The objective of the present thesis is to evaluate economic activities of a medium-sized agricultural farm in a real environment. The theoretical part of the thesis is engaged with the problems of the current scale of use of the landscape by farmers who continue to lay emphasis primarily on the economic function. Subsequently, in pursuance of our research, an alternative method of farming, i.e. organic farming, is described, along with the contemporary situation of this sphere in the Czech Republic. The last chapter of the theoretical part examines the Common Agricultural Policy of the EU and the tools thereof. In the framework of our research, the area of interest in which the farm observed works is described, and processes of the farm´s economic activities and economic evaluation are delineated. Next, environmentally-friendly landscape measures are proposed which take into consideration both the ecologic and social functions. This method of farming is evaluated in terms of economy and this evaluation includes an outline of the problems of the system of subsidies

This work was created as a response to the drought in the summer of 2015, which revealed the risks associated with a lack of moisture in the soil due to inadequate management landscape. The main objective is to select areas in the chosen territory where it would be desirable to implement measures that would lead to stabilization of drainage conditions, and support the landscape and territorial system of ecological stability (biodiversity).In addition to creating the appropriate landscape features and the introduction of environmentally friendly agricultural crops eligible planting fast-growing trees (FGT), which on agricultural land, for the interest of stabilizing of drainage conditions, in many ways irreplaceable alternate functions of the forest.This culture is therefore paid special attention; Work has focused on the estimation of the possible production of wood and possibility of its eventual use.The study is prepared as a possible basis for practical solutions to complex land arrangements in the cadastral areas. It was found that the FGT would be advisable to cultivate an area of up to 2461 ha.

A previously developed expert system for landscape visual quality assessment was evaluated for reliability and validity against four professional landscape architects, one of whom’s rules upon which the system was based, and two lay subjects. Results indicated that the system has good initial reliability and internal validity, but the external validity assessments appeared poor. It is believed that this was due to the subjects’ unfamiliarity with the system’s format and logical construction. For this reason, it is recommended that a training program be developed and the reliability and validity be reassessed, with and without training the subjects. / Master of Science

Grazing by domestic livestock is one of the primary ways by which humans have modified landscapes. At low stocking rates livestock grazing can modify vegetation community composition, but at high stocking rates grazing can also reduce vegetation productivity and initiate soil erosion, leading to land degradation. The country of Iceland has undergone severe land degradation over the past 1100 years, with over half of the former vegetation cover being lost, and the remainder having depleted productivity. This work focuses upon the role that grazing by domestic livestock played in this degradation, and how the interactions between farm management, vegetation cover and climate affected grazing patterns in space and time. The aims of the research were achieved by constructing an environmental simulation model, called Búmodel, which allowed a cross-disciplinary approach that integrated landscape ecology, environmental archaeology and historical analysis. Búmodel was loosely coupled with GIS so that spatially based model inputs and outputs could be displayed and analysed in map form. The purpose of Búmodel was to predict spatial and temporal patterns of vegetation biomass production and utilisation (through grazing and hay-making) with a view to commenting on vegetation degradation in the pre-modern period (pre-1900 AD). The model was parameterised using contemporary and historical Icelandic agricultural data. Model validation was undertaken using sensitivity tests and comparison with data from an independent grazing experiment in the north of Iceland. Búmodel was then applied to two contrasting study areas: Vestur- Eyjafjallahreppur, a farming community on the south coast of Iceland, and Hofstaðir, a farm estate in the north east of the country, situated inland by Lake Mývatn. These applications demonstrated the importance of farm management in avoiding land degradation and in ameliorating the impact of climate. They also established the usefulness of Búmodel as a tool for the investigation of human and environmental interactions in Iceland.

<p>The oak district of Östergötland is one of the largest oak forests left in Europe and it harbours many threatened species dependent on old hollow trees. In this study, the saproxylic beetle <em>Osmoderma eremita</em> living in hollow oaks was used as a model species and parameterised for a metapopulation model (the incidence function model) at the level of individual trees. The aim was to set up a number of conservation management scenarios, where new oaks were added to increase the quality of the matrix and then simulate the resulting metapopulation occupancy, using three levels of dispersal. A real data set of hollow oaks was used as the base for modeling. Oaks were added to cells in a lattice covering the study landscape, where cell size, cell position and numbers of oaks per hectare were varied. The results show that a larger area of added oaks and a greater number of oaks per hectare will give a higher increase in total occupancy, no matter the dispersal, but the second smallest cell size used (3.4 km2 ) will give the highest response per effort for medium and high dispersal abilities, and smaller cells with greater number of oaks per area can be more effective. The spatial position of the increase in occupancy differs depending on dispersal ability of the focal species and should be considered in conservation management work. For unoccupied cells, the effort required to get the cell occupied will be smaller for cells having a greater number of oaks.</p>

<p>Attention to participatory watershed management is increasing across the developing world<em> </em>as<em> </em>soil erosion continues to degrade agricultural land; reservoirs and irrigation infrastructure are clogged with sediment. The realization of the importance of watersheds is crucial for sustainable utilization especially in developing countries where rural livelihoods and economies are highly dependant on the exploitation of natural resources. The Lake Victoria basin is characterized by high population pressures, low productive subsistence agriculture, poor farming methods, loss of soil fertility and deforestation due to demand of fuel wood and charcoal, timber and building materials that are posing serious threat to watersheds. High population density in the basin also means new needs emerge too fast to which rural societies cannot respond in time leading to more area expansion for agricultural land. In spite of positive efforts under the Lake Victoria Basin Commission, there remains a huge gap between policy and institutional framework development at the top level and the actual implementation of actions on the ground to prevent land degradation, soil erosion and decrease sediment load. The study focused on Kagera and Nyando catchments of Lake Victoria Basin and aiming to establish if there exist and the extent to which participatory watershed management has been implemented on the ground to decrease land degradation and sediment load. It therefore provides an insight into watershed management in the Kagera and Nyando catchments by illustrating the link between policy formulation and actual implementation and enforcement.</p>
