be an emergency threshold. Severe acute malnutrition (SAM) exceeds 14 percent in these areas – and the emergency threshold here is 2-4%.
The projections going forward are not pretty. If, as FEWS-NET projects, we have famine conditions in play across all of Southern Somalia, historical death rates suggest we could be talking about mortality rates somewhere in the range of 2500 deaths a day at some point in August (though this is a high estimate, and a minimum number would be more in line with 700 deaths a day). I have no idea what percentage of these deaths will be children, but given the extremely elevated under-5 death rates (2X to 10X the global crude death rate), we can assume that the answer is “a hell of a lot.”
The causes of the famine are complex, and FEWS NET reviews them in the link above.
We are trying – and we are all frustrated at how slowly our response is moving. FEWS-NET’s efforts have been herculean, from data collection (see the picture below) to the organization of reports and data – I am seeing emails from these guys at 3am. I was impressed with them before I got here. I am even more impressed with them now. FEWS is just one part of the equation, though. There are a lot of people who are not sleeping right now, and even more who have dropped everything else they are doing to support this effort. We are trying.

Willful misdirection (or, more mendacious crap)
Pat Michaels has a rather astonishing blog called Climate of Fear at Forbes.com. Too bad for Forbes – they are providing a platform for a serious climate crank who I think is far too well-educated and smart to misunderstand the things he misrepresents in his public statements and writing. His recent post on climate change and food security is a classic of the genre – and fits very well into the strategies that Naomi Oreskes and Erik Conway so brilliantly lay out in Merchants of Doubt (which, if you want to understand the professional climate change denial camp, you absolutely must read). It requires debunking. Hell, the man’s blog requires debunking, post by post.
So, what does Michaels have to say about climate change and food security? Well, in a nutshell he doesn’t see how climate change is a problem for agriculture – indeed, he seems to suggest that climate change will do good things for agriculture. However, a careful read of the article for what it does and does not actually say, and what evidence it draws on (mostly tangential), demonstrates that this is a piece of misdirection that, in my opinion, is criminal: insofar as it causes anyone to doubt the severity of the challenge in front of us, it will cost lives. Lots of lives.
Michaels begins with a classic of the denial genre – he goes after a New York Times article not on its merits (indeed, he never addresses any of the article’s content), but by lumping it in with every previous warning of what he calls “environmental apocalypse.” Except, of course, that the only call he actually cites is the now legendary “global cooling” fear of the 1970s – a fringe belief that was never embraced by the majority of scientists (no matter how hard the denial crowd wants you to believe it). That concern was based on patterns of natural cycles of heating and cooling that some felt were timed to push us back toward another ice age, but it was not the consensus view of scientists at the time. Michaels knows this. Either that, or he was a very, very bad graduate student, as he claims to have recieved his doctorate on the wings of “global cooling.”
Then Michaels moves to a false correlation (or non-correlation) – temperatures rose by .75 degrees C over the 20th Century (about 1.35 degrees Farenheit), but Michaels argues that since “U.S. corn yields quintupled. Life expectancy doubled. People got fat” clearly there is nothing to worry about. Except, of course, that temperature/CO2 has relatively little to do with these results – biotech and improved farming techniques were much, much more important – and one could argue that these techniques and biotech have persevered in the face of conditions that might have, in many parts of the world, led to declining yields. Hell, it is well known that the increases in per-capita food availability worldwide are not evenly distributed – According to the Food and Agriculture Organization of the United Nations (FAO), in sub-Saharan Africa there is less food per person than there was thirty years ago. Either Michaels has a distressingly flawed understanding of correlation and no real understanding of agricultural development over the past 100 years, or he is willfully misdirecting the reader. Either case should disqualify him from writing this article.
Besides, temperature is only one concern (it is possible that some parts of the globe will warm several degrees Celsius, pushing some current staple crops out of the temperature bands in which they can germinate) – Michaels makes no mention of precipitation, except to basically trot out the old “CO2 is plant food” argument by saying “greenhouse warming takes place more in the winter, which lengthens growing seasons. With adequate water, plants then fix and yield more carbohydrate.” This is almost hilarious, as one of the biggest problems we face is finding adequate water. Rising atmospheric temperatures have driven changes in wind patterns and atmospheric moisture content which, in turn, have shifted rainfall patterns over the past century or more. Today CO2 is not able to serve as plant food in many parts of the world that most need it because the very injection of more CO2 into the atmosphere is creating declines in the rain needed to make that CO2 useful to plants. Unless Michaels is willing to argue that rainfall patterns have not shifted, and therefore is willing to ignore rain gauge data from around the world, he has just offered the reader another misleading argument.
To address these empirically-documented challenges, farmers have adopted new crops, some biotech and improved irrigation tech has helped (though in parts of sub-Saharan Africa, a region in which most agriculture is rain-fed, farmers are getting hammered by precipitation change) , but we are moving into an era where the vast bulk of work on GMOs is “defensive” – that is, trying to hold the line on yields as environmental conditions deteriorate. This is not a recipe for continued rising yields in the future – which makes a few of his later claims really, really embarrassing – if he had shame, that is. His claim that the continued increase in per capita grain production is going up means that climate change has had no effect is a logical fallacy – he is not factoring in how much production we have lost because of climate effects (and we are losing production – Southern Africa is one example). His claims about rising wheat production in the future, even in a world free of wheat rust, presume either current environmental conditions will hold or that there will be significant technological advances that boost yields – but these are assumptions, not facts that can be stated with certainty.
In short, Michael’s alignment of temperature change and improving human conditions are basically unrelated . . . unless one wants to (rightly) note that many of the things that allowed us to live longer and get fatter required manufacturing processes and transport mechanisms that burned fossil fuels, thus warming the atmosphere – in other words, causality runs the other way. We live longer and better, which is in part causing the warming of the atmosphere. But Michaels can’t even consider that direction of causality . . .
I do agree with Michaels that using food crops for ethanol is and was stupid. Of course, I was saying this (along with a lot of other colleagues) at author meetings of UNEP’s Fourth Global Environment Outlook in 2005. The decision to push biofuels was political, not scientific. Welcome to the party, Pat – we’ve already been here for a while, but there might still be some beer in the keg . . .
So, to summarize – Michaels has created a post that relies on false correlation, logical fallacy and misdirection to create the idea that climate change might not be a problem for agriculture, and that it might even be good for global production. But he does not cite the vast bulk of the science out there – and ignores the empirical literature (not theory, not conjecture – measured changes) to create a very deceptive picture that minimizes the slowly intensifying challenges facing people living in many parts of the Global South. I invite Dr. Michaels to look at the FEWS-NET data – not just contemporary, but historical – on the East African/Horn of Africa climate. Empirical observation (again, measured, verified observations, not projections) tells us it is drying out* . . . and has been, for some time, massively compromising both crops and livestock, the backbone of livelihoods in Southern Ethiopia, Somalia and Northeastern Kenya. As all hell breaks loose in that region, and the US Government considers using the term famine for the first time in a decade to describe the situation on the ground, it seems to me that Michaels’ efforts at misdirection rise beyond nuisance to a real question of ethics that Forbes would do well to consider before publishing such mendacious material again.
*very important note: FEWS-NET is agnostic as to the causes of the drying out – at this time, they do not care what causes it, they need to document it to better organize US Government and multilateral food aid delivery. They would have jobs even if climate change did not exist, as the weather does vary from year to year no matter what, and therefore food insecurity would vary year by year.
Oh, so you CAN say it out loud
The AP is running a story on food prices – and it is heavily focused on the problem of commodities speculation. Actually, it is heavily focused on French President Nicholas Sarkozy’s comments on the causes of the food price increases. While Sarkozy acknowledged the importance of issues like climate change, he quickly moved past these causes:
Sarkozy said the difficulties go far beyond the whims of nature. He said financial market specialists — instead of agricultural trading houses — had taken over the global farm market and called for change.
“Take the Chicago market,” said Sarkozy, listing how the derivatives exchange totals 46 times the annual U.S. wheat production and 24 times that of corn. He said 85 percent of the contracts on commodities futures markets are held by purely financial players “with no link to the commodity itself.”
“The example shows to what extent our world has lost a sense of value, a sense of reality, a sense of capitalism to serve the development and happiness of people,” Sarkozy said.
It is worth noting that Sarkozy is no leftist . . . though he will likely be painted as one for that last sentence. Then again, anyone who notes that markets might have negative as well as positive effects will be painted as anti-capitalist/naive/out-of-place ideologue (see the comments on Dot Earth’s mention of my concerns over climate change communication).
Let me note that Sarkozy is not demonizing all speculation – nor do I. As I discussed in an earlier post, speculation plays an important economic role that can distribute the stresses that lead to future price spikes over time, thus ameliorating future crisis. However, this is not to say that speculation should just run unregulated – basic regulation that keeps speculation within productive parameters would likely enhance its value in the food security arena. (See this IFPRI forum for more on the role of speculation in world food markets)
However, more information for these markets would probably help as well. While the USDA and other organizations offer estimates of global and sometimes national-level agricultural production, it would be good to have concrete, sub-national datasets on ag production updated in real time – this would remove some of the uncertainty in commodities markets that can then be leveraged into arbitragable price instability . . . and that alone might start to clean out the more problematic players in agricultural commodities markets.
And now everyone is implicated . . .
Updated 7 June 2011: I can find no evidence that any of my TIAA-CREF funds are holding Glencore. So far, so good . . .
aaannnnddd
No Glencore in my Vanguard 2025 Fund (kid’s college fund). Sadly, though, there is Gazprom. And probably a hell of a lot of other problematic stuff . . . nobody is clean, I tell you.
As a geographer, I spend a lot of time thinking about interconnections – how events and processes in one place influence events and processes in other places. I use these interconnections as a teaching tool in my courses, to help students understand how, for example, our levels of consumption here in the US preclude similar levels of consumption for the rest of the world (not enough resource out there to make that happen). I am always careful to make sure that the students understand that I am as bound up in these linkages as they are – I certainly do not live off the grid, walking/riding a bike everywhere and eating only food I grow (or that is grown locally). But it still hurts every time a find a new way in which I am bound to, and therefore a cause of, some of the processes I find most frustrating in the world. So, this excellent post on FairPensions was a bit tough. Simply put, Glencore, a well-known problem company that trades heavily in the food commodities markets (and appears to be making those markets, as it were, to its own advantage) has been fast-tracked into the FTSE 100, and therefore is now likely part of a lot of the mutual funds and pension plans to which we all make contributions. I’m going to have to check on this, and pray that TIAA-CREF has some sense, but . . . dammit.
For an earlier discussions of food insecurity and the commodities markets, see here, here and here.
I'm a talking head . . .
Geoff Dabelko, Sean Peoples, Schuyler Null and the rest of the good folks at the Environmental Change and Security Program at the Woodrow Wilson Center for Scholars were kind enough to interview me about some of the themes in Delivering Development. They’ve posted the video on te ECSP’s blog, The New Security Beat (you really should be checking them out regularly). So, if you want to see/hear me (as opposed to read me), you can go over to their blog, or just click below.
Qualitative research was (already) here . . .
You know, qualitative social scientists of various stripes have long complained of their marginalization in development. Examples abound of anthropologists, geographers, and sociologists complaining about the influence of the quantitatively-driven economists (and to a lesser extent, some political scientists) over development theory and policy. While I am not much for whining, these complaints are often on the mark – quantitative data (of the sort employed by economists, and currently all the rage in political science) tends to carry the day over qualitative data, and the nuanced lessons of ethnographic research are dismissed as unimplementable, ideosyncratic/place-specific, without general value, etc. This is not to say that I have an issue with quantitative data – I believe we should employ the right tool for the job at hand. Sadly, most people only have either qualitative or quantitative skills, making the selection of appropriate tools pretty difficult . . .
But what is interesting, of late, is what appears to be a turn toward the lessons of the qualitative social sciences in development . . . only without actually referencing or reading those qualitative literatures. Indeed, the former quantitative masters of the development universe are now starting to figure out and explore . . . the very things that the qualitative community has known for decades. What is really frustrating and galling is that these “new” studies are being lauded as groundbreaking and getting great play in the development world, despite the fact they are reinventing the qualitative wheel, and without much of the nuance of the current qualitative literature and its several decades of nuance.
What brings me to today’s post is the new piece on hunger in Foreign Policy by Abhijit Banerjee and Esther Duflo. On one hand, this is great news – good to see development rising to the fore in an outlet like Foreign Policy. I also largely agree with their conclusions – that the poverty trap/governance debate in development is oversimplified, that food security outcomes are not explicable through a single theory, etc. On the other hand, from the perspective of a qualitative researcher looking at development, there is nothing new in this article. Indeed, the implicit premise of the article is galling: When they argue that to address poverty, “In practical terms, that meant we’d have to start understanding how the poor really live their lives,” the implication is that nobody has been doing this. But what of the tens of thousands of anthropologists, geographers and sociologists (as well as representatives of other cool, hybridized fields like new cultural historians and ethnoarchaeologists). Hell, what of the Peace Corps?
Whether intentional or not, this article wipes the qualitative research slate clean, allowing the authors to present their work in a methodological and intellectual vacuum. This is the first of my problems with this article – not so much with its findings, but with its appearance of method. While I am sure that there is more to their research than presented in the article, the way their piece is structured, the case studies look like evidence/data for a new framing of food security. They are not – they are illustrations of the larger conceptual points that Banerjee and Duflo are making. I am sure that Banerjee and Duflo know this, but the reader does not – instead, most readers will think this represents some sort of qualitative research, or a mixed method approach that takes “hard numbers” and mixes it in with the loose suppositions that Banerjee and Duflo offer by way of explanation for the “surprising” outcomes they present. But loose supposition is not qualitative research – at best, it is journalism. Bad journalism. My work, and the work of many, many colleagues, is based on rigorous methods of observation and analysis that produce validatable data on social phenomena. The work that led to Delivering Development and many of my refereed publications took nearly two years of on-the-ground observation and interviewing, including follow-ups, focus groups and even the use of archaeology and remotely-sensed data on land use to cross-check and validate both my data and my analyses.
The result of all that work was a deep humility in the face of the challenges that those living in places like Coastal Ghana or Southern Malawi manage on a day-to-day basis . . . and deep humility when addressing the idea of explanation. This is an experience I share with countless colleagues who have spent a lot of time on the ground in communities, ministries and aid organizations, a coming to grips with the fact that massively generalizable solutions simply don’t exist in the way we want them to, and that singular interventions will never address the challenges facing those living in the Global South.
So, I find it frustrating when Banerjee and Duflo present this observation as in any way unique:
What we’ve found is that the story of hunger, and of poverty more broadly, is far more complex than any one statistic or grand theory; it is a world where those without enough to eat may save up to buy a TV instead, where more money doesn’t necessarily translate into more food, and where making rice cheaper can sometimes even lead people to buy less rice.
For anyone working in food security – that is, anyone who has been reading the literature coming out of anthropology, geography, sociology, and even some areas of ag econ, this is not a revelation – this is standard knowledge. A few years ago I spent a lot of time and ink on an article in Food Policy that tried to loosely frame a schematic of local decision-making that leads to food security outcomes – an effort to systematize an approach to the highly complex sets of processes and decisions that produce hunger in particular places because there is really no way to get a single, generalized statistic or finding that will explain hunger outcomes everywhere.
In other words: We know. So what do you have to tell us?
The answer, unfortunately, is not very much . . . because in the end they don’t really dive into the social processes that lead to the sorts of decisions that they see as interesting or counterintuitive. This is where the heat is in development research – there are a few of us working down at this level, trying to come up with new framings of social process that move us past a reliance solely on the blunt tool of economistic rationality (which can help explain some behaviors and decisions) toward a more nuanced framing of how those rationalities are constructed by, and mobilize, much larger social processes like gender identification. The theories in which we are dealing are very complex, but they do work (at least I think my work with governmentality is working – but the reviewers at Development and Change might not agree).
And maybe, just maybe, there is an opening to get this sort of work out into the mainstream, to get it applied – we’re going to try to do this at work, pulling together resources and interests across two Bureaus and three offices to see if a reframing of livelihoods around Foucault’s idea of governmentality can, in fact, get us better resolution on livelihoods and food security outcomes than current livelihoods models (which mostly assume that decisionmaking is driven by an effort to maximize material returns on investment and effort). Perhaps I rest too much faith on the idea of evidence, but if we can implement this idea and demonstrate that it works better, perhaps we will have a lever with which to push oversimplified economistic assumptions out of the way, while still doing justice to the complexity of social process and explanation in development.
On Math, Climate Change and Food Security
Idiot Tracker has a post on food security that uses food security as a means of focusing the reader on the challenges that climate change are likely to present in the near future. In short, the argument goes that climate change will negatively impact our future agricultural productivity, making it difficult to increase that productivity as our population grows. If we do hit nine billion people by mid-century (barring cataclysm this seems to be the minimum number we will hit), the author calculates that we will need to come up with 14.5 trillion calories per day, and notes that climate change is likely to present significant barriers to meeting this need.
I agree . . . in a general way. We are losing huge amounts of arable land each year to soil degradation, and we are running out of productive places in which to extend new farms that do not create really problematic ecological tradeoffs (like massive deforestation that speeds climate change). Climate change is likely to force the transformation of entire agricultural regimes in otherwise sustainable areas – for example, by changing temperatures and precipitation such that most strains of maize will have difficulty germinating in Southern Africa in a few decades. This is all a very big deal. But this post is also very, very thin on support for its argument.
As the post does not present any hard data, including how the 14.5 trillion calorie per day figure was derived, I cannot be sure if the author did any real math on our current production or the likely loss of caloric production that might occur under any number of likely climate scenarios (a problem unto itself, at global circulation models are much better for temperature than they are for rainfall, and there are few regional circulation models that can correct this problem – see the fascinating recent work of FEWS-NET on modeled versus empirically-measured patterns of precipitation in East Africa). All of these might create significant error bars around likely future caloric production. Further, I cannot tell if the author has considered whether or not crops will migrate as their ecological zones shift – surely farmers that previously could not raise a certain crop will start to take it up as the local environment allows and as other producing areas fall out of favor. We know that some ecosystems will at least start to migrate if corridors for such movement are available – and agricultural systems are just another form of (heavily managed) ecosystem. As cropping areas shift, what will the net caloric impact be? It is not enough to say that we will lose a lot of calories when maize stops germinating in southern Africa. We will need to get a net figure by calculating in all of the new areas in which maize will germinate.
Of course, such math only works at the global scale, and issues of hunger have very little to do with global production – hunger is local, shaped more by the intersection of markets, the environment, politics and society. So noting that maize will germinate in new areas does nothing for the people in southern Africa who will be without maize. However, we have to obtain another net figure: the lost calories from maize versus the new calories from new crops that people can grow, but chose not to before. This may still total a net decrease in calories (indeed, it probably will), but this is not the same as simply subtracting maize from the equation.
Finally, what of plants that are edible, but that we currently choose not to eat? The clearest analogy, to me, is the evolution of seafood here in the US. I like to explain to my students that these new, exotic fish that are showing up at restaurants are the species that no self-respecting chef would touch two decades ago. But when you wipe out the cod, you start getting creative. And don’t get me started about tilapia. It’s the rat of fish. Seriously, it likes murky, stagnant water. It will grow anywhere. There is nothing I find funnier than hearing a server say “we have a very nice tilapia today.” Yeah, I’d love to pay $20 for the swimming pigeon, thanks! That said, people do eat tilapia and all sorts of other hilarious species because they are hungry and willing to pay. So what new species of plant and animal will we be willing to eat a decade from now? Three decades from now? This is hard to predict, but I’ll bet quite a lot that we will find new species to exploit and offset even more of this caloric loss.
Despite all of this, I do think we face significant food challenges in the next three to four decades. These will be felt very unevenly around the world, but they will be felt in significant ways. To figure out what these impacts will look like, and who will experience them, requires that we carefully think through not only the exposure of crops to climate change impacts, but also the sensitivity and adaptive capacity of the agroecological system to those impacts. It is only when we understand how such systems are likely to respond that we can begin to really plan for the challenges ahead.
