A Study of Press Freedom in South Africa

Description: The problem of the study was to analyze conditions of the South African press, including effects of apartheid legislation on the free flow of information. The method of research was mail questionnaire to editors of twenty-two South African daily newspapers. The study showed that the South African press is restricted by legislation and additional laws are expected. Other information from the study includes the following: at least four main laws impede the free flow of information; the press has ready access to government officials; Die Burger and The Star are considered the most influential newspapers; and Prime Minister Vorster's recent advice that the press "put your house in order" seems aimed largely at key English-language newspapers.

Media Agenda-Building Effect: Analysis of American Public Apartheid Activities, Congressional and Presidential Policies on South Africa, 1976-1988

Description: The mass media's role in informing the American public is critical to public support for government policies. The media are said to set the national agenda. This view is based on the assumption of selective coverage they give to news items. Media coverage also influences the salience the public attaches to issues. However, media agenda effect has been challenged by Lang and Lang (1983). These scholars, in their media agenda-building theory, argued that the success of media effect on national agenda is dependent on group support. In order to test this theory, time-related data on South Africa crises, media coverage"of South Africa, American public reactions, congressional, and presidential apartheid-related activities, between 1976 and 1988, were analyzed. Congressional anti-apartheid policies were the dependent and others, the independent variables. The theory made analysis of the data amenable to the additive adopted to test for the significance of the interactive variables, indicated that these variables were negatively related to congressional anti-apartheid policies. The additive model was subsequently analyzed. The time series multiple regression analysis was used in analyzing the relationships. Given autocorrelation and multicollinearity problems associated with time series analysis, the Arima (p, d, q) model was used to model the relationships. This model was used to indicate support, or nonsupport, for the time series regression analysis. The result of the additive model indicated that South African political crises were negatively related to congressional anti-apartheid actions. It also showed that the relationship between the American public reactions and congressional anti-apartheid policies was greater in comparison to all other independent variables. The presidential actions taken against South Africa were negatively related to Congress' anti-apartheid actions. Television had the greatest relationship with congressional anti-apartheid actions compared to newspapers and magazines.

The Kalahari Transect: Research on Global Change and Sustainable Development in Southern Africa

Description: The Kalahari Transect is proposed as one of IGBPs Transects (see Koch et al. 1995 [IGBP Report 36]). It is located so as to span the gradient between the arid subtropics and the moist tropics in southern Africa, a zone potentially susceptible to changes in the global precipitation pattern. Its focus is the relationships between the structure and function of ecosystems and their large-scale biophysical and human drivers (climate, atmosphere and land use). The Kalahari Transect spans a strong climatic gradient in southern Africa, from the arid south to the humid north, while remaining on a single broad soil type, the deep sands of the Kalahari basin. The vegetation ranges over the length of the transect from shrubland through savannas and woodlands to closed evergreen tropical forest, with land uses ranging from migratory wildlife systems, through pastoralism, subsistence cropping to forestry. The objectives of the Kalahari Transect activity are to: build an active network of regional and international researchers around the issue of ecosystem structure and function in savanna woodlands undergoing climatic and land use change; quantify the current and future role of southern African savanna woodlands in the global carbon, water and trace gas budgets and the degree of dependence of these budgets on climate and land use change; develop a predictive understanding of future changes in southern African savannas and woodlands on sandy soils, including their capacity to deliver forage, timber and other products. A five year project is proposed, commencing in 1997. The project revolves around four themes: vegetation structure, composition and dynamics; biogeochemistry, trace gas emissions and productivity; resource use and management and water and energy balance. These themes define the minimum set of processes necessary for understanding of the Kalahari system.
