Ano: 2002 URL: http://purl.umn.edu/18054 Agricultural technology, productivity and employment: Policies for poverty reduction AgEcon Thirtle, Colin G.; Piesse, Jenifer; Gouse, Marnus. This paper begins by arguing that agricultural economics has an important contribution to make to the economic transition of the new democratic South Africa. Policies are required to reduce unemployment, poverty and inequality, but does the work of agricultural economists provide the policy makers with the information necessary to make the correct choices? In this context, we update our recent work on technology, efficiency and productivity in South African agriculture, for both the commercial and smallholder sub-sectors. For the commercial sector, this means extending the total factor productivity index and estimates of the demand for labour. For the smallholder sector, there are new results on the impacts of GM cotton and white maize on output and...

Ano: 2005 URL: http://purl.umn.edu/31719 Can Bt Maize Reduce Exposure to the Mycotoxin Fumonisin in South Africa? AgEcon Pray, Carl E.; Rheeder, John; Gouse, Marnus; Volkwyn, Yvette; van der Westhuizen, Liana; Shephard, Gordon. The mycotoxin fumonisin is associated with oesophageal cancer and birth defects. The Eastern Cape province of South Africa has high levels of fumonisin in maize and oesophageal cancer. This study measures the amounts of the mycotoxin fumonisin in the grain of Bt maize, commercial hybrids, and farmer-saved, local mixtures of seed that were produced and stored by small holders in South Africa. We find that adoption of Bt maize can reduce poor rural consumers exposure to fumonisin. Greater consumption of maize meal milled in modern mills could have a similar impact.

Ano: 2002 URL: http://purl.umn.edu/18022 Monsanto's Adventures in Zulu Land: Output and Labour Effects of GM Maize and Minimum Tillage AgEcon Gouse, Marnus; Piesse, Jenifer; Thirtle, Colin G.. The only commercial genetically modified (GM) subsistence food crop is white maize in South Africa, which was released in 2001/2. This paper reports on the performance of insect resistant (Bt) white maize grown by smallholders in Hlabisa, KwaZulu Natal, where the other development is minimum tillage. The results show that, contrary to many inflated claims, in the dry 2003/4 season, there was no significant difference between the yield per kg of seed for Bt and conventional maize, due to very low stalk borer infestation levels. Farmers who planted Bt maize in 2003/2004 were thus worse off as they paid more for seed and obtained no benefit. This is measured using efficiency scores from a stochastic frontier analysis. These results conflict with the yield per...

Ano: 2006 URL: http://purl.umn.edu/25309 Producer support estimate (PSE) for South African agriculture for 1996, 1997, 1998 AgEcon Kirsten, Johann F.; Tregurtha, N.; Gouse, Marnus; Tswai, J.. This paper endeavours to update the series of PSE calculations based on the 1998 OECD methodology (OECD 1998) which is a slightly revised methodology from the earlier calculations. The OECD terminology also now means that PSE stands for Producer Support Estimate and is calculated by classifying policy measures under a slightly different set of categories.
