Thesis (MScFor)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: Wood scarcity remains the main challenge for many rural households who still rely on natural resources for energy needs. This study aimed to investigate the relationship between fuel use and quality and quantity of fuel in two rural villages (Ongulumbashe and Onaitembu) in the Omusati Region of Namibia. It investigated the impact of fuel quality and quantity and the corresponding sales of firewood on households’ energy consumption. Data was collected between April and June 2012 from the two villages by means of questionnaire surveys, biomass assessment and laboratory assessment. Interviews were conducted with seventy-seven households, four firewood sellers, government officials, and local leaders. The study quantified the amount of fuelwood consumed and collected per household per week using user-recall and physical measurement, respectively. The most preferred fuel species or fuel materials were identified and their physical properties, calorific value, moisture content, ash content and density were measured under laboratory conditions. Differences between the two villages in terms of fuelwood collected and consumed were found. Due to wood scarcity households from Onaitembu village used other alternatives (buying fuelwood and cutting live firewood) rather than collecting dead firewood. The study found a link between fuelwood use, quality and quantity, with households changing their consumption and harvesting based on season, fuelwood demand and availability of fuelwood. The average weekly fuelwood consumption per household ranged from 66 kg to 79 kg for a firewood abundant area and from 59 kg to 67 kg for an area with a shortage of firewood. Mopane was the most preferred species due to its ability to burn efficiently and its abundance. Wood scarcity affected households economically, culturally and nutritionally. The study found that households in degraded areas spend an average of N$ 50 per week on fuelwood, and many households depended on government grants and small cash income activities. The study found that the government, through the Ministry of Agriculture, Water and Forestry, is trying to improve rural households’ energy use by constructing firewood outlets. The study concluded that there is a high level of illegal trade in firewood that will require government to increase the number of staff in the region as well as to strengthen its policy on cross-border trading. There is an imbalance in fuel species use in areas of rich biomass and over-utilization of resources in degraded areas. These require the Directorate of Forestry to educate the community about the value of other possible fuel species and the impact of harvesting live firewood on households’ livelihood and on the environment. / AFRIKAANSE OPSOMMING: Houtskaarsheid bly die grootste uitdaging vir baie landelike huishoudings, wat nog steeds staatmaak op natuurlike hulpbronne vir energie behoeftes. Hierdie studie het gepoog om die verhouding tussen brandstof gebruik en kwaliteit en kwantiteit van brandstof in twee plattelandse dorpies (Ongulumbashe en Onaitembu) in die Omusati-streek van Namibië te ondersoek. Die impak van brandstof kwaliteit en kwantiteit en verkope van brandhout op huishoudings se energie gebruik is ondersoek. Data is ingesamel in April en Junie 2012 in die twee dorpe deur middel van vraelys opnames, biomassa assessering en laboratorium ontledings. Onderhoude is gevoer met 77 huishoudings, vier brandhoutverkopers, regeringsamptenare, en plaaslike leiers. Die studie het die hoeveelheid vuurmaakhout verbruik en versamel per huishouding per week gekwantifiseer deur gebruik te maak van gebruikergeheue en fisiese meting van vuurmaakhout. Die mees gewilde brandstof spesies of brandstof materiaal is geïdentifiseer en hul fisiese eienskappe, kaloriewaarde, voginhoud, asinhoud en digtheid is onder laboratorium toestand gemeet. Verskille tussen die twee dorpe in terme van brandhout versamel en verbruik is gevind. As gevolg van houtskaarsheid gebruik huishoudings in ONA ander alternatiewe energiebronne, soos om brandhout te koop of om vars hout te saag, in plaas van om dooie hout te versamel. Die studie het ‘n skakel gevind tussen brandhout gebruik en die gehalte en hoeveelheid wat beskikbaar is. Huishoudings het hulle brandhout verbruik aangepas by die seisoen, aanvraag en beskikbaarheid van brandhout. Die gemiddelde weeklikse brandhout verbruik per huishouding het gewissel tussen 66 kg tot 79 kg vir 'n area met ‘n oorvloed van brandhout en 59 kg tot 67 kg vir 'n gebied met 'n tekort aan brandhout. Mopanie was die mees gewilde spesie as gevolg van sy besikibaarheid en vermoë om doeltreffendheid te brand. Houtskaarstes beinvloed huishoudings op ekonomies, kulturele en voedings vlakk. De studie het bevind dat huishoudings in ’n area met ‘n houtskaarste gemiddeld N$50 per week spandeer om brandhout te koop en dat baie huishoudings afhanklik is van staatstoelaes en klein kontant inkomste-aktiwiteite. Die studie het gevind dat die regering, deur middel van die Ministerie van Landbou, Water en Bosbou, probeer om landelike huishoudings se energie gebruik te verbeter deur die bou van brandhout afsetpunte. Die studie het tot die gevolgtrekking gekom dat daar 'n hoë vlak van onwettige handel in brandhout is wat sal vereis dat die regering die aantal amptenare in die streek moet vermeerder en sy beleid rakende handel oor landsgrense heen moet verbeter. Daar is 'n wanbalans in die gebruik van brandstofspesies in 'n gebied met baie biomassa, en oorbenutting van hulpbronne in gedegradeerde gebiede. Die Direktoraat van Bosbou moet die gemeenskape oplei oor die waarde van ander moontlike brandstofspesies en die impak van die oes van lewendige bome op huishoudings se lewensbestaan en op die omgewing.

The people of Pikoli in the Peddie district of the Eastern Cape are mostly unemployed and earn most of their income from old-age allowances. The place is remote and 'modern' amenities such as paraffin and petroleum gas are expensive. Electricity and transport are unavailable. There is heavy reliance on woody plants for fuel and for materials for construction and fencing and to some extent medicinal and ritual uses. Indigenous trees in this rural area are threatened by over-utilisation and the absence of clear government management policies. The over-utilisation of these resources is leading to deforestation. It was proposed at the beginning of this study that people who harvest trees cause similar results to the piosphere effect caused by the herbivores on the rangeland. Ecological-economic analysis was performed to find a common ground between the people's income and needs so that effective sustainable management strategies can be developed. A combination of semi-structured interviews, direct observations and ecological surveys were used to gather information about: Tree species used, and for what purpose in Pikoli; Individual tree species preference by inhabitants; Change in tree density in response to changes in utilisation intensity at varying distances away from the village; The local direct use benefits inhabitants derive from utilising indigenous tree resources. The study showed that the people of Pikoli use a variety of 23 indigenous trees and that they have marked preferences regarding the tree species they use for fuelwood and construction purposes. Although Ptaeroxylon obliquum is a highly preferred species for fuelwood and construction, its popularity can also be linked to its high relative abundance in this area. Other species such Maytenus undata and Pappea capensis are also highly preferred although they are harvested at much greater distances from thecentre of the village. Change in individual tree density in response to changes in utilisation intensity at varying distances away from the village showed clearly that a piosphere effect also applies to human harvesting. The average number of individual trees closer (1 200 m) to the village centre was 2 trees per 100 m², and their numbers increase to approximately 35 trees per 100 m² at a distance of about 3 000 m from the village centre. The study reports on the direct use benefits derived by the people of Pikoli from harvesting tree resources. The average total net value of trees harvested for fuelwood was R4089.09 (US$ 359.01) per household per annum. The value of tree resources harvested represents a large percentage of average households' annual income. Therefore, the economic benefits households derive from utilising tree resources are high. Indigenous tree resource use in this rural village seems to be unsustainable and the inhabitants seem to be aware of it. However, they have few alternatives. Their economic conditions do not allow them to afford alternative resources available in the formal market.

Thesis (MFor)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: The reliance of firewood demand on indigenous trees such as Acacia erioloba is a continuing phenomena despite the concern that over-exploitation of these resources will degrade the environment. This study tested the hypothesis that the cutting of A. erioloba in the Northern Cape is driven by (a) market demand in the Western Cape, (b) ignorance of the long-term ecological consequences and/or (c) ignorance of legislation along the chain of custody of this product. The assumption is that whoever is involved in the A. erioloba firewood industry (resource owner, trader or user) is neither aware of the protected status of the resource nor the negative consequences associated with the over-exploitation of the resource or they are driven by short term monetary gains. Therefore, there is a need to understand the needs of every participant in the chain and to further find out if there may be substitutes for A. erioloba firewood. The results of this study show that there is a market for firewood in the study area and that this demand is driven mainly by the availability rather than the quality of firewood. It will also be shown that Acacia mearnsii which is available in the study area is a better product than A. erioloba and therefore it can be a suitable replacement but consumers were found to bum almost everything that would give them embers. The most preferred firewood in the study area is A. cyclops. The concept of indigenous trees is not clearly understood by retailers and consumers. The major role players in the supply chain were found to be the retailers and the transport owners who may be targeted when firewood trade is to be stopped in the short-term. The results further highlighted the fact that the majority of consumers were aware that indigenous trees were protected in South Africa but the majority of retailers were not aware. The study recommends that firewood trade should be stopped completely by strict enforcement of the law or by the involvement of every role-player and/or that the trade should be regulated. / AFRIKAANSE OPSOMMING: Die fenomeen dat die aanvraag vir vuurmaakhout staatmaak op inheemse bome soos Acacia erioloba duur steeds voort ten spyte van die kommer dat oorbenutting van hierdie hulpbronne, ter versadiging van die behoeftes van 'n steeds toenemende populasie, die omgewing sal degradeer. Hierdie studie het die hipotese getoets dat die afsny van A. erioloba in die Noord- Kaap aangedryf word deur (a) die mark aanvraag in die Wes-Kaap, (b) onkunde oor die langtermyn ekologiese gevolge en/of (c) onkunde oor die wetgewing van hierdie produk by die skakels in die verskaffersketting. Die aanname is dat wie ook al betrokke is by die A. erioloba vuurmaakhout-industrie (hulpbron eienaar, handelaar of gebruiker) is beide onbewus van die beskermde status van die hulpbron asook van die negatiewe gevolge geassosieer met die oorbenutting van die hulpbron of hulle is aangedryf deur korttermyn monetêre gewin. Daarom is dit nodig om die behoefte van elke deelnemer in die ketting te verstaan en om verder uit te vind of daar plaasvervangers vir A. erioloba vuurmaakhout is. Die resultate van hierdie studie toon dat daar 'n aanvraag is vir vuurmaakhout in die studie-area en dat hierdie aanvraag hoofsaaklik gedryf word deur die beskikbaarheid, eerder as die kwaliteit van die hout. Daar salook aangetoon word dat Acacia mearnsii, wat in die studie-area beskikbaar is, 'n beter produk is as A. erioloba en dus 'n geskikte plaasvervanger kan wees, maar dit wil voorkom of die verbruikers omtrent enigiets sal brand wat kole sal verskaf. A. cyclops is die vuurmaakhout van voorkeur in die studie-area. Handelaars en verbruikers verstaan nie die konsep van inheemse bome duidelik nie. Die vernaamste rolspelers in die verskaffersketting is die handelaars en die eienaars van die vervoer en hulle kan die teikengroep wees as die handel in vuurmaakhout in die korttermyn stopgesit word. Die resultate het verder na vore gebring dat die meerderheid verbruikers daarvan bewus is dat inheemse bome beskermd is in Suid-Afrika, maar die meerderheid handelaars is nie hiervan bewus me. Hierdie studie maak die aanbeveling dat handel in vuurmaakhout totaal gestaak moet word deur strenger wette of deur die betrokkenheid van elke rolspeler en/of dat handel gereguleer moet word.

Forest and woodland ecosystems provide a variety of natural resources such as fuelwood, brushwood and kraal posts to local communities, as well as possess important cultural and spiritual value. However, many forests and woodlands worldwide have been unsustainably used and managed. Thus, under pressure from the international conservation community to recognise the importance of people's relationships with their surrounding natural environment, particularly for the natural resources it can provide, and given a move away from the management of forests and woodlands for sustained yields, and according to simple cause and effect models, in favour of systems approaches, South Africa has developed some of the most progressive natural resource management policies in the world. Nevertheless, for these policies to be sensitive to local contexts, there remains a need for a better understanding of how local people in different contexts, determine forest and woodland ecosystems to be of use to them, and what 'usefulness' means to different groups of resources users. This is a case study, which examines the role of fuelwood, brushwood and kraal posts in the rural livelihoods of the people of Machibi village, located in the Eastern Cape province of South Africa, through people's preferences for particular landscapes and species, accessed for these purposes, and the trade-offs people make between resource availability and resource accessibility. Key objectives of the study are to 1) determine the preferred landscapes and species for fuelwood, brushwood and kraal posts at Machibi, 2) determine the landscapes and species actually used for fuelwood, brushwood and kraal posts, and 3) with the help of a conceptual model, and using iterative modelling as a tool, determine the factors that influence people's harvesting strategies in terms of the costs and benefits associated with the different landscape and species options. On the basis of this knowledge, the study provides some guiding principles for the better use and management of these landscapes and species for fuelwood, brushwood and kraal posts. An innovative research approach and methodology that integrates social and ecological systems, works across disciplines, and draws on different types of knowledge is used to develop and test a conceptual model of the harvesting strategies of fuelwood and kraalwood users at Machibi. Participatory methods such as workshops, participatory resource mapping, ranking exercises and trend-lines were used to tap into local knowledge while plotless vegetation sampling and GIS maps were used to capture the scientific information. Results showed that people did not always use the landscapes and species they preferred. However, the local people did behave in a rational manner by weighing up the returns from harvesting and accessibility costs associated with the respective options available to them, before selecting the option(s) associated with the greatest net benefits. At the landscape level, people made trade-offs between the returns from harvesting and the accessibility costs of using particular landscapes in addition to costs associated with the physical work of harvesting fuelwood, brushwood or kraal posts from these landscapes. At the species level, people made trade-offs between the returns from harvesting and the accessibility costs of harvesting particular species for fuelwood, brushwood and kraal posts, or the costs of commercial alternatives. Costbenefit factors that influenced people's resource use patterns also differed across landscapes and species for fuelwood, brushwood and kraal posts, respectively. Consequently, a range of diverse and flexible management options and strategies is recommended for the wise use and management of these landscapes and species, focused on short, medium and long term goals. These strategies examine the use of cost - benefit incentives to influence people’s landscape and species use patterns.

Text in English with summaries and keywords in English, Venda and Sepedi / Fuelwood remains a crucial source of energy among the vast majority of rural households because of its availability and affordability in comparison with most energy alternatives. Approximately 17 million people in South Africa live in communal lands where fuelwood can be harvested easily and freely by households, with 80% of the overall fuel consumed for domestic purposes extracted from burning fuelwood. The rapid-excess trends of fuelwood consumption – aggravated by population growth, agricultural and household settlement expansions – pose utmost challenges for community development. Overharvesting of fuelwood can result in fuelwood scarcity, loss of biodiversity, excessive land clearance and soil erosion. This study evaluated the factors that influence fuelwood consumption in households at the Thulamela Local Municipality. The study utilised mixed research methods, comprising quantitative and qualitative methods. A semi-structured questionnaire consisting of both closed and open-ended questions was used to collect data from the households. The collected data was mainly qualitative data (nominal and categorical data) and the researcher used the frequency menu to summarise the data and cross tabulation menu in the Statistical Package for Social Scientists (SPSS) version 25. For cross tabulation, the researcher used the Chi-square (χ2) test to measure the degree of association between two categorical variables. If the p-value is less than 0.05, there is a significant association between variables – thus, the variables dependent on each other. The study found that socio-economic characteristics such as monthly income, employment status, gender, educational level of the household head, number of employed household members, energy expenditure and type of occupation play a significant role in the factors that influence fuelwood consumption. As a result of these factors, fuelwood energy is still being used as a primary energy source by most households to meet their domestic needs for cooking and water heating – despite most of them being electrified. Additionally, lack of environmental education, the erratic electricity supply and staggering living conditions which drive widespread poverty in rural areas contribute to the extensive fuelwood consumption among households. The study highlighted the recommendations on mitigation measures that can be used to reduce extensive fuelwood consumption. These recommendations include encouraging the use of renewable energy and modern energy technologies such as biogas and solar energy, together with improved cooking stoves to help reduce overexploitation of natural resources and prevent indoor air pollution which is associated with heart disease and immortality. There is also a need to raise environmental awareness. It is through education that people’s perceptions, attitudes and behaviour regarding fuelwood consumption practices can be changed. The promotion of sustainable development through harvest control and afforestation can significantly reduce deforestation, loss of biodiversity, fuelwood scarcity and soil erosion. / Khuni dzi kha ḓi shumiswa sa tshiko tshihulwane tsha mafulufulu kha miṱa minzhi ya mahayani ngauri dzi a wanala na u swikelelea musi dzi tshi vhambedzwa na dziṅwe nḓila dza mafulufulu.
