Integrated national-scale assessment of climate change impacts on agriculture: the case of the Czech Republic
Arbelaez Gaviria, Juliana ; Boere, E. ; Havlík, P. ; Trnka, Miroslav
In recent years, investigating climate change impacts in the agricultural sector at the national level has become a priority for adaptation decision-making. Most of these studies quantify the impacts\nof biophysical effects and often ignore the cross-sectoral interactions and economic effects on relative competitiveness, international trade, global food supply, and food prices for the Czech Republic. Ignoring future productivity changes globally under climate change scenarios can underestimate or overestimate climate change impacts at the national level. Here, we use GLOBIOM-CZE, a global economic model, as part of a climate change impact assessment framework to evaluate the impacts on the Czech agricultural sector in terms of environmental and economic indicators. By comparing with the baseline, the ensemble of scenarios suggests a decrease in crop area and production while increasing grassland, positively affecting livestock production by mid-century. Corn and barley show the most adverse response in production and area, while rapeseed increases under scenario RCP 8.5 with CO2 fertilization effect. Livestock products production is projected to increase, especially bovine meat and milk, as within RCP 8.5, no constraints are placed on growing greenhouse gas emissions.

Perception of climate change impacts and adaptive capacity in organic agriculture
Říhová, Jana ; Vačkářová, Davina Elena (advisor) ; Pražan, Jaroslav (referee)
This thesis deals with the perception of climate change issue and adaptive capacity of organic farming systems in the Czech Republic. The aim of this thesis it to investigate organic farmers' attitudes toward climate change and their willingness to adopt adaptation practices. The method used in this thesis is based on questionnaires that were distributed among organic farmers in the period of January-March 2015; 52 questionnaires were subsequently analysed. The results indicate that the majority of organic farmers surveyed believed that the global climate change is occurring, expected negative climate change effects and observed higher frequency of extreme weather events. Most of the respondents also acknowledge the importance of adaptation practices and their own responsibility in adaptation. The statistical analysis revealed that both the belief about climate change and perception of associated threats may serve as predictors of the willingness to implement adaptation measures.
