Haze Worsens: Nine Sarawak Areas Hit Unhealthy Air
What happened
Nine locations in Sarawak recorded unhealthy air quality as of 8am on Thursday, according to the Natural Resources and Environment Board's (NREB) Daily Haze Watch. Serian and Lubok Antu registered the highest Air Pollutant Index (API) readings at 185 each. Kuching recorded 180, followed by Lundu at 175 and Sri Aman at a lower level.
The readings indicate a widespread haze episode affecting multiple districts across the state. The NREB's daily monitoring shows the air quality deteriorating across central and southern Sarawak.
Why it matters
An API reading above 100 is classified as unhealthy, and levels above 200 are considered very unhealthy. Readings of 185 place Serian and Lubok Antu in the unhealthy range, posing health risks to residents. Prolonged exposure to such air quality can cause respiratory issues, especially for children, the elderly, and those with pre-existing conditions.
The haze also disrupts daily activities, including school sessions and outdoor work. Businesses in affected areas may see reduced productivity and increased health-related costs.
Impact on Malaysia
Sarawak is a key economic region for Malaysia, with significant agriculture, tourism, and natural resource sectors. Haze events can deter tourists and affect crop yields, particularly for smallholders. The state government may need to activate haze response plans, including distributing masks and advising residents to stay indoors.
The recurrence of haze underscores ongoing environmental challenges in the region, often linked to land and forest fires. This could lead to calls for stricter enforcement of fire prevention regulations.
Regional context
Haze in Sarawak is frequently caused by smoke from land clearing and peat fires, both within Malaysia and neighboring Indonesia. Transboundary haze has been a recurring issue in Southeast Asia, affecting air quality across the region. The current episode aligns with the dry season, when fires are more common.
Previous haze events have led to regional cooperation efforts, such as the ASEAN Agreement on Transboundary Haze Pollution. However, implementation and enforcement remain inconsistent.
Government response
The NREB is the primary agency monitoring air quality in Sarawak and issuing daily haze updates. Local authorities may issue health advisories and recommend precautionary measures. Schools in affected areas could suspend outdoor activities if API levels rise further.
Residents are advised to limit outdoor activities, use air purifiers indoors, and wear masks when going out. The state disaster management committee may convene if conditions worsen.
Outlook
Air quality is expected to fluctuate depending on wind direction and fire activity. The NREB will continue to publish daily API readings. If readings exceed 200, the situation could escalate to a very unhealthy level, triggering more aggressive responses.
Long-term solutions require addressing the root causes of land and forest fires, including sustainable land management and regional cooperation. Until then, haze episodes are likely to recur during dry seasons.
