Dhaka Navigates Traffic Congestion Air Quality Concerns Amid Development

Dhaka, Bangladesh – The bustling metropolis of Dhaka continues to grapple with familiar challenges – traffic congestion and deteriorating air quality – even as the city undergoes significant infrastructural development. Recent weeks have seen a renewed focus from city authorities on addressing these issues, alongside ongoing projects aimed at improving the overall urban experience for its over 22 million residents.

Traffic remains a persistent problem, particularly during peak hours. A combination of factors contributes to the gridlock, including a high density of vehicles, inadequate public transportation options, and ongoing road construction. The Dhaka Metropolitan Police (DMP) has been implementing revised traffic management plans, including adjusted signal timings and increased deployment of traffic officers, but the impact has been limited. Several ongoing elevated expressway projects, including the Dhaka Elevated Expressway, promise long-term relief, but construction itself exacerbates congestion in the short term. The first phase of the expressway, from Kawla to Farmgate, has partially opened, offering a limited bypass for some commuters, however full completion is still some time away.

Air quality in Dhaka consistently ranks among the worst in the world, particularly during the winter months. Recent data from the Department of Environment (DoE) indicates that levels of particulate matter (PM2.5) frequently exceed safe limits, posing significant health risks to residents. Construction activities, brick kilns, vehicular emissions, and seasonal factors all contribute to the pollution. The DoE has been conducting mobile court drives targeting illegal brick kilns and vehicles emitting excessive smoke, but enforcement remains a challenge. Experts advocate for stricter emission standards, investment in cleaner public transport, and increased green spaces to mitigate the problem. A recent study by the World Bank highlighted the economic cost of air pollution in Dhaka, estimating billions of dollars lost annually due to healthcare expenses and reduced productivity.

Beyond these ongoing concerns, Dhaka is witnessing substantial development across various sectors. The Mass Rapid Transit (MRT) Line 6, commonly known as the Dhaka Metro, is operational and transporting thousands of passengers daily, offering a much-needed alternative to road travel. Plans are underway to expand the metro network with additional lines, including MRT Line 1 and MRT Line 5, aiming to connect different parts of the city and reduce reliance on private vehicles. These expansions are funded with assistance from the Japan International Cooperation Agency (JICA) and the Asian Development Bank (ADB).

Furthermore, several infrastructure projects aimed at improving water supply and sanitation are underway, addressing long-standing issues of waterlogging and inadequate access to clean water. The Dhaka Water Supply and Sewerage Authority (Wasa) is implementing various initiatives, including the construction of new water treatment plants and the rehabilitation of existing infrastructure. However, progress has been slow, and challenges remain in ensuring equitable access to these essential services across all communities.

Recent heavy rainfall has also exposed vulnerabilities in the city’s drainage system, leading to widespread waterlogging in many areas. City authorities are working to improve drainage capacity, but the rapid pace of urbanization and unplanned construction continue to strain the system. Experts suggest integrating green infrastructure, such as permeable pavements and urban wetlands, into urban planning to enhance drainage and reduce the risk of flooding.

Looking ahead, the Dhaka city authorities face a complex task of balancing economic development with environmental sustainability and the well-being of its residents. Effective urban planning, robust enforcement of regulations, and significant investment in public infrastructure and services will be crucial to address the challenges and create a more livable city for all.
