Abstract: Adapting to the challenges of global climate change requires a new way of thinking in all areas of life. The use of renewable energy sources can provide an opportunity to reverse the negative spatial processes that have occurred in the past, often as a result of careless human interventions, and to create a healthy ecosystem service. There are many uses for a site, and coordinating them requires careful development and sustainable land use planning.
The case study of the Rétköz lake in northeastern Hungary illustrates a habitat rehabilitation project where several human uses have been coordinated in the conservation and restoration of the natural environment. As a consequence of climate change, the good condition of the habitat can now only be maintained artificially, with the use of renewable energy sources playing a key role. The rehabilitation and sustainable management of the Rétköz lake is a model for resolving land use conflicts and providing a rich ecosystem service powered by renewables. The pilot project has produced positive results that were not expected, which could create an opportunity to reform the water management of the Tisza Valley for multiple purposes. The welcome increase in renewable energy-based energy production technologies could provide a good opportunity for sustainable management.
The hypothesis of the long-term research is that the water system of the Tisza Valley can be adapted to the expanded needs, partly by partial restoration of the former aquatic ecosystem and by modification of the existing infrastructure. The energy needs of the system can be met by locally available renewable energy sources, providing a sustainable multifunctional ecosystem service for the environment, economy and society. The aim of this research is to prove the above hypothesis.
