The quality of groundwater recharging the Guarani aquifer is threatened in some areas by rapid land-use changes, and locally by rapid urbanisation. Action was taken by the World Bank through a GEF-funded project on the ‘Sustainable Development & Environmental Protection of the Guarani Aquifer’, which included scientific studies, institutional provisions and transboundary groundwater management. This case study reinforces the lesson to ‘think globally but act locally’.
Steadily shrinking for decades due to unsustainable irrigation policies, the Aral Sea is under increasing pressure, making both allocation and availability major challenges. Action has been taken and the Basin Economic Allocation Model has been developed as a long-term decision support system to facilitate putting “value on water use”. This demonstrates that economic models can be applied to assess economic value maximization of different water uses.
Unsustainable irrigation policies during the Soviet era have had devastating consequences for the Aral Sea. With the collapse of USSR, the riparian states took action and entered into agreement on Cooperation in the Joint Use and Protection of Water Resources of Interstate Significance. Furthermore, the international community took action and much attention has been devoted to re-establish the Aral Sea ecosystem. This case illustrates the importance of engaging all key stakeholders.
In Central Asia, water is unevenly distributed with states positioned downstream being placed in a very unfavourable position. The situation is further complicated since the benefits from cooperation are highly asymmetrical. Despite the challenge, the states have taken action and entered into a regional agreement, which attracted the international donor community to engage further. This case illustrates how international initiatives can influence institutional arrangements in transboundary basins.
Dniester river basin is a transboundary basin shared by Moldova and Ukraine. Throughout the Soviet era, the water quality deteriorated severely. After the USSR was dissolved, a bilateral agreement was signed by Moldova and Ukraine on the joint use and protection of water resources. This cooperation framework is based on the contributions of network of local authorities. This case illustrates the importance of cooperation among all key stakeholders.
In the River Basin District of the CEE region, the countries are cooperating to develop transboundary management, using the International River Basin Commission as a platform. The aim is to address national IWRM priorities, strengthen cooperation with major stakeholders and initiate changes in policies and legislation. This case illustrates the difficulties to balance national priorities in a transboundary context.
The development of hydropower in the Mekong River basin can bring great economic opportunities for Laos. However, since this basin is shared with neighbouring countries, cooperation is crucial. Action was taken and the Agreement on the Cooperation for the Sustainable Development of the Mekong River Basin was signed to coordinate the use of these resources for economic development. For Laos, this has been crucial to their success in regards to the MDGs.
The Bodrog River Basin is exposed to severe flooding caused by jumbled urbanisation and low connectivity between land (agriculture and forestry), urban and water planning. Management is made more complex by the transboundary nature of the basin. A project was, however initiated to strengthen cooperative management and to mitigate consequences of floods through achieving consistent and holistic management of flood risk in three basin countries. This case illustrates the importance of transboundary flood management.
