Trends in Lakeshore Zone Development: A Comparison of Polish and Hungarian Lakes over 30-Year Period

(1) Background: This paper presents the land use and land cover change processes in the lakeshore zone in Poland and Hungary during 30 years. (2) Methods: Land use and land cover (LU/LC) maps were prepared using topographic maps and orthophotograph maps scaled 1:10,000. The study based on GIS data and field research. (3) Results: A significant increase in the area occupied by tourist and recreational infrastructure and forests in the lake shore zone was found in both countries. In Poland, this increase occurred mainly at the expense of arable land, which was a positive phenomenon. In Hungary, however, the main threat to the lakeshore zone was the increase of built-up area at the expense of semi-natural area. While the decrease in arable land was positive from an environmental point of view, the main threat to the Hungarian lake shore zone was the increase in built-up areas at the expense of semi-natural land. The results showed a positive correlation between the area of urbanized land and the area occupied by tourist and recreational buildings on the Polish lakes. There was no such correlation at the Hungarian lakes. (4) Conclusions: The most beneficial change in land cover for the lakes was the increase in forest area in the lake shore zone in both countries studied. Taking into account the results of previous studies, three main trends of changes in land cover and land use in the lakeshore zone were identified. These results shed new light on the problem of land use around lakeshores.

Automated summary

This paper presents the land use and land cover change processes in the lakeshore zone in Poland and Hungary during a 30-year period. Land use and land cover maps were prepared using topographic maps and orthophotograph maps scaled 1:10,000. The study utilized GIS data and field research. The results showed a significant increase in tourist and recreational infrastructure and forests in the lake shore zone in both countries. However, the increase occurred mainly at the expense of arable land in Poland and at the expense of semi-natural area in Hungary.
