Course unit details:
Peatlands Under Pressure
|Unit level||Level 3|
|Teaching period(s)||Semester 1|
|Offered by||School of Environment, Education and Development|
|Available as a free choice unit?||Yes|
Peatlands are diverse environments. They span across all continents from the bogs, mires and permafrost in the Northern Hemisphere to tropical peat swamps in South East Asia and Africa. Peatlands are the world’s largest terrestrial carbon stock, containing more than twice the carbon found in all the world’s forests. However, our peatlands face an uncertain future - the IPCC identifies peatlands as particularly vulnerable to future land use and climate change. Understanding and preserving these valuable environments is therefore of vital importance, which is why peatland science is a major research focus of Geography at Manchester.
The course unit will introduce the fundamental concepts and key issues of peatland science. Through a combination of lectures, seminars, and fieldwork you will learn about the physical processes that shape peatlands, and the importance of solid scientific grounding for effective peatland management and policy development. In particular, the role of the peatlands in terrestrial carbon cycling and flood mitigation will be explored, along with the controversies surrounding the use of fire as a management tool. We will visit the department’s research catchment in the Peak District where you will carry out your own field projects, giving you hands on experience of research design and field and lab techniques. [See section on Learning and Teaching Processes for details on psooible COVID-19 accommodations]
- provide an understanding of how peatlands form and function
- explore the recent history of the UK peatlands to gain an appreciation of the impact of human activity and climate change on these fragile environments
- design and execute a field project which will strengthen research design and analytical skills to aid dissertation research
- provide a scientifically grounded understanding of peatland environmental management, focussing on the three key issues of carbon, fire, and restoration
Teaching and learning methods
The course unit will be delivered through a combination of lectures, fieldwork, lab classes and seminars. The unit is divided into three blocks. Over the first three weeks the fundamental processes and issues will be introduced during lectures. This is followed by a series of workshops, fieldwork and lab classes, which will allow you to build on the introductory material to design and execute your own problem-based projects. Finally, during the last three weeks of term we revisit some key issues in more detail in lectures and seminars, including discussion sessions and talks from guest speakers.
Although this module has a substantial field and lab component, the Intended Learning Outcomes can still be met if part/all of the module has to move online:
- A virtual field trip can replace the physical trip, which will ‘stop off’ at key points in the catchment using a mix of media, key readings, and structured questions to get you to engage with the processes at work (much like the physical trip but without the rain!)
- In place of sample collection and labwork, we can draw on a wealth of existing data from the field site that you can work on for your projects. We will make use of a series of online practicals provided by the labs team to teach you about the field and lab techniques that were used to derive the data.
- We can supplement lab time with online data analysis and presentation workshops, so you will still gain hands-on on experience of valuable practical skills.
Knowledge and understanding
- Understand the processes underpinning hydrological, geomorphological and ecological functioning of peatland systems.
- Understand the processes controlling uptake and re-distribution of nutrients and pollutants in peatlands.
- Appreciate the importance of the environmental history of peatland systems to their present-day functioning.
- Be aware of the key issues surrounding ongoing research and management of peatlands today.
- Contribute in an informed manner to debates about the use and management of peatland environments.
- Review and summarise relevant material to provide rationale for a research project and construct a focussed literature review.
- Be aware of the main techniques used to study peatland environments from both a contemporary and historical perspective.
- Have a working knowledge of a range of analysis methods.
- Analyse and present environmental data to a high standard
Transferable skills and personal qualities
- Data analysis and presentation, critical thinking, writing, communicating complex ideas, and self-directed learning
- Confidence to critically engage with and contribute to key debates and controversies surrounding peatland management
The course is assessed by:
• Literature review submitted mid semester (25%)
• Project report submitted near the end of the semester (50%)
• Written examination at the end of the semester (25%)
Feedback will be provided in the following ways during this course unit:
- Continuous verbal feedback through discussion in lectures and seminars;
- Ongoing verbal feedback on project work during workshops and lab classes
- Verbal and written formative feedback on project data during drop in sessions;
- Written feedback on the literature review, project report and exam.
- Verbal feedback on any course unit issue by appointment or during consultation hours.
We will provide specific reading lists for each lecture, but broad course texts include:
