    Soil biodiversity: functions, threats and tools for policy makers

    Get PDF
    Human societies rely on the vast diversity of benefits provided by nature, such as food, fibres, construction materials, clean water, clean air and climate regulation. All the elements required for these ecosystem services depend on soil, and soil biodiversity is the driving force behind their regulation. With 2010 being the international year of biodiversity and with the growing attention in Europe on the importance of soils to remain healthy and capable of supporting human activities sustainably, now is the perfect time to raise awareness on preserving soil biodiversity. The objective of this report is to review the state of knowledge of soil biodiversity, its functions, its contribution to ecosystem services and its relevance for the sustainability of human society. In line with the definition of biodiversity given in the 1992 Rio de Janeiro Convention, soil biodiversity can be defined as the variation in soil life, from genes to communities, and the variation in soil habitats, from micro-aggregates to entire landscapes.

    Survey on Additive Manufacturing, Cloud 3D Printing and Services

    Cloud Manufacturing (CM) is the concept of using manufacturing resources in a service oriented way over the Internet. Recent developments in Additive Manufacturing (AM) are making it possible to utilise resources ad-hoc as replacement for traditional manufacturing resources in case of spontaneous problems in the established manufacturing processes. In order to be of use in these scenarios the AM resources must adhere to a strict principle of transparency and service composition in adherence to the Cloud Computing (CC) paradigm. With this review we provide an overview over CM, AM and relevant domains as well as present the historical development of scientific research in these fields, starting from 2002. Part of this work is also a meta-review on the domain to further detail its development and structure

    Economic valuation of marine and coastal ecosystems: is it currently fit for purpose?

    In this paper, we consider whether the current “state of the art” of environmental valuation is suitable for producing policy-relevant estimates of the benefits or costs of changes in marine and coastal ecosystems. We review recent changes in European legislation which has meant an increasing demand for economic valuation from the policy and regulatory community. The next section considers, at a more conceptual level, whether the economic “toolbox” and scientific evidence is up to the task of meeting the demand for more evidence-based policy. Finally, three case studies are used to explore the nature of the valuation task and review what is currently known. These case studies are of salt-marsh restoration, marine renewable energy investments, and deep sea conservation

    The Optimal Employment of Supply Chain management Decision Support Agents: an Exploratory Study

    Get PDF
    The issue of interest here is the employment of decision support agents in supply chain management. The study discusses the sorts of supply-related managerial tasks that decision support agents have been assigned, and how well or poorly they have performed these tasks. This research suggests the reasons why organizations might elect to invest supply chain management responsibilities in decision support agents rather than human functionaries. Finally, this research concludes by presenting a best fit construct for optimal decision making opportunities
