quizas a algunos les interese esto- agricultura sustentable
copiado de ox You should have a look at Kevin Carson's Organization Theory, a really good study showing the weaknesses of the industrial model in terms of sustainability, and how the full force of state intervention is needed to keep it viable I also notice you are not informed about recent comparative studies on organic/sustainable vs. industrial agriculture, so here is some material First, here is what happens when you step away from the industrial model: http://www.rimisp.org/getdoc.php?docid=6440 "While 25% of projects reported relative yields > 2.0, (i.e. 100% increase), half of all the projects had yield increases of between 18% and 100%. The geometric mean is a better indicator of the average for such data with a positive skew, but this still shows a 64% increase in yield." THE KEY STUDY IS: Organic farming can feed the world, U-M study shows<http://www.ns.umich.edu/htdocs/releases/story.php?id=5936> PEOPLE 22 <http://delicious.com/url/f55dffc4fb32f79836a384d1f301a861> Organic farming can yield up to three times as much food on individual farms in developing countries, as low-intensive methods on the same land—according to new findings which refute the long-standing claim that organic farming methods cannot produce enough food to feed the global population. Researchers from the University of Michigan found that in developed countries, yields were almost equal on organic and conventional farms. In developing countries, food production could double or triple using organic methods covering that specific argument: small farms are more productive per acre<http://www.foodfirst.org/pubs/backgrdrs/1999/w99v6n4.pdf> PEOPLE 2 <http://delicious.com/url/4a555ba4fca79b572d2df8d0135ebefd> small farms produce far more per acre or hectare than large farms. One reason for the low levels of production on large farms is that they tend to be monocultures. The highest yield of a single crop is often obtained by planting it alone on a field. But while that may produce a lot of one crop, it generates nothing else of use to the farmer. In fact, the bare ground between crop rows invites weed infestation. The weeds then make the farmer invest labor in weeding or money in herbicide. food supply: small farms generate $1,400 per acre; large farms only $39 an acre - Global Swadeshi< http://www.globalswadeshi.net/forum/topics/2097821:Topic:112?page=2&commentI...
Small is Beautiful: Evidence of Inverse Size Yield Relationship in Rural Turkey <http://www.policyinnovations.org/ideas/policy_library/data/01382> PEOPLE 3 <http://delicious.com/url/392eb56a871348a5010b60a3ed115546> A strong inverse-size relationship between farm size and yield is prevalent in all seven regions of Turkey even though heterogeneity among households and regions is considered.

And small-scale operations, accordingly, tend to have both lower outputs per labor-hour and higher outputs per acre than large ones. What’s more, it’s simply incontrovertible that the most intensive organic techniques produce far more per acre than conventional agribusiness. For example, John Jeavons’ raised bed technique can feed one person on a minimum of 4000 sq. ft. That’s one tenth of an acre. And it’s done, by the way, without cattle manure or additional land for foraging them.

PEOPLE 4 <http://delicious.com/url/de4f832623341a3f940111dda02797b6> Dave Smith is excerpting from a book that exposes the big lies about Industrial Agriculture. "World hunger is not created by lack of food but by poverty and landlessness, which deny people access to food. Industrial agriculture actually increases hunger by raising the cost of farming, by forcing tens of millions of farmers off the land, and by growing primarily high-profit export and luxury crops."
