The contribution of Dioscorea hirtiflora to the livelihoods of local communities in Lindi and Mtwara Regions, Tanzania

This study assessed the contribution of Dioscorea hirtiflora to the livelihoods of local communities in the Lindi and Mtwara regions of Tanzania. Specifically, it aimed to identify and assess the factors influencing the utilization of D. hirtiflora (Ming'oko), examine the socioeconomic factors influencing its collection, and evaluate its contribution to rural livelihoods. The study used a sample size of 160 respondents randomly selected from eight villages: Mnamba, Madangwa, Hingawali, Nachunyu, Mkunwa, Dihimba, Namayanga, and Pachoto B. Primary data were collected using a structured questionnaire, while secondary data were obtained from District Forest and Agricultural Offices. Data analysis was performed using SPSS software, with descriptive and inferential statistics determined, and regression analysis conducted to assess relationships between variables. The findings indicate a positive relationship between the collection of D. hirtiflora and certain socioeconomic variables. The study found that tubers are harvested from the wild throughout the year, with the highest activity occurring between May and November, peaking in June. Based on these findings, the study recommends that the government and NGOs invest in the propagation and domestication of D. hirtiflora to ensure a sustainable supply throughout the year.
