| There is growing evidence that freshwater availability is declining, while competition among sectors for the withdrawal of this scarce resource is rapidly increasing,(Rosegrant et a, 2002). Therefore, the need to promote inter-sectoral water use efficiency from the demand-side management has necessitated a study to investigate the responsiveness of different productive sectors and sub-sectors to water prices. Extracting data from the GTAP and UNIDO databases and adopting the marginal productive approach by Wang and Lall (2002),and using the two-stage-least squares method, the translog production function is estimated, from which the output and price elasticities and the marginal value of water is computed for thirteen sectors. The results indicate that... |

| The purpose of this paper is to investigate the role of trust in the performance of the sugar industry supply chain in Swaziland. The study utilized perceptions of 124 smallholder cane growers in the sugar industry in Swaziland. Items presented in a Likert type scale were used to measure cane growers trust in the millers. Descriptive statistics involving cross tabulation were used to determine the impact of trust on the performance of the cane growers, which in turn has an influence on the performance of the whole sugar chain. The results indicate that farmers who have trust in the millers perform better than those without trust, and hence they contribute to the performance of the whole chain, in terms of more and good quality sugarcane supplied to the... |

| This article examines a new role for contract farming in developing countries in the light of the industrialization of agriculture and the globalization of world markets. A theoretical rationale for contracting in developing countries is developed on the basis of adopting new institutional economic theory for the purpose of matching governance forms to market failure problems and transaction characteristics. The history of contract farming is reviewed, together with the advantages and disadvantages to the various players, for the purpose of developing a list of key success factors, problems and some possible solutions. |

| The introduction of genetically modified (GM) food products to food markets around the world, has led to considerable controversy. In many cases consumer attitudes and perceptions of GM food products were revealed as fears, concern for, and avoidance of the new technology. The importance of GM foods in South Africa is increasing, even though the GM Food debate lags behind many other (often more developed) parts of the world. This paper investigates the knowledge, attitudes and acceptance of urban South African white-grain maize consumers regarding GM maize. Conjoint- and cluster analysis were used to develop clusters/market segments among the urban consumers of white maize. A range of additional questions was used to develop profiles of the identified... |

| The theme of this conference provides an ideal opportunity to take this argument and the case I made for cross disciplinarity, a bit further. Last year I have argued that agricultural economists need to utilise the strengths of sociology, anthropology and political analysis in order to be better equipped to tackle the challenge of black empowerment in South African agriculture. This year I will show how we need these disciplines and also philosophy if we want to address 'ethics' in business. The point that was made throughout my earlier paper is that economic theory sacrifices far too much relevance in its pursuit of ever-greater rigour. Given the challenges in agricultural sector in Africa, we need to see much stronger efforts to integrate the building of... |

| Mohair is an exclusive natural animal fibre with niche market appeal. It is, however, questionable whether it is inherently suited to a commodity-based marketing system in a marketing environment that requires marketing systems to convey far more information than commodity-based systems do. Historically, mohair has been considered a commodity and the marketing system for mohair has been structured accordingly. It is, however, argued that, the exchange between mohair growers and the buyers of greasy mohair requires increased levels of coordination to govern the exchange in a transaction costs efficient manner. The inefficiencies created by an inappropriate or incomplete marketing system for South African mohair are expected to lead to a loss of consumer... |

| Abstract This paper investigates the competitiveness of small and medium-scale maize milling enterprises in South Africa from estimates of a translog stochastic cost frontier model. Results suggest that small and medium-scale maize mills in South Africa are cost-inefficient, operating at 59 percent and 30 percent higher cost than the best practice respectively. This implies that, on average, about 59 percent and 30 percent of the costs incurred by small and medium-scale maize mills respectively can be avoided without a reduction in maize meal output. Given this empirical estimates, if small and medium-scale maize milling enterprises in South Africa are able to reduce cost by 59 percent and 30 percent on average respectively, these mills could become... |

| With the emergence of private food safety and quality standards in developed countries fruit exporting countries in the developing world face increasing constraints to access markets in the rich industrialised countries in the North. Producers in the South have no alternative as to make the necessary investments on farms and in pack houses to comply with the requirements of these food quality and safety standards. The export of fresh fruit is an important component of South African agricultural exports, with citrus fruit exported to markets such as Europe being of particular importance. This paper reports selected results from a large research project into the impact of private standard compliance on the quality of the fruit and the returns to farmers. The... |

| A survey on food consumption patterns was conducted in an urban black community and a rural black community. Urban consumers tend to consume more bread, and less maize meal than rural consumers. Urban consumers consume more meat than poverty-stricken rural dwellers. The same is true with respect to fruit and ready-made foods. Both quality and price are important considerations for consumers' food purchases, particularly rural consumers. Price appears to be less important to the higher income (> R2000 per month) consumers in purchases of bread and meat, but rather important in vegetable purchases. Almost 60 per cent never consume food at away from home food establishments. |

| Through the Uruguay Round Agreement on Agriculture (URAA), the multilateral trade negotiations saw a turning point in the inclusion of agriculture in the trade liberalization debate. This development bears important implications for developing countries, including those of SADC, who have agricultural as a critical element of their economic growth, poverty alleviation, and food security. This article reviews the progress of SADC countries towards implementation of the URAA. We find that the extent of SADC countries support to the agricultural sector is still within the URAA provisions. However, despite certain preferential trade agreements in place between SADC and the developed world, trade barriers are still high in many developed countries. A... |

| This study examines the nature of the relationship between cane growers and millers and how it affects cane growers perceptions of the value added in the sugar supply chain. Drawing from relational exchange theory, the study utilised the perceptions of 124 smallholder cane growers in the Swaziland sugar industry. Factors measured in terms of a likert type scale were used to measure each relational construct within the miller-grower contract relationship. The unpacks the trust relationship between large agribusiness companies and smallholder out growers, and shows that relationships characterised by social factors like trust, commitment, and cooperation enhance mutual benefit and quality relationships between parties. This study found that farmers perceive... |

| The consumer price index was first used in 1707. In 1925 it became institutionalised when the Second International Conference of Labour Statisticians, convened by the ILO, promulgated the first international standards of measurement. These original standards have been revised three times and are currently under review. Statistics South Africa (StatsSA) compiles and disseminates different CPI aggregates, including the Consumer Price Index; the Core Index; CPIX; and the Food Price Index or CPIF. StatsSA has gone to considerable trouble in complying with international best practice in the calculation of the CPI. Nevertheless, three problems still remain, namely that StatsSA works with an unsatisfactory definition of rural areas, that no provision is planned... |

| This article analyses factors influencing farmers’ willingness-to-pay for dipping services, as well as the revealed preference for dipping frequency using the multivariate and the logistic regression models. The study is based on a cross sectional survey of 125 smallscale cattle farmers interviewed in the Venda region of the Northern Province. Empirical multivariate and the logistic regression analysis show that liquidity, human resource, satisfaction with the programme and structure of production significantly influences farmers’ willingness-to-pay. However, the most important factor influencing both the willingness-to-pay and the dipping frequency is liquidity (employment). The results of this study have important implications for the delivery of... |

| With South Africa’s urban population approaching 60%, supermarkets and fast food chains have become important players in the South African food system. These large players in the food sector have systematically modified their procurement practices especially with regard to fresh fruit and vegetables and are now circumventing spot markets in favour of sourcing via in-house sourcing companies who mainly procure from preferred supplier producers. This paper draws extensively from a global research programme which seeks to highlight the market changes that potentially contribute to continued exclusion of the small producers from mass consumer markets. This paper illustrates, through a series of case studies, how integration of small-scale farmers into the... |
