Abstract

Despite the difference in their populations and political status, New Caledonia and Papua New Guinea have comparable levels of economic dependence on the extraction and export of mineral resources. For this reason, the costs and benefits of large-scale mining projects for indigenous communities has been a major political issue in both jurisdictions, and one that has come to be negotiated through multiple channels at different levels of political organisation. The ‘resource boom’ that took place in the early years of the current century has only served to intensify the political contests and conflicts that surround the distribution of social, economic and environmental costs and benefits between community members and other ‘stakeholders’ in the large-scale mining industry. However, the mutual isolation of Anglophone and Francophone scholars has formed a barrier to systematic comparison of the relationship between large-scale mines and local-level politics in Papua New Guinea and New Caledonia, despite their geographical proximity. This collection of essays represents an effort to overcome this barrier, but is also intended as a major contribution to the growth of academic and political debate about the social impact of the large-scale mining industry in Melanesia and beyond.

Abstract

The book contains a collection of articles dealing with how the extraction of mineral resources can be considered in environmental analyses such as Life Cycle Assessment (LCA). The consumption of resources, e.g., metals, is increasing strongly worldwide. This is associated with more energy use; environmental pollution; and social, economic, and political consequences. An increase is also expected for the coming decades. At the same time, modern products and technologies, even in the field of renewable energies, require a large number of critical raw materials. A crucial question here is the exhaustibility of natural resources. What is the relevance of resource depletion today? Must a geological shortage of metals be expected in the foreseeable future? How could such a thing be considered in the LCA of products and weighed against other environmental aspects? The articles in question have been written over the past three years by leading experts in both geology and environmental sciences and show the breadth of the controversial discussion.

Abstract

The need for efficient and sustainable management methods of mine waste is continuously growing all around the world. These waste products often present serious management problems due to their more or less significant amounts and possible environmental threats. This Special Issue highlights the recent and new trends in sustainable mine waste management techniques. Currently, it is essential to sustainably manage mine waste, considering social, economic, environmental and technical aspects. In this Special Issue, insights related to the following issues are highlighted: the problems around mine waste, the fine characterization of mine waste, the latest available technical and environmental solutions to efficiently manage mine waste, including treatment and processing before disposal and high value element recovery, with the view of moving towards defining effective, low-cost and ecofriendly methods, the recycling of mine waste products as alternative resources in different sectors, and finally laboratory, pilot and/or industrial-scale studies related to these topics of research. Scientists and industry and governance stakeholders have to face these new challenges to find the best management practices for the future.
