Firms in the agri-food industry are embedded in a system of institutions, regulations and policies that shape their economic environment and affect their conduct and performance. Changes in this system can propose new challenges for the firms that need to adequately and efficiently change and adapt to the emerging environment. The following article examines how deep structural changes in the institutional and regulatory setting can be effectively addressed by organizational innovation and what can be the catalysts behind a successful innovation effort. In doing so the analysis examines the case of Valio, the largest Finnish dairy company and its reconstruction effort due to Finland’s EU accession in 1995. After years of restructuring and changing its business model the company remains a major player in Finland and one of the most well-known brands in the region.

Climate and weather variability affect agricultural crop production. The North Atlantic Oscillation (NAO) is the variation in air pressure difference in the northern Atlantic Ocean. A positive NAO index with higher than normal air pressure near the Azores and lower than normal near Iceland results in warm and wet winters in northwestern Europe. A negative NAO index gives opposite climatic effects in this region. We determined the effect of the NAO on the risk of frost injury in winter wheat for conditions that represent northwestern Europe by applying the FROSTOL model to dynamically simulate hardening, de-hardening and other physiological processes determining frost tolerance and frost injury in winter wheat. This model uses soil surface temperature and snow cover as driving variables. In total, 53 winter seasons from 1957-58 to 2009-10 were simulated to account for historical trends and variations in the NAO. Monthly and seasonal mean NAO indices for all years within this period were categorised into positive, neutral or negative phases. The winter wheat simulations included 3 locations in Norway (Apelsvoll, ås and Kvithamar), 2 wheat frost tolerance types and 3 planting dates. The results showed that negative NAO phases, especially in February and March, increased the risk of frost injury in winter wheat. The risk of frost injury was higher at Apelsvoll and ås than at Kvithamar, especially in negative NAO phases or after early planting. The results obtained can be used to design crop management practices and systems with higher production security.

There is increasing concern that the intensification of dairy production reduces the concentrations of nutritionally desirable compounds in milk. In this study we therefore compared important quality parameters (protein and fatty acid profiles, α-tocopherol and carotenoid concentrations) in milk from four dairy systems with contrasting production intensities (in terms of feeding regimes and milking systems). The concentrations of several nutritionally desirable compounds (β-lactoglobulin, omega-3 fatty acids, omega-3/omega-6 ratio, conjugated linoleic acid c9t11 and/or carotenoids) decreased with increasing feeding intensity (organic outdoor ≥ conventional outdoor ≥ conventional indoors). Milking system intensification (use of robotic milking parlours) had a more limited effect on milk composition, but increased mastitis incidence. Multivariate analyses indicated that differences in milk quality were mainly linked to contrasting feeding regimes, and that milking system and breed choice also contributed to differences in milk composition between production systems.
