During the past 25 years the bauxite and alumina industry has grown threefold creating major change in the industry structure and reducing the dominance of the majors. Australia has emerged as the leading producer with a major third party alumina market developed principally by Alcoa of Australia. Future growth while, less dramatic, is likely to be substantial requiring US$50 billion to fund new projects which will be concentrated in developing countries with large bauxite reserves and developed infrastructure. 相似文献

ABSTRACTSmart and eco-cities have become important notions for thinking about urban futures. This article contributes to these ongoing debates about smart and eco-urbanism by focussing on recent urbanisation initiatives in Asia. Our study of India’s Smart Cities Mission launched under the administration of Narendra Modi and China’s All-In-One eco-cities project initiated by Xi Jinpin unfolds in two corresponding narratives. Roy and Ong’s [2011. Worlding Cities: Asian Experiments and the Art of Being Global. Oxford: Wiley-Blackwell] “worlding cities” serves as the theoretical backdrop of our analysis. Based on a careful review of a diverse set of academic literature, policy and other sources we identify five process-dimensions for analysing the respective urban approaches. We show how the specific features of China’s and India’s urban focus, organisation, implementation, governance and embedding manifest both nations’ approaches to smart and eco-urbanism. We argue that India’s Smart City Mission and China’s All-in-One project are firmly anchored in broader agendas of change that are set out to transform the nation and extend into time. The Indian Smart City Mission is part of a broader ambition to transform the nation enabling her “smart incarnation” in modernity. Smart technologies are seen as the key drivers of change. In China the framework of ecological civilisation continues a 5000-year historical tradition of civilisation excellence. By explicitly linking eco-urbanism to the framework, eco-cities become a means to enact ecological civilisation on the (urban) ground. 相似文献

The success of river and lake basin development and management is rooted in the knowledge of its resources, both physical and human. Within the framework of an integrated basin plan, each economic sector depends on the adequacy of such data for its individual development. The management and conservation of the basin itself in turn depends on knowing the requirements of those sectors and their probable impact on each other and on the status of the basin's resources, its ecology and environment. The development of African river basin resources is subject to various constraints, some for physical and climatic reasons, others tied to socio-cultural characteristics and the priorities of national economies. These are reflected in financial, manpower and institutional limitations, problems of finding technologies suited to specific local conditions and concern for human health. The scale and complexity of river basin development make it difficult to predict precise outcomes of planned proposals, but a progressive approach which links long-term activities with achievable, shorter term production projects offers prospects for ultimate success. 相似文献
