Part of El Nino is causing drought conditions in Sumatra and Kalimantan, leading to increased fire risk and smoke affecting Malaysia.

How could transboundary smoke affect agricultural productivity in Sabah?

Possible What happens if… A possibility worth considering, not a forecast.

Transboundary smoke may reduce crop yield and quality in Sabah's agricultural areas. Transboundary smoke originating from critical source areas like Kalimantan and Sumatra has been reported to affect parts of Malaysia and Borneo. This haze poses a food security risk because pollutants, including particulate matter, can reduce photosynthesis, growth, and overall crop quality. While the reports do not quantify the specific impact on Sabah, the general mechanism shows that exposure to this polluted air can negatively affect crops of economic importance, such as rubber, oil palm, and vegetables.

How it reaches Sabah

Tap any step to see the evidence behind it.

The facts so far

As reported. Each one links to where it comes from.

  • By Sep 30, 2026, the main active haze problem shifted to maritime Southeast Asia, with Kalimantan and Sumatra becoming critical source areas of smoke, affecting parts of Malaysia, Singapore and Borneo.channelnewsasia.com
  • Poor air quality can reduce photosynthesis, growth, yields and crop quality.channelnewsasia.com
  • An indicative estimate suggests approximately 50 to 70 million ha of cropland—roughly 40 to 55 per cent of Southeast Asia’s farmland—may have been potentially exposed to significant haze during the major 2026 northern and southern episodes.channelnewsasia.com

Why it matters

For Sabah, which relies on agriculture and resource production, transboundary haze represents a direct threat to food security and economic output. The reports highlight that crops of economic importance, such as oil palm and rubber, are susceptible to damage from air pollution, meaning that haze episodes could translate into reduced harvests and financial losses.

Regionally, this issue is part of a larger polycrisis driven by El Nino conditions, drought, and elevated fire activity in Sumatra and Kalimantan. ASEAN has recognized haze as a transboundary environmental problem, but the reports note that the relevant sectoral plans fail to connect air quality directly with agricultural productivity, leaving a critical gap in quantifying the actual losses.

What we don't know yet

  • What are the specific wind patterns that determine how much smoke reaches Sabah?
  • How sensitive are Sabah's specific crop cultivars to the particulate matter and ozone levels reported?

What would change this answer

Increased monitoring of agricultural exposure is implemented by ASEAN member statesThis would provide localized scientific assessments needed to quantify the actual crop loss in Sabah and other affected areas.
The El Nino conditions subside and fire activity decreasesThe frequency and intensity of transboundary smoke affecting Sabah's agricultural areas would likely decrease.

Beyond this explainer

Questions worth asking

Ideas the web ties closely to this story that the explainer doesn't mention. These are prompts for your own research: Brind hasn't answered them.

  • About Sarawak

    Do agricultural practices or crop types in Sarawak face similar risks from transboundary haze as those in Sabah?

  • About ASEAN Nations

    Since ASEAN recognizes haze as a transboundary problem, what specific mechanisms are in place to enforce air quality standards across member states?
