A suffocating blanket of smog has descended across large swathes of Indonesia, staining the sky an eerie yellow and sparking urgent fears for the safety of children. The hazardous air, driven by widespread forest and peatland fires on the islands of Sumatra and Kalimantan, has forced the closure of hundreds of schools and prompted health authorities to issue stark warnings about the long-term impact on young lungs. Parents have described the atmosphere as “our world is yellow”, a phrase that has resonated across social media as families struggle to protect their children from the invisible threat.
**Context**
Indonesia’s annual dry season has once again brought a devastating haze crisis, a recurring environmental and public health emergency that has plagued the archipelago for decades. The fires, often started illegally to clear land for palm oil and pulpwood plantations, release vast quantities of fine particulate matter (PM2.5) and toxic gases. These pollutants penetrate deep into the respiratory system, causing immediate symptoms such as coughing, eye irritation and difficulty breathing, while prolonged exposure is linked to reduced lung function, developmental delays and increased risk of chronic disease.
This year’s episode has been particularly severe. Satellite imagery from the ASEAN Specialised Meteorological Centre shows hotspots concentrated in the provinces of Riau, Jambi, South Sumatra and Central Kalimantan. The Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG) has reported that visibility in several cities has dropped to under 100 metres, disrupting air travel and daily life. The capital Jakarta, while not directly in the path of the worst smoke, has experienced a noticeable deterioration in air quality, with readings on independent monitors frequently exceeding levels considered safe by the World Health Organisation.
Children are the most vulnerable. Their lungs are still developing, they breathe more rapidly than adults, and they spend more time outdoors. The Indonesian Paediatric Society has repeatedly warned that even short-term exposure to such dense smog can trigger asthma attacks, bronchitis and other acute respiratory infections. In the worst-affected areas, paediatric wards are overflowing with young patients suffering from severe respiratory distress. Schools have been ordered to suspend classes, with many converting into makeshift health posts where nurses distribute face masks and conduct basic check-ups.
**Analise**
The current crisis is not merely a seasonal nuisance; it is a systemic failure of governance and environmental stewardship. Despite decades of pledges to tackle the root causes of the fires, enforcement of land-clearing bans remains weak, and powerful corporate interests continue to operate with impunity. The economic cost is staggering: lost productivity, healthcare expenses, and damage to tourism and aviation run into billions of dollars each year. But the human cost, measured in the stolen futures of children who grow up breathing poisoned air, is incalculable.
For the United Kingdom, this story carries a dual significance. First, many of the commodities driving the fires – palm oil, paper, rubber – are imported by British companies and consumers. Campaign groups have long urged UK retailers to adopt stricter supply chain due diligence to ensure they are not complicit in environmental destruction. Second, the haze crisis is a stark reminder that air pollution knows no borders. Smoke from Indonesian fires has previously drifted as far as Malaysia, Singapore and southern Thailand, causing diplomatic tensions and regional health emergencies. As climate change intensifies droughts and fire seasons, such transboundary pollution events are likely to become more frequent and severe.
There is also a growing recognition that the health impacts of air pollution are a matter of national security. Chronic respiratory illness weakens the workforce, strains healthcare systems and exacerbates social inequalities. In Indonesia, the poorest communities – those living closest to the fire fronts and with the least access to medical care – bear the brunt of the crisis. The government has distributed millions of masks and set up air filtration centres, but these are stopgap measures. Without a fundamental shift towards sustainable land management and renewable energy, the yellow skies will return year after year.
