Abstract: Lack of access to electricity grid form the main challenge facing majority of developing regions particularly in rural communities. The situation is driven mostly by the absence of electricity infrastructure in most of the developing countries particularly in rural communities. A number of developing countries are now encouraging the use of solar home systems in isolated areas. Botswana is not immune to this trend. Consequently, available evidence puts the overall contribution of solar energy to primary energy supply in Botswana to less than 1%. A plethora of factors are responsible for inhibiting rapid development of solar home systems in isolated areas in Botswana. Some major impediments often cited as causing low use of solar home systems by rural communities in Botswana include, among others, the following: (i) Low-income status of most rural inhabitants. (ii) Migration of house-owners from village status to lands, or cattle posts. This paper, therefore, analyses factors that impede the rapid development of photovoltaics power generation systems in rural environments in Botswana. The analysis is based on photovoltaic power generation pilot project which was carried out in three (3) villages in Botswana, namely Kudumatse, Lorolwana and Motlhabaneng.

Abstract: This paper is the outcome of students'project guided by the author. An attempt has been made to design and develop a solar still for rose production in India. This unit has the following features:i) possibility of tilt adjustments to suit different altitudes of sun,ii) specially designed steep basin for conveniently keeping the rose petals and water in an inclined position and iii)cover which can be opened to facilitate the cleaning operations. This unit supplied 3.7 litres of rose water in three days during winter in Madras, in India. The sunshine and solar radiation particulars of Botswana are shown to indicate that a better climatic conditions prevail here for a higher production rate.

Abstract: In many African countries, including Botswana, the driving schools and instruction given to pupils are uncontrolled. Thus, this paper presents the results of an investigation into the level of professional training offered by the driving schools in Gaborone. A total of 400 randomly selected drivers completed questionnaires on their training, accident records, and L-tests. Male trainee drivers received more instruction than females, and there was some indication that the pass rate on L-tests was lower for female drivers. Also, the pickup van forms the majority of the national vehicle population. It accounts for almost 40% of the accidents but is presently not used for training in the commercial driving schools. It is concluded that the quality of professional instruction in driving schools needs improvement so that learners can be encouraged to take training from these institutes.

Abstract: Formal Engineering Education has traditionally been delivered using the low technology—high touch lecturing method, in which the lecturer and student meet face to face. Distance education in this field has been quite slow to develop primarily because of difficulty in delivery of practical based instructions and problems on integrity of assessments. Developments in information technology and the increased demand for further education by people already in employment have however changed this even in developing countries. It puts extra demand on Lecturers to guide distance learners in handling numerical computations so prevalent in Engineering. At the campuses, computer based methods are available in the high touch—high tech lecture method. High level and efficient computer software is used to help the student to simulate and solve some problems. However, such software is expensive—and therefore—not readily available to the distant learner. Spreadsheets on the other hand are almost universal on today’s computers and they bridge the gap between hand calculations and high level programme computations. This paper therefore makes a case for the use of spreadsheets in Distance Engineering Education. An example in Spring Design, Selection and Adaptation is used to illustrate the simplification and other advantages of their use by practicing distance learners.

Abstract: There is little in-depth research that can assist designers to use culture as a catalyst for designing innovative products within Botswana’s context. This is supported by evidence from the literature which indicate that from an African perspective, there is no solid theoretical framework which can assist designers to consciously integrate users culture in designing products. This challenges designers to gain a deeper understanding of users culture and find strategies on how they can use culture as a resource in product development. The concept of culture and design are intertwined, thus modification in the former evolution both reflect and determine developments in the latter. For example, design changes culture and at the same time is shaped by it. The paper discusses an experimental design study conducted at the University of Botswana. Participants were challenged to transform a set of socio-cultural factors and encode them into recognised product design features that reflect Botswana's culture. The data generated by participants was analysed using the qualitative content analysis methodology. The paper concludes by discussing a culture-oriented design model which has shown one way on how to consciously specify, analyse and integrate socio-cultural factors in the early stages of the design process. The design model challenges the way products are designed for different cultures and supports the use of local content in solving design problems.

Abstract: Public support for source separation schemes in developing countries is still subject to continuing debate and limited work has been directed at understanding its manifestations. The purpose of this survey was to assess existing and potential levels of household participation in waste source separation as well as establishing the role they could play in future source separation schemes in Gaborone. Questionnaire based surveys were used to elicity information from households about their awareness of recycling and recycling initiatives, attitudes and willingness to participate in source separation schemes. The survey involved 17 households who participated in a pilot source separation scheme and 284 households who did not. The results showed that the majority of households are aware of recycling and recycling initiatives, but this awareness does not necessarily translate into participation in recycling activities in the absence of incentives and visible systems. It was also found that the majority of households are willing to participate in future source separation schemes, however, such willingness was primarily limited to separating materials that at the time had known available markets and were easy to separate.

Abstract: The Project Management Section at the University of Botswana has been undergoing a test to transform the section from an education based faculty to a research based faculty. The test was initiated by a Fulbright Scholar (FS) from the Performance Based Studies Research Group (PBSRG), bringing a new research model, a new risk management (RM)/project management (PM) model, and a concept of a research based graduate education that had been very successful at PBSRG. They proposed increasing the level of research activity of the UB PM section by merging the graduate MPM program and the industry research effort. They proposed using a research based graduate program, treating the graduate students from industry as a resource instead of a student, and their organizations as a potential testing laboratory. The mechanism to make the effort a success is the very powerful technology of the Performance Information Procurement System (PIPS) and the deductive logic of the Information Measurement Theory (IMT). This paper captures the case study results and future potential of the concept, highlighting the operational model to sustain the research platform in an underdeveloped country in a resource starved environment.

Abstract: The single-stroke ram press machine is widely used for sunflower oil extraction in African countries. It is manually operated, low speed machine constructed on the basis of slider-crank mechanism. The paper presents a detailed theoritical analysis of the mechanism of the linkage system. The analysis is done for different positions of the driving lever (handle) nad other parameters, which influence the performance of the machine. Based on that analysis conclusions on the optimal performance of the mechanism are drawn. URI: http://hdl.handle.net/10311/667 Files in this item: 1

Abstract: Solar energy is finding wide application via several energy-saving devices and systems. Its use, especially in rural areas, can often be limited by the non-availability of complete information on insolation data. In this investigation, both the mean extraterrestrial and terrestrial radiations were calculated for three zones in Nigeria. These zones were assumed to be dependent mainly on the latitude, L. The isotropic model was employed for the computation of the diffuse and ground reflected components of radiation. Consequently, the total insolation was obtained for various inclinations of the collector surface. It was found that three solar energy seasons exist for each zone. For maximum total incident radiation, a different collector inclination is ideal for each solar energy season. However, for all year round applications, a fixed inclination varying between L and (L+10) degrees is recommended. URI: http://hdl.handle.net/10311/672 Files in this item: 1

Abstract: “Sustainable development” as a concept was popularised by a 1987 report of the United Nations World Commission on Environment and Development. The report defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”. However, from this definition, we cannot ascertain the central intuition of the notion of sustainable development. Failure to do this makes it difficult to derive methods that can be used to formulate effective intervention policies that can enable nations to attain sustainable development. This paper briefly reviews various schools of thought in popular literature on the notion of sustainable development, exposes their weaknesses and develops a holistic notion of sustainable development based on the systems approach.

Abstract: This paper explores the extent to which recent social, economic, demographic and environmental changes in Botswana have enabled women to inherit land, housing and other household assets. Using qualitative data from a study undertaken in the peri-urban village of Tlokweng, the paper notes that, unlike in the past when women were largely excluded from property inheritance, the majority of parents who participated in the study on which this paper is based are now more inclined and willing to share their estate equally among all their children or to favour daughters over sons in deciding who should inherit residential properties. The changes, which are heavily contested by older women, young men and teenage boys, appear to have been due primarily to increased numbers of female heads of households and the role played by unmarried daughters in developing the family estate and caring for the aging parents.

Abstract: The lack of 'ubuntu'(African group solidarity) between project stakeholders in the Southern Africa Development Community (SADC) public building sector has been surrounded by controversy and strongly held opinions. The work reported in this paper attempts to indicate some salient issues affecting the relationshps between project stakeholders. The Botswana public building sector is used as a main case study and follwo-up studies are carried out involving another eight SADC countries. The paper addresses two propositions.First, that the lack of 'ubuntu' between project stakeholders is primarily due to an inappropriate project organizational structure.Second, that a default traditional construction procurement system (TCPS) provides a poor relationship management system. Information is obtained on the research areas through questionnaires to confirm executives, contract managers, site managers, trade foremen and skilled tradeperson on the dominant procurement system used in Botswana. Furthermore, senior technical officers of Public Works Ministries of another eight SADC countries are interviewed as a follow-up to the Botswana study. The primary conclusion to be drawn is that the building procurement system purported to be in use in the SADC public building sector differs significantly from that recommended in the theory, resulting in poor relationships between project stakeholders. This is primarily due to the use of inappropriate building procurement systems. In general, the TCPS in the SADC public buiding sector is used as a 'default system.' This has led to a situation where project management is a 'firefighting' activity, where group solidarity between project stakeholders is out of reach. Salient steps are proposed with proviso that the SADC public building sector should establish appropriate methods of selecting building procurement systems as a prerequisite in formulating appropriate project organizational structures which will bring the spirit of real co-operation between project stakeholders towards project success.

Abstract: With increasing internationalization of urban planning throughout the twentieth century and in the past several decades in particular, planning ideas and practices have been exported from a few, and imported in many countries. However, this ‘trade’ happens without clear expectations about the ensuing dynamics between the internal context and external influences. This paper attempts to enhance understanding of how planning systems evolve and which factors affect them. The conceptual frameworks and typologies used to characterize planning systems and their determinants are reviewed. Building on previous work, an integrated framework is proposed that captures the process, factors and outcomes of urban planning systems. The history of planning in Serbia and Montenegro is used to illustrate how a planning system evolves under changing circumstances and influences and to demonstrate the complexity of such process. The case study is not intended to provide a detailed historical account of the country’s planning trajectory, but to highlight the applicability of elements of the framework in a real setting. In particular, the focus is on conditions of imposition versus voluntary adoption of planning ideas as a way of examining the interaction between the local context and imported models, as well as the implications of such interaction. The article concludes with several pointers about the necessary research on the nature of planning exports and imports and their effects on the resultant urban systems, processes, environments and quality of life.
