Dhaka Grapples with Worsening Air Quality as Winter Approaches

Dhaka, the capital of Bangladesh, is once again facing a severe deterioration in air quality as the winter season sets in, raising alarms among environmentalists and public health experts. According to the latest data from the Air Quality Index (AQI), Dhaka recorded an average AQI score of 198 on Tuesday morning, categorizing the city's air as 'unhealthy' and placing it among the most polluted cities globally. This marks a significant spike from previous weeks, driven by a combination of factors including increased vehicular emissions, construction dust, and the seasonal burning of crop residues in surrounding regions.

The Bangladesh Department of Environment (DoE) has acknowledged the worsening situation, attributing it to the drop in temperature and wind speed that traps pollutants close to the ground. Officials have urged citizens to wear masks and limit outdoor activities, particularly during early morning hours when pollution levels peak. 'The air quality index is expected to remain in the red zone for the next several weeks unless drastic measures are taken,' said Dr. Shahidul Islam, a senior environmental scientist at the DoE. 'We are monitoring the situation closely and have deployed mobile teams to inspect brick kilns and construction sites that violate emission standards.'

Residents of Dhaka have expressed growing frustration over the recurring crisis. 'Every winter, it's the same story. We can barely breathe, and the government's actions seem too little, too late,' said Fatima Begum, a schoolteacher living in the Mirpur area. Many have resorted to using air purifiers at home and wearing N95 masks outdoors, though the costs remain prohibitive for low-income families. Local hospitals have reported a rise in respiratory cases, with children and the elderly being the most vulnerable.

On the international front, Dhaka's pollution crisis mirrors a broader trend across South Asia, where cities like Delhi, Lahore, and Kathmandu also face hazardous air quality during winter months. Experts point to shared challenges such as rapid urbanization, reliance on fossil fuels, and weak enforcement of environmental regulations. The World Health Organization (WHO) has repeatedly highlighted that air pollution causes an estimated 7 million premature deaths annually worldwide, with Bangladesh being one of the worst-affected countries.

In response to the crisis, the Bangladesh government has announced a series of short-term measures, including intensified monitoring of industrial emissions, stricter controls on vehicular pollution, and a temporary ban on new construction projects in high-density areas. However, activists argue that these steps are insufficient without long-term structural changes. 'We need a comprehensive action plan that includes transitioning to cleaner energy, expanding public transport, and promoting green spaces in the city,' said Rizwan Rahman, a coordinator with the Bangladesh Environmental Lawyers Association (BELA). 'Without political will and community participation, Dhaka's air will remain a public health hazard.'

Meanwhile, the international community has offered support. The United Nations Development Programme (UNDP) has pledged technical assistance for air quality monitoring systems, while the Asian Development Bank (ADB) is financing projects to promote electric vehicles and renewable energy in Bangladesh. Such collaborations are seen as crucial for addressing the transboundary nature of air pollution, which often drifts across borders from neighboring countries.

As the winter deepens, Dhaka's residents brace for more days of smoggy skies and choked lungs. The city's struggle serves as a stark reminder of the urgent need for collective action to combat environmental degradation, both locally and globally. For now, the message from officials and experts remains clear: prioritize health, reduce pollution, and demand accountability.
