In recent decades structural changes in the forestry sector have changed forest owners' characteristics and thus the member base of forest owners' associations. More general social trends have also changed how individuals and organizations interact with each other. A major challenge for the forest owners' associations is thus to adapt their service offers and organizational structures to fit the needs of current and future members. The objective of the project this thesis is based upon was to examine processes that are shaping the future membership of forest owners' associations in Sweden and identify elements that are likely to affect their relationships with members and (hence) their cooperative nature. To meet this objective, the issue was addressed from different angles and organizational levels in studies reported in four appended papers. Paper I showed that renewal of district councils is a slow process in which election committees play a central role. However, they were found to act passively and select candidates from narrow pools, which restrict the councils' representativeness and raises risks of strategic misalignment with members' interests as it severely limits inputs from several user groups in decision-making processes. Paper II showed that in order to meet the changing member needs the organizations are currently focusing their strategic efforts on developing new services to support members' management activities and ownership issues, improve education offers, and become strong political actors. Paper III showed that members who had traded timber with the association displayed significantly higher affective commitment, but not calculative commitment, than both non-members and members who had traded with other organizations. Thus, the findings suggest that the associations should focus on communicating their core values and strengthening members' identification with the organization, as this will have stronger effects on their loyalty than fostering calculative relationships. Paper IV provides support for the findings in Paper II, showing that young adults generally have limited familiarity with forestry activities. Further they rarely discussed forest issues with their parents. Thus they did not feel comfortable in discussing their own future as potential forest owners since they lacked understanding of the personal implications for them in practice. A key highlighted finding is that the main challenges for the organizations are connected to their democratic governance processes.

Few studies have previously investigated how poor animal welfare might be associated with infection of zoonotic pathogens in humans. This paper assesses the predictive value of the presence of Campylobacter spp. in broiler chicken flocks when animal-based measures related to footpad dermatitis, hock burns, body lesions and arthritis are identified under commercial conditions (high density). The study population included 32 flocks analysed on farm and at slaughter, slaughtered between April and August 2008 in six different slaughter plants in Brittany, France. Welfare and health indicators are those indicated by the European legislation and sampling was carried out in the framework of the European baseline survey on the prevalence of Campylobacter in broiler chicken. Caecal contents, sampled both on farm and at slaughter, and carcass skin samples from the neck and breast at slaughter, were investigated for the presence of Campylobacter spp. Logistic models/classification trees were used to estimate the probability of the presence (or absence) of a specific foodbome pathogen in a flock based on specific animal-based measures (or combinations of measures) in order to study the potential relationship between welfare indicators and foodbome pathogen prevalence/incidence levels. On farm, flocks with more than 25% animals with severe lesions on between 25 and 50% of the footpad are predicted to be Campylobacter-positive whereas flocks where less than 13 individuals have arthritis are predicted to be Campylobacter-negative. The error rate on farm and at slaughter was 10 and 4% respectively indicating good predicting abilities. A poor welfare environment may result in stress, which reduces chicken immunocompetence making them more susceptible to Campylobacter spp. An infection with Campylobacter spp may lead to impaired defence and susceptibility to other pathogens which may result in greater intestinal excretion. Poor welfare and high growing rate lead to digestive troubles that lead to litter humidity. Litter humidity that, among other things, causes footpad dermatitis may also influence the horizontal transmission of the Campylobacter spp. infection due to the normal coprophagic behaviour of poultry. Reducing welfare problems by a better management of rearing conditions would not only improve broiler welfare, but it would also decrease the risks of Campylobacter contamination, of carcass condemnations and of economic loss for the poultry industry.
