In the past, environmental decision making has been based on analysis of policy options with respect to emission reduction, deposition or concentration of pollutants and the design of preventive strategies using disparate single-model and discipline results. It was impossible to obtain optimal...

The 1990 Canadian long-range transport of air pollutants and acid deposition report divided North America into 40 sources of emission and 15 sensitive receptor sites. For the purpose of national policy making and international negotiation, the use of these large sources and few receptors may...

In the past environmental management practices have been based on disparate analysis of the impacts of pollutants on selected components of ecosystems. However, holistic analysis of emission reduction strategies is necessary to justify that actions taken to protect the environment would not...

Decision support system often requires the combined knowledge of multiple domains. A knowledge-based approach is proposed to include not only the process modelling knowledge but also the descriptive knowledge in the integration. Descriptive knowledge such as survey statistics and expert opinions...

The purpose of this study was to examine interrelationship and causal linkages between socioeconomic and environmental variables in OECD countries. To aid this study, a LISREL modelling tool was implemented. The findings of the study indicated that gross public debt increases with deterioration...

VOCs and NOx are the primary precursors in the formation of ground-level ozone (SMOG). The rate of formation is a function of concentrations, temperature and sunlight strength. Both pollutants as well as the ozone itself can be transported over very long distances. Therefore, it can affect...

An aggregate measure of production efficiency involving crop and livestock enterprises is examined in the Selale and Ada regions of Ethiopia using Data Envelopment Analysis (DEA). In general, farmers in regions more suitable to crop production (Ada) tend to attain higher production efficiency...
