The Application of Science and Technology to Long-Range Solutions: Multiple Cropping Potentials
The focus of this book is not so much on national production goals as on the welfare of people. In most Asian countries rural inhabitants constitute from 50 to 80% of the national population. A great portion of these people have been touched only marginally, if at all, by recent advances under the green revolution, even though their countries may be approaching self-sufficiency in food. In most cases these bypassed farmers either lack the capability to adopt the new technology, or do not have the physical resources to justify high investment in a technology that, for them, has only moderate production potential. Multiple cropping, or the growing of more than one crop per year, is readily adapted to areas where resources are not limiting. Special techniques may be required to achieve extra high year-round productivity in labor-intensive systems, but the approach is for the most part straightforward, using a high-input, high-return technology. Our concern with rural welfare, however, directs our attention to the bypassed majority whose production resources are limited. It is for this group that multiple cropping technology can have the greatest impact in the future. It is toward this limited-resource sector that our attention as cropping systems specialists is more closely directed.
