UN Water Convention: Transboundary Water Cooperation

Introduction

The Convention on the Protection and Use of Transboundary Watercourses and International Lakes, commonly known as the UN Water Convention, is an international legal instrument designed to promote the sustainable management of shared water resources.

It was adopted in 1992 under the framework of the United Nations Economic Commission for Europe (UNECE).

Objectives

  • Prevent, control, and reduce transboundary impacts.

  • Promote reasonable and equitable use of shared waters.

  • Encourage cooperation between countries sharing rivers, lakes, and aquifers.

  • Protect aquatic ecosystems.

  • Improve water quality and prevent pollution.

  • Strengthen joint monitoring, information exchange, and institutional cooperation.

Major principles

1. Prevention of transboundary harm

Countries should take appropriate measures to prevent, control, and reduce significant adverse effects on other countries arising from transboundary water activities.

2. Equitable and reasonable utilisation

Shared water resources should be used in a fair and reasonable manner, taking relevant geographical, environmental, social, and economic factors into account.

3. Cooperation

Countries sharing water resources are encouraged to cooperate through agreements, joint bodies, consultations, and information exchange.

4. Ecosystem protection

Water management should consider ecological health and the long-term sustainability of aquatic ecosystems.

Membership and international significance

  • The convention was adopted in Helsinki in 1992.

  • It entered into force in 1996.

  • Initially developed as a regional instrument for the UNECE region, it became open to all UN Member States in 2016.

  • It complements other international frameworks concerned with freshwater management and sustainable development.

Difference from the UN Watercourses Convention

The 1997 UN Convention on the Law of the Non-Navigational Uses of International Watercourses is a separate international legal instrument. It focuses on the use, protection, and management of international watercourses for purposes other than navigation.
