Geography: settlements

Module 1

Land use patterns

The origin and functions of settlements differ. We shall take a brief look at the different types of land use in a town or city in South Africa.

South Africa has some densely populated urban areas. These include areas such as Gauteng and the Cape Town City Metropole. The Nelson Mandela Metropole which includes Port Elizabeth, Uitenhage and Despatch, is another densely populated area. On the other hand there are certain parts of the country where the population is very sparse. Do you know of any such areas? ……….. The Northern Cape Province perhaps? In some of these country towns the population is in fact decreasing. This is partly due to the depopulation of the rural areas, resulting from the pulling and pushing factors that you have already studied.

In a small town like Hofmeyr in the Eastern Cape, there are only about five hundred inhabitants. Many businesses in this town have already closed down. There is not enough spending power left to make businesses profitable. Even banks have already closed their doors. This also influences the prices of houses. Prices have dropped considerably over the last few years. Many home-owners cannot find buyers for their homes. They practically have to give their homes away.

Activity

To interpret information from sources and answer questions that arise from this knowledge

[lo 2.1]

1. Why do you think certain urban areas are expanding, while others (especially in rural areas) stagnate?

2. Define the term “depopulisation.”

3. What kind of problems do property owners in rural areas experience where the population of small towns is dwindling?

4. Do you think there is a relationship between the depopulation of the rural areas and the pressure on urban areas to supply housing and an infrastructure?

1. Different land use zones in the city

If you study a map of any town or city, it becomes clear that not all the land is used for the same purposes. There are various functions to be fulfilled in any particular town or city, and these take place in different areas. Industries, for example, are usually found on the outskirts of a city, while the head offices of large organisations are likely to be in the central business district.

As any city has different needs, there are different kinds of businesses, institutions or persons to supply in these needs. Just think of sport for a moment. Which amenities in your area cater for sport? Cities also have many other functions. Let’s have a look at some typical land use zones in the city:

1.1 C entral Business District (CBD)

The Central Business District is the heart of any city and its function is commercial. All cities have such an area. The location of the CBD usually offers easy access to all the main traffic routes. The price of land in the Central Business District is usually exceptionally high, so that most buildings in this area are very tall. In the course of time, as the city expands, the CBD of any given city may move to a new location. In Port Elizabeth for example, the CBD was once close to the harbour. The area has since moved to Cape Road, which is further away from die original CBD.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul
hmm
Abhi
is it a question of log
Abhi
🤔.

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials

this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
Ali Reply
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
