Environmental policies in agriculture have now been fully incorporated into policy throughout Europe both within and outside of the European Union. One of the cornerstones to the successful implementation of these policies is both the willingness and ability of farmers to implement them. Many actors influence both the formulation and implementation of such policies, from governments, through pressure groups and the agricultural knowledge networks (AKNs) in various countries, to farmers themselves. In assessing the principal objectives of all of these actors, it can be seen that none has environmental goals as their principal objective, and the development of policies is thus both difficult and a residual priority. This situation is likely to be ameliorated not through a focus on more effective policy instruments for agri-environmental polices, but through adjustments of administrative structures for both their development and in carrying them out. 相似文献

The site of Combe-Grenal is arguably the reference site for the Mousterian of southwest France. Bordes excavated the site over a period of 13 years and generated a large collection of lithics and fauna from a deep series of 64 Lower and Middle Paleolithic levels. Though Bordes only partially published his work at the site, its long stratigraphic sequence and particularly its collections have been subjected to numerous studies over the years and have figured prominently in several long-running debates concerning the Mousterian. Recently, the authors undertook a project to inventory and analyzed these collections along with the documentation of their archaeological context. In so doing, however, a number of serious problems became apparent with the collection in its current state, problems that cannot easily be resolved given the state of the available documentation. These problems have important implications not only for results of studies based on these collections, but more generally, they also point to problems in terms of how archaeological collections are curated. 相似文献

自1952年以来,被揭取迁移到博物馆中的墓葬壁画,在被修复、收藏、展示、运输、研究的过程中出现了画面污染、色彩褪变、颜料层粉化脱落、地仗层空鼓、支撑体变形等中度或重度腐蚀受损现象,使得现阶段对导致壁画藏品劣化、损毁的风险因素进行梳理和调查成为了一项亟待开展的基础工作。为此本工作从壁画保护的视角出发,在充分考虑其本体脆弱性的同时,将藏品管理中潜在的不确定性识别为明确的风险因素,提出有针对性的预防性保护措施,在规避风险的同时延缓藏品的老化进程,为加强藏品保护和零风险管理提供参考。 相似文献

Pre‐Romanesque murals at Kosto?any pod Tríbe?om, Slovakia, have been investigated by portable X‐ray fluorescence and by microanalytical methods to identify painting materials (pigments and binders), and to explain the degradation of colours. Today, missing green and blue shades have been reconstructed according to residual concentrations of Cu, which correspond to copper chlorides—products of salt corrosion of the copper carbonates azurite and/or malachite, accelerated by micro‐organisms. As confirmed by powder X‐ray microdiffraction, original minium (Pb3O4) has been transformed to brown–black plattnerite (PbO2). In increased humidity, even insoluble pigments are washing down from the walls and the intensity of colours further diminishes. 相似文献
