Potato sector is one of the competitive areas of the European Union (EU) agriculture. Although Eurostat declared that in 2015 Lithuanian share in the EU-28 harvested production was modest and composed only 0.7%, according to Food and Agriculture Organization of the United Nations (FAOSTAT), this crop remained on the list of top 10 commodities by net production value in Lithuanian agriculture. However, over the past decades the Lithuanian potato sector survived undesired transformations. The aim of this paper is to analyse the changes of the main indicators, related to the potato sector, and vertical price transmission among the chain of potatoes in Lithuania. The conducted research indicates the most important development trends of the potato sector and applies econometric techniques to investigate if there is any long-run relationship between the farm and retail prices of potatoes for the period of 2010 to 2016. Although the statistics show the shrinking production and domestic consumption of potatoes in Lithuania, the analysis of the vertical price transmission does not provide evidence of market inefficiencies. The Johansen cointegration test confirms the existence of a long-run relationship between the farm and retail prices, while the Granger causality test shows that there is a bidirectional causality between the examined series. The M-TAR model does not provide evidence of the farm and retail price asymmetry in the long run.

Current paper contains the research concerning the role and concentration of IT specialists in contemporary Latvia. It is based on theoretical findings about the location of creative class in certain areas that meet the requirements of technology, tolerance and talent. At the same time, the advantages of creative people staying in the area are undoubted. Creative class and, first of all, super-creative core of creative class bring economic and technological development into the area it is located at. The goal of the article is to examine areas of creative IT specialist concentration within Latvia. The statistics and dynamics of IT position increase were examined and trends found. In order to define the role of IT specialists in Latvia, the allocations of IT specialists across the country were analysed. Herfindahl-Hirschman Index of Information and communication industry employee concentration was calculated. It was found that IT specialists in Latvia are extremely concentrated. Riga planning region accumulates 91.51% of all IT specialists in Latvia.

Dairy cow production is an important livestock activity in the highlands of Madagascar and specifically in the Vakinankaratra region. Despite the increase of global milk production over the last decades, cow productivity remains low due to both quantity and quality feed constraints. Elephant grass and Italian ryegrass are the most cultivated forage grass, during the wet and warm season and the dry and cool season, respectively. An experiment under field conditions was carried out to evaluate the ability of the satellite-derived normalized difference vegetation index (NDVI) to develop a tool for estimating biomass yields of Elephant grass and Italian ryegrass. Results showed moderate to strong but significant relationship between plant height and biomass yield (R² = 0.64 to 0.92), between NDVI and biomass yield (R² = 0.52 to 0.73) and between NDVI and plant height (R² = 0.61 to 0.74) of Elephant grass and Italian ryegrass, respectively. These results suggest that NDVI has potential to provide a tool for dynamic monitoring and management of pastureland forage production. (Résumé d'auteur)
