scorched-earth

A scorched earth policy is a military strategy that involves

destroying anything that might be useful to the enemy 

while advancing through or withdrawing from an area. It

is a military strategy where all of the assets that are used

or can be used by the enemy are targeted, such as food 

sources, transportation, communications, industrial 

resources, and even the people^{[citation needed]} in the 

area. The practice can be carried out by the military in 

enemy territory, or in its own home territory. It may 

overlap with, but is not the same as, punitive destruction 

of the enemy's resources, which is done for purely 

strategic/political reasons rather than strategic/operational

 reasons.

The strategy of destroying the food and water supply of the civilian population in an area of conflict has been banned under Article 54 of Protocol I of the 1977 Geneva Conventions. The relevant passage says:

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]
