Xenophobia and attacks on foreigners in South Africa have been in news lately and made international headlines. In April 2015, there was an upsurge in xenophobic attacks throughout the country. The attacks started in Durban and spread to Johannesburg. Zulu King Goodwill Zwelithini has been accused of fuelling the attacks by saying that foreigners should "go back to their countries". However, BBC News reported on 19 April 2015 that he said his comments were distorted. Nevertheless, locals looted foreigners' shops and attacked immigrants in general, forcing hundreds to relocate to police stations across the country. The Malawian authorities subsequently began repatriating their nationals, and a number of other foreign governments also announced that they would evacuate their citizens (Los Angeles Times, 17 April 2015). On 23 April several thousand demonstrators marched through central Johannesburg to protest against a spate of deadly attacks on immigrants. They sang songs denouncing xenophobia and carried banners that read "We are all Africans" as migrant workers crowded balconies, shouting their support (http://en.wikipedia.org/wiki/Xenophobia_in_South_Africa#cite_note-Hundreds-71

The attacks on foreigners were focused in specific locations in Durban and Johannesburg. However, foreign people are settled throughout South Africa but there are clear patterns in distribution that reflects on the very basic fabric of South African society. In this blog we will show how foreigners of African origin are spatially distributed throughout South Africa. The data was obtained from the 2011 national census’ figures on migration.

Before venturing in the spatial distribution of foreigners, the question is how many foreigners are there in South Africa. Various sources makes various estimates. However, the 2011 Census shows the flowing figures:

SADC (Southern African Development Community) is a regional organisation consisting of 14 member countries (Angola, Botswana, Congo (DR), Lesotho, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania, Zambia and Zimbabwe). Being South Africa’s immediate neighbours they contribute 90.3% of the migrant population originating in Africa. The rest (9.7%) comes from the rest of Africa. Note that the numbers do not reflect on the legal status of these migrants.

It is clear that Gauteng accommodates more immigrants that the rest of the Country together. The Northern Cape has the least (0.8%) with the Eastern Cape and Free Sate with 3.0% and 3.3% respectively. The rest of the province all have less than 10%. Immigrants from the rest of Africa predominantly settled in Gauteng and the Western Cape.


Utilising Johannesburg as a case study, the map reveals a pattern that is persistent throughout the major urban areas of South Africa. The maps shows the following:
  • Migrants from SADC countries tend to concentrate on the urban edge and particularly on small holdings and farms.
  • There are concentrations in the CBD of the city and it satellite towns such Germiston and Benoni.
  • There is a clear correlation between migrants and settlement in industrial areas.
  • Higher income areas (northern suburbs) attract proportionally more migrants from SADC countries than the traditional black townships.

Turning to migrants from the rest of Africa (excluding the SADC countries) a different pattern emerges.

The following is apparent:
  • There is again a strong propensity to settle close or in the CBD and specifically high density areas and in the older parts of the city close to the CBD. 
  • Settlement is clearly associated with higher income areas with nearly a total absence of settlement by these migrants in previously black townships.
The next series of maps shows the position in Tshwane, eThekwini and Cape Town. There is practically no exception to the identified patterns.





In conclusion it is worth looking at total migration from a broader perspective that shows what is happening in the rural areas.

The following should be noted:
  • There is s propensity to settle in areas close to the border in the northern parts of the country. There are substantial concentrations in the Groblersbrug area (South Africa/Botswana on the N17), Pontdrift (South Africa/Botswana) and Beitbridge (South Africa/Zimbabwe) and between South Africa and Mozambique through the Komatipoort border post. The patterns are less prevalent between South Africa and Lesotho (Quaggasnek might be an exception) and Swaziland and Namibia.
  • There is a close association between high intensity agricultural areas and migrants from SADC countries. This shows in the Musina area, the Louis Trichardt - Levubu area, the irrigation areas around Modjadjiskloof and in the Loskop Dam irrigation areas. The same pattern is also evident in the area cultivating sugarcane around Malelane and Komatipoort in Mpumalanga.
  • There also seems to be propensity to settle close to mining areas. This applies to the Steelpoort area and around Mokopane and Rustenburg. This pattern is also clear around Sishen and Kuruman and the Free State Goldfields.
  • It is clear that very few migrants settle in tribal areas. This might be because tribal chiefs control settlement or the marginal economic opportunities in those areas. This pattern is very strong and there are very little on no migrants in these areas.

These maps only show the spatial patterns that do exist and does not purports to be any in depth analysis of migration and settlement. Further work on migration can be done by considering settlement types such as formal and informal settlements, income patterns and distribution. We also suspect there might be link between the extent of migrant settlement and voting patterns in the previous elections.

General plans and urban growth in South Africa

Work done by town and regional planning consultants is broadly divided between the so-called “strategic” work on the one hand and the “land use management” or “land use control” work on the other hand. Very often it culminates specialisation for town and regional planners either one of these fields. Generally the “strategic planners” deals with long-term outcomes of planning and development and the land use planner with town planning schemes, cadastre and title deeds. The strategic planning not paying much attention to cadastre.

But first on cadstre in South Africa (https://www.fig.net/cadastraltemplate/countrydata/za.htm). The first land surveyors came to the Cape in approximately 1658, five years after Jan van Riebeek had established the first European settlement at the Cape. The first cadastral survey was for a piece of land along the banks of the Liesbeek River in order to transfer land to a released servant of the Dutch East India Company. Until 1857, surveys were represented in a graphical manner using natural features as boundaries. After 1857, theodolites were used and the recording of numerical data on diagrams was compulsory. The British occupation introduced legislation (Cradock Proclamation) in 1813 that no sale of land would be recognized unless the land had been properly surveyed and registered. In 1971 the Sectional Title Act made it possible for the first time in South Africa for flats (apartments) and other portions of buildings to be individually owned.

South Africa is fully covered by the National Control Survey System (NCSS) which is of high accuracy and which is marked by a network of Trigonometrical stations and Town Survey Marks. It is a legal requirement that all cadastral surveys be connected to this system. As from 01-01-1999 the NCSS has been based on the World Geographic System 1984 ellipsoid with the position of the Hartebeesthoek Radio Astronomy Telescope as the origin of the system.

The primary function of the Cadastral System in South Africa is to define (delineate and document) ownership rights. Any land that has not been transferred from the state to a juristic person remains the property of the state. Any juristic person that has been granted freehold rights is free to trade (transfer at market value) that immovable property. Accurate delineation of the ownership rights has enabled the development of a Cadastral Information System, which forms the basis for land valuation; land taxation, development planning, local authority demarcation and land administration.
There is a Surveyor-General in Pretoria, Cape Town, Bloemfontein and Pietermaritzburg. The 9 Provinces have been divided between the 4 Surveyor-Generals. Each Surveyor-General is more or less autonomous within his or her area of jurisdiction. The principal functions of each Surveyor-General is to:
  •  Examine and approve diagrams, general plans and sectional title plans that are lodged for approval prior to them being registered in a Deeds Registry.
  •  Preserve and keep up to date all approved documents and records pertaining to cadastral surveys.
  • Supply copies of documents kept in the office in hard copy or digital form.
  • Provide advice and information pertaining to the cadastre.

      There are diagrams used for registration purposes and sectional plans showing the relative position of two or more units within a sectional title scheme but it is the general plan that interests us.
A general plan is a document consisting of one or more sheets showing the relative position of two or more pieces of land. It is compulsory to prepare a general plan for any subdivision of land into ten or more pieces or when required in terms of any law, such as township establishment or the amendment of an existing general plan. General plans may comprise many sheets and depict a very large number of erven.
In the normal run of play, town planners in the strategic branch of planning will not pay much attention to general plans. However, since the subdivision of land has been meticulously recorded it does not only describe land parcels but shows the history of growth and development over a time period of more than two centuries.

The interest in general plans lies in the emerging structure of settlement they describe. The map below shows how Tshwane developed from the 19th century to date through mapping the age of general plans.



The growth from the original core follows a very concentric pattern. This is despite the strong physical barriers such as the Magaliesberg and the two another parallel ranges present immediately north and south of central Pretoria. The only exception to concentric growth is immediately to the south where the Fountain Valley, Groenkloof Nature Reserve (the oldest proclaimed nature reserve in South Africa - 1895) and the military bases of Thabatswane are located. Secondly, general plans (subdivisions) had become smaller over time and more so in the last few decades. This might be due to the cost and risks over very large development and also due to development moving into the zone of agricultural holding that was established around cities in the earlier parts of the twentieth century. Thirdly, notwithstanding government policy and development theorists being very vocal about densification and urban growth edges, development has happily continued to spread outward.

By browsing the map, one can also see how extensively farms were surveyed in the old Cape Province. This all happened in the 19th century. Furthermore it is noticeable how many general plans was registered since 1990 but most of them on the periphery of cities and towns. Also, since 1990 there was a proliferation of development in tribal areas but very few of them linking with any major existing development or in anyway contributing to rationalising South Africa’s spatial settlement structure. How ineffective or how little this process in tribal areas contributed to structuring settlement and development will be dealt with in a subsequent blog.


It is clear that there are much to be derived for the urban planner and policy analyst from how the cadastre develops over time. It is not only a reflection of development history but also shows how policy intervention pans out and how it squares up against the forces of development.

So this is MapAble?

We are very excited to introduce you to MapAbleTM. After more than a year’s intensive preparation, brainstorming, code writing, legal advice, nights on the internet, we are ready to launch an exciting addition to the range of mapping facilities available on the internet. However, the history is much longer. MapAbleTM is based on the more than 70 years practical planning, GIS and application development of its partners. The forerunner technology from which we develop MapAbleTM exists for many years already and is applied by a number of institutions in South Africa. We have used our experience to re-engineer and repackage our product into flagship technology which is now at the disposal of anyone interesting in maps, spatial analysis and planning.

MapAbleTM is so much more than a web based mapping facility. We have launched MapAble to bring you affordable high-end, cutting edge, cloud based mapping and geographic information system (GIS) technology. The key is that we bring this technology to users that are not GIS experts but who use maps and do spatial analysis as an integral part of their core business activities. Simply, we want to take GIS out of the backroom, demystify it and present it as a day to day tool without which the spatial planner or analyst cannot work.

Our experience has shown that many organisations want a GIS. The route is normally buying very expensive hardware (many millions of Rand) with the surprise that you need to pay licence fees for the software and once ready you still need a “GIS expert” to run the system. Low and behold, if everything is now in place the next surprise is that you need good and relevant data to run your GIS. Should you overcome this, the next challenge is the fact that your GIS expert is a GIS expert and not a subject specialist, so he or she can only act as an interface between you and the GIS. Eventually you end up using a multi-million Rand system to generate very basic maps. It is the same situation we had many years ago before word processing where your draft a document in longhand and then send it to the typing pool to get typed. The question is why we persist with such a situation when we deal with GIS. Imagine having to deal with a spreadsheet department who does you analysis on your behalf? You brief them and they go away and present you with the results after a few days based on your duly completed work order and signed off by the boss. It just doesn’t make sense, so why treat spatial analysis differently as the way we use our normal desktop suite of software. We would like to change this. Our aims are:
  • To be the go to solution for mapping and spatial analysis and planning.
  • To bring mapping and spatial analysis solutions to users that are not GIS experts.
  • To improve the general accessibility to mapping and spatial analysis capabilities and data.
  • To enhance the quality of spatial planning and analysis.
  • To enhance transparency in decision-making based on factual analysis.
The technical capabilities are usually the objectives of existing web based mapping applications. We go two steps further. Our technology is backed by access to data available in the public domain. This enriches the usability of our technology. Yet another step further than the normal presentation of web based technology - notwithstanding the fact that our business is state-of-the-art, our products are backed by a system that provides a human interface to back up our services and enhance the experience of our users.
