TRANSBOUNDARY RIVERS OF CENTRAL ASIA: POLITICAL-ECOLOGICAL CONFLICTS AND GOVERNANCE CHALLENGES IN THE AMU DARYA AND SYR DARYA BASINS

Abstract

The Amu Darya and Syr Darya rivers constitute the hydrological lifelines of Central Asia, collectively draining a basin of approximately 1.9 million km² across six sovereign states and sustaining the livelihoods of more than 80 million people. Yet these rivers are also the most politically contested natural resources in the post-Soviet region. The collapse of the Soviet Union in 1991 transformed previously administrative internal boundaries into international frontiers, converting long-established water-sharing arrangements into interstate disputes without a coherent multilateral governance framework to replace them. This paper presents a systematic political-ecological analysis of transboundary water conflicts in the Amu Darya and Syr Darya basins, examining the structural asymmetries between upstream hydropower-prioritizing states (Kyrgyzstan, Tajikistan) and downstream irrigation-dependent states (Uzbekistan, Kazakhstan, Turkmenistan). Drawing on a corpus of 98 peer-reviewed studies, 14 intergovernmental treaty texts, hydrological time-series data spanning 1960–2023, and 62 expert interviews conducted between 2018 and 2023, we analyze four principal axes of conflict: seasonal flow regulation and the hydropower-irrigation trade-off; water allocation disputes under conditions of increasing scarcity; the political economy of proposed large dam infrastructure (Rogun and Kambarata); and the institutional inadequacies of the existing interstate governance architecture. Our results demonstrate that mean annual river discharge reaching downstream territories has declined by 23–38% since 1990, that water demand exceeds sustainable supply across 70% of the basin during peak irrigation season, and that the lack of a binding multilateral treaty with enforcement mechanisms constitutes the primary structural impediment to resolution. We propose a six-pillar governance reform framework grounded in principles of equitable sharing, ecological sustainability, climate resilience, and phased economic compensation among riparian states.
