Farmers in the developing world frequently find themselves in uncertain and risky environments: often having to make decisions based on very little information. Functional models are needed to support farmers tactical decisions. In order to develop an appropriate model, a comparison is carried out of potential modelling approaches to address the question of what to grow where. A probabilistic GlS model is identified in this research as a suitable model for this purpose. This model is implemented as the stand-alone Spatial Decision Support System (SDSS) CaNaSTA, based on trial data and expert knowledge available for Central America and forage crops. The processes and methods used address many of the problems encountered with other agricultural DSS and SDSS. CaNaSTA shows significant overlap with recommendations from other sources. In addition, CaNaSTA provides details on the likely adaptation distribution of each species at each location, as well as measures of sensitivity and certainty. The combination of data and expert knowledge in a spatial environment allows spatial and aspatial uncertainty to be explicitly modelled. This is an original approach to the problem of helping farmers decide what to plant where.

Communication with an organisation’s customers has become one of the most important factors that play a role in doing business today. Organisations that supply their customers with correct and different kinds of information create customer loyalty. Dairy farmers are no exception to the rule, because of the ongoing planning that dairy farmers need to do on a daily basis. Dairy farming in South Africa is extremely price sensitive and therefore information that can help in decision making plays an important role in making the right decision at the right time. The Internet has become an essential environment where information is readily available to anyone who has access to the technologies, such as smartphones, computers and tablets. Thus, it will be beneficial for both the organisation and the dairy farmer to have relevant information available on the organisation’s website. The information that is made available to the dairy farmers on these websites needs to be updated on a daily basis. The information must be relevant to dairy farming and must provide additional information besides the information that the specific organisation specialises in. Information as a Service (IaaS) for Dairy Farmers in South Africa is the focus of this research. The purpose of the investigation is to provide a means of providing the information needed by dairy farmers in South Africa, to enable them to make the right decisions on an operational level. The empirical data were collected, analysed and interpreted. From these findings a proposed communications framework is created to assist organisations to better communicate with dairy farmers in South Africa. The purpose of this research study is to design a framework which will provide IaaS to dairy farmers in South Africa. The research determined the different ways in which organisations can communicate with dairy farmers and the best time period in which that communication should take place for each specific communication strategy. Therefore, the aim of the research study was to determine the best ways to communicate with dairy farmers. A clear knowledge of the technologies that dairy farmers use to manage information was determined by the research study. The required information that dairy farmers need to make the correct decisions suitable for the requirement of farming on a practical level was determined by the research study.The proposed framework on Information as a Service for Dairy Farmers could help organisations to supply dairy farmers with the right information at the right time. The proposed framework will assist organisations dealing with dairy farmers easier and will also assist farmers, because the information provided as a service will be relevant to dairy farming. The treatise is an exploratory, mixed method research study which consists of literature reviews, surveys and cross-sectional studies. Secondary resources was used to conduct literature studies to determine the information needed by dairy farmers. A questionnaire was compiled from existing questionnaires as well as from literature studies and was completed by the respective respondents in the dairy farming community. The survey also consists of questions that determine what dairy farmers think about the service they receive from the organisations that they deal with. A cross-sectional study was used to compare the information needed specifically by pasture-based dairy farmers in relation to total mixed-ration-based dairy farmers. Both Descriptive and Inferential Statistical methods will be used for the analysis of the data. The communication systems can vary from Self-Help Groups to Mobile Technology. The type of communication system will depend on the systems that the organisation have available for their customers. The timing of communication with dairy farmers needs to be convenient and depends, according to literature, on the type of social networking that the organisation might use. An organisation that deals with dairy farmers needs to decide which Social Media site is most suitable when it needs to communicate with dairy farmers. The technology used to access information consist of Laptops, Smart Phones, Tablets and Desktops. Agricultural organisations provide information which dairy farmers need, to give them the correct guidance in performing good farming practices in order to produce safe, high-quality milk. The study will conclude with the development of a proposed communications framework where agricultural organisations can provide information as a service to dairy farmers.

Over the past decade '"Sustainable Development" (SD) has emerged as the latest development catchphrase. A wide range of nongovernmental as well as governmental organizations have embraced it as the new paradigm of development. A review of the literature that has sprung up around the concept of SD indicates, however, a lack of consistency in its interpretation. More important, while the all-encompassing nature of the concept gives it political strength, its current formulation by the mainstream of SD thinking contains significant weaknesses. These include an incomplete perception of the problems of poverty and environmental degradation, and confusion about the role of economic growth and about the concept of sustainability. The purpose of this study was to identify common elements in a political economy of the environment, relating environmental change to the dynamics of ideology and policy, and at different levels of political complexity. The intention was to provide a structural analysis of the environment in which the development process illuminates environmental change at both a philosophical and material level. The problem in achieving SD was related to the overriding structures of the international economic system, which have arisen out of the exploitation of environmental resources, and which frequently operate as constraints on the achievement of long-term sustainable practices. Insufficient accounting of ecological aspects of economic growth and development has resulted from intellectual traditions, where solutions are formulated, point in different directions. Conclusions are drawn that SD involves trade-offs between biological, economic and social systems and is found in the interactive zone between these systems. There are a number of international factors that may be necessary, but insufficient, conditions for SD on a national level, including peace, debt reduction, and more propitious terms of trade. There was seen dilemmas relating to SD, including the role of growth as the unquestioned objective of economic policy.
