I first became interested in the methods of planning the sequence and timing of jobs on large-scale development projects, as a field officer involved in planning and implementing mechanised farming schemes in Uganda in the mid-sixties.
The Society of Environmental Geochemistry and Health (SEGH) Second International Conference on Arsenic Exposure and Health Effects was held June 12-14, 1995 in San Diego, California.
The Upper Adriatic Sea basin comprises a very precarious coastal environment subject to continuous changes which prove appreciable not only over the geological scale but also in historical and modern times.
Recent studies on diverse aspects of the biology of clitellate works (oligochaetes and leeches) are found in the Proceedings of the most recent International Symposium on Aquatic Oligochaete Biology - from development to population dynamics and from ultrastructure to evolution.
Members of the family Littorinidae are among the most widely studied gastropod molluscs and the more questions we answer about this group, the more questions are inevitably posed.
Environmental Contamination and Remediation Practices at Former and Present Military Bases outlines the different strategies that are useful in the investigation and subsequent remediation of military bases, Particular attention is paid to the pollution of groundwater.
The increasing concern over environmental and health impact of urban air pollution has lead to a growing need for an international conference focussing specifically on urbanised regions.
The Environmental Monitoring and Assessment Program was created by EPA to develop the capability for tracking the changing conditions of our natural resources and to give environmental policy the advantages ofa sound scientific understanding of trends.
A comprehensive source book for anybody interested in the potential of remote sensing and GIS technology for the Eastern Europe countries in transition, and less developed countries in general.
The monitoring of point sources by the Environmental Protection Agency (EPA), the states, and the tribes has documented and helped reduce the levels of chemical stressors affecting our ecosystems.
Agriculture is a crucial component of the economies of many of the countries in transition from a centrally-planned to a market economy and the sector is by no means immune to the environmental and socioeconomic problems confronting the countries as a whole.
The patterns of land use that have evolved in Europe reflect the boundaries set by the natural environment and socio-economic responses to the needs of the population.
The main subject of the Workshop was the new developments about the cost effective treatment techniques for better removal efftciencies and dis- cussion of policies for pollution control.
3 new biota and extinction of others, and extensive soil erosion reaching almost catastrophic proportions have led to desertification of many upland areas and abandonment by local populations.
Sun, wind and water draining from the land interact with the morphological features of a water body to create the environment experienced by freshwater plants and animals.
The Joint Research Centre of the European Communities, and in particular the Institute for Systems Engineering and Informatics (ISEI) at Ispra, have weil established competences in risk analysis, uncertainty analysis and statistical data treatment.
Towards the Balance and Management of the Carbon Budget of the Biosphere The current state of misunderstanding of the global C cycle and our failure to resolve an issue that has been debated for 100 years (Jones and Henderson-Sellers, 1990) speaks loudly about the limitations of modem science when faced with the complexity of the biosphere.
Air pollution has historically been viewed as a local or regional scale problem with attention focused on acute episodes such as the sulphur dioxide and smoke smogs of London in the 1950s and 1960s and the photochemical smogs of southern California first recognized by Haagen- Smit in the early 1950s.
than 6,000 hectares of arable land turn The second half of the twentieth century will pass into history as an epoch that saw great irreversibly into desert (Tolba, 1992).
In 1962 Rachel Carson warned of the consequences of man's pollution in her book Silent Spring, a book that some feel marks the real beginning of our environmental awareness.
The climate of the Earth has undergone many changes and for those times when geologic data are widespread and abundant the Mesozoic appears to have been one of the warmest intervals.
Only a few laboratories in the world have taken the bold step to attempt the integration of sub-models of the climate system, the global biogeochemical cycles and the human/societal components.
Since the mid-seventies, electric utilities were faced with escalating construction costs, growing environmental plus siting constraints and increasing uncertainty in demand forecasting.
