Abstract
This study analyzed the temporal and spatial changes in land use taking place in two adjacent river valleys, located
within the Polish Carpathians. The land use in 1977 and 2009 was presented for selected areas. In one of the valleys,
a dam has been operating since 1994 along with a retention reservoir, which is an additional factor influencing the direction
and scale of the land use changes. An analysis using GIS techniques showed that the general directions of transformation
in both valleys in the land use structure are similar but with different intensity. In studied valleys a decrease of area
with agricultural land and gradual increase in the forested area have been observed. In the valley with the reservoir few
more changes were noticed. The decrease of the forested area by 5.5% and farmland by 8.2% on the areas submerged by
reservoir was observed. The strip fields pattern has been changed into more dispersed. The road network development
was also observed, as well as the change of nature of residential/agricultural buildings into residential/recreational.
