Cultural landscape potential and local strategies of rural area development

The article presents results of research and implementation studies conducted at the University of Agriculture in Krakow within the project VITAL LANDSCAPES realized with the support of the CENTRAL EUROPE Programme funded by the EU. The research covered the area of the manor and park complex funded by the family of von Nostitz in Mściwojów. Project activities involved innovative combination of advanced 3D visualizations with the participation of local communities and decision-makers for the valorisation of local cultural landscape assets, which were regarded as important elements of local rural development strategies. Activities towards developing local strategies are now an important trend in Europe. They usually engage local and subregional stakeholders in the development processes in rural areas with special emphasis on the development of strategy concepts, in accordance with the principles of Agenda 21.

Runoff formation in terms of changes in land use - Mściwojów water reservoir area

Abstract Along the paper the size of peak runoff was assessed affected by the influence of changes in water catchment area by land use due to future planned agricultural changes. The investigations were conducted in the Winna Góra catchment area located in Mściwojów, Lower Silesian voivodship at the Mściwojów water reservoir. At present, the catchment is used as arable land, forest and meadows. In the future the area of sealed surfaces such as: roofs, roads and car parks will increase. This can contribute in the change of water balance components. Analyses has shown, that changes in the use of a catchment area lead to reduction of surface flow time from the catchment (less resistance to motion) - in effect it causes increase of the runoff volume at about 28%. The increase of the water runoff volume may have significant influence on the Winna Góra development and functions as well as volume of water run into the Mściwojów water reservoir. To counteract the results of adverse changes caused by the catchment sealing - it is recommended for the investigated area to apply a balanced approach. This would consist of retaining precipitation water in its place of origin. W artykule przedstawiono wielkość zmian odpływu powierzchniowego w wyniku przyszłych planowanych zmian użytkowania rolniczego zlewni. Badania prowadzono w obszarze Winnej Góry znajdującej się w miejscowości Mściwojów (województwo dolnośląskie) w zlewni zbiornika wodnego Mściwojów. Obecnie zlewnia to głównie przestrzeń rolnicza i lasy. W przyszłości obszar powierzchni zlewni dopełnią powierzchnie takie, jak: budynki, drogi i parkingi. Może to przyczynić się do zmiany elementów bilansu wodnego zlewni. Analizy wykazały, że zmiany w użytkowaniu zlewni prowadzą do skrócenia czasu spływów powierzchniowych ze zlewni (mniejsze opory ruchu), co powoduje zwiększenie objętości odpływu o około 28%. Zwiększenie ilości odpływającej wody może mieć znaczący wpływ na rozwój i funkcje Winnej Góry, a także dopływ wody i pojemność zbiornika wodnego Mściwojów.

Evaluation of soil water erosion risk in the Mściwojów water reservoir drainage basin on the basis of numeric modelling

Summary The paper presents the evaluation of soil water erosion risk of the Mściwojow water reservoir drainage basin. In the present study, modelling with the use of GIS (Geographical Information Systems) and RUSLE (Revised Universal Soil Loss Equation) erosion models were exploited. Values of topographic factor (LS) were calculated after formulas proposed by Moore et al. [1991] as well as Desmet and Govers [1996]. The results of erosion prognosis by means of RUSLE method after Moore’s formula are by 40% higher than values evaluated after Desmet and Gover’s formula. Eroded soil mean mass from area unit during the year is estimated at the level of 10.35–14.53 Mg ∙ ha –1 ∙ year –1 , depending on computable formula used. Results of this research enabled to divide the drainage basin area into soil water erosion intensity zones based on predicted soil loss values according to Marks et al. [1989]. The study shows that water erosion risk of soil in the Mściwojow water reservoir drainage basin is very high. Almost one third of its area is located in the high and very high class of erosion risk.

Impact of the forest succession on efficiency of the arable land production

Abstract The paper presents the studies involving analysis of changes in shape of parcels of arable land under the influence of forest succession. The object of the research is the village Grębosze located in Świętokrzyskie voivodeship. The study material will cover all arable land existing in the studied village. The source of data were numerical registry maps from 1998 and 2013. The basic element of research, enabling comparison of changes in the efficiency of the production process are continuous parts of the parcels covered by one form of use. In the course of the output data processing and determination of the necessary technical parameters for the tested surface elements, the specialized tools and statistics were used. The studies were related to the evaluation of formation of these surface structures on the basis of their shape meter in the form of the so-called costs of cultivation. The obtained results make it possible to tell, to what extent the changes resulting from the consequences of the secondary forest succession influence the process of cultivation of neighbouring arable land.
