Factors Affecting Transboundary Water Disputes: Nile, Indus, and Euphrates–Tigris River Basins

Transboundary water disputes arise as nations compete over shared water resources, exacerbated by climate change, socio-economic inequalities, and geopolitical tensions. These disputes, prominent in river basins like the Nile, Euphrates–Tigris, and Indus, threaten regional stability, water security, and ecological sustainability. This study investigates the drivers of such conflicts, evaluates the role of historical treaties, and examines the socio-economic and political dynamics, including hydro-hegemony and power imbalances, that influence governance. The research addresses the two following key questions: what factors drive transboundary water disputes, and what lessons from past conflicts and cooperation can guide future governance frameworks? Using a descriptive approach, the study critically analyses the literature and case studies to identify actionable insights. Specific objectives include analyzing drivers of conflict, assessing treaty efficacy, and deriving sustainable water-sharing strategies. Findings reveal that climate variability, population growth, and outdated agreements intensify challenges. In the Nile River Basin, Ethiopia’s Grand Ethiopian Renaissance Dam (GERD) strains relations, while in the Indus Basin, the outdated Indus Waters Treaty struggles to address modern demands. Similarly, unilateral actions in the Euphrates–Tigris River Basin (ETRB) exacerbate socio-political instability. The study underscores the importance of inclusive governance, equitable treaties, and integrated strategies, such as integrated water resources management and climate adaptation, to balance ecological, socio-economic, and geopolitical priorities. Linking these efforts to the Sustainable Development Goals highlights their potential to transform conflict into opportunities for regional stability and shared prosperity.
