"ensure the full incorporation and effective implementation within national legislation of the international humanitarian law prohibition against the starvation of civilians as a method of warfare, explicitly criminalising any conduct that attacks, destroys, removes, or renders useless objects indispensable to the survival of the civilian population."
Additional Protocols I and II specify "objects indispensable to the survival of the civilian population" rather than "property vital." They define deprivation broadly to include attacking, destroying, removing, or rendering these objects useless.
