Abstract

Management of transboundary waters is increasingly becoming more challenging, particularly within a context of complex social and environmental changes. Population growth, often concentrated in the developing world, will increase pressure on already scarce resources. Climate change is likely to exacerbate these pressures, making it more difficult to manage water across boundaries (4). The 6th IPCC assessment and the 2023 IPCC synthesis report recognize transboundary risks across the food, energy, and water sectors, requiring climate-informed transboundary management.

Transboundary water resources, such as rivers, lakes, and aquifers, often traverse political boundaries, requiring cooperation among neighboring countries for sustainable and equitable management. The effects of climate change, including altered precipitation patterns, rising temperatures, and more frequent extreme weather events, pose significant threats to the availability and reliability of these shared water sources. Recognizing the interconnectedness of climate change and transboundary water management is essential for developing resilient and adaptive strategies.

Climate-informed transboundary water management is a critical aspect of addressing the challenges posed by climate change on shared water resources. As the impacts of climate change become more pronounced, the need for adaptive and collaborative approaches in managing transboundary water sources becomes increasingly evident. This article explores the key components, challenges, and strategies associated with climate-informed transboundary water management.

The aim of this article  is to identify  need  establishing cooperative transboundary mechanisms to effectively adapt water management to climate change. Furthermore, this article  will also address complex legal difficulties  that existing transboundary water institutions face when attempting to adapt existing mechanisms to function in a changing climate.

Introduction

The world's water resources are facing unprecedented pressures from population growth and economic development. Estimates indicate that, with current practices, the world will face a 40 percent shortfall between forecast demand and available supply of water by 2030. Climate change is worsening the situation, making water availability more unpredictable and increasing the frequency and intensity of floods and drought
