Adefemia.jpg

Adefemi A. Alade

Femi, as he is popularly called, hails from Ekiti State in Southwest Nigeria and is studying for a PhD in Wood Product Science. His research is focusing on formulation of effective natural product-based preservative from bio-wastes for wood protection. This is aimed at reducing health and environmental impacts associated with hazardous chemical wood preservatives. He is seeking to improve, through synergy and modification, the wood preserving potentials of lignin and extract from citrus fruit peel which are industrially generated as unwanted materials in the pulping process of paper making and fruit juice processing respectively.

Werner Mbongo

Werner is a Namibian citizen and has a first degree in Forestry from the University of Namibia. Werner obtained a Master's degree (MSc.) in Forest Ecology and Management from Freiburg University, Germany (2006-2008).

Werner has worked for and with the Namibian Directorate of Forestry since 2001, among others, facilitating and supporting the establishment of community forests. Werner has also worked with the German International Development Agency (GIZ) as a Forest Expertise Resource Person, Researcher and Technical Expert, in the projects: 1) Biodiversity and Sustainable Land Management and 2) Integrated Water Resources Management, of the in collaboration with the Namibian Ministries of Environment & Tourism; and Agriculture, Water & Forestry (2007-2010). Werner has been working as a Research Assistant at the Southern Swedish Forest Research Centre of the Swedish University of Agricultural Sciences, Sweden, since 2011.

Werner's PhD project focuses on improved understanding of growth dynamics of the Zambezian-Baikiaea woodlands, with particular focus on Burkea africana and Pterocarpus angolensis. The aim is to study growth increments and regeneration responses of Zambezian-Baikiaea woodlands to silvicultural interventions, mainly thinning, through field experiments established in Namibia at Kanovlei and Hamoye State Forests and Okongo Community Forest. The project strives to understand how forest stand growth and regeneration in the Zambezian-Baikiaea woodlands vary by stand densities along thinning intensity gradients. Werner's PhD project receives partial financing from SASSCAL through the Department of Forest and Wood Science, Stellenbosch University.

SinzanoNjameli.jpg

Sinazo Njamela 

Sinazo was born and bred in a small town of Eastern Cape called Middledrift.  She has a BSc and BSc Honours in Chemistry from Fort Hare University. She obtained her MSc in Wood Product Science from Stellenbosch University. She is currently working for Sappi based at Sappi Saiccor – Umkomaas doing her PhD studies part-time. The study focuses on improving the current reactivity test methods. The study will therefore provide novelty of why the reactivity test methods give differences on various dissolving pulps. This will also assist in determining the correlation between the quick reactivity test methods, the standard viscose reactivity assessment and the dissolving pulps.

OlafOlaywola.jpg

Olayiwola Hamed Olafiku

Olayiwola Hamed Olafiku is from the largest city in West Africa, Ibadan, Nigeria. He had his B.Sc and M.Sc degrees in Wood Products Engineering from the premier university in Nigeria, University of Ibadan. His quest for finding alternative green materials to the conventional building materials led him to the Ph.D degree programme of the prestigious Stellenbosch University in Wood Product Science. The use of the conventional construction materials are highly energy intensive and processes involved in their manufacture lead to emission of greenhouse gases (GHGs) that add to the global carbon footprint. His research focuses on the development of low cost building materials by incorporating wood fibres (from alien invasive wood species) and agricultural crop residues into geopolymeric matrices developed from various industrial wastes.

Amani is a Tanzanian researcher with a BSc and MSc in Natural Resources Assessment and Management from the University of Dar es Salaam. His research focuses on the linkage between village participatory land-use planning, forest management and conservation measure under "Reduced Emission from Deforestation and Forest Degradation" (REDD+). This research will contribute to the better understanding of how community perceptions and participation can be harnessed to ensure the sustainability of the REDD+ initiatives and associated non-carbon benefits in the Kilosa District of Tanzania.

MSc

SizweGonya.jpg

Nkosinamandla Artwel Sizwe Gonya 

Nkosinamandla is from Kwa-Zulu Natal (Estcourt).  He obtained a BSc degree in Wood and Wood Products Science in 2016 at Stellenbosch University, currently doing MSc in the same field.

Topic of Research: Profiling the shrinkage and collapse of Eucalptus grandis across the tree trunk and height-wise, and their relationship to the basic tree and wood properties.

We hope to solve the shrinkage and collapse (dimensional instability) experienced in Eucalyptus grandis after drying by grouping boards from parts with more similar properties in the tree stem, hence being able to use this fast growing wood for structural purposes.

Rugare.jpg

Custon Rugare

Custon is from Buhera District in Zimbabwe and currently doing MSc in Forest Engineering.

The number of mechanised CTL harvesting operations are rapidly increasing in South Africa.  Being a relatively new phenomena and a significant departure from motor-manual operations of the past it is important to understand the contribution of machine costs and productivity to the overall success of mechanisation initiatives.  Ratio's such as availability and utilisation are largely unknown or a best poorly understood.  The same applies to repair and maintenance costs along with the costs of running gear.  This research uses long term operational records and machine computer systems to provide base information for the calculation of benchmark information which machine owners can use to potentially validate their data being use in day to day operations.
