The seminal book The Limits to Growth by Donella Meadows and colleagues was a first attempt to make a world model that integrated environment, economics, population, and industrial pollution. Without drastic changes to curb human population growth, consumption of non-renewable resources and industrial effluence, the model scenario projected a collapse of the world social-industrial system, because physically it is not possible to keep growing on a finite planet.  This important message spurred many people in the environmental sciences, but was largely ignored, or worse ridiculed, by the dominant economic and political leaders.  Perhaps their work was too pessimistic (although some could say realistic) and called for change for which society was not yet ready.

My co-authors and I  feel their message was interpreted incorrectly.  The restrictions imposed by The Limits to Growth do not entail stagnation and strife but rather give us an opportunity for new priorities, greater equity, and greater well-being.  Living within the limits can offer agreeable, pleasant, even thriving and wonderful living conditions.

Therefore we have written a book, which shows that following nature provides guidance and pathways to Flourishing within Limits to Growth.

People today are confronted with a number of very serious problems: poverty, increased inequalities among countries and people, refugees, regional conflicts and civil wars, global climate change, accelerating exploitation of the global non-renewable and renewable resources, rapid land use change and urbanization, and increased emissions of harmful chemicals into the environment. History has shown us that we cannot solve these problems using traditional methods based on short-sighted economic growth.

Additionally, we know from natural laws that continuous growth in a finite environment is not possible. How can we ensure sustainable development for society on Earth? It would be possible by imitating the system that understands how to sustain long-term development: to learn from nature and follow nature’s way. Nature shifts from quantitative biomass growth when the resources become limiting to qualitative development by increasing resource use efficiency, in terms of both improved network connectivity and information on process regulation and feedbacks. The two main ecosystem functions, flow of energy and transfer of nutrients, are accomplished by renewable energy and complete recycling of the needed elements.  Nature also originated and perfected the use the 3Rs: Reduce, Reuse, and Recycle.

Our book employs a global model to experiment with applying these properties of nature in society. Using global statistics, the model considers how the development will change if:

  • A revenue-neutral, resource-based Pigovian tax is increased significantly and along with commensurate tax reduction to enhance recycling and application of renewable energy
  • We increase investment in education, innovation, and research significantly to raise the level of understanding by the population and to develop new progressive ideas to address our global problems.
  • We increase pollution abatement considerably to reduce its negative impacts on our health, nature, and production.
  • We increase aid from the developed to the developing countries to 0.8% of GNP, which would enhance the cooperation among countries, reduce poverty and population growth and thereby also the number of refugees. In this context, it is important that the aid is given as support to education, health care, and family planning and not at all as military aid.

flourishingbookThe model calculations show that it is possible to obtain a win-win situation, where both industrialized and developing nations can achieve a better standard of living – the developing countries mostly quantitatively and the developed countries mostly qualitatively. The calculations are compared with scenarios based on “business as usual” practices. The business as usual scenario shows a major collapse around the year 2060, which is in accordance to the Limits to Growth results from 1972 and the follow-up-publications from the Club of Rome.

Furthermore, the book demonstrates calculations of ecological footprints and sustainability by assessing our consumption and loss of work energy due to our use of resources and destruction of nature. These calculations lead to the following conclusions:

  • Maintain natural areas and the ecosystem services they provide.
  • Improve agricultural production by increasing efficiencies and technologies.
  • Shift our thoughts and actions from quantitative growth to qualitative development, for instance by using the three R’s.
  • Shift to renewable energy.
  • Leave today’s policy focused entirely on short-sighted economic considerations and start to discuss how we can improve environmental management, increase the level of education and research, and achieve greater equality in society.
  • Develop and promote alternative measures of welfare and well-being.
  • Reduce, rather than reward, financial speculations, exorbitant profits, and stock market gambling.

A new vision of Trans-Eurasian transportation

By Katherine Leitzell, IIASA Science Writer and Press Officer

The Trans-Siberian Railway is the longest railway in the world, connecting Moscow with Vladivostok and the Sea of Japan. Built at the turn of the 19th century, the railroad network connected remote Eastern Russia with the rest of the country, and created the first overland link between Europe and Asia.

In a meeting last week at IIASA, Russian researcher Yury Gromyko presented an equally ambitious transportation “megaproject” for the next century: the Trans-Eurasian Belt of Razvitie (Development in Russian), or the TEBR. The project, led by a group of leading Russian intellectual centers, would provide a new transportation network between markets in Europe and Asia, including high-speed rail, roads, as well as infrastructure such as pipelines and telecommunications networks.

Yet in Gromyko’s view the TEBR is also a development project that would bring new opportunities for trade and employment to the entire corridor of the construction. Gromyko described the project as a “New Future Zone,” which could revolutionize trade and economic development across Eurasia.

If the TEBR succeeds, Gromyko envisions new networks of smart cities in eastern Russia based on innovative technologies and new industries that would stem the tide of migration towards Moscow, instead pulling a new generation eastwards. “We need millions of young people to move to the Russian Far East. To attract them, there would need to be exciting jobs and affordable housing,” said Gromyko.

Gromyko presented the project at a workshop entitled, Development of Transport and Infrastructure in Eurasia. The meeting brought together transportation experts from across Eurasia to discuss visions for future development of the continent, and the key role of a multi-infrastructure approach in that development. Multi-infrastructure presupposes integration of different infrastructures from transportation to energy and telecommunications.

“Transportation and infrastructure are simply integral to economic development,” explains Michael Emerson, a senior researcher in the project who splits his time between the Centre for European Policy Studies (CEPS) and IIASA. “You cannot have one without the other.”

The event was the 5th in a series of scoping workshops arranged as part of the IIASA-coordinated project, Challenges and Opportunities of Economic Integration within a wider European and Eurasian Space, following previous workshops focused on research methodology, trade policy, non-tariff barriers, and energy. In addition to transportation and infrastructure projects, participants discussed investment and finance options for such major international efforts, as well as the challenges and opportunities of drawing private investment for long-term investments in infrastructure.

Several more scoping workshops are planned on different dimensions related to economic regional integration, explained project leader Elena Rovenskaya, the director of IIASA’s Advanced Systems Analysis Program. They create the foundation for the research phase involving researchers, business leaders, and policymakers from across Eurasia.

Network science and marketing: A virus’ tale

By Matthias Wildemeersch,  IIASA Advanced Systems Analysis and Ecosystems Services and Management Programs

FotoQuest Austria is a citizen science campaign initiated by the IIASA Ecosystems Services & Management Program that aims to involve the general public in mapping land use in Austria. Understanding the evolution of urban sprawl is important to estimate the risk of flooding, while the preservation of wetlands has important implications for climate change.

But how can we engage people in environmental monitoring, in particular when they are growing increasingly resistant to traditional forms of advertising? Viral marketing makes use of social networks to spread messages, and takes advantage of the trust that we have in the recommendation coming from a friend rather than from a stranger or a company.

Network science and the formal description of spreading phenomena can shed light on the propagation of messages through communities and can be applied to inform and design viral marketing campaigns.

Network science is a multi-disciplinary field of research that draws on graph theory, statistical mechanics, inference, and other theories to study the behavior of agents in various networks. The spreading phenomena in viral marketing show similarities with well-studied spreading processes over biological, social, physical, and financial networks. For instance, we can think about epidemics,which are well understood and allow for the design of optimal strategies to contain viruses. Another example is opinion dynamics, which received renewed research attention over the last years in the context of social media.  In contrast to diseases or computer viruses, which we aim to contain and stop, the goal of viral marketing is to spread widely, reaching the largest possible fraction of a community.

What makes viral marketing unique?
But some aspects of viral marketing are very different from what we see in other spreading phenomena. First of all, there are many platforms that can be used to spread information at the same time, and the interaction between these platforms is not always transparent. Human psychology is a crucial factor in social networks, as repeated interaction and saturation can decrease the willingness to further spread viral content. Marketing campaigns have a limited budget, and therefore it is meaningful to understand how we can use incentives and how efficient they are. This also means that it is essential to find the group of most influential people that can be used as seeds for the viral campaign.

Network science has addressed to a great extent all these individual questions, mostly under the assumption of full knowledge of the connections between the agents and their influence. Currently, so-called multiplexes are an active research field that studies the behavior of multi-layer networks. This research unveils the relationships between the dynamics of viral marketing, the connection pattern, and strength between the network layers. Although viral spreading may be unachievable in a single layer, for example a social network like Facebook, the critical threshold may be exceeded by joining different platforms. Within a given platform, people alike can be clustered using community detection algorithms. Once the communities are identified, influence maximization algorithms have been established to select these persons that maximize the spread of viral content. Although this discrete optimization problem is computationally difficult—or NP-hard—mathematicians have proposed algorithms that can efficiently predict who to target to give a campaign the best chance of going viral. On top of that, optimal pricing strategies have been developed to reward recommenders.

Although the literature is extensive, the nature of the results is often theoretical and involves mathematically complex models and algorithms. Considering that only partial information on the network is usually available, it is not straightforward to bring this knowledge back to a practical marketing campaign. So researchers in this field are trying to bridge the gap between theoretical results and practical problems. The generic, powerful methods of network science are sufficiently versatile to capture the specifics of real-world applications. As such, network science can provide guidelines that can bring great value for the design of heuristic methods in marketing strategies.

What do our models really represent?

By Dan Jessie, IIASA Research Scholar, Advanced Systems Analysis Program

As policymakers turn to the scientific community to inform their decisions on topics such as climate change, public health, and energy policy, scientists and mathematicians face the challenge of providing reliable information regarding trade-offs and outcomes for various courses of action. To generate this information, scientists use a variety of complex models and methods. However, how can we know whether the output of these models is valid?

This question was the focus of a recent conference I attended, arranged by IIASA Council Chair Donald G. Saari and the Institute for Mathematical Behavioral Sciences at the University of California, Irvine. The conference featured a number of talks by leading mathematicians and scientists who research complex systems, including Carl Simon, the founding Director of the University of Michigan’s Center for the Study of Complex Systems, and Simon Levin, Director of the Center for BioComplexity at Princeton University. All talks focused on answering the question, “Validation. What is it?”

To get a feel for how difficult this topic is, consider that during the lunch discussions,  each speaker professed to know less than everybody else! In spite of this self-claimed ignorance, each talk presented challenging new ideas regarding both specifics of how validation can be carried out for a given model, as well as formulations of general guidelines for what is necessary for validation.

For example, one talk discussed the necessity of understanding the connecting information between the pieces of a system. While it may seem obvious that, to understand a system built from many different components, one needs to understand both the pieces and how the pieces fit together, this talk contained a surprising twist: oftentimes, the methodology we use to model a problem unknowingly ignores this connecting information. By using examples from a variety of fields, such as social choice, nanotechnology, and astrophysics, the speaker showed how many current research problems can be understood in this light. This talk presented a big challenge to the research community to develop the appropriate tools for building valid models of complex systems.

Overall, the atmosphere of the conference was one of debate, and it seemed that no two speakers agreed completely on what validation required, or even meant. Some recurring questions in the arguments were how closely does a model need to mirror reality, and how do we assess predictions given that every model fails in some predictions? What role do funding agencies and peer review play in validation? The arguments generated by the talks weren’t limited to the conference schedule, either, and carried into the dinners and beyond.

I left the conference with a sense of excitement at seeing so many new ideas that challenge the current methods and models. This is still a new and growing topic, but one where advances will have wide-ranging impacts in terms of how we approach and answer scientific questions.

How can research help achieve resilience?

By Elisabeth Suwandschieff, Research Scholar, IIASA Ecosystems Services and Management Program

Vienna, Austria

We live in a world that is fluid and diverse. Yet policymakers have to find solutions to problems that are definitive and effective, able to adapt to uncertain, changing, and challenging environments. How can research help policymakers to achieve such resilience?

At last week’s 4th Viennese Talks on Resilience and Networks, I listened to a number of talks on this topic from prominent figures in politics, military, research, and the private sector who came together to discuss future potential pathways for Austria. Speakers from politics emphasized the importance of social solutions such as greater investment in education. Meanwhile researchers from IIASA and other institutions brought perspective from systems analysis methods and explained how research on dynamic systems can inform policy making.

System dynamics view
From the research perspective, IIASA’s Brian Fath and others brought a systems analytical view of complex systems and their dynamics. They explained that complex systems such as organizations, businesses, and cities go through different stages in their “ecocycle.” Understanding the cycle and process is key to influencing its development.

FAS.research Director Harald Katzmair argued that life, as a complex system, can be seen as a process of growth, stagnation, destructurization and reorganization. In a recent research project, Katzmair found that the main factor in achieving resilience was the ability of the system to remain flexible through improvisation, collaboration, behavioral change and openness. If we apply this to our understanding of the world it becomes necessary to rethink our approach to leadership in every aspect.

“Our world is not a closed system; it does not consist of one choice, one idea, one currency,” said Katzmair.

Fath said that resilience is achieved by successfully managing each stage of the life cycle, explaining that even collapse can be seen as a key feature of system dynamics, because it results in developmental opportunities. Through disturbance and adaptive change in the landscape, new landscapes can be shaped.

Applying research to resilience
Many of the research talks were mathematical and complex. How can such research help in achieving resilience on a practical level? The issue for policymakers is that they have to provide definitive solutions when actually we live in a world that is fluid and diverse – therefore we need a diversified portfolio of problem solving. That is, solutions must be broad without losing focus. They must be effective, but remain flexible and open.

Research can bring different experiences together, provide a platform and a common language that can be shared. Systems thinking is a powerful way to condense the different ways of thinking and produce a portfolio of options rather than provide rigid solutions.

Climate change missing from government risk agendas

By Leena Ilmola-Sheppard, IIASA Advanced Systems Analysis Program

When government officials speak about risks, they are usually referring to natural disasters. And it seems in these discussions that the increasing frequency of flooding, droughts, snow storms, and hurricanes have no link to climate change nor mitigation of it.

Last week,  I had an opportunity to sit and listen to discussions at the fourth annual Organisation for Economic Co-operation and Development (OECD) High Level Risk Forum.  The objective of the forum is to initiate joint development of the national level risk management tools and procedures.  National risk directors form their Prime Minister’s Offices and OECD ambassadors spent three rainy days from December 10-12 discussing risk.

The most of the time, the discussion centered around disaster risks.  Whatever the theme of the  session, the discussion ended up on disaster management, disaster costs, or best practices. This is a theme that was recognized to be of importance in every government.  The other risks that were presented were terrorism, the Ebola epidemic, and illicit trade. The missing themes–that I had expected to be on the agenda–were technology related, financial risks and political risks.

Margaret Wahlstrom, Special Representative of the UN Secretary General for Disaster Risk Reduction, gave the best presentation. Her key message war that climate change related issues were not integrated well enough with risk management.  Kate White from the US Army Corps of Engineers supported Wahlstrom by stating that the climate change will radically change disaster management goals, procedures, and volume of investment.  There should be a strong motivation for that, she said, as disasters are coming more expensive.  According to her data, the total cost of hurricane Sandy was 65 billion US$.

The Australian government calculations presented in the meeting are very revealing as well; from Australian government is spending around 400 million AU$ for disaster prevention and response, and 2.6 billion AU$  for recovery.  As the Australian example shows, governments have a long way to go from words to action. Governments have not yet realized the role of mitigation, at least not in the budgeting level.

The main theme of this year’s forum was “risk and resilience.”  So the word was used a lot in all of the presentations.  However, the concept of resilience seems to have many meanings and concrete substance behind the word is ambiguous.  Margaret Wahlstrom pointed out that there is a need for a cross-discipline understanding of resilience, as well as for a generic resilience measurement system.   Concrete quantitative indicators would help policymakers to assess the development actions needed, improvement achieved, and provide justification for development actions.

The most vivid discussion concerned the relationship of the national risk management and public involvement. Countries such as the United Kingdom promote full transparency and active risk communications, while some of the governments such as Singapore focus on communicating the vision and improvement ideas instead of risks.  My interpretation of the discussion is that many of the represented government experts perceive risks to be too complicated to communicate to a general audience.  The Nordic countries even go beyond communication, to encourage and support self-organized actions. For example the government supported people when they started to offer shelter and places to sleep for those that got stuck on the road during the October storms of this year, the worst to hit the region in decades.
