The challenges of an urban world PEOPLE AND THE PLANET The challenges of an urban world TOPIC 7 7.2 How can these challenges be managed? 7.2a Cities in the DEVELOPED world have huge potential to reduce their environmental impact (ECO- FOOTPRINTs)

starter Title- Why do ECO- FOOTPRINTS vary from place to place? Lesson 5- Today we will INVESTIGATE why ECO-FOOTPRINTS vary from city to city and ASSESS how one city in the DEVELOPED WORLD is reducing its ECO-FOOTPRINT. starter Look at the image of a city on the board. What things are needed for that city to function (INPUTS and OUTPUTS)? Title- Why do ECO- FOOTPRINTS vary from place to place?

Visual pollution Air pollution Resources run out Now imagine the problems that will be created if you place a dome over the entire city Visual pollution Air pollution Resources run out

What SECONDARY problems will be created Air pollution What SECONDARY problems will be created Health issues- asthma and bronchial problems increase Costs of treating these people increases- Strain on budgets

What SECONDARY problems will be created Visual pollution What SECONDARY problems will be created Build up of waste Leads to increase in rats and other pests Increases disease risk

What SECONDARY problems will be created Resources run out What SECONDARY problems will be created Services will cease City will cease to be able to function

Once we use the land and water and other resources that is it The Earth is isolated in space, it has limited land and water (finite) and thus limited resources we can use- Like a domed city- Once we use the land and water and other resources that is it Ecological footprint = measure the amount of land that would be needed to support people’s lifestyles and dispose of the pollution and waste created. They are a useful way of calculating the impact of people’s lifestyles on the environment.

Exam skills practice HIGHER- Describe the distribution of countries with a high ECO- FOOTPRINT (2) FOUNDATION- Which statement is true? Countries with a high ECO- FOOTPRINT are mainly found in Africa and Asia Countries with a low ECO- FOOTPRINT are found mainly in Africa and Asia

How is London Reducing its ECO- FOOTPRINT? ASSESS how one city in the DEVELOPED WORLD is reducing its ECO-FOOTPRINT. How is London Reducing its ECO- FOOTPRINT?

1) What does the ECO- FOOTPRINT of a city look at? One way of measuring the impact we have on the environment is an ‘ecological footprint’ (eco-footprint). The eco-footprint of a city looks at how much land is needed to provide it with all the energy, water and materials it uses. The footprint calculates how much pollution is created by burning oil, coal and gas, and it works out how much land is needed to absorb the waste created by the people of the city. The purpose is to work out how sustainable any city is and especially what changes we need to make to improve the quality of life for people now and in the future. 1) What does the ECO- FOOTPRINT of a city look at? 2) What does an ECO- FOOTPRINT calculate about pollution? 3) What is the purpose of working out an ECO- FOOTPRINT?

The UK average is 5.3 ha (hectares) per person. Eco-footprints are expressed in terms of how much land is needed to support the lifestyle of the people and to deal with the pollution and waste they create. The UK average is 5.3 ha (hectares) per person. This average varies from place to place. E.g. towns in the countryside generally have a lower eco-footprint than towns close to other cities. This is because they may produce more of their own food (and possibly power) and they may generate less waste. 1) How is an ECO- FOOTPRINT expressed? 2) What is the average ECO- FOOTPRINT of someone in the UK? 3) Why does an ECO-FOOTPRINT vary from place to place?
