Lithuania is restoring Soviet-era drained peat bogs to lock away carbon and create a natural barrier against armored vehicles. The spongy soil cannot support tanks, forcing invading forces onto roads where they are more vulnerable. Officials say the project is cheaper than tank ditches or minefields and also helps meet climate goals. Peat bogs are highly efficient carbon sinks, storing more carbon per acre than forests. Restoring them prevents CO2 release from dried peat and reestablishes waterlogged conditions that halt decomposition. Lithuania, Latvia, and Finland are all pursuing similar dual-use bog restoration for climate and defense. The article notes that Ukrainian bogs helped delay Russian troops in 2022. With only one major highway from Minsk to Vilnius, restored bogs could channel any invasion force into predictable kill zones. The project shows how nature-based solutions can serve both climate and security objectives.
