POPULATION THEORY

• Thomas Malthus

THEORIES ON POPULATION

• Thomas Malthus
• Esther Boserup

LEARNING OBJECTIVES

• Describe the population theory proposed by Thomas Malthus.
• Evaluate whether or not you think his theory is correct and prioritize your arguments.
• Make future predictions linking resources and population growth.

Key Terms

• Optimum population: Achieved when the number of people working with available resources produces the highest economic return and standard of living.
• Overpopulation: An undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Ask: What might cause overpopulation to occur?

Thomas Malthus Research Task!

• Use your laptop to research and complete the questions in the handout provided.

So…Was Thomas Malthus Right?

• The human population has continued to grow long past Malthus’s predictions. So what happened? Why didn’t we die off?
  1. Technological increases in food production have increased both the amount and quality of calories we can produce per person.
  2. Human ingenuity has developed new medicine to curtail death from disease.
  3. The development and widespread use of contraception and other forms of family planning have decreased the speed at which our population increases.

So…Was Thomas Malthus Right?

• Of these three proposed reasons, which do you believe is the most SIGNIFICANT REASON that the population of Earth has continued to grow. Explain your reasoning in at least two, correctly structured, paragraphs.
  1. First, technological increases in food production have increased both the amount and quality of calories we can produce per person.
  2. Second, human ingenuity has developed new medicine to curtail death from disease.
  3. Thirdly, the development and widespread use of contraception and other forms of family planning have decreased the speed at which our population increases.

But What About the Future?

• 'Some still believe Malthus was correct and that the ample resources to support the earth’s population will soon run out.'
• Respond to this statement by stating whether or not you agree and justifying why/why not.
• At least one paragraph is required here!

POPULATION THEORY

• Ester Boserup

LEARNING OBJECTIVES

• Describe the population theory proposed by Esther Boserup.
• Compare her key arguments with those of Thomas Malthus.

Recap

• Last lesson we examined the population theory proposed by Thomas Malthus.
• With the person next to you recap the key focus of his theory and write it down in a sentence.

Recap

• Malthus‘s theory was based on the assumption that the power of population is much greater than the power of the earth to provide subsistence for man.
• Malthus believed that the population would soon surpass its food supply.
• This, in his belief, could only lead to disease, high infant mortality, famine, starvation, and war (positive checks).

Ester Boserup

• Ester Boserup (1910–1999) was a Danish economist who specialised in the economics and development of agriculture.
• She opposed Malthus’s views on the matter of population and held a more optimistic approach to the issue of population growth.

Ester Boserup - Key Points

• When population growth finds us pressed for food, people find ways to get more food production out of the land.
  • Eg: they cultivate the land more intensively. They invent their way out of the Malthusian crisis.
• The Malthusian trap may even have driven the development of technology.
• She believed that a growth in population would stimulate a growth in agriculture and technology.

Boserup

• Population Increase -> Increased Demand for Food -> Agricultural Productivity Improved -> More Food Produced -> Population Growth Continues
• In your notebooks, draw a graph to illustrate Boserup’s theory

Comparison Continued

• If Boserup was right, then wouldn’t the most technologically advanced places be the ones closest to a Malthusian crisis. Is this what we see in the world today? Explain your answer.
• If Malthus was right, places with large populations that are still increasing, will eventually surpass their food supply and become famine and war stricken. Or would have already done so. Is this what we see in the world today? Explain your answer.

• Read the pages on Application of Malthus and Boserup on Google Classroom and respond to the questions.

Environmentalists vs. Economists

• Comparison of views on people, resources, and population growth with examples.
  | | Proponent | View of people and resources | View of population growth | Example of belief |
  | :-------------------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | |
  | Economists view | Professor Julian Simon, University of Maryland, USA | People are the ultimate resource not the problem, every newly born human is a fresh source of ingenuity who can provide many more solutions to problems than they can ever cause | Population growth is responsible for technical improvements in social structures e.g. transport and communication, which sustain further high population growth | Energy provision is one of the global problems of the 21st century: Simon sees future generations as the discoverers of new forms of much-needed energy |
  | Environmentalists view | Paul Ehrlich, neo-Malthusians | People are condemned to live in poverty and hunger because of food shortages, lack of development and limited resources, natural environments can only support a limited population | People always reproduce faster than food supplied will increase | Deforestation, global warming, desertification, depletion of the ozone layer, wars and disease are all signs of impending Malthusian Crisis |

Research Questions

• Can you find an example of an individual or a group that thinks Malthus was right? What are their arguments?
• Food is not the only resource that we need to survive. Can you think of other resources that humans compete for? What would happen if they ran out?

Advantages and Disadvantages of Migration

• Migration between countries in the EU helps to halt population decline, but creates advantages and disadvantages for both origin and destination countries.

• Sort these into economic advantages and disadvantages and social advantages and disadvantages.

• What conclusions can you draw from your table? For example, are the advantages and disadvantages for
  the country of origin mainly social, economic or a combination of the two? Do the advantages outweigh the
  disadvantages for both countries or is one losing out?

• The UK government has said that it will hold a referendum in 2017, if it is re-elected, which will ask the
  public whether or not the UK should remain a member of the EU. You can read more about this at
  http://www.bbc.co.uk/news/uk-politics-25152028.

• Purely thinking about the issue of migration, do you think that not being a member of the EU would make
  the population situation in the UK better or worse? Why do you think this?

2 Migration Case Studies

• Case Study: Transmigration in Indonesia
  • Indonesia, made up of a collection of 13677 islands over 3000 miles long, is found in the South China Sea to the north of Australia (see Fig 1).
  • It has an equatorial climate and most of the islands are covered by Tropical Rainforest vegetation.
• The scheme offers:
  • free transport to the new area.
  • free land allocation of two hectares.
  • free housing in the new area.
  • free equipment, fertilisers etc. and enough food to keep the family going until the first harvest.
• There have been several issues associated with transmigration in recent years:
  • It is very costly and over £200 million has been loaned by the World Bank so far to help with the scheme. Many people feel that its limited success does not justify this spending. Its impact on Indonesia’s population problems has been minimal. In the 1980s, Java’s population increased by 18% in spite of out-movements. In 1995 the country’s population was growing by 3.2 million per year! This is more than the entire number of people who had moved out from the core in the whole of the transmigration movement. Also, up to 20% of the migrants have since returned home because of problems in the new areas.
  • Many people are alarmed at the effects on the environment. Over 120 million hectares of Tropical Rainforest have been felled to create land for the new settlers. Soil erosion and soil exhaustion also occurred once the delicate balance of the Tropical Rainforest ecosystem has been disturbed.
  • There have been conflicts between the immigrants and the local residents because: (i) Traditional farmers are worried that the incomers will take over their area and destroy their way of life. They also complain that the new settlers are given more financial help than they receive. (ii) Local shifting cultivators have had to move as their land is being used by the newcomers.
• However, transmigration has brought some advantages.
  • Improved infrastructure on the peripheral islands, e.g. better roads, more schools and health facilities, although in many areas they are still not adequate for the numbers of people who actually live there.
  • People from the core who had no land or jobs now have a future in their new homes.
  • Some spontaneous migration to the outer islands has been stimulated.
• In the future, transmigration policy will probably focus on providing rural infrastructure to attract people and encourage migration and less on large- scale organised schemes. It may be better for the country to try to solve the problems linked with its rapid population growth by more family planning programmes, intensifying agricultural production, developing the country’s plentiful oil and gas reserves and industries, rather than by organised transmigration.

3 Migration Case Studies

• Case Study: Vietnamese Boat People
  • The Vietnamese war (1957 to 1975) was a conflict between the people of South Vietnam, supported by the USA and capitalist countries, and those of the north supported by the USSR and communist countries. In 1975, the communists overran Vietnam, and one of the largest mass- migrations of all time started from south Vietnam. Since then two million refugees have migrated to settle in over twenty five different countries.
  • Most of these people moved by sea and so were termed ‘boat people’.
  • It was not cheap to leave on a boat and many of them were the richer professionals who could afford to pay. Some of the boat people, in their very overcrowded vessels, were picked up by foreign ships. Others landed in nearby south east Asian countries such as Malaysia, Thailand and Hong Kong, where they were housed in refugee camps whilst awaiting a decision on their future. Many then moved to live in East ern Europe, Middle Eastern countries, the USA, China, Canada, Australia and the UK. (see Fig 3).
  • However, since 1979, more and more of those leaving have been lower and middle class ethnic Vietnamese. These ‘economic migrants’ wanted a better way of life than the traditional farming economy at home. Conditions in Vietnam were worsened by natural disasters such as in the early 1980s there were several typhoons and food shortages. It has been said that the first migrants were pushed but later ones were pulled!
  • In 1989 there was an international meeting in Geneva to plan the future of these Vietnamese refugees. It was suggested that future emigrants should be screened as to the exact reason for wanting to leave their country and only true refugees should be allowed to leave.
  • Several suggestions have been made on what should happen to the refugees who are still in over-crowded camps in various south east Asian countries such as Hong Kong.
  • A. Forcible Repatriation: Vietnamese in Hong Kong who do not have true political status are being told that they must return home. In 1989, shortly after the Geneva meeting, there were negotiations for the forcible repatriation of some of the economic migrants but there were many international objections to such measures. There was one airlift of 51 people in December 1989 and also voluntary repatriation of about 2000 people. These measures acted as a short-term deterrent and immigration figures went down, but increased again when the immigrants thought that mandatory repatriation was not going to occur on a large-scale. By the early 1990s boatloads of illegal emigrants were once again reaching other south east Asian countries and being towed back out to sea.
  • B. Improve conditions in Vietnam: Some people would be happy to return home if they felt that their futures were secure. The government is trying to attract people, especially some of the more educated classes, that are vital to the economy, by offering financial incentives such as doubling their incomes.
  • C. Other countries could accept more immigrants. Unfortunately, many MEDCs a re suffering from what has been termed ‘compassion fatigue’ due to constant requests for help from all over the world.
• Once living in these countries the immigrants often suffered from various problems as they had been subsistence rice-farmers at home. They often did not have the necessary job skills for the new countries and were unused to their climates and customs.
  • The first wave of around half a million migrants were political refugees. Many feared for their lives, especially those who had been active in the war, under the new regime. They were subjected to:
    • political persecution from the communist government.
    • a clampdown on capitalist activities
    • racial persecution, as the new government had a poor relationship with China which affected the large ethnic Chinese community in Vietnam.

Challenges to Policy Making

• Research and Define (in your own words) each of the following challenges to policy making when it comes to making decisions for/about the environment
  • Political Resistance & Partisan Divides
    • Environmental policies often become politically charged, with disagreements over the role of government in regulation.
    • Some policymakers may resist stricter environmental laws due to concerns about government overreach or ideological opposition to climate policies.
  • Economic Interests & Industry Opposition
    • Industries like fossil fuels, agriculture, and manufacturing often lobby against policies that could increase costs or require major operational changes.
    • Short-term economic concerns, such as job losses in polluting industries, can outweigh long-term environmental benefits in political debates.
  • Lobbying & Corporate Influence
    • Large corporations and industry groups invest heavily in lobbying to influence legislation in their favor.
    • Fossil fuel companies, in particular, have historically pushed back against climate regulations and renewable energy policies.
  • Public Awareness & Misinformation
    • The complexity of environmental issues can lead to confusion or misinformation, making it difficult to build public support.
    • Some groups spread climate change denial or downplay the severity of environmental problems.
  • Short-Term Thinking vs. Long-Term Benefits
    • Politicians often focus on short-term election cycles, while many environmental policies require long-term planning and investment.
    • Immediate economic or social trade-offs (e.g., higher energy prices) can make it harder to pass ambitious policies
  • International Coordination Challenges
    • Environmental problems like climate change and pollution are global issues that require international cooperation.
    • Some countries may be reluctant to commit to environmental policies if they believe others won’t do their part.
  • Legal Challenges & Bureaucracy
    • Environmental policies often face legal battles from businesses or interest groups that claim new regulations are unconstitutional or harmful to their industry.
    • Regulatory agencies may be slow to implement changes due to complex bureaucratic processes.
  • Balancing Economic Growth & Sustainability
    • Policymakers must balance environmental goals with economic growth, which can create tension in areas like resource extraction, energy production, and land development.
  • Resistance from the Public
    • People may oppose policies that increase taxes, energy costs, or regulations on everyday activities (e.g., gas-powered vehicle bans).
    • There can be resistance to lifestyle changes required by environmental policies, such as reducing meat consumption or switching to renewable energy.
  • Scientific Uncertainty & Complexity
    • While climate science is well-established, some environmental policies rely on complex models and projections that may be contested.
    • Uncertainty about the exact impact of certain policies can be used as an argument against action.

Worldviews

• People hold different world views about the environment depending on what is valuable to them…
  • A commodity view of the environment suggests that land can be owned and traded freely, and that such trade puts property to its greatest use.
  • The productivity view of the environment is about putting environmental resources to use for the betterment of society and to enable profit to be generated by industry.
  • A spiritual view of the environment suggests a deep personal connection to the environment, a sense of place and a feeling of responsibility towards it.

Worldviews

• An ecological view of the environment places value on biodiversity, ecological processes and natural cycles.
• A community view emphasises public access to the environment and the right of everyone to enjoy it freely for social interaction and recreation.
• The landscape view of the environment usually involves a holistic understanding of the visible features of an area of land - including cultural values.
• A sustainability worldview seeks to combine rather than trade off ecological, cultural, social and economic values.

Influence of People's Perspectives…

Perspectives

• There are many different perspectives when discussing the management of the environment.
  • Ecocentrism: places a focus on nature rather than humans. Ecocentrism proposes that we should consider humans as part of the biotic community and that we should modify our behaviour to protect the ecosystems to which we also belong.
  • Biocentrism: endorses ethical treatment of all living things. Biocentrics consider that humans are not superior to other species.
  • Anthropocentrism: places a focus on meeting human needs and recognises humans as the dominant species on Earth. Ecocentrics consider this ideology to be the cause of unsustainable development.
  • Technocentrism: proposes that environmental problems can be solved using science and technology.

Global Warming and the Greenhouse Effect

• One of the main waste gases emitted by burning fossil fuels is carbon dioxide $(CO<em>2)$. \CO2 is also one of several greenhouse gases. These are important for trapping some of the sun's heat in our atmosphere and so maintaining temperatures. Without this greenhouse effect, temperatures on earth would fall at least $30 ^\circ C$ and so life could not exist.
• However, an accumulation of greenhouse gases is also harmful to life. This is because the more gases there are in the atmosphere, the more heat is trapped at the earth's surface. Scientists blame the large-scale consumption of fossil fuels, especially by the developed industrial nations, for the increasing \CO2 in the atmosphere. In turn, scientists consider this \CO2 to be responsible for global warming, or raising the temperature of the earth's atmosphere. There are national and regional variations in carbon dioxide emissions.
• Scientists blame the large-scale consumption of fossil fuels, especially by the developed industrial nations (Fig. 7.20), for the increasing \CO2 in the atmosphere. In turn, scientists consider this \CO2 to be responsible for global warming, or raising the temperature of the earth's atmosphere. There are national and regional variations in carbon dioxide emissions.
• Approximate relative greenhouse effect per molecule:
  • Carbon dioxide ($CO_2$): 1
  • Methane ($CH_4$): 20
  • Nitrous oxide ($N_2O$): 290
  • Chlorofluorocarbons (CFCs): 3,500 - 7,300

Green Economics

• While much of the cause and effects of pollution are seen in the developed North, there is a need for international co-operation. Some pollution-control economists suggest tradable emission quotas for each country
• In June 1997, at an Earth Summit in New York, representatives of 160 countries expressed concern at the continuing deterioration of the environment.

Petroleum Exploration and the Environment, Nigeria

• Oil was first discovered in Nigeria in the late 1950s. Ever since, it has been the major source of foreign exchange for this country.

• The environmental costs of producing oil have been enormous especially to the local communities.

• Shell Characteristics:

  • Shell, an Anglo-Dutch oil company, is one of the world's largest oil TNCs in the Niger Delta.
  • Shell oil company accounts for over
    50 per cent of Nigeria's daily oil production.
  • Found oil in Rivers state in 1958
  • established six oil fields in this highly productive agricultural area.

• The Ogonis:

  • The Ogoni region is one of the most densely populated areas in Africa
  • The Ogoni people, who have lived in this fertile area for centuries, depended on fishing and farming for their livelihood

• Effects of Oil exploration:

  • Since 1958, farmers in Ogoni have had to compete with oil companies operating in their area causing valuable land to be lost.
  • Oil spillage has been frequent with serious environmental and health consequences for the local community
  • The Nigerian Ministry of Petroleum attributes most spills to equipment failures and corrosion

Globalisation

• LEARNING OBJECTIVES
• Understanding what globalisation means.
• Analyse the impact it has on our lives.

WHAT DO YOU THINK?

• Think on your own (5 minutes) What do you know about Globalisation?
• How has it improved your lives (positives/negatives)?
• What do you think of when you hear the word globalisation?
• How has it affected my community?

Economic Globalisation and Migration

• Labour Mobility: Economic globalization has created international job markets, leading to the movement of people seeking better employment opportunities.
  • For example, many migrate from developing countries to industrialized nations in search of higher wages and improved living conditions.

Globalisation and Migration

• Transnational Corporations: Global businesses often relocate operations or create branches in multiple countries, prompting the movement of both skilled and unskilled workers across borders.
• Remittances: Migrants contribute to globalization through remittances, sending money to their home countries, which integrates local economies into global financial systems.

Cultural Globalization and Social Migration

• Cultural Exchange: The spread of ideas, languages, and lifestyles through globalization makes new destinations more appealing and culturally accessible to migrants.
• Education: International educational opportunities, facilitated by globalization, encourage students to move abroad for higher learning, leading to long-term migration or the creation of transnational communities.
• Technology: Advances in communication and transportation, key elements of globalization, make migration easier and more feasible.

Political Globalization and Refugee Movements

• Global Governance: International agreements and organizations (e.g., the UN or the EU) influence migration policies, enabling or restricting movement.
• Conflict and Stability: While globalization can promote economic growth, it can also exacerbate inequalities or contribute to instability, prompting forced migration due to conflict, climate change, or economic hardship.

Global Networks and Diasporas

• Migrant communities often maintain strong transnational ties, facilitating further movement of people and goods. These diasporas become crucial nodes in global networks of trade, culture, and information exchange.

Challenges and Debates

• Economic Disparities: While globalization facilitates migration, it can also deepen inequalities, creating tensions in host countries over resources and jobs.
• Brain Drain vs. Brain Gain: Migration spurred by globalization can lead to a loss of skilled workers in some regions while benefiting others.
• Sociopolitical Tensions: The movement of people sometimes leads to cultural friction and debates over immigration policies.

Globalisation I

Ecosystem

• An ecosystem is a region with a specific and recognizable landscape form such as forest, grassland, desert, wetland or coastal area.
• The nature of the ecosystem is based on its geographical features such as hills, mountains, plains, rivers, lakes, coastal areas or islands.
• It is also controlled by climatic conditions such as the amount of sunlight, the temperature and the rainfall in the region.
• The geographical, climatic and soil characteristics form the non-living (abiotic) component. These features create conditions that support a community of plants and animals that evolution has produced to live in these specific conditions.
• The living part of the ecosystem is referred to as its biotic component.

Components

• Ecosystems are divided into subsystems:
• Biotic (living elements)
  • Producers - plants
