Item Community participation in the renewable energy sector in Tanzania(Aalborg University Press, 2020) Bishoge, Obadia Kyetuza; Kombe, Godlisten Gladstone; Mvile, Benatus NorbertCommunity participation (CP) is emphasized in the planning and implementation of the various projects and sector. Renewable energy (RE) sector like other sectors requires community participation for its effectiveness and efficiency. This review aims at exploring the community participation in the renewable sector in Tanzania. Five themes were identified for through literature review where a Seven-Step Model for comprehensive literature review was used. These themes include (i) access to information on RE resources; (ii) community awareness of the RE technologies and related policies, laws, and regulations; (iii) RE as the source of employment opportunities; and (iv) RE as an alternative to fossil fuels and for poverty alleviation. These study revealed that despite the different efforts taken by the government and other energy stakeholders the community still lack enough information and awareness about renewable energy technologies, institutional and regulatory framework. However, the interesting issue is that renewable energy sectors play an important role in providing employment opportunities to the local communities. Moreover, the use of renewable energy has contributed to poverty alleviation. For instance, hydropower has an increase in electricity supply, solar energy has improved the local households’ standard of living, education and health services. It is recommended that the government and other energy stakeholders should cooperate to provide more information and awareness of renewable energy technologies to the community. This should be accompanied by the introduction of the national policy and law which is specifically for renewable energy to enable its development.Item Community perspectives on natural gas management in Tanzania(Sage, 2022) Bishoge, Obadia Kyetuza; Kombe, Godlisten Gladstone; Mvile, Benatus NorbertSeveral studies have discussed community participation in socio-economic projects. The studies have shown that many projects that have been initiated by either the government or private sectors have encountered resistance and reluctance from the local communities and other officials due to lack of prior and continuous involvements, poor dissemination of information on the significance of the projects, and differences in priority and interests. One of the key factors for the success and sustainability of any project is a clear understanding of the community's voluntary involvement, perspectives, and expectations of the given project. This study, therefore, aims to analyze the communities’ perspectives, expectations, and concerns related to the recent discovery and management of natural gas in Tanzania. The study adopted a questionnaire survey. Data was collected from the 115 respondents from local communities of Lindi and Mtwara regions in Tanzania. The study revealed that the communities are aware of the natural gas discoveries and policies and laws related to them. It shows that a small number of employment opportunities have been created and/or are expected to increase in the future. There should be transparency and accountability in the natural gas development, contracts, and agreements. The parliament should be the most trustworthy custodian of natural gas revenues. The study revealed that the natural gas sector would enhance the living conditions of Tanzanian households and support the attainment of the country's socio-economic development.Item Energy consumption efficiency behaviours and attitudes among the community(Aalborg University Press, 2021) Bishoge, Obadia Kyetuza; Kombe, Godlisten Gladstone; Mvile, Benatus NorbertThe rapid increase of energy consumption for socioeconomic activities has been the main source of the constant rise of greenhouse gases emission, which causes global warming and climate change effects. Several factors including knowledge, attitudes, and behaviour have been reported elsewhere to influence the energy consumption rate globally. To assess the influence of these factors, some theories, models, and approaches were reviewed to provide a theoretical and conceptual framework on the influence of human knowledge, attitudes and behaviours on energy use and saving. This study assessed some parameters including, awareness, motivation factors, moral and normative concerns, environmental norms, knowledge concerns, technology adoption concerns, and contextual factors and habits. This study conducted a comprehensive literature review followed by Seven-Step Model on studies related to this work. This review work found that behavioural change is significant to address the challenges facing humanity in utilizing natural resources including energy. Also, energy consumption efficiency needs multidisciplinary and sectoral approaches. In energy-saving, individuals need to be informed on the new technologies, energy sources, production and use.Item Geophysical analysis of the Tanga Basin, Northern Coastal Tanzania, based on gravity, aeromagnetic and 2D seismic data: implication for petroleum prospectivity(Springer, 2023) Mvile, Benatus Norbert; Kiswaka, Emily Barnabas; Osinowo, Olawale Olakunle; Nalogwa, Mussa Mathew; Mshiu, Elisante Elisaimon; Lemna, Obeid Saitabau2D satellite gravity modeling constrained by a 2D seismic profile allowed geophysical mapping of five Cretaceous–Holocene sedimentary units in the Tanga Basin. The mapping of these units was based on density differences between intervals constrained by horizons from seismic interpretation. Chronologically, these units are the Lower Cretaceous and older, Upper Cretaceous–Paleocene, Eocene–Oligocene, Miocene–Pliocene, and the Quaternary intervals. Depth estimates based on Werner solutions derived from Bouguer gravity anomaly show that these units contain thick sedimentary successions with potential source and reservoir rocks for petroleum generation and accommodation, respectively. A combination of aeromagnetic and gravity data revealed the possible presence of magmatic intrusions in the study area. Structural mapping revealed the presence of at least four sub-basins in the study area. These sub-basins are bounded by major faults and dissected by several other minor faults which reach the sea bottom. The bounding faults for these sub-basins controlled the sedimentary development of the Tanga Basin. The revealed sub-basins have several structural lows interpreted as potential areas where source rocks may be present.Item Machine learning based prospect targeting: A case of gold occurrence in central parts of Tanzania, East Africa(Elsevier, 2024) Gawusu, Sidique; Mvile, Benatus Norbert; Abu, Mahamuda; Kalimenze, John DesderiusSoil geochemical analyses from central Tanzania reveal significant gold (Au) values, highlighting the potential for further exploration in the region. This study employs ensemble machine learning models—XGBoost-RF, XGBoost-SVM, and XGBoost-ANN—to enhance predictions of Au distribution. Among these, the XGBoost-ANN model showed the highest accuracy during the training phase, achieving a Mean Absolute Percentage Error (MAPE) of 1.275, a Root Mean Square Error (RMSE) of 0.031, an R² of 0.999, and a Pearson Correlation Coefficient (PCC) of 0.999. However, its performance declined in the testing phase with a MAPE of 0.0668 and an RMSE of 0.2491, indicating reduced predictiveness on new data. Spatial analyses using Global and Local Moran's I tests revealed no significant global spatial autocorrelation but identified localized clusters of high and low Au concentrations. Specific areas showed significant spatial dependence, enhancing our understanding of the complex geospatial distribution of Au. These findings support the combined use of predictive modeling and spatial statistical methods to refine mineral exploration strategies, highlighting the value of advanced analytics in identifying promising exploration targets.Item Mining and sustainable development goals in Africa(Elsevier BV, 2024) Mvile, Benatus Norbert; Bishoge, Obadia KyetuzaEvery country seeks to assure development that satisfies the requirements of the current generation without jeopardising the ability of future generations to meet their own needs. This concept was proposed in the World Commission on Environment and Development’s report, Our Common Future as Sustainable Development (SD). All United Nations members adopted the seventeen goals in 2015 to accomplish the SD. These goals are referred to as sustainable development goals (SDGs) and include 169 targets that must be met by all countries by 2030. The mining sector is critical to achieving the SDGs. While Africa is endowed with much mineral wealth potential for achieving SDGs by 2030, most of these countries are facing the problem of the “resource curse” together with other socioeconomic, environmental, and political challenges, such as civil war and extreme poverty. This review examines pertinent past and current studies to provide an overview of the relationship between the mining sector and SDGs in Africa. Relevant data and information were collected, selected, evaluated, interpreted, and presented in themes, graphs, and tables from diverse bibliographic sources, such as the Web of Sciences, Google Scholar, and grey literature. This study revealed that mining does not involve a single primary point of interaction with a single SDG. Instead, it contributes to multiple goals at the same time. This is because mining operations and businesses have numerous beneficial and negative effects on communities, ecosystems, and economies. It contributes to eliminating extreme poverty, reducing hunger, and improving human health and education in communities. It generates foreign revenue and creates jobs, allowing governments to enhance their socioeconomic infrastructure. However, the mining industry is still overwhelmingly male-dominated, and contributes to environmental problems such as climate change and other social constraints such as political instability.Item Mining and sustainable development goals in Africa(Elsevier, 2024-03) Mvile, Benatus Norbert; Bishoge, Obadia KyetuzaEvery country seeks to assure development that satisfies the requirements of the current generation without jeopardising the ability of future generations to meet their own needs.

Although the Tanga onshore basin has the potential of adding to the hydrocarbon reserve of the country, it has very scanty literature to guide preliminary investigations into the basin prospectivity. This review seeks to highlight the petroleum system elements within the basin and how worthy it is exploring for its hydrocarbons potential. The general geology of the basin seems to have characteristics of a complete petroleum system with dolomitic limestone as source rocks and an obvious shale source rock and evidences of fossils and oil seepage around Kivundo River, although further research is needed to validate this assumption. Feldspathic sandstones are present to serve as a reservoir to economic hydrocarbon reserves. The basin has suitable thickness to provide the needed temperature and pressure for thermal maturity of any existing organic matter (OM) and to expel them from their various ‘kitchens’. Brittle structures are available to facilitate the migration of expelled kerogens. Structural straps are available via micro-folds and faults, to ensure the accumulation of economic quantities that could be explored and exploited at profit. Also, the Tanga onshore basin has geological analogies that are similar to other basins’ hydrocarbon discoveries including that in Rovuma, Morondava and Songo Songo basins which are to the south of Tanga onshore basin.Item Provenance studies of Au-bearing stream sediments and performance assessment of machine learning-based models: insight from whole-rock geochemistry central Tanzania, East Africa(Springer Science and Business Media LLC, 2024) Abu, Mahamuda; Mvile, Benatus Norbert; Kalimenze, John DesderiusThe source of clastic sediments generally, can be traced to their source through provenance studies using the whole rock geochemistry of clastic sediments. However, the provenance of the Au-bearing stream sediments within the central parts of Tanzania is yet to be deciphered. Hence, in this study, to enhance exploration targeting, the source of the Au-bearing stream sediments was characterized using whole-rock geochemistry. The performance of linear regression (LR), decision tree (DT), and polynomial regression (PR) models as prediction models for the Au mineralization in the area, were also compared as additional Au exploration techniques worth exploring in the area. The weathering condition proxies, CIA, ICV, CIW, and PIA as well as discriminant diagrams suggest weakly to intensely weathered sediments. The values of SiO2/Al2O3 and K2O/Al2O3 are indicative of felsic source rocks rather than compositional maturity due to sediments reworking. From Th/Cr, Cr/Th, Th/U, La/Sc, and Th/Sc proxies, the Au-bearing stream sediments are sourced from felsic igneous rocks. These indications are corroborated by the correlation matrix assessment. However, Au is not sourced from the same source rocks as the host sediments due probably, to a prior depositional mixing of the sediments before subsequent transportation to their current depositional environment. With R2 (0.62), MAE (0.6035), MSE (0.6546), and RMSE (0.8091) for LR, R2 (1.0), MAE (0.7500), MSE (1.6273), and RMSE (1.2752) for DT, and R2 (1.0), MAE (2.6608), MSE (12.7840), and RMSE (3.5755), for PR. The LR model performs better in predicting the Au occurrence in the area.Item Provenance studies of Au-bearing stream sediments and performance assessment of machine learning-based models: insight from whole-rock geochemistry central Tanzania, East Africa(Springer Science and Business Media LLC, 2024) Abu, Mahamuda; Mvile, Benatus Norbert; Kalimenze, John DesderiusThe source of clastic sediments generally, can be traced to their source through provenance studies using the whole rock geochemistry of clastic sediments.

When combined to production well data, high quality 4D seismic is very useful to address production changes in a reservoir over time. This becomes very challenging though, for most of the clastic reservoirs from the J-Area field, in Central North Sea. These reservoirs are frequently compartmentalized with complex faulting which can result in different initial fluid contacts and pressures across the same field. Full understanding of which faults are acting as hydrocarbon baffles or flow barriers would be very useful in optimizing drilling. This work aimed to determine whether 4D seismic techniques could realistically aid this understanding by quantifying the reservoir production effects relating to pore pressure and water saturation changes in J-Area Triassic using real and predicted well data. It further aimed at testing the viability of repeated seismic reservoir monitoring in this field using the normalized root mean square (NRMS) technique. The modelled 4D seismic response derived from synthetic seismic traces based on seismic volumes generated from the well data was used to design a new dedicated 4D survey. The results show that both pore pressure depletion and water saturation changes produce a significant 4D effects in the reservoir. Yet, pore pressure depletion become the major production effect in this field as the majority of 4D effects are due to pore pressure reduction through depletion of the reservoir. The study suggest that, for optimum reservoir monitoring, a baseline survey must be reprocessed in parallel with the monitor survey to reduce the NRMS noise or alternatively a dedicated repeat survey is acquired matching the design of the latest vintage of seismic.Item The “resource curse” from the oil and natural gas sector: How can Tanzania avoid it in reality?(Springer, 2020) Mvile, Benatus Norbert; Bishoge, Obadia KyetuzaThe discovery of a lot of natural resources such as petroleum, natural gas, and minerals has become the source of poverty, deprivation, and inequality in some countries. The failure to properly use those resources has been associated with the “resource curse” or “paradox of plenty” concept. This happens when the resource-rich countries fail to benefit fully from their natural resources’ wealth, something that leads to the failure of the governments of the relevant countries to respond effectively and efficiently to public welfare requirements. In recent years, Tanzania has discovered a lot of oil and gas resources which are expected to contribute more to the sustainable development of the country. However, the question here is whether Tanzania will not face the challenge of resource curse as it has been observed in other developing countries that are rich in natural resources. Thus, this paper is intended to analyze the relationship between the resource curse, natural resources, and economy. It examines the resource curse in some contracting countries such as Zambia, Nigeria, and Gabon. It furthermore pinpoints on how Tanzania can avoid the resource curse.Item Soil geochemistry and multivariate statistical assessment of Copper–Gold-PGEs mineralization in parts of Singida Region of the Tanzania Craton, Tanzania, East Africa(Springer, 2023) Kalimenze, John Desderius; Abu, Mahamuda; Mvile, Benatus NorbertMulti-element mineralization of copper (Cu), gold (Au), and precious group of elements (PGEs) in the Kishapu-Igunga-Iramba areas in the central parts of Tanzania was evaluated in the study. The main aim was to characterize the mineralization with a focus on the pathfinder elements and the controls of the mineralization in the area through soil geochemistry and multivariate statistics and multivariate linear regression (MLR) methods. From the multivariate statistical methods applied, the Cu, Au, and PGEs mineralization in the area is associated with arsenic (As) and antimony (Sb). The Cu and Au occurrence in the area is a likely porphyry Cu-Au from their strong association. The mineralization (multi-elements) is strongly controlled by mafic–ultramafic rocks and volcaniclastics in the northern, southern, and central parts of the study area. From the MLR, Cu is strongly predicted by Zn, Ni, and Au with an error of ± 0.230, with Pd being predicted by only Pt and vice versa, with an error margin of ± 0.001. Au on the other hand is predicted by Cu, Fe, and Cr with an error margin of ± 0.473. The style of mineralization of these elements is comparable to their occurrence in the Neoproterozoic setting and the Paleoproterozoic Ubendian belt of Tanzania as well as the PGEs occurrence in South Africa and Canada. Coupling MLR with hierarchical cluster analysis and factor analysis brings out a more definitive elemental association to precious minerals occurrence from the study and is strongly recommendedItem Sources and pollution assessment of trace elements in soils of the central, Dodoma region, East Africa: implication for public health monitoring(Elsevier, 2021) Abu, Mahamuda; Kalimenze, John; Mvile, Benatus Norbert; Kazapoe, Raymond WebrahThe study assesses the pollution levels and sources in soils of As, Pb, Cu, Zn, Cd, Mn, Cr, Co, Ni and Se in the central Dodoma region of Tanzania from estimations of CF, EF, Igeo, PLI and RI together with PCA, FA and HCA multivariate techniques. Generally, the capital city’s regional area is polluted with these heavy metals with PLI > 1 and EFs > 40. The Igeo also shows concerning concentration levels of As with 60.77 % of the study area being moderately to extremely polluted by As and As, Cd and Pb are the heavy metals that requires immediate monitoring within the Dodoma region. The multivariate analysis supports a dominant geogenic source of these heavy metals with the mafic ore bearing lithology controlling these elemental concentrations in soils via chemical weathering of pyrites, arsenopyrite and chalcopyrite as the most probable geological process releasing these heavy metals into the soil. The fast growing industrialization of the region with its associated commercial agriculture activities, also contributes although it may be small for now, to the heavy metals contents in soils within the area. With the pace of industrialization coupled with the desire of the country to create jobs through small scale activities, it is appropriate and timely to assess the levels of As, Cd and Pb in surface and groundwater as well as in some cereals like maize or millet which are the main stay of the people, and should be centered at the northern and central parts of the region. This is necessary for effective public health monitoring and to enhance environmental management practices in the region.Item Stimulated Raman side and backscatter instabilities of crossed laser beams in plasma(Elsevier BV, 2023) Singh, Vijay; Mvile, Benatus Norbert; Pandey, Anoop KumarStimulated Raman scattering (SRS) instability due to two nonlinearly coupled laser beams propagating in homogeneous, thermal plasma is analyzed. The temporal evolution equations for pump, scattered and Langmuir waves excited due to the interaction are set up. Using numerical techniques temporal evolution of amplitudes of pump, scattered and resultant Langmuir waves for side and back SRS instabilities have been obtained in the non-relativistic regime. The temporal growth rate, saturation time and saturation amplitude of waves excited by two crossed (perpendicular) lasers are studied and compared with the single beam case. The model considers pump depletion to be the dominant saturation mechanism. The study points towards a new concept for generation of high amplitude Langmuir waves.Item The search for plausible economic mineral deposits in the central parts of Tanzania; insight from stream sediment geochemistry, multivariate statistics and geostatistics(Elsevier BV, 2023) Nunoo, Samuel; Mvile, Benatus Norbert; Abu, Mahamuda; Kelimenze, John DesderiusExploration success relies heavily on the data obtained, but, significantly on the type of analytical methods deployed and the interpretation reached. A poorly analyzed data may obscure the true reflectivity of the data, and thus, compromised the decision made. A combined data processing approach of descriptive statistics, enrichment-depletion data normalization, geospatial elemental distribution, and stacked overlayed comparison of elements have been used in this study. The prime purpose was to demonstrate potential elemental anomalies, and predict areas of higher degree of confidence for subsequent exploration and mineral resource evaluation. One-hundred and sixty-six stream sediment samples from the Dodoma Region of the Tanzania Craton have been examined; to reveal potential elements or mineral commodity that warrant further exploration. Forty-three elements of target were examined, as this craton is globally known for its rich earth mineral commodity. Our result indicates an enrichment of transition metals (TMs) (Cu, Ni, Co, Cr, Mn and Zn), High Field Strength Elements (Y, Th, U, Zr, Nb, Hf, Ta and Pb), Large Ion Lithophile Elements (Ba and Rb) and Rare-Earth Elements (La and Ce), Platinum Group Element (Pd and Pt) and other metals (Au, As, Bi, W, Mo and Li). Obtained results point to a likely poly-metallic sources and processes; as the underlain geology is marked largely by pegmatite and migmatites, and moderate proportion of fine clastic sedimentary rocks, and minor volcanic rocks mostly to the northern domain. Theoretically, the Large Ion Lithophile Elements (LILEs), Rare-Earth Elements (REEs) and Platinum Group Elements (PGEs) are associated with felsic rocks or variable stages of plutonic granitization. Although, the TMs are often associated with mafic-ultramafic rocks, the linkage of such metals with organic-rich shales been reported elsewhere. These rocks may equally contribute to the occurrence of other metals as stated in this paper. Its intriguing to note a strong positive correlation of Li with TMs, possibility of Li control by mafic minerals in pegmatite bodies. This work proposes a polymetallic enrichment controlled by the area geology. To suggest an alluvial mining potential of the above elements in the area, resource evaluation is a requirement. The geospatial maps reveal areas worth focusing for subsequent exploration. The adopted geostatistical methods and other approach utilized in this research are effective, indicative of handling bulk exploration data for decision and subsequent exploration.
