Working Together for Resilience and Economic Growth in the Sava and Drina Corridors

The World Bank developed a report identifying challenges facing the Sava and Drina Rivers Corridors in Croatia, Slovenia, Bosnia and Herzegovina, Montenegro and Serbia, and outlined recommendations to improve natural disaster resilience, transboundary water cooperation and economic growth. It encourages continued regional Bank engagement through technical assistance and projects such as the Sava and Drina Rivers Corridors Integrated Development Program.


The report outlines challenges facing the Sava and Drina River Corridors. Among them are the following:

  • There is limited cooperation and coordination among the riparian countries along the Sava and Drina Rivers, thus impeding the development of the corridors as shared economic assets and hindering job creation and economic growth.

  • The Sava and Drina Rivers are susceptible to dry spells and mass flooding, both of which occurred between 2010-2014, and are further exacerbated by poorly maintained and outdated hydraulic infrastructures.

  • Large hydropower projects are often postponed or cancelled even as electricity consumption is estimated to increase significantly, thus resulting in high demand and decreasing generation capacity.

  • The Sava River has bottlenecks that prevent medium or large cargo ships from traveling on the river, thus resulting in decreased trade, lower investments in ports and a greater reliance on costly and less environmentally friendly alternatives such as roads and rails for shipping.


The World Bank has worked with riparian countries in the Sava and Drina corridors since 1989 on initiatives including a regional partnership on water resources and on irrigation, energy security and flood protection. Regional priorities include fostering economic growth and job creation, regional connectivity, facilitating trade and increasing resilience against disasters and climate-related risks. Over the past 13 years, this has been manifested in the development of the Climate Adaptation Plan for the Sava River Basin and the Investment Priority Framework Project in the Drina River Basin, while ongoing activities at the regional level include the Drina River Basin Management Project and the Bosnia and Herzegovina Drina Floods Protection project. Moreover, the World Bank has also acquired experience with regional water resources projects in the Western Balkans outside the Sava River Basin, notably with the Global Environment Facility (GEF) funded Lake Shkoder Management Project (involving Montenegro and Albania) and the Neretva-Trebisnjica River Basin Management Project (involving Republika Srpska (RS), Federation of Bosnia and Herzegovina, and Croatia).


The report produced the following findings:

  • The Sava basin is an important source of job creation in the region, as it generates 20.5 percent of employment in Serbia, 35.3 percent employment in Croatia and 54.4 percent employment in Slovenia.

  • The Drina corridor has significant potential for hydropower generation, food production and tourism development. 

  • Increasing cooperation between riparian countries on water management issues, including integrated investment in and management of the corridor, could result in significant economic benefits for all countries across numerous sectors.

  • River cruising on the Sava could generate ample untapped economic growth.

  • Interventions along the Sava River like dredging and river training can help revitalize and protect floodplains, wetlands and the development of new energy infrastructure – results which could thus collectively boost eco-tourism and enable investments in hydropower and irrigated agriculture.

  • Drina corridor water resource planning must integrate hydropower reservoir operations, flood and drought management, tourism development, agriculture and climate change adaptation to increase protection against flood and climate-related risks.

The report led to the development of the Sava and Drina Rivers Corridors Integrated Development Program using a longer-term approach to be implemented in phases. The World Bank-financed program aims to improve the management and development of the Sava and Drina River Corridors through activities such as financing the construction and rehabilitation of dykes, improving watershed management in the Lim and Grncar River basins, and facilitating regional studies and dialogues, among other activities to mitigate flood risks, increase transboundary cooperation and promote the sustainable use of natural resources.

Bank Group Contribution

The cost of developing the report was $212,895 – of which $83,115 was contributed by the Bank’s budget and $129,780 was contributed by the Global Water Security & Sanitation Partnership (GWSP). The International Bank for Reconstruction and Development is providing a loan of EUR 123.2 million, which was approved in 2020, for the Sava and Drina Rivers Corridors Integrated Development Program.


The World Bank has worked with the International Sava River Basin Commission (ISRBC) - which supports the Sava and Drina countries in strengthening their cooperation to obtain investment benefits – on the preparation of the 1st Sava River Basin Management Plan. The Bank also worked with the ISRBC, which includes Bosnia and Herzegovina, Croatia, Serbia and Slovenia, to develop the first Flood Risk Management Plan for the Sava River Basin and consulted with other donors, including the European Commission. In addition, the Bank reached out to the Western Balkan Investment Framework and the Global Environment Facility.

Moving Forward 

Next steps in enhancing resilience and regional cooperation in the Sava and Drina corridors will include World Bank support, including through efforts like the Sava and Drina Rivers Corridors Integrated Development program, to strengthen flood protection, improve the navigability of the Sava River and promote ecotourism, among other interventions, to thus convert the vision outlined in the report into concrete outcomes.


This study was targeted at helping Serbia, Bosnia and Herzegovina, Montenegro, Croatia and Slovenia improve natural disaster resilience, transboundary water cooperation and economic growth. In working closely with the ISRBC, it has helped further the Commission’s goal of enhancing cooperation among Sava and Drina countries to capture benefits from investments. It has also helped contribute to European regional priorities of improving energy and transport infrastructure. Any investments or follow up action based on the findings and recommendations of the study would benefit the people and economy of the countries along the corridor.
