The construction of the Southeast city district in Uppsala will start in 2025 with plans to be completed in 2050. When a new district is built, there is an opportunity to explore the best possible solution to all the needs of the city, one of the needs that must be met is the heat demand of all buildings. One possible way to meet these needs is through district heating. The aim of this report is to design and investigate the efficiency of a heat distribution network in the Southeast city district by determining its distribution losses and the requirements that heating distribution networks must fulfill. The method used to satisfy the purpose is to simulate the systems through a model in Python. The model produces key parameters such as distribution losses, pressure drop and temperature drop during high heat demand and low heat demand. The results of the report shows what a possible distribution network design could look like for two stages of construction. It is also shown that during low heat demand, the highest distribution losses were in the return pipe. During the high heat demand, the highest distribution losses were in the supply pipe. This is also the period of the greatest mass flow rate, temperature drop and pressure drop. The discussion addresses the correlation between these parameters as well as exploring how connecting an additional building stage impacts the performance of the system. The conclusions of this paper is that the designed distribution networks fulfill the necessary criteria for pressure, temperature and energy delivery with acceptable distribution losses. When a additional stage is connected to the system, distribution losses do not increase significantly, making the model suitable for future extensions of district heating networks.

The main objective of this study is to examine the potential contribution of households’ involvement in mopane worm activities (harvesting, commercialisation and consumption) to households’ food security in the Mopani District of the Limpopo Province. Data was collected using a structured questionnaire from a stratified sample of 120 households, 60 of which are mopane worm harvesters. The Binary Logit Model was used to determine households’ socio-economic factors affecting participation in mopane worm harvesting. The results revealed that gender of the household head, age of the respondent, households’ size and the level of income per month increases the probability of households participating in mopane worm harvesting whilst distance to the market and food expenditure as well as religion (belonging to the Zion Christian Church) decreased the probability of being mopane worm harvester. The Ordinary Least Square (OLS) model was used to identify households’ socio-economic factors that determine the rate of commercialisation of mopane worms within harvesting households. 53 percent of the households commercialized their harvest. The model identified that gender, harvesting experience and income from mopane worm sales are the main factors determining commercialisation within harvesting households. The Household Food Insecurity Access Scale (HFIAS) was used to determine household food security status. The result revealed that about 20 percent of the harvesters were food secure, while 80 percent where food insecure. In addition, about 12 percent of the non-harvesters were food secured. An OLS model was also used to examine the impact of mopane worms in the food security status of the households in the Limpopo Province. The results revealed that age, education level of a household head, level of income, income from mopane worm sales and frequency of consuming mopane worm/day improve the food security status of households whilst households’ size and the distance to the market worsens the food security status of the households. The study found that about 48 to 60 percent of the households to be adopting less pervasive strategies like asking neighbours/family relatives for help, borrowing money for food and selling mopane worms for cash to protect their food consumption and over 70 percent adopted strategies like reducing food intake, portion size and eating less preferred food were adopted to modify their food consumption. The findings indicated that policy priorities should be focused on the promotion of harvesters associations for collective marketing and creating an enabling environment for sustainable harvesting and commercialisation. / M.

A quantitative approach was used to investigate the stigmatization of HIV positive clients in the Leribe District of Lesotho. The study population included 5200 HIV positive patients who enrolled for ARV in government clinics. A randomly selected sample of 520 clients responded through a questionnaire and interviews. The statistical package (STATA version 9) was used to analyze data. The objectives of the study were to explore the type and level of stigmatization of HIV-positive clients and to describe ways in which health workers in the PHC can reduce the stigmatization of HIV-positive clients at the clinics. The findings revealed that types of stigmatization included separation, isolation, labeling and discrimination. Ways to reduce the stigma within a community based primary health care facility included educating people living with HIV on how to protect themselves from multiple infection, providing effective counselling to clients and families maintaining confidentiality, and using change strategies to change attitudes of health care providers. The integration of HIV-related activities is a strong recommendation and the importance of the consistent availability of ARV treatment was emphasized. / Public Health / M.A. (Public Health)

The objective of this thesis is to examine the need for people and communities to develop liquid assets through a savings programme and to work productively with these savings. It had to be taken into consideration that at least some members of the population could be considered non-monetary in their orientation. In order to achieve this objective a participatory and culturally sensitive micro-finance programme was designed through an Action Research methodology. By combining mainly quantitative baseline information, detailed and more qualitative work with some of the participants and routine output from the programme activities, the study aimed to arrive at concrete conclusions concerning the way a micro-finance programme has worked in San conununities and make recommendations regarding its future. lt was found that the programme has made at least some of the participants more conversant with the handling of cash and also contributed to increased self-respect. Developing liquid assets was most difficult for the poorest participants and the majority of these poorest are women. The San people are the poorest; even among other marginal rural minorities and should receive special assistance. The programme was moderately successful in helping participants to save towards larger needs and to even out income flows. It could not be established whether the programme could make a contribution to the development of long~term assets. Initiatives to establish microenterprises with the capital met with only limited success. The programme was not successful in establishing a savings programme as an alternative to cattle farming and should rather be seen as a complementary strategy for increasing household assets. It was found that the emphasis on savings mobilisation, rather than the creation of debt through credit was valid. Increased incomes will lead to increased indebtedness. A higher influx of cash in a San community is likely to be unevenly spread and is also likely to increase the gap between the wealthier and poorer community members. It was concluded that projects that meet basic and immediate needs such as food, shelter and housing, should be integrated with programmes that address larger needs such as loss of culture and land. A process of empowerment cannot be supported when rural poverty is not addressed. / Development Studies / D.Litt. et Phil. (Development Administration)

The study sought to analyse teachers' level of knowledge, attitude and preventive practices in relation to HIV/AIDS in Petauke district in the eastern province of Zambia. The study sought to determine whether teachers were well informed about HIV/AIDS, had no discriminative behaviours towards HIV/AIDS-affected people, and finally whether their preventive practices were good in relation to HIV/AIDS. The major inferences drawn from this study are that teachers are well informed about HIV/AIDS and that their attitudes are mostly non-discriminative. Preventive practices were found to be good but contradictory to the reality on the ground. / Health Studies / MA (Public Health)

Too often, literature on participation in community development is void of the rationale for the participation of teachers; the roles they may play; factors for and against their participation; and strategies for inviting and sustaining their participation. This study examines what could be done to ensure the participation of rural based teachers in community development activities, by exploring these issues. A qualitative design and purposeful sampling are used. The sample consists of information-rich informants from the following five categories: officials of the Rural District Council, non-governmental organisation workers, rural based school teachers, Village Development Committee Chairpersons, and ordinary community members. Interviewing is used as the major instrument of data collection. The study reveals that rural based teachers should participate in community development activities, since they have a wide knowledge base and transferable skills, and they are part of and trusted by the community. It reveals that rural based teachers' participation is deterred by political factors, lack of supportive policies, attitudes, conservativeness, lack of specialized training, and labour issues. Twenty two roles are identified for rural based teachers in community development activities. Strategies for inviting them to participate are: the use of policy, change of attitudes, use of media campaigns, training, and inclusion of community development in tertiary education in general, and teacher education in particular. Strategies for sustaining their participation emerge as: the use of incentives, free time or days off and holding responsible offices. Sixteen recommendations are finally presented. / DEVELOPMENT STUDIES / MA (DEVELOPMENT STUD)
