This article examines the historical background and the state of the art of transboundary water management in the Central Asian region, which includes the republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, on one hand, and the Iberian Peninsula, which consists of the Kingdom of Spain and the Republic of Portugal, on the other hand. These distances from each other regions are studied for the reason that both of them are located in arid landscapes and further climate change is posing grave challenges to transboundary water security. By highlighting the differences and similarities in the water management practices of Central Asia and the Iberian Peninsula, this article employs a path-dependence approach to shed light on new perspectives on good water management. As a result of identified opportunities, the Central Asian states could enhance their policy in the water management system and adopt new measures based on positive foreign experience.
