What do the UN predict about the future?

The greenhouse effect— A natural process which keeps the Earth warm. Greenhouse gases in the atmosphere act as a blanket and trap solar radiation that is being radiated back out to spade from Earth. Without this the Earth would be much cooler. The enhanced greenhouse effect—Human activity has increased the amount of greenhouse gases being released into the atmosphere. This means the Earth absorbs more solar radiation and as a result is becoming warmer. Human activities— Energy—The demand for energy is increasing as the population increases, standard of living improves, technology improves and people become more affluent. Industry—As people have more disposable income increases so does the demand for products from consumers leading to industrial growth. This leads to more fossil fuels being used. Transport—As cars are becoming more affordable more people are buying and using them. As well as this, flights are now cheaper so people fly more. All modes of transport rely on fossil fuels at present. Farming—As the population has grew the need for more food has increased leading to more intensive agricultural practices that require machinery.

High Winds

Intense Rainfall

Storm surges

Coastal Flooding

Landslides

How are tropical storms formed?

Intensity of Tropical Cyclones Tropical cyclones need warm water to form, they also need the Coriolis effect for them to rotate hence they are not located at the Equator. As well as this they need—

High humidity– there must be a lot of moisture in the atmosphere.

Rapid cooling– rising air must condense quickly to form the rainbands

Low wind shear– if winds are blowing in different directions in the atmosphere a cyclone cannot form.

Pre-existing low pressure– for the air to rise and generate a storm.

Vulnerability to cyclones Coastal areas

Low lying land

Social Vulnerability

Social inequality (poverty)

Age

Economic Vulnerability

.

Where are they located?

What are the Hazards of Tropical Storms?

How do we measure cyclones?

The impacts of tropical cyclones are linked to a country’s ability to prepare and respond to them Preparing depends on accurate forecasting and effective communication to people at risk. Ways of preparing:

Atmospheric Pressure

Satellite tracking and radar.

Modelling

Communicating information

How can the responding to Tropical Cyclones prevent damage?

Response refers to how people deal

CASE STUDY—Hurricane Katrina, USA (Developed country), 2005 29/08/2005, Hurricane Katrina a category 3 hurricane, made landfall on the South coast of the USA. Preparing Response

CASE STUDY—Typhoon Haiyan, Philippines (Emerging country), 2013 2/11/2013— Typhoon Haiyan was the strongest tropical cyclones on record which was a category 5 on the Saffir-Simpson Scale Preparation Response –.

Developed—e.g. London and Paris

Emerging—e.g. Mexico City and Mumbai

Features Formal Employment (E.g. Industry—car manufacturer)

Informal Employment (E.g. street seller)

Scale of activity

Large scale—Usually in a factory Small scale– maybe on a street corner

Level of skill

High level skilled work Low level skills

Ease of entry

Needs a lot of funding and equipment to get started.

Needs little funding or equipment to start

Need of capital

Needs a lot of capital to get started and is often funded by governments

Needs little capital to start

Number of workers

Often more than 100 workers Usually a few workers who are generally unemployed

Working conditions

Workers have protection to ensure the environment is safe e.g. accident prevention policies. Usually there are set working hours and some have trade unions to ensure good working conditions.

No protection for workers. No set working hours, may have to pay protection to gangs. There are no trade unions to support workers.

Location Factories Home or on the street

Taxes Pay tax to the government Pay no taxes

Formal and Informal economy

The impact of migration on urbanisation— National migration International migration

Impact of economic change on urbanisation Growth of cities— Decline of Cities

Differences in Urban Economies The developed, emerging and developing countries are at different stages of economic development, which is reflected in their urban economies. The Clark-Fisher model of changing employment helps us determine the stage of economic development of a country. These stages are:

Pre –industrial

Industrial

Post-industrial

Later stage

Cities change overtime and this is reflected in changing land use (How population, distribution changes overtime, characteristics of urban areas)

The number of people living in a city, where they live within the city and how the city shapes itself all change over time. A city may go through each of the following stages:

Urbanisation— .

Suburbanisation

De-industrialisation

Counter-urbanisation

Regeneration

Reurbanisation.

Factors influencing land use:

Accessibility.

Availability

Cost

Planning Regulation

Similarities and differences between developed, developing and emerging countries:

Similarities:

Differences:

Urbanisation is a result of socio-economic processes and change. (migration, national, international, urban economies, type of employment)

Urbanisation is the process by which an increasing percentage of people live in towns and cities. It is mainly caused due to migration from rural areas. Urbanisation is more prominent in emerging and developing countries. By contrast the urban population in developed countries will grow less. Demographers make projections of what they think will happen in the future. Most agree that urban areas will increase and rural areas will decrease. Urbanisation in developed countries—The growth of urban areas in developed countries was a result of the industrial and agricultural revolutions in the 18th and 19th centuries. At this time people moved from rural areas to the urban areas to gain work in factories. Urbanisation has been slow and over a long period of time. It has remained steady in developed countries since the 1980s.
