- Description: This study investigates the temporal, spatial and impact characteristics of severe convective storm hazard and risk in the Eastern Cape Province of South Africa. Using historical data on severe convective storms dating from 1897, patterns of the hazard threat and risk to various geographic populations were investigated. A conceptual framework that emphasises the combined role hazard and vulnerability play in defining risk was used for the study. A methodology for ranking the severity of the storms in the historical dataset, based on recorded damage/impact, was specifically developed for the study. It is intended that this methodology will have a potentially wider application and may be adapted to a range of hazard impact and risk studies in South Africa and internationally. The study was undertaken within the context of the South African Disaster Management Act of 2002. Findings of the study show that severe convective storms can occur throughout the province, but there are clearly demarcated areas of higher frequency and concentration. The impact of storms is particularly severe on impoverished and vulnerable rural populations in the eastern parts of the province, where there is an urgent need for building capacity in disaster risk management. A major outcome of the study is the production of a severe convective storm hazard/risk map of the Eastern Cape, which it is hoped will be of benefit to a number of stakeholders in the province, particularly disaster management, but also the South African Weather Service, agricultural organisations, development/planning authorities, educational authorities and risk insurers. It is hoped that this map and the study in general will assist in guiding the operational responses of the various authorities, especially in terms of those interventions aimed at disaster risk reduction in the Eastern Cape.

- Description: Hazards are an integral part of people-environment relationships. The impact of hazards locally and globally has become increasinglymore severe. particularly in the previous two decades. This is largely as a result of unwise human intervention in natural systems. The study of hazards at secondary school level affords valuable opportunities for learning about people-environment issues. This in turn, can promote a greater awareness of environmental problems. One of the most important current aims of Geographical Education is the development of critical thinking skills in pupils. Such skills are vital for equipping pupils with the necessary tools to understand and participate in solving the world's increasing human and environmental problems. The development of a critical faculty in pupils is best achieved by the use of learner-based participatory teaching strategies where pupils are involved in problem solving activities. Research has shown that British and South African Geography curricula reflect current thinking in Geographical education and learning theory. The 1992 Junior Secondary Geography Syllabus in line with these trends. includes a section for study on hazards. Hazards are presented primarily as case studies in modern Geographical texts. which is seen as one of the most effective ways of teaching hazards. Research however suggests that South African textbooks have certain shortcomings. notwithstanding the importance placed on textbooks by teachers in this country. This study investigated the extent to which case study teaching materials on hazards are optimising opportunities available for effective learning within an Environmental Paradigm. An evaluation methodology, which is believed to have value for use by other researchers, was developed to suit the specific requirements of the study. The study findings reveal a poor realisation of the current aims of Geographical Education and learning theory, regarding the South African teaching materials. Recommendations are made improvements in the development and use of local case teaching materials. Guidelines for the development of for study local materials are provided from case studies in British texts and from methods developed by the researcher.
