The protection of the environment during warfare attracted significant attention in the 1990s, especially after the 1990–91 Gulf War. It became clear at that time that the few rules provided by international humanitarian law (IHL) aimed specifically at protecting the environment were insufficient. Various studies have since been undertaken with the aim of strengthening that protection from an IHL perspective. It is only recently that scholars and institutions like the International Law Commission have started to reflect on how to better protect the environment in armed conflict through the lens of another branch of international law, namely, international environmental law (IEL). Such an approach has involved examining the interplay between IHL and IEL, and scholars have subsequently proposed and then elaborated on frameworks in that respect. This paper intends to identify common trends of those frameworks and to critically appraise them, with the aim of providing a suitable approach to the interplay between IHL and IEL.

Actors engaging in a diverse set of environmental protection activities are experiencing serious difficulties executing their mandates during armed conflict, leading to environmental harm that could otherwise have been mitigated. This article examines to what extent the international legal and policy framework can ensure the protection of environmental protection actors during armed conflict. It is argued that environmental protection actors can be seen either as part of civil defence organizations or as humanitarian relief actors, and are therefore covered by special protections under international humanitarian law. However, two main challenges remain: (1) despite these existing provisions, environmental protection actors may still face access and safety issues during armed conflict, and (2) within this framework, environmental protection activities must be linked to civilian needs and cannot be conducted based on ecocentric motivations. To overcome these challenges, the article introduces the concept of “environmentarian corridors”. Environmentarian corridors would allow for the unimpeded movement of environmental protection workers and resources through contested territory and into emergency areas to protect the environment. They would also serve to increase awareness about obligations to protect the environment and would help to ensure the safety of environmental protection actors during armed conflict, as the role and mandate of these actors is explicitly accepted by stakeholders. Additionally, environmentarian corridors offer potential for conducting environmental protection activities on ecocentric grounds. The article concludes by advocating for stakeholders to employ the provisions and concepts articulated herein as a means to further promote and strengthen initiatives aimed at protecting the environment during armed conflict.

Given the increasing size and functions of United Nations (UN) peace operations (POs) and the fact that they often operate in contexts where natural resources are degraded, POs have repercussions on the environment. Yet, there is not much literature on their obligations regarding the protection of the environment in relation to armed conflicts. This article provides insights into the obligations of POs in relation to armed conflict. First, it highlights POs’ customary international environmental law obligations. Second, it delves into their environmental obligations under the UN's internal rules and the host State's laws. Third, it explores obligations that arise from their mandates. In each of these sections, the article highlights the relevance and application of these obligations in armed conflicts. The last section examines the obligations of POs to protect the natural environment under international humanitarian law.

The article seeks to raise awareness about the non-application of the norms of international humanitarian law (IHL) of international armed conflicts in situations of so-called internationalised armed conflicts – namely, when a non-state armed group (NSAG) that is engaged in an armed conflict against the territorial state enjoys a degree of support from another state. Debates in academic circles and international case law have focused largely on the appropriate test and threshold for establishing the relationship between the NSAG and the supporting state. Practice, however, shows that regardless of the legal test, the foreign state support to the NSAG in a (or an initially) non-international armed conflict is so politically charged that it leads to a complete non-application of the law of international armed conflict by the relevant actors. The article demonstrates its conceptual findings through four case studies: the armed conflicts in Donbas, Nagorno-Karabakh, Democratic Republic of the Congo, and Yemen. Regardless of strong indications of foreign state support to the NSAG in these armed conflicts, no relevant actors applied the IHL norms of international armed conflict. The article provides broader suggestions on the possible avenues for remedying the issue.

The Russian invasion of Ukraine has widely been seen as a failure of the international legal order, which could neither stop Russia from launching a war of aggression, nor prevent the perpetration of international crimes. In such a reading, great power politics have (once again) trumped international law. We argue instead that international law plays a crucial part in the conflict by providing a semantic infrastructure, which the opposing parties use to justify their actions, try to re-draw limits of permissible action and negotiate changing ‘red lines’ with the enemy. Drawing on the notion of lawfare, we show how the pragmatic (mis-)use of international law flexibly delineates boundaries and stabilizes expectations between adversaries even as they are contested in the current war. We focus on claims about self-determination and self-defence to justify the use of force; categorizations of combatants; and weapons transfers and the status of third states. That international law can be violated or reinterpreted to breaking point does not make it irrelevant. To the contrary, it recalls its important role as a language of conflict and compromise, beyond strictly legalist as well as dismissive realist views.

Both gender and the environment have traditionally been positioned at the periphery of international humanitarian law (IHL). In recent decades, there has been important progress in moving both concerns closer to its centre; to date, however, an understanding of the intersection of gender and the environment in the legal regulation of armed conflict remains largely underdeveloped. Nevertheless, as the present article documents, there are important similarities in strategies pursued to advance both gender and the environment from the periphery to the mainstream of IHL, namely: first, a focus on sources of IHL, in particular concretizing arguably limited specific treaty content with interpretive guidance and implementation frameworks; second, a conceptual critique of prevailing definitions of “harm” in IHL; and third, advancing, through close empirical documentation and household-level analysis of conflict's effects, understandings of harm that capture so-called “second-round” effects of conflict. Recognizing these important affinities between gender and environment work in IHL, this article draws on these insights to propose a typology of gendered environmental harm in conflict. The article concludes with proposals for enhancing the legal and operational capture under IHL of the gender–conflict–environment nexus.

Despite the thousands of pages written and words said about the Holocaust, I still am at a loss in trying to understand it. How a European people with a rich cultural tradition that produced some of the world's greatest composers, philosophers and poets could invent, enforce and docilely follow the first industrial genocide in human history remains, for me, an enigma. This essay focuses on the Jews, both numerically and ideologically the principal, but not the only, victims, the Roma being the other principal victims.
