On livelihoods and global environmental change

In a comment on my earlier post critiquing the recent ENSO and conflict piece that appeared in nature Nature , Joe pointed out that my argument that the authors of the piece did not understand livelihoods was not necessarily clear to the reader.  I think this is completely fair – I am buried in livelihoods . . . it is a concept at the core of what I have researched for the past 14 years, and therefore what may seem obvious to me is not so obvious to everyone else.
First, to clarify: I think the top-line issue I was shorthanding in my response to Solomon was the causal framework: it is totally unclear to me how they think environmental change is translated into conflict.  It is possible that they had no explicit notion of how this connection is made, but I think that would create an enormous set of problems for the study as it would make it impossible to know what variables to control for in the study (to some extent, I think this is a problem with the study anyway).  However, the study, and Solomon’s response, led me to believe that they did have a very basic framing of this connection, where weather impacts livelihoods which impacts behavior.  In this apparent framing, it seems to me that they treated livelihoods as a straightforward set of activities – and the impact of weather on those activities could be easily and generally understood, and the human outcomes of those impacts could also be easily and generally understood.  If this is true, it is a serious misunderstanding of livelihoods.
There is a lot of stuff I could say about livelihoods – my current intellectual project involves rethinking how we understand livelihoods, because I think current analytical frameworks cannot really engage with actual livelihoods decision-making on the ground.  As a result, a lot of our understandings of what people do, and why they do it, are wide of the mark, and the interventions we design to improve/augment/replace existing means of making a living in particular places are often misguided and prone to “surprise” outcomes.
First, a quick definition of livelihoods as they are treated in the contemporary literature: “the capabilities, assets (stores, resources, claims and access) and activities required for a means of living” (Chambers and Conway, 1992:7).  As Brent McCusker and I have argued:

this definition of livelihoods moves past income toward a more holistic consideration of the manner in which a person obtains a living. In practice, this definition has resulted in a number of approaches to livelihoods that focus closely on access to various types of assets drawn upon by individuals to make a living. These approaches tend to categorize these assets as one of five types of capital: natural, physical, human, financial and social. Land comes under natural capital, “the natural resource base (land, water, trees) that yields products utilized by human populations for their survival,” though an improved field might come under the heading of physical capital, which generally includes “assets brought into existence by economic production processes.”

My problem with the livelihoods approach that dominates the literature, and subtly undergirds the Nature piece I was critiquing, is not the broad definition of livelihoods.  Instead, the problem lies in the subtle assumption of this approach that, in its focus on the requirements for a means of living, concentrates on material circumstances and outcomes as a metric for the success and viability of particular livelihoods.  As I have demonstrated repeatedly (for example here, and in my book Delivering Development), livelihoods are double-edged: they are aimed at both meeting certain material requirements of life and maintaining the privileges of the powerful.  Above certain very, very low thresholds, the social goals of livelihoods actually trump the material goals.  Therefore, if we want to understand livelihoods decisions and outcomes, we must understand the social context at least as well as we do the material conditions in a particular place.  Using generalized assumptions about human motivations to explain responses to livelihoods shifts will smooth over really significant differences in decision-making, and therefore obscure any possible causal connection between things like environmental change and the incidence of conflict – material maximization/deprivation is only part of the story of human motivations, and a relatively small part at that.
How does this all relate to the Nature piece and my criticism? While the authors never specified the means by which this would happen in the piece, only offering general speculation in their response to my criticism, I found Solomon’s response to my blog post really telling:

The study is trying to understand whether choosing to engage in conflict is a “livelihood decision” that individuals in modern societies select more often when El Nino events occur. Our findings tells us that for some reason, people’s willingness to engage in organized violence changes when the global climate changes. One hypothesis is that perhaps “predation” (i.e. the forceful extraction of property from others) is a form of “adaptation” to climate changes.

It is possible that Solomon’s reference to conflict as a livelihoods decision was simply echoing the terms of my criticism.  However, both the article and his response seems to reflect an implicit framing of the environment-to-conflict connection as somehow passing through livelihoods in a straightforward manner.  Because the authors never actually unpack how the environment impacts livelihoods, and in turn how those impacts are translated into human impacts, they become guilty of the same issue that plagues nearly everyone using the livelihoods framework these days: they implicitly embrace an over-generalized framing of livelihoods decisions that relies too heavily on a relatively minor driver of decision-making (material conditions), and completely ignores the dominant factors that shape the character of particular activities and therefore result in particular outcomes for the well-being of those living under that strategy.  I am sure that predation does occur.  I am also absolutely certain that this is not a general response – it does not happen very often (plenty of empirical studies show other behaviors).  It is not interesting to know that it occurs – we already know that.  What is interesting and important is why it occurs.  Going for “story time” explanations of complex behavior does not contribute to our understanding of human behavior, or the impact of climate change on human well-being.
I am working on a reframing of livelihoods that elevates the social component to its proper place in livelihoods decision-making (in review at the Journal of Development Studies).  The thinking behind this reframing is intensely theoretical and really, really academic (for a taste of what I mean, see this piece I wrote with Brent).  My goal in the forthcoming piece is to take this really esoteric theory and turn it into an approach that can be understood and employed widely.  With any luck it will be accepted and published relatively soon . . . I will put up a pre-print as soon as I am able.  But even with this reframing, we are going to have to work really hard at understanding when large-scale studies such as the one I have been critiquing are appropriate for furthering our understanding of things we really need to know, when they merely illustrate what we already know, and when they present really problematic findings with a misleading level of certainty.

Why should the aid/relief/development community care about global environmental change (Pt. 4)?

So, how do we fix the way we think about development to address the challenges of global environmental change?  Well, there are myriad answers, but in this post I propose two – we have to find ways of evaluating the impact of our current projects such that those lessons are applicable to other projects that are implemented in different places and at various points in the future . . . and we have to better evaluate just where things will be in the future as we think about the desired outcomes of development interventions.
To achieve the first of these two is relatively easy, at least conceptually: we need to fully link up the RCT4D crowd with the qualitative research/social theory crowd.  We need teams of people that can bring the randomista obsession with sampling frames and serious statistical tools – in other words, a deep appreciation for rigor in data collection – and connect it to the qualitative social theoretical emphasis on understanding causality by interrogating underlying social process – in other words, a deep appreciation for rigor in data interpretation.  Such teams work to cover the weaknesses of their members, and could bring us new and very exciting insights into development interventions and social process.
Of course, everyone says we need mixed methodologies in development (and a lot of other fields of inquiry), but we rarely see projects that take this on in a serious way.  In part, this is because very few people are trained in mixed methods – they are either very good at qualitative methods and interpretation, or very good at sampling and quantitative data analysis.  Typically, when a team gets together with these different skills, one set of skills or the other predominates (in policy circles, quant wins every time).  To see truly mixed methodologies, this cannot happen – as soon as one trumps the other, the value of the mixing declines precipitously.
For example, you need qualitative researchers to frame the initial RCT – an RCT framed around implicit, unacknowledged assumptions about society is unlikely to “work” – or to capture the various ways in which an intervention works.  At the same time, the randomista skill of setting up a sampling frame and obtaining meaningful large-scale data sets requires attention to how one frames the question, and where the RCT is to be run . . . which impose important constraints on the otherwise unfettered framings of social process coming from the qualitative side, framings that might not really be testable in a manner that can be widely understood by the policy community.  Then you need to loop back to the qualitative folks to interpret the results of the initial RCT – to move past whether or not something worked to the consideration of the various ways in which it did and did not work, and a careful consideration of WHY it worked.  Finally, these interpretations can be framed and tested by the qualitative members of the team, starting an iterative interpretive process that blends qualitative and quantitative analysis and interpretation to rigorously deepen our understanding of how development works (or does not work).
The process I have just described will require teams of grownups with enough self-confidence to accept criticism and to revise their ideas and interpretations in the face of evidence of varying sorts.  As soon as one side of this mixed method team starts denigrating the other, or the concerns of one side start trumping those of the other, the value of this mixing drops off – qualitative team members become fig leaves for “story time” analyses, or quantitative researchers become fig leaves for weak sampling strategies or overreaching interpretations of the data.  This can be done, but it will require team leaders with special skill sets – with experience in both worlds, and respect for both types of research.  There are not many of these around, but they are around.
Where are these people now?  Well, interestingly the answer to this question leads me to the second answer for how development might better answer the challenges of global environmental change: development needs to better link itself with the global environmental change community.  Despite titles that might suggest otherwise (UNEP’s Fourth Global Environment Outlook was titled Environment for Development), there is relatively little interplay between these communities right now.  Sure, development folks say the right things about sustainability and climate change these days, but they are rarely engaging the community that has been addressing these and many other challenges for decades.  At the same time, the global environmental change community has a weak connection to development, making their claims about the future human impacts of things like climate change often wildly inaccurate, as they assume current conditions will persist into the future (or they assume equally unrealistic improvements in future human conditions).
Development needs to hang out with the scenario builders of the global environmental change community to better understand the world we are trying to influence twenty years hence – the spot to which we are delivering the pass, to take up a metaphor from an earlier post on this topic.  We need to get with the biophysical scientists who can tell us about the challenges and opportunities the expect to see two or more decades hence.  And we need to find the various teams that are already integrating biophysical scientists and social scientists to address these challenges – the leaders already have to speak quant and qual, science and humanities, to succeed at their current jobs.  The members of these teams have already started to learn to respect their colleagues’ skills, and to better explain what they know to colleagues who may not come at the world with the same framings, data or interpretations.  They are not perfect, by any stretch (I voice some of my concerns in Delivering Development), but they are great models to go on.
Meanwhile, several of my colleagues and I are working on training a new generation of interdisciplinary scholars with this skill set.  All of my current Ph.D. students have taken courses in qualitative methods, and have conducted qualitative fieldwork . . . but they also have taken courses on statistics and biogeographic modeling.  They will not be statisticians or modelers, but now they know what those tools can and cannot do – and therefore how they can engage with them.  The first of this crew are finishing their degrees soon . . . the future is now.  And that gives me reason to be realistically optimistic about things . . .

Why should the aid/relief/development community care about global environmental change (Pt. 3)?

OK, ok, you say: I get it, global environmental change matters to development/aid/relief.  But aside from thinking about project-specific intersections between the environment and development/aid/relief, what sort of overarching challenges does global environmental change pose to the development community?  Simply put, I think that the inevitability of various forms of environmental change (a level of climate change cannot be stopped now, certain fisheries are probably beyond recovery, etc.) over the next 50 or so years forces the field of development to start thinking very differently about the design and evaluation of policies, programs, and projects . . . and this, in turn, calls into question the value of things like randomized control trials for development.
In aid/development we tend to be oriented to relatively short funding windows in which we are supposed to accomplish particular tasks (which we measure through output indicators, like the number of judges trained) that, ideally, change the world in some constructive manner (outcome indicators, like a better-functioning judicial system).  Outputs are easier to deliver and measure than outcomes, and they tend to operate on much shorter timescales – which makes them perfect for end-of-project reporting even though they often bear little on the achievement of the desired outcomes that motivated the project in the first place (does training X judges actually result in a better functioning judicial system?  What if the judges were not the problem?).  While there is a serious push in the development community to move past outputs to outcomes (which I generally see as a very positive trend), I do not see a serious conversation about the different timescales on which these two sorts of indicators operate.  Outputs are very short-term.  Outcomes can take generations.  Obviously this presents significant practical challenges to those who do development work, and must justify their expenditures on an annual basis.
This has tremendous implications, I think, for development practice in the here and now – especially in development research.  For example, I think this pressure to move to outcomes but deliver them on the same timescale as outputs has contributed to the popularity of the randomized control trials for development (RCT4D) movement.  RCT4D work gathers data in a very rigorous manner, and subjects it to interesting forms of quantitative analysis to determine the impact of a particular intervention on a particular population.  As my colleague Marc Bellemare says, RCTs establish “whether something works, not how it works.”
The vast majority of RCT4D studies are conducted across a few months to years, directly after the project is implemented.  Thus, the results seem to move past outputs to impacts without forcing everyone to wait a very long time to see how things played out.  This, to me, is both a strength and a weakness of the approach . . . though I never hear anyone talking about it as a weakness.  The RCT4D approach seems to suggest that the evaluation of project outcomes can be effectively done almost immediately, without need for long-term follow-up.  This sense implicitly rests on the forms of interpretation and explanation that undergird the RCT4D approach – basically, what I see as an appallingly thin approach to the interpretation of otherwise interesting and rigorously gathered data. My sense of this interpretation is best captured by Andrew Gelman’s (quoting Fung) use of the term “story time”, which he defines as a “pivot from the quantitative finding to the speculative explanation.” It seems that many practitioners of RCT4D seem to think that story time is unavoidable . . . which to me reflects a deep ignorance of the concerns for rigor and validity that have existed in the qualitative research community for decades.  Feel free to check the methods section of any of my empirically-based articles (i.e. here and here): they address who I interviewed, why I interviewed them, how I developed interview questions, and how I knew that my sample size had grown large enough to feel confident that it was representative of the various phenomena I was trying to understand.  Toward the end of my most recent work in Ghana, I even ran focus groups where I offered my interpretations of what was going on back to various sets of community members, and worked with them to strengthen what I had right and correct what I had wrong.  As a result, I have what I believe is a rigorous, highly nuanced understanding of the social causes of the livelihoods decisions and outcomes that I can measure in various ways, qualitative and quantitative, but I do not have a “story time” moment in there.
The point here is that “story time”, as a form of explanation, rests on uncritical assumptions about the motivations for human behavior that can make particular decisions or behaviors appear intelligible but leave the door open for significant misinterpretations of events on the ground.  Further, the very framing of what “works” in the RCT4D approach is externally defined by the person doing the evaluation/designing the project, and is rarely revised in the face of field realities . . . principally because when a particular intervention does not achieve some externally-defined outcome, it is deemed “not to have worked.”  That really tends to shut down continued exploration of alternative outcomes that “worked” in perhaps unpredictable ways for unexpected beneficiaries.  In short, the RCT4D approach tends to reinforce the idea that development is really about delivering apolitical, technical interventions to people to address particular material needs.
The challenge global environmental change poses to the RCT4D randomista crowd is that of the “through ball” metaphor I raised in my previous post.  Simply put, identifying “what works” without rigorously establishing why it worked is broadly useful if you make two pretty gigantic assumptions: First, you have to assume that the causal factors that led to something “working” are aspects of universal biophysical and social processes that are translatable across contexts.  If this is not true, an RCT only gives you what works for a particular group of people in a particular place . . . which is not really that much more useful than just going and reading good qualitative ethnographies.  If RCTs are nothing more than highly quantified case studies, they suffer from the same problem as ethnography – they are hard to aggregate into anything meaningful at a broader scale.  And yes, there are really rigorous qualitative ethnographies out there . . .
Second, you have to assume that the current context of the trial is going to hold pretty much constant going forward.  Except, of course, global environmental change more or less chucks that idea for the entire planet.  In part, this is because global environmental change portends large, inevitable biophysical changes in the world.  Just because something works for improving rain-fed agricultural outputs today does not mean that the same intervention will work when the enabling environmental conditions, such as rainfall and temperature, change over the next few decades.  More importantly, though, these biophysical changes will play out in particular social contexts to create particular impacts on populations, who will in turn develop efforts to address those impacts. Simply put, when we introduce a new crop today and it is taken up and boosts yields, we know that it “worked” by the usual standards of agricultural development and extension.  But the take-up of new crops is not a function of agricultural ecology – there are many things that will grow in many places, but various social factors ranging from the historical (what crops were introduced via colonialism) to gender (who grows what crops and why) are what lead to particular farm compositions.  For example, while tree crops (oil palm, coconut, various citrus, acacia for charcoal) are common on farms around the villages in which I have worked in Ghana, almost none of these trees are found on women’s farms.  The reasons for this are complex, and link land tenure, gender roles, and household power relations into livelihoods strategies that balance material needs with social imperatives (for extended discussions, see here and here, or read my book).
Unless we know why that crop was taken up, we cannot understand if the conditions of success now will exist in the future . . . we cannot tell if what we are doing will have a durable impact.  Thus, under the most reliable current scenario for climate change in my Ghanaian research context, we might expect the gradual decline in annual precipitation, and the loss of the minor rainy season, to make tree crops (which tend to be quite resilient in the face of fluctuating precipitation) more and more attractive.  However, tree crops challenge the local communal land tenure system by taking land out of clan-level recirculation, and allowing women to plant them would further challenge land tenure by granting them direct control over access to land (which they currently lack).  Altering the land tenure system would, without question, set off a cascade of unpredictable social changes that would be seen in everything from gender roles to the composition of farms.  There is no way to be sure that any development intervention that is appropriate to the current context will be even functional in that future context.  Yet any intervention we put into place today should be helping to catalyze long-term changes . . .
Simply put: Global environmental change makes clear the limitations of our current thinking on aid/development (of which RCT4D is merely symptomatic).   Just like RCTs, our general framing of development does not move us any closer to understanding the long-term impact of our interventions.  Further, the results of RCTs are not generalizable past the local context (which most good randomistas already know), limiting their ability to help us transform how we do development.  In a world of global environmental change, our current approaches to development just replicate our existing challenges: they don’t really tell us if what we are doing will be of any lasting benefit, or even teach us general lessons about how to deliver short-term benefits in a rigorous manner.

Why should the aid/relief/development community care about global environmental change (Pt. 2)?

Yesterday, I took the relief community to task for not spending more time seriously thinking about global environmental change.  To be clear, this is not because that community pays no attention, or is unaware of the trend toward increasing climate variability and extreme weather events in many parts of the world that seems to be driving ever-greater needs for intervention.  That part of the deal is pretty well covered by the humanitarian world, though some folks are a bit late to the party (and it would be good to see a bit more open, informal discussion of this – most of what I have seen is in very formal reports and presentations).  I am more concerned that the humanitarian community gives little or no thought to the environmental implications of its interventions – in the immediate rush to save lives, we are implementing projects and conducting activities that have a long-term impact on the environment at scales ranging from the community to the globe.  We are not, however, measuring these impacts in really meaningful ways, and therefore run the risk of creating future problems through our current interventions.  This is not a desirable outcome for anyone.
But what of the development community, those of us thinking not in terms of immediate, acute needs as much as we are concerned with durable transformations in quality of life that will only be achieved on a generational timescale?  You’d think that this community (of which I count myself a part) would be able to grasp the impact of climate change on people’s long-term well-being, as both global environmental changes (such as climate change and ecosystem collapse) and development gains unfold over multidecadal timescales.  Yet the integration of global environmental change into development programs and research remains preliminary and tentative – and there is great resistance to such integration from many people in this community.
Sometimes people genuinely don’t get it – they either don’t think that things like climate change are real problems, or fail to grasp how it impacts their programs.  These are the folks who would lose at the “six degrees of Kevin Bacon” game – I’ve said it before, and I will say it again: global environmental change is development’s Kevin Bacon: I can link environmental change to any development challenge in three steps or less.  Sometimes the impacts are really indirect, which can make this hard to see.  For example, take education: in some places, climate change will alter growing seasons such that farm productivity will be reduced, forcing families to use more labor to get adequate food and income, which might lead parents to pull their kids from school to get that labor.  Yep, at least some education programs are impacted by climate change, an aspect of global environmental change.
Other times, though, I think that the resistance comes from a very legitimate place: many working in this field are totally overtaxed as it is.  They know that various aspects of global environmental change are problems in the contexts in which they work, but lack the human and financial resources to accomplish most of their existing tasks. Suddenly they hear that they will have to take something like climate change into account as they do their work, which means new responsibilities that will entail new training, but often come without new personnel or money.  It is therefore understandable when these folks, faced with these circumstances, greet the demand for the integration of global environmental change considerations into their programs with massive resistance.
I think the first problem contributes to the second – it is difficult to prioritize people and funding for a challenge that is poorly understood in the development community, and whose impacts on the project or initiative at hand might be difficult to see.  But we must do this – various forms of global environmental change are altering the future world at which we are aiming with our development programs and projects.  While an intervention appropriate to a community’s current needs may result in improvements to human well-being in the short term, the changes brought on by that intervention may be maladaptive in ten or twenty years and end up costing the community much more than it gained initially.
Global environmental change requires us to think about development like a fade route in football (American), or the through ball in soccer (the other football).  In both cases, the key is to put the ball where the target (the receiver of the pass) is going to be, not where they are now.  Those who can do this have great success.  Those that cannot have short careers.  Development needs to start working on its timing routes, and thinking about where our target communities are going to be ten and twenty years from now as we design our programs and projects.
So, how do we start putting our projects through on goal?  One place to start would be by addressing two big barriers: the persistence of treating global environmental change as a development sector like any other, and the failure of economics to properly cost the impacts of these changes.
First, global environmental change is not a sector.  It is not something you can cover in a section of your project plan or report, as it impacts virtually all development sectors.  Climate change alters the range and number of vectors for diseases like malaria.  Overfishing to meet the demands of consumers in the Global North can crush the food security of poor coastal populations in the Global South.  Deforestation can intensify climate change, lead to soil degradation that compromises food security, and even distort economic policy (you can log tropical hardwoods really quickly and temporarily boost GNP in a sort of “timber bubble”, but eventually you run out of trees and those 200-500 year regrowth times means that the bubble will pop and a GNP downturn is the inevitable outcome of such a policy).  If global environmental change is development’s Kevin Bacon, it is pretty much omnipresent in our programs and projects – we need to be accounting for it now.  That, in turn, requires us to start thinking much longer term – we cannot design projects with three to five year horizons – that is really the relief-to-recovery horizon (see part 1 for my discussion of global environmental change in that context).  Global environmental change means thinking about our goals on a much longer timescale, and at a much more general (and perhaps ambitious) scale.  The uncertainty bars on the outcomes of our work get really, really huge on these timescales . . . which to me is another argument for treating development as a catalyst aimed at triggering changes in society by facilitating the efforts of those with innovative, locally-appropriate ideas, as opposed to imposing and managing change in an effort to achieve a narrow set of measurable goals at all costs.  My book lays out the institutional challenges to such a transformation, such as rethinking participation in development, which we will have to address if this is ever to work.
Second, development economics needs to catch up to everyone else on the environment.  There are environmental economists, but not that many – and there are virtually no development economists that are trained in environmental economics.  As a result, most economic efforts to address environmental change in the context of development are based on very limited understandings of the environmental issues at hand – and this, in turn, creates a situation where much work in development economics either ignores or, in its problematic framings of the issue, misrepresents the importance of this challenge to the development project writ large. Until development economists are rewarded for really working on the environment, in all its messiness and uncertainty (and that may be a long way off, given how marginal environmental economists are to the discipline), I seriously doubt we are going to see enough good economic work linking development and the environment to serve as a foundation for a new kind of thinking about development that results in durable, meaningful outcomes for the global poor.  In the meantime, it seems to me that there is a huge space for geographers, anthropologists, sociologists, political scientists, new cultural historians, and others to step up and engage this issue in rich, meaningful ways that both drive how we do work now and slowly force new conversations on both economics and the practice of development.
I do admit, though, that my expanding circle of economics colleagues (many of which I connected to via this blog and twitter) have given me entrée into a community of talented people that give me hope – they are interested and remarkably capable, and I hope they continue to engage me and my projects as they go forward . . . I think there is a mutual benefit there.
Let me be clear: the continuing disconnect between development studies and environmental studies is closing, and there are many, many opportunities to continue building connections between these worlds.  This blog is but one tiny effort in a sea of efforts, which gives me hope – with lots of people at work on this issue, someone is bound to succeed.
In part three, I will take up why global environmental change means that we have to rethink the RCT4D work currently undertaken in development – specifically, why we need much, much better efforts at explanation if this body of work is to give us meaningful, long-term results.

Why should the aid/relief/development community care about global environmental change (Pt. 1)?

I’ve been at this blogging thing for a little over 13 months, and on twitter for maybe nine months.  I’ve found both venues tremendously productive – I feel like I have a whole new community to which I belong that has helped to expand my horizons and change some of my perspectives on development and aid.  Nearly every day I learn something from the folks I am connected to via these social media – and that is the highest praise I can offer anyone or anything.  I get bored easily, and when I am bored I get cranky.  My wife thanks you for keeping me interested and amused.
So, after 13 months I think I have a sense of the landscape around these here development/aid parts . . . and I am stunned to realize there is something missing.  How is this blog the only one I know of that engages both development and global environmental change at roughly equal depths?  Well, this one and Global Dashboard, sort of . . . I do like Global Dashboard, though.
Now, I can see why the aid/relief (as opposed to aid/development focused – see my parsing below) blogs really don’t spend a ton of time on climate change – mostly, they are coming from the front lines of work, the sharp end of the implementation spear, as it were.  Folks are caught in the immediacy of response to disaster, or buried in the myriad small tasks that can completely overwhelm staff at the implementation end of a recovery project.  There is an existential quality to these blogs, because there is an existential quality to that existence.  I can understand this.
Then there are the aid/development blogs – those that are focused on thinking about the long-term transition from poverty to something better for the global poor.  Yes, aid is part of how we address this challenge, but really development is about long-term social, economic and political transformation.  It does not unfold in rapid manner, and therefore lends itself to more protracted musings.  Further, because aid/relief is focused on an acute situation, there is a short time horizon for planning and thinking – ideally with some sort of handover to long-term development programs, though we all know this does not happen as often or as smoothly as anyone would like.  Aid/development, on the other hand, has a much longer time horizon – the intervention, ideally, should be producing results on a generational timescale (project reporting requirements aside, of course).  Yet even on these blogs, I see very little attention being paid to climate change or environmental change – though these are processes that are likely transforming the very future worlds we are planning toward with our development projects and policies.
Here’s the thing: both the relief and development communities need to be thinking about global environmental change. Period.
Today, my thoughts for the aid/relief blogs and thinkers – and I offer this with genuine sympathy for their situations as acute responders who are overburdened by various administrative requirements: climate/environmental change is not somebody else’s problem.  Nobody wants to hear this when they are on the front lines, as it were, but how we do relief and recovery has tremendous implications for global environmental change . . . and of course these changes will shape a lot of relief and recovery going forward.  I know that most relief agencies start from the mandate of saving lives – everything else is secondary to that.  I respect this . . . but it does not exclude the idea of thinking about and addressing environmental issues in their work.  If we are serious about saving lives, lots of lives, we’d better get ahead of the curve in thinking about future response needs – what is going to happen, and where.  For example, we expect to see ever-greater climate variability over the next several decades, which means that we are going to see less predictable weather, and perhaps more extreme weather events, in many places.  While there is a great deal of uncertainty surrounding the timing of these events and the ranges of variability we might see, we are already coming to understand where some of the most acute changes are taking place (a lot of them in Africa, sadly) – and we can plan our resources for those areas.  At the same time, we see fisheries collapsing around the world, with huge impacts on the diets and well-being of onshore communities – we know exactly where these events are happening, and we know exactly why, so we certainly can plan for this slow onset emergency.
As we think about recovery programs, we will have to do more than put it back as it was (the common mandate) . . . we will have to help build something that has the flexibility and resilience to adapt to a changing future.  Neither of these efforts requires a fundamental rethinking of relief and recovery work, just some will to spend a few minutes BEFORE a disaster happens to think through how to address these challenges.
More difficult is thinking through the impact of our relief and recovery efforts on the global environment.  What we use for temporary shelters, how we move and dispose of rubble, where we procure food aid, all of these things and much more result in varying levels and types of environmental impact.  When we are busy saving lives in the here and now, I understand it can be hard to think about these issues – but many times we botch this part of the relief work, creating long-term environment and health issues that end up costing lives.  Our recovery work often recommends new land uses and agricultural strategies, which have ecological and greenhouse emissions ramifications.  We often suggest new livelihoods practices, which involve the use of new natural resources, and therefore introduce new environmental impacts with uncertain long-term ramifications. Someone needs to do an accounting of how many lives are saved in the immediate post-disaster setting by ignoring these issues, and how many are lost over the longer term by the impacts of ignoring these issues.  I am willing to wager that there are many cases were the long-term losses exceed the short-term saved . . . mostly because I am not all that convinced that considering such issues will really slow things down that much if we have decent forward planning.  This holds true even for the greenhouse emissions – I wonder how many extra tons of carbon we put out unnecessarily each year because we don’t consider the greenhouse implications of our relief/recovery work?  Further, I wonder if those emissions are contributing in a meaningful way to the climate change trends that we see globally, or if they are just tiny noise in a giant ocean of emissions.  If these emissions are the latter, then I think we are free to ignore them . . . but I don’t see anyone presenting that data.
So, to summarize for my aid/relief colleagues, despite your completely overtaxed, over-mandated and over-paperworked lives, you need to be reading blogs like Global Dashboard, Climate Science Watch, and RealClimate (OK, RealClimate is probably too technical).  You need to become aware of the Intergovernmental Panel on Climate Change, and familiarize yourself with the Working Group 2 report (human impacts) – it gives you the scientific community’s best assessment of what the coming challenges are, and where they will occur.  When the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation goes public, that will be a crucial tool.  All the IPCC stuff is free for download, and written in relatively clear language (well, clear compared to the journals).  The Millennium Ecosystem Assessment might be useful, too – check the Current States and Trends report.  And, failing that, keep reading this blog – even the posts on climate change.  You’ll find them useful, I swear.
Next up:  the aid/development argument: seriously, I need to go over this? Fine, fine . . .

Much of the scientific case for climate change, in a single graphic

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 . . .

Early warning for climate tipping points

One of the things I am (not so) fond of saying is that when it comes to climate, I am not really worried about what I do know – it’s the things that I don’t know, and cannot predict, that worry me the most. The climate displays many characteristics of a nonlinear complex system, which means that we cannot assume that any changes in this system will come in a steady manner – even a fast but steady manner. Instead, the geologic record suggests that this system changes in a linear manner (i.e. slowly warms up, with related shifts in sea level, precipitation, wind patterns and ocean circulation) up to a certain point before changing state – that is, shifting all of these patterns rather dramatically into a new state that conveys the extra energy in the atmosphere through the Earth system in a different manner. These state changes are frightening to me because they are highly unpredictable (we are not sure where the thresholds for these changes are) and, at their worst, they could introduce biophysical changes like increased temperature and rates of evaporation and decreased rainfall with such speed (i.e. in a decade or two, as opposed to over centuries) that the rate of change outpaces the capacity of biomes to adapt, and the constituent species in those biomes to evolve. This is not some random concern about biodiversity – people seem to forget that agricultural systems are ecosystems; radically simplified ecosystems, to be sure, but still ecosystems. They are actually terribly unstable ecosystems because they are so simple (they have little resilience to change, as there are so few components that shifting any one of them can introduce huge changes to the whole system), and so the sort of nonlinear changes I am describing have particular salience for our food supply. I am not a doomsday scenario kind of guy – I like to think of myself as a hopelessly realistic optimist – but I admit that this sort of thing worries me a lot.
So, to put this another way: we are running like hell down a long hallway toward an open door into a darkened room. We can’t see what’s in the room, and it is coming up fast. Most normal people would probably slow down and enter the room cautiously so as to avoid a nasty collision with something in the dark. When it comes to climate change, though, our current behavior is akin to running right into that room at full speed and hoping with all our might that there is nothing in the way.
This is a really, really stupid way of addressing the challenge of climate change.
The good news on this front is that we are starting to see the emergence of a literature on the early warning for these tipping points. I had a post on this recently, and now the July issue of Nature Climate Change has a review article by Timothy Lenton on early warning of tipping points. It is a really excellent piece – it lays out what we are currently doing, shows the limitations of what we can do, points to significant challenges both in the science and in the policy realm, and tries to chart a path forward. I think Lenton comes in a bit science-heavy in this piece, though. While he raises the issues of false alarms and missed alarms, he spends nearly all his time looking at methods for reducing the occurrence of these events. This is all well and good, but false and missed alarms are inevitable when trying to predict the behavior of complex systems. Yes, we need more and better science, but we also need to be thinking about how we address the loss of policymaker confidence in the wake of false alarms or missed alarms.
To get to this point, I think we need to be looking to arenas where people have a lot of experience communicating levels of risk and the importance of addressing that risk – the insurance industry. Most readers of this blog will have some form of insurance – be it health insurance, life insurance, car insurance, etc. I have all three. Every month, I pay a premium for a product I sincerely hope I never have to use. I’d rather hang on to that money (with a family the size of mine, it gets steep), but the cost of a catastrophic event in any of these areas would be so high that I gladly continue to pay. We need to encourage the insurance industry (they are already working on this issue, as they stand to lose a hell of a lot of money unless they can get their actuarial tables adjusted) to start communicating their sense of the likely future costs of climate change, and the costs associated with potential state changes – and do so in the same way that they sell us insurance policies. Why do we have scientists working on the marketing of our ideas? We are not trained for this, and most of my colleagues lack the salesman’s charisma that the climate change issue so desperately needs.
It’s time for a serious conversation about how science and the for-profit risk management world can start working together to better translate likely future climate impacts into likely future costs that everyone can understand. Science simply does not carry the weight we need in policy circles – the good data and rigorous analysis that are central to scientific legitimacy are, in the policy realm, simply seen as means to achieving a particular viewpoint, not an ever-improving approximation of how the world works. Until the climate science (and social science) community grasps this, I fear we will continue to talk past far too many people – and if we allow this to happen, we become part of the problem.

Stories, development and adaptation

Mike Hulme has an article in the July issue of Nature Climate Change titled “Meet the humanities,”[paywalled] in which he argues that “An introduction needs to be made between the rich cultural knowledge of social studies and the natural sciences.”  Overall, I like this article – Hulme understands the social science side of things, not least through his own research and his work as editor of Global Environmental Change, one of the most influential journals on the human dimensions of global change*.  Critically, he lays out how, even under current efforts to include a wider range of disciplines in major climate assessments, the conversation has been dominated for so long by the biophysical sciences and economics that it is difficult for other voices to break in:

policy discussions have become “improving climate predictions” and “creating new economic policy instruments”; not “learning from the myths of indigenous cultures” or “re-thinking the value of consumption.”

Hulme is not arguing that we are wrong to be trying to improve climate predictions or develop new economic policy instruments – instead, he is subtly asking if these are the right tools for the job of addressing climate change and its impacts.  My entire research agenda is one of unearthing a greater understanding of why people do what they do to make a living, how they decide what to do when their circumstances change, and what the outcomes of those decisions are for their long-term well being.  Like Hulme, I am persistently surprised at the relative dearth of work on this subject – especially because the longer I work on issues of adaptation and livelihoods, the more impressed I am with the capacity of communities to adjust to new circumstances, and the less impressed I am with anyone’s ability to predictably (and productively) intervene in these adjustments.
This point gets me to my motivation for this post.  Hulme could not cover everything in his short commentary, but I felt it important to identify where a qualitative social science perspective can make an immediate impact on how we think about adaptation (which really is about how we think about development, I think).   I remain amazed that so many working in development fail to grasp that there is no such things as a completely apolitical, purely technical intervention. For example, in development we all too often assume that a well is just a well – that it is a technical intervention that delivers water to people.  However, a well is highly political – it reshapes some people’s lives, alters labor regimes, could empower women (or be used as an excuse to extract more of their labor on farms, etc.) – all of this is contextual, and has everything to do with social relations and social power.  So, we can introduce the technology of a well . . . but the idea and meaning of a well cannot be introduced in the same manner – these are produced locally, through local lenses. It is this basic failure of understanding that lies at the heart of so many failed development projects that passed technical review and various compliance reviews: they were envisioned as neutral and technical, and were probably very well designed in those arenas.  However, these project designers gave little concern to the contextual, local social processes that would shape the use and outcomes of the intervention, and the result was lots of “surprise” outcomes.
When we start to approach these issues from a qualitative social scientific standpoint, or even a humanities standpoint (Hulme conflates these in his piece, I have no idea why.  They are not the same), the inherent politics of development become inescapable.  This was the point behind my article “The place of stories in development: creating spaces for participation through narrative analysis.”  In that article, I introduce the story I used to open Delivering Development to illustrate how our lived experience of development often plays out in ways best understood as narratives, “efforts to present information as a sequence of connected events with some sort of structural coherence, transforming ‘the real into an object of desire through a formal coherence and a moral order that the real.”  These narratives emerge in the stories we are told and that we overhear in the course of our fieldwork, but rarely make it into our articles or reports (though they do show up on a few fantastic aid blogs, like Shotgun Shack and Tales from the Hood).  They become local color to personal stories, not sources of information that reveal the politics of our development efforts (though read the two aforementioned blogs for serious counterpoints).
In my article, I demonstrated how using the concept of narrative, drawn from the humanities, has allowed me to identify moments in which I am placed into a plot, a story of development and experience not of my making:

In this narrative [“the white man is so clever,” a phrase I heard a lot during fieldwork], I was cast as the expert, one who had knowledge and resources that could improve their lives if only I would share it with them. [The community] cast themselves in the role of recipients of this knowledge, but not participants in its formation.  This narrative has been noted time and again in development studies (and post-colonial studies), and in the era of participation we are all trained to subvert it when we see it emerge in the work of development agencies, governments, and NGOs. However, we are less trained to look for its construction by those living in the Global South. In short, we are not trained to look for the ways in which others emplot us.

The idea of narrative is useful not only for identifying when weird neocolonial moments crop up, but also for destabilizing those narratives – what I call co-authoring.  For example, when I returned to the site of my dissertation fieldwork a few years later, I found that my new position as a (very junior) professor created a new set of problems:

This new identity greatly hindered my first efforts at fieldwork after taking this job, as several farmers openly expected me to tell them what to plant and how to plant it. I was able to decentre this narrative when, after one farmer suggested that I should be telling him what to plant instead of asking him about his practices, I asked him ‘Do I look like a farmer?’ He paused, admitted that I did not, and then started laughing. This intervention did not completely deconstruct his narrative of white/developed and black/developing, or my emplotment in that narrative. I was still an expert, just not about farming. This created a space for him to speak freely to me about agriculture in the community, while still maintaining a belief in me as the expert.

Certainly, this is not a perfect outcome.  But this is a lot better than the relationship that would have developed without an awareness of this emerging narrative, and my efforts to co-author that narrative.  Long and short, the humanities have a lot to offer both studies of climate change impacts and development – if we can bring ourselves to start taking things like stories seriously as sources of data.  As Hulme notes, this is not going to be an easy thing to do – there is a lot of inertia in both development and climate change studies.  But changes are coming, and I for one plan to leverage them to improve our understandings of what is happening in the world as a result of our development efforts, climate change, global markets, and any number of other factors that impact life along globalization’s shoreline – and to help co-author different, and hopefully better, outcomes than what has come before.

A guide to critically reading sources of climate misinformation (or, as I call it, mendacious crap)

. . . ladies and gentlemen, I give you Pat Michaels’ absurd Climate of Fear blog!  I’ve already posted on what I thought was a remarkably problematic post from this blog, and I am coming to realize that addressing the mountain of garbage that emerges from this source could become a semi-full time job, and I just don’t have that kind of time.  So, rather than work through each post (and they all need attention, as they are all rife with misdirection, internal contradictions, factual inaccuracies, and what I can only call staggering ethical lapses), I’d like to lay out a loose framework for critically reading Michaels’ entries that anyone can use.
First, look for internal contradictions: In his post “Big Science, Big Government,” Michaels subtly identifies himself as a scientist (he obviously feels the need for that legitimacy)  by saying “My lobby, the American Association for the Advancement of Science (AAAS) isn’t located in Washington, D.C., because its employees are fond of the city’s heat and humidity in the summer.” (Full disclosure – I am currently on an AAAS Science and Technology Policy Fellowship).  Obviously, he feels fine about advocacy from his position as a scientist, as he is writing opinion pieces for Forbes.com and now works for the Cato Institute.  Despite this, he sees no irony at all in arguing, in the context of a huge banner supporting AAAS advocacy for biofuels (which I have long disagreed with, incidentally), that  “The image [on the banner] was hardly neutral.  Backgrounding the corncob/gasoline pump is an image of a wild blue (i.e. pollution-free) ocean.  This was propaganda and public relations, not science.”
Well, technically he is correct – this was advocacy, no doubt.  But Pat, your blog is propaganda and PR, not science.  So why is this a problem for AAAS, but fine for you?  Either we are looking at a serious internal contradiction, or an ethical lapse around the failure to disclose his own advocacy.
Oh, and Pat, UVa is one of the “Public Ivies,” not one of the “Public Ivy’s.”
Second, look for misdirection: In “Voodoo Economics? How About Voodoo Climate Science,” Michaels actually rightly points out a number of problems with the last IPCC report (again, full disclosure – I am a review editor for the upcoming 5th Assessment Report of the IPCC).  Well, he throws a spurious temperature claim in there, but then this is par for the course on his blog.  He then constructs a stunning argumentative fallacy – he finds six errors in a report that runs several thousand pages in its entirety, argues they are all biased in the same direction, and then makes the argument that the odds of six errors in a report of this size aligning in the same direction rises to the .02 level of significance (to break out the stats).
Now, some of the errors to which he points require attention – for example, climatologists I know who focus on hurricanes and cyclones have long said that climate change would have an uncertain impact on these storms because their formation is very complex, and a lot of different factors that contribute to their formation were being altered by climate change – in other words, the uncertainty to which Michaels (rightly) points is the product of climate change.  Oopsie.  This is what we call misdirection . . .
Third, look for spurious arguments (and structures of argument): Aside from tiny internal fallacies such as I just described in the “Voodoo” post described above, the entire structure of Michaels’ argument in this post is crap.  Michaels does not address errors of understatement in the report – which, by his standards, are examples of bias in favor of his position.  For example, the Arctic Sea Ice is disappearing much faster than projected in the last report – so does this mean that the authors of that chapter are in bed with Pat Michaels and the rest of the climate denial crowd?  Er, no.  It means that this chapter was written with the best evidence at the time, and now we have better evidence.  When we start looking for errors of understatement, we find that this report was often far too conservative – and the number of cases where the estimates or interpretations were too conservative (i.e. arctic sea ice) outweigh Michaels’ pathetic six cases.  Michaels is cherrypicking the data (in this case, the data are the examples of errors in the report) to get the result he wants . . . which would get him slapped down in any scientific outlet.
Finally, look for evidence for Michaels’ real fear – that markets might not work perfectly, and that government regulation of activities that affect the environment might actually be needed to correct for the obvious market failures that are occurring around greenhouse gas emissions:  For example, look at the title of the post “Voodoo Economics? How About Voodoo Climate Science”, Michaels never actually makes reference to George H. W. Bush’s critique of Reagan’s supply-side economics – yet somehow it is in this post.  Perhaps because Michaels is defending that supply-side position against the threat of regulation and taxation?  This blog is a frequently updated proof that Oreskes and Conway were really on to something in their exploration of the anti-science movement Merchants of Doubt.  In a nutshell, they argue that people like Michaels are not motivated by real curiosity, empirical data, or scientific consensus – they are driven by a broadly neoliberal agenda that emerged in the Cold War and still sees itself as the protector of the American Way from the path of regulation and taxation that leads to Communism and other forms of totalitarianism.  Except, of course, that this is more than an argument about politics and economics – this is an argument about what to do in a changing world . . . where one group participating in the argument has its fingers in its ears and is shouting “lalalalala” as loud as it can whenever actual data appears.
So, read away – you can make a game out of identifying the misdirections, misrepresentations, internal contradictions, barely concealed neoliberal freakouts, and much more rare overt neoliberal freakouts as you go.  But look for all of these, and understand that Climate of Fear is not a source of information, it is an effort to obscure the problem in the name of a long-discredited political-economic agenda . . .

A development economics of finitude?

Just a very quick thought today.  After reading Charles Kenny’s Getting Better and skimming Owen Barder’s “Can Aid Work?“, I’m wondering if anyone else can hear the faint rumblings of something very important – here we have two people, hardly from the fringes of development thought, noting variously that 1) aid does not seem well-correlated with economic growth, and therefore a clear causal relationship is pretty hard to determine and 2) despite this, and in several cases in the absence of major economic growth, things seem to be getting better in a number of places (this second point is mostly Charles).  In other words, are we seeing arguments against a focus on economic growth in development shift from the margins to the center of development thinking?
Those of us more on the qualitative social theory fringes of the field have long been arguing that the worship of growth did not make much sense, given what we were seeing on the ground.  Further, the emergence of the anthropocene (the recent era of human dominated environmental events) as a direct outcome of more than a century of concerted efforts to spur ever-faster economic growth, calls into question the wisdom of a continued myopic focus on growth without a serious consideration of its costs and potential material limits.  So if indeed we are seeing the beginnings of a shift in policy circles,  I am thrilled.  Nothing will change tomorrow, but I think these interventions might be important touchstones for future efforts to create some sort of development economics of finitude . . .
