Resilience Thinking

by Rob Hopkins
Resilience; “the capacity of a system to absorb disturbance and reorganize while undergoing change, so as to retain essentially the same function, structure, identity and feedbacks”.


Resilience Thinking. Why ‘resilience thinking’ is a crucial missing piece of the climate-change jigsaw and why resilience is a more useful concept than sustainability.


In July 2009, UK Secretary of State for Energy and Climate Change Ed Miliband unveiled the government’s UK Low Carbon Transition Plan, a bold and powerful statement of intent for a low-carbon economy in the UK. It stated that by 2020 there would be a five-fold increase in wind generation, feed-in tariffs for domestic energy generation, and an unprecedented scheme to retrofit every house in the country for energy efficiency. In view of the extraordinary scale of the challenge presented by climate change, I hesitate to criticise steps in the right direction taken by government. There is, though, a key flaw in the document, which also appears in much of the wider societal thinking about climate change. This flaw is the attempt to address the issue of climate change without also addressing a second, equally important issue: that of resilience.

The term ‘resilience’ is appearing more frequently in discussions about environmental concerns, and it has a strong claim to actually being a more useful concept than that of sustainability. Sustainability and its oxymoronic offspring sustainable development are commonly held to be a sufficient response to the scale of the climate challenge we face: to reduce the inputs at one end of the globalized economic growth model (energy, resources, and so on) while reducing the outputs at the other end (pollution, carbon emissions, etc.). However, responses to climate change that do not also address the imminent, or quite possibly already passed, peak in world oil production do not adequately address the nature of the challenge we face.

Let’s take a supermarket as an example. It may be possible to increase its sustainability and to reduce its carbon emissions by using less packaging, putting photovoltaics on the roof and installing more energy-efficient fridges. However, resilience thinking would argue that the closure of local food shops and networks that resulted from the opening of the supermarket, as well as the fact that the store itself only contains two days’ worth of food at any moment – the majority of which has been transported great distances to get there – has massively reduced the resilience of community food security, as well as increasing its oil vulnerability. One extreme, but relevant, example of where sustainability thinking falls short was Tesco’s recent ‘Flights for Lights’ promotion, where people were able to gain air miles when they purchased low-energy light bulbs!

Some people believe that we can move from our current ‘high carbon’ model, where goods are transported at great distances, to a ‘low carbon’ information economy, where it is ideas that are exchanged rather than goods, and where we operate in a virtual world with few impacts. Yet such an economy still depends on fossil fuels: to power the vast internet servers as we check our morning emails, not to mention the breakfast we eat and the coffee we drink that continue to be sourced from far and wide, often with a disastrous impact on the local food systems that would have supported us in the past. Despite the temptation to believe otherwise, we still operate in the physical world with very real and pressing energy and resource constraints.

The concept of resilience emerged from within the ecological sciences as a way of looking at why some systems collapse when they encounter shock, and some don’t. The insights gleaned now offer a very useful overview for determining how systems can adapt and thrive in changing circumstances. Resilience within communities, for example, depends upon;”

  • Diversity: a broader base of livelihoods, land use, enterprise and energy systems than at present
  • Modularity: not advocating self-sufficiency, but rather an increased self-reliance; with ‘surge protectors’ for the local economy, such as local food production and decentralised energy systems
  • Tightness of feedbacks: bringing the results of our actions closer to home, so that we cannot ignore them
A recent report by the think tank DEMOS, Resilient Nation, raised the question, “Resilient to what?” Are we building resilience in the face of peak oil and climate change, or of terrorism and pandemics? While it is clearly not an either/or situation, I would argue strongly that peak oil and climate change are so far-reaching and destabilizing that we really must give them precedence, the solutions that arise being markedly different from addressing terrorism or pandemics. But what would this kind of resilience thinking look like in practice?

For many years, those writing and campaigning on relocalization have argued that it is a good idea because it produces a better, more equitable economy. Now, as the potential impacts of peak oil and climate change become clearer, an additional and very strong argument has emerged: that as the net energy underpinning society inevitably contracts, so the focus of our economies and our daily lives will inexorably shift, at least in terms of manufacturing and trade, from the global to the local.

It requires a huge amount of cheap oil thundering around the superhighways and shipping lanes of the world to bring to our shops the things we now feel we need, much of which we would have grown or made ourselves not all that long ago. But creating a different way of doing things takes time, resources and proactive and creative design.

Often, climate-change thinking doesn’t question the notion that higher rates of consumption lead to individual happiness – it focuses rather on low-carbon ways of making the same consumer goods. Yet as we enter the world of volatile oil prices, resource constraints, and the need to situate ourselves more within the local economy than the global one, we will need to link satisfaction and happiness to other less tangible things like community, meaningful work, skills and friendships.

When I give talks on this subject, there are always some who interpret the concept of increasing localization to mean that building resilience in the West – increasing national food security, rebuilding local manufacturing and so on – will by necessity lead to increased impoverishment in the developing world. I don’t believe this to be the case. Will the developing world be lifted out of poverty by continuing to dismantle its own food resilience and becoming increasingly dependent on global trade, which is itself massively dependent on the cheap oil we can no longer rely on? Is the way out of poverty really an increasing reliance on the utterly unreliable? Rather than communities meeting each other as unskilled, unproductive, dependent and vulnerable settlements, they would meet as skilled, abundantly productive, self-reliant and resilient communities. It is a very different quality of relationship, and one that could be hugely beneficial to both.

In any event, work by people such as Mike Davis in his book Late Victorian Holocausts shows how the impact of famine was enormously magnified by the forced introduction of India into the international money/cash-crop nexus. As Amartya Sen has shown, famine occurs more from the way in which food is distributed, and inequality, than from food shortage. Even that analysis now needs to be revisited from a ‘resilience’ perspective. Over the last few years we’ve started to see clear impacts of tying the developing world into global commercial food webs, as food prices rose in step with oil and fertilizer prices. In fact, I’d argue that tying developing-world food producers into the globalized system leads to their exposure to both food and money shortages.

The need to cut carbon emissions is even more urgent than the government’s Transition Plan acknowledges. NASA scientist James Hansen, one of the world’s leading climate scientists, now argues that we have already passed the climate tipping point at our current level of 387ppm, when the safe level of carbon in the atmosphere is at most 350ppm. While the UK government argues that we need to stay below 450ppm, it is clear that even that is a huge ask. If you were to step outside your front door today and ask the first ten people you met what your town or city might look like in ten years’ time if it began today to cut its emissions by 9% a year starting today, I imagine most people would say something between the Flintstones and Mad Max! We have a paucity of stories that articulate what a lower-energy world might sound like, smell like, feel like and look like. What is hard, but important, is to be able to articulate a vision of a post-carbon world so enticing that people leap out of bed every morning and put their shoulders to the wheel of making it happen.

Resilience thinking can inspire a degree of creative thinking that might actually take us closer to solutions that will succeed in the longer term. Resilient solutions to climate change might include community-owned energy companies that install renewable energy systems in such a way as to generate revenue to resource the wider relocalization process; the building of highly energy-efficient homes that use mainly local materials (clay, straw, hemp), thereby stimulating a range of potential local businesses and industries; the installation of a range of urban food production models; and the re-linking of farmers with their local markets. By seeing resilience as a key ingredient of the economic strategies that will enable communities to thrive beyond the current economic turmoil the world is seeing, huge creativity, reskilling and entrepreneurship are unleashed.

The Transition Movement is a rapidly growing, ‘viral’ movement, which began in Ireland and is now under way in thousands of communities around the world. Its fundamental premise is that a response to climate change and peak oil will require action globally, nationally, and at the scale of local government, but it also needs vibrant communities driving the process, making unelectable policies electable, creating the groundswell for practical change at the local level.
It explores the practicalities of building resilience across all aspects of daily life. It catalyses communities to ask, “How are we going to significantly rebuild resilience in response to peak oil and drastically reduce carbon emissions in response to climate change?”

By putting resilience alongside the need to reduce carbon emissions, it is catalyzing a broad range of initiatives, from Community Supported Agriculture and garden-share schemes to local food directories and new Farmers’ Markets. Some places, such as Lewes and Totnes, have set up their own energy companies, in order to resource the installation of renewable energy. The Lewes Pound, the local currency that can only be spent in Lewes, recently expanded with the issuing of new £5, £10 and £20 notes. Stroud and Brixton are set to do the same soon.
The Scottish government is using its Climate Challenge Fund to fund Transition Scotland Support, seeing Transition initiatives as a key component of the country’s push on climate change (and thanks also to that fund, a number of Transition initiatives have received substantial financial support: for example, Transition Forres received £184,000 and has become a real force for local resilience-building). In England, Somerset and Leicestershire County Councils have both passed resolutions committing themselves to support local Transition initiatives. What underpins these responses is the idea that meeting our climate emissions responsibilities and preparing proactively for the end of the age of cheap oil can either be seen as enormous crises, or as tremendous opportunities.

Capitalism as if the World
 MattersIt is clear, as Jonathon Porritt argues in Living Within Our Means, that attempting to get out of the current recession with the thinking that got us into it in the first place (unregulated banking, high levels of debt, high-carbon lifestyles) will get us into a situation that we simply cannot win. A friend of mine who works as a sustainability consultant in the North West talks of a meeting he had with a leading local authority there. Having read their development plan for the next twenty years, he told them, “Your Plan is based on three things: building cars, building airplanes and the financial services sector. Do you have anything else up your sleeves?” As John Michael Greer says, we’re in danger of turning what could still be a soluble problem into an insoluble predicament. Transition is an exploration of what we need to have ‘up those sleeves’, an optimistic exploration of the practicalities of relocalisation, creating, as Jeremy Leggett puts it, “scaleable microcosms of hope”.

However, resilience is not just an outer process: it is also an inner one, of becoming more flexible, robust and skilled. Transition initiatives try to promote this through offering skills-sharing, building social networks and creating a shared sense of this being a historic opportunity to build the world anew.

Navigating a successful way through climate change and peak oil will require a journey of such bravery, commitment and vision that future generations will doubtless tell stories and sing great songs about it. But as with any journey, having a clear idea of where you are headed and the resources that you have at your disposal is essential in order to most skilfully maximize your chances of success. If we leave resilience thinking out, we may well end up an extremely long way from where we initially thought we were headed.

Twenty Years Later: Tipping Points Near on Global Warming

Published on Tuesday, June 24, 2008 by The Huffington Post

Twenty Years Later: Tipping Points Near on Global Warming
Dr. James Hansen by James Hansen

[Monday] I testified to Congress about global warming, 20 years after my June 23, 1988 testimony, which alerted the public that global warming was underway. There are striking similarities between then and now, but one big difference.

Again a wide gap has developed between what is understood about global warming by the relevant scientific community and what is known by policymakers and the public. Now, as then, frank assessment of scientific data yields conclusions that are shocking to the body politic. Now, as then, I can assert that these conclusions have a certainty exceeding 99 percent.

The difference is that now we have used up all slack in the schedule for actions needed to defuse the global warming time bomb. The next president and Congress must define a course next year in which the United States exerts leadership commensurate with our responsibility for the present dangerous situation.

Otherwise it will become impractical to constrain atmospheric carbon dioxide, the greenhouse gas produced in burning fossil fuels, to a level that prevents the climate system from passing tipping points that lead to disastrous climate changes that spiral dynamically out of humanity’s control.

Changes needed to preserve creation, the planet on which civilization developed, are clear. But the changes have been blocked by special interests, focused on short-term profits, who hold sway in Washington and other capitals.

I argue that a path yielding energy independence and a healthier environment is, barely, still possible. It requires a transformative change of direction in Washington in the next year.

On June 23, 1988 I testified to a hearing, organized by Senator Tim Wirth of Colorado, that the Earth had entered a long-term warming trend and that human-made greenhouse gases almost surely were responsible. I noted that global warming enhanced both extremes of the water cycle, meaning stronger droughts and forest fires, on the one hand, but also heavier rains and floods.

My testimony two decades ago was greeted with skepticism. But while skepticism is the lifeblood of science, it can confuse the public. As scientists examine a topic from all perspectives, it may appear that nothing is known with confidence. But from such broad open-minded study of all data, valid conclusions can be drawn.

My conclusions in 1988 were built on a wide range of inputs from basic physics, planetary studies, observations of on-going changes, and climate models. The evidence was strong enough that I could say it was time to “stop waffling.” I was sure that time would bring the scientific community to a similar consensus, as it has.

While international recognition of global warming was swift, actions have faltered. The U.S. refused to place limits on its emissions, and developing countries such as China and India rapidly increased their emissions.

What is at stake? Warming so far, about two degrees Fahrenheit over land areas, seems almost innocuous, being less than day-to-day weather fluctuations. But more warming is already “in the pipeline,” delayed only by the great inertia of the world ocean. And climate is nearing dangerous tipping points. Elements of a “perfect storm,” a global cataclysm, are assembled.

Climate can reach points such that amplifying feedbacks spur large rapid changes. Arctic sea ice is a current example. Global warming initiated sea ice melt, exposing darker ocean that absorbs more sunlight, melting more ice. As a result, without any additional greenhouse gases, the Arctic soon will be ice-free in the summer.

More ominous tipping points loom. West Antarctic and Greenland ice sheets are vulnerable to even small additional warming. These two-mile-thick behemoths respond slowly at first, but if disintegration gets well under way, it will become unstoppable. Debate among scientists is only about how much sea level would rise by a given date. In my opinion, if emissions follow a business-as-usual scenario, sea level rise of at least two meters is likely within a century. Hundreds of millions of people would become refugees, and no stable shoreline would be reestablished in any time frame that humanity can conceive.

Animal and plant species are already being stressed by climate change. Species can migrate in response to movement of their climatic zone, but some species in polar and alpine regions will be pushed off the planet. As climate zones move farther and faster, climate change will become the primary cause of species extinction. The tipping point for life on the planet will occur when so many interdependent species are lost that ecosystems collapse.

The shocking conclusion, documented in a paper2 I have written with several of the world’s leading climate experts, is that the safe level of atmospheric carbon dioxide is no more than 350 ppm (parts per million), and it may be less. Carbon dioxide amount is already 385 ppm and rising about 2 ppm per year. Shocking corollary: the oft-stated goal to keep global warming less than two degrees Celsius (3.6 degrees Fahrenheit) is a recipe for global disaster, not salvation.

These conclusions are based on paleoclimate data showing how the Earth responded to past levels of greenhouse gases and on observations showing how the world is responding to today’s carbon dioxide amount. The consequences of continued increase of greenhouse gases extend far beyond extermination of species and future sea level rise.

Arid subtropical climate zones are expanding poleward. Already an average expansion of about 250 miles has occurred, affecting the southern United States, the Mediterranean region, Australia and southern Africa. Forest fires and drying-up of lakes will increase further unless carbon dioxide growth is halted and reversed.

Mountain glaciers are the source of fresh water for hundreds of millions of people. These glaciers are receding world-wide, in the Himalayas, Andes and Rocky Mountains. They will disappear, leaving their rivers as trickles in late summer and fall, unless the growth of carbon dioxide is reversed.

Coral reefs, the rainforest of the ocean, are home to one-third of the species in the sea. Coral reefs are under stress for several reasons, including warming of the ocean, but especially because of ocean acidification, a direct effect of added carbon dioxide. Ocean life dependent on carbonate shells and skeletons is threatened by dissolution as the ocean becomes more acid.

Such phenomena, including the instability of Arctic sea ice and the great ice sheets at today’s carbon dioxide amount, show that we have already gone too far. We must draw down atmospheric carbon dioxide to preserve the planet we know. A level of no more than 350 ppm is still feasible, with the help of reforestation and improved agricultural practices, but just barely ­ time is running out.

The steps needed to halt carbon dioxide growth follow from the size of fossil carbon reservoirs. Coal towers over oil and gas. Phase out of coal use except where the carbon is captured and stored below ground is the primary requirement for solving global warming.

Oil is used in vehicles, where it is impractical to capture the carbon. But oil is running out. To preserve our planet we must also ensure that the next mobile energy source is not obtained by squeezing oil from coal, tar shale or other fossil fuels.

Fossil fuel reservoirs are finite, which is the main reason that prices are rising. We must move beyond fossil fuels eventually. Solution of the climate problem requires that we move to carbon-free energy promptly.

Special interests have blocked transition to our renewable energy future. Instead of moving heavily into renewable energies, fossil companies choose to spread doubt about global warming, as tobacco companies discredited the smoking-cancer link. Methods are sophisticated, including disguised funding to shape school textbook discussions.

CEOs of fossil energy companies know what they are doing and are aware of long-term consequences of continued business as usual. In my opinion, these CEOs should be tried for high crimes against humanity and nature. If their campaigns continue and “succeed” in confusing the public, I anticipate testifying against relevant CEOs in future public trials.

Conviction of ExxonMobil and Peabody Coal CEOs will be no consolation, if we pass on a runaway climate to our children. Humanity would be impoverished by ravages of continually shifting shorelines and intensification of regional climate extremes. Loss of countless species would leave a more desolate planet.

If politicians remain at loggerheads, citizens must lead. We must demand a moratorium on new coal-fired power plants. We must block fossil fuel interests who aim to squeeze every last drop of oil from public lands, off-shore, and wilderness areas. Those last drops are no solution. They provide continued exorbitant profits for a short-sighted self-serving industry, but no alleviation of our addiction or long-term energy solution.

Moving from fossil fuels to clean energy is challenging, yet transformative in ways that will be welcomed. Cheap, subsidized fossil fuels engendered bad habits. We import food from halfway around the world, for example, even with healthier products available from nearby fields. Local produce would be competitive if not for fossil fuel subsidies and the fact that climate change damages and costs, due to fossil fuels, are also borne by the public.

A price on emissions that cause harm is essential. Yes, a carbon tax. Carbon tax with 100 percent dividend is needed to wean us off fossil fuel addiction. Tax and dividend allows the marketplace, not politicians, to make investment decisions.

Carbon tax on coal, oil and gas is simple, applied at the first point of sale or port of entry. The entire tax must be returned to the public, an equal amount to each adult, a half-share for children. This dividend can be deposited monthly in an individual’s bank account.

Carbon tax with 100 percent dividend is non-regressive. On the contrary, you can bet that low and middle income people will find ways to limit their carbon tax and come out ahead. Profligate energy users will have to pay for their excesses.

Demand for low-carbon high-efficiency products will spur innovation, making our products more competitive on international markets. Carbon emissions will plummet as energy efficiency and renewable energies grow rapidly. Black soot, mercury and other fossil fuel emissions will decline. A brighter, cleaner future, with energy independence, is possible.

Washington likes to spend our tax money line-by-line. Swarms of high-priced lobbyists in alligator shoes help Congress decide where to spend, and in turn the lobbyists’ clients provide “campaign” money.

The public must send a message to Washington. Preserve our planet, creation, for our children and grandchildren, but do not use that as an excuse for more tax-and-spend. Let this be our motto: “One hundred percent dividend or fight! No more alligator shoes!”

The next president must make a national low-loss electric grid an imperative. It will allow dispersed renewable energies to supplant fossil fuels for power generation. Technology exists for direct-current high-voltage buried transmission lines. Trunk lines can be completed in less than a decade and expanded analogous to interstate highways.

Government must also change utility regulations so that profits do not depend on selling ever more energy, but instead increase with efficiency. Building code and vehicle efficiency requirements must be improved and put on a path toward carbon neutrality.

The fossil-industry maintains its stranglehold on Washington via demagoguery, using China and other developing nations as scapegoats to rationalize inaction. In fact, we produced most of the excess carbon in the air today, and it is to our advantage as a nation to move smartly in developing ways to reduce emissions. As with the ozone problem, developing countries can be allowed limited extra time to reduce emissions. They will cooperate: they have much to lose from climate change and much to gain from clean air and reduced dependence on fossil fuels.

We must establish fair agreements with other countries. However, our own tax and dividend should start immediately. We have much to gain from it as a nation, and other countries will copy our success. If necessary, import duties on products from uncooperative countries can level the playing field, with the import tax added to the dividend pool.

Democracy works, but sometimes churns slowly. Time is short. The 2008 election is critical for the planet. If Americans turn out to pasture the most brontosaurian congressmen, if Washington adapts to address climate change, our children and grandchildren can still hold great expectations.

Dr. James Hansen directs the NASA Goddard Institute for Space Studies in New York City and is Adjunct Professor of Earth Sciences at Columbia University’s Earth Institute. Since the mid-1970s, Dr. Hansen has focused on studies and computer simulations of the Earth’s climate, for the purpose of understanding the human impact on global climate. He is best known for his testimony on climate change to Congress in the 1980s that helped raise broad awareness of the global warming issue. In recent years Dr. Hansen has drawn attention to the danger of passing climate tipping points, producing irreversible climate impacts that would yield a different planet from the one on which civilization developed. Dr. Hansen disputes the contention, of fossil fuel interests and governments that support them, that it is an almost god-given fact that all fossil fuels must be burned with their combustion products discharged into the atmosphere. Instead Dr. Hansen has outlined steps that are needed to stabilize climate, with a cleaner atmosphere and ocean, and he emphasizes the need for the public to influence government and industry policies.
