‘Social impacts refer to the effect of an event on the well-

being of people.’

Social Impacts

livesHomelessness Disruption to clean

‘Economic impacts refer to the effect of an event on goods and services being produced, sold and bought.’

Economic Impacts

Damage to machinery and equipment

Damage to transport infrastructure

Disruption to energy supply

Damage to machinery and equipment

Floods can damage machinery and equipment–Such as drilling machines, cranes and computers–Motors and other electrical components of machines and equipment can be damaged when submerged in water

Damage to machinery and equipment Example: The 2011 Thailand floods caused extensive

damage to the manufacturing industry

Machinery and

equipment damaged

by floodwater

s

Factories are

unable to operate at full

capacity and

suffer economic

losses

Companies may lose profits

and have to spend money to buy new equipment. People may also

lose their jobs.

 1055 new cars Honda will be scrapped

Damage to transport infrastructureDuring a flood, transport infrastructure may be submerged or damaged and become impassable

Repair of damaged infrastructure may take a long time, and may be costly

Disruption to energy supplyFloods can disrupt the supply of energy –During floods, roads may be damaged or submerged in

water–Due to impassable roads, trucks may thus not be

able to transport petrol from terminals to gas stations

Disruption to energy supply

Floods: How Can Cities Prepare For Floods?15

During floods, power lines

may be damage

d and power

outages may

occur. These power

failures can last

for weeks before

they are restored.

Due to the lack

of electricity, factories

and companie

s are unable

to operate.

Disruption to

energy supply may

result in loss of employment and

income for

individuals and

companies.

Step 1: Read the text Step 2: State the economic impact. Step 3: Describe the impact by supporting it with evidence from source.(You can underline the evidence in your text) Example: Economic impact: Damage to machinery and

equipment Describe: 1055 new cars Honda will be scrapped

Source – Text/ Article

Layers of meaning Step 1: Describe what you see from the picture and write your answers in the first box.

Step 2: Using your answers from the first box, further infer what might happen before the picture was taken.

Source A

1.State what is the economic impact in source A. (1m) Damage to machinery and equipment

2.Describe the economic impacts of flood by supporting it with evidence from the source A (3m). The flood has caused automobile companies to stop production. This led to a fall in supply of automobiles. Companies suffered substantial loss. People may also lose their jobs.

Picture 1:Trooper Marcus Gonzales walks on the Highway 12 bridge over the Blanco River in Wimberley, Texas on Sunday

Q1: What does the photography definitely tell me? (Describe the photograph)(1m)

Highway 12 has become impassable due to the large trees that have fallen.

Picture 1

Q2: What can I infer from the photograph? State the economic impacts. (4m)

Damage to transport infrastructure – The force of the floodwater was so powerful that it causes large trees to fall onto the highway. Hence causing the highway to be impassable.

Disruption to energy supply – As the highway is impassable, trucks which transport gasoline from terminals to gas stations are unable to do so.

Picture 2: Typhoon Hagupit ripped out power lines.

Q1: What does the photography definitely tell me? (Describe the photograph) (1m)

Power lines are being destroyed.

Picture 2

Q2: What can I infer from the photograph? State the economic impact. (4m)

Disruption to energy supply - During floods, power lines may be damaged and power outages may occur. These power failures can last for weeks before they are restored. Due to the lack of electricity, factories and companies are unable to operate. Disruption to energy supply may result in loss of employment and income for individuals and companies
