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 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 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.

 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.

 the prevailing techniques of American agribusiness have focuses on the
substitution of capital for labor, in order to increase output per man-hour
and reduce the agency problems of labor—even at the cost of reduced output
per acre. 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.

 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."
