    Industrial symbiosis in Tanzania: A case study from the sugar industry
    (Taylor & Francis Online, 2020) Rweyendela, Amani G.; Mwegoha, William J. S.
    The concept of industrial symbiosis (IS) offers enormous potential for more sustainable manufacturing processes. This paper sets out to explore the IS forms occurring at a case study of the Kilombero Sugar Company Limited (KSCL), the largest sugar refinery in Tanzania; and identify the underlying factors based on the data collected through key informant interviews, observational site visits, and relevant documentary reviews. Findings reveal an evolving IS network at KSCL involving physical exchanges of bagasse, molasses, filter cake, and boiler ash and utility sharing among seven co-located units. Through these modest internal IS arrangements, KSCL has optimized resource use, thereby minimizing negative environmental impacts inherent from emissions, as well as generating additional revenues from resource recovery, in particular the alcohol distillery unit. Results also show that KSCL’s industrial ecosystem is fragile due to limited functional and structural diversity. We identify several drivers and barriers as possible leverage points. The lessons from KSCL are expected to provide a valuable reference for IS development in Africa.

    Community perceptions on climate change effect and household food security in Karatu District, Tanzania
    (Mzumbe University, 2019) Kyusilu, Jacqueline
    This study assessed community perceptions on the effects of climate change and household food security in Karatu District, Tanzania. Climate change is leading to occurrence of events like precipitation and temperature changes, strong winds and occurrence of pests and diseases which have negative effects to crops growth. The study specific objectives were to examine community perception on climate change, to determine the effects of climate change on household food security, to determine the adaptation measures applied towards the effects of climate change to household food security and to examine the mitigation measures applied by household to reduce the impacts of climate change. Data were obtained through interview with key informants from the government, and a questionnaire used to interview households from small scale farmers of Ganako and Rhotia Wards in Karatu District Council. The findings show that community perceived there was changes in precipitation and temperature, occurrence of strong winds and emergency of weeds and insects destroying food crops. Perception of most of the respondents was that climate changes were due to anthropogenic causes and their effects led to the decline of food production and the status of food security to most of the household is low. The adaptation measures applied for climate change effects, were the adaptation of good farming methods that help to raise food production. Mitigation measures applied were raising awareness on environmental protection and conservation to reduce impacts of climate change in order to decrease the effects of climate change to household food security. The anthropogenic climate change effects led to food insecurity, although there were different adaptation and mitigation measures applied to address effects of climate change to food security but the results are not remarkable. Thus, it is important for the government and stakeholders to study community perception on climate change effects, to understand community challenges related to climate effects to household food security, and the findings can be used to improve national policies and viii legislations related to climate change and food security, like climate change strategy in Tanzania.

    An assessment of beach management units in combating illegal fishing in Lake Victoria, Tanzania: a case of Bukoba district
    (Mzumbe University, 2013) Kashililika, Edwin Wakisa
    The study is about an assessment of the Beach Management Units in combating illegal fishing with specific reference to Bukoba District. The aim of the study was to identify factors leading to ineffective performance of Beach Management Units in combating illegal fishing in Lake Victoria, Tanzania. Ninety-six (96) respondents were interviewed using structured questionnaires also information collected from a fishery official at District and Regional level by focused group discussion. Descriptive data were analyzed by the descriptive analysis method and SPSS 20 version and presented in frequencies. The findings revealed that the performance of the BMUs is poor because of, lack of boats for patrol (fishery patrol vessel), lack of source of revenue, difficult to get information about illegal fishing, BMUs leaders were found to be part of illegal fishing, also intimidation to BMUs’ leaders by big fishers who practiced illegal fishing and lastly voluntarism nature of work demoralizes the BMUs leaders to concentrate in combating illegal fishing. Given the above-mentioned reasons fueling illegal fishing, this study recommends local and Central Government to support the BMUs to improve its performance to achieve the sustainable and equitable exploitation of fishery resources. The basic support recommended include: Adequate funds to support their operations including the purchase of the fishery patrol vessel, awareness raising/sensitization to local authorities and community living along Lake Victoria shores on the importance of these Community-Based Organizations in combating illegal fishing, the impact of illegal fishing and how to provide information to the BMUs leadership about illegal fishing.

    Institutional factors contributing to ineffective monitoring and evaluation of public projects implemented by municipal officials in Kinondoni District, Tanzania
    (Mzumbe University, 2018) Joel, Nashon
    Effective and efficient Monitoring and Evaluation (M&E) is a necessity for the successful realization of the objectives of the municipal projects. Despite the recognition of the importance of M&E in enhancing the realization of expected project outcomes, quite often municipal official in most LGAs fail to meet their potentials in monitoring public social projects for unknown reasons. This study explores institutional factors contributing to ineffective monitoring of public projects implemented by municipal officials in Kinondoni District. The study employed a descriptive, case research design. A mixed research approach was adopted in which qualitative data feature more than quantitative ones. The tools for data collection included interviews, questionnaires as well as documentary reviews. Both, probability and non-probability techniques were utilised towards selecting a sample size of 120 officials from all the 12 departments and 4 sections of the Kinondoni Municipality. While thematic analysis was utilised in analysing qualitative data, descriptive analysis was employed towards analysis of quantitative data using measures of central tendency such as mean and standard deviation through a Software Package for Social Science (SPSS) version 20, and presented by using tables and figures. In the light of the study findings, the study revealed that municipal officials were knowledgeable and had capabilities of conducting M&E practices. However; due to various factors such as unavailability of resources, socio cultural factors, poor means of effecting strategies, as well as low perceived self efficacy towards meeting targets, their capabilities were constrained. Based on the findings, the study concludes that both, individual and institutional factors contribute significantly in execution of M&E activities at the municipal level. However, institutional factors surpass the individual factors. Notably, regulative factor was a leading institutional factor compared to others in limiting the capabilities of municipal officials in undertaking M&E. The study ends by recommending several regulative and cognitive measures to enhance effective engagement of municipal officials in undertaking M&E. Among others include institutionalization of M&E framework and establishment of legal framework for effective and efficient execution of M&E practices. Further, it calls for review of Local Government Reform Programme of 1998 to address institutionalization of M&E framework and establishment of legal framework for effective and efficient execution of M&E practices.

    Contribution and challenges of mangrove conservation to community’s well-being in eastern Tanzania
    (Smujo International, 2023) Ngowi, Norbert J.; Zakayo, Gideon
    Contribution and challenges of mangrove conservation to community’s well-being in eastern Tanzania. Intl J Bonorowo Wetlands 13: 15-21. Several mangrove conservation programs have been implemented in Tanzania to reverse degradation of mangrove ecosystem in the country. However, after their introduction in 1990s, many small-scale farmers relying on the mangrove ecosystems lost their livelihoods. To ensure that the people’s well-being and ecological integrity of the mangrove ecosystem are sustained, this study investigated the impact of nature conservation practices on financial sustainability, food security of local communities as well as ecological integrity of the mangrove ecosystem. The study employed a mixed-method approach where a survey was used to collect quantitative data from 90 household respondents selected randomly for a questionnaire survey. This was supplemented by data collected through personal observations and interviews administered to 30 local people (mainly key informants and focus group discussion). Quantitative data were analyzed through crosstab IBM SPSS version 20. Qualitative data were analyzed using content method. The results indicated that the conservation practices introduced brought a significant difference in financial stability (p<0.05) by increasing incomes of the implementing households to US $80.29 compared to US $69.20 for the non-implementing households. However, 83% of the implementing households still faced food insecurity by having meals only twice daily, although it was slightly higher compared to 80% for the non-implementing households. The 85% of the implementing and 65% of non-implementing households perceived that the conservation practices had improved the ecological integrity of the mangrove ecosystem by increasing the vegetation cover. The results of this study suggest that conservation practices in the mangrove ecosystem have increased financial sustainability and ecological integrity but failed to enhance food security. This study recommends the integration of rights of local communities on usage of land for paddy and fish farming to achieve sustainable economic growth in the estuary.

    Assessment of surface water quality near municipal solid waste dumping facility in Bukoba, Kagera Region, Tanzania
    (Wiley Online LIbrary, 2023) Lema, Meserecordias W. J.; Mwegoha, William J. S.
    Water samples were collected from River Kanoni which passes near a municipal solid waste (MSW) dumping facility in Bukoba Town, Kagera Region, United Republic of Tanzania. The objective of the study was to assess surface water pollution caused by a MSW dump. Selected physico-chemical parameters (pH, temperature, Electrical Conductivity [EC], and Total Dissolved Solids [TDS]), nutrient levels, as well as heavy metals concentrations (Pb, Zn, Cu, Cr, Cd) were analyzed in the laboratory at the University of Dar es Salaam, in accordance with standard methods, and were compared with the existing standard limits for freshwater qualities, as stipulated by WHO and US-EPA. Results have shown that pH values were within the allowable range of between 6.5 and 8.5, except for one value (8.82 ± 0.11) that was measured at the midstream. Temperature values were between 26.28 ± 1.02°C and 28.35 ± 0.15°C, which are within the allowable range of between 20°C and 50°C. EC values were between 262.50 ± 8.32 μS/cm and 345.01 ± 6.48 μS/cm, which are below the maximum allowable value of 400 μS/cm. TDS values were between 183.75 ± 6.55 mg/L and 241.51 ± 11.33 mg/L, which are below the maximum allowable value of 500 mg/L. Nitrate levels were between 17.52 ± 1.12 mg/L and 32.00 ± 3.02 mg/L, which are above the standard limit of 10 mg/L above. Concentrations of Lead, Chromium, and Cadmium were between 0.03 ± 0.01 mg/L and 0.16 ± 0.05 mg/L, 0.55 ± 0.02 mg/L and 1.14 ± 0.07 mg/L, and 0.009 ± 0.12 mg/L and 0.098 ± 0.22, respectively, which are all above the recommended limits of 0.01, 0.05, and 0.003 mg/L, respectively. Values for copper and zinc were between 0.02 ± 0.12 mg/L and 0.20 ± 0.22 mg/L, and 0.79 ± 0.32 mg/L and 1.57 ± 0.04 mg/L respectively, which are below the recommended limits of 1.3 and 5 mg/L, respectively. This study has revealed that Bukoba MSW dumping facility has potential impacts on the water quality in River Kanoni, for domestic usage. This, therefore, demands all relevant authorities to immediately find a proper and sustainable replacement for the existing MSW dump in Bukoba town.

    Emerging and persistent challenges in water resources governance in rural Tanzania: the Mgeta subcatchment of the Upper Ruvu Basin
    (Taylor & Francis Online, 2022) Theodory, Theobald Frank
    The article examines the emerging and persistent challenges of water resources governance that contribute to unequitable sharing of water resources amid the different competing users in the Mgeta subcatchment in the Ruvu River Basin, Tanzania. The author used a mixed method research design to examine the challenges of water governance in rural Tanzania, with a focus on households (water users) in the Mgeta sub catchment of the Upper Ruvu Basin. Focus group discussions and key informant interviews were used to garner qualitative data, while a questionnaire was used to collect quantitative data. Both quantitative and qualitative data were analysed. The results indicated that conflicts, inactiveness of members of the Community Based Water Supply Organisation (COBWSO) in Kibaoni village (one of three case villages), overlapping of responsibilities among key actors, as well as ineffective revenue collection were the main challenges facing water resources governance. The author concludes that concerted efforts are needed to address governance challenges hampering equitable access to water resources among different users.
