Abstract
The world food system must undergo significant transformation and expansion if it is to meet demands for food projected through the coming century and beyond. At current rates of agricultural expansion massive food shortfalls will occur at different times, in different places, in different commodities — affecting different population groups. Current strategy for expansion of world food production, adopted by the recent United Nations World Food Conference (November 5th–16th, 1974) calls for a largescale horizontal and vertical development of conventional agricultural practices, leading nearly to a doubling of world food production within the next 25 years. In the face of energy, materials, water and land shortages this goal will be elusive. If the food production goals for the next quarter century are met through an expansion of conventional agricultural practice, an already serious process of environmental degradation will be radically aggravated. While it is to soon to suggest that within this period the process will be of crippling magnitude, it is certain that in the areas of soil erosion and salinization, eutrophication, and dispersal of unused fertilizers, enduring pesticides, and other substances, increased damage from agricultural pollution may be expected, as well as decreased or impeded yields. In both the developed and developing countries abatement costs will be large, and in some cases prohibitive. Target goals for the expansion of the world's food supply into the next century inevitably involve radical social, economic and technological change. If such expansion threatens to impose massive burdens upon the ecosystem the process of rationalization that must underlie the expansion also offers the chance of integrating into it sound ecological practices.
