Posouzení trendů aktivních a efektivních teplot v období 1961-2010
Kourek, Zdeněk
The work analyzes the meteorological element air temperature at three climatological stations. The aim was to assess changes in the values of temperature sum, and the sum of active temperatures (sum of temperatures over specified threshold) and the sum of effective temperatures (sum of temperatures over specified threshold - defined threshold) for the period 1961 - 2010. At the same time large vegetation season (number of days when the average daily temperature is consistently above 5 ° C), the main (number of days when the average daily temperature is consistently above 10 ° C the growing season) and the growing years (number of days when the average daily temperature is consistently above 15 ° C) was analyzed. These results were then compared with the proxy data from the field of plant and animal phenology. Pedunculate oak or English oak (Quercus robur) was chosen as a representative for the higher plants and the Great tit (Parus major) was chosen for the represenatives of the bird species in the Lednice area. On the basis of calculating the sum of active and effective sum, we can say that their values increase with time, as far as the number of days in the growing seasons. The results are regionally different.

The aim was to assess changes in the values of temperature sum, and the sum of active temperatures (sum of temperatures over specified threshold) and the sum of effective temperatures (sum of temperatures over specified threshold - defined threshold) for the period 1961-2009. At the same time large vegetation season (number of days when the average daily temperature is consistently above 5 ° C), the main (number of days when the average daily temperature is consistently above 10 ° C the growing season) and the growing years (number of days when the average daily temperature is consistently above 15 ° C) was analyzed.

Barriers of Development in Ethiopia: Structural Conditions and Strategies for Adaptation
Kuzmič, Michal ; Pavlík, Petr (advisor) ; Jeníček, Vladimír (referee)
The diploma thesis titled Barriers of Development in Ethiopia: Structural Conditions and Strategies for Adaptation is focused on analysis of environmental risk factors and their impact on economic development of Ethiopia. It further evaluates the effectiveness of concrete adaptation measures on both official policy level and community level. The thesis departs from refined version of Jared Diamond's five point framework for analysis of collapse of complex societies. Contemporary scholarly discourse of rapid population growth, deforestation & land degradation and climate variability is formalized into causal schemes and supported by current statistical data. The thesis concludes that adopted measures have had only limited effect on elimination of the respective risk factors. Thus, Ethiopia remains a long-term recipient of foreign humanitarian assistance, without which it would fall into state of economic collapse. To overcome this situation Ethiopia needs to transform its subsistence agricultural production system.
