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... |

The rapidly growing beef cattle herd of the Peoples Republic of China is largely carried as small numbers of animals on smallholder farms. These enterprises have traditionally focussed on cereal and vegetable crops. Limited plantings of specialised forages combined with a poor knowledge of ruminant nutrition by sm allholder farmers represent a serious challenge to establishing genuinely sustainable beef enterprises for this sector. Government policy to promote beef cattle production on smallholder farms is now focussing on the use of new forages and improved feeding practices. The paper draws on some economic insights from an Australian Centre for International Agricultural Research (ACIAR) project that is exploring options for integrating the planting and... |
