20 July 2017, The Conversation, Farming the suburbs – why can’t we grow food wherever we want? Food provides the foundations for human flourishing and the fabric of sustainability. It lies at the heart of conflict and diversity, yet presents opportunities for cultural acceptance and respect. It can define neighbourhoods, shape communities, and make places. In parts of our cities, residents have embraced suburban agriculture as a way to improve access to healthier and more sustainably produced food. Farming our street edges and verges, vacant land, parks, rooftops and backyards is a great way to encourage an appreciation of locally grown food and increase consumption of fresh produce. Despite these benefits, regulations, as well as some cultural opposition, continue to constrain suburban agriculture. We can’t grow and market food wherever we like, even if it is the sustainable production of relatively healthy options. While good planning will be key to a healthier, more sustainable food system, planning’s role in allocating land for different uses across the city also constrains suburban agriculture. Two steps towards healthier food systems: Making our food systems healthier and more sustainable requires a two-step approach. First, we need to fortify the parts of the system that enable access to healthy food options. Second, we need to disempower elements that continuously expose us to unhealthy foods. Although food is a basic human need, the way we consume food in many countries, including Australia, is harmful to the environment and ourselves. Many of us don’t eat enough fresh and unprocessed foods. The foods we do eat are often produced and supplied in carbon-intensive and wasteful ways. Primarily through land-use zoning, town planners can help to shape sustainable and healthy food systems. Read More here

12 July 2017, The Guardian, Commentators who don’t understand the grid should butt out of the battery debate. Criticising South Australia’s battery for not meeting peak demand is akin to raging at your smartphone because it can’t send a fax. he Australian electricity grid’s most recently announced extremity is a gargantuan battery system in South Australia, designed to bolster grid security. The facility has been met mostly with a warm welcome, interspersed with weird, interesting and tense hostility. Buried in the mix of reactions are clues about how a new phase of grid transition might play out, as we switch from the rapid build out of zero carbon power sources to building and integrating them into a system designed for fossil fuels.Before we interrogate the misunderstandings of South Australia’s new battery, we have to step back and look at the system as a single, electric organism.

11 July 2017, The Conversation, Why a population of, say, 15 million makes sense for Australia. Population growth has profound impacts on Australian life, and sorting myths from facts can be difficult. This article is part of our series, Is Australia Full?, which aims to help inform a wide-ranging and often emotive debate. Neither of Australia’s two main political parties believes population is an issue worth discussion, and neither currently has a policy about it. The Greens think population is an issue, but can’t come at actually suggesting a target. Even those who acknowledge that numbers are relevant are often quick to say that it’s our consumption patterns, and not our population size, that really matter when we talk about environmental impact. But common sense, not to mention the laws of physics, says that size and scale matter, especially on a finite planet. In the meantime the nation has a bipartisan default population policy, which is one of rapid growth. This is in response to the demands of what is effectively a coalition of major corporate players and lobby groups. Solid neoliberals all, they see all growth as good, especially for their bottom line. They include the banks and financial sector, real estate developers, the housing industry, major retailers, the media and other major players for whom an endless increase in customers is possible and profitable. However, Australians stubbornly continue to have small families. The endless growth coalition responds by demanding the government import hundreds of thousands of new consumers annually, otherwise known as the migration intake. The growth coalition has no real interest in the cumulative social or environmental downside effects of this growth, nor the actual welfare of the immigrants. They fully expect to capture the profit of this growth program, while the disadvantages, such as traffic congestion, rising house prices and government revenue diverted for infrastructure catch-up, are all socialised – that is, the taxpayer pays. The leaders of this well-heeled group are well insulated personally from the downsides of growth that the rest of us deal with daily. A better measure of wellbeing than GDP The idea that population growth is essential to boost GDP, and that this is good for everyone, is ubiquitous and goes largely unchallenged. For example, according to Treasury’s 2010 Intergenerational Report: Economic growth will be supported by sound policies that support productivity, participation and population — the ‘3Ps’. If one defines “economic growth” in the first place by saying that’s what happens when you have more and more people consuming, then obviously more and more people produce growth. The fact that GDP, our main measure of growth, might be an utterly inadequate and inappropriate yardstick for our times remains a kooky idea to most economists, both in business and government.

29 June 2017, Renew Economy, Coal on limited lifespan as CCS hopes go up in smoke. The coal industry is facing a new crisis point as a group of leading scientists call for the construction of new coal generators to cease within three years, and as the industry’s flagship “clean coal” and carbon capture and storage project went up in smoke in the US. As reported elsewhere on this web site, the US energy utility Southern Co finally gave up on its much-vaunted Kemper coal gasification and CCS project, after costs soared from $US1.8 billion to more than $US7.5 billion ($A10 billion), and it realised it wasn’t going to work. On Wednesday, US time, it announced it would cease operations immediately on the coal component of the project, and just use the asset as a gas generator. Shareholders already saddled with $US3.1 billion of losses face a further $US3.4 billion write down if Southern Co can’t convince regulators to pass those costs on to consumers bills. The spectacular failure of the Kemper facility – more than $US7.5 billion for a 582MW plant, the most expensive in US history per MW – comes amid a renewed call for new coal generation to be stopped in its tracks, and for existing coal generation to be wound back rapidly. In an article in Nature magazine, more than 60 scientists and prominent leaders, including the former UNFCCC secretary Christiana Figures, and former ACTU president Sharan Burrow, now general secretary of the International Trade Union Confederation, say the world has three years to set emissions on the right course. It recommends a six-point plan, including no new coal generators post 2020, accelerating wind and solar and other renewables, retiring all coal-fired generators and boosting electric vehicles. “The climate math is brutally clear: While the world can’t be healed within the next few years, it may be fatally wounded by negligence until 2020,” writes co-author Hans Joachim Schellnhuber from the Potsdam Institute for Climate Impact Research.
