GEOGRAPHY: The Human 'footprint'
Transcript of GEOGRAPHY: The Human 'footprint'
What is urbanisation?
As our population is growing rapidly around the world, there is no longer enough space in the cities alone. Because of this people are now living in the suburban areas of a city, most having moved from rural areas. This outward expansion of cities is known as URBANISATION.
In 2007, the United Nations revealed that at least 50 percent of the world’s population is living in cities. By 2030, that number will jump to 60 percent, with nearly 2 billion new city residents, many migrating from rural areas. According to the report, humans are building the equivalent of a city the size of Vancouver (3rd biggest city in Canada) every week.
Impacts of urbanisation on the environment
Natural or living (Biotic) Features of the environment;
Urbanisation has had many negative consequences on the natural or living (biotic) features of the environment:
Clearing of land that reduces biodiversity
Extinction and endangerment of animals, plants and aquatic life
Non-living (Abiotic) features of the environment;
Many non-living (abiotic) features of our environment have also become negatively affected due to urbanisation. In fact Urbanisation has been one of the leading factors in one of the most significant environmental events of our time...
Together with the effects of climate change urbanisation has resulted in;
Rise of global temperature of 0.7 degrees in the past 100 years
Poor Water Quality
Implications of this impact on society
Most of these large cities are in less developed countries such as India, China, Indonesia and Russia. In 1950 approximately half of these countries were in less developed regions, in 2010 however it is approximately two thirds. These statistics clearly show the increase in population and urban cities within less developed regions over time.
Urban population by major regions in per cent of total urban population
What is a solution to Sustainability and Urbanisation?
Working together towards a greener future
Sustainability is also another important solution to minimising impacts of urbanisation. It will help us reduce our 'carbon footprint', provide a healthier and sustained future and ensure we do not waste and run out of our precious resources.
The End :)
Do you have any...
1. Create a CAUSE and EFFECT diagram in your books like the one here
2. fill out the effects as you watch the following clip.

1) List the top 4 things you like about where you live in order of importance in a diagram like
2) Why do you like these things so much?
Urban Areas & Livability
Cities and large towns are centres of ECONOMIC ACTIVITY where people work to produce GOODS, SERVICES and INFORMATION.
Urban areas attract many people because of their LIVEABILITY.
Can you think of the things in your suburb (together with your top 4) that improve the LIVABILITY?

TREE of URBAN LIVABILITY
in your books and then add the factors for livability listed below in the tree format shown beneath in order of most important at the base of the tree and least important in the 'foliage' (leaves):
employment in the production of goods,
services and information >>> earn income;
health and recreation services;
education & community facilities;
sense of community, opportunity to develop social activities & relationships
The TREE of URBAN LIVABILITY
Resource Inputs & Waste Outputs in Sydney in 2010
3. 65 million tonnes
3. 84 million m3
659 million tonnes
418 billion MJ
33 million tonnes
(97% carbon dioxide)
2. 83 million tonnes
What are the main forms of waste here?
Select 2 of these wastes and discuss how they affect the physical environment.
Where do you stand on your EcoFootPrint?
Where do you stand on your EcoFootprint? cont.
Where do you stand on your EcoFootPrint?
PART 1 (VIDEOS i. and ii.) - As you watch the viseos in PART 1:
a.define what you think
might be from the information you view. And, note 1 or 2 examples for each given in the video
add terms to glossary
b.Give and discuss an example of each term in your own life in class discussion
PART 2 (VIDEOS iii. and iv.) - As you watch the EcoFootprint videos:
a. Complete the RETRIEVAL CHARTS for the two clips (expectations are with videos).
b. Then,complete a 3:2:1:R:I:Q and discuss/share in a class discussion your recollections, insights and questions.
i. What is Consumerism?: The Story of Consumerism
ii. National Geographic: The Human Footprint
The Bio-Diversity Code
Watch the clip, then explain in your glossary what 'BIODIVERSITY' is and why its important
Under the above heading, categorise and list some effects of urbanisation in a T-Chart (from the up-coming 'zooms)
Biotic (natural features)
Abiotic (non-living features)
According to Greenpeace, how is land clearing impacting on biodiversity in Indonesia?
What can we learn from these statistics and those that follow in comparison? Consider the Trends
ACTIVITY: Noisy Round Robin
1) Note down in a table the ABIOTIC and BIOTIC features effected by climate change in the three countries shown here: Nepal ; Ethiopia ; Peru
2) Evaluate to what extent each country was affected by CLIMATE CHANGE in an extent barometer for each country, then explain which is most affected and why
According to Professor Rosling,
1) What are the trends presented here?
2) What is his prediction for the future?
3) Can we believe this information? Why?
Find 'Gapminder' online and,
1) Identify a topic of interest relating to Urbanisation, World Health, or Sustainability (the environment)
2) Investigate the topic and note the data:TRENDS and Predictions
3) Prepare to report back to class on your topic
- Identified and found information on an interesting topic in GAPMINDER
- Investigated the trends on that topic from the data in GAPMINDER
- Able to present to class the trends or future predictions on your chosen topic explaining the significant periods of CHANGE or CONTINUITY
Let's evaluate which presentation hits the SUCCESS CRITERIA most. We will do this via a 'tournament challenge':
5 points each
Peer assess each stage and justify each selection for progression
Working with statistics
RETRIEVAL CHART INFORMATION FOR VIDEO iii.:
as you watch, you will notice and note 3x in-depth explanations and 6x recommendations (hint:shoes, fashion and electronics)
To understanding the key terms CONSUMERISM and CONSUMPTION and how these terms relate to our eco-footprint.
RETRIEVAL CHART INFORMATION FOR VIDEO iv.:
as you watch, you will notice and note 3x in-depth explanations (hint: plastic bottles; batteries; wrapping), approximately 7 statistics and 7x recommendations
based on living organisms. These are obtained from the biosphere. Examples are animals, birds, forests. They can reproduce themselves
based on non-living organisms. They are obtained from lithosphere, atmosphere and hydrosphare. Examples are water, air, minerals. They cannot reproduce themselves.
Definitions... add to your glossary!
What might 'consumption' & 'consumerism' be?
