Free energy does not occur in nature

by

It’s not just that what we generally think of as free energy doesn’t occur in nature, but also that free energy does occur in the everyday lived environments of people in industrial nations, which we might thus say are unnatural. So what are instances of free energy that we experience in our lives, and why do they matter?

Urban agriculture isn’t new

by

In fact, it’s been around since 3,500 BC when Mesopotamian farmers began setting aside plots in their growing cities. In a review of urban agriculture throughout modern history at a symposium at Dumbarton Oaks in Washington, D.C., a diverse set of academics and designers ranging from historians to landscape architects discussed how the practice has evolved over the ages, often been highly ideological, and continues to be loaded with meaning. Organized by professor Dorothee Imbert, ASLA, chair of the master’s of landscape architecture program at Washington University in St. Louis, the conference looked at why urban agriculture is such a hot topic among the public and designers now but also hoped to put the current interest in a broader context. As Imbert said, “the inter-relationship between food and the city has a long history.”

What’s “Rio+20″ and why should we care?

by

For those of us working in ecological and economic sustainability, Rio+20 is a big deal, and in our circles, just about everyone knows about it. Yet we have to wonder, what proportion of the general public has even heard of Rio+20, much less knows what it is? It’s a big question for a forum like the Daly News, where we’re all about mainstreaming sustainability. When we mention Rio+20, do we quickly lose readers who vaguely assume it’s some international, esoteric event with little relevance to mainstream society?

Updating world deepwater oil & gas discovery

by

Deepwater oil production will help reduce the decline in world oil production from aging fields. The IEA claims that four Saudi Arabias need to be discovered up to 2030 to replace the present decline in production (about 5 %/a). The deepwater ultimate is likely to represent less than half of Saudi Arabia’s oil ultimate. It is not enough!

Food’s critical path: review of “A Permaculture Handbook: Garden Farming for Town and Country” by Peter Bane

by

Peter Bane’s big idea here is not entirely original — Toby Hemenway, David Holmgren, and even the UN Rappoteur on Human Rights have written about it — but it is timely and Bane describes it with greater depth and practical guidance. The big idea is that creation of 21st century garden farms at all scales and in all locations — horticulture not agriculture — provides a serious, necessary challenge to 20th century factory farms.

An interview with Nick Shaxson, author of ‘Treasure Islands: tax havens and the men who stole the world’

This narrative that comes out of the city and is widely repeated, is demonstrably untrue. It is a much more complicated and nuanced picture than that. I would argue that if you have a system that remains unregulated and uncontrolled, you’re going to store up even bigger problems in the future. I think if you did start to regulate banks and banking properly, not just in an offshore sense but in terms of, you know, capital requirements and all sorts of other things, you would end up having a much stronger, much healthier economy. In fact, there is historical evidence to suggest that this is the case.
