Dissertations / Theses on the topic 'Rural-based livelihoods'

Small-scale forest-based enterprises (SSFBEs) are enterprises that utilize any material or product that is derived from forests, woodlands, or trees outside of forests and woodlands for income generation. Characteristically, they are small, rural, household-based operations that are technologically simple, requiring limited skills and little capital investment. Little attention has been paid to the importance of these enterprises in supporting rural livelihood in developing countries. At the same time, the income earned from SSFBEs provides an incentive for forest dwellers to manage their resources at a sustainable level, as well as helping to alleviate rural poverty. SSFBEs are, however, not without their problems. They face unstable markets, lack of raw materials, few financial resources, poor market access, and constraints on forest use and control, to name a few. The purpose of this paper is to provide a qualitative overview of SSFBEs by discussing their role in and importance to rural communities in developing countries, their significance in poverty alleviation and forest conservation, problems they face, and possible solutions.

The problem that is researched in this study relates to the effectiveness of the extension model applied in the High Value Crop programme in improving rural livelihoods in the Eastern Cape. The extent of poverty in rural areas in the Eastern Cape motivated for the intervention of the Is‘Baya through the introduction of Integrated Village Renewal Programme (IVRP). The need to improve the quality of life of rural households through the promotion of agriculture and industry gave rise to the collaborative effort between the Is‘Baya Development Trust and Agricultural Research Council (ARC) in South Africa. The HVC programme was established to mitigate the effects of food shortage and poverty through the production of fruit trees, herbs and vegetables at household level. Evaluation of the effectiveness of this collaborative effort was carried out in four local municipalities of the OR Tambo District and these included: King Sabata Dalindyebo municipality (Zangci); Nyadeni municipality (Hluleka); Port St Johns municipality (Noqhekwana) and Ngquza Hill municipality (Hombe). An equal number of villages where Siyazondla was implemented by DRDAR were visited for the survey to relate the extension model applied with HVC. The villages visited included: OR Tambo (Mhlontlo local municipality) Xhokonxa village; Amathole (Amahlathi local municipality) Ndakana village, (Ngqushwa local municipality) Mgababa village and (Mbhashe local municipality) Mbanyana village. The broad objective of the study therefore, was to evaluate the effectiveness of the extension model applied on the HVC programme as well as to identify the roles and responsibilities of different stakeholders involved in the model. The specific objectives of the study were to describe the HVC based extension model as it is currently organized and implemented in the Eastern Cape Province of South Africa in relation to the erstwhile Siyazondla programme, to establish the effectiveness of the extension model in terms of skills transfer and capacity development, to determine the socio-economic impact of the extension model on the livelihood of involved households, to establish the extent to which the extension model has empowered women and youths and to study the factors that has contributed to the sustainability of the extension model. In carrying out this research and in line with the practice of Agricultural Research for Development (ARD), qualitative and quantitative methods of information gathering were applied. Group approach such as the Rural Rapid Appraisal (RRA) and the Participatory Rural Appraisal (PRA) methods of data collection were used. These tools include semi-structured interviews, focus-group discussions, transect walks, seasonal calendars, key-informant interviews, resource maps and secondary data. A sample of 149 respondents was selected from eight villages in the OR Tambo and Amathole districts. The HVC model was analysed using qualitative approach, descriptive statistics and inferential statistics. The Is‘Baya/ARC extension model is thus said to be effective in meeting the objectives of the HVC programme due to the efficient transfer of skills and technology and its positive impact on the livelihood of the people. There was also an improvement of the income and food security status of the rural dwellers in O.R Tambo district. The regression analysis model was applied and the results of the model were significant to the highest income earned. Out of 22 explanatory variables fitted in the regression model, 12 were significant. The R² and adjusted R² are 73 percent and 68 percent respectively which shows the significance of the fitted variables in the model. The very high F value of 15.427 shows strong significance of the fitted variables to the model. The study therefore concluded that the HVC based extension model implemented by Is‘Baya and ARC was very effective in improving rural livelihoods. The study further recommended investment in infrastructure, market linkages, value adding, public-private partnerships, creation of tenure security, investigation of different funding sources, investment on agricultural research, extension of skills provided and implementation of similar model by the public sector.

This thesis analyses the highly structured and densely populated farmland surrounding Kakamega Forest (western Kenya) in a spatially-explicit manner. The interdisciplinary approach combines methodologies and technologies from different scientific disciplines: remote sensing with OBIA, GIS and spatially explicit modelling (geomatics and geographic science) with socio-economic as well as agro-economic considerations (human and social sciences) as well as cartographic science. Furthermore, the research is related to conservation biology (biological sciences). Based on an in-situ ground truthing and visual image interpretation, very high spatial resolution QuickBird satellite imagery covering 466 km² of farmland was analysed using the concept of object-based image analysis (OBIA). In an integrative workflow, statistical analysis and expert knowledge were combined to develop a sophisticated rule set. The classification result distinguishing 15 LULC classes was used alongside with temporally extrapolated and spatially re-distributed population data as well as socio-/agro-economic factors in order to create a spatially-explicit typology of the farmland and to model scenarios of rural livelihoods. The farmland typology distinguishes ten types of farmland: 3 sugarcane types (covering 48% of the area), 3 tea types (30%), 2 transitional types (15%), 1 steep terrain type (2%), and 1 central type (5%). The scenarios consider different developments of possible future yields and prices for the main agricultural products sugarcane, tea, and maize. Out of all farmland types, the ‘marginal sugarcane type’ is best prepared to cope with future problems. Besides a comparably low population density, a high share of land under cultivation of food crops coupled with a moderate cultivation of cash crops is characteristic for this type. As part of the research conducted, several novel methodologies were introduced. These include a new conceptual framework for categorizing parameter optimization studies, the area fitness rate (AFR) as a novel discrepancy measure, the technique of ‘classification-based nearest neighbour classification’ for classes which are difficult to separate from others, and a novel approach for accessing the accuracy of OBIA classifications. Finally, this thesis makes a number of recommendations and elaborates promising starting points for further scientific research
Die vorliegende Arbeit untersucht räumlich-expliziten das stark strukturierte und dicht besiedelte Agrarland um den Kakamega Wald (Westkenia). Dabei kombiniert der interdisziplinäre Ansatz Methoden und Technologien verschiedener Wissenschaftsbereiche: die Fernerkundung mit der objekt-basierten Bildanalyse (OBIA), GIS und die räumlich-explizite Modellierung (Geoinformatik und Geographie) mit sozio- und agro-ökonomische Aspekten (Human- und Sozialwissenschaft) sowie der Kartographie. Zudem steht die Arbeit in Bezug zum Schutz der biologischen Vielfalt (Biologie). Ausgehend von einer Referenzdatenerfassung vor Ort und einer visuellen Bildinterpretation wurden räumlich sehr hochauflösende QuickBird-Satellitenbilddaten, die 466 km² des Agrarlandes abdecken, mit Hilfe von OBIA ausgewertet. In einem integrativen Ansatz wurden dabei statistische Verfahren und Expertenwissen kombiniert, um einen ausgefeilten Regelsatz zur Klassifizierung zu erzeugen. Das Klassifizierungsergebnis unterscheidet 15 Klassen der Landnutzung bzw. -bedeckung; zusammen mit zeitlich extrapolierten und räumlich neu verteilten Bevölkerungsdaten sowie sozio- und agro-ökonomischen Faktoren ermöglichte es, eine räumlich-explizite Typologie des Agrarlandes zu erstellen und Szenarien zum ländlichen Auskommen zu modellieren. Die Agrarlandtypologie unterscheidet zehn Landtypen: 3 Zuckerrohr-dominierte Typen (48% des Gebietes), 3 Tee-dominierte Typen (30%), 2 Übergangstypen (15%), 1 Typ steilen Geländes (2%) und 1 zentralen Typ (5%). Die Szenarien betrachten mögliche zukünftige Entwicklungen der Erträge und Preise der Hauptanbauarten Zuckerrohr, Tee und Mais. Von allen Agrarlandtypen ist der „marginal Zuckerrohr-dominierte Typ“ am besten gerüstet, um zukünftigen Problemen zu begegnen. Bezeichnend für diesen Typ sind – neben einer vergleichsweise geringen Bevölkerungsdichte – ein hoher Anteil an Nahrungsmittelanbau zusammen mit einem gemäßigten Anbau von exportorientierten Agrarprodukten. Als Teil der Forschungsarbeit werden verschiedene neuartige Methoden vorgestellt, u.a. ein neuer konzeptioneller Rahmen für das Kategorisieren von Studien zur Parameteroptimierung, die „area fitness rate“ (AFR) als neue Messgröße für Flächendiskrepanzen, die klassifikations-basierte Nächster-Nachbar Klassifizierung sowie ein Ansatz zum Bestimmen der Güte von OBIA-Klassifizierungen. Schließlich gibt die Arbeit eine Reihe von Empfehlungen und bietet vielversprechende Ausgangspunkte für weiterführende wissenschaftliche Forschungen

Rural communities in Malawi are experiencing adverse climatic hazards which are attributed to climate variability and change. The frequent events being experienced include floods, dry spells and seasonal droughts. Rural livelihoods are severely affected because of their sensitivity to these phenomena. The research has analyzed community-based coping and adaptation strategies for sustainable livelihoods among the rural poor in Kaunda village, T/A Simlemba in Kasungu district, Malawi. The research data was collected from groups of male and female participants which also included a group of traditional leaders living in the area. The study used Participatory Rural Appraisal (PRA) methods such as Focus Group Discussions using the associated tools of resource mapping, transect walks, timelines and livelihood ranking to collect the data. The research findings have revealed that the major climate events experienced in Kaunda village are seasonal droughts and dry spells which have significantly impacted agriculture as a major livelihood activity in Malawi. The study has also revealed the community-based coping and adaptation strategies employed by the people. Recommendations made in this study have highlighted the need to support vulnerable rural communities with resilient and secure livelihoods.

The dependence of small-scale subsistence farmers on natural resources highlighted the need of a transition towards a more sustainable management of resources. An extensive literature is available on the structural factors affecting small-scale agricultural production in developing countries, while few studies are available on the role of social dynamics on the capacity of the system to react to adverse conditions. What are then the social, economic and environmental factors affecting small-scale subsistence agriculture? and, what is the effect of social behaviours on the adoption of agricultural innovation? This study is based on the specific case of eSwatini (southern Africa). A causal loop diagram was adopted to show the cause–effect relationship between variables. The role played by social behaviors in the diffusion of innovation is explored with the use of agent-based modelling (ABM). The model is based on agents, environment, links and five processes: crop production, social learning, individual learning, decision making, and resource recovery. In the simulation three farming behaviours can be adopted: no cropping, traditional practices or conservation agriculture (CA). The ABM was implemented in the Netlogo 6.2.0 platform. The case study is supported by scientific literature and interviews with local stakeholders. The results highlight the role of gender equality in the diffusion of knowledge. The model was run with and without gender equality for 10, 25 and 50 cycles representing farming seasons. The results show an increase in the spread of CA in the scenarios with no gender discrimination for which the rate of innovation adoption is faster. Moreover, the study casts light on the role of social learning and its dependence on training and education centres for the diffusion of new behaviours. Also, results show how an increase in the number of learning centres leads to a higher rate of knowledge diffusion.

Abstract Introduction: Potable water is vital for human existence, but scarce in certain areas. Purpose: The research focused on exploring Kumbo potable water on the livelihood of the rural inhabitants of the Kumbo community in the Northwest Region of Cameroon. It also examined stakeholders' involvement in the project and the sustainability of the project. Methods: The research was a descriptive qualitative case study that used in-depth individual interviews, focus group discussions and document reviews as sources of data. 21 participants were involved and they included key informants, community leaders, households, focus groups, and staff of the Kumbo water project. Informant feedback or member checking was used to as a strategy to establish validity of data collected. The Nvivo software was used for data storage, management and to facilitate analysis. Results: The findings identified 4 major themes: participants’ perspectives of accessibility of water provided by the project, stakeholders and their roles in the management of the project, social and economic factors influencing the livelihood of the Kumbo population and the sustainability of the project. Majority of the interviewed participants reported that the water project has increased the accessibility of potable water in the Kumbo community. However, stakeholders involved in the management of the project has changed over time since its inception (from the Department of Public Works, Department of Urban Development, National Water Supply Company of Cameroon (commonly known as SNEC- a French acronym), Nso Development Association (NSODA), and currently Kumbo Water Authority (KWA) and Nso Community Water). Besides the KWA and Nso Community Water currently involved in the management of the project, the Governor of the Northwest region, the Senior Divisional Officer of Bui division, the Paramount Chief of Kumbo, and the Mayor of the Kumbo Urban Council are stakeholders involved in this project. Nevertheless, all these stakeholders have undefined roles and they often make conflicting decisions on how the project should be managed. The undefined roles of these stakeholders compounded by climate change and population expulsion threatens the sustainability of this water project. These setbacks have reduced the quantity of water supplied by the project to the community; resulting in the rationing of water. Conclusion: The findings of this study have revealed that the inhabitants of the Kumbo community perceived that the water project provides accessible and clean water needed for their livelihood. Nonetheless, conflicts between stakeholders has led to the poor management of the project, and this can potentially lead to waterborne diseases in the community. To protect the health of the population, stakeholders need to come to a compromise on how to better manage this project. Also, multiple case studies of similar projects in and around the region may further highlight best practices of water governance and its benefit to rural communities in Cameroon.

Community-Based Natural Resource Management (CBNRM) is considered a win-win approach to reconcile conservation with natural resource use. CBNRM aims to accomplish conservation whilst prioritising development and contributing to poverty alleviation. This study analysed the different components of a CBNRM initiative, Bigodi Wetland Sanctuary (BWS), located in western Uganda. The study was carried out by interviewing the managing committee members (n= 8) as well as local households (n= 68) regarding the manner in which the project works, and the associated benefits and constraints. The main management issues recognised were a lack of monitoring and committee cohesiveness. The information gathered through the household survey enabled the calculation of the value of local livelihood options. This was done on the premise that conservation is better accepted when land users realise the economic value of natural resources. The average annual value of household livelihoods was represented by 30% crop production, 57% natural resource use, and 13% livestock. Lastly, wetland assessments were performed using the WET-Health and WET-EcoServices methodologies from the Wetland Management Series. These assessments indicated that the impacts of local livelihoods on the wetland were currently low but potential issues could arise with the increasing human population density. Ultimately, BWS presents both environmental and social costs and benefits. With a detailed and interdisciplinary method specific recommendations of improvement can be made to reduce such costs and further reconcile the conservation of Bigodi Wetland with local natural resource use..

Climate Change (CC) is arguably the most pressing topic of our modern society. The acceleration in magnitude and frequency of climate variability associated with it, along with the overall change of climate patterns threatens to push their adaptive capacity to breaking point, hinting at the significant impact that CC will have on the livelihoods of small-scale farmers of the developing world, and on South Africa in particular. This research project aims to investigate how local knowledge and agriculture-based coping practices of small-scale farmers of the Ebenhaeser community are adapted to deal with and attempt to reduce the vulnerability of their livelihood strategies to CC. This illustrative study followed a qualitative methodology, using qualitative data collection (in-depth and semistructured interviews, as well as special focus group discussions) and analysis (thematic ordering) methods to fulfil its aim. This study revealed that local farmers were able to identify changes in climate which were hazardous to their livelihoods and that they have been developing coping practices in response the CC. Furthermore, this analysis showed that local small-scale farmers used their local body of knowledge as a basis for the development of these coping practices, and that this local knowledge base itself has been affected by CC. An important finding of this study was the extent to which local social, historic, economic, political and physical conditions influence the sensitivity and adaptive capacity of the smallscale farmers of the Ebenhaeser community. The findings of this study opened our eyes to the realities of CC and its impacts on and adaptation efforts of small-scale farmers of the Ebenhaeser community. The study show ed that unless these issues are addressed in a comprehensive and holistic manner, there is no real prospect of sustainable, long-term CC adaption solutions for the small-scale farmers of this area, and conceivably none for many more rural communities in South Africa.

The purpose of the study was to investigate how farmers in Quang Bing Province, Vietnam have been making the transition from subsistence farming to commercial agriculture. This process began in 1986 when the Vietnam economy changed from central planning to a market orientation. The research strategy was based on case study analysis of two communes in each of three agro-ecological zones, defined as coastal, plains and mountains. Within each commune there were six embedded household case studies, i.e 36 in total. Case studies were selected purposively to capture diversity of agro-ecological zones, market access and communications, wealth and income status, and ethnic communities. Households were interviewed twice; first in either late 2006 or early 2007, and again in late 2008. The study was approached using a constructivist paradigm and a lens of livelihood analysis, focusing on resources, institutions, interventions and the dynamics of change. Particular attention was given to the development of markets (inputs, outputs, land, labour and credit) and supply chain factors. Separate measures of commercialisation were constructed based on outputs and inputs, and at the level of both individual activities and the overall household. Investigations were informed by existing theory, but no hypotheses were tested. Instead, the research focused on emergent patterns and insights, and the enrichment and modification of existing theory. A review of literature indicated that the transition from subsistence farming to commercial agriculture in Vietnam was different from other countries on account of the specific combination of low technology agriculture, typical of much of developing Asia, combined with the transformation from a centrally planned economy to a market orientation as occurred in Central and Eastern European countries. At commune level, the key determinants of commercialisation were strong physical connections to markets, with good road access being paramount. Once all weather road access for motorised vehicles was available, then rapid commercialisation occurred. Supply chains typically developed faster for outputs than inputs. New technologies that increased the yield of basic food crops, and facilitated by Government and NGO programs, led to the release of land resources no longer required for meeting food security needs. Households retained their production of food crops that provided food security, and added additional cash earning activities. At the level of individual households, the commercialisation process was led by entrepreneurial families who perceived opportunities relating to profitable activities, and combined this with hard work. Often these opportunities were linked to what they had observed or learnt elsewhere. Once first movers took up a new technology, others observed and followed. There were many enabling factors, such as access to land, access to capital, and access to credit. However, none of these could be considered a determinant, in that the absence of any one factor did not by itself preclude successful commercialisation. Absence of an active male worker was a major constraint to commercialisation, as was lack of necessary crop and livestock skills. There was evidence that income disparities were increasing between the wealthy and the poor. Output commerciality across all households averaged 88 % in 2008 and was higher for wealthy households (95 %) than poor households (83 %). All households still produced their own food crops, but these crops had low market values and hence had a low impact on the output commerciality index. Output commerciality measured in percentage terms obscured that wealthy families had net incomes almost 13 times greater than poor households. A major theoretical insight was that key commercialisation factors are multiple and context dependent. Accordingly, there is a need in any investigation for a holistic approach, based on a livelihood framework that incorporates the complexities associated with the development of markets, as well as giving consideration to the range of interventions and institutional policies that impact on livelihood development.

Crude oil is the single most utilized resource for energy and global demand is expected to increase 40 – 50 % that of current levels by the years 2025 to 2030. One renewable energy alternative is liquid biofuel, which currently is one of the fastest-growing markets for agricultural products globally. Whilst reducing environmental impact is well appreciated in developed nations, powerful drivers for stimulating the biofuel market in poorer regions of the world are socio-economic in nature. A plant of great contemporary importance is Jatropha curcas L. (Jatropha) which produces inedible oil seeds with good properties for biodiesel refinement. Promoters of Jatropha motivate that the benefits associated with this biodiesel feedstock are a solution to many of the developing world’s socio-economic problems as it generates high levels of rural employment, improves national balance of trade and stimulates both agricultural and non-agricultural sectors associated with the Jatropha-biodiesel production chain. Jatropha needs to be pruned often initially to establish higher yields, it isn’t at present harvested mechanically, it requires pesticide application and weeding, and the labour requirement during establishment is high. This labour requirement may contribute greatly to rural employment but at a significant labour cost which may undermine the profitability of growing Jatropha. This research aims to assess the economic sustainability of Jatropha-based biodiesel production as a suitable driver for rural development and in particular by modelling the maximum potential financial returns for labour. A spreadsheet based financial model was developed from life-cycle economic analysis of the Jatropha-biodiesel production chain to determine if income can support labour wages in southern Africa and India, under local wage legislation, at different yield, production cost and fuel price scenarios. The main assumption of the model was that the biodiesel sales price is proportional to the prevailing petro-diesel price. During the execution of the study it became apparent that the application of the conceptual model is strongest for India however, for comparative reasons, South Africa and Zambia were included. Results suggest that minimum legal wages in South Africa are too high to support production at the current fuel price. India and Zambia have the potential to generate profits but under specific circumstances; which are a complex function dominated by yield, labour wages, the petroleum-diesel price and the market opportunities for by-products. Financial capital is among many complex and almost unquantifiable assets to rural livelihoods, many of which compete for labour opportunity. In the 1990’s a sustainable livelihoods framework was developed by the UK Department for International Development (DFID). At the core of the framework is the “belief that people require a range of assets to achieve positive livelihood outcomes”, categorized into five different capital forms, namely; natural, human, financial, social and physical. The impacts that the biofuel industry can have on rural livelihoods in southern Africa and India can be considerable.

Inadequate attention has been paid to the complexity of rural livelihoods and the dimensions of poverty. Although progress has been achieved in poverty reduction in many countries over the years, statistics indicate that there is still much to be done. Nearly half of the population of South Africa is poor. Sustainable Livelihood Approaches see poverty reduction as achievable through diversification of livelihood strategies. Communities can benefit from the development of tourism through employment, financial gains, infrastructure creation and cultural revitalisation. While fees charged for tourism activities have the potential to contribute to locals, they are rarely controlled by them. The aim of this study was to formulate a Sustainable Livelihood Framework for Tourism (SLFT) along the African Ivory Route. The study involved fourteen villages near Fundudzi, Mtomeni and Nthubu camps which were purposively selected as they represented the three main ethnic groups in the province. Mixed method research design was used and included qualitative and quantitative approaches. A 10% sample was selected from the total number of households. Questionnaires, focus group and key informant interviews were used to collect data. The data was analysed and presented in tables, graphs and maps. The perceptions of the communities towards the African Ivory Route were both positive and negative. The benefits included, improved network, community empowerment and development of infrastructure. The constraints included, conflicts, mistrust, political interference and power struggle among the various institutions. The study concluded that the African Ivory Route has not achieved sustainable livelihoods outcomes for the concerned communities. The recommendation was that frameworks for maximising benefits from tourism were necessary to directly support community development. Communities, Institutions, Tourists and Environment (CITE) framework was conceptualised to assess the best way for attaining positive sustainable livelihoods outcomes.

abstract: Firstly, this study uses community asset mapping guided by the Community Capitals Framework (CCF) to explore the linkages between Protected Areas (PAs), tourism and community livelihoods. Secondly, it assesses changes in community needs facilitated by community participation in wildlife-based tourism in a protected area setting. Thirdly and finally, the study assesses whether the introduction of community wildlife-based tourism in a protected area as a sustainable management tool has led to the spiraling up or down of community capitals. The study adopted qualitative research method approach and made use of data collected through community asset mapping supplemented by data from focus group discussions, households, key informants, and secondary data materials that were analyzed and interpreted in light of community capital framework. The Chobe National Park (CNP) and Chobe Enclave Conservation Trust (CECT); a community living adjacent to CNP in Botswana provides the context on which this study's discussion focuses. Results indicate that the accession of Botswana from colonialism through post colonialism era intertwined considerable institutional arrangement changes in the field of protected area governance that reflects evolutionary management styles. Protected areas, tourism and community livelihoods linkages are based on many inter-dependents of community capitals relationships which are dependent on community socio-economic activities. In assessing changes in community needs, the results indicate that participation in wildlife-based tourism has brought both positive and negative changes that have implications on both the status quo for community livelihoods and protected areas, namely; the influence of changes in community capitals dynamics, mechanization and commercialization of agriculture, government funded infrastructural development, income generation, and the commodification of some of the community capitals. Finally, the increased livelihoods options and diversification dynamics, fragile wildlife-livestock co-existence, heightened human-wildlife conflicts, environmental education and awareness are the emerging themes that explain how the introduction of tourism in a protected area setting affect the spiraling up and down of the community capitals dynamics.

This study examines the process and implementation of a conservation project in Chimanimani locality, a remote rural area located in Sussundenga district in the central province of Manica. The Chimanimani Transfrontier Conservation Area Project, as the Project became known, was one of the conservation area projects established in three provinces of Mozambique (Maputo, Gaza and Manica1) in the years following the civil conflict. In essence the Chimanimani Project was framed to enhance environmental sustainability of the targeted areas and contribute to poverty reduction through sustainable use of local natural resources. Accordingly, it was seen as a way of improving the overall quality of life of the targeted communities. The study analyses the Project efforts of utilizing the synergies between conservation and community development in rural areas where income-earning opportunities are limited. The research has focused on two of the five Chimanimani communities (Nhaedzi and Moribane) and brings to the fore evidences of the factors that have affected either positively or negatively the success of the Project.

Since 1998, the communities of Combomune in Southern Mozambique have participated in a project intended to improve the quality of their lives, while ensuring the natural resources they depend on are well managed and sustainably used. The approach employed is Community-Based Natural Resource Management (CBNRM). CBNRM is the resource conservation and management approach which has emerged as one of the models to involve local communities, previously excluded from conservation and management of natural resources and rural development programs. This model promotes community participation, responsibilities and benefit sharing among stakeholders involved in natural resource management programs. A case study was conducted to assess the impacts of the Combomune CBNRM project on household livelihoods and on the environment. The Combomune CBNRM project is meant to improve the household livelihoods of the Madliwa, Hochane and Chaves communities involved in the management of indigenous forest resources. The involved communities derive direct and indirect benefits from the CBNRM project. These benefits have impacts on household livelihoods and on the environment. The most noted benefits are social and economic changes. These changes have positively affected the living conditions of the involved communities. Further, the study revealed the Combomune CBNRM project charcoal production was the only activity generating monetary income to individual and to community development funds. Monetary income was invested in the improvement of homesteads, the purchase of domestic animals and the development of infrastructure with a high social impact. Water supply, education, health care and household homestead improvements were the major project achievements. The project encouraged environmental friendly practices such as sustainably agricultural activities and a fire management program. Local residents were also encouraged to plant trees on bare soil to protect it from being eroded. The study has not deeply explored the CBNRM project impacts, therefore more case studies are recommended to further explain effective CBNRM project contributions to household livelihoods, so it may be reasonably promulgated as a strategy not only devoted to involve local communities or merely for resource conservation, but as the approach which improves livelihoods of the rural poor.

Forestry and the wood-based sector provide increasing contributions to the national and rural economy development. Tree plantations serve as a business opportunity to secure the livelihood of thousands of small-scale timber producer households in several tropical countries. Given that forest land and the timber production it supports is limited, sustainable management of forest-based resources including timber is required. By integrating the value chain and livelihood analysis framework, this study investigates the value chains and impacts on rural livelihoods of commercial Acacia hybrid timber in central Vietnam. Besides that, scenario analysis is applied with a view to proposing the development pathways of the timber value chains and to providing improved information for developing the plantation policy in Vietnam at large. The empirical analysis employs a case study research design to examine the transition towards higher value uses of timber resources, thereby exploring the performance of woodchip, non-FSC furniture and FSC-certified furniture value chains in Thua Thien Hue province. Furthermore, two production areas named Nam Dong and Phu Loc districts are selected as embedded cases to examine the rural development potentials of Acacia hybrid timber production and commercialization. A mix-method approach, including both qualitative such as review and analysis of secondary data and key informant interviews, and quantitative data collection methods such as producer household surveys are applied to gather primary and secondary data. Diverse qualitative and quantitative analyses including content analysis, value chain analysis, livelihood analysis, and scenario analysis are also utilized corresponding to the specific research objectives. The macro-level analysis reveals the strategic responses of Asian wood-based firms to the global economy, particularly in terms of geographical scope, governance, cooperation, and overall performance. In addition, a literature review points out the potential impacts of Asian timber VCs on the environment and livelihoods. While timber product commercialization generates benefits to the value chain actors, unsustainable forest management leads to diverse negative environmental effects. The findings demonstrate considerable knowledge gaps and call for broader geographic coverage, as well as more transparent and quantitative assessments. To deepen the understanding on timber VCs, further research efforts should scrutinize the origins, functions, operations, and interactions of firms in these chains, and incorporate environmental and social aspects. The meso- and micro-level analysis exposes the structure of Acacia hybrid timber value chains which are shaped by various socio-economic, political, and environmental conditions. All three analyzed timber value chains are buyer-driven, led by processing and exporting companies in the downstream node of chains. At the upstream node, small-scale timber producers are normally less organized and lack market access. Timber production and commercialization provide profitable business activities to timber producers, traders, and processing and exporting companies. From a chain perspective, the woodchip value chain is financially profitable. However, its contribution to the national economy is the least. In contrast, the FSC-certified furniture value chain contributes fundamentally to economic development. The micro-level analysis indicates the difference regarding the socio-economic features, resource access, and management of producer households between the two analyzed districts. Relevant findings also indicate the importance of Acacia hybrid woodlots in the current livelihood system. However, more wealthy households benefit more from the Acacia hybrid timber income, especially in a well-developed market. Timber production and commercialization contribute to rural poverty reduction. Nevertheless, it is the main driver of the overall income inequality in both districts. Results from the literature review and empirical study support to conceptualize and evaluate the three development scenarios, displaying different levels of forest transition interventions and reactions of key actors in the chains. Under the current situation, a fast transition model with strict plantation control is not advisable for timber value chains’ stakeholders, especially those who operate on the ground. A slow transition scenario with a co-management model, instead, serves as a suitable development pathway. To improve the current management system, this study implies five management strategies, including (i) adaptive management; (ii) multi-stakeholder cooperation; (iii) target interventions; (iv) collaborative management and (v) integrated planning. The study can be of interest for further policy interventions focusing on sustainable reforestation and livelihood development in Vietnam. The approach of transition towards high added value products can further be applied in other comparable contextual cases searching for sustainable utilization of timber and forest-based products at large. Theoretically, the thesis highlights that sustainable management of forest-based products will not be obtained unless the related economic, social, and environmental aspects are considered in conjunction. These conditions are driven by several factors, such as national policy frame and market condition. Therefore, it is crucial to understand the interrelations within the economic-socio-ecological system to achieve long-term development targets.
Die Forstwirtschaft und der holzverarbeitende Sektor leisten einen wachsenden Beitrag zur nationalen und ländlichen Wirtschaftsentwicklung. Baumplantagen dienen Tausenden von kleinen Holzproduzentenhaushalten in vielen tropischen Ländern als Geschäftsmöglichkeit, um ihren Lebensunterhalt zu sichern. Da die Waldflächen und die darauf gestützte Holzproduktion begrenzt sind, ist eine nachhaltige Bewirtschaftung der waldbasierten Ressourcen, einschließlich Holz, erforderlich. Diese Studie untersucht die Wertschöpfungsketten und die Auswirkungen von kommerziellem Akazien-Hybridholz auf den Lebensunterhalt der ländlichen Bevölkerung in Zentralvietnam durch Integration von Wertschöpfungsketten- und Lebensunterhaltsanalysen. Außerdem wird eine Szenarioanalyse durchgeführt, um Entwicklungswege für die Holzwertschöpfungsketten vorzuschlagen und bessere Informationen für die Entwicklung der Plantagenpolitik in Vietnam insgesamt bereitzustellen. Die empirische Analyse verwendet ein Fallstudien-Forschungsdesign, um den Übergang zu höherwertigen Nutzungen von Holzressourcen zu untersuchen und dabei die Leistung von Wertschöpfungsketten für Hackschnitzel, nicht FSC-zertifizierte Möbel und FSC-zertifizierte Möbel in der Provinz Thua Thien Hue zu analysieren. Darüber hinaus werden zwei Produktionsgebiete, die Distrikte Nam Dong und Phu Loc, als Fallbeispiele ausgewählt, um die ländlichen Entwicklungspotenziale der Akazien-Hybridholzproduktion und -vermarktung zu untersuchen. Um Primär- und Sekundärdaten zu sammeln wird ein Methodenmix aus qualitativen Methoden, wie der Sichtung und Analyse von Sekundärdaten und der Befragung von Schlüsselinformanten, sowie quantitativen Datenerhebungsmethoden, wie der Befragung von Produzentenhaushalten, verwendet. Außerdem werden diverse qualitative und quantitative Analysen wie Inhaltsanalyse, Wertschöpfungskettenanalyse, Lebensunterhaltsanalyse und Szenarioanalyse entsprechend den spezifischen Forschungszielen eingesetzt. Die Analyse auf der Makroebene zeigt die strategischen Reaktionen der asiatischen Holzfirmen auf die globale Wirtschaft, insbesondere in Bezug auf geografische Reichweite, Governance, Kooperation und Gesamtleistung. Darüber hinaus zeigt eine Literaturübersicht die potenziellen Auswirkungen asiatischer Holzwertschöpfungsketten auf die Umwelt und die Lebensgrundlagen der lokalen Bevölkerung auf. Während die Kommerzialisierung von Holzprodukten Vorteile für die Akteure der Wertschöpfungskette mit sich bringt, führt eine nicht nachhaltige Waldbewirtschaftung zu diversen negativen Umwelteffekten. Die Ergebnisse zeigen erhebliche Wissenslücken auf und fordern eine breitere geografische Abdeckung sowie transparentere und quantitativere Bewertungen. Um das Verständnis von Holz-Wertschöpfungsketten zu vertiefen, sollten weitere Forschungsarbeiten die Ursprünge, Funktionen, Abläufe und Interaktionen von Unternehmen in diesen Ketten untersuchen und dabei ökologische und soziale Aspekte mit einbeziehen. Die Analyse auf der Meso- und Mikroebene legt die Struktur der Akazien-Hybridholz-Wertschöpfungsketten offen, welche von verschiedenen sozioökonomischen, politischen und ökologischen Bedingungen geprägt sind. Alle drei analysierten Holzwertschöpfungsketten sind käufergesteuert, angeführt von Verarbeitungs- und Exportunternehmen im nachgelagerten Knotenpunkt der Ketten. Am vorgelagerten Knotenpunkt sind die kleinen Holzproduzenten in der Regel weniger organisiert und haben keinen Marktzugang. Die Holzproduktion und -vermarktung bieten profitable Geschäftsaktivitäten für Holzproduzenten, Händler sowie Verarbeitungs- und Exportunternehmen. Aus der Kettenperspektive ist die Wertschöpfungskette Hackschnitzel finanziell profitabel. Ihr Beitrag zur Volkswirtschaft ist jedoch der geringste. Im Gegensatz dazu trägt die FSC-zertifizierte Möbel-Wertschöpfungskette grundlegend zur wirtschaftlichen Entwicklung bei. Die Analyse auf der Mikroebene zeigt die Unterschiede zwischen den beiden analysierten Distrikten in Bezug auf die sozioökonomischen Merkmale, den Ressourcenzugang und das Management der Produzentenhaushalte. Relevante Ergebnisse weisen auch auf die Bedeutung von Akazien-Hybridholzplantagen im derzeitigen Lebensunterhaltssystem hin. Allerdings profitieren wohlhabendere Haushalte mehr von den Einnahmen durch Akazien-Hybridholz, insbesondere bei einem gut entwickelten Markt. Holzproduktion und Kommerzialisierung tragen zur ländlichen Armutsbekämpfung bei, dennoch ist sie der ausschlaggebende Kraft für die allgemeine Einkommensungleichheit in beiden Distrikten. Die Ergebnisse der Literaturrecherche und der empirischen Studie helfen dabei, die drei Entwicklungsszenarien zu konzipieren und zu bewerten, die unterschiedliche Ebenen der Waldumwandlungsmaßnahmen und Reaktionen der Hauptakteure in den Ketten darstellen. In der aktuellen Situation ist ein schnelles Übergangsmodell mit strikter Kontrolle der Plantagen für die Akteure der Holzwertschöpfungsketten nicht ratsam, insbesondere für diejenigen, die vor Ort tätig sind. Ein langsames Übergangsszenario mit einem Co-Management-Modell dient stattdessen als geeigneter Entwicklungspfad. Um das derzeitige Managementsystem zu verbessern, schlägt diese Studie fünf Managementstrategien vor, darunter (i) adaptives Management, (ii) Zusammenarbeit mehrerer Interessengruppen, (iii) gezielte Interventionen, (iv) kooperatives Management und (v) integrierte Planung. Die Studie kann für weitere politische Interventionen von Interesse sein, welche sich auf eine nachhaltige Wiederaufforstung und die Entwicklung der Lebensgrundlagen in Vietnam konzentrieren. Der Ansatz des Übergangs zu Produkten mit hoher Wertschöpfung kann auch in anderen vergleichbaren Fällen angewandt werden, in denen eine nachhaltige Nutzung von Holz- und Forstprodukten im Allgemeinen angestrebt wird. Theoretisch unterstreicht die Arbeit, dass eine nachhaltige Bewirtschaftung von Forstprodukten nur dann erreicht werden kann, wenn die damit verbundenen wirtschaftlichen, sozialen und ökologischen Aspekte in Verbindung betrachtet werden. Diese Bedingungen werden von verschiedenen Faktoren beeinflusst, wie z.B. dem nationalen politischen Rahmen und den Marktbedingungen. Daher ist es entscheidend, die Zusammenhänge innerhalb des ökonomisch-sozio-ökologischen Systems zu verstehen, um langfristige Entwicklungsziele zu erreichen.

This study is a contribution to the research projects in Africa that are concerned with the analysis of the various conflicts that currently face the continent. Political, ethnic, religious, cultural, and other forms of conflicts have increased in number over the past five decades. The academic community has been making its contribution to the understanding and resolution of the conflicts through its research projects. The contributions of the academic community are widely acknowledged in this regard. This study is about those conflicts emanating from differences in the cultural interpretations of natural resources between crop farmers and nomadic herdsmen. The example selected belongs to those conflicts, which are entrenched in the cultural practices of rural communities. These conflicts are unique, since most of them predate the political, economic, and ethnic-based conflicts, most of which have emerged since the colonial era. Understanding these types of conflicts thus constitutes an important area of the development process of countries such as the Republic of Sudan, which already has many conflicts to contend with. The areas elected the North, South and West Kordofan States constitute some of the conflict hotspots of the Republic of Sudan in terms of the cultural-natural resource conflict dynamics. The understanding and resolution of the conflicts between the crop farmers and nomadic herdsmen in the region have the potential to offer enormous benefits to the peace needed for the long-term development of Sudan. The objectives of this study were chosen purposely to contribute to the research projects on the peace-conflict discourse of the Republic of Sudan. They were aimed at finding out how the cultures of the crop farmers and nomadic herdsmen of the Greater Kordofan states explain the conflicts and the efforts of the Sudanese authorities to help address them. The critical realist research approach has been selected as the framework for the study. This involved a number of steps. First, information on the nature of the current policies and plans of the government of Sudan to address the conflicts has been collected as one basic element of the challenge of development of the Greater Kordofan region. The challenge has been discussed in terms of the gap currently existing between the government’s peace building plan objectives on the one hand and the actual outcomes on the other. Next, information was collected from the relevant stakeholders on the reasons for the persistence of the conflicts between the nomadic herdsmen and the crop farmers despite the efforts on the part of the government at building peace between them. Generating information in this way led to the recommendation that the stakeholders identified in this study hold the key to the success of the attempts at building long-term peace between the crop farmers and the nomadic herdsmen of the Greater Kordofan States. The recommendations of the study are based on the idea that opportunities always exist for the stakeholders to introduce positive change in their society.
