I would like to agree with both sides of this discussion. In Brazil, the drylands
occupy 900,000 square kilometers, 40% of which are in frank desertification. As
properties can be relatively large, a lot of this could be machine-swaled. Almost
every small town has at least one machine for taking care of the dirt roads which could
be used to do such work. So an enlightened mayor could help re-green a whole
municipality. I am always impressed how the slightest indentation in dry soil
accumulates material, water, and creates life, and we can think of using machines for
these, where overland runoff is intense ( although I have a personal aversion to
machines tearing the soil, it seems somehow to "hurt"). There is an argument for these,
where nature no longer has the vitality to regenerate spontaneously. But if there is no
change in people's way of seeing and working the land, especially in understanding and
respecting Natures intense efforts to restore and maintain balance, if there is no
change in the agricultural model ( which always implies a change in understanding and
ethics in so far as the land owner takes responsability for the health of his land) I
don't see much hope of real permanent progress..
