Zatravňování, zalesňování a opouštění zemědělské půdy Česka po roce 1990 / Grassing, reforestation and abandonment of agricultural land of Czechia after 1990

Kříž, Jaroslav January 2015 (has links)
Jaroslav KŘÍŽ: Grassing, reforestation and abandonment of agriculture land of Czechia after 1990 The thesis deals with land use changes on the Czech territory, which run from 1990 to the present, focusing on extensification processes, primarily for grassing, reforestation and abandonment of agricultural land. Research will focus on revealing the factors that these processes at the level of individual agricultural parcels influence. Examined are both natural factors (slope, productive capacity of the soil) and socioeconomic factors (distance from settlements and roads, the number of owners of the area, the distance from the area of residence of the owner). Research is carried out in two model areas, which also correspond to the cadastral area. Current data are collected by field survey and then compared to the situation before 1990, which is shown in map sheets of the State Map derived 1: 5000. The natural factors have extensification processes influence both slope and the productive capacity of the soil. For socio- economic factors, especially the number of owners of the area, and the distance between their place of residence. The grassing, reforestation and abandonment of agricultural land also occurs on average smaller areas than those on which there are, for example, arable land, and also in...

Procesy extenzifikace využití ploch ve vnitřní periferii Česka po roce 1990 / Processes of land use extensification in the inner periphery of Czechia after 1990

Kříž, Jaroslav January 2016 (has links)
Jaroslav KŘÍŽ: Processes of land use extensification in the inner periphery of Czechia after 1990 The thesis deals with land use changes in the territory of the Czechia inner periphery, which run from 1990 to the present, focusing on extensification processes, primarily for grass planting, afforestation and abandonment of agricultural land. Research will focus on revealing the factors that these processes at the level of individual agricultural parcels influence. Examined are both natural factors (slope, productive capacity of the soil) and socioeconomic factors (distance from settlements and roads, the number of owners of the area, the distance from the area of residence of the owner).

Přírodní a společenské hybné síly extenzifikace krajiny Evropy a Česka po roce 1990 / Natural and societal driving forces of extensification of European and Czech landscape after 1990

Vojáček, Přemysl January 2012 (has links)
This master thesis focuses on extensification of agricultural production and land use, and on driving forces and factors that influence this process. The research concentrates on land-use changes resulting from the extensification of agriculture (especially grassing-over and abandonment of agricultural land) in last twenty years. Emphasis is put on an analysis of driving forces of extensification processes that have an influence on land-use change. Factors with an impact on extensification are divided into natural and socio-economic ones. Natural factors are represented for example by air temperature, precipitation, altitude, slope, or soil productivity. As socio-economic ones we consider for instance the Common Agricultural Policy of the European Union, Gross Domestic Product, population density, spatial exposedness, or patterns of use and ownership of agricultural land. These factors are studied on European, Czech and local scales. Data for this research were collected from international and Czech databases; on the local level there was performed the author's own field research. Results of this thesis are obtained by quantitative research that demonstrate the main influence of natural driving forces on the process of extensification in Europe. Land-use changes related with extensification of agriculture...

Hospodaření na trvalých travních porostech a struktura živočišné výroby v podnicích s jejich převahou / Farming on permanent grassland and structure of animal husbandry in enterprises with their superiority

SEDLECKÝ, Pavel January 2010 (has links)
The Thesis was elaborated on the theme: Farming on permanent grassland (PG) and structure of animal husbandry in enterprises with their superiority. The aim was to analyze number of cattle, milk and meat production, the proportion of PG in Czech Republic and detail in the South Bohemia. A working hypothesis was set as follows, that with increasing altitude, increasing the proportion of grassland. From 1989 till 2009 in the Czech Republic the acreage of grassland increased about 100 thousand he, but in the same period decreased by 2 100 000 pieces in cattle. This has resulted in insufficient load {--} 0.7 LU/he. For comparison I show the average load in the EU {--} 1.1 LU/he. The results show that the proportion of PG in the Czech Republic had increased, but grassing should be more focused. It should also improve the structure of livestock farming on PG and thereby achieve an increase in load and LU/he.
