Discard mitigation - what we can learn from waste minimization practices in other natural resources?     

B. Stockhausen  R.A. Officer  R. Scott 《Marine Policy》2012,36(1):90-95

Solutions to the problem of discarding in fisheries have been debated for decades. Despite this attention, measures to ameliorate discarding have had limited success. Regulators, researchers, and industry continue to struggle with fisheries management and foregone yield in the face of the continued wastage of valuable resources due to discarding.Waste minimization and by-product utilization are powerful imperatives in other sectors that are also reliant on the harvest of natural resources. This paper considers the performance of these sectors in waste minimization and by-product utilization, with the aim of identifying practices and processes that may be applied to ameliorate discarding in fisheries.This paper describes the handling, utilization, and mitigation of discards and waste in the livestock farming, agriculture, mining, and waste management industries, and in particular, in forestry. In terms of biological impact, economic objectives, and management approaches the harvesting of trees has substantial similarities to industrialized fishing. However, the forestry sector has found ways to utilize almost 100% of the natural product harvest by establishing markets and new products. Analogous developments within the fishing industry could substantially improve sustainability through reduced levels of discarding and wastage. Based on the experiences of these sectors it is suggested that evaluations of potential Management Strategies are developed to specifically examine discard mitigation approaches on a broader scale than previously conducted.  相似文献

Framework for the derivation of analytical fragility curves and life cycle cost analysis for non-seismically designed buildings     

《Soil Dynamics and Earthquake Engineering》2015

The quantification of the devastating effects of earthquakes on buildings can be achieved with the use of earthquake risk assessment. The formulation of strategies to minimise this risk is a complex task which relies on data regarding mainly the hazard, vulnerability and remaining life of the building. In this paper, the case study of Limassol municipality is presented. Initially, the building inventory and categorisation is defined followed by the selection of hazard scenarios and the development of analytical vulnerability curves. In the final part, risk assessment is performed leading to the formulation of retrofitting strategies for long term use.  相似文献   

Centrifuge modeling of offshore wind foundations under earthquake loading     

《Soil Dynamics and Earthquake Engineering》2015

The construction of large offshore wind turbines in seismic active regions has great demand on the design of foundations. The occurrence of soil liquefaction under seismic motion will affect the stability of the foundations and consequently the operation of the turbines. In this study, a group of earthquake centrifuge tests was performed on wind turbine models with gravity and monopile foundations, respectively, to exam their seismic response. It was found that the seismic behavior of models was quite different in the dry or saturated conditions. Each type of foundation exhibited distinct response to the earthquake loading, especially in the offshore environment. In the supplementary tests, several remediation methods were evaluated in order to mitigate the relatively large lateral displacement of pile foundation (by fixed-end pile and multi-pile foundation) and excessive settlement of gravity foundation (by densification, stone column, and cementation techniques).  相似文献   

全球碳排放空间约束条件下美国退出《巴黎协定》对中欧日碳排放空间和减排成本的影响     

戴瀚程  张海滨  王文涛 《气候变化研究进展》2017,13(5):428-438

应用全球多部门、多区域动态可计算一般均衡（CGE）模型,采用情景分析方法,评估美国退出《巴黎协定》后,由于其碳排放路径的变化对国际气候谈判中的3个重要谈判方中国、欧盟和日本实现国家自主贡献（NDC）和2℃目标情景下碳排放空间和减排成本的影响。结果表明：在全球碳排放固定且分配方式固定的条件下,美国不同程度的退约将为自身获得较大的碳排放空间,同时挤压其他地区,包括中国、欧盟和日本实现NDC和2℃目标的碳排放空间,将推高中国、欧盟和日本实现NDC和2℃目标的碳价。2030年,2℃目标下中国碳价的升幅将达4.4~14.6美元/t,欧盟为9.7~35.4美元/t,日本为16.0~53.5美元/t。同时将增加中国、欧盟和日本等其他国家和地区的GDP损失。2030年,2℃目标下中国GDP损失的升幅将达220.0亿~711.0亿美元（相当于16.4~53.1美元/人）,欧盟为93.5亿~321.4亿美元（相当于20.7~71.1美元/人）,日本为41.3亿~134.5亿美元（相当于34.3~111.7美元/人）。  相似文献

山洪灾害调查评价是1949年来水利行业最大的非工程措施项目,是规模最大的全国性防灾减灾基础信息普查工程,历时4年,涉及全国30个省305个市2138个防治县（区）,国土面积755万km²,人口近9亿。运用普查、详查、外业测量、分析计算等多种手段,掌握了中国山洪灾害防治区范围、人员分布、下垫面条件、社会经济、历史山洪灾害等基本情况,科学分析了山丘区小流域的暴雨洪水特性,评价了现状防洪能力,计算了预警指标,划定了危险区,为山洪灾害预警预报和应急救援决策提供了基础信息支撑。本文系统介绍了全国山洪灾害调查评价的核心要点,综述了调查评价成果,归纳了调查评价成果要素类型,揭示了全国山洪灾害防治区、人口、历史山洪灾害事件与预警能力的空间分布一致性,即山洪灾害各要素集中分布于青藏高原-四川盆地过渡带、川滇交界地区、黄土高原区、东部沿海地区及华北等地区,最后初步探讨了该成果的应用前景。全国山洪灾害调查评价成果将为中国山洪灾害监测预警预报体系建设及防灾减灾能力提升提供丰富的基础数据支撑。  相似文献   

AIDS mitigation through agriculture‐based interventions in rural contexts: Junior farmer field and life schools and future livelihoods in central Mozambique     

Tanja R. Müller 《Singapore journal of tropical geography》2010,31(3):330-342

This article summarizes findings from a research project on junior farmer field and life schools (JFFLS) as an agriculture‐based intervention to improve the livelihood prospects of children and orphans made vulnerable by HIV/AIDS in central Mozambique. In the sites investigated JFFLS have opened up concrete present and potential livelihood options in agriculture and beyond. More generally, the resource profile dynamics of participants are altered in ways that provide strong grounds to believe that the skills and knowledge they have gained will positively impact the trajectories of their future lives. In terms of HIV/AIDS mitigation, the findings recommend livelihood‐based interventions aimed at altering the vulnerability context of specific population groups.  相似文献   

台湾“莫拉克”台风诱发山地灾害成因与启示   总被引：1，自引：0，他引：1

2009-07"莫拉克"台风在台湾岛内滞留大于40 h,受中央山脉地形以及西南季风的影响,形成"北部风强,南部雨大"的局面.本次降雨为台湾历年之冠,24 h降雨量1 825 mm,48 h雨量2 467 mm,逼近世界降雨极值.全台湾计有31个雨量站过程降雨量超过1 000 mm,23个雨量站超过1 500 mm, 15个雨量站超过2 000 mm,南部部分区域甚至出现6-10日累积降雨量超过其年降雨量情形.最大总雨量位于阿里山,2009-08-06-10累计雨量达2 884 mm.长时间持续强降雨,造成了大量的泥石流、堰塞湖、崩塌、滑坡、山洪等山地灾害.大量的崩塌、滑坡阻塞河道,形成了16处堰塞湖.这些灾害淤埋村镇,毁坏道路、桥梁、堤防、建筑、输电和通讯设施.由于道路交通受损,电力、通讯信号中断,使得许多村庄与外部隔绝,成为孤岛,救援设施与救援物资无法到达灾区,延缓救援进度.受灾较重的乡镇有高雄县甲仙乡、桃源乡、六龟乡、那玛夏乡、杉林乡,南投县鹿谷乡、信义乡、国姓乡,嘉义县阿里山乡、梅山乡、中埔乡,屏东县高树乡、三地门乡、春日乡,台南县南化乡,台东县金峰乡等.截至2009-08,造成全台共619人死亡、肢体74件、76人失踪,其中小林村和新开部落被完全毁灭.台风暴雨、陡峻地形和丰富的松散固体物质等自然因素决定了山地灾害形成的基本因素,高强度长历时的暴雨是直接激发因素,坡地过度开发、道路建设、河道不合理利用等人为因素则加剧了灾情.莫拉克台风暴雨灾害对人们的启示是合理确定开发度,科学利用土地资源; 确保山区溪流行洪空间,把防洪需求作为河谷地开发的限制条件; 注意环境保育,尽量减少工程建设对斜坡的扰动; 提高山地灾害预警标准,建立巨灾监测预警机制;进行灾害风险分析与管理,开展有机结合资源利用与减灾防灾的流域理性开发.  相似文献
