Determinants of adoption and intensity of use of improved maize varieties in the Central Highlands of Ethiopia: A Tobit analysis AgEcon
Alene, Arega D.; Poonyth, Daneswar; Hassan, Rashid M..
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.

Forecasting the market outlook for the South African maize and sorghum sector using econometric modeling AgEcon
Poonyth, Daneswar; van Zyl, Johan; Meyer, Ferdinand H..
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.

Representing the production structure of South African agriculture AgEcon
Poonyth, Daneswar; van Zyl, Johan.
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.

MODELLING THE MARKET OUTLOOK AND POLICY ALTERNATIVES FOR THE WHEAT SECTOR IN SOUTH AFRICA AgEcon
Meyer, Ferdinand H.; Kirsten, Johann F.; Poonyth, Daneswar.
In this study, the structure of the South African wheat market is analysed using economic theory and econometric modelling techniques. The developed 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 2002 – 2008. Results indicate that after an initial decline in the area harvested in 2003, the area harvested will increase over time. Domestic consumption will gradually decrease over time, which will result in lower levels of imports and higher level of exports. Three policy scenarios are analysed, the elimination of the import tariff for wheat, a twelve percent depreciation in the exchange rate, and the convergence of...

PERFORMANCE MEASUREMENT INDICES ON THE BUYING BEHAVIOUR OF RAM BUYERS IN THE HIGHVELD MERINO CLUB AgEcon
Jordaan, Daniel du Plessis Scheepers; Doyer, Ockert T.; Poonyth, Daneswar.
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...

Measuring the impact of climate change on South African agriculture: The case of sugar-cane growing regions AgEcon
Deressa, T.; Hassan, Rashid M.; Poonyth, Daneswar.
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...

IS AGRICULTURAL SECTOR GROWTH A PRECONDITION FOR ECONOMIC GROWTH? THE CASE OF SOUTH AFRICA AgEcon
Poonyth, Daneswar; Hassan, Rashid M.; Kirsten, Johann F.; Calcaterra, M..
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.

The impact of the WTO agricultural negotiating modalities on Southern African Development Community countries AgEcon
Poonyth, Daneswar; Sharma, Ramesh; Konandreas, Panos A..
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,...

The impact of real exchange rate changes on South African agricultural exports: An error correction model approach AgEcon
Poonyth, Daneswar; van Zyl, Johan.
This study evaluates the long run and short run effects of real exchange rate changes on South African agricultural exports using an Error Correction Model (ECM). The results suggest that there is a unidirectional causal flow from exchange rate to agricultural exports. Moreover, appreciation of the Rand will be detrimental to agricultural exports.
