Scorched earth

A scorched-earth policy is a military strategy of destroying everything that allows an enemy to be able to fight a war, including water, food, humans, animals, plants and any kind of tools and infrastructure. Its use is possible by a retreating army to leave nothing of value to the attacking force or by an advancing army to fight against unconventional warfare.[1]

Scorched earth against non-combatants has been banned under the 1977 Geneva Conventions.[lower-alpha 1]

It is prohibited to attack, destroy, remove, or render useless objects indispensable to the survival of the civilian population, such as foodstuffs, agricultural areas for the production of foodstuffs, crops, livestock, drinking water installations and supplies, and irrigation works, for the specific purpose of denying them for their sustenance value to the civilian population or to the adverse Party, whatever the motive, whether in order to starve out civilians, to cause them to move away, or for any other motive.[2]
