THE CANADIAN ATLAS ONLINE www.canadiangeographic.ca/atlas PRINCE EDWARD ISLAND – GRADES 9-12 Tourism, Climate Change and Sand Dune Coasts: Stresses, Adaptations, Opportunities? Lesson Overview This lesson is based on current scientific research. Changes in climate can result in changes to sand dune coasts – both to the shoreline and the dunes. They can also cause changes that impact tourist use of the coast. Changes in tourism, such as the number of tourists and the season of their visits, can also impact the coastline. In this lesson, students will conduct a field study to help them answer the following questions: How can the impacts on tourism interact with the impacts of tourism on a sand dune coast? Will tourism be helped or hampered by the anticipated warmer, drier summer climate of the future in Prince Edward Island; or are there positive adaptations? Grade Level Grades 9-12 (secondary school) Time Required Teachers should be able to conduct the lesson in one or two classes. Curriculum Connection (Province/Territory and course) Atlantic Provinces Curriculum for Social Studies: Council of Atlantic Ministers of Education and Training (CAMET): Prince Edward Island, other Atlantic Provinces May be adapted to any other jurisdiction affected by coastal tourism. Additional Resources, Materials and Equipment Required Teacher Background Information (attached) Canadian Geographic/NRTEE A Changing Climate poster-map Student access to computers and the internet Website: Climate Prosperity thematic module in the Canadian Atlas Online: http://www.canadiangeographic.ca/atlas/themes.aspx?id=climateprosperity&lang=En Copies of: “Student Questions for Consideration” (attached) Main Objective Students will consider the interaction of various factors that influence and impact the sand dune coasts of Prince Edward Island. They will discuss and understand the relationships between climate change, rising sea levels and coastal erosion. THE CANADIAN ATLAS ONLINE www.canadiangeographic.ca/atlas PRINCE EDWARD ISLAND – GRADES 9-12 Learning Outcomes By the end of the lesson, students will be able to: Recognize that environmental issues (the erosion of sand dune coasts in particular) involve multiple factors, both physical and human; Appreciate the necessity for careful analysis, data collection, and consideration of multiple parameters; Gain an appreciation for the sand dune coasts of PEI; Hypothesize possible scenarios dependent on variable factors. The Lesson The Lesson Teacher Activity Introduction Note to teacher: This lesson works best as a field trip or project. Become familiar with the “Teacher Background Information.” (attached) Have students examine the Climate Prosperity thematic module in the Canadian Atlas Online: http://www.canadiangeographic.ca/atlas /themes.aspx?id=climateprosperity&lang =En Use the Canadian Geographic/NRTEE A Changing Climate poster-map to identify threats to coastlines in Prince Edward Island due to warming temperatures and rising sea levels. Inform students that they will conduct research and complete a field study to find the answers to the questions on the “Student Questions for Consideration” sheet (attached). Discuss the idea that changes in climate can result in changes to sand dune coasts – both to the shoreline and the dunes. Ask the questions: How does storm activity influence sand beaches? How does storm activity influence dunes, both in the summer and the winter? Student Activity Through discussion and questioning, deduce that: Changes in climate and subsequent changes in sand dune coasts can also cause changes that impact tourist use of the coast. Changes in tourism, such as the number of tourists and the season of their visits, can also impact the coastline. THE CANADIAN ATLAS ONLINE www.canadiangeographic.ca/atlas Lesson Development How could the number of tourists affect the beaches and the dunes? Could changes in climate result in changes in tourist numbers, or in the length of the tourist season? How could the impacts on tourism interact with the impacts of tourism on a sand dune coast? Inform students that through field study these effects can be analyzed and documented. Lead a field study to photograph sand dunes and collect sand samples from a variety of beaches. Ask the following questions after labelling and sorting: Which is finer? Which would be easier to erode? How can you determine the direction of sand movement along a beach? Why does an increase in sea ice cover result in reduced beach erosion? How can you recognize ongoing erosion on a beach system over a period of years? Does most erosion occur during individual storms, or is it a slow, gradual process? What data or observations would help to answer these questions? Conclusion Ask students to compile a list of related environmental issues that influence sand dune coasts. Discuss the following questions: How could the tourism industry adjust to these issues? Will tourism be helped or hampered by the anticipated warmer, drier summer climate of Prince Edward Island? What steps could be considered to reduce the stresses on the dunes and coasts that would also enhance the PRINCE EDWARD ISLAND – GRADES 9-12 Prepare for the field study. Collect samples of beach and dune sand from variety of locations. Label compare, and categorize the grain sizes. Complete observations and respond to questions. Brainstorm where additional information and data might be gathered. Conclude: One of Prince Edward Island’s economic activities is tourism. Climate change and its effects on one of the main attractions, sand dunes, will affect the province. In order to understand the full effects of climate change, the province must carefully monitor the sand dune coastlines and plan for the future. The complexity of this issue means that careful analysis, detailed data collection and consideration of multiple stakeholders is necessary.

THE CANADIAN ATLAS ONLINE www.canadiangeographic.ca/atlas PRINCE EDWARD ISLAND – GRADES 9-12 Teacher Background Information • • • • • • • • • • • • • The impact of ongoing environmental change is evident in the landscape of Prince Edward Island. The coastline represents a critical area for the assessment of the impact of change. Storm activity generally results in erosion and narrowing of the beach; and coarsening of sediment (e.g. from fine sand to coarse sand or gravel). Winters with relatively limited sea ice and scarce snow cover along the beach permit increased erosion by storms. Coastal barrier beaches depend upon having an ample supply of sand to replace that transported laterally by currents along the shore. Sand supply has been curtailed in some areas by the erection of docks and breakwaters, interrupting the course of longshore drift. Rising sea levels are also resulting in coastal erosion. Some of the sand necessary to maintain the beaches is stored temporarily in the dune systems. Any loss of sand from the dunes, or transport of sand inland, has a negative impact on the amount of sand on the beaches. Windy conditions on loose sand with no vegetation cover causes dune erosion. Dunes become lower and migrate inland. Winters with relatively little snow cover on the dunes permit increased erosion. The rate of erosion is influenced by climate parameters (wind velocity and persistence; precipitation amount, types, and seasonality), proximity to the ocean, grain size, vegetation cover (type and extent), animal activity (both natural and domestic), and the extent, style, and duration of human activity. Other human activities, including ATV use and recreational fires, also result in degradation. Assessment of the relative impacts of tourists and local users must consider the relative numbers of people involved (allowing for multiple visits by local residents), as well as the differences in the type and location of their activities. The requirements of increased numbers of tourists, drawn by warmer, drier summers, could result in water shortages. An increase in the number of tourists increases the pressure on dunes, resulting in increased erosion and damage to dunes and vegetation. Wind is funnelled along trails, causing increased erosion and forming trough blowouts and deflation basins. The human-created features are not aligned parallel to the prevailing winds or dune orientations. The alignment of the troughs reflects routes of human traffic. Restriction of tourist traffic has resulted in decreased rates or almost complete cessation of erosion. An effective way to do this is to construct boardwalks across the dunes to the beaches. Warmer, longer summers could increase the number of tourists and lengthen the tourist season. An initial increase in tourism could lead to increased pressure on the dune coast, causing degradation and eventually making a less attractive environment for tourists. Tourists could be concerned about increases in storm (hurricane) activity and stay away. Sources: Catto, N.R., 2002. Anthropogenic Pressures on Coastal Dunes, southwest Newfoundland.

Why does snow cover reduce dune erosion in the winter? 2. Why does a snowy winter result in decreased dune erosion in the following spring? (Hint: where does the water produced by melting snow go?) 3. Would you expect dune erosion to be greater during a hurricane with strong winds and abundant rain; or during a dry period with lesser winds? 4. One person walking across a lawn causes no damage; 1000 people will wear a path through the grass. How many people are too many on a dune? 5. How could you limit the number of people on sand dunes without causing damage to tourism? 6. Do most tourists care about the dunes, or are they largely interested in the beaches? 7. Aside from foot traffic, what other human activities are most likely to cause the erosion of sand dunes? 8. Which animals could potentially cause problems if they were present in large numbers? 9. Is animal erosion of the sand dunes a potential problem in Prince Edward Island? 10. Is the pressure generated by tourists more or less than that generated by local residents? 11. What data or observations would help to answer these questions? 12. Have water shortages been a problem in parts of Prince Edward Island during some summers?
