In the Shadow of the Gold Mines: Migrancy and Mine Housing in South Africa

The profitability of the gold mining industry has long been based upon the exploitation of the vast reserves of African migrant labour drawn from South Africa and the sub-continent. A central institution of the migrant labour force has been and continues to be the vast housing complex, where the majority of the industry's 700 000 migrant workers are housed in single-sex barrack-like accommodation under the tight control of the mining industry. Although in recent years the gold mining industry has attempted to use alternative housing strategies for its married migrant workers, today the barrack-like housing complex remains the most important institution of labour control in South Africa. This paper examines the mine housing complex and the social control mechanisms deeply embedded in the design and social organisation of migrant workers' housing in South Africa. Although the new Government of National Unity is committed to improving the housing circumstances of all South Africans, mine workers face a housing problem inherited from segregation and apartheid which requires particular attention from employers, the government and the unions representing the mine workers.     

The Impact of Mine Downscaling on the Free State Goldfields

Mine downscaling is a common international phenomenon; and the deindustrialisation related to mining that occurred in the global north between 1960 and 1990 has been the focus of numerous studies. Mine downscaling in Africa, and more specifically in South Africa, has only risen to prominence in the last two decades. This paper examines the consequences of mine downscaling in the Free State Goldfields of South Africa, against the background of similar impacts in the international arena. Although many of the experiences recorded in the case study mirror the international experience, it is argued that it is probably unrealistic to expect local attempts alone to address mine downscaling, since the magnitude of such downscaling, as described in the paper, is too vast. Subsequently, the paper argues in favour of local partnerships, but with a national strategy for locations that have been affected by the impact of mine downscaling.     

Biological nutrient removal without the addition of chemicals

Lower per capita water consumption and higher chemical costs result in the unit costs for the conventional removal of plant nutrients in South Africa being considerably higher than those in the United States. In addition, large areas of South Africa are semi-arid and the reuse of water at least for industrial purposes and for recreation has become essential. This led to a search for less expensive methods for the removal of nutrients from domestic wastewater.     

African Urbanism: the Geography of Urban Greenery

Whilst the issue of urban greenery has received considerable research attention in many individual African countries in recent years, little has been done to explore and document the influence and the management implications of urbanisation on urban greenery across Africa. To address this gap, this paper reviews the state of urban greenery across African cities by analysing urbanisation pressures on the preservation and management of urban greenery. Drawing from published literature, policy documents and international reports, the study findings indicate an increasing depletion of urban greenery across major cities in Africa owing to urbanisation-induced anthropogenic influences. This paper advocates for an urban resilience model to management of urban greenery.     

The management of greywater in the non-sewered areas of South Africa

The management of greywater in the non-sewered areas of South Africa has been identified as a key area of research owing to the fact that very little, if any, provision has been made for it. Without water-borne sanitation, the disposal of greywater becomes a problem that has the potential to create a host of environmental and health problems, and this is particularly evident in the high density informal settlements that surround the major South African cities. The main aim of this study was to understand the use and disposal of greywater in the non-sewered areas in South Africa, determine typical quantities and qualities, and develop a preliminary guide for its management, both in terms of reducing health and environmental risks as well as possibly providing benefits through controlled reuse.

Hear no housing, see no housing: Immigration and homelessness in the new South Africa

The housing crisis in South Africa has received an enormous amount of attention from governments, NGOs and academics. One issue that has been virtually ignored, however, is housing for non-citizens – particularly poor, undocumented migrants from other parts of Africa who are arriving in the country in search of work and accommodation. This paper explores official government policy on the issue as well as ground-level attitudes of citizens and non-citizens. Although little has been done to address this potentially explosive issue, there are grounds for optimism for progressive policy development.
