- The five Mekong countries lost nearly 1 million hectares (2.5 million acres) of tree cover in 2024, with nearly a quarter of which was primary forest, and more than 30% of losses occurring inside protected areas.
- Cambodia and Laos saw some of the highest levels of loss inside protected areas, driven by logging, plantations and hydropower projects, though both countries recorded slight declines from 2023.
- In Myanmar, conflict has complicated forest governance, with mining and displacement contributing to losses, though overall deforestation fell slightly compared to the previous year.
- Thailand and Vietnam bucked the regional trend, with relatively low forest losses in protected areas, supported by logging bans, reforestation initiatives, and stricter law enforcement.

BANGKOK — The Mekong countries of Cambodia, Laos, Myanmar, Thailand and Vietnam lost a combined area of tree cover of nearly a million hectares in 2024, or an area almost the size of Lebanon. That’s according to Mongabay’s analysis* of satellite data published by the Global Land Analysis and Discovery (GLAD) laboratory at the University of Maryland, in partnership with Global Forest Watch (GFW).
GFW data show 991,801 hectares (2.45 million acres) of tree cover were lost in 2024, including nearly 220,000 hectares (544,000 acres) of primary forest, across the five Mekong countries. More than 30% of tree cover loss recorded in 2024 occurred inside protected areas, although across the region, the rate of deforestation — both within protected areas and outside of them — slowed slightly from 2023. Despite this, the drivers of deforestation vary somewhat from country to country, and last year’s losses still reflect a grim trajectory for forests in the Mekong region.
The economies of almost all Mekong countries are heavily reliant on agriculture, with forests cleared for both agribusiness-run plantations or subsistence farming plots. But research indicates the conversion of forest to croplands has resulted in increasingly unpredictable weather patterns and subsequently poorer agricultural yields.
