Natural hazards and their impacts: geo-hazards and atmospheric hazards

1. Natural hazards and their impacts: geo-hazards and atmospheric hazards KGA171 The Global Geography of Change Presented by Associate Professor Elaine Stratford Semester 1

2. Vulnerability L vulnerare – to wound; capable of being wounded; open to attack or damage; assailable Geographical imagination Emotional geographies Peter Monamy, Loss of HMS 'Victory', 4 October 1744

3. Part 1 Looking back, looking forward

4. Revising Lecture 5.3 Name and explain Wirth’s categories of the urban. Describe Mumford’s understanding of the relationship between spaces and people. What are six elements of city life that are seen as positive? Are these exclusive to the urban? Describe and exemplify the dynamic relationship between urbanization and industrialization. What did Ebenezer Howard mean by the town and country magnet? What is a slum? How is the existence of slums a geographical problem? Describe and explain the spatial patterns for (a) urban population as a percentage of total population and (b) average annual urban growth rate. Name and explain the salience of six characteristics of world or global cities. Does the prevalence of small cities mean that sustainable development is more likely than if we all lived in mega-cities? Justify your answer. Summarize the main objectives of Chapter 7 of Agenda 21. What does William McDonough have to say about biological and technical nutrients and how might these relate to sustainable development in urban spaces? A Woman Thinking

5. Learning Objectives Module 6 Lecture 1 KGA171 demonstrate knowledge of geographical concepts, earth and social systems and spatial patterns of change create and interpret basic maps, graphs and field data identify and analyse different viewpoints to contribute to debates about global development communicate in reflective and academic writing, referencing literature when needed • be able to • explain why vulnerability is a key ‘emotional geography’ among human beings, especially in the face of natural hazards • name, describe and exemplify a range of natural hazards • name, describe and explain a range of management responses to hazards

What key questions or problems does the author raise? What information, data and evidence does the author present? What key concepts does the author use to organize this information, this evidence? What key conclusions is the author coming to? Are those conclusions justified? What are the author’s primary assumptions? What viewpoints is the author writing from? What are the implications of the author’s reasoning? [from Foundation for Critical Thinking] Old Woman Reading a Lectionary, Gerard Dou

7. Part 2 Types of geo-hazards

8. Geo-hazards in specific environments • Fluvial environments – erosion, sediment accumulation • Coastal environments – storm surges, sea-level rise, inundation, erosion • Aeolian environments – wind erosion, dust storms, desertification • Periglacial environments – avalanches, thermokarst • Glacial environments – glacier outburst floods, surges • Karst environments – sinkhole flooding, hidden cover collapse
