Research report on the severe ecological consequences of the defoliation program by American military forces in Vietnam. A significant fraction of mature trees in most forests are killed by single application of herbicides and almost completely killed by repeated sprayings. AAAS is urged to set up an international research program on the…

It is reasonable to suppose that a strong social science research program could have provided a source of knowledge whereby the impact of the agricultural revolution could have been cushioned for rural people. (Author/DF)

Comments on the banning of agricultural uses of DDT, the exceptions to the uses of DDT, and the role of the Environmental Defense Fund in the decisions. (AL)

Presents evidence suggesting that the longer-term biological effects resulting from climactic changes may be at least as serious as the immediate ones. Primarily considers results of a nuclear war in which sufficient dust/soot are injected into the atmosphere to attenuate most incident solar radiation. (JN)

Assesses the current status of science and technology in India, focusing on developments in agriculture, energy, medicine, space, basic sciences, and engineering. Indicates that although India has benefited in many fields from international collaboration during the last 30 years, the country's leaders have also placed particularly strong emphasis…

Discusses: (1) the synergistic nature of science, technology, and engineering; (2) the benefits and burdens of technology; (3) the resolution of societal issues; and (4) the roles and responsibilities of scientists and engineers in the resolution of societal issues. (JN)

The development of fuels from biomass can lead naturally to dispersed facilities that incorporate food or materials production (or both) with fuel production. The author analyzes possible systems based on sugarcane, corn, and guayule. (Author/MA)

Examines increases in food production and relates these to population growth. Compares per capita food production increases in the developed versus developing nations. (GS)

The dichotomy existing between fundamental and applied research in agriculture inhibits progress in theory and practice. Suggests that the initiative for breaking down the barriers between applied and fundamental research should come from working scientists. Lists ten agriculturally relevant fundamental research areas which are lagging and require…
