Thesis (DPhil (Geography and Environmental Studies))—University of Stellenbosch, 2007. / Background The Disaster Management Act (Act 57 of 2002) instructs a paradigm shift from preparedness, response and recovery towards risk reduction. In order to plan for and mitigate risks, all spheres of government must firstly assess their hazards, vulnerabilities, capacity to cope and therefore risks. Studies in this regard, in South Africa, have however only focussed on current risks. Climate Change has now been accepted by leading international studies as a reality. Climate change can impact upon many aspects of life on earth. Studies to quantify the impact of climate change on water resources, biodiversity, agriculture and sustainable development are steadily increasing, but human health seem to have been neglected. Only general predictions, mostly regarding vector-borne disease and injury related to natural disasters are found in literature. Studies in South Africa have only focussed on malaria distribution. Most studies, internationally and the few in South Africa, were based on determining empirical relationships between weather parameters and disease incidence, therefore assessing only the hazard, and not the disaster risk. Methodology This study examines the impact of climate change on human health in the Western Cape, within the context of disaster management. A qualitative approach is followed and includes: · A literature overview examining predicted changes in climate on a global and regional scale, · A discussion on the known relationships and possible impacts climate change might have on human health, · A disaster risk assessment based on the status quo for a case study area, the Cape Winelands District Municipality, · An investigation into the future risks in terms of health, taking into account vulnerabilities and secondary impacts of climate change, resulting in the prioritisation of future risks. · Suggestions towards mitigation within the South African context. Results The secondary impacts of climate change were found to have the larger qualitative impact. The impact of climate change on agriculture, supporting 38% of the population can potentially destroy the livelihoods of the workforce, resulting in poverty-related disease. Other impacts identified were injuries and disease relating to temperature, floods, fire and water quality. Conclusion Risk is a function of hazard, vulnerability and capacity to cope. The impact of an external factor on a ‘spatial system’ should be a function of the impacts on all these factors. Disasters are not increasing because of the increase in the frequency of hazards, but because of the increasing vulnerability to hazards. This study illustrated that the major impacts of the external factor could actually be on the vulnerabilities and the indirect impacts, and not on the hazard itself. Climate change poses a threat to many aspects of the causative links that should be addressed by disaster management, and its impacts should be researched further to determine links and vulnerabilities. This research also illustrates that slow onset disasters hold the potential to destroy just as much as extreme events such as Katrina, Rita or a tsunami. It also reiterates that secondary impacts may not be as obvious, but are certainly not of secondary importance.

Water Quality Management is one of the critical challenges currently facing South Africa. The triad of water resource management, socio- economic development and environmental sustainability are key issues that require balance and compromise. The effects of anthropogenic activities on the Blesbokspruit catchment were examined. Water samples were collected from nine strategically selected sites along the stream for a period of ten months in six weekly intervals and analysed for physio-chemical, selected trace metals and microbial entities. Results revealed that variables of concern were Electrical Conductivity (EC), Total Suspended Solids (TSS), Nitrates, Phosphates, Sulphates and Chemical Oxygen Demand (COD). Mean levels of these parameters in this order ranged from 93.0-146.63mS/m; 11.25-39mg/L; 0.16-2.01mg/L; 0.5-0.96mg/L; 118.63-379.5mg/L and 15.0-34.0mg/L respectively. Levels of E. coli and F. coliforms also ranged from 19.13- 43999.125 cfu/100mL and 20.63-16878.5 cfu/100mL respectively which were of concern. Levels of analysed trace metals were tolerable except for Fe with a range of 0.04- 0.73mg/L. Generally, the results from this study indicate that the river is contaminated and therefore not suitable for direct human consumption as well as for irrigation purposes.

Thesis (MA (Geography and Environmental Studies))--University of Stellenbosch, 2006. / The Okavango river along the panhandle of the Delta, in Botswana, is home to many wildlife species as well as to many large village communities. Local communities rely on the riverine system and its resources for subsistence and commerce. Activities associated with the utilization of these resources are governed by the fluctuating water levels of the river, which inhibit access during high water levels and allow access during low water levels. The high intensity of activities, such as reed harvesting, fishing and increased tourism, during low water periods coincides with the breeding season of many wildlife species in the system, including the Nile crocodile (Crocodylus niloticus). Over 90% of crocodile breeding areas in the Delta are found only in the panhandle region. The association between the intensity of human activities in the floodplains and crocodile nesting activity means that much of the habitat required for nesting is vulnerable to human disturbance and this could have severe negative impacts on the future of the Okavango crocodile population. The study evaluated habitat vulnerability by mapping and spatially comparing habitat suitability, based on optimum environmental requirements for crocodile nesting, and human disturbance factors. A detailed crocodile nesting survey was carried out to locate and test all nesting sites according to criteria selected by species experts. The results from the survey were used to locate suitable nesting habitat in the study area by analysis in a Geographic Information System (GIS). Disturbance factors were visually identified and their locations in the study area spatially mapped. Their spatial influences on crocodile nesting were used as factors in a Multi-Criteria Evaluation (MCE) that evaluated the combined effect of the disturbances on the area defined as suitable crocodile habitat. The results indicate the extent of habitat vulnerable to human disturbances. The results from the study show that 59% of once suitable crocodile habitat is currently disturbed by human activities. Most of the remaining 41% of undisturbed habitat is located along the Moremi/Phillipa side channel, which represents a core area for protection measures to be instated. The study recommends the declaration of a crocodile nesting sanctuary in this side channel to ensure the breeding success of this keystone species.

NOTE FROM THE LIBRARY: PLEASE CONTACT THE AUTHOR AT indisunflower@yahoo.com OR CONSULT THE LIBRARY FOR THE FULL TEXT OF THIS THESIS.... This thesis investigates the trajectory traced from Sarah Baartman, a Khoisan woman exploited in Europe during the nineteenth century, to a contemporary writing workshop with circumcised, immigrant West African women in Harlem New York by way of a selection of African women's memoirs. The selected African women's texts used in this work create a new testimony of speech, fragmenting a historically dominant Euro-American gaze on African women's bodies. The excerpts form a discursive space for reclaiming self and as well as a defiant challenge to Western porno-erotic voyeurism. The central premise of this thesis is that while investigating Eurocentric (a)historical narratives of Baartman, one finds an implicitly racist and sexist development of European language employed not solely with Baartman, but contemporaneously upon the bodies of Black women of Africa and its Diaspora, focusing predominantly on the "anomaly of their hypersexual" genitals. This particular language applied to the bodies of Black women extends into the discourse of Western feminist movements against African female circumcision in the 21st century. Nawal el Saadawi, Egyptian writer and activist and Aman, a Somali exile, write autobiographical texts which implode a western "silent/uninformed circumcised African woman" stereotype. It is through their documented life stories that these African women claim their bodies and articulate nationalist and cultural solidarity. This work shows that Western perceptions of Female Circumcision and African women will be juxtaposed with African women's perceptions of themselves. Ultimately, with the Nitiandika Writers Workshop in Harlem New York, the politicized outcome of the women who not only write their memoirs but claim a vibrant sexual (not mutilated or deficient) identity in partnership with their husbands, ask why Westerners are more interested in their genitals than how they are able to provide food, shelter and education for the their families, as immigrants to New York. The works of Saadawi, Aman and the Nitandika writers disrupt and ultimately destroy this trajectory of dehumanization through a direct movement from an assumed silence (about their bodies, their circumcisions and their status as women in Africa) to a directed, historically and culturally grounded "alter" speech of celebration and liberation. / English Studies / D.

This thesis examines the role of Melodi Ya Tshwane Christian Youth Ministry (MyT CYM) in the context of what is increasingly observable environmental crisis with a view of developing a contextual approach to ecological mission. The research does not focus primarily on the environmental crisis itself except to note that its scope incorporates not only environmental issues, but has some important implications for social justice as well. The research recognises the role that MyT CYM must play as part of their contribution towards addressing the environmental crisis. Such a role is based not on a pragmatic response to the situation, but flows from the missional nature and theology of the church. Therefore, the missional church has an obligation to address this issue, through Christian mission that takes seriously the biblical call to care and preserve the integrity of creation. Finally, this research aims to assist MyT CYM to understand the theological basis for contextual action towards developing an appropriate ecological mission. / Christian Spirituality, Church History and Missiology / M.

This thesis presents a history of the landscape of Nqabara, an administrative area in a rural and coastal area of the Eastern Cape Province, South Africa. In the process of investigating landscape history, the inquiry engages with a range of data sources from diverging discursive contexts, including data from ethnographic fieldwork, from the consultation of archival documents and historical reports as well as from comparative historic and ethnographic research, necessitating a critical consideration of the epistemological contexts of data production and the dialogue between researcher and data. Furthermore, in its aim to move beyond historical description towards explanation, the study interrogates the dualist ontological conceptualisations of nature and culture, society and ecology, object and meaning upon which are built three dominant conceptual frameworks concerned with human-environment relationships: social-ecological systems theory, transdisciplinary landscape studies and political ecology. Drawing primarily upon the works of James Gibson, Anthony Giddens and Tim Ingold, an ontological foundation is developed to guide the enquiry and move towards an alternative understanding of the relationship of people’s livelihoods with respect to the landscape in which it is lived, which I call here the praxisembodiment perspective. This ontology takes the situated patterns of action of a situated agent-in-its-environment as its point of departure and proceeds to develop a framework explaining how relations among the patterns of action of different agents-in-their-environment, emerge in structures that simultaneously enable and constrain future action. The foundation is thereby provided for a monist understanding of how landscape and social structure emerge simultaneously from the complex intersection of patterns of actions and interactions of agents in their environment. This framework calls for an understanding of time, space and scale, not as independent variables influencing process and action, but as emergent properties arising from the patterns of actions of situated agents. Finally the alternative ontology is applied to the history of landscape and livelihoods of people of Nqabara. It is concluded that an appropriate understanding and explanation of the critical transformations in the landscape as well as in social institutions, should be sought through analysis of the complex ways in which patterns of action of multiple spatial and temporal rhythms and between multiple agents in an environment, intersect and resonate.

La zone tropicale connaît à l’heure actuelle une réduction catastrophique de la superficie des écosystèmes forestiers qui jouent pourtant un rôle essentiel dans la régulation climatique et qui constituent un réservoir inestimable de la biodiversité. Les causes de cette déforestation sont multiples et complexes. Même si l’agriculture constitue l’une des causes majeures de la déforestation dans la plupart des régions tropicales, l’Afrique sub-saharienne a connu des influences exceptionnelles liées aux conflits sociaux qui ont entrainé un afflux massif de réfugiés ou de déplacés internes. Au Burundi, l’instabilité sociopolitique survenue en 1993 a entrainé un déplacement massif de la population constituée essentiellement d’agriculteurs. Une partie de cette population déplacée s’est réfugiée à l’extérieur du pays tandis qu’une autre s’est retrouvée dans des camps de déplacés à l’intérieur du pays. L’objectif de cette étude est de caractériser la dynamique spatio-temporelle de l’occupation du sol au sud et sud-est du Burundi en mettant un accent particulier sur l’influence de cette migration forcée de la population. La dynamique et la biodiversité végétale de la forêt de Bururi qui est située dans ce paysage anthropisé ont également été analysées. Sur la base de 6 images satellitaires et des observations sur le terrain, cette étude montre que le sud et sud-est du Burundi est caractérisé par une augmentation de l’anthropisation au fil du temps. L’impact négatif de l’instabilité sociopolitique sur la végétation naturelle a été mis en évidence par la diminution du degré d’anthropisation au fur et à mesure que la distance aux camps de déplacés augmente. Il est également confirmé par le fait que l’anthropisation de la zone située autour des camps est plus importante pour les années qui ont suivi le déclenchement de l’instabilité sociopolitique par rapport aux années antérieures. Ainsi, les résultats de cette étude ont permis de confirmer que les camps de déplacés ont significativement contribué à la dynamique de l’occupation du sol dans cette région. La création de nouvelles parcelles agricoles ainsi que la recherche du bois de chauffe autour des camps sont à l’origine de cette forte déforestation. Cette étude montre également que la distribution d’abondances des plantes de la forêt de Bururi est conforme à la distribution log série, ce qui constitue également un indicateur de sa perturbation malgré son statut d’aire protégée. L’agrégation de certaines de ses espèces arborescentes pourrait être l’une des conséquences de ces perturbations anthropiques. En outre, la prépondérance de certains arbustes pionniers généralement indicateurs des forêts tropicales africaines secondarisées, serait un indicateur d’une perturbation anthropique récente qui pourrait être attribuée à cette instabilité sociopolitique. La mise en place d’une politique nationale de réhabilitation des anciens emplacements des camps ainsi que la restauration des espèces menacées s’avèrent par conséquent indispensables./Nowadays, tropical zones are characterized by a catastrophic decline of forest ecosystems areas which play however an important role in climate regulation and biodiversity conservation. There are numerous and complex causes of deforestation. Even if agriculture is one of the main causes of deforestation in most tropical regions, sub-saharan Africa is known to have exceptional influences related to social conflicts that led to a massive flow of refugees or internal displaced population. In Burundi, socio-political instability which occurred in 1993 also led to massive waves of displaced people, essentially farmers. A part of them fled to foreign countries whereas others were kept gathered in camps throughout the country. The present study aims to analyze the land cover spatiotemporal dynamics in south and southeast of Burundi and is particularly focused on the influence of this population forced to migrate. Dynamics and plant diversity of Bururi forest located in this anthropogenic landscape were also investigated. The study combines six Landsat multispectral satellite images analysis with fielding observations. The study highlights an increase in natural vegetation disturbance by anthropogenic activities over time. The negative impact of socio-political instability has been demonstrated by an anthropization decrease when the distance from the camps increases. It is also confirmed by a high anthropogenic pressure in the camp’s surrounding zone during the period that followed the outbreak of the socio-political instability than in previous years. This result confirms that displaced population camps have significantly contributed to the land cover dynamic in the south and southeast of Burundi. Agricultural and domestic firewood collecting activities in camp’s surrounding zone are the main causes of deforestation during instability period. The observed plant species abundance distribution in Bururi forest was found similar to the log series model which also suggests the impact of disturbance on the plant abundance distribution despite the status of this ecosystem as protected area. The spatial aggregation of some of its tree species would be considered as a consequence of anthropogenic disturbance. In addition, the observed pioneer shrubs usually characteristics of secondary African tropical forests can be considered as anthropogenic recent disturbance indicators and would be attributed to the socio-political instability impact. This study recommends the establishment of a national rehabilitation policy of those disturbed zones around the camps and restoration of endangered plant species. / Doctorat en Sciences agronomiques et ingénierie biologique / info:eu-repo/semantics/nonPublished

Since human beings began to use and shape the land, their influence on their<p>environment has kept on growing so that little or no ecosystem in the world is now<p>considered as untouched. This induces pressures on ecosystem health and land scarcity.<p>Africa is of particular concern because it still presents broad undisturbed zones and<p>key ecosystem services, despite being submitted to increasing anthropogenic pressures.<p>Landscape ecology appears suitable for the study of such phenomena, thanks to its spacebased<p>integrative nature and geographical level of focus. It studies the impact of spatial<p>pattern transformation — especially heterogeneity and its components — on ecological<p>processes and provides powerful analytical tools of landscape anthropisation.<p>The main objective of this thesis is to organise the concepts and methods, from<p>landscape ecology and related disciplines, into a consistent logic, to pinpoint missing<p>analytical frameworks for response-oriented anthropisation assessment, and to apply them<p>to African cases to explore the spatial patterns of anthropisation. In order to address<p>landscape anthropisation, we assemble diverse disciplines into a logical network (DPSIR).<p>The new theoretical framework is tested on Lubumbashi (DRC). In order to address<p>spatial patterns, we first evaluate the thermodynamic connection of the term entropy in<p>landscape ecology: spatial heterogeneity, unpredictability and scale influence. Then, based<p>on 20 landscapes, we highlight the complex relationship between spatial heterogeneity<p>and landscape anthropisation. We finally use the modelled relationships to test the<p>anthropogenic origin of the spatial pattern of a land cover class in Lubumbashi.<p>The main results of this research show that several concepts are used to describe different<p>aspects of anthropisation and that its quantification strongly depends on the reference states.<p>Data formats can be combined into a new assessment method ensuring more precision<p>and comparability, but a good field knowledge is required. As for heterogeneity, the<p>existing definitions of landscape entropy follow the logic of thermodynamics or information<p>theory, that are not compatible. Only unpredictability could be properly interpreted in<p>thermodynamic terms if energy transfer measurements were performed at the appropriate<p>level. The anthropogenic effects on heterogeneity completely diverge depending on the<p>amount of already anthropised surface, on the land cover type (natural or anthropogenic),<p>and on the heterogeneity components.<p>The aforementioned findings could be adapted to include functional aspects and<p>better address the relationship between spatial pattern and ecological processes. Such<p>integration would help designing response actions that can recommend human activities<p>and spatial patterns that could optimise the use of land to ensure ecological functioning<p>while supporting human development. / <p>L’influence croissante de l’homme sur son environnement affecte désormais le monde<p>entier, ce qui induit des pressions sur la santé des écosystèmes et raréfie les ressources<p>en terres.

Ensuite, le lien entre la thermodynamique et l’utilisation du terme entropie en<p>écologie du paysage est examiné. Vingt paysages servent alors à mettre en évidence la<p>complexité de l’impact de l’anthropisation sur l’hétérogénéité du paysage. Enfin, cette<p>modélisation sert à mettre en évidence l’origine anthropique de la structure spatiale d’une<p>classe d’occupation du sol à Lubumbashi.<p>Les résultats principaux de cette recherche sont que pléthore de termes sont utilisés<p>pour représenter différents aspects de l’anthropisation et que sa quantification dépend de<p>la définition d’états de référence. Cependant, la combinaison de différents formats de<p>données peut aboutir à une nouvelle méthodologie plus précise et adaptable, mais cela<p>nécessite une bonne connaissance de terrain.

Les travaux de recherche ont été menés dans la réserve de biosphère de la boucle du Baoulé (RBBB) au Mali. Cette réserve est constituée de 3 aires, Badinko, Kongosambougou et Fina. Cette étude a été faite dans l’aire de Fina, la plus importante pour sa richesse en faune. La péjoration des conditions climatiques et les impacts des pressions anthropiques croissantes ont entraîné une dégradation des écosystèmes en particulier la biodiversité végétale. L’objectif de notre recherche est d’étudier l’influence des gradients anthropique et géomorphologique sur la variation de la biodiversité végétale dans la RBBB. Elle contribuera à la caractérisation et à l’évaluation de l’état actuel de la végétation dans une perspective de conservation durable des ressources végétales en particulier la biodiversité. Nous sommes partis de l’idée que les aires protégées constituent des espaces témoins de conservation des milieux naturels qui, comparés aux milieux perturbés permettraient de caractériser l’état d’évolution de la biodiversité végétale. Deux approches ont été utilisées pour aborder cette étude :l’approche synchronique et l’approche diachronique. Un recensement et une classification des espèces ont été effectués en s’appuyant sur le dispositif de zonage d’une réserve de biosphère basée sur les degrés de pression (régimes de protection) et la situation géomorphologique. Puis une quantification des variations de pressions liées aux activités anthropiques a été faite. <p>Nos résultats ont montré que les facteurs structurants de la végétation varient suivant la géomorphologie et surtout le dispositif de zonage (gradient anthropique). C’est dans les milieux perturbés que la diversité est élevée, mais avec un niveau d’organisation peu homogène comparativement aux milieux non perturbés. L’intensification actuelle des pressions dans les milieux perturbés et la dégradation des formations végétales qui en résulte n’entraînent pas actuellement dans la réserve une baisse de diversité. Aussi, dans les conditions écologiques locales pratiquement semblables dans la réserve, le zonage caractérisant les niveaux d’anthropisation est autant important que les facteurs texture du sol qui sont liés aux conditions géomorphologiques dans la structuration floristique. Les résultats phytosociologiques ont montré l’individualisation de 10 groupements végétaux dont 6 en milieux perturbés avec une tendance à la dégradation de la végétation et sa transformation en savane arbustive et 4 en milieux non perturbés marqués par la disparition des formes de végétation originelles. La plus forte densité en espèces est observée dans les groupements végétaux des unités de plaine et de vallée pour l’ensemble des 3 zones. C’est dans ces unités également que la surface terrière pour les arbres de plus de 8 m et la valeur pastorale sont importantes. La diminution du recouvrement des espèces herbacées de bonne valeur fourragère en particulier les pérennes est corrélée aux perturbations liées aux intenses activités anthropiques (agricole et pastorale par exemple). Ces activités engendrent la dégradation du milieu, une baisse de la valeur pastorale qui est indépendante de la biodiversité. Les dynamiques temporelles de la composition du paysage forestier de la réserve ont montré une ouverture du paysage caractérisée par une extension des superficies cultivables de la zone de transition vers la zone protégée ainsi que la réduction de la superficie des savanes arborées et la transformation progressive du paysage en savane arbustive. L’étude a permis de comprendre que le dispositif législatif classique de protection ne correspond pas à la réalité de terrain. De façon générale, l’influence des gradients géomorphologique et surtout anthropique est perceptible sur la structure de la flore et de sa diversité. <p>Une extension de notre approche d’étude dans les réserves de Badinko et de Kongosambougou permettra d’asseoir un dispositif de suivi de l’évolution spatio-temporelle de la végétation et de poser les bases d’une politique rationnelle de conservation de la réserve de biosphère de la boucle du Baoulé.<p><p>Mots clés :Anthropisation, diversité floristique, dynamique spatiale, géomorphologie, réserve de Fina, Mali.<p><p>ABSTRACT<p>The research was conducted in the Fina, part of biosphere reserve of « boucle du Baoulé » (RBBB) in Mali. This reserve consists of 3 areas, Badinko, Kongosambougou and Fina. Fina area is the most important for its rich fauna, this study was done. The climatic conditions pejoration and the impacts of increasing human pressures have led to ecosystem degradation, particularly plant biodiversity of the Fina reserve. In this study we have updated data on plant diversity and its variation based on the device of biosphere reserve zoning based on the pressure degree (protects systems). The objective of this thesis was to test the main hypothesis that protected areas are witness spaces of natural settings conservation that, compared to the disturbed areas, would characterize plant biodiversity evolution. Two approaches were used to address this study: synchronic and diachronic approach. Our results showed that the vegetation structural factors vary with the environment (zones) and geomorphology. The correlations between vegetation and ecological factors showed that the disturbance gradient is a major factor in the floristic variability. Human pressure intensification in disturbed habitats and resulting vegetation degradation do not currently induce any decrease of diversity in the reserve. In local similar environmental conditions as is the Fina reserve case, zoning characterizing the human impact levels is as important as the soil texture factors that are related to geomorphological conditions in the floristic structure. The phytosociological results showed the individualization of 10 plant groups in disturbed habitats, including 6 with a tendency to shrubby savanna and 4 in undisturbed environments marked by the disappearance of the vegetation original forms. The highest density of species is observed in plant communities of the plain and valley units in all the three zones. It is also in these units that basal area for trees over 8 m and pastoral value are important. The herbaceous species of good fodder value recovery reduction in particular the perennial causes the environmental degradation, and the pastoral value reduction that is independent of biodiversity. Temporal dynamics of the forest landscape composition of the reserve showed an opening of the landscape characterized by an expansion of arable land in the transition zone to the protected area of the reserve, the decrease in savanna area and gradual transformation landscape in shrubby savanna.<p>An extension of our study approach in the Badinko and Kongosambougou reserves could help establishing a monitoring of the spatial and temporal vegetation evolution and putting the rational politics bases of Baoulé biosphere reserve conservation.<p><p>Key words: Anthropisation, geomorphology, floristic diversity, Fina reserve, spatial dynamics, Mali.<p><p> / Doctorat en Sciences agronomiques et ingénierie biologique / info:eu-repo/semantics/nonPublished
