Purpose of research: Applied research
Pond farming areas provide a variety of services and more than mere fish production: fish farming ponds have positive effects on microclimate and regional water balance. They do not only serve as valuable habitats for many species, but also provide jobs and a space for recreation and tourism. Exploring possibilities on how this ecologically important cultural landscape with its high biodiversity can be protected is the main focus of the “TeichLausitz” project. The Upper and Lower Lusatian pond farming area covers parts of Brandenburg, Saxony and the Polish Lower Silesia representing the largest pond landscape in Central Europe. Its man-made fish farming ponds have been defining elements of the region’s landscape and culture for more than 750 years. Large parts of this area have been designated as an UNESCO biosphere reserve recognizing its high protection value. Regional fish production, however, is undergoing drastic structural changes: high fish losses due to predators, which in turn are protected under nature conservation or species protection law, water shortage due to climatic change, declines in consumer demand and low prices, environmental regulations, investment backlogs and a lack of successors are challenging the aquaculture enterprises of the region. Many of them have given up their businesses due to the economic pressures. While the primary focus on food supply is decreasing, there is an increasing emphasis on the many positive side effects of ponds – the so-called ecosystem services. These are, for example, nutrient fixation, water retention, cultural identity and providing space for recreation and tourism. A continuous management of the ponds can be seen as a prerequisite for these services. This is why the progressive number of farm closures also endangers the persistence of these cultural landscapes. Thus, from a societal perspective, the conservation of pond landscapes is of tremendous importance. The “TeichLausitz” project therefore aims to reveal the essential connections between pond management profitability and biodiversity conservation. In addition, the project will examine the negative consequences of further declines of carp farming enterprises for nature and society. The results will enable the analysis of possibilities to remunerate ecosystem services provided by pond farming areas in order to develop scenarios for the conservation of carp pond farming in Lusatia. For this purpose, the pond management of Brandenburg and Saxony is analyzed from ecological, economic and societal perspectives using a transdisciplinary approach. The different administrative and political frameworks of the two federal states allow for an analysis of the effects of existing structures, instruments and measures on the conservation and protection of biodiversity on the one hand, and on the profitability of regional carp farms on the other hand. Such an analysis of the current situation is the basis for the development of effective governance structures and innovative policy instruments to promote sustainable management of carp ponds. This may help to conserve the pond landscapes with their biodiversity and their ecosystem services in the long term.
