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... |

This study aimed at examining the merit of crop diversification as a strategy for agricultural growth in Bangladesh. Specifically, the existence of economies of diversification, scale economies and diversification efficiencies at the farm level were examined using a stochastic input-distance function approach. Results reveal strong evidence of diversification economies amongst most crop enterprises except the combination of modern rice and modern wheat enterprises. Ray economies of scale exist in Bangladeshi cropping system. Also, significant efficiency gains were made from diversification among cropping enterprises. The key policy implication is that crop diversification should be a desired strategy for agricultural growth in Bangladesh. Development of... |

The concept of pollution prevention, or "P2," signifies a new, proactive environmental mindset that targets the causes, rather than the consequences, of polluting activity. While anecdotal evidence suggests that P2 opportunities exist and that many have been pursued, there is also the perception that the pace of P2 is far too slow. To explore that claim--and to shed light on barriers to P2 innovation--this paper presents case studies of industrial P2 projects that were in some way unsuccessful. While based on a very limited sample, the evidence contradicts the view that firms suffer from organizational weaknesses that make them unable to appreciate the financial benefits of P2 investments. Instead, the projects foundered because of significant unresolved... |

The growing importance and scope of technology transfer processes undertaken all over the world settles the question of the necessity for their proper identification. The multi-aspect character and complexity of these phenomena create specific problems in conducting analytic work. Although technology transfer is an element of the Science-Technology-Innovation (STI) system, it does not have a proper place in the existing methodology system of this area. The aim of this article is to point out the necessity to create a proper, complex and comprehensive methodology for researching technology transfer processes, which would contribute to better understanding of the processes themselves and at the same time enable their proper development. |
