The evolution, substance and application of environmental impact assessments in South AfricaParkes, L. 03 1900 (has links)
Thesis (MS en S)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: Environmental impact assessments have become increasingly popular over the past
few years, by necessity and due to the general increase in environmental
awareness. By definition, environmental impact assessment is a process having the
ultimate objective of providing decision makers with an indication of the likely
consequences of their intended actions. First popularized in the United States of
America in the seventies, environmental impact assessments have since evolved
worldwide into an effective decision making tool.
In South Africa, environmental impact assessments became legally enforceable in
1998 under the Environment Conservation Act (Act 73 of 1989) and presently serves
as an effective tool in facilitating decision making for sustainable development. A
large number of impact assessments are at present being produced for all
categories of activities, but questions arise about the effectiveness of these
assessments in fulfilling their intended purpose.
The present study aims to answer these questions and provide insight into the
nature, content and standard of environmental impact assessment in South Africa by
examining the foundations and application of the concept. The main method of
research was the analysis of various assessments, already submitted to regional
authorities, on the basis of content, methods used, depth of analysis, degree of
public input and their overall contribution to the better understanding of the problem
at hand.
During the analysis many inadequacies and merits of these impact assessments
were revealed. The quality of reports ranged from good (about one third) to average
and poor (about one third). Shortcomings identified related inter alia to data
collection; ignorance of socio-economic factors; ignorance of cumulative effects; and
analysis and evaluation problems. The benefits that these impact assessments could bring about, were also analysed.
It was deduced that there were inherent benefits the most practical being that the
good reports assisted the decision making process considerably. Sustainable
development was also promoted.
It was found that the implementation of the concept still needs more stringent
management and monitoring with improved application and incorporation into the
present planning approach / AFRIKAANSE OPSOMMING: In die afgelope paar jaar het omgewingsimpakstudies (OIS) toenemend populêr
geword as gevolg van noodsaaklikheid en die algemene toename in
omgewingsbewustheid. By definisie is OIS 'n proses met die uiteindelike doel om
besluitnemers in te lig oor die waarskynlike gevolge van hul handelinge. OIS het
wêreldwyd ontwikkel in 'n effektiewe besluitnemingshulpmiddel sedert dit aanvanklik
tydens die sewentiger jare in die Verenigde State van Amerika gepopulariseer is.
Omgewingsimpakstudies is wetlik afdwingbaar in Suid Afrika sedert 1998 onder die
Wet op Omgewingsbewaring (Wet 73 van 1989). Dit dien as 'n effektiewe middel in
die fasilitering van besluitneming oor volhoubare ontwikkeling. 'n Groot aantal
impakstudies word tans opgestel vir alle kategorieë van aktiwiteite, maar die
effektiwiteit van hierdie studies in die vervulling van hul doelstellings word
bevraagteken.
Die doel van hierdie studie is om hierdie vraag te beantwoord en insig te verskaf oor
die aard, inhoud en standaard van impakstudies in Suid Afrika deur grondslae en
toepassing van die konsep te ondersoek. Die hoof metode van navorsing was die
ontleding van verskeie studies reeds ingedien by plaaslike owerhede, op grond van
inhoud, metodes gebruik, diepte van ontleding, graad van publieke deelname en hul
algehele bydrae tot 'n beter begrip van die probleem.
Tydens die ontleding is verskeie beperkings en meriete van impakstudies ontbloot.
Die kwaliteit van verslae het gewissel van goed (omtrent een derde) tot gemiddeld
en swak (omtrent een derde). Tekortkominge geïdentifiseer hou verband met o.a.
data insameling, onkunde van sosio-ekonomiese faktore, onkunde van kumulatiewe
effekte en ontleding-en evalueringsprobleme.
Voordele van impakstudies is ook geanaliseer. Die belangrikste was dat goeie
verslae besluitnemingsprosesse aansienlik kan bystaan. Volhoubare ontwikkeling is
ook bevorder. Daar is gevind dat die implementering van die konsep steeds strenger bestuur en
beheer benodig, met verbeterde integrasie in die beplanningsproses.

Geographical information systems for environmental impact assessment : a feasibility studyBrink, Ester 12 1900 (has links)
Thesis (MA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: This study acknowledges the status quo in South Africa as a country in transformation. Leaders concur that people live under the spell of the evil triplets of poverty, inequality and unemployment amidst the need for development and economic growth. In order to initiate positive change, the 1996 Constitution of South Africa supports integrated environmental management (IEM) and sustainability principles towards ecological, economic and social compromise. Furthermore, the National Environmental Management Act (NEMA) was legislated in 1996 along with the mandatory environmental impact assessment (EIA) tool in 1998. Despite this legislation being of global standards, current discourse highlights the need for new strategies and tools to improve IEM. The constraint lies in the implementation of policy as the EIA process is limited by inconsistency and project specific focus. Fortuitously technology has developed to levels where web-based tools encourage spatial awareness and individual responsibility for the environment. Usage of participative GIS supported by best practice in governance has the potential to successfully drive IEM.
This research builds on the integration of a policy instrument (EIA), spatial technology (GIS), development and human factors (people) as pillars of transdisciplinary methodology to collaborate and gather new information to expand knowledge and augment existing processes. The study objectives required rigorous research and involved a wide range of participants in a feasibility study to provide details of the viability of integrating GIS usage into EIA conduct in South Africa. Participants in the research were selected from the geographical scope of Cape Town and represent involved parties in EIA and potential users of GIS in EIA. The legislative scope is the Western Cape Province. Triangulation, a mixed method approach, was employed to collect and collate qualitative and quantitative information based on the opinions of involved parties in the IEM, EIA and GIS domains. Primary data collection methods included observation, fieldwork, informal, formal and focus group discussions as well as an e-mail questionnaire and a Likert scale e-survey. The knowledge gained was evaluated using SWOT and graphics. The findings indicated that the majority of participants agreed that technology and skills are available to design and develop a web-based application for GIS usage in EIA. However, from the outcome of the study the main challenge is not related to technical skills and capacity, but to align the EIA with IEM sustainability principles for effective decision making and self-regulation. It is therefore envisaged that web-based GIS usage in EIA based on IEM has the potential to reconnect the EIA process by uniting people in knowledge with easy access to information from a central data base repository to an on-line web-based platform that links time and space to inform decision making. / AFRIKAANSE OPSOMMING: Die uitgangspunt van hierdie studie is dat Suid-Afrika 'n land in transformasie is en die behoefte aan ontwikkeling en ekonomiese groei van kardinale belang is weens die armoede, ongelykheid en werkloosheid waaronder baie mense lei. Effektiewe omgewingsbestuur is uiters belangrik om omgewingsbesoedeling en agteruitgang te verhoed. Ten einde 'n positiewe verandering te inisieer, ondersteun die 1996 Grondwet van Suid-Afrika geïntegreerde omgewingsbestuur (GOB) en volhoubaarheidsbeginsels teenoor ekologiese, ekonomiese en sosiale kompromie. Die 1996 Nasionale Wet op Omgewingsbestuur (NEMA) het die omgewingsimpakstudie (OIS)-instrument in 1998 verpligtend verklaar. Die OIS wetgewing is gebaseer op hoë internasionale standaarde, maar ten spyte hiervan beklemtoon die huidige diskoers die behoefte aan nuwe strategieë om OIS in die praktyk effektief te belyn met die GOB beleid. Tans word die OIS proses beperk deur teenstrydigheid tussen gebruikers van die proses sowel as projekspesifieke fokus. Tegnologie het ontwikkel tot 'n vlak waar webgebaseerde GIS ruimtelike bewustheid aanmoedig en individuele verantwoordelikheid vir die omgewing aanbeveel en ondersteun word. Deelnemende GIS, ondersteun deur goeie regering, het die potensiaal om OIS en GOB suksesvol in die praktyk te implementer.
Hierdie navorsing bou voort op die integrasie van 'n beleidsinstrument (OIS), ruimtelike tegnologie (GIS) asook ontwikkeling en menslike faktore (mense) en ondersteun die transdissiplinêre metodologie om nuwe inligtig te versamel en vryelik te deel. Die studiedoelwitte het streng navorsingsmetodologie vereis deur 'n wye verskeidenheid van deelnemers te betrek in 'n ondersoek na die haalbaarheid van die integrasie van GIS gebruik in OIS in Suid-Afrika. Deelnemers aan die navorsing is gekies uit die geografiese domein van Kaapstad en was betrokke partye in omgewingsbestuur en potensiële gebruikers van GIS in OIS. Die wetgewende domein is die Wes-Kaap. 'n Gemengde-metode benadering is gevolg om kwalitatiewe en kwantitatiewe inligting te versamel en was gebaseer op die menings van die betrokke partye in die IEM, OIE en GIS terreine. Die kennis is geëvalueer met behulp van SWOT analise en grafika.
Die bevindinge dui aan dat die meerderheid van die deelnemers saamstem dat tegnologie en vaardigheid beskikbaar is om 'n program vir GIS-gebruik in OIS te ontwikkel. Die uitslag van die studie dui daarop dat die grootste uitdaging vir effektiewe besluitneming en self-regulering nie verband hou met tegniese vaardighede en kapasiteit nie, maar om die OIS te verenig met GOB-volhoubaarheid beginsels. Die vooruitsig is dus dat web-gebaseerde GIS gebruik in OIS gebaseer op GOB die potensiaal het om mense met kennis te verenig en omgewingsbestuur effektief in te lig.

Modelo de gestão ambiental: estudo de caso em triparia no sudoeste do ParanáMartini, Cezar Augusto 20 April 2012 (has links)
O agravamento dos problemas ambientais e sociais representa um quadro de insustentabilidade do atual padrão de desenvolvimento. Portanto, as empresas devem adotar instrumentos de gestão ambiental como uma das alternativas na busca da sustentabilidade. Este estudo prevê a aplicação de um modelo de gestão ambiental para a triparia implantada no sudoeste do estado do Paraná, visando aumentar o nível de sustentabilidade ambiental da empresa. Inicialmente foi realizada a caracterização da empresa, elaborando-se descrições e fluxogramas das atividades desenvolvidas, incluindo processo industrial, estações de tratamento de água e de efluentes líquidos, geração de vapor e de resíduos sólidos, frota de veículos e setor administrativo. A seguir, por meio de quadros de entradas e saídas, foi realizada a identificação dos aspectos ambientais de cada atividade, propiciando a análise ambiental da empresa, de forma qualitativa e quantitativa, confrontando-se a situação atual com a legislação ambiental, quando aplicável. Na próxima etapa, aplicando-se um instrumento de gestão, foi realizada a avaliação de impactos ambientais, que contempla a identificação e avaliação dos impactos. Concluindo, foram identificados impactos negativos, principalmente relacionados aos meios físicos e biológicos, que podem ser minimizados pela implantação dos programas e medidas sugeridos, entre eles redução no consumo de água, reuso de efluentes e águas pluviais, otimização do tratamento de efluentes, ajuste no processo de combustão, regularização das inconformidades legais. Por outro lado foram identificados impactos positivos, principalmente relacionados ao meio socioeconômico, que devem ser mantidos ou ampliados, para que a empresa possa aumentar seu nível de sustentabilidade. / The worsening environmental and social problems represents a framework of unsustainability of the current standard of development, therefore, the companies must adopt instruments of environmental management as an alternative in search of sustainability. This study provides an application of a model of environmental management for gut sectors implanted in the southwest Paraná, seeking to increase the level of environmental sustainability of the company. Initially it was carried out the characterization of the company, producing descriptions and flowcharts activities, including industrial process, water treatment plants and liquid effluents, steam generation and solid waste, fleet of identification of environmental aspects of each activity, allowing the environmental analysis of the company, qualitatively and quatitatively, confronting the current situation with the environmental legislation, when applicable. In the next step, by applying a management tool, was carried out the assessment of environmental impacts, which includes the identification and assessment of the impacts. In conclusion, negative impacts were identified, particularly related to biological and physical environment, that can be minimized by the implementation of the programs and measures suggested, among them reduction in water consumption, reuse of effluent and rainwater, optimization of the treatment of effluents, adjust in the combustion process, regularization of legal non-conformities. On the other hand were identified positive impacts, particularly related to the socio-economic environment, that must be kept or extended, in order to allow the company to increase its level of environmental sustainability.

A LOGÍSTICA DE TRANSPORTE E AS CADEIAS AGROPECUÁRIAS AVÍCOLA E SUINÍCOLA, IMPACTO SOCIAL E ECONÔMICO NO DESENVOLVIMENTO LOCAL DO MUNICÍPIO DE TOLEDO - PR / Transport Logistics and Aviculture and Swine Culture Agricultural Chains, Social and Economical Impact in the Local Development in the Municipality of Toledo PRManfroi, Armando Staudt 24 March 2008 (has links)
The economy in the west of the State of Paraná is market by the strong participation of the agricultural activities; much from what is produced either in the State or in the country is native of this region. Particularly for the Municipality of Toledo, the aviculture and swine culture are the main agricultural. These are directly mediated by the activities of transport logistics, which play the important and directly responsible role by the appropriate development of the agricultural. Thus, this search shows the development of a model which aims to measure the impacts caused by the transport logistics in the aviculture and swine culture. Thus, it has been attempted to answer what the economical and social impacts are that the transport logistics cause on birds and swine chains, that justified by the characteristic of importance which the transport activity has for the activities, due to the fact that it is treated of an activity that provides the connection among several initial productive stages. The data collection has contemplated the search for information in local public organs and private companies which are directly connected to the activity; this information were fundamental to the is referred to the construction of indicators about the studied activities. From the collected data, it has been developed a matrix of analysis from this data which shows the direct relation among the global numbers in the Municipality (e.g., the total of employment in the Municipality in relation to the total employment from the bird and swine chains). It has been evident during the search the essential role of the transport logistics, and it can be claimed that there is a high level of dependence of the activities that involve bird and swine production in the transport logistical services, thus, any alteration in the transport configuration may bring direct consequences to aviculture and swine culture, interfering in the results and in the production. It is believed that this study has contributed to the explanation of the importance of the transport activities in the context of birds and swine production for the Municipality, and indirectly for the local economical and social development. / A economia do oeste do estado do Paraná é marcada pela forte participação das atividades agropecuárias. Muito do que se produz no estado e no país é oriundo dessa região. Em específico para o município de Toledo, a avicultura e a suinocultura são as principais atividades agropecuárias. Estas são diretamente mediadas pela logística de transporte, que assume papel indispensável e diretamente responsável pelo desenvolvimento adequado destas. Assim esta pesquisa apresenta o desenvolvimento de um modelo que objetiva mensurar os impactos causados pela logística de transportes nas atividades, avícola e suinícola. Dessa forma se buscou responder quais são os impactos econômicos e sociais que a logística de transportes causa nas cadeias de aves e suínos, isso justificado pela característica de importância que os transportes têm para estas cadeias produtivas, visto que se trata de uma atividade que proporciona a ligação entre as diversas etapas produtivas iniciais. A coleta de dados contemplou a busca de informações em órgãos públicos e empresas privadas locais com ligação direta à atividade. Essas informações foram fundamentais para a construção de indicadores sobre as atividades estudadas. A partir dos dados coletados se desenvolveu uma matriz de análise desses dados que apresentam a relação direta entre os números das atividades de avicultura e suinocultura, comparadas com números globais do município (como por exemplo, o total de empregos do município em relação com o total de empregos das cadeias de aves e suínos). Ficou claro durante a pesquisa, o papel fundamental da logística de transporte, e pode-se dizer que existe um alto grau de dependência das atividades que envolvem a produção de aves e suínos dos serviços logísticos de transporte. Dessa forma, qualquer alteração na configuração dos transportes pode trazer conseqüências diretas à avicultura e suinocultura, interferindo nos resultados e na produção. Acredita-se que este estudo contribuiu para o esclarecimento da importância das atividades de transportes no contexto da produção de aves e suínos para o município, e indiretamente para o desenvolvimento econômico e social local.

Áreas degradadas pela explotação de cassiterita : avaliação das condições dos agregados e atividades biológicas /Mello, Giovanna Frederici de. January 2015 (has links)
Orientador: Admilson Írio Ribeiro / Banca: Gerson Araújo de Medeiros / Banca: Fátima Conceição Márquez Piña-Rodrigues / Resumo: Uma das maiores riquezas naturais do Brasil é o seu potencial mineral. A região amazônica é conhecida pela abundância de recursos minerais, podendo destacar o topázio, petróleo, e principalmente a cassiterita. Como consequência da mineração, o ecossistema vem sofrendo um processo constante de degradação. Um importante artifício na exploração de recursos minerais é a reabilitação e/ ou recuperação das áreas degradadas, para isso, é necessário estabelecer indicadores de degradação, assim como de qualidade do solo associada a sua biota, levando em consideração que esse é um ambiente dinâmico, heterogêneo e complexo de características físicas, químicas e biológicas diversificadas. Desse modo, o objetivo deste trabalho foi estudar a associação entre variáveis da atividade biológica do solo e variáveis morfométricas dos agregados, visando estabelecer uma função de pedotransferência para identificar de maneira expedita os melhores indicadores de recuperação para as áreas experimentais localizadas em substrato piso de lavra na Floresta Nacional do Jamari-RO.Os resultados apresentaram grande variabilidade no conjunto das variáveis morfométricas e uma menor dispersão dos dados para as variáveis biológicas. A metodologia de análise da amplitude das diferenças entre os parâmetros nas áreas analisadas permitiu a comparação entre as áreas em recuperação facilitando a interpretação gráfica das diferenças. Foi possível por meio da correlação canônica, determinar combinações lineares entre o conjunto de variáveis da diversidade biológica do solo e do conjunto das variáveis dos parâmetros morfométricos dos agregados do solo Considerando que o modelo das combinações lineares não apresentou um ajuste satisfatório, a definição de um índice expedito ficou comprometida, pois haveria necessidade de se estudar os problemas de multicolinearidade e intercorrelação entre as equações... / Abstract: One of the biggest natural wealth of Brazil is its mineral potential. The Amazon region is known for the abundance of mineral resources, and can highlight the topaz, oil, and especially tin. As a result of mining, the ecosystem has undergone a constant process of degradation. An important tool in the exploration of mineral resources is the rehabilitation and / or restoration of degraded areas, for this it is necessary to establish degradation indicators, as well as soil quality associated with its biota, taking into account that this is a dynamic environment, heterogeneous and complex physical, chemical and biological diverse. Thus, the objective of this work was to study the association between variables of biological soil activity and morphometric variables of households, aiming at a Pedotransfer function to identify expeditiously the best indicators of recovery for the experimental areas located in mining floor substrate the National Forest of Jamari-RO.Os results showed great variability in all the morphometric variables and a lower dispersion of data for biological variables. The analysis method of the amplitude differences between the parameters analyzed in the areas allowed the comparison of the areas facilitating recovery graphical interpretation of differences. It was possible through the canonical correlation determine linear combinations of the set of variables of soil biodiversity and to all the variables of the morphometric parameters of soil aggregates whereas the linear combination model has not submitted a satisfactory adjustment, the definition of an index expeditious been compromised, as there is need to study the problems of multicollinearity and intercorrelation between the predictive equations of biological activity through morphometric variables. / Mestre
