International Legal Regulation of Transboundary Waters of Central Asia

Abstract

This study examines the legal regulation of transboundary waters in Central Asia, focusing on the Amu Darya
and Syr Darya basins. The objective is to assess how international and regional legal frameworks,
institutional mechanisms and procedural tools—including transboundary environmental and social impact
assessment (ESIA), annual operating protocols and compensation mechanisms—support cooperative,
sustainable basin management. The methods combine normative legal analysis of international conventions
and basin treaties, a comparative case study approach (Rogun and Toktogul), a documentary review of ESIAs
and reports of basin organization, and a synthesis of secondary literature. The key findings indicate that the
existing multi-layered architecture provides essential procedures for cooperation but leaves practical gaps in
transparent compensation formulas, transboundary groundwater governance and sustainable financing for
shared monitoring. The Rogun case highlights the need for early, jointly agreed ESIA terms, enforceable
mitigation and multi-year contractual arrangements. The Toktogul case demonstrates the operational
necessity of formulaic annual protocols, interoperable real-time data exchange and timely compensation
mechanisms. The conclusions stress that harmonizing national law with basin agreements, establishing
neutral technical secretariats, implementing interoperable monitoring and verification systems, and creating
formal compensation facilities increase predictability, reduce transaction costs and strengthen resilient and
mutually beneficial management of transboundary waters in the region.
