Although international humanitarian law has as its aim the limitation of the effects of armed conflict, it does not include a full definition of those situations which fall within its material field of application. While it is true that the relevant conventions refer to various types of armed conflict and therefore afford a glimpse of the legal outlines of this multifaceted concept, these instruments do not propose criteria that are precise enough to determine the content of those categories unequivocally. A certain amount of clarity is nonetheless needed. In fact, depending on how the situations are legally defined, the rules that apply vary from one case to the next. By proposing a typology of armed conflicts from the perspective of international humanitarian law, this article seeks to show how the different categories of armed conflict anticipated by that legal regime can be interpreted in the light of recent developments in international legal practice. It also reviews some actual situations whose categorization under existing legal concepts has been debated.

The current legal regime relative to occupation is no longer based solely on the contributions made by customary law and treaty-based law as set forth in the law of The Hague and the law of Geneva. It has undergone a thorough change with the progressive recognition of the applicability of human rights law to the situations which it governs, and their complementarity has been highlighted on several occasions. The question of the interrelation of international humanitarian law and human rights is not resolved merely by analysing their respective areas of application. The author examines the issue at the level of their individual rules. He considers whether the rules of international humanitarian law are confirmed, complemented, relativized or even contradicted by those deriving from human rights. The analysis focuses more particularly on the interrelation of the law of occupation and economic, social and cultural rights by concentrating on the promotion of adequate standards of living (right to food, right to health) and respect for property.
