Industrial decentralisation in South Africa: tool of Apartheid or spontaneous restructuring?

Industrial decentralisation (ID) has been a central component of South Africa's regional strategy for over twenty years. Until recently, though, the programme has evinced little interest amongst industrialists. The fact that ID policy has been premised upon political rather than economic considerations has been thought to lie at the root of this failure. Following recent developments, however, this view is being reassessed. The reorganisation of ID policy in 1982 and the dramatic acceleration in the rate of industrial relocations that this reorganisation appears to have induced, has led theorists to revise their thinking on both the economic and political imperatives underpinning the programme. The purpose of this paper is to review the debates that are now developing concerning ID in South Africa, and to suggest where further research and analysis might be most profitably directed.     

Transport and economic development in the less-developed countries: Some reflections on the seaports of Kenya and Tanzania

The significant role of transport in the development of less-developed countries is widely accepted, but the critical importance of seaports is often under-appreciated. Evidence from the Indian Ocean ports of Kenya and Tanzania is used in this paper to illustrate and support the argument that efficient port operation is an essential contributory factor in the development process.     

A volcanic-carbonate association in the Góry Kaczawskie,Western Sudetes

Amidst metavolcanic rocks and phyllites of the Góry Kaczawskie region occur isolated carbonate bodies known as the Wojcieszów limestones. The bodies enclosed in the metavolcanites show primary (sedimentary) contacts, while those in the phyllites do not have such contacts. The Wojcieszów limestones and metavolcanic rocks form sequences displaying mutual spatial and genetical relations. Submarine volcanic elevations were covered with chemical and biochemical carbonate precipitation, the intensity of which was stimulated and controlled by the volcanic activity.

Zusammenfassung Inmitten der metavulkanischen Gesteine und Phyllite von Góry Kaczawskie erscheinen isolierte Karbonatgesteinskörper, die als Wojcieszów-Kalke bekannt sind. Die Karbonatgesteine innerhalb der Metavulkanite zeigen sedimentäre Kontakte, während die in den Phylliten eher tektonisch begrenzt sind. So kann man den Wojcieszów-Kalken und den Metavulkaniten eine räumliche und genetische Beziehung zusprechen. Submarine Erhebungen aus Vulkangesteinen waren mit chemischen und biochemisch gefällten Karbonatserien bedeckt, wobei die vulkanische Aktivität die Karbonatbildung unmittelbar beeinflu\te.

Résumé Parmi les métavolcanites et les phyllites de la région du Góry Kaczawskie, il existe des corps carbonatés isolés connus sous le nom de »calcaires de Wojcieszów«. Ceux qui sont inclus dans les métavolcanites présentent des contacts sédimentaires, contrairement à ceux qui sont inclus dans les phyllites, dont les contacts sont tectoniques. Entre les calcaires de Wojcieszów et les roches métavolcaniques, il est donc possible d'établir des relations spatiales et génétiques. Des reliefs volcaniques sous-marins ont été le siège d'une précipitation carbonatée chimique et biochimique dont l'intensité dépendait de l'activité volcanique.
