| This paper links two different methodologies to determine the effects of climate change on the Western Cape farm sector. First, it uses a general circulation model (GCM) to model future climate change in the Western Cape, particularly with respect to precipitation. Second, a sector mathematical programming model of the Western Cape farm sector is used to incorporate the predicted climate change, specifically rainfall, from the GCM to determine the effects on key variables of the regional farm economy. In summary, results indicate that future climate change will lead to lower precipitation, which implies that less water will be available to agriculture in the Western Cape. This will have a negative overall effect on the Western Cape farm economy. Both... |

| 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 paper models dairy farms in KwaZulu-Natal, South Africa, emphasising the complexities unique to this multi-product industry. Net and gross output approaches to measuring production are discussed and then tested using panel data from 37 dairy farms in KwaZulu-Natal from 1999 and 2007. Production functions for the three outputs: milk production, animals and farm-produced feed, are fitted as a simultaneous system to model the farms’ production activities. This simultaneous model is complemented by a single equation reduced form that is fitted as a frontier, which allows estimation of the relative efficiencies of the individual farms. The results show that, with data this detailed, it is possible to refine the model until it fits very tightly. Indeed, in... |

| The objective of this paper is to identify some of the salient characteristics of agriculture in the new millennium. The driving force behind economic change is technology and information, and information and knowledge will replace land, labour and capital as the sources of wealth in agriculture. The resultant cognitive-technical complex in farm production will lead to the true industrialisation of farming and thus placing the traditional family farmer at a distinct disadvantage. Technology developments combined with inverse population growth and ageing population, will not only negate Malthusian visions, but also lead to downward pressure on farm commodity prices, and thus increase the adoption rates of new technology. However, in reaction to the... |

| This article reports the results of a static computable general equilibrium (CGE) model on the possible liberalisation of agriculture and food trade in the OECD countries. Liberalisation of trade was simulated assuming a reduction in import tariffs, the tax rate on factor use and export subsidies in four steps of 25% points each. Such simulations were run in the GLOBE model then adjusted and used as a policy shock to the PROVIDE model. The results show that the weighed average world price (adjusted) changes will range between -19.6 to +3.8% for imports and between -3.0 and +29.7% for exports at 75% liberalisation. The results from the single country CGE model show that the South African economy would respond positively to the world price changes, with... |

| The working paper discusses the trends in farm employment over time in South Africa. This is followed by the presentation of six case studies of specific commodities and regions with the view to establishing the potential employment effects of various changes in the policy environment. The article ends with an assessment of selected aspects of the wider environment within which the sector operates, to ascertain the extent to which such policy shifts are feasible, i.e. whether the measured effects in employment generation are likely to happen. |

| Various institutions wanting to invest in agricultural production or the agribusiness sector in the SADC region need information on the quality and location of agricultural resources. Generating agricultural resource information on a regional level provides the challenge of integrating vast amounts of information from the various countries, implying storing, retrieving and manipulating it to determine areas best suited to grow a particular crop; or various crops that can be grown in a particular area. A Geographical Information System (GIS) has been developed as part of a broader project to assess the agricultural potential of SADC countries from a physical-biological-climatological point of view. Crop suitability maps obtained from the GIS containing... |

| This paper reports the results of an international comparison of the cost of producing wheat in 8 Western Cape, 3 Free State and 7 foreign producing areas. Results show that South African yields are low compared to foreign countries whose production costs are as high as or higher than those in South Africa, while the net margins for South African producers are less than a third of those for countries that have the same or lower yields as South Africa. If the wheat industry in the Western Cape is to survive international competition, it will have to create its international competitiveness. |

| This paper attempts to estimate the effects of some of the changes in the marketing system on the Western Cape Province of South Africa, utilizing a regional linear programming model of the agricultural sector of the region. The model includes supply, demand and production risk, and simulates the present agricultural production structure well. Market and trade liberalisation have major impacts on the structure of Western Cape agriculture, particularly the grain and livestock sub-sectors, with only marginal and mostly insignificant effects on horticultural products. |

| During 1997 research was conducted on trends in factors that affect the supply and demand for airfreight space for fynbos exports from South Africa. The aim was to sensitise decision-makers to probable trends in those factors that will shape cargo space availability. The main finding was that the supply of airfreight to South African producers is aggravated by the unbalanced availability of cargo space on southbound and northbound trips originating from Cape Town. If the price and quantity of cargo space were determined by supply and demand, an imbalance couldn’t arise in a perfect market, as prices would balance cargo space supplied and demanded. However, airfreight tariffs are rigid per weight level. The result is that items with a higher mass per volume... |

| The rise of supermarkets, together with large-scale food manufacturers, has deeply transformed agri-food markets in many countries. This expansion has been evident in South Africa as well. Increasing attention has been and is being paid to the growth of supermarkets in countries outside of North America and Europe. Numerous studies have been carried out in developing countries, including South Africa. However, these studies, while identifying the growth of supermarkets and the changes in supply chains, notably downstream, that have been caused by this growth, have made relatively little progress in documenting the impacts at producer level and in identifying issues that need to be addressed. There is a special need for studies on how farmers and supporting... |

| Traditional knowledge has been used, and is increasingly being used, in a wide range of industries for the development of new products. Increasing awareness of the economic value of biological diversity has resulted in industries seeking to exploit traditional knowledge and biodiversity through opportunistic behaviour (biopiracy). This is also happening in South Africa, where numerous industries are developing new products. Recent advances in the field of biotechnology have created the need for greater intellectual property rights protection. The protection of traditional knowledge has however long been ignored as developed nations and large industries have sought to promote self-serving systems of protection. In this paper the example of an indigenous... |

| The concept of capacity-sharing (as a specific type of demand-orientated water management strategy) is a relatively newcomer on the South African water management regime and much debate is currently under way regarding the viability of the concept for the South African context. One of the main features is that it decentralises and integrates water management to a much greater degree than state-dominated management regimes. However, as the concept of capacity-sharing allows a greater degree of decision-making autonomy to the private decision-maker, the question could be asked to what extent the management of a capacity-sharing regime would be exposed to opportunistic behaviour from private irrigators. If it is heavily exposed, there are considerable scope... |

| In a context in which the framework of agricultural policy and business is changing radically the objective of the government and farmers should be to support the development of systems that look likely to be winners in the future. As a result this paper uses a Policy Analysis Matrix (PAM) to determine whether wheat production would have a comparative advantage if produced under organic practices. The paper starts by analysing the comparative advantage of wheat under conventional practices, and later contrasts conventional with organic practices. The results of the analyses mainly indicate a comparative advantage for wheat grown under organic practices especially when the social cost benefit ratio (SCB) is incorporated into the analyses. This is because... |
