Introduction

Many transboundary water basins around the world are facing climate-related challenges that will intensify in the decades to come. Successful adaptation will be an important precondition for ensuring sustainable development and political stability in these basins. At the same time, stability and cooperation are preconditions for successful adaptation. How can riparians best achieve these interrelated objectives? And with the international community seeking to support both processes, how can water and climate diplomacy strengthen each other?

This report* outlines key water governance instruments that support climate change adaptation in trans- boundary basins. An increasing number of river basins use such instruments, for example data and information sharing mechanisms or flexible water treaties, to address the impacts of climate change and build adaptive capacities. Yet, this report also shows that in many basins such instruments are not employed at all or only to a limited extent. In identifying existing shortcomings, the report asks how such weaknesses could potentially be ameliorated by climate policy instruments. 

This report further illustrates that the impacts of climate change are not only a threat to socio-economic development but can also contribute to (re-)emerging conflicts in transboundary river basins. It is therefore important to build capacities to adapt to climate change and increase resilience in internationally shared water basins to strengthen environmental protection, economic and social development as well as regional political stability.

Recommendations

Climate policy provides a number of tools, including vulnerability assessments and adaptation planning, that could further strengthen adaptation in transboundary basins, especially if they were applied at basin scale. Moreover, international climate finance can provide much-needed additional resources for adaptation activities. If well designed, these tools can also generate co-benefits by building trust between riparians over shared challenges and identifying mutually beneficial opportunities for managing change and uncertainty. However, achieving such synergies needs mutual cognizance and proactive engagement of the water and climate communities, in order to harness existing experiences and to transfer them to the transboundary level.

With this objective in mind, and drawing on empirical examples from transboundary river basins from around the world, the report concludes with a number of recommendations for national, transboundary and international actors. In response to the inter-related challenges of successfully managing environ- mental, socio-economic, and political change, they should:

  • promote and support the incorporation of basin-wide, transboundary thinking in national adaptation planning and, simultaneously, the integration of climate change adaptation policies into existing and newly established basin institutions;

  • support activities to strengthen linkages between regional and national river basin governance through the establishment of specific organizational units or standardized communication procedures;

  • promote transboundary and, where possible, basin-wide data and information sharing, including specific climate change activities (e.g. vulnerability assessments), and facilitate their simultaneous use for confidence-building and ideally the elaboration of joint adaptation responses;

  • ensure sufficient funding for the core tasks of river basin institutions through reliable membership contributions and facilitate access to bilateral and multilateral climate funding to cover additional costs of adaptation;

  • support riparian states in establishing new basin institutions and strengthening existing ones by ensuring the integration of governance mechanisms that help dealing with change (such as flexibility mechanisms, dispute resolution provisions or standards for transboundary environmental impact assessments). 

Further potential entry points for closer and more integrated cooperation, at the national, regional and international level, are provided on pages 25 and 26 of the report.
