Decoupling of Economic Growth and Material Consumption is an Illusion, Researchers Say

“Metrics on resource productivity currently used by governments suggest that some developed countries have increased the use of natural resources at a slower rate than economic growth (relative decoupling) or have even managed to use fewer resources over time (absolute decoupling). Using the material footprint (MF), a consumption-based indicator of resource use, we find the contrary: Achievements in decoupling in advanced economies are smaller than reported or even nonexistent.”

“By calculating raw material equivalents of international trade, we demonstrate that countries’ use of nondomestic resources is, on average, about threefold larger than the physical quantity of traded goods. As wealth grows, countries tend to reduce their domestic portion of materials extraction through international trade, whereas the overall mass of material consumption generally increases.”

“Our findings call into question the sole use of current resource productivity indicators in policy making and suggest the necessity of an additional focus on consumption-based accounting for natural resource use.”

Is Cuba the First Large-Scale Maker Society?

“When the U.S. left Cuba in the 1960s, it took most of the Cuba’s engineers with it. In their absence, Fidel Castro encouraged citizens to learn how to make their own stuff. So, they did. And, in the 70s, a culture of garage innovation was born from the revolutionaries, scientists, mechanics, and ordinary folk who formed the National Association of Innovators and Rationalizers (ANIR).”

Update: The book “Con nuestros propios esfuerzos” (“With our own effort”), released in 1991 by Verde Olivo, the publishing house of the Cuban Revolutionary Armed Forces, is available as a PDF. This 300-page long compendium describes and illustrates in technical detail a vast array of artificats, recipes, and survival strategies collected from all over the island by local authorities. Read more about it here (starting at page 4). Thanks to Michele.

The Energetic Implications of Energy Storage

“When renewable energy sources such as solar and wind farms generate more electricity than consumers need, storing the excess doesn’t always make sense. Large, grid-scale batteries capable of storing the extra electricity are resource-intensive and costly to manufacture and maintain — sometimes more so than the energy they’re used to store.”

Our Right to be Outside: Three Mules

“You spot a somewhat disheveled man with three fully loaded pack mules walking though your community. What the … ?

This strange and, to many, awe-inspiring sight has been experienced by thousands of people in small towns and large cities throughout the western United States. But who is he and what is he doing? Is he lost in the wrong century? Is he homeless? Is he on a mission?

mulesThe Mules (as he refers to himself and the animals collectively) have traveled for nearly three decades through 16 states. For the last ten years they have lived outdoors. Even though he may not talk much when one first meets him, if the time and place are right, Mule will share something that he feels we should all be thinking about.

Throughout their travels, the Mules have noticed an ever increasing urban sprawl. Open spaces where they once moved through freely, and sometimes spent the night in a secluded spot, were disappearing. More and more cars filled up the roadways, and the expanding urban infrastructure seemed to serve one purpose: accommodate more automobiles.

At the same time, space for other means of self- transportation, such as bicycling, horseback riding and simply walking, were shrinking. Those alternative means of self-travel have often been confined to designated “recreation” areas. Also, as the urban environment exploded, natural habitats have vanished, or been “preserved” in spaces a fraction of the size they once were.
Mule sums it all up: “The space needed by The Mules to travel this country freely in all four directions on the landscape is being taken over by the suburban model of automobile usage, exclusively, and leaving no space for alternative venues of moving and living. In our travels, we carry that awareness and bring it to others. We’re a working model for that awareness, one step at a time, all day, every day.””
