Transboundary water management: a multilevel progression in the Prespa basin

Main concepts - an overview

Over the second half of the 20th century, the concept of transboundary water management evolved to varying degrees globally. The main principles of international water law, including transboundary co-operation on certain aspects, were introduced in the early 1990s. The EU Water legislation, adopted ten years later, provided a robust policy framework for Europe, as it applies to both EU states and EU candidate countries, which are gradually revising their legal and institutional frameworks towards accession.  

This lecture will deal with the topic of transboundary water co-operation in Europe presenting the case of the Prespa basin as a paradigm. The presentation will answer the following questions:


-       Why should countries sharing freshwater resources pursue co-operation?

-       What are the EU water legislation requirements for international river basins?

-       Which governance schemes are encountered in the shared river basins in Europe?

-       How has transboundary water co-operation evolved in the countries of the Prespa basin and what are the lessons that have been learned? 


Transboundary co-operation in shared river basins in Europe

More than half of the available freshwater on earth is located in transboundary river basins, in which half of the world’s population lives and depends on these waters. When two or more countries share water resources, such as a lake, river or groundwater, each is very susceptible to the practices of the other/s, as water use in one country inevitably affects the condition of the resources in a neighbouring country. It is only through co-operation that countries sharing a river basin may exchange information, get the bigger picture of the state of their common water resources and the challenges that exist, and work out solutions for their optimum management to their mutual benefit.

In 2000, the EU Water Framework Directive introduced a holistic approach, adopting the river basin management concept, which calls for the management of water resources within their natural hydrological units. For aquatic ecosystems which cross national borders this necessitates the co-operation of states, and planning and management at a transboundary level.     

Prespa is one of 105 international river basins identified in Europe, which vary in terms of size, conditions, challenges and the degree of international co-ordination. The most advanced European examples include basins with a formal agreement, international co-ordinating mechanisms in operation and joint river basin management plans in place. This is the case for the most complex shared basins, such as the basin of the Danube River, which lies across 19 countries, and the Rhine, which includes nine countries.



The Prespa basin at a glance

The Prespa basin is comprised of two interconnected lakes and their surrounding mountain ranges, which extend across the borders of three countries - Albania, Greece and North Macedonia. It is an inhabited basin and a globally recognised biodiversity hotspot, because of its exceptional wildlife and ecological significance. For this very reason, in all three countries parts of the basin have been designated wetlands of international importance under the Ramsar Convention and protected areas at a national level.

Amongst the oldest lakes in Europe, Lesser and Great Prespa, together with Lake Ohrid (North Macedonia/Albania), and the now drained Lake Maliq (Albania), once formed the ancient European sister lakes, the Dessaretes lake group. Prespa has no surface outflow and the waters of its basin drain into Lake Ohrid through underground channels, before flowing into the Black Drin River, which joins the Drin river basin that eventually discharges into the Adriatic Sea.

The vast majority of the remarkable habitats and species in Prespa are dependent on the two lakes and the several watercourses flowing in the region. However, Prespa freshwater resources are being degraded, due to unsustainable human practices across the basin. Intensive agriculture and inadequately treated domestic and industrial effluents are the main drivers of water quality deterioration. Obsolete irrigation networks and the unsustainable abstraction of water impact water quantity, which further intensifies the water quality challenges. The above, in combination with anticipated climate change effects in the region, may have detrimental effects on the vulnerable ecosystems and therefore it is critical to address them. Unlike the three states Prespa stretches across, the water of the two lakes has no borders and keeping it well maintained is a shared necessity and responsibility. 

The evolution of water collaboration in Prespa

Trilateral co-operation was initiated in 2000, with the joint Prime Ministerial ‘Declaration of the Prespa Park for the Environmental Protection and Sustainable Development of the Prespa Lakes and their Surroundings’. The first transboundary protected area to be established in South Eastern Europe, through the set-up of interim institutional structures by the three states, the Prespa Park provided a forum for interstate dialogue, information exchange, joint research and projects, the cultivation of trust and co-ordination of action between decision makers, key local stakeholders, international organisations and the donor community. Over the years of cross-border co-operation the foundations in the field of transboundary water governance were laid, with the parties reaching consensus on the priority of co-operation on the basis of the river basin management principles provided for in the EU water legislation.

Ten years later, in 2010, the states upgraded their commitment to co-operate by signing a binding ‘International Agreement on the Protection and Sustainable Development of the Prespa Park Area’, to which the European Commission was also a party. Integrated river basin management was placed at the core of this agreement, which provides for a permanent expert group on water management as part of the institutional structures that were foreseen for interstate co-operation.

Over the past two decades, progress has been achieved towards addressing the main challenges and improving water governance across the region. This has been interlinked with the gradual deepening and flourishing of cross-border collaboration between non-state actors. NGOs have played a key role in supporting transboundary water governance, by identifying knowledge gaps, building stakeholder capacity, advocating for favourable water management reforms and policies, raising local awareness and shifting unsustainable perceptions and practices. The prevention of harmful projects, such as the reactivation of the River Devolli diversion works, that had caused significant environmental and social damage to Lesser Prespa Lake, was made possible due to joint scientific and advocacy work across the borders. Co-ordination of action at the transboundary level is imperative, in order to control the most crucial threat to the Prespa lakes – eutrophication – and non-state actors are working for the harmonisation of water monitoring methods, which will provide better scientific knowledge and foster sound water policy decisions.

The effective governance of shared water resources is a challenging process, involving multiple factors. The experience and knowledge gained over the years of transboundary co-operation in Prespa demonstrate that sharing information and long-term joint scientific understanding are required for the effective planning of actions that will address ecosystem and human needs across international basins. Networking and synergies between local actors are crucial, and NGOs can play a catalytic role in promoting good water governance. Indeed, the Prespa actors have moved well ahead in the continuum of progress, by advancing dialogue, building trust and consensus, reinforcing synergies and carrying out joint actions. Nevertheless, it is the high-level commitment and institutional framework that will eventually allow for effective water management in international waters. Securing these is a challenging task, which requires substantial time and funding in order to overcome short-term political cycles and gain significant reform.
