Control of soil erosion in mzinga river catchment In the Uluguru Mountains, Tanzania: Approaches and practices
(Tanzania Journal for Population studies and Development, 2017) Mulengera, M. K.; Lulandala, L. L.; Maliondo, S. M; Maerere, A. P.; Temu, R. P. C.; Msuya, C. P.
Soil erosion is a serious problem in Tanzania that leads to land degradation and rapid siltation of water reservoirs and water supply structures. This paper presents findings from a project initiated in 2003/2004 to rehabilitate the Mzinga River Catchment. The objective of the project was to rehabilitate the highly degraded catchment in order to improve peoples’ economic well being by imparting knowledge of raising tree seedlings in nurseries, growing forest and fruit trees, practicing agroforestry, and by establishing mechanical conservation works. The catchment conservation approach adopted was land user free choice in collaboration with community conservation committee and other key stake holders. Soil erosion measurements were done on fields, fallow lands, and semi-natural vegetation areas to monitor land use practices that contribute greatly to catchment degradation. Sediment yield modelling was done to determine rates of sediment yields from the catchment. The study results show very high soil erosion rates (up to more than 33 tons/ha) on agricultural lands, and sediment yields from the Mzinga river catchment of about 17 tons/ha per year. The study showed that conservation activities need extension to overcome the bad historical experiences of the communities in the catchment area, and to have more farmers adopting appropriate soil conservation measures after demonstrated increased productivity and economic benefits that will be achieved through good land husbandry practices and planted forest and fruit trees.
Endemism of plants in the Uluguru Mountains, Morogoro, Tanzania
(Elsevier B.V., 2008) Temu, R. P. C.; Andrew, S. M.
A survey was conducted to determine richness of Vascular Endemic Plants of the Uluguru Mountains in Morogoro, Tanzania. Strict and near- endemic species were identified and their habits, habitats and altitudinal ranges were indicated. About 108 strict endemic plant species were identified in the Uluguru Mountains. Most of the endemic species are shrubs followed by herbs, trees and climbers, and are confined to the families Rubiaceae (38 species in 11 general), Orchidaceae (13 species in 7 general) and Balsaminaceae (11 species in 1 genus). The major habitat for endemic species is the montane rain forest on the windward side ranging between 1200 and 2450 m a.s.l. The major areas where the Uluguru endemics are concentrated are the forests of Bondwa/Lupanga followed by Lukwangule/Chenzema and then Bunduki and Mgeta. These areas are therefore the major hotspots for the endemism in the Uluguru Mountains. The information presented in this paper will contribute to the conservation and management of the biodiversity of the Uluguru Mountains.
The potential of afromontane rain forests to mitigate carbon emissions in Tanzania
(2004-07-10) Maliondo, S. M.; Msanya, B. M.; Munishi, P. K. T.; Temu, R. P. C.
One of the major ways of mitigating carbon emissions is by emission avoidance or conserving existing carbon (C) pools on the land through slowing deforestation or improved forest harvesting practices. Field measures of tree dimensions and chemical soil analysis for organic carbon were used to quantify the carbon (C) storage potential of three tropical montane rain forest ecosystems; one on the slopes of Mount Kilimanjaro and two (Usambara and Uluguru) in the Eastern Arc Mountains of Tanzania. The above ground and root carbon of trees ranged from 295±8 to 5/7 ± /7 o:'. The tree carbon storage was lowest in the Kilimanjaro forest (295±8 (SD) t h"), and highest in the Usambara forest (5/7 ± /7 (SD) t s'. The C storage in the Ulugurus was 388± /0 (SD) t «'. The soil carbon storage (/423.7 t h") in Kilimanjaro was significantly higher than that in tree biomass. On the other hand the soil carbon (4/8 ± /00 and 295 ± 53 t h") in the Usambara and Uluguru respectively) was significantly lower than the biomass carbon in both forests in the Eastern A rc forests. The potential of these ecosystems to act as carbon sink and mitigate greenhouse gas emissions is evident. This capacity for carbon storage. population pressure and the extensiveness of these forests in the region makes their conservation of global significance for carbon emission mitigation.
