Water Problems

In this paper, we discuss the multiple dimensions of water security and define a set of thematic challenges for science, policy and governance, based around cross-scale dynamics, complexity and uncertainty. A case study of the Saskatchewan River basin (SRB) in western Canada is presented, which encompasses many of the water-security challenges faced worldwide. A science agenda is defined based on the development of the SRB as a large-scale observatory to develop the underpinning science and social science needed to improve our understanding of water futures under societal and environmental change. We argue that non-stationarity poses profound challenges for existing science and that new integration of the natural sciences, engineering and social sciences is needed to address decision making under deep uncertainty. We suggest that vulnerability analysis can be combined with scenario-based modelling to address issues of water security and that knowledge translation should be coupled with place-based modelling, adaptive governance and social learning to address the complexity uncertainty and scale dynamics of contemporary water problems.

Bilingual School

Abstract Immersion-style bilingual school programs have proven to be effective ways for children’s acquisition of additional languages. However, such programs seem to be scarce across the world in comparison to the value people attach to bilingual skills and bilingual education. Through a case study of a successful Mandarin bilingual program in western Canada, the study hopes to explore the factors that contribute to the success of such programs in North America. The study points to the importance of government language policy environments, the attitude of local school boards, the commitment and active involvement of parents, and the availability and recruitment of quality teachers as key factors for the success of a bilingual school program.
