The aim of the "Arctic as a food producing region" - project is to assess the potential for increased production and added value of food from the Arctic region, with the overarching aim of improving economic and social conditions of Arctic communities. This report is the output from the first phase of the project, providing a description of the main food production and examples of conditions for food production in the Arctic areas of the countries involved. This will form the basis for further analysis of opportunities, driving forces and barriers for further development of arctic food production, in the next phase of the project. The project has participation from Canada, Denmark, Greenland, Iceland, Norway and Russia, and is endorsed by the Arctic Council Sustainable Development Working Group (SDWG).

Multilocation testing remains the main tool for understanding varietal responses to the environment. Here, Latvian and Norwegian hull-less and hulled barley varieties were tested in field experiments in Latvia and Norway in order to assess the varieties adaptability across environments (sites). Two Latvian (cv Irbe and cv Kornelija) and one Norwegian hull-less barley variety (cv Pihl) were tested along with one Latvian (cv Rubiola) and one Norwegian hulled barley variety (cv Tyra) under conventional and organic management systems. The grain yield, together with physical and chemical grain parameters were compared, and variety yield and protein stability detemined. Overall, grain yield of hull-less barley varieties was significantly lower than for hulled barley varieties regardless of climatic conditions and management system. However, in the organic farming systems this difference between barley types was less pronounced. The hull-less barley varieties cv Pihl and cv Irbe, along with both hulled varieties, had good yield stability across environments and were well adapted to both cropping systems. Hull-less barley varieties tended to contain more protein and β -glucans than hulled barley varieties. Despite being bred for local conditions in Norway and Latvia, our study shows that all the varieties used may be successfully transferred across countries.
