This publication is a result of our long lasting efforts to foster collaboration and exchange between professors and scientists from the Faculty of Mechanical Engineering at the Ss. Cyril and Methodius University in Skopje, North Macedonia, and the School of Civil Engineering at the Aristotle University in Thessaloniki, Greece. Over the last years, there was a continuous effort for joint actions and initiatives on issues related to the management of the water resources that are shared between the two countries.

The transboundary surface water bodies of Vardar/Axios River, Dojran/Doirani Lake and Prespa Lake have undoubtful importance at national and regional levels fostering economic prosperity and development, social integrity and environmental protection. The management of these waters at basin scale is a step forward for achieving closer cross-border cooperation and for promoting sustainable development. The outputs of this publication demonstrate the current situation as well as the progress that has been conducted in the management of the transboundary waters of the two countries. Moreover, the provided material set the base for the Integrated Water Resources Management at basin scale and addresses further cooperation perspectives in the field of climate change adaptation and of Water-Energy-Food-Environment nexus.

The book contains both descriptive and informative sections that could be used for environmental educational purposes at both universities, but also to thoroughly depict our cooperation in different surroundings and backgrounds, as well as to shed light on future advancements.
