International law and water

Freshwater is an essential natural resource whose many uses leave their mark on social, economic, political and cultural relations, both internationally and nationally. Access to this resource, and its management and protection, are a source of concern. Challenges such as water scarcity, pollution and environmental degradation, and the use of water as a weapon of war, call for the mobilization of international law.

The Chair's teaching focuses on the contribution of international law to the regulation of the various uses of water. Whether as borders between states or as routes for navigation and trade, rivers were very early on the focus of international law. International water law has subsequently developed in line with new uses. In this context, the objectives of the United Nations' Agenda for Sustainable Development (2030) recall the need to ensure access to water for all.

International law also plays an important role in preventing and settling water-related disputes, through mechanisms of a diplomatic or judicial nature. When armed conflicts arise, water can be both a target and a weapon. International law provides rules to protect this resource. However, the question arises as to how these rules can be strengthened, and how crimes committed can be punished.

The course will benefit from the input of specialists from different parts of the world. These specialists will provide a theoretical and practical perspective on current issues.
