The Time Horizon in the Evaluation of sustainable Development

引用

Journal of Civil Engineering and Architecture 2012年第3期6卷 334-343页

作者： Manila De Iuliis Peter Brandon Building and planning Office Town Hall Lungomare D 'Albertis 4 Santo Stefano al Mare Imperia Italy School of the Built Environment University of Salford UK

Current methods of evaluating long term sustainable Development seldom take into account the time period over which an evaluation is made except through simplistic economic models which heavily discount the future. If sustainable development is to be a serious issue then the impact on the future of decisions made today must be properly assessed and evaluated. This requires a new understanding of time as a key feature of the Sustainability debate and new models of how this new understanding can be brought into the evaluation process. This was at the heart of the Torino declaration signed by the University organisations of the G8, G20 and developing nations in April 2009. Time is a critical part of the sustainability debate and is seldom addressed directly. This paper will provide a possible solution based on a strong theoretical and philosophical framework of how this difficult subject can be approached and applied to sustainable urban planning. The work presented is based on a philosophical model of the cosmos which has both internal and external credibility. It forms the basis ofa PhD study and has been applied to small case studies in Italy and elsewhere. These will be presented to encourage further study into this important area within the evaluation and assessment of sustainable development.
