Water Scarcity
(VCGGK108)
- Investigating the causes of water scarcity. For example, an absolute shortage of water (physical), inadequate development of water resources (economics), or the way water is used.
- Comparing the effectiveness in reducing water scarcity of methods that increase the supply of water (such as recycling waste water, stormwater harvesting and re-use, desalination and inter-regional transfer of water) with methods that reduce the demand for water (such as pricing, changing the use of water and water restrictions).
- Examining why water is a difficult resource to manage. For example, difficulties in accounting for its economic value, its competing uses and variability of supply over time and space.
- Explaining why some land use management practices such as land cleaning and some farming practices have adversely affected water supply.

Concepts and Skills
Place
Explain processes that influence the characteristics of places VCGGC099
- Explaining the physical causes and the temporal and spatial patterns of an atmospheric or hydrological hazard through a study of either droughts, storms, tropical cyclones or floods.
- Exploring the geomorphology of the land and how this affects the liveability of a place.
- Contrasting the effects of geomorphic processes that lower the land surface (weathering and erosion) and those that raise the land surface (transportation and deposition).
- Discussing urbanisation as a shift in where, how and why people live where they do.
-
Space
Identify, analyse and explain spatial distributions and patterns and identify and explain their implications VCGGC100
- Interpreting the spatial distribution of rainfall in Australia and comparing it with that of other continents.
- Comparing accessibility to and availability of a range of services and facilities between different types of settlements (urban, rural and remote) in Australia and other countries. For example, shops, access to clean water, sanitation, education and health services.
- Investigating the natural causes and spatial distribution of a geomorphological hazard. For example, volcanic eruptions, earthquakes, tsunamis, landslides and avalanches.
- Exploring the arguments for and against a more balanced distribution of the urban population.
-
Interconnection
Identify, analyse and explain interconnections within places and between places and identify and explain changes resulting from these interconnections VCGGC101
- Describing how water is an available resource when it is groundwater, soil moisture (green water), and surface water in dams, rivers and lakes (blue water), and a potential resource when it exists as salt water, ice, water vapour or waste water, and using the concept of the water cycle to show the connections between the different forms.
- Explaining how the movement of water through the environment connects places. For example, the melting of snow in spring feeding rivers and dams downstream.
- Comparing student access to and use of places and spaces in their local area and evaluating how this affects perceptions of liveability.
- Analysing the role of landforms and landscapes in tourism. For example, Uluru in Australia or the Grand Canyon in the USA.
- Examining how urbanisation can affect environmental quality and analysing the effects of erosion and sedimentation produced by human activities on landscape quality.

Analysis
Analyse maps and other geographical data and information using digital and spatial technologies as appropriate, to develop identifications, descriptions, explanations and conclusions that use geographical terminology (VCGGC104)
- Using aerial images of contrasting places to identify differences in housing density.
- Using graphs, weather maps and satellite images to examine the temporal and spatial patterns of a selected hydrological hazard in Australia and another region of the world, such as countries of the Asia region, or from the Pacific region.
- Using digital maps and overlays of an area to observe, describe and contrast the spatial associations of geographical phenomena. For example, the relationship between economic activities and river systems and the availability of surface water.
- Interpreting topographic maps and digital terrain models, cross-sections or block diagrams to investigate landforms and their features.
- Reviewing the results of an analysis to propose and defend answers to a question, emphasising at least one of the geographical concepts of place, space, environment, interconnection, sustainability, scale or change.
