The Criş/Körös Rivers' Valleys

Sárkány-Kiss, A. & Hamar, J. (eds): The Criş/Körös River Valley. A study of the geography, hydrobiology and  ecology of the river system and its environment. Szolnok - Szeged - Târgu Mureş, 1997.




In November 1993, 42 European countries have agreed in Maastricht, the Netherlands, that their nature conservation administrative bodies will in close co-operation create a transboundary European Ecological Network (EECONET). They have recognised that it is crucially important for the future of our overcrowded Europe to restore habitats and to conserve the chains of both designated and non-designated but still valuable sites that have preserved their natural or near-natural conditions.

River Corridors, i.e. the chains of riparian habitats, are of outstanding importance in the Carpathian Basin from the aspect of wise use technologies and the biological diversity. It certainly requires particular responsibility and a good sense of diplomacy to organise scientific research, nature conservation or regional development programmes that involve several countries, nevertheless, the protection of riparian ecosystems cannot be successful on some arbitrarily selected part of a catchment area, and is impossible without the partnership of local governments, farmers, authorities, institutes and all other stakeholders.

The nationalities of the Carpathian Basin live in a remarkably variegated and biogeographically diverse area. Living in a single basin, however, also incurs numerous common tasks and responsibilities for the governments in the fields of environment protection and nature conservation. It is a wonderful experience, when non-governmental organisations, research and education institutes join their forces to make a complex: geographical, biological, hydrobiological and ecological inventory on a multinational river and its flood plains, following a unified and internationally supported concept and methodology. This has happened in the case of the Körös/Criş rivers. Together with some colleagues, I am fortunate enough to be able to actively participate in the establishment of the Hungarian Ecological Network; moreover, we had the honour to take part in the elaboration of the EECONET concept. Our team has the opportunity to contribute in effect to the conservation and survival of valuable wetlands such as riparian ecosystems by legislative work and the application of laws, research and, habitat restoration programmes, site protection and the establishment of national parks. We, think that the close collaboration of the Romanian and Hungarían nature conservation bodies is of utmost importance, between governments, NGO's and researchers alike.

After similar publication on the Maros/Mureş Valley this is the second volume of the scientific summary of an outstandingly valuable and complex Hungarian-Romanian project. The Hungarian Ministry of Environment and Regional Policy has found the publication of this remarkably successful project worthy of support, especially because of the most convincing results in the Upper Tisza region. Initiated and organised by non-governmental organisations, namely the Tisza Klub (Szolnok. Hungary) under the leadership of József Hamar and Andrei Sárkány-Kiss from the Liga Pro Europa (Tărgu Mureş, Romania), the project also received indispensable support from numerous universities, research institutes, environmental and nature conservation administrative bodies and the students of the Babeş-Bolyai University.

I hope this project and publication will be a good example for many people across Europe for a delightful co-operation between two neighbouring countries. I am convinced that the database here published will be widely and successfully used, by governmental and non-governmental organisations and scientific workshops alike, as we work together to fulfil our common tasks. I am also convinced that we will not have to wait long for the continuation of this proiect and for its international support...
