This paper surveys the impact of the Green Revolution and the transformation of indigenous
farming communities through commodity-based food cultivation. Second, it reviews rural urban relationships over the limited natural resources necessary to sustain high levels of food
productivity. Third, it argues for a shift to organic farms, poly culture and other holistic
methodologies which sustain ecological integrity. Finally, a case study of the Sufficiency
Economy movement in Thailand sets the stage for a scenario of ecologically sustainable
bio regions composed of vibrant, healthy, and self-reliant food producing communities.
