Contribution of improved charcoal kilns to the households income in developing Countries: the case of Kilindi district, Tanzania
(Tanzania Journal of Forestry and Nature Conservation, 2022) Fitwangile, P.; Mombo, F; Mariki, S
About ninety percent of the country’s energy needs are satisfied through charcoal and firewood. This study was conducted to assess the contribution of improved charcoal kilns to the household income in Kilindi District, Tanzania. Simple random sampling was applied to select two wards from 21 wards, and one village from each ward. A total of 200 charcoal producers were randomly selected. The data collection tools were questionnaires and focus group discussion. The profit analysis was conducted using gross margins technique. The student t-test statistics was conducted to determine if there was statistically significant difference between the two values (improved and traditional kilns). The findings show that charcoal production activities contributed 82% of the total household income. The gross margin from using improved kilns was 52% while using traditional kilns was 26%. The t-test show that the difference in gross margin was statistically significant at p-value of 0.02 inferring that charcoal producers who used improved kilns in the study area generated more income than those who used traditional kilns. The study recommends that local governments should sensitise communities on advantages of using of improved charcoal kilns since it has shown a positive impact on the household income and reduces forest degradation.
Increased biomass for carbon stock in participatory forest managed miombo woodlands of Tanzania
(2016) Lusambo, L. P; Lupala, Z. J; Midtgaard, F; Ngaga, Y. M; Kessy, J. F; Abdallah, J. M; Kingazi, S. P; Mombo, F; Nyamoga, G. Z
Miombo (Zambezian savanna) woodlands are important forest vegetation in Tanzania. The forests contain biomass which is vital for climate change mitigation strategy. However the extent of increasing biomass under participatory forest management for carbon sequestration and storage is not clear. Understanding of this biomass will aid development of effective climate change mitigation strategies and promote sustainable forest management. This study involved 276 systematically determined concentric sample plots laid out in eight miombo woodland forests (four in Mbeya region and four in Iringa region). Of these plots, 145 were laid in participatory managed forests and 131 in reference scenario, called business as usual (BAU) or open access forest selected in proximity. The main finding was that most of PFM forests had significant increase in biomass (P < 0.05) as compared to the reference scenario. Mean biomass increased from 48.05 t/ha ± 0.03 to 37.91 t/ha ± 0.19 in PFM forests. Likewise mean biomass was 37.91 t/ha ± 0.11 to15.79 t/ha ± 0.13 for reference scenario BAU forests. This implied higher average carbon stock in participatory managed forests (21.37 t/ha) against the reference scenario (11.28 t/ha). The results provide evidence that participatory forest management approach in miombo woodlands of Tanzania have potential for climate change mitigation strategies. Despite the challenge in determining reference scenario, these findings present useful benchmark against which further study can be performed.
