This article investigates the effects that attacks during armed conflict which damage water and wastewater services have on the outbreak and transmission of infectious disease. It employs a lens of uncertainty to assess the level of knowledge about the reverberations along this consequential chain and to discuss the relevance to military planning and targeting processes, and to the laws of armed conflict. It draws on data in policy reports and research from a wide variety of contexts, and evidence from protracted armed conflicts in Iraq, Yemen and Gaza. The review finds a strong base of evidence of the impact of attacks on water and wastewater services, and a high level of confidence in information about the transmission of infectious disease. One clear risk identified is when people are exposed to water supplies which are contaminated by untreated wastewater. Obtaining a similar level of confidence about the cause and effect along the full consequential chain is challenged by numerous compounding variables, though there are a number of patterns related to the duration of the armed conflict within which the attacks occur. As the conflict protracts, both the risk of the spread of infectious disease and the evidence base for gauging the reverberating effects becomes stronger, for example. The article concludes that the reverberating effects of damage from an attack can be foreseen in some contexts and can be expected to become more foreseeable over time. The analysis suggests that the most pragmatic path for military institutions and those involved in targeting operations to take this knowledge into account is through a “precautionary approach” which assumes the existence of the reverberating effects, and works them in to the standard information-gathering and planning processes.

Protracted conflicts are a major source of human suffering and can cause long-term displacement and development reversals. Although protracted conflicts can take many forms, they are generally characterized by their longevity, intractability and mutability. Authorities involved in situations of protracted conflict face complex challenges, particularly when it comes to ensuring that international humanitarian law (IHL) is respected by their armed forces.

The government of the Philippines has been involved in multiple non-international armed conflicts against insurgent groups for more than fifty years. In this interview, Lieutenant-Colonel Joven Capitulo, who works to implement the policies, activities and programmes of the Philippine Department of National Defense and Philippine Department of Defense initiatives on national legislation pertaining to compliance with IHL, shares the perspective of a State dealing with several protracted situations of non-international armed conflict. He tells the Review about some of the IHL considerations involved when a military is engaged in counter-insurgency on its own territory over a period of decades.

Legal controversies and disagreements have arisen about the timing and duration of numerous contemporary armed conflicts, not least regarding how to discern precisely when those conflicts began and when they ended (if indeed they have ended). The existence of several long-running conflicts – some stretching across decades – and the corresponding suffering that they entail accentuate the stakes of these debates. To help shed light on some select aspects of the duration of contemporary wars, this article analyzes two sets of legal issues: first, the notion of “protracted armed conflict” as formulated in a war-crimes-related provision of the Rome Statute of the International Criminal Court, and second, the rules, principles and standards laid down in international humanitarian law and international criminal law pertaining to when armed conflicts have come to an end. The upshot of the analysis is that under existing international law, there is no general category of “protracted armed conflict”; that the question of whether to pursue such a category raises numerous challenges; and that several dimensions of the law concerning the end of armed conflict are unsettled.

Ever since the first quarter of the nineteenth century, Colombia has shifted from one war to the next, be it the War of Independence, the fierce confrontations between liberal and conservative parties or the countless conflicts among guerrillas, paramilitary groups and the State. These wars have brought along a unique contribution to the development of international humanitarian law (IHL). The purpose of this article is to explore the myriad of ways in which Colombia has implemented (and at times made progress on) IHL rules, and to analyze how different conflicts have led the country to explore issues such as the protection of minors, the meaning of the principle of precaution, the compensation of armed conflict victims and the creation of some rather sophisticated transitional justice mechanisms.
