Zoos as socially constructed institutions in changing social and territorial contexts
Nekolný, Lukáš ; Fialová, Dana (advisor) ; Šantrůčková, Markéta (referee) ; Boltižiar, Martin (referee)
This dissertation deals with research of the zoo as a social construct, which in its history and form represents the development of the relationship between society and nature, or man and animals. At the same time, it is a specific cultural landscape reflecting other changes in paradigms and needs in society. The current form of zoos has always reflected various economic, political, environmental and cultural aspects, or opinion and spatial changes of society. This work is a contribution to the discussion of the application of thematization typical of contemporary experience-oriented society. The aim of the thesis is to characterize the development of zoos and their current form in Europe, where this concept originated at the turn of the 18th and 19th centuries, and to discuss regional differences regarding the different geographical context of the post-socialist space. From the geographical point of view, this is a topic rarely addressed so far, both from a theoretical (the zoo as an example of the specific landscape) as well as a regional approach. The first part provides a theoretical framework by means of a discussion of scientific literature and formulating the starting points of the research based on selected concepts and paradigms (social constructivism, the relationship between man and...
Classification of global environmental systems according to the level of anthropogenic transformation
Hrdina, Aleš ; Romportl, Dušan (advisor) ; Boltižiar, Martin (referee) ; Václavík, Tomáš (referee)
The topic of the doctoral thesis is the development of a comprehensive classification of global environmental systems based on a geographical synthesis of abiotic, biotic and anthropogenic factors. The dramatic changes in the Earth's natural environment, the noticeable loss of biodiversity and the increasing impact of human activity in many different aspects raise the need for a comprehensive classification that provides an appropriate spatial framework for assessing the impacts of these changes. Several global classifications have been developed in the past, but most of them only work with various natural environmental gradients (especially climate or relief). However, most regions of the world have been so fundamentally affected or even completely transformed by human activity that the omission of anthropogenic factors in comprehensive environmental classifications may lead to erroneous conclusions. For this reason, new global environmental classifications have recently begun to emerge abroad that attempt to deal with anthropogenic changes to the natural environment and include them in a comprehensive assessment. The proposal of a methodology and the actual creation of the classification of global environmental systems based on abiotic gradients, biodiversity distribution and spatial...
Spotřeba palivového dřeva a dřevěného uhlí v domácnostech v okrese Kalomo, Zambijská republika
Boltižiar, Martin
The topic of the thesis was to establish the consumption of firewood and charcoal in the Southern Province of the Republic of Zambia. Data collection, field survey and questionnaire survey and collection of all background information was carried out in rural agricultural camps and in Kalomo town. Information on firewood and charcoal consumption in the area as well as socio-economic information on the inhabitants was obtained. It was found that an average rural household of 7 members consumes 62 kg of firewood per week, or approximately 19 kg of charcoal per household. The approximate annual household consumption is 3 217 kg of firewood or 997 kg of charcoal per household. Charcoal is produced in the countryside from local tree species and sold mainly in towns to residents who own a charcoal stove. All the data can be further used to establish fast-growing stands that would be used by local people in their area for regular logging or subsequent charcoal production and conservation of native tree stands.
Prioritization in nature conservation: Šumava National Park as a case study
Janík, Tomáš ; Romportl, Dušan (advisor) ; Václavík, Tomáš (referee) ; Boltižiar, Martin (referee)
In recent decades, we have been facing negative changes to the environment across the world. Landscape changes affected by anthropogenic activities and new forms of land use have led to the decline of suitable habitats, landscape fragmentation, and insufficient landscape management, all of which cause biodiversity loss. One of the basic instruments which should prevent these negative changes is spatial nature protection. Often, it is in opposition to other interests in the area. Due to these different interests, it is essential to know the area and set its values and priorities for nature protection. Šumava National Park was chosen for this study as a relatively large and compact area with a high degree of protection, which is differentiated based on zonation, and also with a good data basis as well as turbulent management development. Using landscape-ecological and geographical approaches, several outputs were subsequently created analysing values and priorities of the area. The aim was to contribute to the debate on the management and zonation of Šumava National Park and protected areas in general. The approach consists of a few steps; first the area was characterized from the physical- geographical, socioeconomic, and management point of view. Moreover, a comparison was made with Bavarian Forest...
Hodnocení zdravotního stavu týku (Tectona grandis) na plantáži v podmínkách suchých tropů v Nikaragui
Boltižiar, Martin
The goal of this project was to inventory control the health and the quality of Teak (Tectona grandis) stands on a tree farm in Nicaragua. There have been examined rows in lotes (stands) and measured following conditions: the health condition of a tree, microorganisms on the tree, cross-grain of wood, sapless tree, double stem and doddered top. The second part of the project has been done on experimental areas where all the trees were inventoried in every row. With collected data percentages were calculated for all observed attributes. From the results of the work we can tell the plantation still has a potential to grow stands of good quality.
