—New Fall Term Online Course for Dalhousie Students—
Dalhousie Students can register through Dal Online.
Non-Dalhousie students can contact firstname.lastname@example.org or phone 902-893-6666 to register.
[Dalhousie students whom have previously taken this course include those in Environmental Science, International Development Studies, Landscape Architecture, Earth Science, Biology, Integrated Environmental Management, Philosophy, Sustainability and Society, and Plant Science. The course has developed a reputation among students and distance learning professionals for being one of the best organized online courses currently taught at the university.]
Course Description: This course focuses on selected best management practices (BMPs), such as treatment wetlands, buffer strips, rain gardens, or green roofs to mitigate against, or repair the damage caused by, waterside and watershed development in urban, suburban, and rural environments. That is the end goal, but in order to get there, we need to back up. In other words, before one can attempt to fix an environmental problem, one must understand how that problem was created; and before one can understand what is wrong, one must appreciate how something operates properly. As a result, the course begins by examining the roles of lakes, rivers, and wetlands in a natural, healthy landscape context. Next, the course moves on to review how selected anthropogenic disturbances have deleteriously impacted aquatic resources. Finally, the course concludes with examining a toolbox of remedial ecohydrological techniques that can improve or remove the environmental degradation. See overview of course topics below.
Learning Outcomes: The objective of this course is to introduce students to the one of the most popular and important forms of contemporary environmental management: water sensitive design. The course approaches this goal through the fields of waterscape ecology and ecohydrology, which blend together science, landscape architecture, and eco-engineering. By the end of this course, students will be able to:
- Understand the important role of water in global history and the newly emerging paradigm of ecohydrology
- Understand how lakes, rivers, and wetlands operate in a landscape and ecosystem perspective
- Recognize the causes and severity of a suite of deleterious human influences on freshwater ecosystems in rural, suburban, and urban contexts
- Understand the diversity of options available to improve environmental conditions in terms of water quality and quantity
- Foster an appreciation for inter-disciplinarity, in particular the ability to study and analyze projects holistically in terms of deliverables through the co-dependent lenses of science, landscape architecture, and eco-engineering
- Develop and hone their critical skills in reviewing, synthesizing, and distilling information in the form of digital presentations and written assignments

Course Format and Marking: For each week, learning material is presented in several different formats. First, a set of power point presentations (PPTs) are provided that contain information distilled from many pertinent sources. These PPTs contain voice-over dialogue by the professor to guide the student through, while emphasizing the most important elements therein. Next, one or several video lectures are viewed. These are our virtual guest speakers -- representing some of the world’s leading practitioners and researchers – who were filmed previously at a series of conferences run at Harvard and Dalhousie Universities.
Each week students have to produce a list of short salient points that demonstrate they have viewed the online material. They will also read a chapter in the assigned book and engage in an online discussion.
There is no final exam. In addition to the weekly salient points, students will produce two short critiques of published papers from the literature, write a thematic essay about a topic of interest, and participate in a conceptual design project to improve conditions for a real-world location of their own choosing.
