[pt] O gerenciamento de riscos é um dos tópicos de pesquisa mais atraentes dentro do campo da gestão da cadeia de suprimentos. Devido à crescente diversidade e à extensão das cadeias, as questões ambientais tornaram-se hoje um tópico de pesquisa desafiador dentro deste contexto. Além disso, os recentes escândalos ambientais trazem à tona a negligência acerca das questões ambientais por parte de grandes empresas. O presente estudo explora, portanto, a gestão de riscos ambientais na cadeia de suprimentos. Para isso, foi realizada, inicialmente, uma revisão sistemática da literatura a fim de identificar os riscos ambientais presentes nas cadeias de suprimentos de uma empresa, a reação dos stakeholders perante esses riscos, que se desdobram em consequências para as empresas, bem como as estratégias ambientais para mitigação dos riscos. São identificados quatorze riscos ambientais, três principais consequências e dezenove estratégias que se relacionam através de um framework proposto. Posteriormente, um múltiplo estudo de caso é conduzido em três empresas situadas no Brasil, com a finalidade de verificar a relação das variáveis identificadas na literatura com as realidades organizacionais. Constata-se que a maioria dos riscos e estratégias ambientais advindas da revisão da literatura é também observada nas empresas estudadas e, dentre as consequências, as mais citadas pelas organizações são perdas reputacionais e financeiras. A partir dos estudos de casos, é possível complementar e validar os estudos acadêmicos existentes, endossando, assim, a discussão sobre o gerenciamento de riscos ambientais na cadeia de suprimentos. / [en] Risk management in supply chains has emerged as one of the most attractive research topics in the supply chain management field. Due to increasing diversity and the growing size of supply chains, environmental issues have today become a challenging research topic in supply chain risk management. Besides that, the recent environmental accidents bring to light the neglect of environmental issues by large companies. Thus, the present study explores the environmental risk management in supply chains. For this, a systematic literature review is carried out in order to identify the environmental risks present in the supply chain of a company, the reaction of the stakeholders to these risks, which unfold as consequences for the companies, as well as the strategies for mitigating these risks. It is identified fourteen environmental risks, three main consequences and nineteen strategies that are related by a proposed framework. Subsequently, a multiple case study is conducted in three companies located in Brazil, with the purpose of verifying the relationship of the variables identified in the literature with the organizational realities. It is verified that most of the risks and environmental strategies coming from the academic literature are observed by the companies and, among the consequences, the most cited ones are related to the company s reputation and financial consequences. From the cases studies, it is possible to complement and validate the existing academic studies, in order to endorse the discussion about environmental risk management in the supply chain.

Les systèmes de gestion intégrée en environnement et en santé et sécurité du travail (SGI) sont un nouveau paradigme de gestion dans les organisations modernes. Ces systèmes sont construits à partir des normes ISO 14001 et d’OHSAS 18001, basées sur la prévention des risques et le principe de précaution. La littérature sur les SGI témoigne d’un marasme conceptuel prédominant depuis plus de 10 ans; elle insiste sur l’urgence d’un consensus taxinomique et conceptuel afin de définir les systèmes de gestion intégrée et de différencier le mécanisme d’intégration de celui de l’implantation. Cette lacune conceptuelle enlise les connaissances dans un fossé épistémologique, retardant ainsi le débat dans ce nouveau champ d’études. Les rares connaissances dont nous disposons dans ce domaine proviennent de quelques études théoriques et de six études empiriques, toutes préoccupées par la compatibilité des multiples systèmes et des avantages économiques de leur intégration. Les évidences engendrées par ces études sont insuffisantes pour appréhender la dynamique du nouveau paradigme dont les effets demeurent peu connus. Cette situation révèle l’urgence d’agir dans un contexte où l’utilisation des SGI se multiplie, et où leur tendance à minimiser l’importance des risques devient de plus en plus préoccupante. Aucune étude ne s’est encore penchée sur l’implantation d’un SGI en environnement et en santé et sécurité du travail construit uniquement à partir des normes ISO 14001 et d’OHSAS 18001. Cette connaissance est importante pour expliquer les effets de tels systèmes. C’est dans cette perspective que nous avons réalisé cette première étude empirique d’un SGI selon les normes ISO 14001 et d’OHSAS 18001. Nos questions de recherche portent sur le mode, le degré d’implantation, les effets du SGI, ainsi que sur les facteurs contextuels qui interviennent pour expliquer les variations dans le degré d’implantation et les effets du SGI. Il s’agit d’une recherche à prélèvement qualitatif qui repose sur un devis d’étude de cas, avec des niveaux d’analyse imbriqués, et comportant une double visée descriptive et explicative. Notre échantillon, de type raisonné, regroupait trente-cinq intervenants provenant de différentes instances hiérarchiques ; il incluait également des représentants syndicaux. Notre échantillon était composé de 7 usines, accréditées aux normes ISO 14001, OHSAS 18001, et dispersées dans différentes villes du Québec. Ces usines différaient tant par leur technologie, leur âge, leur taille, et leurs types de production. Nos données ont été recueillies en 2004; elles sont basées sur des entrevues semi dirigées, sur des observations directes lors de la visite des lieux; elles s’appuient aussi sur des consultations de documents internes et sur des outils électroniques implantés. La transcription des entrevues effectuée, le contenu des discours a été catégorisé selon les cinq dimensions du SGI: engagement, planification, mise en opération, contrôle et revue de la direction. Une condensation horizontale avait précédé l’analyse de chaque cas et l’analyse transversale des cas selon une approche à la fois inductive et déductive. Les résultats de notre recherche ont révélé deux modes d’implantation : le mode d’enrichissement et le mode de fusion. Ces modes dépendaient de la nature des structures fonctionnelles en place. La visée d’amélioration continue à la base du SGI n’avait pas réussi à concilier les approches traditionnelles bottom up et top down qui ont dominé cette implantation; son mécanisme était guidé par 4 types de stratégies : l’économie des ressources, le contrôle des forces d’influences, la stratégie des fruits faciles à cueillir et la stratégie à petits pas. Pour analyser le degré d’implantation, nous avons tenu compte de l’effort de structuration du SGI et de la force d’utilisation des processus implantés à chacune des cinq dimensions du SGI. Les résultats de notre recherche révèlent une variabilité certaine du degré d’implantation entre les usines d’une part, et entre les processus associés aux cinq dimensions du SGI d’autre part. L’analyse des discours a permis de produire cinq hypothèses qui soutiennent l’effort de structuration et la force d’utilisation du SGI: (i) l’hypothèse de la force de cohésion, (ii) l’hypothèse de la spécificité du processus, (iii) l’hypothèse de la portée du processus, (iv) l’hypothèse de la capacité organisationnelle, (v) l’hypothèse de l’acceptation du changement. L’implantation du SGI était soumise à l’influence de multiples facteurs; ils étaient de nature politique, structurelle et organisationnelle. Ces facteurs avaient agi sur le processus d’implantation en amorçant une cascade d’interactions au cours desquelles leurs forces d’influences se renforçaient, se neutralisaient ou s’additionnaient pour affecter le degré d’implantation. Les facteurs facilitant touchaient surtout l’effort de structuration ; ils incluaient : l’expérience des systèmes de gestion, l’implication de la direction, celle du syndicat ou du CSS, la structure organisationnelle, le niveau d’éducation, l’âge et la taille de l’usine. Quant aux facteurs contraignants, ils agissaient sur la force d’utilisation ; ils incluaient : la lourdeur procédurale, le manque de temps, le manque de formation, le manque de ressources, la culture organisationnelle, la structure organisationnelle, le fossé intergénérationnel, l’absence du syndicat et l’âge de l’usine. Trois effets proximaux escomptés par l’entreprise ont été observés. (i) La rigueur de la gestion était associée à l’application des exigences du SGI; elle touchait la gouvernance en environnement et en santé et sécurité du travail, les mécanismes de gestion et les procédés de production. (ii) La standardisation était reliée au mode d’implantation du SGI; elle concernait les pratiques, les outils, les méthodes de travail et l’organisation des ressources. (iii) La rupture des silos est un effet relié au mode d’implantation du SGI; elle touchait les structures départementales, les frontières professionnelles, les relations et climat de travail. Ces effets proximaux avaient provoqué plusieurs effets émergents, plus distaux: une augmentation du pouvoir de contrôle syndical, un renforcement de la légitimité des recommandations soumises par les spécialistes professionnels, la création de réseaux inter organisationnels et le transfert du savoir. L’implantation du SGI avait transformé la gouvernance et les pratiques en environnement et en santé et sécurité du travail dans les sept usines. Toutefois, elle ne semblait pas garantir l’immunité du processus de gestion des risques à l’environnement ni à la santé et sécurité du travail. Sa capacité à diluer les risques devait retenir l’attention des politiques de santé publiques et des programmes de prévention des risques à l’environnement et à la santé et sécurité du travail. L’amélioration de la gestion des risques demeurait un effet attendu non observé et soumis à des facteurs contextuels qui pourraient l’empêcher de se concrétiser. À cet égard, le transfert du savoir, renforcé par l’émergence des réseaux inter organisationnels, semblait offrir une avenue beaucoup plus prometteuse et accessible. C’est l’une des contributions de cette recherche. Elle a aussi (i) proposé une typologie des modes d’implantation et des effets du SGI (ii) préconisé une méthode détaillée d’une meilleure appréciation du degré d’implantation (iii) précisé le rôle des facteurs contextuels dans l’explication des variations du degré d’implantation et dans la production des effets, (iv) proposé des hypothèses sur la structuration et l’utilisation du SGI (v) offert une perspective plurielle et approfondie de la dynamique de l’implantation du SGI grâce à la variété de l’échantillon des répondants et des usines. Il s’agit de la première étude de terrain dans le domaine. À notre connaissance, aucune autre étude n’a eu de tels résultats.

These systems are built mainly from the ISO 14001 and OHSAS 18001 norms, which are based on risk prevention and the precautionary principles. For the past ten years, the literature on IMS has been governed by a conceptual stagnation, which is now begging for a taxonomic consensus in order to define IMS, clarify both integration and implementation processes, and to move beyond structures to address processes. As a result, the knowledge about IMS has been embroiled in an epistemological ditch, thus delaying debates in this emerging field of study. Scarce publications about IMS come from a few theoretical papers and six empirical investigations, all preoccupied by systems compatibility and the economic advantages of management systems integration. Evidence generated by these studies is not sufficient to apprehend the dynamics of the new paradigm, whose effects remain little known about until now. This situation is becoming alarming in a context where the use of integrated environmental health and safety management systems is increasing and where these IMS are raising concerns about their capacity to minimize risk in one domain or another. So far, no study has investigated the implementation of integrated environmental health and safety management systems built from ISO 14001 and OHSAS 18001 norms. Such knowledge is cardinal to help explain the effects of such IMS. It is in this perspective that we have undertaken this first empirical study of an IMS built from ISO 14001 and OHSAS 18001. Our research questions address the mode of implementation, the degree of implementation and the effects of the IMS, as well as the contextual factors whose influence on the implementation help explain the variations in the degree of implementation and the effects of the IMS. This qualitative inquiry uses a single case study with multiple levels of analysis. Our purposeful sample of thirty five participants was drawn from different levels of hierarchy, including union executives and representatives. Our purposeful sample of plants consisted of seven ISO 14001 and OHSAS 18001 certified plants located in different cities in Quebec, Canada. These plants differed by their technology, their age, their size and their types of production. Our data were collected in 2004 from semi-directed interviews, direct observation during site visits, and consultation of documentation and assessment of functionalities of implemented management tools. Interviews were transcribed verbatim and their content was categorized based on the five dimensions of the IMS: commitment policy, planning, deployment, control and management review. Horizontal condensation preceded within case and transversal analysis, using both inductive and deductive approaches. Our results indicate two implementation modes: the enrichment mode and the fusion mode, both related to the functional structures in place. Despite its aim of continuous improvement, the IMS was unable to reconcile the two traditional approaches of top down and bottom up, which have dominated this implementation which was supported by four strategies: economy of resources, control of influence, low hanging fruits and the small steps strategy. In order to analyze the degree of the IMS implementation, we have taken into consideration two aspects of the process: The effort of structuring the IMS and the scope of utilization of the implemented processes. Our results showed evidence of variation in the degree of IMS implementation; this variation was observed among the plants as well as among the processes implemented at each one of the five IMS steps. The analysis of discourses has allowed the production of five hypotheses that support IMS structuring and utilization (i) Cohesion forces hypothesis (ii) Process specificity hypothesis (iii) Scope of process hypothesis (iv) Organizational readiness hypothesis (v) Acceptance of change hypothesis. IMS implementation was influenced by political, structural and organizational factors. These factors have played their influence by catalyzing non -linear interactions, during which their influence could be neutralized, added or reinforced, hence generating variations in the degree of implementation. Facilitating factors have affected the effort of IMS structuring and included: experience working with management system, upper management commitment, implication of union or of health and safety committee representatives, organizational structure, level of education, plant age and plant size. Inhibiting factors have affected mainly the utilization of implemented processes. These factors included: procedural heaviness, lack of time, lack of training, lack of resource, organizational culture, organizational structure, intergeneration gap and lack of union implication. Three proximal effects anticipated by the organization under study were observed. (i) Increase in the rigor of management is an effect which was associated with the application of IMS requirements. It implied EHS governance, integrated management mechanisms and production processes (ii) Standardization is an effect which was associated rather with the implementation mode. It implied EHS practices, tools, work methods and organization of resources. (iii) Rupture of departmental silo is an effect associated with the mode of implementation. It involved organizational structures, professional boundaries and the working relations and climate. These proximal effects have induced several emerging effects, which were more distal. These were: increased control power of the union; increased legitimacy of recommendations by EHS professionals; creation of inter-organizational network and knowledge transfer. The implementation of an integrated management system in environment, occupational health and safety has transformed EHS governance and practice in all seven plants. However, this was not sufficient to grant immunity to EHS risk management processes. The potential of IMS to dilute risks should be of concern to public health policies, as well as to risk prevention programs on environment and on occupational health and safety. Improvement of EHS risk management was an expected effect but was not observed at the moment of our study. Several contextual factors may have intervened to alter its occurrence. To this regard, knowledge transfer, reinforced by the emergence of intra-organizational networks, seem to offer a very promising and affordable alternative. This is one of the contributions of our study research, which, in addition has (i) proposed a nomenclature to classify the modes of implementation and effects of IMS (ii) proposed a detailed method to appreciate the degree of implementation (iii) stated the roles played by contextual factors in explaining variations in the degree of IMS implementation and in the production of effects (iv) proposed a hypothesis on IMS structuring and utilization (v) through the diversity of our sample, offered a plural and sound perspective on the dynamics of IMS implementation. This is the first field study of this new paradigm. To our knowledge, no other study has produced such results.

This thesis seeks to uncover women’s concerns about chemicals in the household, and, more specifically, in cleaning products. The research is based on semi-structured interviews with women who are primarily responsible for household cleaning and who consciously avoid conventional cleaning products. From a sociological standpoint, the topic remains unstudied. The women were critical of greenwashing and the institutions responsible for chemical regulation. Further, the women’s chemical-free lifestyle defied conventional definitions of activism. Sociological theories of risk are used to help understand women’s avoidance of chemicals. It was found that tenets of the precautionary principle were reflected in their reasoning for avoiding chemicals. Recent biomonitoring and body burden studies have influenced women’s knowledge of chemical risk and their decision to avoid them. The thesis demonstrates that risk-management, in this context, has become an individualized pursuit reflective of the neo-liberal ideology informing chemical regulation. / Canadian Institutes of Health Research

In the environmental context banks face direct, indirect and reputational risks from their internal operations and their external business activities. The current specific focus on the protection of the environment makes it essential for banks and their directors to be aware and stay on top of potential risks and liabilities. This is especially so because banks’ directors can be criminally prosecuted for environmental crimes. The application and effect of the Prevention of Organised Crime Act 121 of 1998 (POCA) on persons convicted of an environmental crime or crimes has been identified as a possible new or added risk for banks and their directors. Banks in addition to their normal environmental risk and liabilities also need to contend with the possibility of lender liability. Existing legislation pertinent to lender liability does not expressly or specifically deal with lender liability. Absence of judgements on lender liability further exacerbates the risks and the uncertainty for banks in South Africa. Therefore, banks remain subject to legal uncertainty and associated risks. The issue of lender liability specifically with regard to the implication of “the person in control” requires clarification. Hence, it is recommended that legislation relevant to lender liability (National Environmental Management Act 107 of 1998; National Water Act 36 of 1998 and the National Environmental Management: Waste Act 59 of 2008) be revised to specifically accommodate and protect lenders (lending banks) in certain distinct circumstances. The role of banks is that of an intermediary between borrowers and lenders of money. Therefore, it influences the direction and pace of economic development and by default steers and promotes either sustainable or non-sustainable development. Currently, mainstream banks are in effect financing a brown economy and hence subscribe to a weak form of sustainability. It would seem that mainstream banks are more concerned with managing the impact that environmental risk may have on bank lending than the impact of bank lending on the environment. The evolving nature of sustainability (from weak to strong and from a brown to green economy) demands a fundamental policy change for banks. It is expected that mainstream banks will be put under even greater pressure than before to make the transition from weak to strong sustainability. Hence, banks’ current environmental risk management systems will not be sufficient to cater for new environmental risks and liabilities that the move to stronger sustainability (in the form of the green economy) will present. Banks should adopt the stronger version of sustainability; formulate environmental principles that the bank will adhere to; incorporate these environmental principles into all aspects of its lending cycle, develop an environmental risk management system that should include as a minimum the identification of all the applicable legislation pertaining to the specific financing or lending of capital, risk identification, assessment of the specific risk, implementation of risk control measures, mitigation of the risk, risk monitoring and auditing. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2014

In the environmental context banks face direct, indirect and reputational risks from their internal operations and their external business activities. The current specific focus on the protection of the environment makes it essential for banks and their directors to be aware and stay on top of potential risks and liabilities. This is especially so because banks’ directors can be criminally prosecuted for environmental crimes. The application and effect of the Prevention of Organised Crime Act 121 of 1998 (POCA) on persons convicted of an environmental crime or crimes has been identified as a possible new or added risk for banks and their directors. Banks in addition to their normal environmental risk and liabilities also need to contend with the possibility of lender liability. Existing legislation pertinent to lender liability does not expressly or specifically deal with lender liability. Absence of judgements on lender liability further exacerbates the risks and the uncertainty for banks in South Africa. Therefore, banks remain subject to legal uncertainty and associated risks. The issue of lender liability specifically with regard to the implication of “the person in control” requires clarification. Hence, it is recommended that legislation relevant to lender liability (National Environmental Management Act 107 of 1998; National Water Act 36 of 1998 and the National Environmental Management: Waste Act 59 of 2008) be revised to specifically accommodate and protect lenders (lending banks) in certain distinct circumstances. The role of banks is that of an intermediary between borrowers and lenders of money. Therefore, it influences the direction and pace of economic development and by default steers and promotes either sustainable or non-sustainable development. Currently, mainstream banks are in effect financing a brown economy and hence subscribe to a weak form of sustainability. It would seem that mainstream banks are more concerned with managing the impact that environmental risk may have on bank lending than the impact of bank lending on the environment. The evolving nature of sustainability (from weak to strong and from a brown to green economy) demands a fundamental policy change for banks. It is expected that mainstream banks will be put under even greater pressure than before to make the transition from weak to strong sustainability. Hence, banks’ current environmental risk management systems will not be sufficient to cater for new environmental risks and liabilities that the move to stronger sustainability (in the form of the green economy) will present. Banks should adopt the stronger version of sustainability; formulate environmental principles that the bank will adhere to; incorporate these environmental principles into all aspects of its lending cycle, develop an environmental risk management system that should include as a minimum the identification of all the applicable legislation pertaining to the specific financing or lending of capital, risk identification, assessment of the specific risk, implementation of risk control measures, mitigation of the risk, risk monitoring and auditing. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2014

Master´s thesis deals about problematic of fuzzy logic, fuzzy sets and operation with them. Also thesis describing procedure of quantification risks through fuzzy sets, process of fuzzyfication, defuzzyfication a theirs application in the expert systems FMEA and FMECA. Using selected chapters of czech states standards are established critical areas in building process, it is a chapters about quality, safety and environment. With these areas by using fuzzy sets theory are created the procentual input values in the decision program, created by Matlab. Output from program is decision how big the risk rate is and if is necessarily make corrective measures. A concrete example is the production of concrete goods, describing production process and composition of fresh concrete. A practical example, created by using information from real company, is a decision about the risk rate in the qualitative area.

Abstract in English, Afrikaans and Sesotho / Scuba diving is a popular marine recreational activity along the eastern and southern coast of Africa. This region is characterised as the East African Marine Ecoregion (EAME) and is known for its richness in marine fauna and flora, including some of the Indian Ocean‟s most diverse and abundant coral reef ecosystems, making it a popular destination for scuba divers. The future of the scuba diving industry has come under threat as a result of environmental, social, political and economic impacts, and there is a need to better understand how these external risks impact on scuba diving tourism businesses in the EAME. Empirical evidence suggests that external risks, both international and domestic, have an effect on the tourism industry as a whole. However, limited research has been conducted on the impact of such external risks on the dive tourism industry specifically. Existing research has also focused extensively on environmental risks rather than on how external risks of a political, economic and social nature affect dive operator sustainability in the EAME. Most studies have also focused on the demand side (divers) as opposed to the supply side (dive operators). In addition, as dive tourists have greater flexibility to change their destination should risks arise, this threatens the success of dive operators in higher risk areas. To address these problems, the primary objective of the research undertaken sought to comprehensively identify the impact of external risks (environmental, economic, social and political) on dive operators in four countries within the EAME from a supply-side perspective. In order to achieve the primary objective, the following secondary objectives were achieved: 1. Identified scuba diving tourism operators in the EAME and their scope of operation. 2. Determined the external risks most relevant to dive operators in the EAME and assessed their level of impact. 3. Compared the individual external risks experienced by each of the countries in the EAME (Kenya, Tanzania, Mozambique and South Africa) using a cross-case analysis. 4. Assessed the perception of dive operators regarding whether external risks would influence a dive tourists decision to travel to the dive operators area of operation in the EAME ii The study consisted of two phases. Phase 1 comprised structured interviews with a select group of dive operators to gain insight into the external risks most prevalent in the scuba diving industry, as well as to assist in developing a quantitative structured survey (Phase 2), which was subsequently completed by dive operators in Kenya, Tanzania, Mozambique and South Africa. Data was imported into SPSS for quantitative statistical analysis. From the primary data collected, the major findings from this study determined that current economic and political risks have the greatest impact on dive operators in the EAME, and this trend is expected to continue. Environmental degradation of coral reefs, while not seen as a threat at present, constitutes a key threat for the near future. The greatest influences expressed in terms of risk categories impacting on dive tourism are domestic economic risks, international economic risks, domestic political risks and international political risks. A cross-case analysis conducted on the four countries concluded that external risks have varying effects within the different countries. Finally, the results indicated that external risks significantly influence a dive tourist's decision to travel to the EAME. By identifying and assessing the external risks that have an impact on dive operators in the EAME, this research contributes to knowledge on the dive tourism industry in the EAME, as well as dive tourism further afield and the wider field of tourism management. The study's findings create awareness of the effect that external risks have on dive operators in the region. A conceptual framework was developed which encompasses external risks in the scuba diving industry. Risk radars, risk maps and colour-coded tables were further outputs this study which can assist businesses, society and economies in responding to current and future threats and crises in a more informative and intuitive way. This can be achieved by implementing risk management strategies to mitigate or reduce exposure to external risks; strengthening stakeholder involvement along the tourism value chain; and stressing the need for government involvement towards the protection of the environment and promotion of small business growth in the region. Future research can include a wider view of the marine tourism industry and other areas of the Blue Economy. / Skubaduik is 'n gewilde mariene ontspanningsaktiwiteit langs die oos- en suidkus van Afrika. Hierdie streek staan bekend as die Oos-Afrika Mariene Ekostreek (East African Marine Ecoregion, EAME) en is bekend vir sy rykheid aan mariene fauna en flora, insluitende sommige van die Indiese Oseaan se mees diverse en welige koraalrif-ekostelsels, wat dit 'n gewilde bestemming vir skubaduikers maak. Die toekoms van die skubaduikbedryf word bedreig weens die impak van omgewings-, sosiale, politieke en ekonomiese gebeure, en daar is 'n behoefte om beter te verstaan hoe hierdie eksterne risiko's skubaduiktoerisme-besighede in die EAME beïnvloed. Empiriese bewyse suggereer dat eksterne risiko's, internasionaal sowel as plaaslik, 'n invloed op die toerismebedryf as 'n geheel het. Beperkte navorsing is egter gedoen oor die impak van sulke eksterne risiko's op spesifiek die duiktoerisme-bedryf. Bestaande navorsing het ook uitvoerig gefokus op omgewingsrisiko's eerder as hoe eksterne risiko's van 'n politieke, ekonomiese en sosiale aard duik-operateur-volhoubaarheid in die EAME beïnvloed. Die meeste studies het ook gefokus op die aanvraagkant (duikers) in teenstelling met die aanbodkant (duik-operateurs). Verder, omdat duiktoeriste meer buigsaamheid het om hulle bestemming te verander indien risiko's voorkom, bedreig dit die sukses van duik-operateurs in hoë-risiko-gebiede. Om hierdie probleme te hanteer is die primêre doel van die navorsing wat gedoen is om op omvattende wyse die impak van eksterne risiko's (omgewing, ekonomies, sosiaal en polities) op duik-operateurs in vier lande in die EAME te identifiseer uit 'n aanbodkant-perspektief. Om die primêre doelwit te behaal, is die volgende sekondêre doelwitte bereik: 1. Skubaduik-toerisme-operateurs in die EAME en hulle operasionele omvang is geïdentifiseer. 2. Die eksterne risiko's wat die relevantste vir duik-operateurs in die EAME is, is bepaal en hulle vlak van impak is geassesseer. 3. Die individuele eksterne risiko's wat deur elkeen van die lande in die EAME (Kenia, Tanzanië, Mosambiek en Suid-Afrika) ervaar is, is vergelyk deur die gebruik van 'n kruisgeval-analise. 4. Die persepsie van duik-operateurs wat betref of eksterne risiko's 'n duiktoeris se besluit sal beïnvloed om na die duik-operateur se operasionele gebied in die EAME te reis, is geassesseer. Die studie het uit twee fases bestaan. Fase 1 het gestruktureerde onderhoude met 'n geselekteerde groep duik-operateurs behels om insig te kry in die eksterne risiko's wat die algemeenste in die skubaduikbedryf voorkom, en om te help om 'n kwantitatiewe gestruktureerde peiling (fase 2) te ontwikkel, wat gevolglik deur duik-operateurs in Kenia, Tanzanië, Mosambiek en Suid-Afrika voltooi is. Data is ingevoer in SPSS vir kwantitatiewe statistiese analise. Uit die primêre data wat ingesamel is, het die belangrikste bevindings van hierdie studie bepaal dat die huidige ekonomiese en politieke risiko's die grootste impak op duik-operateurs in die EAME het, en daar word verwag dat hierdie tendens sal voortduur. Die omgewingsagteruitgang van koraalriwwe, hoewel dit nie tans as 'n bedreiging beskou word nie, is 'n sleutelbedreiging vir die nabye toekoms. Die grootste invloede wat uitgedruk is as risiko-kategorieë wat 'n invloed op duiktoerisme het, is plaaslike ekonomiese risiko's, internasionale ekonomiese risiko's, plaaslike politieke risiko's en internasionale politieke risiko's. 'n Kruisgeval-analise wat op die vier lande uitgevoer is, het bevind dat eksterne risiko's wisselende uitwerkings binne die verskillende lande het. Laastens het die resultate aangedui dat eksterne risiko's 'n duiktoeris se besluit om na die EAME te reis, aansienlik beïnvloed. Deur die eksterne risiko's te identifiseer en te assesseer wat 'n impak op duik-operateurs in die EAME het, dra hierdie navorsing by tot kennis oor die duiktoerismebedryf in die EAME, asook duiktoerisme verder weg en die wyer veld van toerismebestuur. Die studie se bevindings skep 'n bewustheid van die uitwerking wat eksterne risiko's op duik-operateurs in die streek het. 'n Konseptuele raamwerk is ontwikkel wat eksterne risiko's in die skubaduikbedryf omvat. Risiko-radars, risiko-kaarte en tabelle wat volgens kleur gekodeer is, was verdere uitsette van hierdie studie wat besighede, die gemeenskap en ekonomieë kan help om te reageer op huidige en toekomstige bedreigings en krisisse op 'n meer ingeligte en intuïtiewe manier. Dit kan bereik word deur risikobestuurstrategieë te implementeer om blootstelling aan eksterne risiko's te mitigeer of te verminder; belanghebberbetrokkenheid op die toerismewaardeketting te versterk; en om die behoefte vir regeringsbetrokkenheid by die insluit. / Ho sesa tlasa metsi a lewatle ke mosebetsi o tsebahalang haholo wa boithabiso ba lewatle haufi le mabopo a ka botjhabela le borwa ba Afrika.
