Towards a deeper and broader ecological footprint
More details?
Sustainability has become one of the expected competencies for the civil engineer. Embedding sustainability into practice constitutes a burden of responsibility, yet an opportunity to provide leadership. It is one of those subjects that we cannot afford to ignore.
ICE Proceedings: Engineering Sustainability provides a forum for sharing the latest thinking from research and practice, and increasingly is presenting the 'how to' of engineering a resilient future.
It features refereed papers and shorter articles relating to the pursuit and implementation of sustainability principles through engineering planning, design and application. The tensions between and integration of social, economic and environmental considerations within such schemes are of particular relevance. Methodologies for assessing sustainability, policy issues, education and corporate responsibility will also be included.
The aims will be met primarily by providing papers and briefing notes (including case histories and best practice guidance) of use to decision-makers, practitioners, researchers and students.

A revised methodology for calculating ecological footprints is proposed. The method considers anthropogenic disturbances at a finer level of geographical desegregation than previous methods; instead of a single national land area it considers 1408 smaller regions within Australia. It also addresses a previous gap in disturbance-based ecological footprint calculation, that is, the exclusion of ecotoxic emissions. The method is described and illustrated using a case study. The resulting ecological footprint is larger than previous calculations, but it avoids a current methodological problem in which the energy used to treat exhaust gases or wastewaters increases the ecological footprint of communities without any corresponding benefit associated with reduced emissions to the environment.
