Urbanization and sustainability: challenges and strategies for sustainable urban development in Bangladesh 总被引:1,自引:0,他引:1
Md. Masud Parves Rana 《Environment, Development and Sustainability》2011,13(1):237-256
Like other developing countries, urbanization in Bangladesh is a growing phenomenon, which is steady in nature but fretfully
affects urban sustainability in the wake of lacking in good governance. Despite urban authorities are concerned about this
issue, they often fail to address the problems due to the fact of uncontrollable and unpredictable rural to urban migration,
and negligence of urban poor’s sustainable living and access to basic services. Virtually the rural poverty problem has been
transposed to urban areas, particularly in Dhaka City, Bangladesh. Inadequacy of infrastructural services, basic amenities
and environmental goods; environmental degradation; traffic jam and accidents; violence and socioeconomic insecurity are the
major challenges which are created through rapid urbanization. This paper provides a general understanding of urbanization
in Bangladesh and tries to embrace related sustainability issues and challenges hindrance to sustainable urban development
in Dhaka city. In addition, it presents a brief case study of water supply in Dhaka city which introduces an issue of ‘system
hijack’. The paper concludes providing some strategies that might be helpful to the policy makers in formulating development
policies for sustainable urban services. 相似文献

Effective safety measures to prevent and mitigate the consequences of an accidental release of flammable LNG are critical. Water spray curtain is currently recognized as an effective technique to control and mitigate various hazards in the industries. It has been used to absorb, dilute and disperse both toxic and flammable vapor cloud. It is also used as protection against heat radiation, in case of fighting vapor cloud fire. Water curtain has also been considered as one of the most economic and promising LNG vapor cloud control techniques. Water curtains are expected to enhance LNG vapor cloud dispersion mainly through mechanical effects, dilution, and thermal effects. The actual phenomena involved in LNG vapor and water curtain interaction were not clearly established from previous research. LNG spill experiments have been performed at the Brayton Fire Training Field at Texas A&M University (TAMU) to understand the effect of water curtain in controlling and dispersing LNG vapor cloud. This paper summarizes experimental methodology and presents data from two water curtain tests. The analysis of the test results are also presented to identify the effectiveness of these two types of water spray curtains in enhancing the LNG vapor cloud dispersion. 相似文献

The paper deals with bacterial and fungal populations and other pollutants in the indoors of slums, middle class, and upper class dwellings. Both allergenic and nonallergenic organisms have been observed to be higher in slums than in other dwellings. Further, females were more susceptible to various kinds of allergies than males. 相似文献

Data from two cross-sectional surveys totaling over 2000 farmers in Pakistan are analyzed with regression techniques to estimate the value productivity of irrigation water and related resources. Returns to irrigation water vary by province, but in general are found to be high relative to estimated costs of obtaining water. Salinity of water supplies is an important productivity depressant. The results will be useful in determining the economic feasibility of various means for augmenting supplies and for improving delivery and application efficiencies. 相似文献

This study explores the relationship between daylight exposure in urban residential units and the mood/happiness of nonworking female residents (housewives) in Isfahan, Iran. A growing body of evidence points to the physiological and psychological benefits of daylight, yet few studies have focused on the relationship between residential daylight and women's mental health. A cross‐sectional study was conducted using two‐stage random cluster sampling of nonworking female occupants of buildings in four residential districts. Mood/happiness was determined using the Oxford Happiness Inventory and the Fordyce Happiness Inventory. Spearman's rank correlation analysis was used to determine the relationship between the variables. A significant relationship was found between residents’ happiness and the amount of daylight in their residential units (Oxford Inventory, r = 0.68, P < 0.05; Fordyce Inventory, r = 0.53, P < 0.05). The findings suggest that features of physical residential environments, such as daylight, may be linked to the happiness of housewives. Persons belonging to various demographic groups who spend the majority of their time indoors (e.g., housewives, children, elderly individuals, and people with disabilities) are most dependent on architecture and environmental design for their well‐being, and therefore, are most affected by design decisions. 相似文献

A series of oxime esters was synthesized by esterification of 3-ethoxy-4-benzaldehyde oxime with acid chlorides in the presence of triethylamine. They were evaluated for their in vitro antifungal activity against three pathogenic fungi, namely Rhizoctonia bataticola, Fusarium udum, and Alternaria porii, and their antibacterial activity against the three bacterial strains Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoneae. The compounds bearing medium-length alkyl chains showed greater activity than those with long alkyl chains. An electron-donating group in para position of the aryl ring confers highest activity. 相似文献
