Two Dhaka, Bangladesh, landfills are explored to understand how management practices impact environmental quality and public health in the surrounding areas. A combination of research methods is used, such as geospatial buffer zone analysis, semi-structured observation checklist and qualitative interviews, to gain an understanding of the waste transportation, leachate percolation, and adverse health and environmental effects. A multi-ring buffer zone and ground truth method were applied through ArcMap for the spatial distribution of landfill-adjacent environmental features. Qualitative interviews were conducted with landfill officials and nearby residents. Findings reveal that landfills are situated very close to residential areas, water bodies and agricultural lands, exposing them to various health and environmental hazards. Improper solid waste management practices of the landfills cause adverse environmental effects by leachate percolation, waste incineration and vector breeding. Adjacent dwellers suffer from bronchial diseases, pneumonia, diarrhoea, itching problems, headache and appetite loss. The existing solid waste management system requires managerial and technical modifications to reduce the associated environmental pollution and health hazards. PRACTICE RELEVANCEWaste management practices impact directly on environmental and public health. Dhaka's existing waste management practices can become better organised to address these concerns. Source waste reduction must be implemented to ensure the reduction of disposed waste at landfills. Administrative capacity of landfills requires

Issues Solid waste management is one of the biggest concerns in Bangladesh, particularly in Dhaka city at present. This paper aims to find the gaps and challenges in solid waste management policies and implementations and thus, gives an insight towards sustainable solid waste management system in the country. Description of the Problem Improper solid waste management is adversely impacting environmental protection, public health and the control of carbon emissions in Bangladesh. As a result solid waste has become a major area of public policy with growing concern. Lessons Bangladesh has been experiencing changes in solid waste management since 1983 with the introduction of Dhaka City Corporation Ordinance and later the promulgation of National 3R Policy in 2010. With few exceptions, the overall waste management system cannot be termed as an efficient sequential process of waste minimization, recycling, and disposal based on global standards. Many initiatives are being implemented as part of independent projects by the non-governmental organizations (NGOs) and not always supported by policies. Though the establishment of several secondary transfer stations (STSs) has improved the environmental conditions and cleanliness of the cities, the waste segregation and recycling practices in the pathways from households to landfill do not adhere to the 3R Policy. Both the recyclable and non-recyclable waste are collected and dumped all together at different levels of waste management, i.e. collection from households, dumping at STSs, and later in the landfill without any formal procedures of sorting and recycling. Lack of coordination between implementing agencies is another problem. Conclusions Absence of sustainable solid waste management policy and proper execution agency are the main obstacles towards a proper waste management system. This problem is huge and should be addressed immediately to protect the environment and ensure better health of the city population. Key messages Even though the formation of STSs is one of the significant changes in the system nowadays, it is not evaluated or monitored under any specific policy or ordinance. In order to implement the existing policies, adequate funding and monitoring bodies should be introduced to the waste management sector.

Background Proper management of increasing solid waste is a major challenge for Dhaka city. Hence, the consequences on health are numerous and depend on the nature of the waste, individuals exposed, duration of exposure and availability of interventions for those exposed. This study seeks to identify the potential health risk associated with contamination from STSs and landfills in Dhaka city. Methods This study has adopted a multi-method approach that includes qualitative data collection and analysis of secondary spatial data. Thematic analysis was performed for analysing the qualitative data and. Spatial data were collected from the Survey of Bangladesh and analysed to show the spatial distribution of 68 STSs out of 81 STSs in Dhaka City. Results Qualitative study suggests that the leachate migration from the landfill and STSs make the surrounding environment worse and causes health sufferings to the people living near the STS or landfill along with the people directly working. Furthermore, findings from the spatial data reveal that, 12 STSs within 50-100 meters and 54 STSs within 100 meters radius of an education institute and round 75 STSs are also located within 100 meters radius of the health facilities. Numerous settlements and natural features are also located within 500 meters of buffer zone from the both landfills. Flies and mosquitoes are breeding at a greater pace in and around the landfills where high quantities of solid waste are being dumped. Again, waterlogging is very common due to the dumping of waste which in turn is causing the spread of dengue and other water borne diseases in the surrounding area. Conclusions Poor management and incautious allocation of the STSs and landfills have adverse effects on the people's health residing nearby. Managing waste in the landfill and STS with a proper manner, and engaging more manpower with adequate safety equipment could be a great help to reduce the health sufferings of the people living nearby. Key messages Improper solid waste management practice effects on the health of people residing near the STSs and landfills. To manage the waste of the STSs and landfills in an efficient way and not cause daily nuisance to the nearby residents.
