Our industrial civilization faces the same threats of collapse that earlier versions such as the Mayans experienced, a study to be published in Ecological Economics has warned. The idea is far from new, but the authors have put new rigor to the study of how so many previous societies collapsed, and why ours could follow.

Lead author Mr Safa Motesharrei is no wild-eyed conspiracy theorist. Motesharrei is a graduate student in mathematics at the National Socio-Environmental Synthesis Center, a National Science Foundation-supported institution, and the research was done with funding from NASA’s Goddard Space Flight Center.

“The fall of the Roman Empire, and the equally (if not more) advanced Han, Mauryan, and Gupta Empires, as well as so many advanced Mesopotamian Empires, are all testimony to the fact that advanced, sophisticated, complex, and creative civilizations can be both fragile and impermanent,” the forthcoming paper states

Two key social features are identified that contributed to the collapse of every civilization studied: “The stretching of resources due to the strain placed on the ecological carrying capacity,” and “The economic stratification of society into Elites [rich] and Masses (or “Commoners”) [poor]”.

If these look familiar, so do the factors that make up the resource side of the equation, with climatic change, and scarcity of water and energy key among them, although for others climate variation was a matter of bad luck, rather than their own actions.

The model Motesharrei used, Human And Nature Dynamics (HANDY), explores the relationship between population and resources, drawing heavily on predator-prey models used by ecologists. Four key factors were included in the model: Elites, Commoners, nature and wealth. Equations of how these interact were created with varying inputs. The outcomes were not pretty. The timing and shape of collapses varied, but the societies that most closely resembled our own doomed themselves, through overuse of resources exacerbated by economic stratification.

In one scenario many commoners do make it into the elite population at year 750, but the “scarcity of workers” caused a collapse by year 1000. In another so many of the Earth’s resources are consumed that society, and the ecology of the planet, are doomed by the year 500.

“It is important to note that in both of these scenarios, the Elites — due to their wealth — do not suffer the detrimental effects of the environmental collapse until much later than the Commoners,” the paper notes.

If those year numbers seem comfortingly far off, be aware that the year zero in these models is well behind us. Nevertheless, contrary to much of the reporting, the model does not provide a useful timeline for when we can expect to see the world we live in turn into something that resembles a post-apocalyptic nightmare, although studies of the convergence of climate and resource challenges suggest we may witness drastic food crises within a little over a decade.

In every economic bubble people looking back to past crashes are told “this time it is different”. Certainly some things have changed for modern civilization compared to the others Motesharrei has looked at. Technological developments that provide access to greater resources is the most frequently mentioned difference. Motesharrei responds, “Technological change can raise the efficiency of resource use, but it also tends to raise both per capita resource consumption and the scale of resource extraction, so that, absent policy effects, the increases in consumption often compensate for the increased efficiency of resource use.”

One advantage we do have, however, is much greater knowledge of what has gone wrong in the past, and therefore the capacity to build models like HANDY. In a presentation of an earlier draft of this work in 2012 Motesharrei noted, “Simple models provide a great intuition and can teach us invaluable points. It is crucial to have a measure that can give us an early warning of collapse. Carrying Capacity tells us when overshoot happens, and this can be defined by noticing the decline in wealth.”

Some coverage of the announcement has described disaster as inevitable, but that is not the paper’s conclusion at all. “Collapse can be avoided and population can reach equilibrium if the per capita rate of depletion of nature is reduced to a sustainable level, and if resources are distributed in a reasonably equitable fashion,” it argues.

Although the study has reportedly passed peer review it is yet to be published. It received global attention after a pre-release version was provided to The Guardian.

Update: NASA has issued a clarification stressing that this study does not necessarily represent NASA’s viewpoint. Noting that they fund many studies they stress it “was not solicited, directed or reviewed by NASA”. The funding came about because the project was “utilizing research tools developed for a separate NASA activity.” The clarification points out, “As is the case with all independent research, the views and conclusions in the paper are those of the authors alone.”

Following the 2013 Future of Places conference in Stockholm, Sweden, Ax:son Johnson Foundation, together with its partners UN-Habitat and Project for Public Spaces, are pleased to announce the next conference in the series. The theme of the 2014 conference, “Streets as Public Spaces,” reflects the importance of modern street design in enabling – or damaging – the well-being of city dwellers.  Streets serve a broader function than the efficient conveyance of vehicles or pedestrians from one location to another.  They, and their adjacent spaces, form a critical connective network within the city, profoundly influencing, and potentially limiting, social and economic development.

BACKGROUND TO THE PUBLISHER:

Towards Habitat III 2016

‘Habitat III’ is the Third United Nations Conference on Housing and Sustainable Urban Development, to take place in 2016.

Habitat III will be one of the first global conferences after the Post 2015 Development Agenda. It is an opportunity to discuss and chart new pathways in response to the challenges of urbanization and the opportunities it offers for the implementation of the sustainable development goals.

The conference promises to be unique in bringing together diverse urban actors such as governments, local authorities, civil society, the private sector, academic institutions and all relevant interest groups to review urban and housing policies affecting the future of cities within an international governance architecture, with a view to generate a ‘New Urban Agenda’ for the 21st century which recognizes the ever-changing dynamics of human civilization.

Habitat III offers Member States an opportunity to discuss a New Urban Agenda that will focus on policies and strategies that can result in effectively harnessing the power and forces behind urbanization.

First ever global assessment of best practices in green growth reveals pathways for success – Regions 20

First ever global assessment of best practices in green growth reveals pathways for success

Category: News

Published on Tuesday, 11 March 2014

R20 is pleased to announce the release of the summary of key findings from the Green Growth Best Practice (GGBP) book, ahead of its full release in June 2014. This summary report was unveiled at the 1st Global Conference on Partnership for Action on Green Economy (PAGE) in Dubai earlier this month.

The Green Growth Best Practice book is the result of an initiative led by the Global Green Growth Institute (GGGI), and was written by 75 authors in the field of green growth from a variety of organizations, including R20.

Lead authors Christophe Nuttall (R20’s Executive Director) and Tadashi Matsumoto (OECD Senior Policy Analyst), wrote the chapter on National and Subnational Integration that explores approaches to advancing green growth through coordinated national and subnational programs and across government. Several co-authors contributed to this chapter, including Denise Welch (R20’s Director of Research & Technical Initiatives).

By analyzing around 60 specific government programs from different countries and regions around the world, the GGBP makes recommendations for effective green growth approaches, based on the experience of early movers, and provides practical guidance for national and subnational policy planning.

Green growth strategies play vital roles in unlocking synergies between economic growth, environmental protection and poverty reduction, and enabling a transition to an inclusive green economy.

The Synthesis of Key Findings elaborates on nine key actions that enable effective green growth policy:

·      Use well-designed planning and coordination processes;

·      Establish clear visions, targets, and baselines;

·      Undertake robust analysis and balanced communication of the benefits of green growth;

·      Prioritize options and develop credible pathways towards targets;

·      Design policies to address multiple goals and respond to specific market failures;

·      Design public finance instruments to overcome barriers and mobilize private investment;

·      Tap the power of public-private collaboration;

·      Pursue mutually reinforcing action across all levels of government;

·      Build and maintain strong monitoring and evaluation systems.

The report and supporting case studies will also be available in the form of an online “living handbook,” which will feature an interactive interface.
