Time Running Out for Sustainable Future

 
Worldwatch maps sustainable 'good life', warns great changes must be made before it's too late


The planet will not be able to sustain levels of consumption typical of today's 'consumer class' without irreparable consequences to the globe, according to the just released Worldwatch Institute in State of the World 2012: Moving Toward Sustainable Prosperity. They have proposed a redefinition of 'the good life' as one that aligns with sustainable practices and have mapped out a hopeful plan leading up to this year's Rio+20; however, the plan's window of opportunity is quickly closing.

"The aspirations of the original 1992 meeting in Rio collided with a set of painfully sobering developments, including unfriendly politics, orthodox economics, and a dominant culture of consumerism. The 20 years since then have made it clear that necessary change is not merely technical, but encompasses changes in lifestyle, culture, and politics," states Worldwatch.

"There won't be much point in revisiting the Rio+20 conference in another 20 years to try to figure out what went wrong," says Worldwatch President Robert Engelman. "We know enough right now about the state of the world to see clearly that we have to change the way we live and the way we do business. Working out new paths towards true sustainability will take much more than a conference of governments, though such a gathering can help. The task begins with the recognition that perpetual economic and demographic growth aren't possible on a finite planet. We can work with the hope that ecological stability is possible, along with a good life based on health, literacy, strong communities, and access to 'enough' rather than ever more."

Time Running Out to Ensure Sustainable Prosperity for All (Worldwatch Institute):
"The Industrial Revolution gave birth to an economic growth model rooted in structures, behaviors, and activities that are patently unsustainable," says Worldwatch Senior Researcher Michael Renner, co-director of State of the World 2012. "Mounting ecosystem stress and resource pressures are accompanied by increased economic volatility, growing inequality, and social vulnerability. It is difficult to avoid the conclusion that the economy no longer works for either people or the planet."
Instead, we need to reprioritize basic needs and pursue true sustainable prosperity: development that allows all human beings to live with their fundamental needs met, with their dignity acknowledged, and with abundant opportunity to pursue lives of satisfaction and happiness, all without risk of denying others in the present and the future the ability to do the same. This, in turn, means not just preventing further degradation of Earth's systems, but actively restoring them to full health. [...]
The report's 35 contributors describe many of the currently untenable social and economic patterns and explore opportunities for creative alternatives on sustainability topics ranging from agriculture, communication technologies, and biodiversity to "green" construction, local politics, and global governance. Specific topics include:
  • A Green Economy that Works for Everyone: For industrial, emerging, and developing countries, a green economy will mean different things. But they have in common the need to create green jobs that offer a decent living, and they all can benefit from policy innovations such as a network of cooperative green innovation centers, a standard-setting global "top runner" program, green financing and skills training, and greater economic democracy. 
  • Degrowth in Overdeveloped Countries: Humanity uses 1.5 Earths' worth of ecological capacity, with much of that consumed by overdeveloped industrial countries. Sustainable prosperity will require economic degrowth in these countries. This can be achieved by a mix of tax shifting, shortening work weeks, denormalizing certain types of consumption, and de-marketizing certain sectors of the economy, such as food production and child care. 
  • Inclusive and Sustainable Urban Development: Urban poverty is pervasive, and absolute numbers are expanding in both the developed and developing worlds: some 828 million people live in slums worldwide. Urban planning needs to include strategies such as explicit and transparent spatial plans, democratic engagement of the poor and community-based organizations, and coordination across sectors, especially affordable housing, transportation, and economic development. 
  • Sustainable Transportation: Today there are nearly 800 million cars on the world's roads, and in the developing world transportation is the source of up to 80 percent of harmful air pollutants. A sustainable and socially progressive alternative requires a shift toward denser cities that generally require less motorized travel, invest in high-quality transit, and support vibrant, healthy communities by enabling walking and cycling. 
  • Information and Communications Technologies (ICTs): More than half of the world's population lives in cities, and 90 percent of urbanization is occurring in the developing world. ICTs can help cities become safer, cleaner, and more sustainable places to live, but they are currently underutilized in both the developed and developing worlds. Reversing this trend must go beyond the current public-private partnerships and "smart cities" projects by providing broad public access to data and boosting public involvement. 
  • Measuring Sustainable Urban Development: Since the 1992 Earth Summit in Rio, there has been limited progress in developing a universal sustainability indicator system that is scientifically valid and credible. This has been true in the United States as well, but efforts are under way to develop a database of indicators that will inform discussions at Rio+20 about how to measure urban sustainability. 
  • Reinventing the Corporation: Transnational corporations (TNCs) have evolved over the past five centuries into globally influential entities. They often go unchecked, with no limits placed on their impacts on society, the environment, or the economy. TNCs must adapt if sustainability is to become a reality, including shifts in their purpose, ownership, capital investment, and governance. 
  • The Global Architecture of Sustainable Governance: Sustainability efforts worldwide will be shaped by the reforms being discussed for the United Nations Environment Programme (UNEP). If UNEP is going to play a valuable and productive role in these efforts, it must enjoy increased authority and financial resources, but above all it must be better connected to other international agencies so it can play the coordinating and visionary role its founders had in mind. 
  • Population Growth Strategies: In 2011, global population passed the 7 billion mark, and confronting population growth is critical to the future sustainability of the planet. Over time, population growth will end and reverse with no need for "population control" through assuring reproductive health and rights for all, adequate education for girls and boys, and equal economic activity for both sexes with internalization of the environmental costs of economic activity. 
  • Sustainable Buildings: The construction and operation of buildings use 25-40 percent of all produced energy, accounting for a comparable share of global carbon dioxide emissions. We must aim for the goals of net zero energy use, zero emissions, and zero waste if new construction and existing buildings are going to be sustainable. 
  • Public Policy and Sustainable Consumption: Combating the rise of consumerism will require government involvement, including advertisement management, tax modification to include the true cost of a product or service, and the establishment of sustainability certification programs. 
  • Mobilizing the Business Community: Our current economic model does not consider planetary limits, is socially exclusive, and places private interests above public ones. A recipe for a successful 21st-century economy needs to be green, inclusive, and responsible, which will take a combination of business-led voluntary initiatives reinforced by new corporate structures and strong government policy and public oversight. 
  • Sustainable Agriculture: Almost 2 billion people are fed by produce from the 500 million small farms in developing countries. Yet these small-scale producers are some of the most food-insecure people: 80 percent of the world's hungry live in rural areas. To optimize the productivity and environmental sustainability of small farms, future agricultural policy must combine a rights-based approach with legislation that is localized and culturally specific. 
  • Food Security and Equity: In recent decades, factory farming has increased meat, egg, and dairy consumption worldwide, particularly in the developing world. But this industrial meat production system has been harmful to human health and the environment. The internalization of costs, restoration of ecosystems, and education of the public----among other strategies----can help create a new food system that is more efficient, equitable, and climate-compatible. 
  • Biodiversity: The rate at which species are becoming extinct is estimated to be up to 1,000 times higher today than in pre-industrial times. Efforts such as the Intergovernmental Platform on Biodiversity and Ecosystem Services are needed to better understand and reverse the erosion of nature's resiliency. 
  • Valuation of Ecosystem Services: The human ecological footprint has grown so large that progress is now constrained more by limits on natural resources and ecosystem services than by limits on infrastructure or technology. Ecosystem services help evaluate the benefits derived from ecosystems by assigning a monetary or physical unit to those benefits, which can in turn help to better facilitate natural resource management. 
  • Local Governance: Decisions at the local level can be the greatest catalysts for progress because they contribute directly to poverty reduction, job growth, gender equity, and environmental protection. As a result, the development of local democratic procedures that are transparent and reliable is critical to global sustainable development.

Notre Dame researchers develop paint-on solar cells

Imagine if the next coat of paint you put on the outside of your home generates electricity from light—electricity that can be used to power the appliances and equipment on the inside.

A team of researchers at the University of Notre Dame have made a major advance toward this vision by creating an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy.

"We want to do something transformative, to move beyond current silicon-based solar technology," says Prashant Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an investigator in Notre Dame's Center for Nano Science and Technology (NDnano), who leads the research.

"By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we've made a one-coat solar paint that can be applied to any conductive surface without special equipment."

The team's search for the new material, described in the journal ACS Nano, centered on nano-sized particles of titanium dioxide, which were coated with either cadmium sulfide or cadmium selenide. The particles were then suspended in a water-alcohol mixture to create a paste.

When the paste was brushed onto a transparent conducting material and exposed to light, it created electricity.

"The best light-to-energy conversion efficiency we've reached so far is 1 percent, which is well behind the usual 10 to 15 percent efficiency of commercial silicon solar cells," explains Kamat.

"But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future."

"That's why we've christened the new paint, Sun-Believable," he adds.

Kamat and his team also plan to study ways to improve the stability of the new material.

NDnano is one of the leading nanotechnology centers in the world. Its mission is to study and manipulate the properties of materials and devices, as well as their interfaces with living systems, at the nano-scale.

Corporate Monopolies 'May Dominate Green Economy'




NEW DEHLI - The global push towards a 'green economy' risks being hijacked by large corporate monopolies trying to gain control over natural resources, a report has warned.

A report released earlier this month has warned that global companies, positioning themselves for a post-petrochemical future, may use the idea as a pretext for gaining control over biomass resources, which would eventually replace petroleum as the feedstock for energy and for industrial products. There is a growing emphasis on the concept of a green economy in the run-up to the UN Conference on Sustainable Development (Rio+20), in June 2012, in Brazil. A green economy is widely seen as a way of tackling environmental challenges including climate change, failing fisheries and water security.

But a report released earlier this month (14 December) has warned that global companies, positioning themselves for a post-petrochemical future, may use the idea as a pretext for gaining control over biomass resources, which would eventually replace petroleum as the feedstock for energy and for industrial products.

The report, published by an international nongovernmental organisation Action Group on Erosion, Technology and Conservation (ETC Group), in Canada, says that most of this biomass is in developing countries, where it is managed by poor peasants, forest dwellers, fishing communities and livestock-owners whose livelihoods depend on them.

The report urges developing countries to craft policies that will protect them from such encroachments.

If they do not, they risk being "seduced" by the promise of quick green techno-fixes, which appear as "a politically expedient" alternative plan to save the climate, the report says, because "techno fixes are not capable of addressing systemic problems of poverty, hunger and environmental crises".

"In the absence of effective and socially responsive governance and government oversight, the bio-based economy will result in further environmental degradation, unprecedented loss of biodiversity and the loss of remaining commons," it says.

The report's authors said they were not rejecting the concept of green economy, but that countries should build sustainable economies based on using new, more socially and ecologically sustainable economic models.

Hoysala Chanakya, principal research scientist, at the centre for sustainable technologies at the Indian Institute of Science, said that the report was right to highlight that there was potential for corporate take-overs in the absence of adequate policy support and that developing countries need to have policies to ensure that public resources do not get monopolised.

He added that the assumption that technological advances in algal or plant-based biofuel systems, for example, would solve environmental problems, is based partly on hype.

"The [biomass-based] technologies are still in a stage of infancy," Chanakya said. They also leave lots of organic waste which can be polluting, he added.

Other sustainable development policy experts in India suggested that a solution to some of the problems forecast by ETC Group was to decentralise food and energy security programmes and push for small, farmer-centred agriculture.

Instead of the "overarching generalised programmes involving blanket application of solar or hydrogen power" developing countries should move towards decentralised, locally-managed food and energy security programmes that are rooted in their unique local environments, said Rajeswari Raina, scientist at National Institute of Science, Technology and Development Studies.

Ambuj Sagar, professor of policy studies at the Indian Institute of Technology, agreed: "We need a different narrative that places value on the livelihoods of small farmers in developing countries rather than on food production at lowest cost and protecting interests of farmers in industrialised countries through subsidies."

"Private-sector and market-oriented food and agriculture systems are unlikely to deliver this kind of outcome since that is not the primary objective of these actors and institutions."
