The December 2004 Indian Ocean earthquake and tsunamis were an exceptional event. So too was the scale of the response, particularly the level of international funding. Unprecedented donations meant that for once, an international emergency response was largely free of financial constraints. This removal of the funding constraint facilitated observation of the capacity and quality of international disaster aid. The Tsunami Evaluation Coalition conducted five independent thematic assessments in 2005-an impact study was planned, but never implemented. The five evaluations were supported by 44 sub-studies. Based on this work, this paper compares international disaster response objectives, principles and standards with actual performance. It reaches conclusions on four salient aspects: funding; capacity and quality; recovery; and ownership. It ends by proposing a fundamental reorientation of international disaster response approaches that would root them in concepts of sustainable disaster risk reduction and recovery, based on local and national ownership of these processes.  相似文献

建立自然保护区是开展自然保护工作的重要基础。自然保护区的建立首先面临的就是自然保护区的土地权属问题,即自然保护区的土地归谁所有,归谁使用等。本文首先介绍了我国自然保护区土地权属的现状,分析存在的问题,结合我国土地管理的历史背景,指出导致我国自然保护区土地权属不清的原因所在,并分析了土地权属不清所带来不良后果,如自然保护区内资源的过度开发利用、与周边社区纠纷不断等。最后,本文通过借鉴国外自然保护区土地权属管理的经验,结合我国土地权属管理的具体情况,提出解决我国自然保护区土地权属问题的途径。  相似文献

论地质灾害群测群防体系   总被引:7,自引:1,他引:6  
地质灾害群测群防体系是指县、乡、村地方政府组织城镇或农村社区居民为防治地质灾害而自觉建立与实施的工作体制和减灾行动,是一种针对灾害风险进行自我管理的工作体系。实施地质灾害群测群防的根本目的是抓住减灾时机,实现实时高效,具体体现为“六个自我”,即“自我识别、自我监测、自我预报、自我防范、自我应急和自我救治”。本文在理论上界定了地质灾害群测群防体系的定位,可帮助从事具体工作的基层人员更清楚地认识该项工作的实质意义,了解其在国家地质灾害减轻战略中的地位。  相似文献

国家生态工业示范园是中国工业绿色转型的主要载体。本文基于创建国家生态工业示范园为切入点,采用多期双重差分法(difference-in-differences, DID)和2002-2017年上市公司的面板数据,实证考察了国家生态工业示范园对企业绿色创新的影响。研究发现:①创建国家生态工业示范园显著促进了企业绿色创新,平均提升了上市公司绿色发明专利0.883项,绿色实用专利0.465项;②事件分析表明,国家生态工业示范园与企业绿色创新之间存在着“先增后降”的倒“U”形关系;③国家生态工业示范园显著增加了企业环保投资,抑制了企业排污费,但与政府环保补助之间没有必然联系;④国家生态工业示范园更有助于非国有企业、经营状况比较好的企业以及东部经济发达地区的企业绿色创新,并且其绿色创新效应不集中于特定行业(如重污染行业)。本文从微观企业层面为理解创建国家生态工业示范园的经济社会效益提供了启发。  相似文献

Comprehensive biodiversity assessments play an essential role in strengthening global and national conservation strategies. The recently announced first U.S. National Nature Assessment (NNA) provides an unparalleled opportunity to comprehensively review status and trends of biodiversity at all levels. This broad context can help in the coordination of actions to conserve individual species and ecosystems. The scientific assessments that informed the Kunming–Montreal Global Biodiversity Framework adopted at the 2022 Convention on Biological Diversity (CBD) conference of parties provide models for synthesizing information on trends at multiple levels of biodiversity, including decline in abundance and distribution of species, loss of populations and genetic diversity, and degradation and loss of ecosystems and their services. The assessments then relate these trends to data on drivers of biodiversity loss and pathways to their mitigation. The U.S. NNA can augment such global analyses and avoid the pitfalls encountered by previous U.S. efforts by ensuring policy-relevant design, data accessibility, and inclusivity in process and product and by incorporating spatial data relevant to national and subnational audiences. Although the United States is not formally a CBD party, an effective NNA should take full advantage of the global context by including indicators adopted at the 2022 meeting and incorporating an independent review mechanism that supports periodic stocktaking and ratcheting up of ambition in response to identified shortfalls in stemming biodiversity loss. The challenges to design of an effective U.S. assessment are relevant globally as nations develop assessments and reporting to support the new global biodiversity framework's targets. By considering and incorporating the diverse ways in which society values and benefits from nature, such assessments can help bridge the gap between research and conservation practice and communicate the extent of the biodiversity crisis to the public, fostering broad-based support for transformative change in humanity's relationship to the natural world.  相似文献

The successful implementation of the Convention on Biological Diversity's post-2020 Global Biodiversity Framework will rely on effective translation of targets from global to national level and increased engagement across diverse sectors of society. Species conservation targets require policy support measures that can be applied to a diversity of taxonomic groups, that link action targets to outcome goals, and that can be applied to both global and national data sets to account for national context, which the species threat abatement and restoration (STAR) metric does. To test the flexibility of STAR, we applied the metric to vascular plants listed on national red lists of Brazil, Norway, and South Africa. The STAR metric uses data on species’ extinction risk, distributions, and threats, which we obtained from national red lists to quantify the contribution that threat abatement and habitat restoration activities could make to reducing species’ extinction risk. Across all 3 countries, the greatest opportunity for reducing plant species’ extinction risk was from abating threats from agricultural activities, which could reduce species’ extinction risk by 54% in Norway, 36% in South Africa, and 29% in Brazil. Species extinction risk could be reduced by a further 21% in South Africa by abating threats from invasive species and by 21% in Brazil by abating threats from urban expansion. Even with different approaches to red-listing among countries, the STAR metric yielded informative results that identified where the greatest conservation gains could be made for species through threat-abatement and restoration activities. Quantifiably linking local taxonomic coverage and data collection to global processes with STAR would allow national target setting to align with global targets and enable state and nonstate actors to measure and report on their potential contributions to species conservation.  相似文献

Despite an abundance of research reaffirming biodiversity's importance to the health of the planet and society, species continue to go extinct at an alarming rate. Why has continued research on the value of biodiversity not had the intended effect and what can be done about it? We considered biodiversity loss as a public value failure and the result of a misalignment between the logic of inquiry (which guides scientists) and the logic of action (which guides practitioners). We drew lessons from our own research to propose the creation of a national biodiversity strategy designed to link the logic of inquiry with the logic of action and coordinate the production of actionable conservation science and informed conservation action.  相似文献

根据适宜性分析方法,以中山陵园风景名胜区为例,提出了风景名胜区旅游环境适宜性分析的自然状况、环境感应和环境质量3方面8个评价因子,通过网格调查法,从单因子和多因子两方面评价了它的旅游环境适宜性。结果表明,景区内部生态环境优良,尤其是声环境、绿地覆盖率和大气质量,但水环境和垃圾问题不可忽视,同时大部分土地不宜再开发利用,景区外围局部和紫金山登山路径沿线生态环境相对较差。最后针对分析结果,提出通过土地置换、清洁生产、循环旅游等措施改善景区的旅游环境。  相似文献

自然遗产地国家公园模式发展的影响因素与空间扩散   总被引:3,自引:0,他引:3  
以自然生态环境保护与公共游憩为基本目标的国家公园模式被视为一种遗产保护和旅游发展融合互促的成熟模式。文章探讨国家公园模式在全球的空间扩散过程及其驱动因素,研究发现:①公益化价值取向是国家公园模式发展的主要动力;②经济发展水平提高反而会造成国家公园供给空间的缩小;③发展中国家与发达国家存在明显差异,环境关注度和旅游发展水平是发达国家的主要影响因素,而发展中国家的国家公园的发育与环境关注度不相关,与旅游发展水平呈负相关;④国家公园模式呈全球扩散趋势,空间重心的转移受国家宏观政治背景、 生态环境保护等因素的影响。  相似文献
