Disaster preparedness for sustainable development in Bangladesh

Purpose – Bangladesh is one of the most disaster‐prone countries in the world. Natural disasters adversely affect the countrys economy and deter its development. Thus preparedness for the disasters, along with effective prevention and mitigation measures, is imperative for sustainable development of the country. The purpose of this paper is to examine the present state of disaster preparedness in the country with special attention to the more frequent and damaging disasters – flood and cyclone.Design/methodology/approach – A detailed study of the effects of natural disasters, disaster prevention and mitigation measures, and institutional setting for disaster preparedness was undertaken.Findings – Plans and programs have been formulated to manage natural disasters. In a “Cyclone Preparedness Program”, trained volunteers facilitate emergency response and proper use of the multi‐purpose shelters. Within an institutional framework for disaster management, several Non‐Government Organizations (NGOs) work for ...

Urbanization, peri-urban water (in)security and human well-being: a perspective from four South Asian cities

This paper examines the implications of urbanization for water security and human health and well-being in four peri-urban South Asian locations, namely Khulna in Bangladesh, Kathmandu in Nepal, and Gurgaon and Hyderabad in India. It describes the implications of the urbanization process for water access in communities in the peripheral areas of cities. It further discusses the implications of this for the health and well-being of peri-urban residents.

Social learning for adaptive delta management: Tidal River Management in the Bangladesh Delta

ABSTRACT The article analyzes Tidal River Management in Bangladesh from a social learning perspective. Four cases were investigated using participatory assessment. Knowledge acquisition through transformations in the Tidal River Management process was explored as an intended learning outcome. The study finds that social learning occurred more prominently at the individual stakeholder level and less at the collective level. For Tidal River Management to be responsive and sustainable, especially in times of increased uncertainty and climate vulnerability, more attention needs to be paid to coordination and facilitation of multi-level learning that includes all stakeholders.

Development of a sustainable livelihood security model for storm-surge hazard in the coastal areas of Bangladesh

Coastal communities in Bangladesh are at great risk due to frequent cyclones and cyclone induced storm-surges, which damages inland and marine resource systems. In the present research, seven marginal livelihood groups including Farmers, Fisherman, Fry (shrimp) collectors, Salt farmers, Dry fishers, Forest resource extractors, and Daily wage labourers are identified to be extremely affected by storm- surges in the coastal area of Bangladesh. A livelihood security model was developed to investigate the security status of the coastal livelihood system in a participatory approach. In the model, livelihood security consists of five components: (1) Food, (2) Income, (3) Life & health, (4) House & properties, and (5) Water security. Analytical hierarchy process was followed to assess the livelihood security indicators based on respondents’ security options. The model was verified through direct field observation and expert judgment. The Livelihood Security Model yields a Livelihood Security Index which can be used for assessing and comparing the household security level (in %) of different livelihood groups in the storm-surge prone coastal areas. The model was applied with data from two major coastal areas (Cox’s Bazar and Satkhira) of Bangladesh and is applicable to other coastal areas having similar settings.

Hydrochemistry, water quality and land use signatures in an ephemeral tidal river: implications in water management in the southwestern coastal region of Bangladesh

Despite its complexity and importance in managing water resources in populous deltas, especially in tidal areas, literatures on tidal rivers and their land use linkage in connection to water quality and pollution are rare. Such information is of prior need for Integrated Water Resource Management in water scarce and climate change vulnerable regions, such as the southwestern coast of Bangladesh. Using water quality indices and multivariate analysis, we present here the land use signatures of a dying tidal river due to anthropogenic perturbation. Correlation matrix, hierarchical cluster analysis, factor analysis, and bio-geo-chemical fingerprints were used to quantify the hydro-chemical and anthropogenic processes and identify factors influencing the ionic concentrations. The results show remarkable spatial and temporal variations (p < 0.05) in water quality parameters. The lowest solute concentrations are observed at the mid reach of the stream where the agricultural and urban wastewater mix. Agricultural sites show higher concentration of DO, Na+ and K+ reflecting the effects of tidal spill-over and shrimp wastewater effluents nearby. Higher level of Salinity, EC, Cl−, HCO3−, NO3−, PO43− and TSS characterize the urban sites indicating a signature of land use dominated by direct discharge of household organic waste into the waters. The spatial variation in overall water quality suggests a periodic enhancement of quality especially for irrigation and non-drinking purposes during monsoon and post-monsoon, indicating significant influence of amount of rainfall in the basin. We recommend that, given the recent trend of increasing precipitation and ground water table decrease, such dying tidal river basins may serve as excellent surface water reservoir to supplement quality water supply to the region.
