In coastal destinations climate change adaptation is needed to address coastal erosion due to a combination of sea level rise and more frequent extreme weather events leading to loss of natural features and tourism infrastructure. Managed realignment is increasingly adopted as a strategy to address coastal change; however, this has often proved a contentious strategy with stakeholder groups. This study explores tourists' representational framework of managed realignment and how this frames understanding of the concept, understanding of how coastal resources might change and implications for future visitation. Data compiled using a questionnaire adopted a social representations theory perspective to analyse how collective tourists’ ideas may serve to mobilise the public in various ways. In general tourists have a poor understanding of managed realignment anchored to historic coastal management strategies and contextualised by use values with consequent implications for tourism planning and coastal management decision making. 相似文献

Under the past Common Agricultural Policy (CAP) olive oil subsidy regime, farmers were eligible for subsidies on the basis of the amount of olive oil they produced. This led to an intensification of production, particularly on flat land, and had in most cases negative environmental effects, such as more soil erosion on sloping land and more pollution. With the decoupling of agricultural support under the newly established rules of the CAP, formalised in 2005, cross compliance measures have become obligatory.In this paper an ex-ante assessment is made of the application of cross compliance for soil erosion control (natural cover crops and terrace maintenance) in hilly and mountainous olive groves in Trás-os-Montes in Portugal. A linear programming model was developed to assess the various socio-economic and environmental effects of four different development scenarios for olive groves. The scenarios were developed on the basis of changing market prices, wage rates and subsidies; their effects included shifts towards intensification, abandonment and organic farming. Simulations considering a minimum return to labour constraint showed very high levels of abandonment, particularly in combination with cross compliance obligations. However, even without this minimum return to labour constraint, abandonment would reach more than 20% in three out of the four scenarios. The model showed that cross compliance obligations could be quite effective in reducing erosion, but that they would depress income in all scenarios as a result of higher abandonment and lower percentage shifts towards intensive systems. 相似文献

This paper explores the effects of debt erosion on the market process. Debt erosion is the attempt by government to lower the real value of its debt through the creation of unexpected inflation. In addition to the costs recognised by most economists, debt erosion through unexpected inflation can impair the price system's ability to coordinate exchange activity and can result in costly capital misallocations. This is because the creation of unexpected inflation implies disequilibrium in the money market. To avoid the harm from such monetary shocks, this paper suggests a separation between money and state, enshrined in an explicit rule at the constitutional level. 相似文献

随着数字经济的发展,从前制定的税收原则已经不再适用,税基被侵蚀已经是各国之间的共识.事实上,国与国之间争夺的只是征税权,以便获得更高的税收收入.例如法国、英国强调用户所在地创造的价值,实际上是为了把税收留在境内,而美国对此政策的不满也反映了这样的政策会对其造成收入流失.于是各国纷纷推出诸如“补丁型”税制、“实质认定型”... 相似文献
