生态文明建设是全面建成小康社会宏伟目标的重要组成部分,全面建成小康社会宏伟目标的提出对生态文明建设提出了更高的要求,但我国的生态文明建设面临的形势不容乐观,生态环境恶化、资源严重短缺、矛盾交织叠加已成为我国建设生态文明的严重障碍,严重影响到全面建成小康社会目标的实现。因此,必须要从牢固树立生态文明理念、加快转变经济增长方式、加强污染防治和生态修复、建立健全生态法律制度体系、健全建设生态文明的体制机制人手,以加快建设生态文明来引领全面建成小康社会。  相似文献

Rural West Africans confront a challenging array of circumstances in pursuit of their livelihoods, which are negotiated through repertoires of knowledge, skill, wisdom and information that are held individually, communally or as the prerogative of experts. Of some significance is timing: finding the most effective or propitious moment for action. On the farm, anticipating the beginning and progress of the rains is crucial and sought through the empirical observation of natural phenomena, or as in northwest Nigeria additionally through agricultural star calendars and almanacs by Muslim clerics. Furthermore, some clerics use divination to identify propitious moments for their clients whereby they may achieve success in non-farm jobs and businesses that are an integral part of rural livelihoods. Taking action to achieve particular outcomes on and off the farm raises issues about local people's understanding of the physical world and their place within it, and the power of religion and the supernatural. An appreciation of such matters would appear to be crucial for those from the scientific and technological North who may be attempting to transform African societies.  相似文献

The emerging field of risk communication has yet to thoroughly grapple with how the mass media report risk. Through a content analysis of five newspapers noted for their science reporting, newspaper coverage of four environmental hazards is compared to media coverage of more traditional risky events. In general, these slow‐to‐develop stories are reported in much the same way as more traditional disaster stories. News accounts emphasized an event orientation, framed risks in terms of human activity rather than social and political contexts, described risk in terms of harms and benefits, and relied on traditional sources. The authors then explore how this version of mass‐mediated risk might change current definitions of risk communication and how a mediated construction of risk may influence public perception of the political choices these issues raise.  相似文献

Forensic arthropod succession patterns are known to vary between regions. However, the northern habitats of the globe have been largely left unstudied. Three pig carcasses were studied outdoors in Whitehorse, Yukon Territory. Adult and immature insects were collected for identification and comparison. The dominant Diptera and Coleoptera species at all carcasses were Protophormia terraneovae (R‐D) (Fam: Calliphoridae) and Thanatophilus lapponicus (Herbst) (Fam: Silphidae), respectively. Rate of decomposition, patterns of Diptera and Coleoptera succession, and species dominance were shown to differ from previous studies in temperate regions, particularly as P. terraenovae showed complete dominance among blowfly species. Rate of decomposition through the first four stages was generally slow, and the last stage of decomposition was not observed at any carcass due to time constraints. It is concluded that biogeoclimatic range has a significant effect on insect presence and rate of decomposition, making it an important factor to consider when calculating a postmortem interval.  相似文献

This paper seeks to identify major shifts in the Australian environmental policy agenda over the past fifty years, and discusses the possible causes of and variables affecting agenda change. The issue of what comprises ‘environment’ policy is discussed, with reference to overlaps and intersections with other policy sectors such as agriculture, public health, energy and regional affairs. While the diversity of the environment policy domain complicates any analysis of trends, there have been two persistent trends of (i) an expansion from a more narrowly to a more broadly defined suite of issue (from environment to sustainable development) and incorporation of environment into natural resource management, and (ii) an increasing diversity of policy instruments being used. Consistent with the wide variety of issues confronted, pragmatism and convenience are often as influential as political ideology or underlying trajectories. The drivers of policy change are diverse, including biophysical factors such as drought, political leaders and international policy developments, and punctuations are often better interpreted as intensification or redirections of past policy trajectories.  相似文献

Abstract

The article addresses issues of ideological horizons in relation to the information superhighway, as they affect environmental communication, with a special focus on grassroots communities at fish-landing sites along Lake Victoria, in Uganda. While in the ‘button society’ a great deal of information is accessible at the push of a button, the most that button-less grassroots societies have to contend with, is a simple radio switch. Given this continuum of ideological horizons, both communities cannot interpret environmental management concerns in the same way. Conceptually, the article is guided by Hall's encoding and decoding framework, whereby due to a failure to share ‘meaning’ (between the two parties) miscommunication arises. The discussion is based on findings of a survey for a research project that sought to find behavioural change communication strategies that can be used to empower grassroots communities to participate more in managing their local environment in a sustainable way. The research looked at the communication of environmental issues pertaining to solid waste management and sanitation. The major question of interest to the discussion is why there is continued environmental degradation at Lake Victoria fish-landing sites, despite the available environmental information and existing frameworks for ensuring proper environmental management.  相似文献

This study addresses the dynamics of the issue space in multiparty systems by examining to what extent, and under what conditions, parties respond to the issue ownership of other parties on the green issue. To understand why some issues become part and parcel of the political agenda in multiparty systems, it is crucial not only to examine the strategies of issue entrepreneurs, but also the responses of other parties. It is argued that the extent to which other parties respond to, rather than ignore, the issue mobilisation of green parties depends on two factors: how much of an electoral threat the green party poses to a specific party; and the extent to which the political and economic context makes the green issue a potential vote winner. To analyse the evolution of the green issue, a time‐series cross‐section analysis is conducted using data from the Comparative Manifestos Project for 19 West European countries from 1980–2010. The findings have important implications for understanding issue evolution in multiparty systems and how and why the dynamics of party competition on the green issue vary across time and space.  相似文献

环境税收法律制度以外部性理论、公共物(产)品理论和可持续发展理论为理论支撑;发达国家通过开征多种环境税、对原有税种进行有利于环境保护的调整等约束性的环境税收措施和通过对环保产品、环保技术、环保投资以及环保行为等方面进行税收优惠的激励性的环境税收措施,不仅有效地利用和保护了资源和环境,还为完善环境税收法律制度提供了如下经验与启示:进行环境税收立法,开征环境税要循序渐进,逐步实施;设计适合本国国情的具有可操作性的环境税收法律制度;多种环境保护手段协调配合,建立混合制度;在绿化现有税收的同时开征多种环境保护税;中央和地方的环境税收征管权限应清晰明确;税款应专款专用;税务部门应与其他部门进行合作;履行国际义务等。  相似文献
