Modelling the Wheat Sector in South Africa
نویسنده
چکیده
In this study, the structure of the South African wheat market is analysed using economic theory and econometric modelling techniques. The model is used to make baseline projections regarding the supply and use of wheat in South Africa and to analyse the impacts of various policy alternatives on the wheat sector for the period 2004–2008. Results indicate that the area harvested in the summer as well as winter region will decrease over time. Domestic consumption will marginally increase over time, which will result in higher levels of imports. The ability of the model to simulate policy shocks is illustrated by means of simulating the impact of the elimination of the wheat import tariff on the wheat sector.

Microbial Quality of Ready-to-Eat Street Vended Food Groups Sold in the Johannesburg Metropolis, South Africa
Background: In many developing countries, the risk of contracting a food-borne disease is high after consuming contaminated ready-to-eat Street-Vended Foods (SVFs). The main objective of this research was to assess the microbiological quality of SVF groups sold in the Johannesburg Metropolis, South Africa. Methods: A stratified random sampling procedure was used for collecting the ready-to-eat...
متن کاملInfluence of Operational Parameters and Kinetic Modelling of Catalytic Wet Air Oxidation of Phenol by Al/Zr Pillared Clay Catalyst
Single and mixed oxide Al/Zr-pillared clay (Al/Zr-PILC) catalysts were synthesized and tested for catalytic wet air oxidation (CWAO) of aqueous phenol solution under milder conditions, in a semi-batch reactor. The catalysts were synthesized from natural bentonite clay using ultrasonic treatment during the aging and intercalation steps and were characterized <...
متن کاملParametric model based assessment of genotype×environment interactions for grain yield in durum wheat under irrigation
The objectives of this study were to assess the genotype (G) by environment (E) interaction of grain yield of durum wheat(Triticum durum Desf.) based on parametric models, additive main effects and multiplicative interaction (AMMI) and joint linear regression models; and compare the relative efficiency of the two models in explaining the GE effects. Twenty-three genotypes were evaluated across ...

Historically, the design of the in-stope pillar in underground excavations has been based on empirical formulae and numerical modelling. Although these design methods have been extensively applied in several gold mines in South Africa, rockburst, in-stope pillar burst/failure are continuously reported as the major problem faced by mines. Therefore, this study attempts to compare the performance...
متن کاملEvaluating the efficiency of the wheat tariff regime in South Africa
A drastic change in the marketing system of wheat in South Africa has taken place over the past decade. For the first time an import tariff on wheat was implemented in the form of a variable import levy. Traditionally, countries have implemented variable import levy schemes in order to protect domestic price guarantees by means of determining a reference price, which was generally above the dom...
