Policy planning in the Oosterschelde estuary 总被引:2,自引:2,他引:0
During the execution of the Delta project the awareness of the environmental values of estuaries was growing strongly. This awareness has led to a reconsideration of the original proposal to close off the Oosterschelde, and to an alternative view of the management of the estuarine areas and of the civil engineering structures. Now, the completed storm-surge barrier and two compartmentation dams, together with the reinforced dikes, guarantee a sufficient safety against flooding.After the decision to build a storm-surge barrier it was soon recognized that a coherent plan would be needed for the management and development of the Oosterschelde. A policy plan was accordingly produced in which the broad outlines of the policy were set out regarding the various potential uses of the estuary and the possible means of effecting them. Because of the periodic improvement and adjustment of the policy plan an environmental research programme was set up. Also, environmental research played a significant role in the decision-making processes for the completion of the barrier and the compartmentation dams as well as for the management of the storm-surge barrier.The coping-stone of the Delta Project marks the beginning of a new period in the water management of the Netherlands: the period of integrated water management. 相似文献

High-quality biodiversity monitoring is crucial in the era of rapid global biodiversity loss and for the evaluation of conservation outcomes at different spatial scales. Biodiversity offsets are conservation actions that aim to an outcome of no net loss of biodiversity by compensating for the negative impacts from development projects. Successful use of offsets requires that the biodiversity gains and losses between offset and development areas are adequately and comparably measured. Numerous local-level biodiversity surveys are conducted to estimate the biodiversity values of potential development areas in Finland every year. These surveys are done for local planning purposes, and their results are almost never published. We studied Finnish biodiversity surveys to assess their adequacy with regards to biodiversity offsetting. Our data included all biodiversity surveys (n = 206) documented in the region of Southwest Finland during the time period of 1997–2014. We analysed the surveys based on Finnish nature legislation and biodiversity related criteria gathered from other offset and conservation programs. We found the surveys to be inadequate in their assessment of nature values and spatial considerations for offset purposes. We used cluster analysis to study the differences between surveys based on the inventoried nature values and found surveys were clustered into 3 different groups. The characteristics of surveys also varied between individual surveyors. Our results show that the current execution of biodiversity surveys is not compatible enough with the quality of surveys needed for biodiversity offsets. Surveys must be standardized to ensure their comparability and sufficient measurement of biodiversity with ecologically and geographically important features. 相似文献

Some theorists argue that moral bioenhancement ought to be compulsory. I take this argument one step further, arguing that if moral bioenhancement ought to be compulsory, then its administration ought to be covert rather than overt. This is to say that it is morally preferable for compulsory moral bioenhancement to be administered without the recipients knowing that they are receiving the enhancement. My argument for this is that if moral bioenhancement ought to be compulsory, then its administration is a matter of public health, and for this reason should be governed by public health ethics. I argue that the covert administration of a compulsory moral bioenhancement program better conforms to public health ethics than does an overt compulsory program. In particular, a covert compulsory program promotes values such as liberty, utility, equality, and autonomy better than an overt program does. Thus, a covert compulsory moral bioenhancement program is morally preferable to an overt moral bioenhancement program. 相似文献

Confusing means with ends: A manager's reflections on experience in agricultural landscapes of Western Australia 总被引:1,自引:0,他引:1
Ken J. Wallace 《Ecological Management & Restoration》2003,4(1):23-28
Summary Since 'landcare' in its modern form began in Australia during the early 1980s, considerable resources have been focused on applying tools and processes, such as community empowerment, regionalization, integrated catchment management, and facilitation and coordination. While these are valuable tools to achieve goals, they are not themselves goals. Unfortunately, they have frequently become ends in themselves. This confusion of means and ends has hindered landcare achievements in Australia. Examples of this are provided, and then contrasted with management based on goals that emphasize realistic targets, highlight barriers to goal achievement, and facilitate the development of well-targeted actions. The complexity of most natural resource management issues, the lack of technical solutions and the long timescales over which management must be applied have all contributed to the confusion of means and ends. 相似文献

Respecting Autonomy Over Time: Policy and Empirical Evidence on Re‐Consent in Longitudinal Biomedical Research 下载免费PDF全文
Susan E Wallace Elli G Gourna Graeme Laurie Osama Shoush Jessica Wright 《Bioethics》2016,30(3):210-217
Re‐consent in research, the asking for a new consent if there is a change in protocol or to confirm the expectations of participants in case of change, is an under‐explored issue. There is little clarity as to what changes should trigger re‐consent and what impact a re‐consent exercise has on participants and the research project. This article examines applicable policy statements and literature for the prevailing arguments for and against re‐consent in relation to longitudinal cohort studies, tissue banks and biobanks. Examples of re‐consent exercises are presented, triggers and non‐triggers for re‐consent discussed and the conflicting attitudes of commentators, participants and researchers highlighted. We acknowledge current practice and argue for a greater emphasis on ‘responsive autonomy,’ that goes beyond a one‐time consent and encourages greater communication between the parties involved. A balance is needed between respecting participants' wishes on how they want their data and samples used and enabling effective research to proceed. 相似文献

AbstractPerceptions of the populace play a central and decisive role in advancing pro-environmental policies. To study attitudes and perceptions towards environmental measures, we apply several items of New Ecological Paradigm (NEP) and Value-Belief-Norm (VBN) theories to cross-examine the public perceptions of climate change in the urban city-state of Singapore through analysis of quantitative questionnaires and qualitative semi-structured interviews. The perceptions were explored about ecological orientation (two dimensions of NEP: level of concern, self-reported knowledge) and environmental behavior (two dimensions of VBN: acceptance and support of national adaptation measures, confidence in adaptation). There is a moderate to high concern for climate change, in general, and sea level rise and flooding, in particular, and the concern is expected to increase in the future. Individuals who indicated a higher level of concern are likely to be more accepting and supportive of climate change measures. Also, while the majority of the populace are amenable to legislative measures from the government, such as enacting pro-environmental laws and more are agreeable to accepting cuts on living standards, as opposed to paying more in prices and taxes. Ecological orientation does not translate directly into environmental behavior, highlighting the gulf between perception and behavior in Singapore. 相似文献
