Aspirant onderwysers se persepsies van omgewingskwessiesNel, Karen 07 September 2012 (has links)
M.Ed. / The literature study cleary revealed that the continuous interaction of human beings with their environment is beneficial both to the environment and to human beings, but with a price attached which has to be paid by the environment. The price paid is evident in the environmental problems with which the world is currently faced. The environmental crisis is characterised by an increase in the human population which is threatening the earth at an alarming rate and which leads in turn to soil erosion, air and water pollution and the application of destructive pressure on resources. The habitats of natural life forms are currently in the process of disappearing and certain species have already become extinct (Smith, Carlson, Masters & Donaldson, s.a.:3). UNESCO-UNEP (1988:25/30/31) corroborated the above by indicating that the primary problem involved in respect of all environmental problems is the population explosion, which places more pressure on resources (plants, animals, energy, water, soil and air). The interaction of human beings with nature has, in fact, entailed certain advantages for nature, but at the same time has also created new problems which have plunged the environment into a crisis. There is ample proof to be found in literature that an environmental crisis has been identified and that possible solutions to the problem have been found. The call to action culminated in 1972 in the Stockholm Conference, which was attended by world government structures. The outcome of this was the Belgrade Charter of 1975. Subsequently, the awakening of environmental awareness reached a catalytic phase in 1977 with the Tbilisie Conference which laid the foundation for the establishment fo principles, objectives and aims for Environmental Education. The central role which should be played by the educationist in this connection, is clearly outlined: Agenda 21 (Chapter 36): "...education is critical for the promotion of sustained development" (EEP1, 1995b:12). In every respect, South Africa forms part of this international environmental issue. The fact that this is, in fact, generally realised is evident in the White Paper on Environmental Education of 1989, which was a result of the meeting on Environmental Education at Treverton College, Mooi River. The term Environmental Education is now recognised as a full-fledged concept in its own right in formal education (White Paper on Education and Training (1995:20); the Reconstruction and Development Programme (RDP) document (1994); the International Development Research Centre (IDRC) document (1994:6); and the Committee on teacher eduction policy [norms and standards for teacher education] (Cotep) document (1995:41)), as quoted by Joubert & S teen kamp (1995:26/27). In this way, the problem of the community has also become the problem of the school curricula. It should therefore be accepted that schools should accord a high priority to environmentally-related problems in the community. The central role played by the teacher in environmental awareness is corroborated by various documents and writers. Two quotations will suffice in this connection: The Brutland report of 1987 states the problem as follows: '... the world's teachers ... have a crucial role to play in helping to bring about the extensive social changes needed for sustainable development" (EEPI, 1995b:12). Knapp (1975:209), as quoted by Raath (1994:4) states in this connection: Teachers and students alike can teach a lot about care and respect for the environment. They can also teach disregard and destruction of the earth": In this study, the status of the knowledge of aspirant teachers was revealed in respect of six environmental issues, namely, overpopulation, air pollution, water, soil, and plant and animal species. The relationship between factors such as external responsibility, restriction on individuals and responsibility for environmental education were also investigated. The respondents were comprised of aspirant teachers (final-year student teachers) of three South African Universities, namely the Rand Afrikaans University, the University of the Orange Free State and Vista (Free State) in the following study fields: Languages, Mathematics, Humanities, Economics and Physical Sciences, as well as other fields.

Public perception and response to extreme heat eventsPorter, Raymond E. 03 January 2014 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / In the United States extreme heat events have grown in size and stature over the past 20 years. Urban Heat Islands exacerbate these extreme heat events leaving a sizable portion of people at risk for heat related fatalities. The evidence of this is seen in the Chicago heat wave of 1995 which killed 500 people over the course of a week and the European heat wave of 2003 which killed 7,000 people in the course of a month. The main guiding questions then become how government and the media can most effectively warn people about the occurrence of extreme heat events? Should extreme heat warnings be issued by T.V., newspaper or by radio? Even if warnings are issued will the population at large still change their behavior? Another possible question is whether people most vulnerable to extreme heat will change their behavior? A survey in 2010 by NASA will be the main basis for this analysis. This survey set out to see how well people in Phoenix, Philadelphia, and Dayton responded to extreme heat alerts by changing their behavior.

Survive or thrive : creating options for sustainable communities in rural ScotlandWinther, Anne M. January 2014 (has links)
Environmental and socio-economic crises are creating compelling needs for radical social change. This project investigated the options and barriers for three Scottish rural communities (Fintry, Killin and Kinlochleven) to become sustainable and thrive in a future resource-constrained world. A unique, holistic and mixed methods approach was used to assess baseline sustainability, envision and model futures and develop possible options for sustainability. Central to this investigation was the development of a strong and holistic model of a sustainable community: the sustainable community design (SCD). This framework shaped the assessment of each community’s baseline sustainability. Sustainability was measured for the ten aspects of the SCD using a scorecard approach with a basket of indicators populated by primary data (collected in a household survey) and secondary data (national statistics). Sustainable consumption was analysed using the Resources and Energy Analysis Programme (REAP) to generate each community’s ecological footprint (EF) and results were compared to current estimates of per capita world biocapacity to gauge sustainability. Even the most sustainable community was only sustainable in three out of ten of the SCD’s aspects and this community had the highest EF. Although the most deprived community had the lowest EF, it was unsustainable in all ten SCD aspects. The results reflected the heterogeneity of rural communities and complexity of sustainability measurement. The SCD scorecard approach for sustainability measurement was shown to be sensitive and robust and can be applied to rural communities across Scotland. Future visions were created in focus groups, in which participants were asked to envision what their community would need to thrive in 2030 under the scenario of peak oil and a low carbon economy. Vision ideas and examples of best practice and technological innovation were used to create narrative scenarios for modelling transport, food and energy futures. The scenarios’ EFs were calculated in REAP for three discrete levels of change: a marginal change, a step change and radical transformation. The results suggested that radical transformation is required for communities to become sustainable. Key features are likely to be re-localised and highly co-operative societies, which utilise technological innovations (such as electric cars powered by renewable energy) and share resources to maximise opportunities for living in rural areas. A community’s transformation is likely to be bespoke and require local control, requiring changes to governance and supportive policy. Key barriers identified were availability of affordable technological innovations, energy injustice, power to achieve self-determination, community governance, property rights and sustainability literacy. A process model, incorporating the SCD scorecard approach, was proposed for furthering sustainable community development and research. In taking an interdisciplinary and mixed methods approach, this study has pioneered a novel approach to the holistic enquiry of the options for creating sustainable rural communities.

Social development versus saving nature? : a case study in environmental ethicsMagosha, Tendani Amos 12 1900 (has links)
Thesis (MPhil)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: This research project has been purposed at shedding light and bringing
clarity and practical resolution to the ethical dilemma brought about by
seemingly incompatible principles and value positions associated with the
two contentious issues: social development and nature conservation. In
view of exposing the contentions between the two above-mentioned value
positions, this project has pitted anthropocentrism against
biocen trism / ecocen trism.
However, as alluded to in this research, many people in developing
countries, South Africa included, are victims of poverty and hunger which
need redress. Unfortunately the alleviation of the same has been made
possible through ruthless exploitation and maximum expansion of natural
resources and in the process, the environment suffered much. However,
with social development, the natural environment is often sacrificed and
conversely with the protection and preservation of nature, man is then
condemned to destitution.
With the introduction and the case expose forming the introduction of this
research project in Chapter 1, Chapter 2 is devoted to the research
methodology used throughout this project. Also, given the problem
statement, endeavours to search for answers to the central questions are
outlined. An analysis of the case study is also made in this chapter.
Chapter 3 deals with the weighing of the classical dilemmas namely:
anthropocentrism versus biocentrism / ecocentrism and this further entails
the notion of justice versus conservation pertaining the case in point. These classical dilemmas are put into critical perspective in Chapter 4
wherein monistic value approaches are exposed in terms of their failures.
Precisely, the either-or choices following from pure theoretical principles are
put into question with reference to the case under discussion. An
alternative, namely the pragmatic approach, which maintains a multiplicity
of values, is hereby brought into play.
Chapter 5 entails a critical appraisal of the decision to be taken by the
Makhado Municipality Council with regard to the development of the
shopping complex or the protection of the indigenous tree sanctuary. In
conclusion, recommendations and suggestions are stated within the
context of the case in point. However, it is imperative to note that these
recommendations and suggestions should be read in conjunction with one
another, and not in isolation from one another. Furthermore, the same
should not in anyway be indiscriminately used as a universal standard in
any similar or related case.
Further research on this ethical debate is encouraged. / AFRIKAANSE OPSOMMING: Die doel van hierdie navorsingsprojek is om helderheid en 'n praktiese
oplossing te kry met betrekking tot die etiese dilemma wat voortspruit
uit die oeriskynlik onversoenbare beginsels en waardeposisies wat
geassosieer word met twee omstrede kwessies, naamlik sosiale
ontwikkeling en natuurbewaring. Met die oog daarop om die
kwelpunte rondom bogenoemde twee waardeposisies aan die lig te
bring, stel hierdie projek antroposentrisme teenoor
biosentrisme / ekosentrisme.
Baie mense in ontwikkelende lande, insluitend Suid-Afrika, IS
slagoffers van armoede en hongersnood, soos aangedui word in die
loop van hierdie navorsing. Hierdie situasie noodsaak regs telling.
Pogings om verligting te bring in hierdie verband, lei egter tot die
genadelose eksploitasie en maksimum ontwikkeling van natuurlike
hulpbronne. In hierdie proses word die omgewing ernstig beskadig.
Die ongelukkige toedrag van sake is dus dat sosiale ontwikkeling
dikwels geskied ten koste van die omgewing, terwyl die beskerming en
bewaring van die omgewing op sy beurt dikwels die mens behoeftig
laat.
Hoofstuk 1 van hierdie navorsingsprojek bevat 'n inleiding en
beskrywing van die geval onder bespreking, terwyl Hoofstuk 2 gewy
word aan die navorsingsmetodologie wat in hierdie projek gebruik
word. Dit bevat ook 'n skets van die pogings om antwoorde te soek op
die sentrale vrae van die probleemstelling, en 'n analise van die
gevallestudie. In Hoofstuk 3 word die klassieke dilemmas wat verband hou met die
betrokke probleem opgeweeg, naamlik antroposentrisme teenoor
biosentrismej ekosentrisme, en die idee van geregtigheid teenoor die
idee van bewaring.
Bogenoemde klassieke dilemmas word in 'n kritiese lig beskou in
Hoofstuk 4 deurdat die tekortkominge van monistiese
waardebenaderings uitgewys word. Die 6f-6f keuses wat volg uit
suiwer teoretiese beginsels word bevraagteken met verwysing na die
geval onder bespreking. 'n Pleidooi word uiteindelik gelewer vir 'n
alternatiewe pragmatiese benadering wat eerder 'n veelheid van
waardes betrek.
Hoofstuk 5 bevat 'n kritiese beoordeling van die keuse wat die
Makhado Munisipaliteitsraad moet maak tussen die ontwikkeling van
'n winkelkompleks of die beskerming van 'n inheemse boomreservaat.
Ter afsluiting word aanbevelings en voorstelle gemaak in verband met
die kwessie onder bespreking. Dit is egter belangrik om daarop te let
dat hierdie aanbevelings en voorstelle nie apart van mekaar beskou
moet word nie, maar eerder saam gelees moet word. Dit is verder ook
belangrik dat die aanbevelings en voorstelle wat met betrekking tot
hierdie geval gemaak word nie sonder meer gebruik moet word as 'n
universele standaard vir soortgelyke of verwante gevalle nie.
Verdere navorsing oor hierdie etiese debat word aangemoedig.

Constituting community: expanding perceptions of community in Rawlings's Cross Creek and Thoreau's WaldenUnknown Date (has links)
Both Thoreau and Rawlings call attention to humanity's need to expand its perceptions and interpretations of what it means to be a part of a community in Walden and Cross Creek, respectively. Building on the established idea of what it means to be incorporated into a human community, each author also implores his or her readers to extend the perceived boundaries of what comprises a "community" to include the natural world. Ultimately, both texts point to the need for the establishment of what Aldo Leopold calls a land ethic, which requires the re-drawing of communal boundaries to include the land with man as a citizen rather than a conqueror of Nature. Thoreau and Rawlings demonstrate how an individual can start to expand his or her conception of community to move closer to Leopold's ideal by recounting the different experiences they have with human society and nature while living at Walden Pond and in Cross Creek, Florida. However, each author uses different approaches. Thoreau concentrates primarily on reflecting upon improving his individual self in order to eventually improve his Concord community. Rawlings, on the other hand, makes a greater effort to reflect upon her interactions with the people of Cross Creek in addition to her interactions with Nature in order to strengthen her bonds with these things. Such a difference causes Rawlings to be read as presenting a re-vision of Thoreau's ideas about the relationship between humankind, one's community, and Nature. While the kinds of experiences Thoreau and Rawlings encounter might be different, in the end it is their emphasis on the importance of an individual's relationship to the community-one that includes both humans and Nature-that resonates with readers. / by Julianne Curran. / Thesis (M.A.)--Florida Atlantic University, 2010. / Includes bibliography. / Electronic reproduction.
