Resumo: Understanding changes in land use and land cover (LULC) is a prerequisite for the sustainable management of ecosystems, with implications for regulatory policy. In this study, we use a hierarchical approach to quantify long-term changes in LULC in the catchment of the largest Central-European shallow lake (Lake Balaton, Hungary). We evaluate changes over three centuries at the catchment and different spatial levels of the shoreline. Within this framework, we develop a methodology suitable for analysing land use transformations in the shoreline zone, typically affected by LULC changes stemming from mass tourism. Our findings indicate that LULC transformations at the catchment level were relatively minor compared to those observed along the shoreline, where urbanization driven by mass tourism emerged as a drivers of LULC changes. The dynamics of urbanization closely mirrored socio-political shifts and exhibited a strong dependence on distance from the shore. Temporal trajectories of LULC changes revealed that the most significant alterations occurred within the 0–500 m and 500–1000 m shoreline distance zones during the socialist era when the lake served as a focal point for tourism in Central and Eastern Europe. While the process of mass tourism-induced urbanization has declined significantly since the collapse of the socialist regime, the sprawl of urban (built up) areas into rural territories persist. Given the unregulated nature of urbanization at the forefront, we emphasize the importance for policy makers and local stakeholders to control further transformations of semi-natural and natural areas into built up areas along the shoreline. Achieving sustainable LULC management in lakes affected by mass tourism, such as Lake Balaton, necessitates robust legislative and administrative efforts in spatial planning and regulation. This endeavour should be pursued as a shared interest among residents and tourists alike. © 2024 The Authors
