4 Population Problems in LEDCs Lesson Objectives Explain Malthus theory of population growth Describe the problems associated with population growth in LEDCs Identify some of the problems faced in Nigeria

5 Which is the right pyramid? Which population pyramid do you think is from an LEDC?

6 Fill in the gaps Population are very in LEDCs and MEDCs; in fact they are opposite. LEDCs are countries which are trying to provide for and populations which have resulted from many years of and consistent population growth. Where as MEDCs are having to come to terms with an population and fewer people of age. Ageing, Different, Young, Problems, Growing, Rapid, Working

7 Why are there problems in LEDCs? Rapid rates of population growth in LEDCs have crippled many countries leading to a series of problems The results are low standards of living, poor quality of life and poverty; leading to an increased vulnerability to natural disasters But why is this happening? Is it natures way of keeping the population in check?

8 David Attenborough s take on it all

9 Malthus Theory Malthus believed that populations grew exponentially but that food production grew steadily With a partner discuss the following: what do you think his theory says? In 4 sentences explain Malthus theory and how it links to the problems of population growth

10 Problems of over-population in LEDCs On your piece of paper you must work as a table to come up with as many problems of population growth in LEDCs as you can think of Now try to categorise these into ECONOMIC, SOCIAL and ENVIRONMENTAL

11 Problems of rapid population growth ECONOMIC SOCIAL ENVIRONMENTAL Corrupt governments lead to high levels of debt Overcrowding of cities leading to the growth of shanty towns Overgrazing and over cultivation of rural areas High levels of unemployment Traffic congestion in cities Water, land and air pollution Desertification means that farmers crops fail, loosing money Lack of money for basic services Deforestation and desertification Poor healthcare and schooling Shortage of raw materials and resources Rising levels of crime Shanty towns result in the destruction of green spaces Low standards of living

12 What problems can you identify?

13 NIGER, AFRICA Rapid Population Growth (LEDC)

14 Where is Niger? On your map of Africa shade and label where Niger is Then describe its location within Africa think about the equator is it near the Sahara is it in the north, south, east, west etc

15 Describe the location of Niger Neighbouring countries, rivers, capital, borders

16 Where is it? Total Population million Population Growth Rate - 2.9% Life Expectancy years Literacy Rate % GDP per capita - $700 Population below the poverty line - 63%

17 Compare Niger and the UK s level of development Total Population million Population Growth Rate - 2.9% Life Expectancy years Literacy Rate % GDP per capita - $700 Population below the poverty line - 63% Total Population million Population Growth Rate - 0.6% Life Expectancy years Literacy Rate - 99% GDP per capita - $ Population below the poverty line - 14%

18 Niger - an LEDC Land locked country in West Africa, named after the Niger river which flows through it It is very hot and dry, with many desert areas It is one of the poorest countries in the world The population of Niger has grown from 1.7million in 1960 to over 13 million in 2008 It is expected to reach 56 million by 2050 Niger has the highest fertility rate in the world at 7.1 births per woman Which means half the population is under 15

19 How is it growing? Using the handout on Niger complete the line graph to show birth rate and death rate in Niger (Task 3)

20 Niger s changing birth and death rates 60 Birth Rate Death Rate Birth and Death Rates in Niger 50 Rate (per 1000 people)

21 Why have many countries managed to tackle a high death rate? Working in a group, discuss the reasons why death rates have been reduced in many countries Put the reasons in order of importance and explain your opinion babies are inoculated against diseases there are better supplies of clean water people eat a better diet there are more clinics and hospitals people enjoy better living conditions women are becoming better educated

22 Niger - an LEDC Why do you think Niger could be facing so many problems to do with population?
