The Thai government, led by Prime Minister Srettha Thavisin, is contemplating a ban on corn imports from neighboring countries to combat the PM2.5 fine dust pollution in northern Thailand. This consideration arose during the prime minister's visit to Chiang Mai, where he reviewed the region's wildfire and haze prevention measures. The proposed ban, aimed at reducing agricultural burning that contributes to pollution, would be in effect from January to April next year. The PM has engaged in discussions with officials from Cambodia, Laos, and Myanmar to address the cross-border aspect of the pollution problem, emphasizing the need for regional cooperation without infringing on sovereignty.
The issue of PM2.5 pollution is linked to economic activities, with farmers in rural areas burning agricultural waste and forests to clear land for new crops or to gather wild resources. This practice has been identified as a major contributor to the hazardous air quality levels in the region. In response, Prime Minister Srettha is advocating for innovative solutions and military involvement to manage agricultural waste more effectively and prevent open burning. He stressed the importance of educating and training farmers on alternative waste management methods to mitigate the pollution crisis.
The Thai government has taken additional steps to address the broader environmental challenges contributing to PM2.5 pollution, including traffic congestion and urban emissions. Despite some improvements in air quality and a reduction in hotspot incidents, cities like Chiang Mai continue to suffer from severe pollution levels, often topping global charts for air pollution.
