Q

A dispersed (isolated) farming pattern usually develops where:

A

There are many water sources, so farms can spread out

Land is flat and can accommodate a large farm

Land is mountainous but there are scattered patches of flat land - a farm is found on each piece of flat land

Land is infertile - a large farm is needed in order to ensure a large yield

Safety is not an issue - people are able to live on large farms far away from one another

It is the tradition of the people - the Nguni people in South Africa live in dispersed family groups

The type of farming consists of large commercial farms (extensive farming)

Land is privately owned - private land ownership encourages dispersed settlement

Q

What conditions usually cause for a nucleated farming pattern?

A

Water is scarce and people settle around an available water source (wet point site)

Land is marshy and people settle away from water (dry point site)

Land is flat and there may be many farms on a flat piece of land

Land is mountainous and people cluseter together on small farms where there is available flat land

Land is fertile and can suppport many farms

Safety is an issue - people will cluster together in areas where there is conflict

It is the tradition - a Tswana village usually consists of thousands of huts and kraals, usually around a water source

The type of farming is characterised by small subsistence farms, as these farms often cluster together.

Small intensive farms (e.g. horticulture) may also be nucleated as inputs are very costly and farmers can only afford a small piece of land (which is usually close to an urban area)

There is communal land ownership - people live together on the land if it is commually owned

Q

What are some disadvantages of a nucleated (clustered) settlement pattern?

A

All the farmers have to agree on farming methods

Properties are often fragmented or too small to use mechanisation

If soil erosion sets in, everyone is affected as dongas will extend across the farm boundaries

There is less scope for initiative individual farmers

A

Planned villages within the homelands in which to settle black people.

With the introduction of the pass laws (or influx control) people were not encouraged to move to the cities.

Supposedly, the advantage of betterment villages was to make the building of schools and clinics easier - but the people were crowded and far from an urban area that could provide jobs. Also, there was not enough fertile land.
