Environmental implications for disaster preparedness: lessons learnt from the Indian Ocean Tsunami

The impact of disasters, whether natural or man-made, not only has human dimensions, but environmental ones as well. Environmental conditions may exacerbate the impact of a disaster, and vice versa, disasters tend to have an impact on the environment. Deforestation, forest management practices, or agriculture systems can worsen the negative environmental impacts of a storm or typhoon, leading to landslides, flooding, silting, and ground/surface water contamination. We have only now come to understand these cyclical causes and impacts and realize that taking care of our natural resources and managing them wisely not only assures that future generations will be able to live in sustainable ways, but also reduces the risks that natural and man-made hazards pose to people living today. Emphasizing and reinforcing the centrality of environmental concerns in disaster management has become a critical priority, requiring the sound management of natural resources as a tool to prevent disasters and lessen their impacts on people, their homes, and livelihoods. As the horrors of the Asian tsunami of December 2004 continue to be evaluated, and people in the region slowly attempt to build a semblance of normalcy, we have to look to the lessons learnt from the tsunami disaster as an opportunity to prepare ourselves better for future disasters. This article focuses on findings and lessons learnt on the environmental aspects of the tsunami, and its implications on disaster preparedness plans. This article essentially emphasizes the cyclical interrelations between environments and disasters, by studying the findings and assessments of the recent Indian Ocean earthquake and tsunami that struck on 26 December 2004. It specifically looks at four key affected countries - Maldives, Sri Lanka, Indonesia, and Thailand.     

Global climate change and the politics of disaster

The paper explores the potential political impact of global climate change and, more generally, of natural disaster. Because the affluent West has largely tamed the natural and the social domains, popular clamor for government to anticipate, prevent, and redress disaster increases. I delineate several consequences of the new politics of disaster.     

城镇化建设中的减灾思考

十六大以来，我国迎来了全面推进城镇化建设的一个黄金时期，在小城镇建设当中要以“以人为本”的理念为指导，走科学规划、合理布局的道路。这就必然要将减灾概念融入城镇建设当中，对可能发生的地震等灾害进行设防，建设充满人文关怀的小城镇．本文对小城镇的减灾工作的若干问题进行了探讨.     

Experimental study on the influence mechanism of gas seepage on coal and gas outburst disaster

By using the self-developed triaxial servo-controlled seepage equipment for thermo-fluid-solid coupling of coal containing gas and the self-developed coal and gas outburst simulation test device, experiments to study the influence mechanism of gas seepage on coal and gas outburst disasters. The results show that: (i) gas seepage decreases the strength of coal containing gas and accelerates its failure process; (ii) under the same gas pressure, the confining pressure is larger, the more difficult the gas flows and the greater the intensity of coal containing gas is; (iii) in the process of coal and gas outburst, the greater the vertical ground stress is, the more powerful the outburst will be; (iv) the influence mechanism of gas seepage on coal and gas outburst disasters is as follows: firstly, gas seepage weakens the mechanical properties of coal body, which makes it much easier for coal and gas outburst to occur; secondly, on the same effect of external force, it will be easy to form a high gas pressure zone in the coal body under the difficult condition of gas seepage, and accumulate more gas compression energy, which is the energy source for coal and gas outburst, and it is also the main dynamic source to throw and grind the coal.     

环境污染事故灾害的特点与影响分析

环境污染事故灾害现已成为环境灾害中不可忽视的灾种之一，严重威胁着人们生命与财产的安全，并制约着环境经济社会的持续稳定发展。本文根据山东省近几年环境污染事故灾害的状况，系统分析了其特点与环境影响，并提出了相应的防减灾对策。

新疆绿洲的沙漠化灾害及减灾措施

风沙灾害频发的季节是每年3～6月份。流动沙漠与绿洲直接毗邻的格局增加了下风方向绿洲风沙危害的态势。风沙灾害严重区有莫索湾绿洲,精河,艾比湖地区绿洲,喀什地区绿洲,和田地区绿洲,塔里木河下游绿洲。 新疆绿洲风沙灾害的发展趋势:绿洲外围及河流下游沙漠化土地在继续发展,风沙、尘埃天气显著增加;灌溉绿洲腹地特别是连片的大型绿洲风沙灾害显著减轻,6级以下起沙风基本上不造成风沙灾害;对于突发性,风速达8～9级以上的黑风尘暴,灾害仍不可避免。 采取的减灾措施:针对新疆许多河流下游断流,荒漠生态环境严重退化,沙漠化土地日益扩展蔓延的严峻局面,新疆已经着手进行主要河流的流域规划。塔里木河应急输水工程业已进入实施阶段;减轻对荒漠植被的压力,达到保护绿洲外荒漠植被的目的;加强大型防护林和农田防护林的建设;建立绿洲防止土地沙漠化、减轻风沙灾害的示范区和样板。新疆绿洲风沙灾害的根治仍然是任重道远。
