An investigation into the development of environmental education as a field of practice in South African National Parks

Taljaard, Sandra January 2009 (has links)
This study looks at aspects of the development of environmental education in South African National Parks (SANParks), in relation to the emergence of national and organisational policy frameworks. In order to put current environmental education practices into context, the study firstly looks at the historical development line of environmental education in SANParks, as well as in the broader national context. This provides a framework within which the processes of change and development can be traced in terms of social, political and economic influences on an international and national front. The study finds that the promulgation of legislation, including the Constitution, National Acts and various other policies, reflected the trends of thinking and set the pace in a democratic South Africa, which led to the emergence of more explicit processes and refined policies. Popkewitz’s finding, that education emerged in modernity, is used in the study to illustrate this tendency. It finds that these changes in South Africa resulted in the establishment of more structured environmental education processes within SANParks, and led to the expansion, diversification and strengthening of environmental education as a field of practice over time. The study traces significant processes of recontextualisation of international and national environmental education related policies according to the framework established by Bernstein (1980). These processes of recontextualisation were followed in the formulation processes of SANParks policy and strategy documents in the period from 1999 to 2005, and resulted in an official pedagogic discourse for environmental education in SANParks. The study establishes a second level of recontextualisation, that is, the official pedagogic discourse of environmental education in SANParks is recontextualised to a pedagogic discourse of reproduction. The pedagogic discourse of reproduction relates to park practices, where contextualisation within park-based programmes appears to be strong. The park-based programmes resemble a ‘curriculum in practice’, which brings us to Cornbleth’s critical curriculum approach. The study utilises this approach to explore and explain the meaning of the critical perspective taken on curriculum construction and change efforts at park implementation level (Cornbleth, 1990). The study finds that the contextualisation of park programmes and practices lead to variety in park programmes, which adds richness to environmental education programmes and activities, and further highlights the fact that environmental education practices are prolific in national parks. The study also finds that historical and contextual processes associated with specific parks strongly characterise environmental education programmes and practices in those parks, and that partnership programmes, such as the Kids in Parks programme, contribute towards, and enhance the growth of environmental education as a specialised field of practice in SANParks. The study comments on the need for environmental education practices in SANParks to be reviewed and expanded in line with the contemporary approach towards the environment as a social construct of interacting components. These components include the biophysical, social, economic and political dimensions. The study also highlights the need for the recognition and acknowledgement of the long, historical development line of environmental education in SANParks in order to build on established structures in a holistic way. The study further determines a need for strong leadership to successfully expand this specialised field of practice and encourages a participatory approach in the review and further development of this field of practice in SANParks. The study ultimately finds that environmental education in SANParks has a long and rich development profile, which has placed it in a strong position for further development. However, it concludes that there is a great need for a rejuvenated approach, which requires expert knowledge, professionalism and broad based networking approach to enable meaningful expansion within this specialised field of practice.

A critical investigation of conservation attitudes of the local community living adjacent to Akagera National Park, Rwanda

Ngabonziza, Gaetan January 2010 (has links)
Thesis (MTech (Tourism and Hospitality Management))--Cape Peninsula University of Technology, 2010 / Over the past years, protected areas have been affected by illegal activities, which are perpetrated by humans and continuations of these activities do not only harm wildlife, but also the welfare of current, as well as, future generations. Conservation of wildlife cannot be achieved if local community support is not ensured. This study aims to find whether or not improved or positive relationships between protected area and people can effect long-term conservation of wildlife. The main objectives of the study were to investigate conservation attitudes of the Rwandan community that lives adjacent to the Akagera National Park. A quantitative survey-based study, which used a self-administered structured and closeended questionnaire, was undertaken within a period of a month and a half to obtain information about conservation attitudes within the local community. In addition, qualitative data was gathered through in-person unstructured interviews with key informants including local authorities and park officials in order to verify and enrich quantitative data, which was obtained from the survey. Collected data was analysed with use of the Statistical Package for Social Science (SPSS) for descriptive statistics in the form of tables and charts. In addition, statistical tests, using chi-square values at the 0.05 level of significance, were conducted to determine which factors influence the local community’s conservation attitudes. The study revealed that the local community support Akagera National Park’s conservation although they participate in illegal activities within the park. Poaching and livestock grazing are the main illegal activities that take place at Akagera National Park. The study also found that people’s awareness of wildlife importance does not necessarily translate into positive attitudes towards conservation. Problems caused by wildlife, combined with the absence of economic opportunities from the protected areas, are strong influencing factors regarding the local community’s conservation attitudes. The findings of this study suggest that the local community’s support for conservation can only be achieved if problems that are caused by wildlife are effectively addressed and solved and people are provided with more economic opportunities, which would allow them to improve their welfare.

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 approach to integrated ecosystem planning: an evaluation of the Minnewanka area plan, Banff National Park

Haid, Susan B 11 1900 (has links)
The Lake Minnewanka area is one of Banff National Park's most scenic and highly visited regions. Impacts such as the loss of significant montane habitat (characteristic of the Lower Bow Valley ecosystem) and social implications like crowding led to the need to develop a strategy for managing the area. The author worked with a planning team from the Canadian Parks Service(CPS) in Banff National Park (BNP) to develop the Minnewanka Area Plan. The primary purpose of the thesis is to evaluate the Minnewanka Area Plan to determine whether it effectively serves to maintain and enhance ecological integrity. A theoretical framework based on integrated ecosystem management was developed to evaluate the plan. Normative criteria from literature on recreational carrying capacity management and meaningful public participation were defined and applied to the plan. Overall, the plan was rated as successful according to the normative criteria. All of the criteria for an effective approach to carrying capacity management were considered and the plan reflected a fair and efficient public participation process. Stakeholder input influenced plan decisions to a high degree and several partnerships were developed through the planning process. Several inadequacies in the plan were identified through the evaluation. The adoption of an approach to ecosystem management called the Limits of Acceptable Change (LAC) was recommended as a guiding principle within the plan. The step-by-step LAC model was seen as overly complex in the context of the case study. Indicators and a monitoring program which are central to the LAC process were not defined as part of the plan. The evaluation of the public participation process indicated that stakeholder participation was high early in the planning process and reflected a partnership relationship where stakeholders shared the power of decision-making. During completion of the draft and final plan, the process became one of public consultation where the level and frequency of participation was lowered. Recommendations for improving the efficacy of the Minnewanka Area Plan are made within the thesis. A simpler approach to visitor and resource management which maintains the essential criteria of the LAC approach is suggested. Measures for maintaining a high level of public participation and improving the accountability of the CPS in decision-making are proposed. The normative criteria based on carrying capacity management and meaningful public participation processes are presented as a model for facilitating integrated ecosystem management in area planning within national parks. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Mining in parks : an analysis of the policy framework for B.C.'s provincial parks

Wilson, Norma J. January 1989 (has links)
The provincial parks of British Columbia have endured varying degress of resource exploitation since the creation of the first provincial park in B.C., Strathcona Park in 1911. B.C. Parks, the government agency which manages B.C.'s parks, administers the Park Act (R.S.B.C. 1979 C.309) and derives its dual goals for recreation and conservation from the Act. In addition to the Park Act, there are several levels of policy for B.C. Parks which guide decisions regarding resource use in parks, including "Striking the Balance - B.C. Parks Policy Statement," occasional policy statements in News Releases, and some conditions in resource use permits. This thesis examines the levels of policy which guide decisions regarding mining in parks in British Columbia and the consistency of the commitment to the goals of B.C. Parks through the policy levels. The approach to policy analysis taken is that a policy is both an output of the level above, and an input to the level below. Three criteria are derived from the definitions of policy in the literature. They are that policy should be clear and a guide to decision-making, that it should be forward-looking, and that it should be enforceable. The fourth criterion says that the goals of B.C. Parks stated in the Park Act should be traceable through the policy levels. Since 1973, there have been five policies regarding mining in B.C.'s parks which stand out as significantly altering the commitment of B.C. Parks to its goals. In two of these policies the recreation and conservation goals of B.C. Parks are apparent, while the goals are not apparent in three of the policies. Foreseeable decisions for mining in parks are examined, and the ability of the present policies to guide the decisions is tested. B.C. Parks retains little decision-making authority with respect to mining in parks. On a mineral claim in a recreation area, the Ministry of Energy, Mines and Petroleum Resources has jurisdiction. Off a mineral claim in a recreation area, B.C. Parks has limited authority over mining activities. The fundamental decisions which rests with B.C. Parks is whether or not the recreational values of the area are sufficiently impaired by mining to delete it from the park system. Surprises can occur when the results are different from what was expected, either because the cause is different, the behaviours are not what was anticipated, or an action produces the opposite result from what was intended (Holling 1986: p.294). Several surprises with regard to mining in Parks are imagined and the challenge to the goals of B.C. Parks through the policy levels is examined. A strong commitment to the goals at the upper levels of parks policy, and reflected through the levels is proposed to ensure that B.C.'s parks survive challenges from mining and from other sources. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

A resource and visitor inventory of Yoho Valley, Yoho National Park, British Columbia

Vold, Terje January 1976 (has links)
The study objective was to inventory natural resources, use patterns, and visitor characteristics in Yoho Valley, Yoho National Park, British Columbia, and to offer some management considerations for the area. In the natural resource inventory, research emphasis was placed on a soil and landform survey which resulted in a soils map of Yoho Valley. Soil map units are discussed in detail, and interpretations are developed on the suitability of soil types to support trail and campground users. Soil map unit descriptions include information on soil parent material, horizonation, depth, texture, coarse fragments, drainage, slope, elevation range, and associated vegetation. The soils of Yoho Valley were divided, into 13 soil map units consisting of 6 different landforms and 5 separate soil orders. Humo-Ferric. Podzols occurred in the Engelmann spruce - subalpine fir forest zone oh morainal landform material. Degraded Eutric Brunisols were found on relatively stable colluvial material and glacio-fluvial deposits in the same forest zone. Alpine Eutric Brunisols occurred on both till and colluvium in the alpine zone above 7200 feet elevation. Cumulic and Orthic Regosols occurred on both steep colluvium and.on relatively flat fluvial deposits. Small amounts of Organics and Gleysolics were also found in the study area. Steep slopes were found to be the major soil limitation for both trails and campgrounds; over 90% of the study area occurs on greater than 30% slopes, and nearly 60% of the valley is on greater than 60% slopes. Information related to the climate, geology, flora, and fauna of the study area was examined as background. Photographs were systematically taken along trails to document visual conditions of trail sides. A visitor survey was undertaken to assess the amounts and distribution of road, campground, and backcountry use. Traffic counter recording devices were installed on the Yoho Valley road and calibrated to determine visitor-days of road use. The Takakkaw Falls campground in Yoho Valley was visited each day in 1972 to determine camper-nights of use. Rates of registration were calculated for the trail kiosk for backcountry use estimates. Use data were compared, over time to determine growth trends. It was estimated that approximately 71,300 visitors entered Yoho Valley by road in 1974. Approximately 79% of the visitors were day users, while 21% were overnight users. Road use increased at the average annual rate of 10% since 1969. Campground use in 1974 was 6,075 campers % use increased 20 to 25% per year from 1968 to 1972 until use restriction measures were implemented in 1973. An estimated 8,40.0 visitors hiked in the valley's backcountry in 1974. Approximately 74% of these visitors were day hikers. Backcountry use has increased at the average rate of 20% per year since 1965. A road and backcountry survey of visitor characteristics was conducted in 1972 by employing on-site personal interviews. Two hundred parties were interviewed on the Yoho Valley road and 193 parties were sampled on backcountry trails. The survey questionnaire provided information on the demographic characteristics, trip characteristics, preferences and opinions of the study area , users. The results are discussed and compared with other related research. Yoho Valley users were found to have disproportionately more income and more formal education than the Canadian population. Users were also more likely to have a 'professional' occupation and to reside in a large city. Backcountry users, relative to road users, were more likely to be male, to be between 10 to 39 years old, to have less income, to have more education, to be a 'professional', to be from a large city, and to be Canadian and Albertan. The median distance traveled by road users from their place of residence was 2000 miles, while it was half that or 1000 miles for back-country users. Most road users spent less than two hours in the study area, while hikers usually spent between five to twelve hours in the area. Questions related to visitor preference indicated a fairly high level of satisfaction by both visitor groups. Over two-thirds of the valley's road users and nearly one-half of the backcountry users said there was 'nothing at all' that they disliked about their visit. Most visitors actually preferred the valley's present gravel road to a paved road. Seventy-five percent of the valley's road users and 89% of the backcountry users opposed the idea of paving the Yoho Valley road. Most visitors were concerned that paving the road would lead to overcrowding and overdevelopment in the study area. Although several possible backcountry modifications were shown on the questionnaire form to hikers, all were rejected by most backcountry users. Changes that received the most support related to the hikers need for more and better backcountry information This background resource and visitor inventory is examined with respect to campground and trail facility proposals made by Parks Canada in 1972. The intent is to show how the resource and visitor inventories can assist in the evaluation of park planning proposals. It is hoped that the inventory information presented will be useful to park managers and planners in a general way, and specifically in the formulation of land use decisions for Yoho Valley. / Forestry, Faculty of / Graduate
