"Sustainable Smart Towns is a three stage program that Heyfield is showcasing as the first town to become sustainable as a whole community targeting 25% plus of its population."

"On 9 May 2013 The National Sustainability Council presented Sustainable Australia Report 2013 to Minister Burke. The report provides a picture of Australia - what we look like and who we are. It tells the story of how we have changed as a nation over the last 30 years. We have made great progress in many areas. Australians are living longer, our health and levels of educational attainment have improved. We have benefited from a strong economy, with low unemployment and increasing incomes. However, inequality has increased and the health of our natural environment has continued to decline in some key areas. The report provides an evidence base for decision-making and planning about the future. It highlights a number of trends in Australia and the world that are set to have a significant impact on the next generation of Australians. We need to plan for an ageing population, rising health costs, growing cities and changes in traditional work and family roles. The National Sustainability Council intends to use the report, the first of its kind in Australia, as a starting point for a national conversation about our future."

Australia has one of the highest incidences of pet ownership in the world with latest data showing that 63% of the 7.5 million households own a pet. As the dog population in Australia continues to grow, so will the issue of dog 'waste' disposal in a waste management system of increasing urbanisation, a limited amount of suitable park spaces and shrinking landfill sites. On average, a dog produces 0.34 kilograms (kg) of feces per day. Consequently, there is approximately 1,400 tonnes (t) of dog waste to be disposed of every day in Australia; 490,000 tonnes (t) per year. Therefore we want to build an anaerobic methane digester to process the dog waste (and other appropriate wastes) to create a biogas that can serve as renewable energy source to super-power your dog parks. 

"Several studies have shown that global crop production needs to double by 2050 to meet the projected demands from rising population, diet shifts, and increasing biofuels consumption. Boosting crop yields to meet these rising demands, rather than clearing more land for agriculture has been highlighted as a preferred solution to meet this goal."

Finding creative solutions to energy issues has become a major priority for Google co-founder and CEO Larry Page in recent years. For the obvious reasons -- a growing population, increasingly scarce resources, and climate change -- he believes that the corporate world needs to operate more sustainably, and he is determined to build the nation's first zero-carbon company. This means a business that ultimately is so energy efficient and uses so much clean power that it emits no greenhouse gas -- a very tall order indeed. Experts aren't sure whether it's even possible for a company to emit no carbon, but Google is trying to come as close to that goal as possible. "As we became a bigger user of energy, we wanted to make sure we were not just part of the problem, but part of the solution," says Urs Hölzle, Google's employee No. 8 and a senior vice president who oversees the company's green initiatives.

"The United States has seen quite the bike boom over the last decade or so, and it doesn't look to be slowing down anytime soon. According to the Christian Science Monitor, bike commuting grew by 47% nationwide between 2000 and 2011. Unsurprisingly, it was Portland, Oregon that took the lead with 250% growth, followed by Washington, D.C., San Francisco, Boston, Seattle, and New York City. Still, only 1% of Americans are biking on the regular, compared to 26% of people in the Netherlands, 10% of Germans, and 19% of the Danish population. The growth in the United States is of course still positive, and a great indication that there will be widespread public support as more cities begin to integrate cycling into the transportation grid."

"Half of Australia's states and territories have now banned single-use, lightweight plastic bags, the latest being Tasmania. And while they are Australia's least-populated states and territories, pressure is growing on the governments of New South Wales, Victoria, Queensland and Western Australia to do the same."

"Since the Waubra wind farm started generating power in 2009, the town has acquired a dubious reputation: the so-called `Waubra Disease' is now known internationally. But how much sense does it make? Whilst there's a small number of complainants among the population of 500, there are also 30 families hosting turbines on their land as well as many turbine neighbours -- including community leaders - who live happily with the turbines. Neil Barrett has been researching the Waubra situation for the past year. Whilst his attempts so far to understand the issues raised by complainants have been unsuccessful, it has become clear to him that the apparent good health and well-being of the turbine hosts and most of their neighbours deserves to be more widely known.

"United Nations Secretary-General Ban Ki-moon has said that the battle for global sustainability will be won or lost in the world's cities. Cities and urban areas are estimated to account for 80 per cent of global greenhouse gas emissions, and more than half of the world's population live in them, so what we do in our urban centres will, to a large extent, define the future of our world. Governments are struggling to agree on action against climate change, but thankfully many city authorities are just getting on with tackling the problem as best they can. Element takes a look at what authorities in Auckland, Wellington and Christchurch are expecting, how they are trying to minimise the damage and preparing for the worst, and how their plans shape up against those elsewhere."

"By the end of this century, Earth may be home to 11 billion people, the United Nations has estimated, earlier than previously expected. As part of a week-long series, LiveScience is exploring what reaching this population milestone might mean for our planet, from our ability to feed that many people to our impact on the other species that call Earth home to our efforts to land on other planets. Check back here each day for the next installment."

"Bill Gates sees meat alternatives a a big part of the future of food. On his blog, The Gates Notes, there is a feature called The Future of Food, where he explains how food scientists are starting to reinvent meat, and how this could help the whole world. Gate explains that worldwide meat consumption has doubled over the past two decades and is expected to double again by 2050 when, as we know, world population is expected to reach at least 9 billion. It is just over 7 billion now."

"With huge tracts of land, sunshine and plentiful water across the northern states and territories, there are high hopes for Australia's post-mining future pinned on its ability to produce enough agricultural product to feed Asia's rapidly growing population. Agriculture Minister Barnaby Joyce wants to temper those expectations."
