    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract A detailed nitrogen budget was devised for agricultural activities in the Florida peninsula, based on routine data published by state agricultural agencies. The model demonstrates that important unmonitored fluxes of nitrogen can often be calculated by mass balance on individual model compartments, and that the reasonability of poorly quantified fluxes can be assessed. The results of such models can be very useful in designing and assessing the results of field experiments and in prioritizing environmental monitoring programs.

    Notes: Abstract The characteristics and role of the family farm have profoundly influenced the quality of human ecology. Considerable debate exists about the role of the family farm in the United States. This article attempts to clarify aspects of this debate by: (a) examining various definitions of the family farm and the conclusions that flow from these definitions, (b) presenting results of a structural analysis of American agriculture to better understand the origins of the debate and the relationship between people and agriculture, and (c) discussing the relevancy of some data and concepts used in evaluating the consequences of the structure of the agricultural sector.

    Notes: Abstract The Food and Agriculture Organization's (FAO) land evaluation methodology provides a procedure for assessing the suitability of land units within a study area for different land uses. This article describes the use of theLuplan computerized land-use planning package to provide an explicit means to select the land use for each land unit which best satisfies defined policies. The use of the package is demonstrated in a study that allocated multiple use activities within a native forest.

    Notes: Abstract The recent events at Chernobyl have again brought the issues of nuclear safety to the forefront of the nuclear power debate. Fortunately, our experience with such incidents has been very limited, but it is important to learn as much as possible from such events so as to minimize the cost and effect of any other nuclear incidents, be they small or large. Much of the discussion about the possible effects of nuclear incidents has centered around the human cost in terms of health. While this is undoubtedly of paramount concern, the effect of the release of radiation from Chernobyl on the agricultural resource base in Europe can provide valuable insights on how to reduce the costs associated with the contamination of agricultural areas. This article outlines some of the lessons that can be learned using the livestock-raising industry in northern Wales as an example.

    Notes: Abstract Agricultural runoff affects many streams in North Carolina. However, there is is little information about either its effect on stream biota or any potential mitigation by erosion control practices. In this study, benthic macroinvertebrates were sampled in three different geographic areas of North Carolina, comparing control watersheds with well-managed and poorly managed watersheds. Agricultural streams were characterized by lower taxa richness (especially for intolerant groups) and low stability. These effects were most evident at the poorly managed sites. Sedimentation was the apparent major problem, but some changes at agricultural sites implied water quality problems. The groups most intolerant of agricultural runoff were Ephemeroptera, Plecoptera and Trichoptera. Tolerant species were usually filter-feeders or algal grazers, suggesting a modification of the food web by addition of particulate organic matter and nutrients. This study clearly indicates that agricultural runoff can severely impact stream biota. However, this impact can be greatly mitigated by currently recommended erosion control practices.

    Notes: Abstract The right to eat and to an adequate standard of living for everyone motivates agricultural research assistance to developing countries with the primary objective of assuring sufficient food supply. This article focuses on aspects of food production and related agricultural research with specific examples from animal production. It discusses ethics of agricultural research in light of the utilitarian theory and compares livestock production in developing and developed countries. Major reasons for low outputs of animal production in developing countries are identified, and the potential for increasing the productivity of original, extensive production systems is evaluated. The article reviews the current status of biotechnology in developing countries and discusses several advanced animal technologies. The conclusions emphasize the need to involve local professionals in all phases of research and technology transfer in developing countries, avoidance of research that may worsen the situation of the recipients, sustainability of production systems, and the need for detailed assessment of potential impacts of technology on recipients.

    Notes: Abstract Results of recent ethnographic research in indigenous agricultural systems in the South American tropical forests indicate that the Geertzian model of the highly intercropped swidden that mimics the tropical forest it replaces is not the appropriate description of the agricultural regimes of several rainforest peoples. A model is proposed relating degree of intercropping to amount of agricultural labor.

    Notes: Abstract The proposition that tropical forest swidden gardens mimic the extraordinary species diversity of the forest by the use of extensive intercropping is examined in the light of the field architecture of the Barí, a people of the Maracaibo basin. Barí fields manifest annular zonation rather than intercropping. It is concluded that Barí horticulture is an inversion of the jungle rather than an imitation of it.

    Notes: Abstract This article documents, in the cases of Libya and Egypt, situations that occur in many other nations: conversion of farmlands to nonagricultural uses, exhaustion of nonrenewable water resources, irrigation leading to waterlogging and salinization of agricultural lands, development that does not benefit people in the regions being developed, etc. It is suggested that use of natural resources should be in accord with nationally determined priorities and should occur in a sustainable manner.
