The meaning of an expression resides not in the expression itself but in the experience of a person's engagement with it. Meaning will be different not only to different people but also to the same person at different times. This book offers a way of attending to these different meanings. This way (or method) is a version of a trans-cultural activity that Richard Dawson calls attunement. The activity of attunement involves a movement of self-adjustment to a language, which a person transforms in her or his use of it. Consciously performing the activity can enable understanding of the proces

A large number of operating, dormant, and abandoned minesites in Canada and the U.S. were visited in 1996 to gather information on closure planning practice and to observe the performance of reclaimed landscapes. Information was compiled from mine tours and through on-site interviews with reclamation and environmental personnel. Most Canadian mines are on the closure path and have completed their first conceptual closure plan, usually in response to new government regulations. However, there is considerable uncertainty regarding several key closure issues including certification, abandonment, long-term residual liability, financial assurance, and numerous technical issues. Most mining landforms are showing good performance in terms of physical stability and revegetation. However, there is some uncertainty regarding the long-term reliability and performance of some landforms, most notably constructed rivers, end-pit lake filling, and tailings slopes. Difficulty in prediction of the long-term performance of closure landscapes has, in part, lead to a certification barrier. Very few mines have requested or achieved certification of reclaimed land, despite the fact that certification is usually the stated objective of reclamation activity. Although most mine reclamation focuses on certification, a more strategic focus is required. The ultimate objective for mine reclamation should be custodial transfer of the land (to the crown or a third party), with certification being one step on the closure path. Due to the concerns about long-term liability for reclaimed sites, a transfership barrier exists and very little reclaimed mine land has been transferred to new owners. Landscape engineering (setting goals, designing for closure, using landforms and vegetation that have sustainable and reliable long-term performance) is perhaps the next major step in mine reclamation practice. Aspects of this approach have already been adopted by several mines and research is ongoing. ; Non UBC ; Unreviewed ; Other

AbstractFuture development in cities needs to manage increasing populations, climate‐related risks, and sustainable development objectives such as reducing greenhouse gas emissions. Planners therefore face a challenge of multidimensional, spatial optimization in order to balance potential tradeoffs and maximize synergies between risks and other objectives. To address this, a spatial optimization framework has been developed. This uses a spatially implemented genetic algorithm to generate a set of Pareto‐optimal results that provide planners with the best set of trade‐off spatial plans for six risk and sustainability objectives: (i) minimize heat risks, (ii) minimize flooding risks, (iii) minimize transport travel costs to minimize associated emissions, (iv) maximize brownfield development, (v) minimize urban sprawl, and (vi) prevent development of greenspace. The framework is applied to Greater London (U.K.) and shown to generate spatial development strategies that are optimal for specific objectives and differ significantly from the existing development strategies. In addition, the analysis reveals tradeoffs between different risks as well as between risk and sustainability objectives. While increases in heat or flood risk can be avoided, there are no strategies that do not increase at least one of these. Tradeoffs between risk and other sustainability objectives can be more severe, for example, minimizing heat risk is only possible if future development is allowed to sprawl significantly. The results highlight the importance of spatial structure in modulating risks and other sustainability objectives. However, not all planning objectives are suited to quantified optimization and so the results should form part of an evidence base to improve the delivery of risk and sustainability management in future urban development.

This volume details research underpinning the 'Coastal Simulator' developed by the Tyndall Centre for Climate Change Research. The Simulator provides a framework to analyze long term coastal evolution taking account of all the relevant factors. These include the uncertain future climate and other conditions, such as land use change and allows evaluation of diverse management responses. Coastal zones exemplify the environmental pressures we face: their beauty attracts settlement, they offer potential for diverse economic activities, and they are sensitive natural habitats for important species, as well as providing a range of ecosystem services. They are also extremely vulnerable to the vicissitudes of climate change, which include rising sea levels and changes in extreme events such as storms. With large populations living in coastal and estuarine cities facing the ongoing threat of inundation, coordinated management is essential, especially as coastal zones form a linked system in which piecemeal, uncoordinated management could be counterproductive. The Simulator's current detailed application to the Norfolk coast goes from global climate modelling and broad socio-economic change to the details of evolving coastal habitats, coastal erosion and coastal flood risk and their societal implications. This framework reflects the work of a multi-disciplinary team of key players who analysed these diverse factors in a coherent and integrated manner. The book offers a compelling synthesis of the lessons learned so far at national and international levels, drawing on the expertise of policy makers as well as respected figures in the field
