Résumé :

A sample of 41 vernacular houses from the Verloenvlei and Lange Vlei valleys in the Sandveld on the Cape West coast, have been subjected to a structuralist analysis of their form. As elements of human material culture these houses represent the physical objectification of invisible culture. They are the products of a culturally dictated mental process of design, and in their form reflect the successful mediation by their creators of a set of binary oppositions common to all human experience. The mental rules that guide this process of design, and therefore account for the physical form of the

Résumé :

Summary in English.<br>Bibliography: leaves 263-292.<br>This thesis presents new palaeoenvironmental evidence from the semi-arid lowlands of the West Coast Sandveld, which prompts a fresh synthesis as to the nature of late Quaternary environmental changes in the southwestern Cape's fynbos biome. The study is centred on Verlorenvlei, a remote coastal lake and swamp system which is ideally situated to investigate the complex interactions between late Holocene climate change, vegetation change, sea-level fluctuation, lacustrine/estuarine/fluvial sedimentology and human activity in the Sandveld re

Thesis (MSc)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: A land cover classification showing the landscape structure of a given area is necessary to make appropriate measures for environmental planning. The environmental impacts from insensitive human activities have led to a severe loss of biodiversity in the Cape Floristic Region over time. The natural biodiversity of the North-West Sandveld in particular, has suffered severe loss and a high level of fragmentation. The rapid growth of certain agricultural practices in the Sandveld has led not only to loss of biodiversity, but the se

Résumé :

<p>This research assessed landuse changes and trends in vegetation cover in the Sandveld, using remote sensing images. Landsat TM satellite images of 1990, 2004 and 2007 were classified using the maximum likelihood classifier into seven landuse classes, namely water, agriculture, fire patches, natural vegetation, wetlands, disturbed veld, and open sands. Change detection using remote sensing algorithms and landscape metrics was performed on these multi-temporal landuse maps using the Land Change Modeller and Patch Analyst respectively. Markov stochastic modelling techniques were used to predic

Thesis (MScAgric)--University of Stellenbosch, 2000<br>ENGLISH ABSTRACT: Approximately 7000 ha of potatoes are cultivated under irrigation. The greatest part of the planting is entered under the South African Certification Scheme as seed potatoes, representing between 35 and 40 % of seed production in South Africa. The production of high-quality tubers is, therefore, in the interest of the entire country. Some production factors in the area, however, have a very negative influence on quality with a resultant increase in input costs. These factors include mainly low clay content of the so

Résumé :

Much of the work undertaken in the field of Vernacular Architecture on the West Coast of South Africa has focused on the Verlorenvlei settlement. The buildings of this small settlement have come to define the Vernacular Architecture of the Sandveld. The Sandveld, however, is a relatively poorly understood region in terms of historical research, particularly in the 19th century, but forms an important link between events in the Cape and events on the Northern Frontier in the late 18th and 19th Century. The purpose of this study is to explore, modify and expand the characteristics of Sandveld Ve

Résumé :

The first recorded outbreak of nephrotoxicosis induced by the shrub Nolletia gariepina is reported. The outbreaks occurred in cattle in the Kalahari sandveld of South Africa. The toxicosis was experimentally reproduced, initially in a steer, as a pilot trial to confirm toxicity of the plant material, and thereafter in two other cattle. Toxicity was induced by intraruminal administration of 3 g/kg dried, milled plant material as a single dose. The animals had to be starved for 24 hours before dosing, as dosing on a full rumen did not induce any signs of toxicity during five days of observation

Thesis (MSc)--University of Stellenbosch, 2004<br>ENGLISH ABSTRACT: The Sandveld, a potato growing area of the Western Cape is subject to significant groundwater abstraction for both municipal and agriculture purposes. The climate is arid and sensitive and important ecosystems in the area are showing varying degrees of impact. Management measures are needed to ensure ongoing sustainable development of the area.

This area falls within the winter rainfall (or Mediterranean) region of South Africa and has a sharply defined seasonal climate. Vegetation in the region is unique. The soils in the Swartland and Sandveld vary greatly over short distances, making this area vulnerable to varying erosion rates. Land use in the Swartland and Sandveld is mainly agricultural.

It is well documented as an area under threat of severe natural resource depletion if it is not well managed with sustainability in mind.

M.A.<br>Natural phenomenon such as droughts have a definite influence on the availability of water sources, soil profiles and vegetation of an area. Man should adapt his activities, such as farming, to the current climatic elements of the area to ensure his existence. Intermittent rainfall and the occurrence of droughts caused symptoms such as desertification. Desertification has reached an alarming level in South Africa, so much so that the level of environmental degradation in the Northern Cape Province caused great distress. This caused many questions into the activities of man in this area
