Dimensions of Environmental Engineering

Abstract

The impact of human activity on the biosphere has produced a global society context in which scarcity of natu- ral resources and risks to ecological health such as air pollution and water contamination call for new solutions that help sustain the development of human society and all life on earth. This review article begins by recalling the historical and philosophical context from which contemporary environmental engineering has arisen as a science and domain of techno- logical development. Examples that deal with some of the core issues and challenges currently faced by the field, such as problems of scale and complexity, are then discussed. It is emphasized that the sustainability of the built environment de- pends on innovative architecture and building designs for optimal use and recycling of resources. To evaluate problems related to global climate change, storms, floods, earthquakes, landslides and other environmental risks, the behaviour of the natural environment needs to be taken into account. Understanding the complex interactions between the built envi- ronment and the natural environment is essential in promoting the economic use of energy and waste reduction. Finally, the key role of environmental engineering within models of sustainable economic development is brought forward.
