Recovery of Household-level assets: Towards a cyclone resilent community
Abstract
Globally Bangladesh is recognized as one of the most vulnerable countries to natural
calamities. Along with cyclones and floods; two most discussed and disastrous hazards of
the country, landslides have caused the death of nearly 235 people in various informal
settlements of Chittagong city and its adjacent urban centers since 1997. In Chittagong
city, about 30 percent of the total population lives in the informal settlements where
living environments are quite unsatisfactory and they are deprived of access to basic
facilities. The rapid growth of urban population of Chittagong city is fuelled by migration
of the rural poor to the city, drawn by perceived chances of finding cash employment in
the industrial sector and pushed by the limited opportunities in rural areas. On arrival,
many are unable to afford proper housing, so turn to live in informal settlements.
Ineffective hill management policy at the national level and weak enforcement by the
local authorities has created space for growing many informal settlements along landslide
prone hill slopes and foothills in Chittagong city. However, there is no institutional
arrangement for vulnerability assessment of those informal settlements to landslides. Few
researches on landslide focus on hill cutting issues but are unable to explain the role of
formal institutional arrangements for reducing vulnerability of the informal settlers.
Neither national level landslide risk reduction organizations nor local level organizations
and NGOs have planned and executed any proper structural and non-structural mitigation
measure other than conventional stabilization (simple retaining walls) of hill toe and
relocation respectively. Besides being more affected by landslides the informal settlers
have less willingness to adapt risk reduction measures like relocation. Mostly land tenure
conflict, trust, socio-economic status (education, income) and powerlessness inhibit these
populations in accepting new institutional arrangements. The growing distrust and
conflict has tightened pre-landslide institutional arrangements for reducing vulnerability.
However, there is usually no standard rule of thumb solution because formulation of
mitigation measure is often unique for each site and requires proper technical evolution of
causative factors. This study explores different strategic design measures on the basis of
assessment of risk, uncertainty, possible consequences, constructability, environmental
impacts and costs. It suggests that, while proposing a specific measure, it is best to keep
simple to match the physical characteristics of the hill and the availability of materials.
The study makes an effort to contribute in the development of a comprehensive design
solution to reduce landslide vulnerability that can be adapted to ensure the settlers
immediate safety.
