Life on Concrete

A few weeks ago there was a mouse in the street. Upon a closer look, it seemed like it was confused or injured, running in circles. The road was busy with cars and I almost jumped out into traffic to try to usher the mouse to the sidewalk, but was prevented from doing so (maybe for the best, I don’t know). In any case, some time later when we came back, it was clear the mouse had been killed by a car.

In the last year or two I’ve taken on a behavior that baffles me at the moment I’m acting it out. I find myself along some piece of concrete in the city — a sidewalk, a curb, a street — and I see some other fellow inhabitant of the Earth there, and I want to ensure that they can continue to live as I do, free from harm.

After a heavy rain, the sidewalks everywhere are writhing with earthworms, trying to get out of the water-logged heavy clay soils and into someplace more habitable. Unfortunately, that’s not the sidewalk. Here too I’ve found myself, even when with others, almost automatically finding a leaf or a stick to scoop up the worms and return them to a patch of soil that’s safer.

It’s not just a mouse or earthworms — I’ve found myself doing this for squirrels, birds, ladybugs, and others. One of the more traumatic was the case of a bird that flew into our apartment window a couple of years ago — I heard a noise and saw a small bird (a sparrow, maybe) on the ground next to the window. I gently picked the bird up and could see the bird struggling to breathe, making what looked like gasping motions. The bird’s feathers were soft and body slight. I wanted to let the bird have a chance of recovery if that were even possible, and found a secluded spot under the deck for the bird to rest. Unfortunately, when I returned a few hours later, the bird had perished, and I found a good final resting place in a snow bank.

I know I’m inconsistent about it, in that a readily pick off caterpillars from plants I’m growing and leave them for birds to catch, and I’m not sure if that’s any different from letting some other being die on the pavement — I’m sure there are ethicists who have thought about this question far more deeply than I have. And this inconsistency is probably nothing new to those who live on farms.

But when I see plants scratching out an existence in the cracks of some forgotten piece of sidewalk or an abandoned lot, it gives me an odd sense of happiness — life finding a way despite our best efforts. Same goes for crows that manage to find something to eat in industrial office parks. Maybe what’s driving my impulse is something like the inverse of the phenomenon I mentioned in a previous post where techno-fix solutions are seemingly judged by the immensity of their struggle against nature. I suppose I see helping those other animals around us, in the decidedly human environment of city concrete, as honoring their role in the world around us.

Economy << Ecosystem

Today it hit me that the model of the economy and the ecosystem in ecological economics is more right than I had previously understood. The work of Herman Daly and others made sense before today, with its key premise that the human economy is a subset of the ecosystem. This is something neoclassical economists, not to mention environmental economists, tend to ignore or deny.

What I didn’t realize before, though, is this: not only is the global economic system a subset of the global ecosystem, but it is an ecosystem even though we don’t think of it that way. An ecosystem roughly speaking involves energy flows between biological, geological, and chemical entities and processes. That’s what an economy consists of as well — flows of energy, food, minerals, water, and then derived goods that are built upon those foundations. A bird gathering twigs that were produced by a tree to build a house is no different than a human gathering lumber from the hardware store that was produced by a tree to build a house. The term economy could apply in both contexts, and so the distinction between the two is a false one. While non-humans, to our knowledge, don’t use currencies to mediate their exchanges, they use a vast array of mechanisms to interact and exchange energy and resources with each other; consider the symbiosis that takes place among coral or in any mycorrhizal association, to pick two among millions of examples.

Once this linguistic substitution is made, the false premises of conventional economics are more apparent. For example, imagine reading a recent news headline while applying this substitution:

China’s ecosystem growth slows to 7.7%

The absurdity of it is immediately apparent when framed that way: the only way for China’s economic ecosystem (or any type of ecosystem for that matter) to grow is to expand its boundaries — that is, to appropriate flows from outside its current boundaries. Thus we can return to Daly’s dictum with confidence:

[T]he economy is an open subsystem of a finite and nongrowing ecosystem (the environment). The economy lives by importing low-entropy matter-energy (raw materials) and exporting high-entropy matter-energy (waste). Any subsystem of a finite nongrowing system must itself at some point also become nongrowing.

Networking for Undeveloping Regions

I wrote the short position paper below, with a bit of help from a colleague, for an academic audience, but never published it. Today I was thinking about it and realized that it synthesizes some of my thinking on computing and economic trends. For the last decade there has been an active area of computing research sometimes called ICTD (Information and Communication Technologies for Development) or Developing Regions computing research, largely focused on bringing to bear computing to solve the problems of industrializing nations. For the moment I’d like to set aside both the problems with the term “development” and the fact that much of such work is unlikely to succeed in the ways its proponents think it will (Toyama’s take on this is well worth reading, and is a good counterpoint to the much more mainstream ideas of the One Laptop Per Child project, among others). Nevertheless, some of the research that’s been done has been worthwhile in that it’s been forced to work within limits, both energy and financial, but many in this field aren’t that familiar with the broader issues of Limits to Growth. That’s where this paper begins.


1. Introduction

A simple view of the world’s nations yields a comforting binary: developed nations, those that have industrialized, and developing nations, those aspiring to their example. It is in this context, for the most part, that work on development in general and ICTD in particular has operated, and by and large this has been a success and a boon to those in developing nations. In this paper, we complicate this view by adding a third, heretofore unexamined category—undeveloping regions—and discuss both the need to consider ICT broadly and networking in particular in this new context.

Recent studies indicate that energy costs will rise substantially in the coming years, due primarily to the increasing difficulty of locating and extracting fossil fuels [10, 17]. Rising energy costs, increasing demands [3], ecological limits [13], and economic consequences [7] will force a fundamental change in the world’s economies, and yet due to the scale of the challenge and the lack of preparation for a transition, the effects are expected to be significant; a 2005 study commissioned by the U.S. Department of Energy concluded [10]:

“Virtually certain are increases in inflation and unemployment, declines in the output of goods and services, and a degradation of living standards. Without timely mitigation, the long-run impact on the developed economies will almost certainly be extremely damaging, while many developing nations will likely be even worse off.”

Thus the world is on a collision course: already-high resource consumption/environmental impacts in developed nations and increasing in developing ones collide with resource limits and broader ecological overshoot. We can loosely define undeveloping regions as largely today’s high socioeconomic regions that as a result of these challenges are likely, in some form or another, to face degradation of their social and economic systems. In this we also include a second somewhat distinct category: currently developing regions whose industrialization is likely to slow, stall, or reverse. In Section 2 we attempt to identify the contours of such regions in order to inform research directions.

Given these challenges, how might ICTD researchers respond? We are outsiders to the ICTD community, and as such this paper is both a challenge and a plea to the community: a challenge to consider how these new global challenges will affect the context in which ICTD work is done and a request for help from the ICTD community to apply the hard-won knowledge of today’s ICTD to these soon-to-be undeveloping regions that comprise both today’s developed world and the developing world. In these new environments, both the target objectives and the constraints are likely to be different from the environments seen today. For example, research objectives in undeveloping regions are likely to focus lower on Maslow’s hierarchy, on more prosaic but more fundamental human needs, just as ICTD work has done in developing regions, than does today’s developed-world networking research. Similarly, the environments of undeveloping regions are likely to have different infrastructure availability and financial constraints, finance and culture, than seen anywhere today. In particular, today’s developed nations often lack indigenous cultures of self-sufficiency (in large part because they were supplanted long ago) and as a result are likely to prove to be as challenge rich environments as ICTD is today.

Thus we are both proposing a new direction for research in both the ICTD community and the broader networking community, and hoping to outline the circumstances and challenges that will help inform future designs in this space; we discuss these in detail in Section 3. In particular, we contend that the goals of Appropriate Technology are ones aligned with the needs of undeveloping regions, and that using networked systems to help decrease complexity and increase transparency of socioeconomic systems will be of particular value.

Finally, there remains a sensitive topic to discuss: why those in the ICTD community should be interested in the challenges to be faced by currently-developed regions; after all, the latter have significant resources to address their own problems. A natural response would be to ignore these challenges, expecting the fates of undeveloping regions to be separate from today’s developing regions. On the contrary, however, as these challenges progress, it is likely that the circumstances and fates of those in currently-developed and currently-developing regions will increasingly be shared, as suggested by a number of analyses [10, 13, 9, 14]. It is for this reason that we do not attempt to artificially separate the two, and consider both categories within the moniker “undeveloping regions.” Beyond this matter of shared fate, we also believe that the community has significant knowledge to contribute to a shared vision of what networking and ICT can look like in this common future.

2. Case Studies

Before we attempt to define undeveloping regions, we first look at two related questions: what is the nature of near-term global challenges, and how might those challenges manifest in terms that help us identify appropriate ICTD-like responses?

For the first, we briefly summarize previous work on the subject detailing the contours of the challenges ahead. For the second, in the absence of true ethnography detailing life in undeveloping regions (since we are, after all, discussing future circumstances whose specifics are unknowable today), we must consider a substitute. As such, we examine four recent historical instances in which crises befell nations. We do this in an attempt to glean common characteristics that might inform the challenges that lay ahead, not to predict any specific crisis or circumstance. Our examples lay somewhat along a spectrum from isolated and monolithic problems to pervasive and broad-based problems: Argentina experienced a financial crisis, Greece a financial crisis along with endemic economic problems, the United States two temporary oil crises, and the Soviet Union systemic collapse.

2.1. Background In a recent paper, we described the challenges that networking will broadly face as energy and ecological limits are reached, most likely some time this decade. Specifically, we discuss energy limits—oil production in particular—why alternatives are unlikely to serve as adequate substitutes in the required timeframe, and the likely economic consequences. As a result, developed and developing nations alike are likely to face widespread economic and social challenges over at least the span of decades. We refer interested readers to a number of works on the broader topic [12, 13, 9, 14] for additional details.

In short, the impending challenges are not just due to the limits of oil production, but the panoply of issues faced by global society today. Among these are climate change [13], stagnant food production per capita, and broad ecological overshoot [20]. In addition, rapid development has put developed and developing nations on a collision course: if India and China were to maintain their current rate of growth for a little over a decade, together they would consume 100% of the crude oil available on the global market (i.e. of global net exports), even under the optimistic assumption of stable global oil production [3].

2.2. Argentina The case of Argentina, once seen as a development success story, is fraught with geopolitical intrigue but little actual complexity of cause or effect. Blustein provides a comprehensive analysis of the economic crises that befell Argentina, in part of its own doing, and in part due to actions by organizations such as the IMF [1]. While the cause of the challenges faced by Argentina largely differ from those described above, the societal issues faced may be instructive. Blustein describes how the impact of the financial crisis affected all social classes, the consumer economy, and the food system. Transportation systems, such as Argentina’s rail system, suffered. Despite this, perhaps due to the relatively short duration of the worst of the crisis, public health may have remained largely unaffected.

2.3. Greece The crisis currently unfolding in Greece today has similar roots as that of Argentina a decade earlier, though it bears greater similarity to the challenges we’re likely to face. As a recent report found [19]:

By many indicators, Greece is devolving into something unprecedented in modern Western experience. A quarter of all Greek companies have gone out of business since 2009, and half of all small businesses in the country say they are unable to meet payroll. The suicide rate increased by 40 percent in the first half of 2011. A barter economy has sprung up, as people try to work around a broken financial system.

At the same time, many Greeks are returning to agriculture, and the health system is struggling to meet even basic needs [5]. In some ways, the challenges Greece faces are harder to overcome than those of today’s developing nations, as few alternative systems—of food, finance, or health care—exist for the populace to fall back upon. While the financial origins of this crisis are well understood, there are compounding factors of energy-driven trade deficits, and the effect of high oil prices on tourism.

2.4. United States The oil crises experienced by the United States and other industrial nations during the 1970s resulted in sharp and deep recessions, and contributed to an extended period of economic uncertainty and stagnation. While the specific causes of the crises are superficially similar to the challenges we consider here, they differ in large part in that they were caused by geopolitical factors and thus were immediate but temporary whereas geological factors are likely to be gradual but fundamental. It is for this reason that Hirsch et al. note that “past ‘energy crisis’ experience will provide relatively little guidance” [10]. Nevertheless, they serve as an empirical reminder of the dependency of industrial economies upon energy in general and oil in particular.

2.5. Soviet Union While there are numerous historical examinations of the decline and fall of the Soviet Union, the work by Orlov on this subject is of particular note for its attempt to relate challenges the Soviet Union faced with that of impending challenges faced by today’s industrialized nations [15]. Orlov observes that many of the contributing factors and circumstances from the Soviet Union are present in the United States as well, and thus attempts to distill the ways in which the two differ as much as they share. In particular, he notes both face(d) declining oil production, unsustainable debt, unresponsive political and socioeconomic systems, and military conflict. In the post-collapse environment, he describes widespread social dislocation, shortages of basic commodities, foregone infrastructure maintenance, and the failure of new long term plans. Despite this, he notes that because the economic system was not market-based, a number of crucial sectors of society continued to function either as before or with bearable disruptions: housing, transportation, food production, medicine, education, and energy. In some of these, the Soviet systems were already somewhat dysfunctional but as a result individuals already had coping strategies (e.g. pervasive kitchen gardens); in others, the systems were government-run and thus collapse didn’t affect them (e.g. no foreclosures due to free housing; most transportation was public and supplied by domestic energy).

In contrast, the equivalent systems in free-market economies are both highly efficient but at the same time complex and interdependent; for example, one among many proximate causes of the 2008 economic crisis was the implosion of the housing bubble, which in part was caused by high energy prices which decreased demand for exurban sprawl, a cycle which fed on itself [9]. Thus there is some reason to believe, as Orlov contends, that many of the advantages of efficient free-market economies in times of growth can become disadvantages in times of hardship.

2.6. Undeveloping Regions One remarkable characteristic is that despite the fact that these crises had different origins, took place within different cultures and socioeconomic systems, and with different historical contexts, the effects on their populations were somewhat similar (though by no means the same). Though forecasts are sure to be wrong in their specifics (though perhaps not in their broad contours) the challenges we face are likely not only to be pervasive within nations and long-lasting, but also are likely to affect nations around the world. Thus the crises themselves are likely to interfere with efforts to mitigate them if the planning is postponed. In addition, it is our hope that in anticipating these challenges we both help mitigate them and also inform the design of better systems for not only undeveloping regions, but developing and developed regions as well.

We are not expecting a specific sharp inflection point at which a nation is no longer “developed”, nor are we expecting such a process to occur quickly. Instead, we expect a slow, grinding, and mostly transparent process of undevelopment that, while we expect it to begin this decade, will not fully play out for a few decades to come. Within this context, we also expect natural societal adjustments to respond to these challenges, responses which in some cases might improve circumstances (e.g. energy efficiency programs, relocalized health, education, and food production, etc.) and in some cases might do the opposite (e.g. last ditch efforts to produce liquid fuels from coal, tar sands, etc.).

It is unclear how long lived these challenges will be—will they last on the order of a decade or two, as in these historical examples, or will they be more persistent? Some have argued that the latter is more likely because the limits faced today are fundamental and pervasive [13, 9, 14]. Nevertheless, our goal here isn’t to adjudicate the matter; a decade or two is long enough to warrant our attention. Thus we turn our attention to three categories commonly targeted by ICTD research within which we can categorize the effects of the above historical crises.

Economics. Economic challenges are the clearest common thread in these four examples. In each, financial systems struggled as liquidity vanished and the grip of inflation took hold. As a result, consumer spending plummeted (in free-market economies) and thus both the industrial and service sectors were affected. In many ways, the economic effects appeared to be like a particularly severe recession, but with significantly longer duration.
Health. A prominent concern of the ICTD community has been public health. Peak oil, limits to growth, and climate change together are likely to present perhaps the biggest set of challenges to public health that have ever been faced in modern times [13], so facing these issues head on is a matter of public health in developing and undeveloping regions alike. A likely cause of problems will be the mismatch between today’s expensive and complex industrial medicine and the basic needs and financial means of the populace. A recent issue of the American Journal of Public Health featured eight papers on the special topic of Peak Petroleum and Public Health with a wide array of dire findings and possible mitigation approaches.
Transportation. As we face issues with the cost and availability of oil, and thus of transportation fuels, nations with oil-dependent transportation systems will find themselves hugely vulnerable. In addition, the expense and time commitment to build alternative systems, such as an extensive rail network, are prohibitive during times of crisis, as indicated by Argentina’s experience.

3. Challenges and Responses

Networked systems design, and systems design more broadly, is always about context: about building a system that optimizes some metrics within some design constraints. Thus far we have tried to outline the issues likely to be faced by those in undeveloping regions. Here we attempt to translate such issues into concrete research challenges—constraints within which the community will need to design within and possible responses. The constraints we identify often differ not only from today’s developed regions but from developing ones as well, though the similarities are as interesting as the differences.

Before we begin, we briefly make two disclaimers. First, it is very difficult to know that the constraints we identify are the right ones; only time will tell. We have tried our best to let the case studies and other background material inform them. Second, we are aware of the issue of generalizability—that while it is of value to deliver generalizable contributions in ICTD work, there is a danger of attempting to generalize from specific instances to circumstances that may in fact differ significantly [4].

3.1. A Comparison

Category Developed Regions Developing Regions Undeveloping Regions
Network Infrastructure Pervasive and advanced Spotty but advancing Varied and aging
Devices Contemporary Lagging but advancing Lagging and stagnant
Power Stable and ubiquitous Intermittent Intermittent but varied
Finance Stable and ubiquitous Stable but varied Unstable

A key difference in this challenge versus most ICTD work is that the design is in large part for the (potentially near) future, not today. In an attempt to capture the differences between the well-understood targets of developed and developing regions, and the undeveloping regions of the future, we summarize some qualities that may be pertinent to networked systems designers in the Table. In particular, we contend that undeveloping regions are likely to exhibit the unsurprising quality of slow or absent replacement of infrastructure and devices and general degradation of existing systems. The key difference between undeveloping regions and the developing regions of today is likely to be their starting point—many undeveloping regions may begin with a vast infrastructure and installed base which can serve as a buffer for some time. At the same time, they will be faced with a pervasive dependency on those systems for the functioning of interlinked social systems. Just as there are those in developing regions who are early adopters of ICT, whose combination of local knowledge and technical knowledge can prove important to the success of an ICTD project, there are some, though not many, autochthonous technology communities in developed countries [11], usually with an aim of independence (and sometimes sustainability).

It is just as worthwhile to examine what assumptions may no longer hold for developing regions that transition to undevelopment. Specifically, we contend that two of the three assumptions made in one of the earliest ICTD papers by Brewer et al. will no longer be true for such regions [2]: 1) the impact of Moore’s law is likely to slow or cease, not only due to inherent challenges of scaling today’s technology at prior rates, but also due to the increased relative cost of deploying new technology during increasingly hard economic times; and 2) favorable business environments are, in some regions, likely to be a temporary artifact of global surplus and trade, something that is widely expected to reverse [12, 13, 9].

3.2. Appropriate Technology

Because transportation costs will rise for undeveloping regions, sustainability in networking and ICT will need to become a significant focus. Sustainability in networking helps solve other societal sustainability issues, and the sustainability of networking itself will have to be prioritized. In particular, we advocate the adoption of the principles of “appropriate technology” [8, 18]; namely the design of networked systems that are a) simple, b) locally reproducible, c) composed of local materials and resources, d) easily repairable, e) affordable, and f) easily recyclable. Moreover, many of the resulting objectives are part of the networking canon: to build scalable networks that can be started and tested at a small scale with modest resources, resilient networks that remain useful under changing conditions and respond to pressures, modular networks separated into distinct elements that can be replaced at different scales and technological levels, and open networks that do not demand a certain system or set of components to function. It is however the case that in recent years ICTD research has far more effectively adhered to such maxims than the broader swath of networking research.

3.3. Complexity

In each of the case studies we considered in Section 2, we found that the complexity of the socioeconomic system in question was the root of much of the hardship. That is, each crisis trigger caused a series cascading economic failures. As today much of the economic infrastructure of developed economies relies upon networks and ICT more generally, we can play a direct role in decreasing complexity, or at the very least the impact of complexity. In a sense, our task is to help build resilience in the network of interactions between computing and non-computing systems throughout an economy, just as resilient and secure networks are designed to isolate faults and attacks. Such an effort would also be in line with the principles of Appropriate Technology outlined above.

A first step is to better understand the complexity of today’s networked systems. Ratnasamy began such an investigation by defining a complexity metric with which networked systems could be evaluated [16]; it would be valuable to extend this notion, apply it to better understand complex networked systems, and then expand the analysis to systems built upon them.

3.4. Transparency

One key way to help mitigate the ecological limits being faced is to better understand them, and the tools of networked systems—in particular sensor networks and cyber-physical systems—can be of particular value. Specifically, such systems can provide scientists, engineers, and policy-makers rich databases to enable analysis of local resources (both physical and virtual resources) and their flows. This might enable local communities to realize what substitutable resources they have locally that can replace remotely sourced inputs, and also potentially learn about the ability of their local bioregion to absorb pollution and waste flows in the form of natural sinks. This information can be valuable for energy sources as well (e.g. ICT can help a developing or undeveloping region better understand the rate at which they are depleting the forest for firewood or eroding the topsoil to grow biofuels, and can help understand how sinks like air pollution relate to it). However, such systems are challenging to build because of the scale required, the unreliability of the sources, and the way in which the system will have to operate (i.e. under challenging socioeconomic conditions), which argues for their near-term development.

3.5. Development During Undevelopment

As Burrell and Toyama discuss [4], it is not simply an open question of what ICT looks like in ICTD, but the notion of Development itself. In the context we discuss here, we believe that the notions of development considered most prominently by the ICTD community will naturally have to broaden. While there are researchers considering development in the context of sustainability and other constraints, development in the context of undeveloping regions facing limits to growth will have to be quite different indeed. While the thus-far unstated premise of our paper—that growth and thus development as it is currently perceived and measured is in the process of ending for many if not most regions—may seem like an ideological statement, we contend that our current growth paradigm is the same: implicitly accepted ideology. Indeed the science on the subject indicates that the current paradigm cannot continue, and not in the sense of ethics, but in the sense of hard ecological limits [13, 20, 14].

Thus with the necessary transition away from this paradigm—something that we as computer scientists will likely have little role in—we can embrace those alternative paradigms that have been developed over the last several decades that provide a more productive notion of development in a post-growth era. Specifically there exists a large body of work in the domain of Ecological Economics which we believe can and should inform such thinking, and aligns nicely with the objectives of Appropriate Technology discussed earlier.

4. Conclusions

It is our belief that ICTD research will become and needs to become more central to the mission of networking research if we are to appropriately respond to the converging issues we face. The broader networking community has yet to design systems to operate under such challenging conditions, and targeted to specific and fluctuating circumstances; on the other hand, the ICTD community deals with such challenges frequently and thus has much offer. Regardless of how the issues we explore in this paper develop, infusing the methodology and knowledge of ICTD research throughout the broader community can only yield benefits.

Principles of Terraforming

A few months back I started exploring the idea of terraforming. In this post I’d like to consider two important questions about it. First, what is terraforming, anyway? And second, why should we do it? Oddly enough, it seems to me that the second question is easier to answer than the first because even with a vague sense of what terraforming entails, it seems clear that there are many degraded ecosystems around us in the industrialized world today, ecosystems that could use what is conventionally termed “restoration”. (I hesitate to use the term “restoration” as most ecosystems will never be returned to what they once were before being overtaken by human interests, and since my goal isn’t to live apart from nature — there are way too many people on the planet for that — but rather to live among nature and with nature better than we have in the past.)

Why terraform?
I believe we should terraform the lands around us, however small or large. It seems to me that the first step to living with the natural world is to cultivate non-human life in it, and to come to better understand its natural patterns, its needs, and its constraints. This also seems, in the larger sense, to be a matter of self preservation, as it’s unlikely that global human society can keep on interacting with the natural world the way we have for the last couple of centuries without being felled by Limits to Growth.

Terraforming is a twin of conservation. That is, terraforming is a matter of us increasing what some ecological economists call “ecosystem services” while at the same time, through conservation, decreasing our footprints upon those same ecosystems.

What constitutes terraforming?
I’d like to define what I consider terraforming next. I know the term has all sorts of meanings, and in the past has most commonly been applied to the science fiction idea of transforming the environments of other planets to make them suitable for human inhabitation. The kind of terraforming I consider here is about small-scale ecosystem modification on Earth. Specifically, I’d like to lay out principles that might be worth following.

In presenting my thinking on this to Adam, he made the important point that principles can be of different sorts. Sometimes a list of principles defines hard and fast rules that place something in or out of some category (e.g., I could imagine this being like “well my technique of digging holes using a backhoe violates principle X of terraforming, so what I’m doing isn’t terraforming”). My aim isn’t that kind of list of principles, but rather one, as Adam put it, with scalar dimensions (e.g., the principles guide actions towards best practices, so there are better and worse instances of terraforming, relative to some local setting). In that sense, any action that changes the ecosystem in some way can be evaluated using the principles, and in this framing geoengineering is one kind of terraforming (one that does not adhere to the best practices very well). We could broadly term those efforts that adhere to the best practices as ecological terraforming.

One starting point is to consider two axes that might help separate, say, swale building from pumping sulfates into the stratosphere: 1) the duration of the action and 2) the human-derived energy flow to make that happen. It seems ecological terraforming is about kick starting natural cycles and systems that, once started, can continue on their own, so for 1) the duration is long and for 2) the human-derived energy flow is hopefully one-time. Conventional geoengineering schemes, from what I’ve seen, tend to be the other way around: 1) the duration is short (e.g., dump iron in one spot in the ocean, potentially sequester carbon, and that’s it; pump sulfates into the stratosphere, temporarily cool the planet) and 2) it’s all human energy required to make it have a positive effect. (The case could be made that, in a very indirect manner, conventional geoengineering schemes help kick start natural processes, since there’s a remote possibility that dumping iron into the ocean could revive a food web that had collapsed; this is why I don’t want to approach principles from a categorization perspective.)

I’ve been trying to tease this apart and come up with a set of guiding principles for terraforming. Some of these follow from the 12 permaculture principles, while others align with them but don’t really follow directly. Greer has suggested that one of the things that defines what he terms the ecotechnic crafts (a term that is a natural successor to Mumford’s -technic phases) is that it is about making subtle (maybe minimal?) changes to the web of connections that make up a local ecosystem to bring and/or keep things in balance (but with the intended effect).

My main concern is that the list as it stands might have false positives (i.e., questionable geoengineering schemes that are “good” by the principles) and false negatives (i.e., worthwhile terraforming actions that are in conflict with the principles). So please consider this a work in progress.

Terraforming principles.
1. Terraform for the long term: design and build expecting the terraforming to outlive everyone alive today.

2. Terraform to initiate natural ecosystem function and biogeochemical cycles: avoid actions that will require constant and ongoing human intervention.

3. Terraform degraded lands and immature ecosystems first: per Hemenway’s Gaia’s Garden (adapted from Drury and Nisbet), immature ecosystems are characterized by low biomass productivity, low organic matter, open mineral cycles, high nutrient loss, few microclimates, annual plants, low biodiversity, short/simple food chains, few ecological niches, few symbiotic relationships, low stability, and low complexity.

4. Terrform at the small scale: increase the scale of terraforming only when smaller-scale terraforming has been tried and has failed.

5. Prefer terraforming with natural power to human power, and human power to mechanical power: prefer digging a trench with running water to using a shovel to using a backhoe.

6. Prefer the maximal set, rather than the minimal set, of individual terraforming techniques to meet a goal: more techniques likely increase the resilience of the action.

7. Prefer terraforming actions that result in an ecosystem resilient to rapid and unpredictable changes in the local climate: plan for climate change and changes in land use patterns in the selection of plants and forms.


I also need to write up some examples of terraforming (and evaluate them under these principles), and describe how they can be used, but that’s for another time — maybe when I write about how the idea of programmable permaculture wasn’t intended to just be a strange computing analogy but actually an application of ideas from computer science to the challenges of terraforming. In that followup post I hope to also consider how Meadows’s list of places to intervene in a system can be applied to terraforming.

more minimalism

There’s a knock-knock joke that goes like this:

Knock-knock.

Who’s there?

Knock-knock.

Who’s there?

Knock-knock.

Who’s there?

Knock-knock.

Who’s there?

Philip Glass.

Which is a hilarious dart aimed at another minimalism.   But I found myself thinking of it upon looking at this recent NYTimes piece on minimal living, which sings the same old song.  This time, though, I noticed something new—although I think it’s been there in the minimalists’ writing all along.  Hill says:

My circumstances are unusual (not everyone gets an Internet windfall before turning 30), but my relationship with material things isn’t.

And I realized: no, your relationship with material things really is unusual, and it’s disingenuous to say otherwise.  Most people—whether we take ‘most’ historically or currently—don’t have a problem due to owning too many material things.  “Affluenza” is a malady of the affluent; that’s obvious.  But it never before struck me that part of the rhetorical trick of the minimalist is to present the affliction as normal.

Programmable Permaculture

There’s a cultural phenomenon, one that has been growing for the past decade, of hobbyist hackers exemplified by Make Magazine and TechShop. These hackers want to have the experience of building something in the physical world while still applying the tools and techniques of computing. With the rise of open hardware platforms like Arduino—even whole systems like the Raspberry Pi for $25—it’s surprisingly affordable for people to program their own electronics.

The key to design when working on such projects is to decompose a problem into its constituent actions, to figure out what can be done by the programmable hardware vs. what must be done using other (e.g., more conventionally mechanical) components, and then to assemble the pieces into a working whole. While I can’t say I have any deep experience working on such projects, for some time I’ve been wondering whether the same ideas can be applied in a direction of more interest and perhaps of more importance.

How can we solve a problem (in a garden, say), with permaculture tools, by decomposing the problem and coming up with a set of interlocking pieces that solves it? Framing the problem in this way is very much applying an engineering mindset, something that might irk those who insist on thinking holistically about any and all ecological settings. (And I can relate to that sentiment, because too much has been done in engineering and science more broadly to stop holistic thinking and to employ scientific reductionism in its place.)

But for the moment I want to consider something small scale: employing the vocabulary and tools of permaculture to specific tasks in a garden. Here are the stated principles of permaculture:

  1. Observe and interact: By taking time to engage with nature we can design solutions that suit our particular situation.
  2. Catch and store energy: By developing systems that collect resources at peak abundance, we can use them in times of need.
  3. Obtain a yield: Ensure that you are getting truly useful rewards as part of the work that you are doing.
  4. Apply self-regulation and accept feedback: We need to discourage inappropriate activity to ensure that systems can continue to function well.
  5. Use and value renewable resources and services: Make the best use of nature’s abundance to reduce our consumptive behavior and dependence on non-renewable resources.
  6. Produce no waste: By valuing and making use of all the resources that are available to us, nothing goes to waste.
  7. Design from patterns to details: By stepping back, we can observe patterns in nature and society. These can form the backbone of our designs, with the details filled in as we go.
  8. Integrate rather than segregate: By putting the right things in the right place, relationships develop between those things and they work together to support each other.
  9. Use small and slow solutions: Small and slow systems are easier to maintain than big ones, making better use of local resources and producing more sustainable outcomes.
  10. Use and value diversity: Diversity reduces vulnerability to a variety of threats and takes advantage of the unique nature of the environment in which it resides.
  11. Use edges and value the marginal: The interface between things is where the most interesting events take place. These are often the most valuable, diverse and productive elements in the system.
  12. Creatively use and respond to change: We can have a positive impact on inevitable change by carefully observing, and then intervening at the right time.

I don’t know about you, but while I agree with this list, it’s all a little vague. And so what I’d like to look at is specific techniques that have broadly become part of the permaculture bag of tricks that somewhat adhere to this thinking.

To make the goal concrete, let’s focus on one question: how can a gardener create different sorts of microclimates of soil, air, and water for the diversity of plants one might want to include in a garden? While I could have considered other goals like water purification, fertilization, composting, water transport, etc. I’ve found myself trying to figure out microclimates a lot lately so it seems like a good place to start. It seems to me that many challenges I’ve run into while gardening have to do with the environment not being right for what I’m trying to grow, something that’s inevitable given that most of the food-bearing crops we eat today are not native to the places we live.

I’m often reminded of Sepp Holzer’s citrus gardens in the Alps as a sign that it’s possible to do amazing things with microclimates, but very few people have Holzer’s level of skill and experience. This is where programmable permaculture comes in. To make the analogy concrete, here the hardware is permaculture, which is capable of being used to do perform certain actions towards a goal, and the software is the creative combination of instructions for the hardware to achieve that goal. The certain actions the hardware can execute is its instruction set, and usually hardware is relatively minimalist (and the challenge is to make it complete at the same time), so it’s the combination of steps that makes it powerful. In addition to the microclimate aspect we want to adjust (soil, air, water, etc.) there’s the question of scale—how big is the microclimate? Are the techniques that help when building an herb spiral the same as when building an impoundment lake? That is, is there a subroutine in common between the two?

Let’s say we’re trying to grow avocados in a flat garden in a suboptimal climate. Avocados (the tasty cultivars, anyway) require well-drained fertile soil, nearly zero days of frost in the winter and relatively warm summer days, no shallow-root competition, and lots of direct sun. While we’re probably not going to be growing avocados in Portland, Maine (anytime soon, that is), we might be able to grow them in Portland, Oregon with the right microclimate. So let’s decompose it:

Soil: the soil in the Willamette Valley is plenty fertile, though throughout the winter it’s probably too wet for an Avocado tree. Here we might apply the principle of self-regulation, and dig a shallow French drain near the tree, and direct the water from it to a pond. Since the garden is flat in this example, the tree would have to be on a raised bed.

Frost: Portland has over 30 days of frost a year and even a few days with highs below freezing annually. (To give you a sense of the challenge that presents, consider that the California Master Gardener Handbook lists Santa Cruz County as the furthest North one can reliably grow avocados, and Santa Cruz gets something like 3 days of mild frost per year.) Here we clearly want to catch and store energy. The key is that the average (over a 24 hour period) is typically above freezing, and so buffers are key. We want to store a lot of heat and release it slowly, and conveniently water has the highest specific heat capacity of any common substance. That suggests that digging a pond near the tree—perhaps the same pond that was used for drainage—would help store heat during the day and re-radiate it at night. Add warm wastewater from a house to the pond and we apply the principle “produce no waste” while giving the tree-pond system a margin of safety for those days that don’t go above freezing. Stones placed in and around the tree and pond can add to the pond’s heat buffering.

Sun: The Pacific Northwest isn’t known for its sunshine. It’s likely that the directly incident rays in Portland would be insufficient for a tropical / sub-tropical tree like an avocado. Conveniently, water reflects light, and by placing the pond at the correct angle for the winter sun, we can provide a bit of extra sunshine to the tree via pond reflection. But what if the sky is just gray and the sun’s rays diffuse? While there isn’t much we can do, we can build a small parabolic reflector that redirects the sun’s rays at the tree from another spot in the garden. (One technique I’ve heard of is to pick up a discarded satellite dish and cover it in something reflective like aluminum foil.)

The other microclimate needs—such as warm summer days—are probably already met here.

While this application of principles was fun, it wasn’t as, well, programmable as I would have liked. Ideally it’d be possible to take a setting, describe the constraints / objectives within some dimensions, and then directly apply techniques that are derived from the principles to achieve the goal. In another post I’ll try to develop what we might consider an instruction set for permaculture and also, separately, what might differentiate permaculture from geoengineering.

Internet vs. Travel

A few months back, I was asked the following question via email:

I am trying to find out how much power will be used, both in my home and on the systems computer hubs, if I were to use Skype for and hour and a half to people who live 20 miles away. Is it better than driving?

There are a few variables (whether the computer would be on or not if Skype wasn’t going to be in use, etc.). But one of the findings of a study I did a little over a year ago was that Skype or similar video chat software uses (in terms of its share of the Internet’s infrastructure energy consumption) about 65 MJ / hour, so here, for 1.5 hours, that’d be 97.5 MJ. You could also add in the power to run the two machines (probably laptops), which would be about 40W * 2 * 5400 seconds = 0.43 MJ, which is negligible by comparison. So let’s say 98 MJ for the Skype call in total. Gasoline has a primary energy of about 132 MJ / gallon, and the drive would probably consume about 1.5 gallons of gas, using a total of 198 MJ.

So it turns out that Skype would indeed save energy if we compare the electricity up front with the gasoline’s primary energy. There is a more complex question here about how to factor in the primary energy used to derive the electricity, and that varies widely by country and source. As a discussed a while back about the idea of transformity, we have to root our energy discussions in a common underlying unit. Odum’s solution for this was to use seJ, or solar-equivalent Joules, but it’s a bit cumbersome to work that out for everything. So we might scale up Skype’s contribution by a factor of 2x or 3x (roughly) to account for this. Even still, Skype would use roughly the same energy as driving, and if you were to consider going further than 20 miles then it’s definitely the case that video chat would use less energy.

So from a somewhat holistic energy perspective, it’s generally better to use electrically driven options rather than oil-based options because the electricity can be sourced in many ways that are more sustainable (and while they’re not by and large today, they eventually can be) and oil and fossil fuels generally are depleting rapidly and impacting the climate.

There is however the question of complexity limits. The Internet is a complex system, as I explored in a study of the Internet’s dependencies. And as Greer and others have observed, complexity limits can make a complex system unviable long before energy limits do. That said, it’s hard to say which of the two systems—the global petrochemical industry or the global Internet—is more complex, and so for the time being my inclination is to move bits rather than move atoms.

Free Services

A while back I had considered free energy as it exists in modern industrial society. Today I want to consider free services provided by nature, but that are ignored for what they are, especially in the context of a long-running trend that is finally getting notice in the tech-centric media: the tension between automation and employment. Specifically, I’ve been trying to understand what these trends say about how we conceive of our society and the ecosystem around it.

This post from a few months back reminded me about how proponents of “advanced” farming techniques haven’t given up, and are still pushing their expensive wares. Despite the various claims about the energy, environmental, and human benefits of vertical farms and the like, part of the issue left unaddressed is actually standard fare for ecological economics. That is, I think there’s something deeper and simpler to explain why vertical farming always has proponents: the economic model in question. A common ecological-economic observation is that the services rendered by nature aren’t quantified in economic terms so they can’t be compared with replacement services created by human-built systems. Vertical “plantscrapers”, fish farms, water purification, fertilization, etc. fall into this category. As observed at the link above:

If a machine were invented that scrubbed carbon from the atmosphere and turned it into useful food, construction materials, animal feedstocks, and fibers, all while rebuilding topsoil, it would be on the cover of every tech magazine in the world and its inventor would be a celebrity millionaire. Yet I’ve never seen a tree on the cover of Wired.

But it’s not only trees that provide such useful services that are ignored. What are some others, and how could they be reframed to be a high-tech “green” technology? In other words, what other things nature does for free would be hailed as a breakthrough if only created by a human? I’d like to consider those questions in a future post, but for now, how does this fit into the question of automation and the trends that seem to most excite techno-optimists?

Kevin Kelly, who I find to be among more the thoughtful of techno-optimists, seems to acknowledge in a recent article (as it happens, in Wired magazine) that yes there are physical limits we’re facing, and we’ll navigate those currents (and many more) through increased used of smart robots which will replace the tedious, dangerous, and expensive things that are currently done by human hands.

I think back to the thoroughly-cynical but not incorrect Sevareid’s Law: The chief cause of problems is solutions. Kelly, it seems, is saying exactly this (without actually saying it): that it’s right and proper that people should continue to find new things to do as automation replaces the things they used to do, even as those new things are really largely to fix the problems created by replacing human work with automation. While I’m not really qualified to speak on philosophical matters, it seems Kelly is wholeheartedly endorsing the idea that humanity should embrace its role as Sisyphus, though I’m pretty sure he doesn’t think of it that way.

But here’s again the problem with the techno-fix approach: if we’re facing just engineering problems that will require engineering solutions (in the immortal words of Exxon CEO Rex Tillerson), then we ignore the the fact that human misery as a result of backbreaking labor has much more to do with imbalances in the economic system and exploitation of people than it does with the availability or lack of technology (i.e. an “engineering solution”). This is evidenced by the societies that have managed to have relatively high levels of human wellbeing (high autonomy, literacy, health, etc.) while also staying close to the ground, as it were (Kerala comes to mind, though I’m sure there are better examples).

And this brings us back to the question about the services nature provides for us. It seems that in many ways our struggle as an industrial society is almost a rebellion against the very physical, chemical, and biological forces around us. This almost defines the modern industrial system, and it’s often celebrated (immortalized in sayings like Clarke’s—”any sufficiently advanced technology is indistinguishable from magic”—and Kay’s—”technology is anything that was invented after you were born”).

I think there are three ideas I’m trying to convey here, none of which are new:
1) that the primary blindspot in new technology is that it is pursued not only for its own sake, but without considering the vast invisible support system underneath that is fundamentally rooted in what the ecosystem provides for us,
2) that in a world in which people are even further distanced from the ecosystem—via automation or economics or otherwise—people will perpetuate a shortsighted approach to human and non-human affairs, and
3) that in this thinking it is the struggle itself against nature and against other human beings that almost defines the value of a pursuit.

It’s in this spirit that vertical farms are proposed: basic functions that the ecosystem provides are forgotten (e.g. work done by life in natural soils); part of the allure is that satisfaction (and sometimes recognition) comes from the immensity of the struggle itself against, in this case, gravity (not to mention basic physical issues like shadows); and as people are further distanced from the ecosystem such proposals will seem increasingly worthwhile.

I think that permaculture, among other systems, works to correct some of these mistakes, but, significantly, not all of them. To begin with, one of its primary tools is to take a Jujutsu-approach to ecosystems—to let them do their work on our behalf in the way that they naturally would. As commonly practiced permaculture also acknowledges the ecosystem services that underlie the systems the permaculture designer is building. However, it’s this last issue that I think hasn’t really been addressed or resolved yet—how to make this new kind of permaculture-oriented struggle (likely as meaningless, in the sense of Camus, as the one that it seeks to replace) feel more worthwhile to people and societies who have, for a very long time, defined themselves by a “progress”-driven struggle against nature. It’s the challenge of replacing this long-held drive to commodify not only nature, but also other people in the process, that will require not only thought, but action that seems to not yet be a focus of those thinking about these issues today.
