Miókovics, E., Bódis, J. & Molnár, Zs.: Analysis of landscape change in the Nagyberek (Somogy, Hungary) with the DPSIR Framework. Abstract: We need complex thinking to manage habitats and conserve landscape values. We present the landscape changes between 1900 and 2013 of the Nagyberek, a huge, former marshy area along the south bank of Lake Balaton, with the help of the DPSIR Framework. We analysed the causal relations of driving forces, which induce landscape changes, and the change of habitat states from the nature conservation point of view. Our results show that the introduction of large-scale farming during the 1950-80s was the main driving force. The changes caused by the disruption of the natural water balance were too drastic and the ecosystem could not adapt to the new circumstances. The rapid changes also altered the self-identity of inhabitants and their relationship with the landscape. Landscape changes were analysed from the conservation biologist point of view. Accordingly the responses of the DPSIR Framework were selected from those laws and programmes which concern nationally and internationally important habitats. We argue that the DPSIR Framework can be used successfully to study the impact of pressures to analyse habitat and landscape changes in a complex way. Keywords: land use, nature-agriculture interface, landscape history, wetlands. Introduction According to the European Landscape Convention (2000) the landscape “means an area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors”. The study of past changes and processes is needed to understand the functioning of a landscape. The effects of land use on landscape changes should be studied from the point of view of nature and humans as well. This thinking is necessary to ensure the good practice for conservation (Biró 2006, Folke 2004). The main factor of landscape changes is land use, which alters the landscape fundamentally. The transformation of traditional landscape management fundamentally changes the natural and the social environment. Several models can be used in landscape change studies to investigate the spatial changes in land use, such as GIS based models, e.g. CLUE (Veldkamp & Fresco 1996, Verbürg et al. 2002). Landscape change research shows increasing interest in the driving forces which induce the changes (Bürgi et al. 2004). Comprehensive analyses, for example in landscape planning, seek real solutions to protect and maintain the landscape.
