'Our World is Yellow': Fears Grow for Children as Toxic Smog Engulfs Indonesia

**Lead**

A suffocating blanket of toxic smog has descended across Indonesia’s main islands of Sumatra and Kalimantan, turning the midday sky a sickly yellow and forcing the closure of thousands of schools. Parents and health workers are voicing deep alarm over the impact on children, who are most vulnerable to the fine particulate matter that now hangs in the air for weeks on end. The phenomenon, which has become an annual ordeal, has this year reached particularly severe levels, prompting comparisons with the worst episodes of the past decade. Officials have declared a state of emergency in several provinces, and the national government has scrambled to deploy water-bombing aircraft and artificial rain technology, but the scale of the crisis appears to be outstripping these efforts.

**Context**

The smog originates primarily from the deliberate burning of peatland and forest to clear land for palm oil and pulpwood plantations. This practice, known as slash-and-burn agriculture, is illegal under Indonesian law but remains widespread due to weak enforcement and the economic pressures on smallholders and large corporations alike. This year’s particularly severe haze has been exacerbated by a prolonged dry season linked to the El Niño weather pattern, which has left vast stretches of peatland tinder-dry and highly flammable. Satellite imagery from the region shows thousands of fire hot spots, with smoke plumes drifting across national borders, affecting neighbouring Malaysia and Singapore as well.

Local health officials have reported a sharp increase in the number of patients seeking treatment for acute respiratory infections, eye irritation, and skin conditions. Children, whose lungs are still developing and who breathe more rapidly than adults, are disproportionately affected. Preliminary assessments from aid organisations on the ground indicate that many schools have been forced to close for weeks, disrupting the education of millions of pupils. Parents are keeping their children indoors, but homes without adequate air filtration offer little protection from the microscopic particles that infiltrate every crevice.

**Analysis**

The health implications of this recurring crisis are profound and long-lasting. Medical experts specialising in paediatric respiratory health have drawn attention to the risk of chronic lung disease, reduced lung capacity, and increased susceptibility to infections later in life. Beyond the immediate physical toll, there is growing concern about the psychological impact on children who are living under a constant pall of smoke, unable to play outside or attend school normally. The economic cost, too, is staggering: lost school days, reduced worker productivity, and increased healthcare expenditure place an enormous burden on local communities and the national budget.

From a scientific perspective, the Indonesian smog crisis is not merely a local environmental disaster but a stark symptom of global climate breakdown. The same warming trends that intensify drought conditions also make peatland fires more likely and more destructive. Carbon emissions from these fires further accelerate climate change, creating a vicious feedback loop. For the United Kingdom, where air quality standards are far higher, the crisis serves as a cautionary tale. British scientists have long studied the transboundary movement of pollutants and the health effects of particulate matter, and UK-based research institutions have collaborated with Indonesian counterparts on peatland restoration projects. The situation in Indonesia underscores the urgency of international efforts to phase out deforestation-linked commodities and to support sustainable land management in tropical regions.
