Communicating risk for vulnerable groups: a case study of the Mano community’s strategies for collective knowledge to action

This paper discusses the emergent interest in risk communication as a strategy for disaster risk reduction. Communication plays an essential role in understanding risk, but studies suggest that people often do not respond in the way that risk experts anticipate. For risk communication to be effective, vulnerable communities need to understand risk within the local context as well as in terms of sustainability. Risk messages offer communities a way to enhance their collective knowledge of existing vulnerabilities, leading them towards alternative solutions for action. A longitudinal study of the Mano community development approach and its recovery from the 1995 Kobe earthquake illustrates how risk communication dynamics contributed to the community’s sustainable risk reduction. The study concludes that risk communication is a collaborative way for a community to work with risk experts, own their risk information, influence existing policies and practices, develop solutions to reduce vulnerability, and ultimately enhance a community’s capacity for managing future risk.

Ecosystem engineering potential of the gastropod Terebralia palustris (Linnaeus, 1767) in mangrove wastewater wetlands - A controlled mesocosm experiment

The effect of different sewage concentrations (0, 20, 60 and 100%), vegetation (Bare, Avicennia marina or Rhizophora mucronata) and immersion periods (immersion/emersion period of 12/12 h or 3/3 days just for 100%) conditions were studied for 6 months on survival and growth rates of Terebralia palustris (Linnaeus, 1767). Gastropods' activity and ecosystem engineering preformed at bare and A. marina planted cells and 3 sewage conditions (0, 20 and 60%) were determined. Survival rates were higher than 70% in all treatments. Growth rate decreased significantly with increasing sewage concentrations (mainly at unplanted conditions) and longer immersion periods. A complete shift (from immersion to emersion periods) and a significant decrease in mobility and consequently its engineer potential, due to sewage contamination, lead to a 3-4 fold decrease in the amount of sediment disturbed. Sewage contamination, primary producers' abundance and environmental conditions may have influenced the gastropods survival, growth and its ecosystem engineering potential.     

滨州市沿海防潮工程的生态响应

地处黄河三角洲腹地的滨州沿海为风暴潮多发区,沿海防潮工程建设已取得了显著的经济社会效益,同时也带来了一些负面生态效应,主要表现在:海岸侵蚀、潮滩潮沟退化、贝壳堤岛部分丧失、鱼类回游通道截断和入海河流水质恶化等。建议今后应加强防潮工程生态影响监测与评价,海岸带生态修复和防潮工程技术研究,以充分发挥沿海防潮工程的作用。     

Managing the Three-Rivers Headwater Region, China: From Ecological Engineering to Social Engineering

The three-rivers headwater region (THRHR) of Qinghai province, China plays a key role as source of fresh water and ecosystem services for central and eastern China. Global warming and human activities in the THRHR have threatened the ecosystem since the 1980s. Therefore, the Chinese government has included managing of the THRHR in the national strategy since 2003. The State Integrated Test and Demonstration Region of the THRHR highlights the connection with social engineering (focus on improving people’s livelihood and well-being) in managing nature reserves. Based on this program, this perspective attempts a holistic analysis of the strategic role of the THRHR, requirements for change, indices of change, and approaches to change. Long-term success of managing nature reserves requires effective combination of ecological conservation, economic development, and social progress. Thus, the philosophy of social engineering should be employed as a strategy to manage the THRHR.     

G2京津塘高速公路万辆车流的交通事故灾害与气象综合指数的关系

通过整理G2京津塘高速公路3年(2007年3月至2010年2月)逐日逐时万辆车流的交通事故灾害和交通流量及气象要素资料,并将万辆车流的交通事故灾害(交通事故灾害与交通流量之商)与同步气象综合指数进行日变化相关分析;结果表明:平均万辆车流的交通事故灾害的日变化最高峰出现在05时,年平均高峰值高达2.34起·辆-1·10-4;年度、春季、夏季、秋季和冬季的平均万辆车流的交通事故灾害与同步气象综合指数均呈正抛物线的偏右侧相关,即万辆车流的交通事故灾害随气象综合指数的加大而增多;统计学检验(R＞Rα=0.01和F＞Fa=0.01)效果很好.四个季节的万辆车流的交通事故灾害与气象综合指数相关的系数高达0.7781～0.8537.为了更好地将自动气象监测信息服务于高速公路交通安全,在分析成果的基础上设计出了高速公路万辆车流的交通事故灾害的气象综合指数风险等级指标,以期为高速公路交通安全提供客观的科学依据.
