I think the information is now in the hands of the locals. An education campaign is underway. There is also an incentive program to allow ownership, so that the yield from the land will directly benefit the farmers and it will be in their self interest to use optimal farming practices.
Your point is well taken: In times of want, one doesn't worry about saving seed for the future, or preserving soil for next season. One worries about eating. Survival is a strong motivator.
I am totally for self help and learning how to cultivate nature with the least damaging methods. If this meets self interest, that is probably the best of combinations.
