Th e article analyses trends in the territorial and commodity structure of the Czech foreign agrarian trade and aims to identify changes which have occurred during the last decade. Th e main emphasis has been put on the period after the accession to the EU. Primarily such changes are identifi ed, that occurred in the relation to the EU-Member States and to third countries. Th e results show that the value of agricultural exports and imports was growing during the surveyed period while the growth rate of agricultural exports was above the growth rate of agricultural imports. Agricultural exports increased from CZK 78 billion in 2005 to more than CZK 160 billion in 2013 and the imports rose from CZK 103 billion to more than CZK 184 billion in the same period. Th e territorial structure of the foreign agrarian trace is continuously concentrating on the EU-Single Market, both in terms of exports and imports. Exports of milk, milk products, cereals, beverages, food preparations, tobacco and tobacco manufactures, cereal preparations, food residues and waste, oilseeds, vegetable fats and oils, sugar and confectionery belong to the most important commodity aggregations. Th e share of processed products in the total exports increased and reached currently about 7%. Th e export -import coverage ratio reached a satisfactory trend as well. Although the Czech Republic does not have ideal conditions for the export-oriented agriculture, the country is able to gain comparative advantages, at least at the level of following aggregations: HS10, HS01, HS12, HS24, HS04, HS17, HS15, HS11, HS16, HS22, HS03 a HS13.

Th e paper analyses the current position of the Russian Federation in the global market of agricultural products and foodstuff s with the accent on the comparative advantage of Russian agricultural exports in relation to specifi c regions and states. Th e key purpose of the research is to classify the most signifi cant changes in the structure of Russian agricultural exports. Th e results show that the structure of Russian trade is changing continuously and evolving along with the process of economic transformation and trade liberalization. Exports become less diversifi ed and are concentrated in a few segments. From the perspective of comparative advantage, cereals, fi sh and vegetable oils are the segments of Russian exports which become more signifi cant. Th e comparative advantages of Russian exports are strengthening mostly in the case of African, Asian and CIS countries.

Wild mushroom foraging has a long tradition in Central European countries. Protein from wild mushrooms is an important part of Central European diets and has served historically as a meat protein substitute. In view of climate change, this protein source may become scarce. This study investigated the effects of temperature and precipitation on wild mushrooms using the Dickey–Fuller test and ordinary least squares method. The results from the Czech Republic show that when the precipitation change was increased by one unit, the change in the amount of foraged mushrooms went up by twenty-seven tons, while the factor of temperature was found to be statistically insignificant. This indicates that with a decline in precipitation, possibly due to climate change, there will be a decline in the amount of wild mushrooms foraged.
