Monday is World Water Day, but I suspect relatively few will have noticed.
While the world is rightly moving to address the challenges presented by climate change and depleting supplies of fossil fuels, the same awareness and consensus does not exist when it comes to addressing our usage of water. Yet the harsh fact is that we will probably run out of water long before we run out of fuel. Continue reading
“Tomorrow’s Cities”, a succinct and inspiring film (15 minutes long), presents a compelling and easy to understand account of the major developmental challenges facing our cities in South Africa and more broadly cities of the global south. Framed within these challenges, the film unfolds a vision, through the voice of a school child and exciting use of animation, and proposes practical solutions towards achieving breathable, sustainable, equitable and low carbon urban futures.
The film is intended as a learning tool to raise discussion and awareness and ultimately inspire action toward the development of sustainable and equitable, low carbon cities.
The internet has created many new opportunities for people to get richer around the world. But are the benefits of access to the net filtering down to the very poorest in society? A shanty town in Brazil is a good place to find out.
Babilonia is a favela, a slum district, of about 80,000 inhabitants, most of them very poor. It’s located in Brazil’s second city Rio de Janeiro, close to the world famous Copacabana beach. Continue reading
‘Energy transition towards economic and environmental sustainability: Feasible paths and policy implications’
This paper focuses on growth feasibility in an era of increasing scarcity of fossil fuels. A stylised dynamic model illustrates the implications of investing in smooth technological progress in the field of renewable energy. Positive rates of GDP growth sustained by fossil fuels entail, on the one hand, more income available for R&D in renewable energy sources, and on the other, an acceleration of the exhaustible resource depletion time. Our model explores such a trade-off and highlights the danger of high growth rates. Policies should target low growth rates, stimulate investment in alternative energy sources and discourage consumption growth. (abstract) Continue reading

The concepts of welfare, economic growth, production, environmentally sustainable national income, environmental sustainability, environmental function and asymmetric entering are defined, because the confusion about these concepts hampers sound information. Based on these concepts the arguments are enumerated why it is plausible that environmental sustainability most probably cannot be attained with a growing production level (national income, NI) and why broad acceptance of a lower production level, meaning de-growth of production, will make attaining this goal much easier or at least possible. Some consequences of unsustainable development are provided and the alleged conflict between employment and environment is refuted. The conclusion is that our planet is threatened by a wrong belief in a wrongly formulated growth. (abstract) Continue reading
The UN called in the world’s top scientists today to review a report by its climate body, four months after public confidence in the science of global warming was shaken by the discovery of a mistake about the melting rates of Himalayan glaciers.
In an announcement at the UN in New York Ban Ki-moon, the UN secretary general, and Rajendra Pachauri, the much-criticised head of the Intergovernmental Panel on Climate Change, said the InterAcademy Council, which represents 15 national academies of science, would conduct the independent review.
