background. Label the three sections at the side of the photograph.
(b) Describe the landuse in the foreground and the background.
• Foreground — Vegetable farming
• Background — Housing
(c) Explain why the landuse in the background is more commonly seen in Hong Kong

2. (d) What is the opportunity cost of giving up the landuse in the foreground for the
landuse in the background?
There will be less land for vegetable farming and this may affect the supply of vegetables.
(Accept other plausible answers.)
2. Complete the mind map below and answer the questions that follow.
What are the responses to the
rising demand for land?
Increasing price of land Increasing supply of land Conserving land
Land clearance Land reclamation Maximising use of
existing land
(a) Explain briefly how the rising demand for land can lead to an increase in the price of
land.
In a country or a city where the land area available for use is limited and the demand
for land is high, there will be increased competition among users for the available
land. Some users may be willing to pay a higher price for the available land and this
will push up the price of the land.
(b) Land clearance is one of the ways to increase the supply of land. Describe one way in
which land clearance can affect the environment negatively.
Land clearance by deforestation will have a negative impact on the environment.
When forests are cleared, the habitats of many plants and animals are destroyed. This
can affect the entire food chain and lead to the extinction of some plant and animal
species.
(Accept other plausible answers.)
