Man-related phenomena occur not only in areas used by the industry. They can be also found in arable land, including river valley bottoms where natural aggregate is mined: sand, gravel, bolder. The extent of transformation of a valley depends on the size of the output. Changes are the most intensive in river bottoms or terraces where the aggregate is easily available and it can be used as quality construction material. The author deals with the problem using the valley of the Wisłoka River, the largest natural aggregate mine in the Carpathians, as an example.
In the late 90-s of the 20th century there was a dramatic increase in the number of internet connections, by ca 35%. The rise was even higher for cellular telephony - more than 45% per year (only 6% annually in the case of stationary telephony). There are few studies on the geographical distribution of cellular telephony in Poland, and they deal mainly with technical aspects. The article is an attempt to define factors determining the siting of base stations (BTS) - the most visible part of technical infrastructure of the cellular telephony networks, as well as their impacts on Poland’s landscape.
