Opis:
Beskid Niski należy do regionów karpackich o największych zmianach ludnościowych, które wraz z przemianami polityczno-gospodarczymi wpłynęły na przebieg granicy rolno-leśnej. W pracy pokazano zmiany powierzchni lasu, oraz przebiegu i kształtu jego granic od lat 1978–1980 do lat 2003–2004. Stwierdzono, że granica rolno-leśna w tym okresie uległa obniżeniu o około 18 m, a powierzchnia leśna wzrosła o około 5,5%. Wzrosły też wartości wskaźników świadczących o fragmentacji płatów leśnych. Wszystko to wskazuje na trwający tu nadal proces reforestacji, dla którego fragmentacja krajobrazu jest prawidłowym stadium przejściowym.
Beskid Niski is the region of Polish Carpathians, where the most significant changes in population took place. The depopulation started during the Second World War and continued until 1947, when the Lemkos were displaced from the region, which caused the abandonment of their farms and began the renaturalization process. Those changes as well as political and economic changes in Poland since 1990 are the factors which influenced pattern of the forest-field boundary in the discussed area. The author’s research was carried out in the Pasma Magurskie region, which is in the central part of Beskid Niski Mts. in Outer Western Carpathians (Fig. 1). The study area included also the Magura National Park. The main tectonic unit here is the Magura Nappe. The relief of Pasma Magurskie was formed by fluvial and denudation processes. As for altitudinal zonation, two vertical zones are distinguished here – the foothill vertical zone where original Tilio-Carpinetum betuli was transformed into agricultural fields, and lower forest vertical zone covered with Dentario glandulosae-Fagetum. As a consequence of depopulation settlement density is low here in comparison with other parts of Polish Carpathians. The author’s aim was to investigate changes in the geometry of forest-field boundary and its altitude between 1978 and 2004 in the Pasma Magurskie. Additionally, changes in the forest area were examined. The research was based on the map overlapping technique. Data derived from digitized topographic maps made in the 1978–1980 period and orthophotos of 2003–2004 years were compared and changes were analyzed. The total forest area in the region increased from 69,4% in 1980 to 73,2% in 2004 (tab. 1). At the same time the altitude of forest-field boundary lowered by c. 18 m. Also the values of metrics concerning fragmentation of forest patches increased considerably (tab. 4). It means that the process of reforestation, which through temporal fragmentation leads to the merger of landscape, is continued.

Opis:
The aim of the work described here has been to point to the relationships between the field-forest boundary and crop productivity as regards the present agrarian land-use structure in Poland, and to provide new opportunities for arranging the agrarian process and the spatial planning of the rural landscape in the context of the sustainable shaping of the field-forest boundary. Impacts of forests and woodlands on crop productivity have been assessed using available data from relevant Polish literature. An assessment of the plot-distribution pattern characterising farms in Poland was made on the basis of reference data from the Agency for the Restructuring and Modernisation of Agriculture. Finally, the possibility of afforestation of agricultural land has been evaluated within the existing legal framework, and on the basis of available data, with attention paid to the need to include organization of the field-forest boundary within the comprehensive management and planning of rural areas, and to preserve woody elements in patchy landscapes. This all creates an opportunity to test innovative approaches to integrated land use which combines the creation of public goods and local products based on participatory learning processes that bring in local stakeholders and decision-makers.
