Since 2000, landslides in southeast Bangladesh have resulted in over 700 deaths, most of which were in informal settlements. For instance, the 2007 landslides in informal settlements in Chittagong and the 2017 landslides in Rangamati took 127 and 150 lives, respectively. Although the government of Bangladesh claims to implement risk reduction, the number of deaths associated with landslides is increasing. Hence, this study investigated the ways to enhance landslide risk reduction interventions by addressing several scientific and technical issues related to disaster risk reduction. This study conducted focus group discussions, key informant interviews and expert interviews with key stakeholders in landslide risk management to collect qualitative data. Moreover, the historical accounts of settlements, media reporting, institutional action plans and policies were reviewed.
By integrating primary and secondary data, this study found that several political-economic aspects are major anthropogenic contributors to the recent increase in landslides in the region. The contributing factors included the following: policy and action plans to raise regional population; land management; illegal deforestation; plans to establish hydroelectricity in hilly areas; ownership of settlements; manipulation of water, gas and electricity supply to illegal settlements; commercial plantations; lack of risk governance; unplanned development activities; natural population rise; increased settlement along hill slopes. This study identified and discussed lessons learned from previous landslide disasters, the weakness of early warning systems and their dissemination and ways to improve evacuation, rescue, relief and risk reduction. Finally, this study formulated recommendations for the effective implementation of landslide risk reduction in southeast Bangladesh.
自2000年以来,孟加拉国东南部的山体滑坡已导致700多人死亡,其中大部分发生在非正式定居点。例如,2007年吉大港非正式定居点的山体滑坡和2017年朗加马蒂的山体滑坡分别造成127人和150人死亡。尽管孟加拉国政府声称在实施风险降低措施,但与山体滑坡相关的死亡人数仍在增加。因此,本研究通过解决与灾害风险降低相关的若干科学和技术问题,调查了加强山体滑坡风险降低干预措施的方法。本研究与山体滑坡风险管理的主要利益相关者进行了焦点小组讨论、关键信息提供者访谈和专家访谈,以收集定性数据。此外,还审查了定居点的历史记录、媒体报道、机构行动计划和政策。
通过整合一手和二手数据,本研究发现,若干政治经济方面是该地区近期山体滑坡增加的主要人为因素。促成因素包括:增加区域人口的政策和行动计划;土地管理;非法砍伐森林;在山区建设水电的计划;定居点的所有权;向非法定居点供应水、气和电的操控行为;商业种植园;缺乏风险治理;无计划的发展活动;自然人口增长;山坡沿线定居点增加。本研究确定并讨论了从以往山体滑坡灾害中吸取的教训、预警系统的弱点及其传播情况,以及改善疏散、救援、救济和风险降低的方法。最后,本研究为在孟加拉国东南部有效实施山体滑坡风险降低制定了建议。
