Two years of experience with EIA in Flanders (northern Belgium) was evaluated in order to gain perspective on the effectiveness of the administrative procedure. The four essential characteristics of the EIA procedure that were evaluated are: completeness, open and public character, objectivity, and verifiability. Representatives of all parties involved in the EIA procedure were interviewed. The result of the evaluation is a list of major problems with EIA. Recommendations for a more efficient procedure are suggested at a time when a proposal for a new, comprehensive, and permanent EIA decree is being discussed. The evaluation of the administrative procedure for EIA in Flanders shows that several vital characteristics of the EIA procedure are lacking. This reduces the obligatory and open nature of the process, resulting in insufficient guarantees that the environment receives the altention it deserves during the decision-making process.  相似文献

In geostatistics, both kriging and smoothing splines are commonly used to generate an interpolated map of a quantity of interest. The geoadditive model proposed by Kammann and Wand (J R Stat Soc: Ser C (Appl Stat) 52(1):1–18, 2003) represents a fusion of kriging and penalized spline additive models. Complex data issues, including non-linear covariate trends, multiple measurements at a location and clustered observations are easily handled using the geoadditive model. We propose a likelihood based estimation procedure that enables the estimation of the range (spatial decay) parameter associated with the penalized splines of the spatial component in the geoadditive model. We present how the spatial covariance structure (covariogram) can be derived from the geoadditive model. In a simulation study, we show that the underlying spatial process and prediction of the spatial map are estimated well using the proposed likelihood based estimation procedure. We present several applications of the proposed methods on real-life data examples.  相似文献

In this paper we examine how Canadian and Flemish municipalities manage and measure sustainable development initiatives. First, we present information on how Canada, Belgium and its Flemish region introduce sustainable development initiatives at the federal and regional levels of government. The introduction at municipal level of impact assessment systems, indicator and monitoring systems, and sustainability reporting systems is discussed in general, followed by a comparison of specific case studies. In Canada, we selected the municipalities of Ottawa, Hamilton-Wentworth and Vancouver and in Flanders, the municipalities of Hasselt, Gent and Leuven. For each case study, we considered the following evaluation criteria: introduction of a long-term vision for a sustainable future; development of goals, targets and indicators; measurement of indicators; involvement and information of the local population; introduction of impact assessment and reporting systems. The discussion section deals with differences in the approach to managing and measuring sustainable development initiatives in Canada and Flanders. This study shows that sustainable development is not yet widely practised at the local level in Canada and Flanders, but Canadian municipalities have more experience with planning processes and vision development, measurement systems and public involvement. The Flemish municipalities were more inclined to go along with international campaigns dealing with local sustainability and take strong sustainable development actions which were not integrated in broader sustainable development policies.  相似文献

The Clean Development Mechanism (CDM) is one of the flexible instruments of the Kyoto Protocol designed to combat climate change so as to bring advantages to developing countries and developed countries alike. Indeed, CDM projects have a two-fold objective: to offset greenhouse gas emissions and to contribute to sustainable development in the host country. However in many cases, the latter objective appears to be marginalized. This is at least partly due to the difficulties surrounding the definition and the measurement of sustainability, in particular in a developing country context. To assess CDM projects’ contribution to sustainable development in the host country, scholars and practitioners need adapted indicator sets. A set of indicators were developed by way of an iterative Delphi approach amongst selected Vietnamese experts. The Delphi approach allowed a systematic collection of the experts’ judgements on the sustainability indicators through a set of sequentially applied questionnaires, interspersed with feedback from earlier responses. This exercise resulted in the selection of a set of 36 indicators, which emphasise economic efficiency, public health and pollution issues. The exercise yielded a locally supported and context-specific set of sustainability indicators that will allow Vietnamese decision-makers to enhance the sustainability of the approved CDM projects. In the future this set should be continually improved through real-life application and further participation from local stakeholders. This study is a first step in a long-term process towards developing an adapted toolkit for sustainability assessment of CDM projects in Vietnam.  相似文献
