    Local Institutions and the Governance of Tree Resources: The Case of the Shea Tree (Vitellaria paradoxa C.F Gaertn.) in West Nile Region of Uganda
    (Conservation & Society, 2021) Acema, Dan; Byakagaba, Patrick; Banana, Abwoli Y.; Turyahabwe, Nelson
    The role of institutions in conservation of biological resources is globally recognised. This study is aimed at assessing institutions governing conservation and management of the Shea tree in West-Nile region of Uganda where it is at risk of extirpation. Arua and Nebbi districts which are dominated by different ethnic groups were selected for the study. The study involved 200 respondents, six focus groups and 20 key informants. Chi-square tests were used to analyse the origin and level of compliance to institutions between the two districts. A multinomial logit model was used to analyse factors influencing levels of rule enforcement. Content analysis was used to analyse data from key informants and focus group discussions. The results showed the existence of seven different rules that were categorised as management, conservation and harvesting rules. The level of compliance to rules for the Shea tree was higher in Nebbi than Arua. Involvement in rule crafting, clarity of resource boundary, age, education level and ethnicity of respondents significantly influenced participation in rule enforcement. The study concluded that traditional institutions are relevant in the conservation of Shea trees. It is therefore, vital to incorporate them into statutory laws in the quest for sustainable management of Shea tree.

    Physico-chemical and mechanical characterisation of the bark of selected Ficus species growing in Uganda
    (European Journal of Wood and Wood Products, 2016) Mwanja, Christine; Mugabi, Paul; Banana, Abwoli Y.
    In this study, the physical, chemical and mechanical properties of three Ficus species growing in Uganda were determined. Basic density and water absorption rate were (0.33 g/cm3, 134) in Ficus natalensis, (0.32 g/cm3, 137) in Ficus thonningii and (0.28 g/cm3, 145) in Ficus glumosa, respectively. Lignin content and tensile strength were highest in the bark of F. natalensis, and lowest in F. glumosa while cellulose content was highest in the bark of F. glumosa and lowest in F. natalensis. Based on the results, the bark is not suitable for use in industries such as paper manufacturing, where lignin is undesirable, but it can be used in manufacture of dyes and adhesives.

    Relative efficiency of sawmill types operating in Uganda's softwood plantations
    (Uganda Journal of Agricultural Sciences, 2005) Kambugu, Robert K.; Banana, Abwoli Y.; Zziwa, Ahamada; Agea, Jacob G.; Kaboggoza, John R. S.
    The overall aim of this study was to determine the appropriate saw milling technologies that should be promoted for use in Uganda's softwood plantation. Conversion efficiency, sawing accuracy, and sawing capability of four sawmill categories were evaluated. Data were collected from sawing of 604 good Aquality logs using eleven Rolling ATable Sawmills, Dimensional Swivel Sawmills, Band Sawmills, and Locally Afabricated Snwmills. Sawing accuracy data were collected from 165 boards in three timber sizes (75 mm x 50 mm, 100 mm x 50 mm, 150 mm x SO mm). Sawing capability was assessed from saw blade parameters, merchantable timber size, and size of available logs. AN OVA was used to show differences in recovery and sawing accuracy between and within sawmills. Band sawmills exhibited the most efficient sawmill technology for converting logs into sawn timber while rolling-table sawmills were more efficient than dimensional swivel and locally manufactured sawmills. Band sawmills were more accurate than sawmills in the other categories. Therefore, band sawmills should be promoted in Uganda and mechanical modifications carried out on the swivel and locally-manufactured sawmills operating in softwood plantations to improve their feed A work and setwork mechanisms
