The use of species–stem curves in sampling the development of the Zambian miombo woodland species in charcoal production and slash-and-burn regrowth stands
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: S Syampungani --- School of Natural Resources, Zambia CJ Geldenhuys --- Department of Forest and Wood Science, South Africa PW Chirwa --- Faculty of Natural and Agricultural Sciences, South AfricaThe use of fixed-area plot methods was considered unsuitable to compare the responses and recovery over time of different miombo woodland species to different land-use practices (i.e. charcoal production and slash-and-burn agriculture). Young regrowth stages have many stems and the... -
Thermal energy conservation strategy: A case of a modified local charcoal stove utilisation
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Alex Okibe Edeoja --- Department of Mechanical Engineering, Nigeria Andrew C. Eloka-Eboka --- Discipline of Mechanical Engineering, South AfricaThe proliferation and use of charcoal stoves is on the increase even in urban locations in Africa despite the environmental hazard associated with charcoal production. The rising cost of fossil fuel, the smokeless nature of charcoal combustion and probably inexistent... -
Development of a charcoal-fuelled dryer for the production of organic fertilizer from hog waste
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: B.O. Akinnuli --- Department of Mechanical Engineering, Nigeria O.P. Bodunde --- Department of Mechanical Engineering, NigeriaThe negligence of livestock farmers regarding waste disposal and inadequate waste control facilities are becoming a serious health and environmental hazard. In this study, a charcoal-fuelled dryer was developed to eliminate the moisture content in hog waste for easy conversion... -
Adoption of innovation technology in the face of efficient energy use: A case of improved biomass stoves in Kwara State, Nigeria
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Ibukun James Olaoye --- , Nigeria Morolake Bolaji --- , Nigeria Adeola Oreoluwa Oloyede --- , NigeriaGiven that locally developed innovation technology can foster sustainable growth and development, this study assessed the factors that underpinned the choice of improved biomass stoves among rural households in Kwara South, Nigeria. The study involved the use of primary and... -
Charcoal heaps volume estimation based on unmanned aerial vehicles
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Luiza Marina Esteves de Carvalho --- , Brazil Alessandra Melo --- , Brazil Glauco José de Matos Umbelino --- , Brazil Jan-Peter Mund --- , Germany Jhonathan Gomes dos Santos --- , Brazil Jacqueline Rosette --- , United Kingdom Daniel Silveira --- , São Paulo Eric Bastos Gorgens --- , BrazilThe charcoal stock in a forestry business is controlled based on the theoretical capacity of the masonry ovens (input) and shipped trucks (output). During the year, the company must monitor the stock for accountability reports and internal governance. This paper... -
Sedimentary charcoal studies from southern Africa’s grassy biomes: a potential resource for informing the management of fires and ecosystems
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Abraham N Dabengwa --- , South Africa Sally Archibald --- , South Africa Jemma Finch --- , South Africa Louis Scott --- , South Africa Lindsey Gillson --- , South Africa William J Bond --- , South AfricaAfrican grassy biomes evolved together with fire and have a long history of human manipulation of fire, yet few rangeland studies acknowledge the role of prehistoric fire in shaping contemporary ecological patterns. Nevertheless, prehistoric fire records have been used elsewhere... -
Contested landscapes: fragments and afterlives of the colonial rail in Tanzania
Item type: Journal Article • Journal: Anthropology Southern Africa • Authors: Samwel Moses Ntapanta --- University of Bayreuth, GermanyThis article traces the fragments and afterlife of the colonial rail as a material object in Tanzania. The rail was a tool for exploitation and proper control of the colony. The rails changed the land. The land was shaped and... -
