Rendering the world unsafe: 'vulnerability' as western discourse

Disasters seem destined to be major issues of academic enquiry in the new century if for no other reason than that they are inseparably linked to questions of environmental conservation, resource depletion and migration patterns in an increasingly globalised world. Unfortunately, inadequate attention has been directed at considering the historical roots of the discursive framework within which hazard is generally presented, and how that might reflect particular cultural values to do with the way in which certain regions or zones of the world are usually imagined. This paper argues that tropicality, development and vulnerability form part of one and the same essentialising and generalising cultural discourse that denigrates large regions of world as disease-ridden, poverty-stricken and disaster-prone.     

The potential for combining indigenous and western knowledge in reducing vulnerability to environmental hazards in small island developing states

The benefits of indigenous knowledge within disaster risk reduction are gradually being acknowledged and identified. However, despite this acknowledgement there continues to be a gap in reaching the right people with the correct strategies for disaster risk reduction.This paper identifies the need for a specific framework identifying how indigenous and western knowledge may be combined to mitigate against the intrinsic effects of environmental processes and therefore reduce the vulnerability of rural indigenous communities in small island developing states (SIDS) to environmental hazards. This involves a review of the impacts of environmental processes and their intrinsic effects upon rural indigenous communities in SIDS and how indigenous knowledge has contributed to their coping capacity. The paper concludes that the vulnerability of indigenous communities in SIDS to environmental hazards can only be addressed through the utilisation of both indigenous and Western knowledge in a culturally compatible and sustainable manner.     

湘中地区恩口煤矿老采区复采的水害防治研究

湘中地区碳酸盐岩广泛分布,其中岩溶的发育受岩性、地貌、水文、构造运动等诸多因素的控制,主要分布在地下水排泄区,给煤炭资源的开发带来了严重水患。针对恩口煤矿水害问题,笔者在翔实的野外调查基础上,通过分析矿区水文地质条件、矿井水文地质特征;总结以往矿山防治水经验和教训;探讨今后老采区复采的防治水害方向和重点;认为壶天河的山口冲段、小碧河的西坪段、涟水河的杨家冲段等为重点防区,对河床铺底强度不可靠的部位应该重新加强铺底。

Newspaper response to flood and erosion hazards on the North Lake Erie shore

The study is primarily concerned with newspaper responses to flooding and erosion associated with Great Lakes high water in 1952–1953 and 1972–1974. Underlying the research is a general interest in informing the public more widely on choices available in resource and environmental decision making.     

陕西关中渭北地区村镇建筑防火现状调查与分析

根据相关统计，农村地区建筑面临与城市地区同样的火灾风险。为了农村地区人民生命财产安全，预防火灾，从村镇规划及布局、消防设施及人员消防意识、户舍基本情况调查入手，对陕西关中渭北地区村镇建筑防火现状进行调查与分析。根据调查结果，发现该地区村镇建筑防火条件薄弱，与相关规范差距很大，人员消防意识淡薄，缺乏相关立法规范村镇消防责任制，相关防火规范不完善，应该引起各方对农村防火的高度重视。     

Health risks of residential wood heat

The resurgence in the use of wood in the United States for residential heating has been accompanied by a dramatic increase in deaths and injuries from residential fires. Toxic materials present in woodsmoke also appear to present a significant public health hazard. As a result of these factors, production of residential wood heat can be up to two orders of magnitude more hazardous than generation of an equivalent amount of electric energy at a coal-fired power plant. Proper care in installation and operation of wood stoves, as well as technological innovations that control wood-stove emissions, can greatly reduce the health and safety hazards of residential heating with wood.     

Mapping social vulnerability to natural hazards in Italy: A suitable tool for risk mitigation strategies

Italy is one of the European countries that are most heavily exposed to a wide range of natural hazards, which might cause large economic losses. In this context, the assessment of social vulnerability has an important role for evaluating the capacity of a community to prepare for, respond to and recover from disasters. However there are currently no published studies analysing social vulnerability and its spatial distribution in Italy. Within this framework, this paper aims to apply a proven method for assessing social vulnerability at the national scale, while considering the contribution of the socioeconomic and demographic factors that affect the Italian population. The proposed methodology is based on the Hazard-of-Place Model approach, and uses free and open source software applications (FOSS). Specifically, we selected significant components through Principal Component Analysis and derived their spatial distribution. Using component scores, we derived a social vulnerability index, evaluated its geographic distribution, and performed a cluster analysis on its spatial variation. The analysis identified different spatial patterns across Italy, providing useful information for identifying the communities most likely to experience negative natural disaster impacts due to their socioeconomic and demographic characteristics. This research represents an important contribution to improve the potentiality of risk mitigation strategies and in designing risk custom-made policies.
