    Gas extraction operations and livelihood diversification in Tanzania: rhetoric and reality
    (Elsevier Ltd, 2023-06-20) Musoma, Beston Musa; Nyanda, Suzana Samson; Muhanga, Mikidadi Idd; Massawe, Fatihiya Ally
    The lives and livelihoods of farming and fishing communities in rural Tanzania are highly sus­ ceptible to extractive investment operations. Livelihood diversification in communities beyond agriculture and fishing can be an effective way to cope with the adverse impacts of extractive investment operations. Gas extraction operations (GEOs) are expected to change and diversify communities’ livelihoods. Tanzania has new GEOs; thus, it is necessary to investigate how they have diversified livelihoods in Mtwara Rural District. This article addresses the associations be­ tween GEOs and diversifying livelihoods. The paper explores (i) livelihood diversification before and during GEOs, (ii) associations between GEOs and villagers’ livelihoods diversification, and (iii) communities’ perspectives on GEOs and livelihood diversification. Proportionate stratified sampling was used to obtain 260 respondents. A questionnaire-based survey, four (4) Focus Group Discussions (FGDs), and fifteen (15) Key Informant Interviews (KIIs) were used to collect data. IBM-SPSS version 25 was used to analyse quantitative data. The Chi-square test was employed to analyse livelihood diversification concerning GEOs. Content analysis was used for qualitative data. Near and distant communities saw farming decline by 81.5% and 83.5%, respectively. Also, fishing declined by 85.2% and 83.7%. On the other hand, GEOs enhanced motorbike transport by 160.0% and 300.0%, food vending improved by 166.7% and 236.4%, and seashell collection increased by 816.0% and 462.5%, respectively. GEOs diversified farming (p = 0.001), fishing (p = 0.008), agricultural wage labour (p = 0.000), and crop business (p = 0.036) with moderate strength of association. GEOs have diversified livelihoods in the study area. The study demon­ strates that communities surrounding GEOs are highly socioeconomically vulnerable due to GEOs which caused declining agricultural and fish catches, thus negatively affecting their livelihoods. It is recommended that long-term programmes such as the building of diverse agro-based enter­ prises for job creation, training on income-generating occupations, agribusiness and technical training are required to increase earnings and enhance living standards. Both public and private entities should conduct a targeted and context-specific initiative to increase livelihood diversi­ fication among nearby and distant households, which can improve livelihood resilience.

    Profitability analysis of tree growing in the Southern Highlands of Tanzania
    (HINDAWI, 2021-01) Lusambo, Leopold Pascal; Nyanda, Suzana Samson; Mhando, David Gongwe
    This study aimed at determining the extent to which the smallholder tree growers benefit from tree growing activities. It strove to accomplish the following: (i) analyse costs and benefits associated with tree growing activities; (ii) determine profitability indices; and (iii) assess economic status of respondents in the study area. Stratified random sampling technique was used to draw respondents. Mixed research methods for data collection were employed: household survey using semistructured questionnaire, key informants’ interviews, focus group discussions, and researcher’s direct observation. Data were analysed using Statistical Package for Social Sciences (SPSS) and Microsoft Excel computer programmes. Profitability was analysed by gross profit margin (GPM) and return on investment (ROI). Findings suggested that tree growing activities are profitable with GPM of 21% and ROI of 26%. ANOVA results showed no statistical difference within study districts between tree growers and non-tree growers. The possible explanation of this situation could be that tree growers have not invested much the benefits they get from tree growing into asset endowment. ANOVA results on household income revealed a similar pattern except in Njombe DC where there was a statistical significant difference in household income between tree growers and non-tree growers (F (1, 64) � 5.989, P � 0.017). The effect size of the difference is medium (Eta � 0.08). It is concluded that tree growing activities in the Southern Highlands of Tanzania are economically profitable.
