India Dominates List of Most Polluted Cities as Global Air Quality Crisis Deepens
A new report has revealed that India is home to six of the world’s nine most polluted cities, highlighting the severity of the country’s air quality crisis. The findings, published by Swiss-based air quality database IQAir, analyzed data from 40,000 monitoring stations across 138 countries, identifying India, Chad, Congo, Bangladesh, and Pakistan as having the dirtiest air globally.
The industrial town of Byrnihat in northeastern India was ranked as the most polluted city worldwide, underlining the impact of rapid industrialization and emissions from factories and vehicles.
A Global Crisis: 83% of Cities Fail Air Quality Standards
The report painted a grim picture of global air pollution, revealing that only 17% of cities worldwide meet air quality guidelines set by the World Health Organization (WHO). Experts warned that actual pollution levels could be even worse, as vast regions, particularly in Africa, lack adequate monitoring infrastructure.
Currently, Africa has only one air quality monitoring station for every 3.7 million people, making it difficult to assess the true extent of pollution. However, progress is being made, with 8,954 new monitoring locations and nearly 1,000 additional sensors deployed in the past year to improve air quality tracking.
Despite these advancements, efforts to monitor pollution suffered a setback last week when the US State Department announced it would stop publicly sharing air quality data from its embassies and consulates worldwide. This move could impact the ability of researchers and policymakers to track pollution levels in some of the world’s most affected regions.
Health Risks of Air Pollution: A Silent Killer
Long-term exposure to polluted air is linked to a range of severe health issues, including respiratory diseases, Alzheimer’s, and cancer, according to Fatimah Ahamad, chief scientist at Malaysia-based Sunway Centre for Planetary Health.
The WHO estimates that air pollution causes around 7 million deaths annually, making it one of the leading environmental health threats.
Ahamad emphasized that urgent action is needed to tackle air pollution, pointing out that nearly 99% of the world’s population lives in areas failing to meet recommended air quality standards.
“If you have bad water, you can tell people to wait for a few hours to get clean water. But if you have bad air, you cannot tell people to stop breathing,” she said.
How Cities Are Fighting Back
While the crisis remains severe, some cities have successfully improved air quality through strict regulations and clean energy initiatives.
- Beijing, Seoul, and Rybnik (Poland) have implemented stricter controls on vehicle emissions, power plants, and industrial pollution while promoting public transport and renewable energy.
- In Southeast Asia, the ASEAN agreement on transboundary haze pollution aims to curb pollution from forest fires, though its success has been limited so far.
Air Pollution and Climate Change: A Common Battle
Shweta Narayan, a campaign lead at the Global Climate and Health Alliance, stressed that regions with the worst air pollution are often the same places where large amounts of greenhouse gases are emitted from burning coal, oil, and gas.
“Air pollution and climate change are two sides of the same coin,” Narayan said, adding that reducing fossil fuel use would not only slow global warming but also improve air quality and public health worldwide.

Global Mental Health Cases Near 1.2 Billion as Anxiety and Depression Drive Sharp Worldwide Rise
A major global analysis has found that mental health conditions have surged to an estimated 1.2 billion people worldwide, driven largely by steep increases in anxiety and depression over the past three decades.
The findings, published in The Lancet as part of the Global Burden of Disease Study 2023, show that the number of people living with mental disorders has almost doubled since 1990, marking a 95% rise. Researchers say major depressive disorder and anxiety disorders have seen even sharper growth, increasing by 131% and 158% respectively, making them the most prevalent mental health conditions globally.
The report describes mental illnesses as widespread conditions that create long-term disability and significant human suffering. It also highlights broader consequences for economies and public services, including reduced productivity, lower workforce participation and increasing pressure on health and welfare systems.
Researchers estimate that in 2023 alone, around 620 million females and 552 million males were affected by mental health conditions. While the overall burden is rising across both sexes, the study points to notable differences in the types and prevalence of disorders.
Among women, depression and anxiety were the most commonly reported conditions, alongside higher rates of eating disorders such as anorexia nervosa and bulimia nervosa. The report links this disparity to a mix of biological, social and structural factors, including exposure to domestic violence, sexual abuse, gender inequality and reproductive health-related changes.
In contrast, neurodevelopmental and behavioural disorders, including attention deficit hyperactivity disorder (ADHD), conduct disorder and autism spectrum conditions, were more frequently diagnosed in men.
Teenagers aged 15 to 19 were identified as the group experiencing the highest mental health burden globally, raising concerns about early onset of conditions and insufficient preventive care for young people.
The study identifies several key risk factors associated with mental illness, including childhood sexual violence, bullying and intimate partner violence. These factors are strongly linked to conditions such as depression, schizophrenia, bipolar disorder and anxiety disorders. However, researchers note that such exposures have remained relatively stable over time and account for only a portion of the overall rise.
According to the authors, broader drivers are likely contributing to the increasing prevalence of mental disorders. These include genetic and biological influences, poverty, inequality, and the growing impact of global crises such as armed conflict, pandemics, natural disasters and climate-related stress.
While mental health conditions have long been a leading cause of disability worldwide, the report warns that the situation is worsening. At the same time, health systems have not expanded services at a pace matching demand.
The authors caution that the gap between rising need and limited access to care is becoming more pronounced, leaving millions without adequate treatment or support.
