In the arid plains of eastern Columbia lies the tiny village of Gaviotas, cut off from the outside by exceedingly unforgiving jungles, which also happen to be occupied by a bewildering variety of violent guerillas (NOT gorillas).
The book portrays a well nigh impossible scene there: natives, settlers, and alternative-development types using renewable energy, creative lo-tech engineering, and a culture of egalitarianism to find sustainable ways to thrive (for 50 plus years now) in the badlands of one of the most troubled countries in South America.
But its not flowers and rainbows and utopian rhetoric...its mostly an NPR-style description of a bunch of people who work hard, learn, invent tools and stuff (complete with blueprint illustrations) and fall in love with the place. Very good reads, as it were.
NB: Gaviotas bears a faint resemblance to America's Burning Man festival, i.e. it features people in an alternative community amidst an unhospitable environment. But there are significant differences between the two: Gaviotas is sustainable, practical, and features prominently in all sorts of UN Development Programme literature whilst Burning Man is an elaborate way for hippies in the richest country on earth to congregate, take drugs, and feel self-satisfied.
