The degradation of marine and coastal ecosystems has given rise to the creation of specific protection rules. The Marine Strategy Framework Directive and the Water Framework Directive are the standards agreed in the European Union with the aim of obtaining a good ecological status in marine and coastal waters by applying a programme of measures, if necessary. These measures must be technical, social and economically feasible, in such a way that costs do not exceed benefits. This work expounds the implementation of two economic tools to assess the programme of measures intended for the environmental restoration of one of the most important coastal ecosystems in Europe, the Mar Menor coastal lagoon (SE Spain). Thus, the cost–benefit analysis (CBA) (and its extensions) and the contingent valuation method are used to assess the aforementioned programme in terms of economic and environmental profitability. Results prove the socioeconomic and environmental profitability of the actions due to be undertaken, with rates of return of around 10%. From a methodological point of view, there is a clear need to widen the classic CBA scheme by using the extended CBA and the dual CBA to gauge this type of environmental restoration actions.  相似文献

Recent excavations at Palù di Livenza (northeastern Italy) revealed a multiphase Neolithic pile dwelling dated between ca. 4,300/4200 and 3,600 cal BC. Three lumps with teeth imprints and a larger amorphous piece from the Late Neolithic layers have been studied by X-ray computed micro-tomography (microCT) and synchrotron Fourier-transform infrared spectroscopy (FTIR). FTIR spectra match well that of birch bark tar and microCT of the larger piece has revealed a rolled-up structure likely corresponding to bark rolls. The lumps of birch pitch were probably chewed to soften the tar prior to be used as hafting adhesive or therapeutic substance. The rolled-up inner structure of the larger piece and the remains of birch bark tar and abundant charcoals on its surface suggest it probably corresponds to a rare waste product from allothermic tar production.  相似文献

This paper analyses the new rent seeking strategies in housing implemented during Spain’s financial crisis. The Spanish Model presents a paradigmatic case of the need for capital to reinvent itself through the articulation of new mechanisms for the production and appropriation of urban rent, as the crisis revealed the limits of strategies that were implemented during the bubble period. Amongst these new strategies, the paper analyses the rescue of financial entities, the creation of a ‘bad bank’ and the establishment of Spanish REITs. These mechanisms are leading to financialisation of rental housing and the emergence of vulture funds as new transnational owners of housing.  相似文献

The State Archive of the Russian Federation (GARF) contains a corpus of around one hundred letters sent by Élisée Reclus to Pëtr Kropotkin between 1882 and 1905. The correspondence is mainly concerned with their geographical works, notably the collaboration of Kropotkin with the Nouvelle Géographie Universelle (1876-1894) and the Brussels edition of Kropotkin’s Orographie de la Sibérie (1904), edited by Reclus. In this paper, we deal first with the importance of this source: it is an example of the material work of a network of geographers who were at the same time the founders of the international anarchist movement. We suggest the correspondence falls into two parts: the first period (1882-1886) when Reclus was in exile in Switzerland after the Paris Commune of 1871, and Kropotkin was in prison in France; and the second period (1888-1905) when the two anarchist geographers discuss the role of geographical education, historical geography in Europe and its part in the globalisation of their era. The archive also contains significant evidence of their relationships with British geography: Kropotkin lived in London and joined the Royal Geographical Society and was on familiar terms with leading Fellows, such as John Scott Keltie and Halford Mackinder. The paper addresses the significance of the correspondence for understanding the relationships between geography, politics and public education, and the role of these heterodox geographers in the construction of geographical knowledge. The paper is accompanied by the publication, for the first time, of an edited selection of the letters.  相似文献
