Participation in organized activities is associated with many markers of positive youth development (PYD) such as improved self-esteem, social competence, and academic achievement (Mahoney et al., 2009). Sport is an extra-curricular activity that is particularly popular among youth, as nearly three quarters of Canadian children and adolescents are engaged in organized sport or physical activity (CFLRI, 2012). Much of the research in this area has examined sport programs which are explicitly structured to promote life skills or PYD outcomes; however, the sustainability of such programs has recently been called into question (Turnnidge, Hancock, & Côté, 2014). The purpose of this program of research was to conduct an in-depth case study of a successful, sustainable community youth basketball league. Study 1 was a qualitative descriptive exploration of coaches’ perceptions of the basketball league. This study provided a general overview of the structure and perceived benefits of the league, from the perspective of current coaches. Coaches highlighted the unique emphasis that the league places on fun and positive immediate sport experiences. Study 2 expanded on selected themes from Study 1, namely, the salience of the league’s culture and tendency for former players to return to the league as volunteers. This study used an ethnographic approach wherein the first author volunteered as an assistant coach on a basketball team over the course of a six-month season. This approach enabled him to gain considerable first hand insight into the organizational culture of the basketball league. The third and final study adopted a quantitative approach using both systematic observation and questionnaires to investigate the relationship between PYD outcomes and observed athlete behaviour during basketball games. A cluster analysis revealed the presence of two distinct groups of athletes characterized by relatively high and low perceptions of PYD outcomes, which were also associated with varying behavioural characteristics during competition. The results of these three studies provide a detailed blueprint of a successful youth sport program that has been sustained over 60 years. While not without limitations, many characteristics of the league should prove useful in structuring youth sport programs in other contexts.

Climate change is expected to have marked impacts on forest ecosystems. In Ontario forests, this includes changes in tree growth, stand composition and disturbance regimes, with expected impacts on many forest-dependent communities, the bioeconomy, and other environmental considerations. In response to climate change, renewable energy systems, such as forest bioenergy, are emerging as critical tools for carbon emissions reductions and climate change mitigation. However, these systems may also need to adapt to changing forest conditions. Therefore, the aim of this research was to estimate changes in forest growth and forest cover in response to anticipated climatic changes in the year 2100 in Ontario forests, to ultimately explore the sustainability of bioenergy in the future. Using the Haliburton Forest and Wildlife Reserve in Ontario as a case study, this research used a spatial climate analog approach to match modeled Haliburton temperature and precipitation (via Fourth Canadian Regional Climate Model) to regions currently exhibiting similar climate (climate analogs). From there, current forest cover and growth rates of core species in Haliburton were compared to forests plots in analog regions from the US Forest Service Forest Inventory and Analysis (FIA). This comparison used two different emission scenarios, corresponding to a high and a mid-range emission future. This research then explored how these changes in forests may influence bioenergy feasibility in the future. It examined possible volume availability and composition of bioenergy feedstock under future conditions. This research points to a potential decline of softwoods in the Haliburton region with a simultaneous expansion of pre-established hardwoods such as northern red oak and red maple, as well as a potential loss in sugar maple cover. From a bioenergy perspective, hardwood residues may be the most feasible feedstock in the future with minimal change in biomass availability for energy production; under these possible conditions, small scale combined heat and power (CHP) and residential pellet use may be the most viable and ecologically sustainable options. Ultimately, understanding the way in which forests may change is important in informing meaningful policy and management, allowing for improved forest bioenergy systems, now and in the future.
