- Description: Production functions are common to any productive activity. Although it may not appear obvious, cricket is no different. Production functions in cricket provide a wide range of information, utilised to enhance efficiency and maximize match success. Given these benefits, this study involved the derivation of a production function for the South African SuperSport Series and an analysis of technical efficiency. An econometric analysis was conducted on data from the 2004-2011 cricket seasons and it was concluded that the most optimal strategy for South African teams involved a combination of attacking batting and defensive bowling. Furthermore, South African teams had a relatively low variable substitutability and a high degree of technical efficiency.

- Description: Tanzania’s energy consumption is dominated by biomass, most of which is consumed by households. Apart from biomass, the country has extensive hydropower, coal and natural gas resources. The overwhelming dependence on biomass for basic cooking and heating needs by the majority in Tanzania, is a major cause of poverty and several other deleterious effects. As a consequence of the harmful effects of fossil fuels, biofuels are seen as a source of sustainable growth to help alleviate poverty in Tanzania. In this chapter, present policies and other framework conditions influencing the development of the biofuel sector in Tanzania are investigated. This includes the Tanzanian Energy Policy, Land Act, National Forest Policy, National Environment Policy, Agricultural Sector Development Policy, and the Tanzanian Transport Policy. The necessity for policies directly related to biofuel production is discussed. The Tanzanian government has established a Biofuels Task Force (BTF) in order to produce guidelines for the design of a set of appropriate policy initiatives. Due to the lack of formal biofuel policies, several external agencies have made recommendations on policies that the Tanzanian government should adopt. It is concluded that the policies existing in Tanzania are indirect and thus biofuel producers lack a reliable framework. Due to increasing biofuels, especially amongst small-scale farmers, the government must seek to provide these smallholders with incentives to grow their productions along with large-scale producers.

- Description: Increasing awareness of the environmental damage caused by the existing fossil fuel-based energy system and rising fossil fuel prices explain, in part, the growing interest in renewable energy sources. In March 2008, oil broke through the psychological ceiling of 100 US$ a barrel, and later in early June 2008 rose to 140 US$ on the way to 150 US$. In addition, rising issues on global warming have resulted in the need to consider alternative sources of energy. This also resulted in debates about biofuels in most developing and developed countries. Zambia is faced with an energy crisis from importation of large amounts of crude oil and the high cost of fuel and petroleum products. Sweet sorghum has been flagged as a potential biofuel feedstock in Zambia. This chapter evaluates different varieties of sweet sorghum and identifies production scenarios under which sweet sorghum can be produced in Zambia by the use of Gross Margin Analysis. It also evaluates notable trade-offs in producing sweet sorghum instead of grain sorghum. The results show that identifying high sweet sorghum yielding varieties and optimum production scenarios are important pre-requisites for the successful implementation of the use of sweet sorghum in biofuel production. The results indicate a positive relationship between the yield of sweet sorghum and the production regime.

- Description: The feasibility of springbuck based meat production in the Eastern Cape Karoo was analysed through a stochastic budgeting model, while openly taking cost and price risk into consideration. Monte Carlo simulation of a springbuck-based meat production enterprise was used to quantify the risks that would be faced by springbuck ranchers. Springbuck ranching has been proven a viable alternative in the production of highly nutritious and healthy meat (venison) that is in high demand in European markets and more recently, with a promising and increasing local demand as well. The results indicate that in the Eastern Cape Karoo, springbuck ranching for meat production is a viable business. As the call for more environmentally friendly rangelands utilisation economic systems intensifies, rangelands owners in the Eastern Cape Karoo have a practicable option. At the very least, an alternative to broaden their incomes with springbuck-based meat production exists.

- Description: In the age of trade liberalisation and globalisation, the world markets are increasingly being integrated. This implies that farmers in the developing world are ever more linked to consumers and corporations of the rich nations. Consequently, local farmers are facing increasing market competition, not only in international markets but in local markets as well. In an effort to withstand the market pressures, agricultural markets are now transforming to a vertically coordinated structure (Reardon and Barrett, 2000). In addition, both the private and the public sectors have made some adjustments in agricultural markets, in order to survive competition resulting from market changes.

- Description: [From text] What is Institutional Economics? Before delving into the concept of institutional economics, it will be useful to explain what is meant by institutions because institutions in economics have a particular meaning. The most commonly agreed upon definition for institutions is a set of formal and informal rules of conduct that facilitate coordination or govern relationships between individuals or groups. The formal rules include laws, contracts, political systems, organisations, and markets, while the informal rules of conduct consist of norms, traditions, customs, value systems, religions and sociological trends. Institutions provide for more certainty in human interaction (North, 1990) and have an influence on outcomes such as economic performance, efficiency, economic growth and development. They can either benefit or hinder these economic measures. Williamson (2000) noted that new institutional economics operates at both the macro and micro levels. The macro level deals with the institutional environment, or the rules of the game, which affect the behaviour and performance of economic actors and in which organisational forms and transactions are embedded. Williamson (1993) described it as the set of fundamental political, social and legal ground rules that establish the basis for production, exchange and distribution. The micro level analysis known as the institutional arrangement, on the other hand, deals with the institutions of governance. These refer to the modes of managing transaction costs and include issues of social capital, property rights and collective action. Here the focus is on the individual transaction and the questions regarding organisational forms (private property versus common pool resources) are analysed. An institutional arrangement is an arrangement between economic units that govern the ways in which its members can co-operate or compete.

- Description: A framework has been established to determine the economic impact of contaminated fertilizer on pineapple growers in the Eastern Cape. Farmers in the region unwittingly made use of contaminated fertilizer which infected pineapples with higher than permissible levels of the heavy metal toxin, cadmium. The fruit was deemed unfit for use, translating into large financial losses for growers and influencing all participants in the industry. The pineapple trade was devastated. Pineapple production costs and revenues are adapted from previous studies as much of the necessary data was sub judice because of the pending legal action. Despite the problems with data, it was established that the farming operations were severely compromised because of the contamination.
