9·11事件以后,在美国政府的主要倡议和推动下,作为一个受到恐怖主义威胁的高风险行业,国际海运业为保障人员、船舶、货物以及国际贸易体系的安全做出了不懈努力。国际海事组织和有关国家政府采取了诸如“海关-贸易伙伴反恐”(C-TPAT)、“集装箱安全倡议”(CSI)、“修订SOLAS公约修正案和制定保安(ISPS)规则”等一系列重要措施。其中影响最大的就是修订SOLAS公约修正案和制定ISPS规则。而这一系列法律文件的通过,使海上反恐行动有了一个较完整的法律体系,对于保障船舶、船员、旅客和港口设施的安全,防止和抵御恐怖主义对海运业的攻击,维持国际航运、国际贸易的正常运行,乃至整个国际社会的安全都有重要意义。中国海运界一直积极支持国际海运界的海上反恐行动,紧密结合港口国检查,积极推动和实施了SOLAS公约和ISPS规则等一系列新的法律文件。当然,包括中国海运界在内的国际海运界在实施新的海上保安规则时,会遇到一些新的问题。如何妥善解决这些问题,以更好地推进履约和港口国检查,以此提高海运界的保安及管理水平,成为此次论坛所要探讨的中心议题。 相似文献

We explore how marine ecosystem–based management (EBM) is translated from theory to practice at six sites with varying ecological and institutional contexts. Based on these case studies, we report on the goals, strategies, and outcomes of each project and what we can learn from these efforts to guide future implementation and assessment. In particular, we focus on how projects dealt with the challenges of working across geographic scales and diverse governance arrangements. While we hypothesized that EBM in the United States would be distinct from EBM in developing countries due to differences in social and political factors, we found that sites faced similar challenges. Variation among sites appeared to be more closely related to the preexisting management context and the scale at which the projects began rather than to clear differences between the United States and developing country contexts. EBM project implementers were able to overcome many of these challenges by focusing on a limited number of specific objectives, starting at a small scale, pursuing adaptive management, and monitoring a diverse set of indicators. These findings are directly relevant to current and future EBM efforts in these and other places. 相似文献

While scores of millions of dollars have been invested in coastal research, the proportion spent assessing the effectiveness of alternative management tools and analyzing how program attributes and contextual factors shape program outcomes is relatively small. Like other professionals, ICM practitioners are constantly seeking to "make sense" of what is happening in their program design and implementation activities as well as solve specific problems. Such learning involves gathering information about experience, processing this information to generate knowledge, and then applying that knowledge to create changes in organizational structures or practices. This article identifies some of the formal and informal "inquiry strategies" by means of which ICM intellectual capital can be expanded and lessons can be identified. The first section briefly focuses on the types of uncertainties and knowledge gaps around which learning activities need to be organized. The second and primary section reviews some of the formal "sense-making" and inquiry activities for harvesting ICM experience and creating lessons. The third section identifies some of the ways the knowledge gleaned from these inquiry strategies gets expressed. 相似文献
