Prevent transboundary haze air pollution
Smoke haze levels tend to rise due to intense heat during March, April, and May each year. In years with extremely hot and dry weather conditions, fire hotspots occur more frequently. To effectively prevent and control transboundary haze pollution along the Myanmar-Thailand border, relevant authorities from both countries are making concerted efforts to implement measures aimed at reducing cross-border smoke haze.
Transboundary haze air pollution is a frequent occurrence among neighbouring countries that share borders. To reduce fire hotspots and control cross-border haze pollution, priority areas are designated based on the number and density of fire hotspots in the respective regions and states. Continuous efforts must be undertaken, including shifting from slash-and-burn cultivation to highland farming, producing organic fertilizer from agricultural waste, preventing the careless use of fire in forests, and establishing response plans in the event of haze pollution.
Smoke haze air pollution severely affects public health; therefore, more effective approaches must be sought to successfully implement measures for reducing fire hotspots and controlling haze pollution as a national responsibility. Awareness-raising activities are being carried out by the Ministry of Border Affairs. Such awareness-raising programmes on the prevention of transboundary haze pollution have been conducted at departments and schools.
Smoke haze is mainly caused by the burning of fields after harvest in shifting cultivation areas and by forest fires. Each year, particularly in March and April, people in the border areas of Myanmar, Thailand, and Laos experience the impacts of air pollution. Fine particulate matter (PM2.5) present in the haze can lead to respiratory problems, eye irritation, and lung diseases, posing particular risks to children and the elderly.
In Myanmar, the average annual number of fire hotspots typically ranges from over 37,000 to more than 56,000. Most of these hotspots, caused by forest fires and land clearing for agriculture —particularly slash-and-burn cultivation — are found in Shan State and Sagaing Region. The number of fire hotspots recorded nationwide was 51,091 in 2024 and 45,025 in 2025, representing a decrease of 6,066 cases, or about 12 per cent. Efforts are underway to achieve a reduction of up to 20 per cent in 2026.

Every country places great importance on ensuring that its citizens live long and healthy lives free from illness. As this is not an issue that can be addressed by a single country alone, all neighbouring countries must actively cooperate and participate. To enable everyone to live in good health and well-being, efforts to prevent and control transboundary haze air pollution must be carried out without fail.
