Economies of Scope

Posted by on 15 Mar 2011 | Tagged as: food, organics

The last two centuries of human evolution have been driven by “Economies of Scale”. Bigger is better, centralized infrastructure and distribution. My friend Gunter Pauli suggests a different model for the 21st century and beyond based on the notion of “economies of scope”:

Fish is healthy and proteine rich, but human appetite can hardly be satisfied only with fish caught from the oceans. On the other hand, the many fishes squeezed together in aquaculture lead to eutrophication of the ponds and surroundings due to the high amounts of fish feed and feces.

China has a long tradition of sustainable aquaculture. Professor George Chan has studied the production methods in the rural areas of his homeland and learned how to combine fish ponds and piggery in an intelligent manner. The pig maure is lead through algae ponds where benthos and plancton is raised which serves as feed for the fishes. The grass on the dikes is used as animal feed as well.

The result is a cycle of nutrients which involves all five kingdoms of nature. Without any additional fishfeed, the productivity achieved is lower if you only account for fish, but as there is also pork and vegetables, the business is competitive and economically sustainable. A new aquaculture model which uses economies of scope: This is how Blue Economy works.

How to Get Started in the Slow Food Movement

Posted by on 18 May 2008 | Tagged as: food

Nothing is more fundamental to sustainability than food. Thanks to a link passed on by my friend Ben de Vries, I recommend checking out the growing Slow Food movement:

Slow Food is good, clean and fair food. We believe that the food we eat should taste good; that it should be produced in a clean way that does not harm the environment, animal welfare or our health; and that food producers should receive fair compensation for their work.

Every day presents multiple opportunities to slow down and taste real food. Try it today!

For Your Calendar: Slow Food Nation

Posted by on 01 Feb 2008 | Tagged as: events, food


As a kid I tended a sizable vegetable garden. I don’t know what inspired me (a suburban kid) to till the backyard soil at age 10. But I loved the work and the joy of fresh, local food stuck with me. It was also the beginning of my entrepreneurial life as I sold produce to neighbors.

So today I was pleased to hear from my friends at Straus Communications that Slow Food Nation is coming to San Francisco later this year.

Most people have lost touch with food and farms, and this event will create a space in which we can celebrate, explore, and educate ourselves about food that is delicious, ecologically sustainable and socially just.

Slow Food Nation inspires and empowers Americans to build a food system that is good, clean and fair.

The world’s most pressing questions regarding health, culture, the environment, education, social justice and the global economy are all deeply connected to the food we eat and how it is produced.

Slow Food Nation is an event at the center of a movement with national impact and global implications. It will engage tens of thousands of attendees in learning how everyday choices affect our wellbeing, our culture and the health of the planet.

The event will be held from August 29 to September 1, 2008 in San Francisco, and will bring hundreds of farmers and food artisans from across the country to present an extraordinary range of foods and preparation techniques. It will offer activities for all ages, including food, music, talks, forums, workshops, films and exhibits, all highlighting food that supports an agricultural system that is good, clean and fair.
