Bevolkingsverspreiding en –digtheid op ‘n wêreldskaal
Module 5
Bevolkingsverspreiding
Die woord bevolkingsverspreiding kan maklik ontleed word.
Bevolking verwys na mense en
verspreiding dui op waar hierdie mense woon - waar mense op die aarde woon. As jy na die meegaande wêreldkaart kyk, sal jy sien dat die mense nie eweredig oor die wêreld versprei is nie. In sekere gebiede is daar groter konsentrasies mense as in ander.
1. Faktore wat die beweging van mense en hul vestiging beïnvloed
Daar is meer as 6 miljard (6 000 miljoen) mense op die aarde en hulle bewoon maar ongeveer 15% van die aarde se oppervlakte (sien sirkelgrafiek).
Daar is sekere faktore wat ‘n groot rol speel in die keuse van ‘n plek van vestiging.
N atuurlike faktore:
Klimaat:
Aangename temperature (tussen 10
o C en 30
o C) en gemaklike lugvogtigheid lok mense. Daar moet nie toestande van uiterstes soos windstorms of uitermate hoë reënval wees wat die gebied teister nie. (Meer oor die klimaat se rol in Module 3.)
Hulpbronne:
Mense gaan waar daar in hul basiese behoeftes voorsien kan word, en voedsel en water is die belangrikste van hierdie behoeftes.
Menslike faktore
Ekonomie:
Waar daar geld te maak is, daar sal mense hulle vestig (dikwels ten spyte van ‘n onaangename klimaat).
Politieke besluite:
‘n Land se regering kan deur sy besluite omstandighede vir sy inwoners baie onaangenaam maak en daardeur verskuiwing van mense teweegbring.
Iets interessants: - Ongeveer 90% van die wêreldbevolking woon in die Noordelike Halfrond.
- Ongeveer 60% van die wêreldbevolking woon in gebiede wat laer as 200 m bo seespieël geleë is.
Aktiwiteit 1:
Om ‘n wêreldkaart as ‘n groep te bestudeer om inligting te verkry
[lu 1.1]
Bestudeer ‘n wêreldkaart in jul atlasse om sodoende as ‘n groep moontlike antwoorde op die volgende vrae te vind:
Om watter rede is die gebiede by a, b en c yl bevolk?
Om watter rede is die bevolking by d en e ook besonder yl?
Het die Amasonerivier in Brasilië iets met die bevolkingsverspreiding in dié land te doen? (Verduidelik)
Gee moontlike oorsake vir die bevolkingskonsentrasie in die noordoostelike hoek van Afrika.
Sou julle sê dat Australië verstedelik is?
2. Die keuse: in die stad of op die platteland?
Die meeste van die graad 6-leerders in Suid-Afrika woon in die stad of op ‘n groot dorp! Hoe weet ons dit? Ons weet dit, want meer as die helfte van ons land is
VERSTEDELIK. Dit beteken dat meer as 50 % van ons land se mense in groot dorpe of stede woon. Sulke syfers word met
sensus opnames vasgestel.
As jy die kaart op bladsy 3 ondersoek, is dit duidelik dat die mensdom nie eweredig verspreid oor die aarde woon nie, maar op sekere plekke gekonsentreer is. Maar dit was nie altyd só nie. Van die vroegste tye af was daar stede, reeds in die Bybelse tye al, maar steeds het die meeste mense nie in daardie stede gewoon nie. Eers sowat 50 jaar gelede kon ons sê dat die meeste mense in ons land nie meer op die platteland woon nie, maar in stede saamgetrek is. En hierdie syfer wissel van land tot land.
In die verskuiwing tussen die stad en die platteland het
tegnologie nog altyd ‘n belangrike rol gespeel. Soos nuwe beroepe ontstaan, so sal mense van werkplek en dikwels van woonplek verander. In die praktyk beteken dit dat mense van die platteland na stede toe sal trek meesal om ‘n nuwe betrekking te aanvaar.
Die aanwending van tegnologie beteken ook dikwels dat die mens met die masjien vervang word en dat die persoon wat sy werk verloor het, hom na die stad wend omdat daar waarskynlik meer werkgeleenthede is.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

Where is quantity of cut flower produced, I is labour input and K is fixed capital input (K-5). Determine the average product of labour (APL) and marginal product of labour (MPL)
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
