Assessing differences in chemical disaster proneness: The community chemical hazard vulnerability inventory*

The burgeoning number of accidents with dangerous chemicals makes it incumbent upon community and regional planners to systematically deal with this problem. The first step invariably involves the assessment of the likelihood and type of incident which may impact a given area so that disasters may be averted or, at least, their effects mitigated. This paper presents one such assessment scheme, the Community Chemical Hazard Vulnerability Inventory (CCHVI). This instrument, aside from considering the type and volume of substances posing a threat to a designated area, considers the physical and human resources available, as well as the general state of readiness of the area (including such things as the interface of emergency-related organizations). The use of such vulnerability assessment instruments allows local emergency planners to identify particular dangers within their communities and permits regional planners to allocate funds for planning according to relative needs.     

Housing reconstruction after two major earthquakes: the 1994 Northridge earthquake in the United States and the 1999 Chi-Chi earthquake in Taiwan

The idea of pre-impact recovery planning has recently been promoted by researchers and practitioners, but very little research has been done to evaluate its effects on disaster recovery. This study compared two jurisdictions — the city of Los Angeles, California and Taichung county in Taiwan — in their recovery from earthquakes. Although the two cases also differ with respect to variables other than the presence of pre-impact recovery plans, the available data suggest that having a pre-impact recovery plan facilitates housing reconstruction and allows local officials to make more effective use of the window of opportunity after disaster to integrate hazard mitigation into the recovery process.     

Effects of a tropical cyclone on the drinking-water quality of a remote Pacific island

The effect of a cyclone (Ami, January 2003) on drinking-water quality on the island of Vanua Levu, Fiji was investigated. Following the cyclone nearly three-quarters of the samples analysed did not conform to World Health Organisation (WHO) guideline values for safe drinking-water in terms of chlorine residual, total and faecal coliforms, and turbidity. Turbidity and total coliform levels significantly increased (up 56 and 62 per cent, respectively) from pre-cyclone levels, which was likely due to the large amounts of silt and debris entering water-supply sources during the cyclone. The utility found it difficult to maintain a reliable supply of treated water in the aftermath of the disaster. Communities were unaware they were drinking water that had not been adequately treated. Circumstances permitted this cyclone to be used as a case study to assess whether a simple paper-strip water-quality test (the hydrogen sulphide, H(2)S) kit could be distributed and used for community-based monitoring following such a disaster event to better protect public health. The H(2)S test results correlated well with faecal and total coliform results as found in previous studies. A small percentage of samples (about 10 per cent) tested positive for faecal and total coliforms but did not test positive in the H(2)S test. It was concluded that the H(2)S test would be well suited to wider use, especially in the absence of water-quality monitoring capabilities for outer island groups as it is inexpensive and easy to use, thus enabling communities and community health workers with minimal training to test their own water supplies without outside assistance. The importance of public education before and after natural disasters is also discussed.     

"We all knew that a cyclone was coming": disaster preparedness and the cyclone of 1999 in Orissa, India

Imagine that a cyclone is coming, but that those living in the affected areas do nothing or too little to protect themselves. This is precisely what happened in the coastal state of Orissa, India. Individuals and communities living in regions where natural hazards are a part of daily life develop strategies to cope with and adapt to the impacts of extreme events. In October 1999, a cyclone killed 10,000 people according to government statistics, however, the unofficial death toll is much higher. This article examines why such a large loss of life occurred and looks at measures taken since then to initiate comprehensive disaster-preparedness programmes and to construct more cyclone shelters. The role of both governmental organisations and NGOs in this is critically analysed. The good news is that, based on an assessment of disaster preparedness during a small cyclone in November 2002, it can be seen that at community-level awareness was high and that many of the lessons learnt in 1999 were put into practice. Less positive, however, is the finding that at the state level collaboration continues to be problematic.     

2002年6月陕西佛坪山洪灾害成因及特征

陕西省佛坪县位于秦岭中部南坡。2002年6月9日,该县山洪暴发,造成数百人死亡和失踪及巨大财产损失。15小时250.3mm的特大暴雨,是本次洪灾形成的根本原因。防灾意识不强,在山洪危险区建房等人为因素增大了洪灾损失。由于县境内主河支流短小,洪峰快速形成,具有很大破坏性。针对洪灾的成因和特征,提出了洪灾对策。

Disaster mitigation and preparedness on the Nicaraguan post-Mitch agenda

Nicaragua provides an example of how a major disaster, in this case Hurricane Mitch, can transform the national agenda for disaster mitigation and preparedness. Hurricane Mitch was a reminder of how extremely disaster prone Nicaragua is, and also how neoliberal reforms have weakened governmental response capacity. In the face of critiques of how governmental policies had affected preparedness and response, discussions of this transformation became a highly politicised process where the debate over alternative development models tended to overshadow the original calls to strengthen risk management. Progress can be seen in some areas, such as disaster mitigation through environmental management. This study of NGO roles, and their relations with other key actors, draws attention to the need to anchor improved risk management in local-level NGO-government collaboration. Structures are being put into place to achieve this aim, but dependence on donor financing raises questions regarding the longer-term sustainability of these efforts.     

Disaster mitigation and preparedness: the case of NGOs in the Philippines

The Philippines is very vulnerable to natural disasters because of its natural setting, as well as its socio-economic, political and environmental context--especially its widespread poverty. The Philippines has a well-established institutional and legal framework for disaster management, including built-in mechanisms for participation of the people and NGOs in decision-making and programme implementation. The nature and extent of collaboration with government in disaster preparedness and mitigation issues varies greatly according to their roots, either in past confrontation and political struggles or traditional charity activities. The growing NGO involvement in disaster management has been influenced by this history. Some agencies work well with local government and there is an increasing trend for collaborative work in disaster mitigation and preparedness. Some NGOs, however, retain critical positions. These organisations tend to engage more in advocacy and legal support for communities facing increased risk because of development projects and environmental destruction. Entry points into disaster mitigation and preparedness vary as well. Development-oriented agencies are drawn into these issues when the community members with whom they work face disaster. Relief organisations, too, realise the need for community mobilisation, and are thus drawn towards development roles.
