| This paper evaluates the production structure of the South African agricultural sector for the period 1970-1998, using a translog function. The results show that the production structure is best represented by production technology that is Hicks-neutral and homothetic. This information is useful in evaluating the results of previous research on the structure of South African agricultural production, particularly relatively recent research on elasticities of substitution. In addition, it also provides the basis for meaningful future analysis of aspects related to the production structure of agriculture. |

| This study employed a Tobit model to examine factors that influence the adoption and intensity of utilisation of improved maize varieties in the West Shoa Zone in the central highlands of Ethiopia. The estimated results indicate that level of education, household labour, farm size, extension services, farm income, and timely availability of improved maize seeds significantly influence the adoption and intensity of use of improved maize. It also showed that the impact of off-farm income and age of the household head on adoption and intensity of use of improved maize seed was insignificant. |

| This paper assesses the likely impact on the agricultural sector of the Southern African Development Community (SADC) countries of the Harbinson modalities, along with the EU and US proposals as alternative scenarios in the context of the ongoing negotiations of the WTO Agreement on Agriculture. Impacts are assessed on a number of indicators, notably government revenue, producer, consumer and total welfare measures and trade flow. Reflecting country- and commodity-specific factors, the three modalities have different impacts on the indicators. The SADC as a whole is found to lose in terms of total welfare under all three proposals. But while this loss under the Harbinson and EU proposals is due to declines in consumer surpluses and government revenues,... |

| This study employed a Ricardian model that captures farmers' adaptation to analyze the impact of climate change on South African Sugarcane production under irrigation and dryland conditions. The study utilized time series data for the period 1977 to 1998 pooled over 11 districts. Results showed that climate change has significant nonlinear impacts on net revenue per hectare of sugarcane in South Africa with higher sensitivity to future increases in temperature than precipitation. Irrigation did not prove to provide an effective option for mitigating climate change damages on sugarcane production in South Africa. The study suggests that adaptation strategies should focus special attention on technologies and management regimes that will enhance sugarcane... |

| In this paper a simple growth model is adapted to explain the effect of the agricultural sectors' growth on the non-agricultural sector. The empirical results suggest that for a 1% growth in the agricultural sector, the non-agricultural sector responds by more than 1%. The results also confirm that productivity difference exists, the non-agricultural sector being more efficient in terms of input use. The empirical results support the argument of President T. Mbeki, that South Africa should follow an "agricultural-led" growth strategy for successful development. |

| In this study, an econometric model of the South African maize and sorghum sector is estimated. Using the developed model, a market outlook for the two major grain sectors – maize and sorghum - for 1999/00 to 2006/07, is generated under the specified assumptions. Results indicate that for both maize and sorghum, consumption will gradually increase over time. In spite of varying areas of maize and sorghum being harvested, total production will also gradually increase over time due to increases in particularly yields. |

| Merino rams are an important input in the Merino breeder's production process. Breeders need to make informed decisions when buying rams because of the influence that the ram will have on the characteristics of the herd, especially with regards to the characteristics of the animal that are deemed economically important. Before the advent of performance testing through objective measurement a system of subjective evaluation was used to determine the breeding value of Merino rams. The use of the subjective system of evaluation seemingly continues and the prevalence of this system of evaluation raises the question to what extent ram buyers are using performance measurement indices in aiding them in their buying decision. This study finds that performance... |
