Explosive Remnants of War (ERW) refer to unexploded ordnance, such as bombs, shells, and landmines, that remain after armed conflicts. These dangerous items can pose significant risks to civilians, as they may detonate unexpectedly, causing injuries or fatalities. ERW can be found in various environments, including urban areas and agricultural land, making them a persistent threat long after hostilities have ended. Efforts to address ERW include clearance operations and public awareness campaigns. Organizations like the United Nations and various non-governmental organizations work to remove these hazards and educate communities about the dangers of ERW. Proper management and disposal are crucial to ensuring safety and promoting recovery in affected regions.
