Effect of rooting media and indole-3-butyric acid concentrations on regeneration potential of Elgon Olive (Olea welwitschii (Knobl.) Gilg & Schellenb) stem cuttings
(Tanzania Journal of Forestry and Nature Conservation, 2017) Maduka, S. M; Msogoya, T. J; Chamshama, S. A. O
Elgon olive which is prized for durable structures and furniture has become rare and efforts to increase its population have been hampered by poor seed germination rates associated with dormancy. Search for alternative multiplication of the species is therefore important. The effect of rooting media and rooting hormone on regeneration potential of O. welwitschii were evaluated using leafy juvenile stem cuttings as an alternative multiplication method. A factorial experiment with 3 x 3 treatment combinations was established in a non-mist propagator in a complete randomized design with three replications. Factor one had three types of rooting media (fine river sand mixed with decomposed sawdust at 1:1 v/v, red clay subsoil and fine river sand) and factor two was rooting hormone indole-3- butyric acid (IBA) with three concentrations (0, 3000 and 6000 ppm). Data on rooting percentages and rooting variables were subjected to analysis of variance using SAS. The combination of fine sand mixed with decomposed sawdust media and cuttings treated with IBA at 6000 ppm provided the highest (p < 0.05) rooting of 92.3% and largest (p < 0.05) number of roots per cutting of 13.77. The combination of fine river sand mixed with decomposed sawdust and treated leafy juvenile stem cuttings with IBA at concentration of 6000 ppm is recommended as alternative technique for optimum production of O. welwitschii planting materials.
Participatory forest management for more than a decade in Tanzania: does it live up to its goals?
(Tanzania Journal of Forestry and Nature Conservation, 2013) Ngaga, Y. M; Treue, T; Meilby, H; Lund, J. F; Chamshama, S. A. O; Theilade, I; Njana, M. A; Ngowi, S. E; Mwakalukwa, E. E; Isango, J. A. K; Burgess, N. D; Kajembe, G. C
In Tanzania, Participatory Forest Management (PFM) was introduced in order to address the challenge of deforestation which continues at alarming rate. Equally, PFM aimed to involve communities adjacent to forests in management of forest resources while at the same time accrue economic benefits. PFM consists of Community Based Forest Management (CBFM) and Joint Forest Management (JFM). CBFM takes place on village land, in forests that are owned by the village while JFM takes place in Central or Local Government forest reserves (FRs) whereby owner of the FR and adjacent communities jointly manage and share benefits accrued from the FR. This study aimed to assess the role of PFM in sustainable exploitation of forest resources, equitable economic benefits and good forest governance. Generally, the study concludes that PFM can and does contribute to sustainable utilisation of forest resources and that, households across wealth categories benefit economically from PFM. However, there is a slight tendency that the rich benefit more than the poor. Similarly, the study concludes that, while CBFM and JFM have formally established appropriate institutions for PFM, this has not promoted enfranchisement and inclusiveness. The problem of elite capture in PFM should be addressed through information and education.
