Conflict-related environmental damage remains a huge challenge. This article provides a brief overview of international humanitarian law (IHL) rules that protect the natural environment in armed conflict and notes some convergences with the rules developed by classical Islamic jurists (those who lived from the seventh century up to the last quarter of the nineteenth century) affording protection to the natural environment. Today, a significant number of International Committee of the Red Cross operations take place in Muslim-majority countries, and some Muslim interlocutors, in particular Islamic non-State armed groups, use Islamic law as their normative framework. For better respect for IHL in relevant Muslim-majority States or territories, considering an Islamic legal approach to the protection of the natural environment alongside IHL would allow the parties to conflicts in such countries to better understand their obligations and should enhance the protection of the natural environment in armed conflict.
