Nature conservation areas and environment

The United Nations Organisation’s ideal is that countries should manage 10% of their territory as nature conservation areas. In South African terms this would include National Parks (like the Kruger National Park), reserves that are managed by the Departments of Nature Conservation of the different provinces, reserves that are under municipal control, as well as land owned privately, e.g. by mining companies and other organisations and farmers who manage a section of their land as reserves, game parks and game farms.

South Africa is not doing too well in this field, because only 7% of the country was managed as nature conservation areas in 2000. This situation may be improving as more land is continually being added to land that has already been set aside for conservation.

Land use in the Western Cape

Activity 1:

To identify important nature conservation areas in south africa

[lo 2.1]

Complete the table:

The name of the National Park closest to your own town or city. A description of the nearest provincial nature conservation area.
Does your municipality manage a proclaimed nature conservation area? Describe it. Provide the name of a private nature conservation area near you.

Nature conservation areas do not necessarily have to focus on the protection of plants or animals. Mountain catchment areas are frequently managed to protect vegetation so that rainwater will soak into the soil to supplement the underground water supply instead of flowing into the sea.

It should be clear why the nature conservation areas of any country would be the parts of the country with the lowest population density.

What about the people and the environment?

Mining and industry have many advantages for the country, but thorough consideration should be given to their effect on people and the environment.

In large mining and industrial areas, dust and gases are released into the air, and this has an effect on the people who work at the mines and in the industrial areas, and on the environment!

Activity 2:

To find out how people and their environment influence one another

[lo 2.3]

  • Make a list of the possible dangers to people and the problems for the environment in an area such as South West Mpumalanga with all its coal and platinum mines:

Dangers that threaten people:

Dangers that threaten the environment:


LO 2


The learner will be able to demonstrate geographical and environmental knowledge and understanding.

We know this when the learner:

2.1 identifies and describes major physical features of South Africa, including those of the home province [people and places];

2.2 identifies links between natural resources and economic activities in South Africa [people and resources];

2.3 describes ways in which the physical environment influences human activity and how human activity is influenced by the physical environment [people and the environment



  • Dangers: - Poor health - Lower standard of life and life expectancy
  • Problems: - Gases (air-pollution) - Polluted water - Soil absorbs toxic waste - Has an effect on quality of agricultural products

what does nano mean?
Anassong Reply
nano basically means 10^(-9). nanometer is a unit to measure length.
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
