This article analyses two situations currently endangering water security in Donbass and Crimea, highlighting the international law obligations of the actors involved. First, the article analyses the ongoing armed conflict in Donbass, exploring what responsibilities may be envisaged under the applicable rules of international humanitarian law and international criminal law for the actors involved in the continuous attack and damaging of water facilities. Second, the article focuses on the legality of Ukraine’s decision to block the North Crimea Canal, thereby stopping the flow of water towards the occupied territory of Crimea. The question is whether this action can be qualified as a lawful sovereign decision or whether there are international rules limiting Ukraine’s discretion. The article analyses the legal obligations of both Ukraine and the Russian Federation under general international law, international humanitarian law and human rights law.

顿巴斯和克里米亚的供水：对水基础设施的攻击和对北克里米亚运河的封锁

本文分析了目前正在顿巴斯和克里米亚危及水安全的两种情况，强调了有关行为者的国际法义务。首先，本文分析了顿巴斯正在进行的武装冲突，探讨了根据国际人道法和国际刑法的适用规则，对参与不断袭击和破坏水设施的行为者应承担的责任。第二，本文重点讨论乌克兰决定封锁北克里米亚运河，从而阻止水流向克里米亚被占领领土的合法性。问题是该行动是否可以被视为一项合法的主权决定，或者是否存在限制乌克兰自由裁量权的国际规则。
