The role of Venda culture in nature conservation : a case study of the inhabitants of the Tshivhase area

Khorommbi, Konanani Christopher January 2001 (has links)
This thesis investigates the role of Venda culture in nature conservation and natural resource management. The project is based on the premise that the survival of human beings is entirely dependent on the extent to which different cultures conserve the natural environment. The researcher assumes that the scientific approach is not the only one that is capable of addressing environmental issues but that indigenous technology has a positive role to play. The study specifically looks at the relationship between the Venda culture and conservation of land, water, plants and animals. In order to achieve this goal, the study was divided into five chapters. The introductory chapter includes the statement of problem, delimitations of the study, the definitions of concepts, the assumptions, and the significance of the study. The literature review provides an overview of the indigenous strategies of nature conservation and natural resource management from a broader international approach to a specifically Venda approach. The researcher looked at the cultural perspective of the four areas under investigation. This chapter is followed by themethodological justification that discusses the social survey as a researchmethod for carrying out this study. The results presented in the fourth chapter comprise raw data from the three sectors of respondents, namely traditional leaders, traditional healers and villagers. Under each item, common responses have been grouped together for presentation and specific responses for the three sectors were presented independently from one another. This has provided the researcher with the opportunity to identify areas of similarities and differences among the three sectors. Both complementary and conflicting ideas are summarised and used as a basis for analysis. The results reflect a high degree of agreement among respondents. The discussion in chapter five was based on the results and relevant literature. The researcher’s approach was to depict the most common views among the three sectors and their conservation implications. In the discussion, the strengths and weaknesses of the Venda cultural approach were exposed in relation to the five sub-problems under investigation. The recognition of the Venda indigenous technology of natural resource management has been proposed because of its importance in nature conservation. In the recommendations the formulation of policy that overlooks local values was criticised. The use of the Venda approach as a basis for the development of conservation projects was strongly recommended. Lastly, itwas proposed that further investigations of specific aspects of the Venda cultural be considered for possible incorporation in future management of the natural environment.

Towards knowing through doing : improving the societal relevance of systematic conservation assessments

Knight, Andrew Thomas January 2007 (has links)
Systematic conservation assessments are spatially-explicit techniques for prioritising areas for the implementation of conservation action. There has been considerable reference in the peer-reviewed literature as to the usefulness of these tools, which appear to be primarily used by academics for theoretical research. A literature review and author survey reveals the peer-reviewed literature is largely theoretical, although conservation action results more frequently than reported. The effectiveness of these interventions is generally described as only ‘fairly effective’. This general trend, coupled with previous personal failures in translating systematic conservation assessments into effective conservation action triggered an explicit process of social learning implemented as action research. It examined the workings of the Subtropical Thicket Ecosystem Planning (STEP) project, which included development of a systematic conservation assessment. Systematic conservations assessments simply provide information on where action should be implemented, and so are only useful if situated within broader operational models for conservation planning. Most operational models presented in the peer-reviewed literature are primarily focused upon the testing ecological data, not upon the delivery of conservation action. A new operational model for conservation planning is presented which more accurately reflects the ‘real-world’ process of conservation planning. An implementation strategy is an essential complement to a systematic conservation assessment. It describes how specific, explicitly-stated goals will be achieved, who is accountable for undertaking these activities, and the resources required. As the Implementation Specialist for the STEP Project, I co-lead the collaborative development of an implementation strategy with stakeholders that aimed to mobilise resources towards achieving common goals. Whilst the development and initial uptake of the strategy was good, subsequent implementation has flounder. The reasons for this are explored. The ultimate pragmatic goal of a conservation planning process is the establishment of effective social learning institutions. These develop common visions, mobilise collective action, and adaptively learn and refine their conservation activities. Thicket Forum is one xi such institution established through the STEP Project. My involvement with Thicket Forum since 2004 in implementing an adaptive learning approach facilitates collaboration between land managers, government and research organisations. Systematic conservation assessments evolved in response to the ad hoc way in which protected areas were implemented, leaving unrepresentative, biased protected area networks. Most research is theoretical and without an intimate understanding of the social-ecological system of a planning region, notably opportunities and constraints for implementing conservation action. Highlighting the importance of an approach which is flexible, not only in space, but in time, which can capitalise upon implementation opportunities, is important for stemming the myth that opportunism is the nemesis of systematic conservation assessments. To this end, conservation planners have been slow to include factors influencing effective implementation in systematic conservation assessments. Many studies which identify candidate protected area networks, first, fail to identify the specific instrument(s) to be applied, and second, assume all intact land is available. Having mapped the willingness of land managers in the Albany District, South Africa, to sell their land, it is demonstrated the majority of targets fail to be achieved because land managers will not sell. Knowing this, the current focus of gathering ever-more ecological data is misplaced. Human, social and economic factors influence target achievement, efficiency and spatial configuration of priority areas. Selecting important areas for conservation, particularly at the local-scale, requires the mapping of factors which define opportunities for conservation. Land manager willingness to collaborate and participate, entrepreneurial orientation, conservation knowledge, social capital, and local champions were applied using a method of hierarchical clustering to identify land managers who represent conservation opportunities for private land conservation initiatives.

The self-actualisation of the black Natal Parks Board employee

Melrose, Andrew Denis. January 1999 (has links)
Submitted to the Faculty of Education in fulfillment of the requirements for the Master of Education in the Department of Educational Psychology and Special Education at the University of Zululand, South Africa, 1999. / In essence The study revolved around the following: • The level of illiteracy of black Natal Parks Board employees. • . actors which contribute to the level of illiteracy of Natal Parks Board employees. • To determine in the light of the findings obtained, certain guidelines towards the route to be followed by illiterates and semi-illiterates, in attaining a state of literacy. The research was specifically directed at the problems confronting adult illiterates and semi-illiterates in their striving for literacy. Both the factors influencing educational progress and the best route to be taken to attain to literacy were studied. For the purpose of the empirical investigation a self-structured questionnaire was utilised. The respondents were selected at random from rural areas throughout KZN, from the learners from seven classes who have graduated from the basic Zulu, advanced Zulu and basic English classes and from people who are still awaiting incorporation into the adult literacy programme. A summary was presented and based on the findings of this study, the following recommendations were made: • Although there is already an ABET system and a bursary scheme currently operating in the NPB, it is nevertheless recommended that the NPB and other like-organisations should: reprioritise their goals from conservation of species to the development of staff, draw up clear education policies, identify current educational levels, all skills training courses should comply with the National Qualification Framework and that the individual's current knowledge, skills and experience should be recognised and certificated. • In order to fully update staff on educational and training possibilities in the NPB and other similar organisations it is recommended that employees should have a say in educational and skills training and courses should be regularly advertised throughout the organisation and education and training needs should be discussed with individual staff members. In a climate where the employer realises and accepts his obligations, the organisation's budget should reflect that education and skills training have a very high priority rating.

The watchers of the woods architecture for the conservation of South Africa's wildlife

Hunt, Miranda January 2019 (has links)
This document is submitted in partial fulfillment for the degree: Master of Architecture (Professional) at the University of the Witwatersrand, Johannesburg, South Africa, 2018 / Through increased urbanisation and industrialisation, the human species has become separated from the natural world, valuing the environment only as far as it is useful to us. Society has become used to living through a human-centric view that places humans above all other natural beings. The destructive nature of this perspective is visible to us in the rapid depletion of our natural resources and, perhaps most alarmingly, the increasing amount of species driven to extinction and endangerment by the destruction of natural habitats. As we are now beginning to see the harmful effect this view has had on the natural world, it is necessary for society to change the way we interact with the natural world. We need to begin to act not only for the good of ourselves, but with the good of all living beings in mind. A shift in perspective is needed that places the human species into the natural world as an equal part of the system rather than a being of superior importance. In order to achieve this shift, we must understand our role as an integrated part of our surrounding natural ecosystems. The Hluhluwe-iMfolozi Centre for Conservation is proposed as a centre devoted to conservation biology research placed within the Hluhluwe-iMfolozi National Park in order to promote the easy access of researchers, South African and international, to this rich natural ecosystem. Its aim is to enable researchers to make use of the unique opportunities this protected environment offers in understanding the rise and fall of plant and animal species and thus to further understand how to increase and protect the biodiversity of this country. As well as this, the Centre for Conservation aims to showcase a method of building that is in no way harmful to the surrounding sensitive landscape and that functions as a part of the ecosystem, thus displaying to visitors how humans can interact with their natural environment in a symbiotic relationship and promoting a deeper care and respect for the natural world / MT 2019

Integrating ecosystem services into conservation planning in South Africa

Egoh, Benis Nchine 03 1900 (has links)
Thesis (PhD (Botany and Zoology))—University of Stellenbosch, 2009. / Natural ecosystems provide many services that are crucial for sustainability and health of human society. Ecosystem services are the benefits people obtain from ecosystems (i.e. goods and services) and can be classified into provisioning (e.g. fibre, fuel wood); regulating (e.g. water and climate regulation); supporting (e.g. soil retention) and cultural (e.g. aesthetic value). The growing global human population and other threats place enormous stress on the natural environment reducing its capability to provide services. According to the Millennium Ecosystem Assessment, more than 60% of ecosystem services worldwide are being degraded or used unsustainably. The need to safeguard ecosystem services is therefore urgent. Biodiversity underpins most ecosystem services, but the functional relationship between biodiversity and services is not well known. A wide range of strategies exist for safeguarding biodiversity, but no such approaches have been developed for ecosystem services. A key conservation strategy is the use of systematic conservation planning to identify priority areas where effort should be focused. There are calls for the inclusion of ecosystem services into conservation planning geared towards biodiversity. Ecosystem services have been used for many years as an additional rationale to justify biodiversity conservation and it is often assumed that conserving biodiversity will also conserve services. However, it is unclear how different facets of biodiversity relate to different services and to what extent conserving biodiversity will safeguard services. This thesis addresses a range of issues relating to the integration of ecosystem services into conservation planning in South Africa. I first investigated the status of ecosystem services in conservation planning worldwide by reviewing the conservation planning literature from 1998 to 2005. Ecosystem services are clearly not adequately addressed in conservation assessments. A critical barrier preventing the inclusion of ecosystem services in conservation plans is the lack of spatially-explicit data. I developed a methodology for mapping ecosystem services in South Africa and mapped the distribution of five important ecosystem services (surface water supply, water flow regulation, carbon storage, soil retention and accumulation). Using the five services to examine relationships within services and between biodiversity revealed a lack of congruence between services and different levels of congruence with biodiversity features. However, including ecosystem services in a biodiversity assessment captured at least thirty percent of each of three services selected for the study. Nevertheless, a biodiversity plan may not necessarily capture adequate amounts of ecosystem services. Ecosystem services should be planned for explicitly instead of relying on biodiversity data. I identified priorities that met targets for five services in the grasslands of South Africa. This thesis provides new insights on planning for biodiversity and ecosystem services. The results have immediate applicability for conservation planning in South Africa. Keywords: Conservation planning, conservation assessments, ecosystem functions, ecosystem processes, ecosystem services, natural capital, biodiversity, soil, water, carbon.

Towards an understanding of plant rarity in Kwazulu-Natal, South Africa

Church, Brigitte 31 July 2014 (has links)
A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2014. / The persistence of rare plants is an important dimension in the conservation of biodiversity. Consequently an improved understanding of the nature and determinants of plant rarity and its relation with vulnerability to extinction could provide a basis for “proactive conservation” instead of the present day tendency for conservation actions to be “reactive”. In this dissertation I explore the relation between plant rarity and anthropogenic pressures (land transformation and use), biophysical factors, and plant traits in KwaZulu-Natal Province. Rarity was defined as the product of plant species abundance (population size) and its distribution (extent of occurrence). A number of a priori hypotheses regarding plant rarity were developed from the literature and these were then tested on a sample of plant species from KwaZulu-Natal. Species were selected in a stratified random manner to include species from different levels of threat and rarity or commonness. As the interest of this study was KwaZulu-Natal, only KwaZulu-Natal records were used for the analysis. Although the study suffered from a paucity of data particularly on the biological traits and behaviour of each species I was able to explore rarity in terms of seed dispersal distance, stress tolerance, habitat specificity and ecological niche width. I also explored potential island effects based on a species affinity to isolated erosional land surfaces and the anthropogenic effects of utilization and land transformation. To get an initial insight into relations, rarity was compared with each explanatory variable independently prior to using a multiple regression analysis approach aimed at understanding the potential interactive effects of suitable variables on rarity. Three different analytical techniques were used to provide a more robust understanding of the variable associations. These included Regression tree analysis (CART Salford Systems Inc., USA) and two generalized linear regression approaches; Generalized Linear Modelling (GLM) and Generalized Additive Modelling (GAM). All three multiple regression methods indicated that niche width had the strongest influence on rarity. Although Land Surface was shown to be the second strongest variable this, according to the GLM and GAM analyses, was due to a positive correlation between species with no affinity to land surface and species commonness. Visual representation of the regression tree analysis showed inconsistent partitioning of this variable throughout the tree indicating that land surfaces are not good predictors of rarity. Although the relation between Rarity Index and Habitat Transformation is not linear it was shown to be significant (p <0.1(p=0.0549)) after “smoothing” in GAM analysis. A smoothing curve on the bivariate analysis and the regression tree analysis indicated that species start to become rare after approximately 36% of their habitat is transformed. While GLM and GAM showed little or no relation between life history, dispersal distance, habitat specificity and rarity, the regression tree selected habitat specificity as the third most important splitter in the tree and dispersal distance was selected as a primary splitter for species with a niche width of greater than four. These differences observed in the three multiple regression analyses highlight the value of using more than one method to explore relations in ecological data. Considering all three analyses Niche Width is the strongest determinant of Rarity in KwaZulu-Natal, followed by Habitat Transformation and then Habitat Specificity. This improved understanding of the determinants of rarity will enhance our ability to prioritise plant species for conservation action. Key Words: ecological niche width, habitat specificity, habitat transformation, rarity, seed dispersal distance, stress tolerance, human use.

The challenge of applying systematic conservation planning to the marine environment using expert knowledge (focus: Sparidae)

Bause, Mariëtte January 2004 (has links)
Although the marine environment has generally been considered to be less in need of attention from conservationists, politicians and managers than the terrestrial environment, there has been an increasing appreciation that there is little left in the marine environment that can be considered unaltered by humans. Conservation action is therefore urgently needed to protect marine populations, species and environments from anthropogenic pressures. Since overharvesting seems to be the main cause of the collapse in coastal ecosystems, areas need to be protected so that stocks can recover. However, the proclamation of such marine protected areas (MPAs) need to be well planned to ensure that species are well represented and that their biological requirements are met in the long term. While terrestrial conservation planners have started to incorporate biological, social and economic information into so-called systematic conservation plans, marine planners have been more hesitant to use these approaches due to the greater openness of the ocean (with the associated greater dispersal of marine organisms and propogules, lower levels of endemism, and lack of ownership) and the paucity of available information. The current study aimed to investigate the applicability of systematic approaches to the process of selecting sites for a network of potential replenishment zones for seabream species that could supplement protection already afforded by existing no-fishing reserves. Since many of these seabream species are popular targets in both the recreational and commercial linefishery sectors, they have been overexploited and are in need of additional protection. Information on these species and the diversity of their associated reefs were obtained through consultations with scientists, managers and resource-users (namely SCUBA divers, spearfishers as well as recreational and commercial fishers). These data were obtained during workshops where Participatory Rural Appraisal (PRA) scoring and mapping methods were applied. Although ordinal-scale, rather than interval-or ratio-scale data were obtained, these data could be used in an interactive selection process. Because these methods require relatively cheap materials and few personnel, they could be used to collect information where limited budgets are available. Quantitative targets for the protection of individual species were set on the basis of their status in the Marine Living Resource Act, since this reflected their different requirements for protection. A preliminary investigation indicated that the current no-fishing reserves effectively achieved most of these goals for seabream species. The selection of sites for the replenishment network was based on irreplaceability analyses, while decisions between sites with lower irreplaceability values were based on explicit design rules. A total of 26 sites were required to achieve targets for all species. These replenishment zones could potentially be established, managed and monitored by voluntary community groups. This study therefore indicated that systematic conservation planning can successfully be applied to the marine environment, while the involvement of stakeholders is crucial to ensure that conservation action is supported.

An examination of the facilitatory role for environmental education of conservancies

Law-Jackson, Danielle January 2000 (has links)
This study examines the possibilities within the conservancy movement for the facilitation of environmental education. By means of a case study approach, a conservancy in the Northern Cape and the conservancy movement within the Free State provinces are compared with a view to elucidating factors militating against and promoting the success of environmental education programmes. The current lack of research in isolated rural areas is discussed. Re-orientation of perspectives regarding the value of conservancy-based environmental education within governmental, academic and local circles is recommended.
