Investigating the influence of climate change, conflict and development interventions on livelihood resilience in pastoralist societies : a multiple case study of the Borana and Samburu

Chamberlain, Natasha Arlene January 2014 (has links)
East African pastoralist societies are characterised by their inherent adaptability to climatic variability, by way of their sophisticated resource management systems and social institutions which provide the knowledge and flexibility needed to respond effectively to risk and uncertainty. However, the impacts of future climate change, in addition to the myriad of social, political, economic and environmental pressures associated with integrating into an increasingly inter-connected globalised system, may be unprecedented in their scope and range, and are likely to undermine their ability to pursue successful livelihoods while putting at risk the things they value. Responses to these challenges need to be based on an accurate and evidence-based understanding of the complexity and synergistic nature of multiple stressors, in order to avoid narrow quick-fix solutions which may undermine resilience and human security in the longer term. This social science research has used a multi-methods approach to fulfil the following objectives: identify the range of stressors impacting livelihoods and wellbeing within the study areas; investigate the multi-directional associations between climate variability and conflict; and evaluate the influence of development interventions on the characteristics of social resilience. Fieldwork was undertaken in collaboration with two non-governmental organisations, with data derived from ethnographic observations and shadowing, participatory rural appraisal, focus group discussions, semi-structured interviews and household livelihood surveys. Results find that communities within the study areas are faced with multiple and interacting pressures on their lives and livelihoods, and that while climate change impacts are likely to compound vulnerability and undermine human security, they cannot be isolated from the broader context, or from local priorities and lived realities. Violent conflict is identified as being more closely associated with periods of abundant rainfall than those of scarcity or resource competition, with climate-related hazards such as drought being more likely to result in reconciliation and cooperation. Conflict is driven primarily by the broader political economy within the region, along with land boundary disputes and the ethnically-based nature of governance and resource allocation. Pastoralist systems are found to inherently contain many of the characteristics of socio-ecological resilience, with development interventions having the potential to build on these strengths in order to simultaneously promote adaptive capacity and build peace. However, the narrow focus on specific risks by organisations within the study areas, without a broader integration of responses to multiple stressors, may lead to path dependency and maladaptation, and could act to undermine resilience in the longer term. This thesis contributes qualitative empirical evidence to the climate security debate, and demonstrates that peace and cooperation are more likely outcomes than violence in pastoralist regions during periods of climate-related stress. It also provides an analysis of the extent to which development interventions inherently support or constrain adaptive capacity and social resilience to climate change, conflict, and other livelihood pressures.

Hunting as a conservation tool : investigating the use of hunting in CBNRM programs : a case study of the Ntabethemba Community Reserve, South Africa.

Gird, Justin William 04 1900 (has links)
Thesis (MSc)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: The conservation of resources which fall under communal tenure has been a major dilemma for the past 60 years. In South Africa communal lands support more than a quarter of the country’s citizens, mostly the poorest members of society whose livelihoods rely heavily on natural resources. Wildlife enterprise is an alternative land use strategy for implementing community based resource management on communal lands. Additionally, safari hunting has been recognised as an efficient means of initiating wildlife based land use practises. In the 1980’s a community owned game reserve, which utilised safari hunting as an income source, was established on one of South Africa’s black homelands, the Ciskei. Since then, the reserve has been disbanded but little is known about how it operated, the reason it was formed or why it failed. The aim of this study was twofold: firstly, to document and understand the happenings of a failed community owned hunting reserve in South Africa’s Eastern Cape Province and secondly, to determine what level of support there would be amongst the local residents if the reserve was to be re-established. Semi structured, qualitative interviews were conducted to gather information about the reserve from key informants. Structured, randomly selected household surveys were used to gauge local residents support on the idea of having the reserve re-established. Additionally, in doing so it was possible to view, though indirectly, the thoughts and attitudes of the residents to the notion of safari hunting as a land use option. In review of the reserve history it was found that complexities that make up the social settings of communal lands in South Africa were ignored and dealt with through the age-old approach of top-down management regimes. Once the power of the initial authorities was lost the entire project was doomed to failure as local residents felt no need to keep the project alive. Results showed that 73.7% of the respondents would support the redevelopment of the Ntabethemba Reserve while 19.5% would not. The remaining 6.8% could not say whether they would or would not. The majority of the respondents (73%) believed that the area should be marketed for safari hunters, whilst 13% were against it, 9% were neutral and 5% were unsure. The Ntabethemba Reserve can be viewed as a ‘joint-management’ project where management responsibilities were adopted by a non-community party. If a future project is to be undertaken it needs to be aware of the complex socio-ecological setting of the area and account for this in ways that are beyond those advocated in the traditional approach to protected area conservation. The highly skewed distribution of livestock ownership needs to be taken into consideration in that those few individuals who own the most livestock would lose the most from any development that reduces grazing lands. Both the benefits and the costs need to be distributed in such a way that a situation is avoided where only a few are benefiting at the expense of others. / AFRIKAANSE OPSOMMING: Die bewaring van hulpbronne in gebiede met kommunale grondregte is reeds vir die afgelope 60 jaar uiters problematies. In Suid-Afrika is meer as ‘n kwart van alle landsburgers afhanklik van kommunale grondgebiede vir hulle lewensonderhoud. Dit is hoofsaaklik die armste lede van die gemeenskap wat op die natuurlike hulpbronne in hierdie gebiede staatmaak. Natuurlewe-ondernemings bied ‘n alternatiewe strategie vir grondverbruik, wat die implementasie van gemeenskapsaangedrewe hulpbronbestuur op kommunale grond moontlik maak. Daarmee gepaard, is safari-jag ‘n erkende en effektiewe metode om praktyke rondom natuurlewe-gesentreerde grondverbruik te inisieer. Gedurende die 1980’s is ‘n natuurreservaat met gemeenskapsregte in een van Suid-Afrika se swart tuislande, naamlik die Ciskei, gevestig. Safari-jag is as inkomstebron in hierdie reservaat benut. Die reservaat is sedertdien ontbind. Daar is egter min inligting oor hoe die reservaat bedryf is, oor die redes waarom dit geskep is, of waarom dit misluk het. Hierdie studie was tweedoelig: eerstens om die gebeure rondom ‘n mislukte jagreservaat met gemeenskapsregte in die Oos-Kaapprovinsie te dokumenteer en te begryp, and tweedens, om te bepaal of, en in hoe ‘n mate, die plaaslike inworners die hervestiging van die reservaat sou ondersteun. Half-gestruktureerde, kwalitatiewe onderhoude is gevoer om inligting oor die reservaat van sleutelinformante in te win. Gestruktureerde, ewekansig geselekteerde huishoudelike steekproewe is gedoen om die steun vir die moontlike hervestiging van die reservaat te peil. Op indirekte wyse was dit verder moontlik om inwoners se houdings en benaderings tot safari-jag as grondverbruikerskeuse te evalueer. Toe die geskiedenis van die reservaat in oorsig geneem is, is bevind dat die ingewikkelde sosiale agtergrond van gemeenkappe met kommunale grondregte in Suid-Afrika verontagsaam is, en dat die afgeleefde bestuursbenadering “van-bo-af-ondertoe” ook hier gebruik is. Toe die eermalige owerhede al hulle uitvoerende magte verloor het was die projek tot mislukking bestem, omdat die plaaslike inwoners geen rede gesien het om dit aan die lewe te hou nie. Die resultate het getoon dat 73.7% van die respondente die herontwikkeling van die Ntabethemba Reservaat sou ondersteun, terwyl 19.5% dit nie sou doen nie. Die oorblywende 6.8% kon nie sȇ of hulle ten gunste daarvan was of nie. Die meerderheid van die respondente (73%) is van mening dat die gebied as safarijaggebbied bemark moet word, terwyl 13% daarteen was, 9% neutraal en 5% onseker was. Die Ntabethemba-reservaat kan eerder as ‘n projek van “gesamentlike-bestuur” beskou word, as ‘n inisiatief wat uiteraard op “kommunaal-gebaseerde natuurlike hulpbronbestuur” (CBNRM) gegrond is. As ‘n projek in die toekoms weer geloots word, moet sorgvuldig ag geslaan word op die ingewikkelde sosio-ekologiese agtergrond van die gebied. Dit mag nie, soos in die verlede, bloot volgens die tradisionele benadering tot die bewaring van beskermde gebiede van stapel gestuur word nie. Die erg skewe verspreiding van veebesit is uiters belangrik in hierdie konteks, aangesien die paar individue wat die meeste vee besit, die grootste verliese sal moet dra as ‘n ontwikkeling plaasvind wat weidingsverliese behels. Beide voordele en verliese moet opgeweeg en eweredig versprei word, sodat ‘n paar mense nie ten koste van ander begunstig word nie.

Finding Balance: Determining The Relationship Between “Economic Development," Traditional Knowledge and Natural Resource Management in the Context of the Nova Scotia Mi’kmaq

WHITMAN, ZABRINA 10 September 2013 (has links)
Indigenous societies discuss the importance of Mother Earth for their well-being and many are working to regain control of their lands and waters and how they are used. Critically, many state that land access strengthens culture and traditional (ecological) knowledge. In this research I tried to determine if the reality reflects the rhetoric, looking particularly at how the concepts of economic development and traditional knowledge interact with each other, and impact Indigenous resource management. The case study focused on the Nova Scotia Mi’kmaq, examining the process of management implementation at a macro level. Sixteen semi-structured interviews took place in nine of thirteen communities. The results illustrated that economic development is necessary for Mi’kmaq sustainability and community sustenance, but also economic development is a needed political tool to gain power with the state. Further, traditional knowledge is connected to land management. With the loss of this knowledge due to colonialism and a greater influence of mainstream western liberal thought, respect for the land is reduced and this impacts Indigenous resource management practices. These factors also negatively impact relations between individuals and within the community as a whole. For true (Mi’kmaq) sustainability, resource management strategies should be based on Mi’kmaq values and practices and be wary of capitalist tendencies. / Thesis (Master, Global Development Studies) -- Queen's University, 2013-09-08 13:03:57.366

Keeping track of nature : interdisciplinary insights for participatory ecological monitoring

Farquhar, Samantha Clair January 2012 (has links)
Participatory ecological monitoring aims to bring together conservationists and members of the public to collect scientific data about changes in nature – in species, habitats, ecosystems and natural resources. Given that such monitoring not only concerns measures of nature but inherently the participants doing the measuring, it is as much to do with social processes as it is to do with ecological ones. By drawing on detailed ethnographic work from the community forests of Nepal, this thesis aims to explore some of the social dimensions of participatory monitoring and of its consequences for socio-ecological regimes. Current debates in political ecology, development studies and nature-society studies provide the theoretical basis for the investigation. The novelty of the thesis lies in its extensive empirical data, which allows it to explore current understandings of participatory monitoring. The thesis establishes the following tentative theoretical findings. It firstly draws attention to the importance of the informal, often unconscious ways in which we all observe changes in nature and of the need to recognise such ‘local monitoring’ in relation to participatory monitoring. It draws attention to the situated nature of practices of monitoring and the heterogeneity of people involved, suggesting that this has consequences for how costs and benefits arising from participatory monitoring are distributed amongst participants and beyond. It argues that without attending to such consequences, participatory monitoring may serve to (re)produce social inequalities which are the basis for marginalisation and that it may become embroiled in local power struggles. The thesis argues that whilst participatory monitoring may provide useful data on changes in nature, that this information will not automatically influence decision-making over nature conservation or the use of natural resources. A multitude of other factors are important in such decision-making and the ways in which these relate to and potentially constrain the effectiveness of participatory monitoring are discussed. The thesis finally offers a typology with which to better understand the complexity amongst participatory monitoring projects – based on who and what they are for – and with which to approach the conflicts and inconsistencies they present. The thesis concludes that without a careful consideration of their inherent social dimensions, participatory monitoring projects will ultimately fail in attempts to both improve the condition of nature and the lives of societies that depend on it, for the two are intimately connected. Interdisciplinary studies such as this are therefore seen to offer great potential to participatory and community-based approaches to conservation and natural resource management more widely.

A Socio-ecological Assessment of Watershed Ecosystem Services in Southern Patagonia

Zagarola, Jean-Paul Aguirre 08 1900 (has links)
This thesis utilizes a theoretical framework which links biophysical and social domains of ecosystems via ecosystem services (ES), in order to conduct a socio-ecological assessment of urban watersheds in three communities in Chilean and Argentine regions of southern Patagonia. Results from this study show that expanding urban areas may be undermining the ability of local watersheds to provide for high quality ES posing potential risks to community wellbeing. Secondly, researchers and decision makers influencing regional natural resource management share similar values to general community members but do not capture the diversity of values that exist within the broader community, and dialogue between these groups on management issues is poor. A community-based management structure is recommended for the creation of adaptive and locally relevant management strategies.

Natural Resource Abundance and the Inclusion of Natural Resource Management in Intrastate Peace- and Ceasefire Agreements

Mattsson, Frida January 2018 (has links)
Previous research has not specified the puzzling occurrence of the low prevalence of natural resource management (NRM) in intrastate peace- and ceasefire agreements. The purpose of this thesis is to address this gap by applying the theoretical perspectives on high natural resource abundance. High natural resource abundance produces conditions for poor economic management, which may serve as a possible explanation of the low prevalence of NRM. The result of the study indicates a negative correlation between high natural resource abundance and an inclusion of NRM in intrastate peace- and ceasefire agreements. Thus, the hypothesis “If a high level of natural resource abundance exits, there is a lower probability of an inclusion of NRM in intrastate peace- and ceasefire agreements” is upheld. Since the assumptions of the theories do appear to hold, the thesis offers findings that further our understanding of the low prevalence of NRM in intrastate peace- and ceasefire agreements.

Understanding how crop insurance impacts adoption of conservation practices

Michelle R Hemler (7479974) 17 October 2019 (has links)
In recent years, agricultural magazine articles have positioned crop insurance requirements as a barrier to conservation adoption. Our research uses a mixed-methods design with Midwest conventional corn farmers to identify if crop insurance is a hindrance to adoption. Qualitative data was analyzed in Nvivo using thematic coding and quantitative data was analyzed using Stata statistical software. Our results indicate that crop insurance is not a direct barrier to adoption. Rather, farmers identify distinct and complimentary outcomes for risk-management from participating in both crop insurance and conservation. These findings reflect broader perspectives on Midwest conventional corn producers’ beliefs and rationale for using crop insurance and/or conservation practices.

A Multi-Period Mixed Integer Linear Programming Model for Desalination and Electricity Co-generation in Kuwait

Alqattan, Nael Abdulhameed 26 June 2014 (has links)
Water is the root of life and the engine that drives agriculture, industry, economy and services. The demand for water often necessitates desalination, particularly in arid coastal environments where there are several desalination technologies in use today such as Multi-Effect Distillation (MED) and Reverse Osmosis (RO). The key utility requirement for technologies such as desalination and population in general include energy in one form or another. Therefore, desalination and co-generation are often integrated. Another key utility is electricity which is generated from either renewable or non-renewable sources. The demands for water and electricity change over time and are subject to uncertainty. In this dissertation, a country-wide large-scale energy and water cogeneration planning model for Kuwait was proposed and solved. Five different plant technologies where the planning horizon used was set to 37 years starting in year 2014 and until 2050. A Mixed Integer Mathematical programming model was proposed and formulated using General Algebraic Modeling System (GAMS), the resulting model was solved using the CPLEX solver engine. In this research obtained detailed data on the consumption on water and energy in Kuwait and performed time series analysis of the population growth and individual behavior of water and energy consumption and novel method to represent cogeneration plants was implemented in the proposed mathematical programming model. ix A modeling framework that involves a data spreadsheet and a proprietary model was implemented. The data spreadsheet and the model were formulated as a template that can receive data from different applications. In addition, automation using Visual Basic for Application (VBA) was made to the data spreadsheets such that the data is sent to the model template, Gams-Cylix, and are written back to the spreadsheet. An analysis was made between oil-based plants, natural gas (NG) plants, and solar-based plants for co-generation. It was found that for water production solar-based plants can supply 50 percent or more of the demand during after period 2020 and after implementation and for electric power generation solar plants are limited. The results indicate the preferred technology for energy generation was NG-RO. With the implementation of solar based plants the electric power load is distributed among the technologies. NG-RO plants are more scalable and therefore were expanded to cope with the future demand. The percentage of the electric power supplied by solar plant was below 35 percent across the planning horizon. By the end of the planning horizon the percentage of electric power supplied by solar base plants was nearly 20 percent. Near 70 percent of the electric power was supplied by NG RO by period 2050. Other technologies had a representation of less than 10 percent by the end of the planning horizon.

Implementing a relational worldview: Watershed Torbay, Western Australia – connecting community and place

louiseduxbury@westnet.com.au, Marie-Louise Duxbury January 2007 (has links)
The Australian landcare movement is considered to be a major success, with an extensive community landcare network developed, raised levels and depth of awareness, and a range of demonstration projects undertaken. It has inspired people across Australia and has been emulated overseas. However, negative trends in environmental conditions continue unabated. If the approach of the Australian landcare movement to date has not addressed the current unsustainable farming practices, what approach will? This Australian study explores the history of the ‘mechanistic’ worldview, its influence on the attitudes to and treatment of landscapes and indigenous knowledge from colonisation, and the ongoing impacts on current social and natural rural landscapes. Increasing tension between the mechanistic worldview and the growing landcare ethic based on relationships is apparent. Through the focus project, Watershed Torbay, a different way of seeing and treating the world is explored by praxis. A worldview based on relationships and connection as the end purpose is proffered. Strengthening connection with one’s own moral framework, and relationships with people and place in community, are seen as the path to achieving sustainability based on ecological and values rationality. It is recognised that there are multiple ways of seeing and experiencing the world, and it is important to give voice to all players with a connection to decision making. This also means that there are different forms of knowledge; these can be grouped under the typology of epistemic or scientific knowledge, techne or technical/practical capability, and the central form of knowledge about values and interests. I have worked with the focus project as a reflective practitioner undertaking action research; this is evident in the movement between theory and practice through the thesis. The thesis concludes in praxis taking the learning from the focus project, and exploration of theory, to answer the question posed at the outset by outlining how the relational worldview can be applied to the regional bodies now delivering major landcare programs.
