Purposes for land use

The lay-out of a town or city plan shows that different areas are allocated for differerent purposes. The lay-out of any town or city must be well-planned. It would for instance be disastrous to allow an industry releasing toxic substances in a residential area. For this reason townplanners work years ahead to regulate each area regarding its functions, transport and land usage. It may however happen that the function of certain buildings change.

In Port Elizabeth for instance, many houses are now used for business purposes. The central business district has since been relocated. Close to Greenacres we are already beginning to see the head offices of banks and insurance companies. What once used to be part of the Mill Park residential area, is gradually becoming business premises.

1. Functions of land usage in South African cities

When we consider land use in an urban area, we find that certain basic functions are usually found in all cities. The total urban area usually consists of a number of developed areas, while others are still undeveloped.

The developed area usually consists of two types of areas, on for private and the other for public development.

Areas for private development

The area for private development usually includes three types of land use functions:

a) Residential – e.g. private homes, terraced houses, flats and townhouse complexes.

b) Industries – e.g. storage, light industries and heavy industries.

c) Commerce – e.g. retail, wholesale, financial and professional enterprises.

Areas for public development

The areas for public development serve four types of land functions:

a) streets

b) recreation – such as parks, sports grounds and culture

c) public services – such as hospitals, airports, cemeteries and sewerage

d) education – primary and high school

Undeveloped areas

The undeveloped areas can usually be classified under two headings:

a) unused, open areas

b) agricultural land

Activity 1:

To describe the role and function of land use

[lo 2.2]

Study this illustration of an urban area and answer the questions:

1. Where is the business district of the urban area situated?

2. Would you describe b as a high-income or a lower-income residential area? Give a reason for your answer.

3. What natural obstruction could prevent possible future expansion of the city in a northerly direction (see c )?

4. Are there adequate sporting facilities to provide in the needs of the city-dwellers?

Activity 2:

To discuss the function of land in any given environment

[lo 2.2]

nb: Teachers should note that this activity is a practical assignment that can be executed in groups of two.

2 The function of the land in my environment

Study the table and additional information and follow the teacher’s instructions to determine the use of land in your own environment.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
