    Household Welfare Improvement in The Mbulu District of Tanzania: Does Rural Electrification Matter?
    (The Royal Society of Chemistry, 2024-07-02) Matimbwa, Hadija.; Mng'ong'o, Marco E.
    Access to electricity is crucial for basic human activities and serves as a direct measure of energy poverty. In recent years, intergovernmental organizations have made significant strides in rural electrification to ensure energy security for all (rural populations, the poor, and the vulnerable). In developing countries, there is a positive correlation between rural infrastructure enhancement and rural livelihoods. Since the early 2000s, in Tanzania, there has been a major government rural electrification initiative to boost rural development. However, the extent to which rural electrification improves rural livelihoods remains unclear. This study was conducted to investigate the impact of rural electrification on household livelihoods in Tanzania, using the Mbulu District as a case study. The study employed a mixed research approach, combining qualitative and quantitative methods. The data were collected from 447 respondents through surveys and interviews with households in electrified and non-electrified areas, where information such as income levels, health, education access, self-employment, and asset ownership was collected. The results indicated a significant 45% increase in household income following electrification compared to non-electrification. About 47% of the respondents earned over 1 000 000 Tsh per month post-electrification, compared to 6% before. Access to modern healthcare improved, with 36% of the respondents being able to afford medication after electrification compared to 13% before electrification. Furthermore, educational opportunities expanded where 31% of the children were enrolled in private schools after electrification compared to 11% before electrification. Asset ownership showed marked improvements, with fewer households living in mud houses (10% post-electrification, down from 22%); all this confirms the significant impact of rural electrification on the improvement of rural development and household livelihood. Our study concludes that rural electrification significantly boosts household income, health service provision, education, and overall welfare which have a significant impact on environmental management. It recommends continued investment and sustained efforts from stakeholders, including the Tanzania Electricity Supply Company (TANESCO) to address challenges hindering electricity service expansion in rural areas. This study provides a foundation for informed policy decisions and actionable strategies to promote sustainable development in rural communities

    The Role of Conservation Agriculture in Enhancing Biodiversity and Common Beans Productivity
    (Elsevier B.V, 2026) Mng’ong’o, Marco E.; Mwaipopo, Rehema E.; Ojija, Fredrick.; Matimbwa, Hadija.
    Conservation of biodiversity in agricultural landscapes is vital for maintaining ecosystem stability and resilience. Conservation agriculture, a sustainable farming approach that involves minimum tillage and reduced use of synthetic pesticides, herbicides, and growth promoters, has gained attention as a potential strategy to enhance biodiversity and reduce production costs. This study investigated the role of conservation agriculture in enhancing biodiversity and common bean productivity in Tanzania. The study compared plots practicing conservation agriculture (minimum tillage and reduced agrochemical use) with those using conventional farming methods. Biodiversity metrics, that is, earthworm populations, bird species richness, bird nest abundance, bird species diversity, bee visitation rates, and bean yield were assessed. The results showed significant positive effects of conservation agriculture on biodiversity, emphasizing its potential role in promoting sustainable agriculture, biodiversity conservation, and household improvement due to reduced production costs and increased yield per unit area. Earthworms per meter square observed to increase from 12 in the non-conservation plots to 34 in the conservation plots, which is likely to improve nutrient cycling and productivity. Furthermore, conservation plots had a higher number of bird species flying around (36− 76) compared with 14–32 in nonconservation plots (4000 m2 ) at 50 % bean flowering. The number of bird nests observed in the two plots during bean harvesting varied significantly (P
