Vulnerability as a multi-faceted phenomenon : a GIS-based data model for integrated development planning, environmental management and disaster risk reduction / Isak Dawid Jansen van Vuuren

Van Vuuren, Isak Dawid Jansen January 2015 (has links)
People and the surrounding environment are affected by development. In striving to improve their livelihoods, people have through their development activities and exploitation of natural resources contributed to the degradation of the environment. The environment is seen as the totality of the biosphere within which anthropological and ecological activities take place. These activities are influenced by forces of nature, and in some events referred to as hazards, which can cause disruption, injury and loss of life. This premise forms the basic concept of disaster, to which people and the environment react from a position of vulnerability. Vulnerability is multi-faceted construct that is primarily associated with social conditions. It relates to concepts of development planning and environmental management from a causal as well as a preventative perspective. Since disaster risk reduction has become the key focus of mankind’s reaction to disasters, the concept of vulnerability has also become a key focus for research, and has linked various research communities, particularly those involved in disaster risk management, climate change adaption and development research in a multi-disciplinary research environment. Socio-economic developments inspired mainly by the Second World War have since the 1940s focused research attention on development planning and disaster risk management. Hazards-based research made way for a focus on vulnerability research so as to reduce disaster risk. At the same time, an increased focus on development planning triggered a shift in philosophy away from a procedural rational planning approach to strategic, communicative planning. Disaster risk reduction along the lines of development planning has seen the emergence of a multi-disciplinary approach to vulnerability research. An apparent increase in disaster-related losses and environmental degradation has nonetheless changed people’s thoughts and alerted them to the unsustainability of the course of development. With the introduction of the Bruntland Report in 1987, the concept of sustainable development was introduced as a long-term environmental strategy. Sustainable development objectives have created a focus on the human–environment system and an understanding of relationships between anthropological and ecological entities. A special interest in spatial patterning and the geographic distribution of organisms has led to the development of landscape ecology as a study of spatial patterns and ecological processes. A need to capture environmental criteria in a computerised spatial database emerged in the 1960s, and gave rise to the development of geographic information systems (GIS) technology. GIS-based thinking about how the real world can be presented in various conceptualisations of data structures, led to the development of GIS science (GIScience). The latter was based on research by Michael Goodchild who seeks to redefine geographic concepts and their use in the context of geographic information systems. Hence GIS should be defined as a data-processing tool, as opposed to the popular view of a map-making tool. By approaching GIS from an information system perspective that includes the development of conceptual, logical and physical data models, a platform is provided for the integration of spatial-based disciplines such as development planning, environmental management and disaster risk management. A synthesis of the theoretical foundation of these three disciplines shows commonalities in terms of a multi-disciplinary approach, as well as a concern for the environment and for social upliftment based on sustainable development principles. They also share a strong spatial orientation, which provides for GIS technology to serve as an entry point for the integration of these disciplines. The aim of the current research was therefore to develop a GIS-based data model that would address the landscape-based relationships between spatial entities from a database design point of view. The model is founded on the principles of database design, specifically the concept of entity-relationship modelling. It also incorporates basic Boolean logic to identify the functioning of an entity in its landscape setting as either acceptable or unacceptable. This concept supports the analysis of environmental sensitivity and disaster risk from the level of small geographic units, thereby enabling vulnerability reduction efforts at a local scale. The research in hand was useful to define and investigate the theoretical grounding of development management, environmental management, disaster risk reduction and geographic information systems, as well as to identify their common focus areas. An analysis of GIS technology and the development of a data model provided a focus on database development as the key for providing an information-based entry point and integration of development management, environmental management, disaster risk management. A case study for an area near Richards Bay, where development affected a wetland by increased vulnerability to flooding, has proven the GIS-based data model to be valuable as a tool that can be implemented to reduce vulnerability through informed and improved planning practices. / PhD (Development and Management), North-West University, Potchefstroom Campus. 2015

A conceptual framework for disaster risk participatory communication for at-risk communities in South African municipalities / Tigere Chagutah

Chagutah, Tigere January 2014 (has links)
South Africa, like many other developing countries, faces a growing problem of informal settlements which are mushrooming in and around the major urban centres. Living conditions within these settlements are typically poor with residents facing a range of basic livelihoods challenges, exacerbated by poverty, inequality and social exclusion. Unplanned and rapid urbanisation, from which informal settlements originate, and existing conditions in these areas, heighten risk to disaster and provide the conditions that turn natural and man-made events into major livelihoods disruptions. The most devastating of these disruptions are disasters brought on by uncontrolled fires, extreme wet weather and associated flooding. To forestall disaster, minimise livelihoods disruptions and debilitating loss of assets, and safeguard developmental progress, local governments have increasingly adopted risk reduction approaches to their development planning and implementation. Among some of the critical risk reduction measures adopted is the deployment of communication interventions meant to cultivate a culture of risk avoidance among at-risk communities. While it is largely accepted that developmental losses can be considerably reduced if people are properly educated and well-prepared for a disaster, it is also widely recognised that current tools and guidelines for communication of disaster risk in developing communities have largely proved inadequate. Among leading criticisms is that the communication interventions implemented neither fully cater for the contemporary proactive and pre-emptive (risk minimising) approach to disaster risk management nor the developmental imperatives of the disaster risk reduction paradigm. This study, therefore, sought to propose a conceptual framework for the reorientation of thinking and improvement of the on-the-ground practice of disaster risk communication in South African municipalities, and to ensure, among other things, that the practice of disaster risk communication in South Africa places participation of at-risk communities at the centre of communication interventions for disaster risk reduction. A literature study was conducted to explore what principles of the participatory approach to development communication could be applicable to a framework for disaster risk communication interventions. Following the literature study, an empirical study into the contemporary disaster risk communication practice in the three study sites of Cape Town, George and uThungulu District was carried out. The field study comprised semi-structured interviews with disaster risk communication managers and other key informants, and focus group discussions with members of informally settled communities in the study areas. Using a hybrid thematic analytic approach, the data gathered empirically were analysed against the salient themes derived from the literature study and those emerging as the empirical study progressed, and from that process a conceptual framework for disaster risk participatory communication for at-risk communities in South African municipalities was developed and proposed. In conclusion, guidance was also given for translation of the conceptual framework into actual practice by disaster risk managers and other disaster risk reduction role-players in South Africa. / PhD (Communication Studies), North-West University, Potchefstroom Campus, 2014

Fenologia da dispersão e estratégias de germinação de sementes de plantas lenhosas e herbáceas no Cerrado /

Escobar, Diego Fernando Escobar. January 2019 (has links)
Orientador: Leonor Patrícia Cerdeira Morellato / Resumo: A germinação de sementes e estabelecimento de plântulas são as etapas iniciais e cruciais do ciclo de vida das plantas, sendo importantes determinantes dos padrões de distribuição, diversidade e dinâmica das comunidades vegetais. Nos ecossistemas sazonais, a disponibilidade de água no solo e a heterogeneidade do ambiente são os principais fatores limitantes da germinação e estabelecimento das plântulas. Nestes ambientes a fenologia da dispersão das sementes, o nicho de germinação e a dormência devem sincronizar a germinação com o início da estação chuvosa, o que maximiza o período favorável ao estabelecimento, incrementando as chances de sobrevivência das plântulas à subsequente estação seca. Por outro lado, as plantas respondem à heterogeneidade ambiental distribuindo a progênie através do espaço ou do tempo. Distribuir as sementes ao longo de diferentes áreas aumenta a chance de que pelo menos uma parte delas chegue a lugares adequados para a germinação e estabelecimento das plântulas. Por outro lado, a dormência incrementa a variação do tempo de germinação distribuindo a germinação em vários eventos, o que diminui a probabilidade de que todas as plântulas morram devido a eventos imprevisíveis. Os estudos dos mecanismos que sincronizam a germinação com o início da estação chuvosa nos ambientes tropicais sazonais não levam em consideração o nicho de germinação nem a história evolutiva das espécies, e estão focados majoritariamente nos ecossistemas florestais. Portanto, não t...

In seasonal environments, water availability in the soil and environmental heterogeneity are the main factors that limit seed germination and seedling establishment. In these environments, seed dispersal season, germination niche, and dormancy synchronize germination with the onset of the rainy season, which maximizes the favorable period for seedling establishment and increases the chances of seedlings surviving the subsequent dry season. Plants respond to environmental heterogeneity by distributing germination through space and time. Distributing seeds throughout different areas (spatial dispersal) increases the chances that at least some will arrive in sites adequate for germination and establishment. On the other hand, dormancy increases the variation in germination time, distributing germination into multiple reproductive events (temporal dispersal), thus decreasing the likelihood that all seedlings die due to unpredictable events. However, most studies addressing the mechanisms that synchronize germination with the onset of the rainy season in seasonal tropical environments do not consider germination niche or species evolutionary history and are mainly focused on forest ecosystems. Therefore, a clear understanding on the relative importance of the mechanisms contro... (Complete abstract click electronic access below) / Doutor

Risco de câncer e comportamentos preventivos: a persuasão como uma estratégia de intervenção / Cancer risk and preventive behaviors: persuasion as an intervention strategy

Tonani, Marcela 11 September 2007 (has links)
O câncer configura-se como um problema de saúde pública e seu controle depende essencialmente de ações nas áreas da promoção da saúde, proteção específica e do diagnóstico precoce da doença. A efetividade das intervenções designadas para seu controle pode contar com o auxílio do processo de persuasão empregado. O presente estudo buscou avaliar o grau de risco para apresentação de câncer contemplando os fatores de risco pertinentes, bem como, avaliar a presença e as características da persuasão na comunicação para prevenção e detecção precoce de câncer. Trata-se de um estudo observacional, com caráter transversal, onde foram empregados dois instrumentos para o alcance dos objetivos; a população abordada foi de um bairro da cidade de Ribeirão Preto/SP. Constatou-se que os altos riscos foram para os cânceres de cólon/reto, cérvico e de endométrio; e moderados riscos para estes acrescidos de pulmão e mama. Quanto à persuasão, observou-se que houve o desencadeamento das informações acerca do câncer, no entanto estas não conseguiram manter-se efetivas por longos períodos; também não se identificou o reforço dessas informações. Portanto, diante do risco de câncer e dos comportamentos preventivos levantados, considera-se que a persuasão é uma estratégia útil para diminuição desses riscos e, de incentivo e manutenção de comportamentos preventivos; porém, ela deve conter todas as etapas do processo a fim de que não se perca a oportunidade de gerar comportamentos preventivos ou de detecção precoce. / The cancer is configured as a problem of public health and its control depends essentially on action in the areas of the promotion of the health, specific protection and of the precocious diagnosis of the illness. The effectiveness of interventions assigned for its control can count with auxiliare of the process of persuasion employed. This study aims to evaluate the risk level of developing cancer, considering the pertinent risk factors, and the presence of persuasion and characteristics in the communication regarding cancer prevention and early detection. It is an observational study, conducted on 110 inhabitants of a neighborhood in the city of Ribeirao Preto, Sao Paulo, Brazil. It was confirmed there are high risks for colon/rectum, cervical, and endometrial cancer; and moderate risks for these and also lung and breast cancer. In terms of persuasion, it was observed that cancer information was spread but was not sustained for long periods. Moreover, there was no reinforcement. In view of cancer risk and the identified preventive behaviors, persuasion is considered a useful strategy to reduce these risks as well as to encourage and sustain preventive behaviors, however it must contain all the stages of these process for doesn\'t lose the chance to develope preventive behaviors or precocious detection.

Transparency in information about health

Bodemer, Nicolai 21 December 2012 (has links)
Diese Dissertation umfasst vier Manuskripte zum Thema Risikokommunikation und medizinischen Entscheidungen. Das erste Manuskript diskutiert Unterschiede, Gemeinsamkeiten und die Anwendbarkeit von drei zentralen Ansätzen, die helfen sollen, bessere Entscheidungen zu treffen (Nudging, Social Marketing, Empowerment). Das zweite Manuskript präsentiert Ergebnisse einer Medienanalyse zur Evaluation von Zeitungs- und Internetberichten in Deutschland und Spanien über die HPV-Impfung. Basierend auf vordefinierten Standards für transparente, vollständige und korrekte Risikokommunikation, deckt die Medienanalyse Schwächen in der Berichterstattung auf. Das dritte Manuskript untersucht wie Laien relative Risikoreduktionen bzw. –erhöhungen, ein Standardformt in der Medizin, verstehen. Beide Formate führen Laien und Experten in die Irre und führen zur Überschätzung der tatsächlichen Effekte. Ein diskutierter Ausweg ist die zusätzliche Kommunikation der Basisrate. Die Ergebnisse zeigen, dass das Verständnis von relativen Risikoreduktionen (-erhöhungen) mit Basisrate von dem Präsentationsformat (Prozent- vs. Häufigkeitsformat) und der individuellen Fähigkeit im Zahlenverständnis abhängt. Teilnehmer mit geringem Zahlenverständnis profitierten von der Darstellung in Häufigkeiten; Teilnehmer mit hohem Zahlenverständnis zeigen ein besseres Verständnis unabhängig des Formats. Dennoch—selbst mit Basisrate—missverstehen viele Teilnehmer die Risikoinformation. Das vierte Manuskript untersucht wie Teilnehmer Behandlungen unter Unsicherheit auswählen. Ein Einwand gegen die Kommunikation von Unsicherheit ist die Behauptung, dass Menschen Unsicherheit in Gewinnsituationen vermeiden, in Verlustsituationen dagegen suchen. Die Ergebnisse dieser Studie in Bezug auf die Auswahl von medizinischen Behandlungen konnten diese Annahmen nicht bestätigen. Darüber hinaus wählte die Mehrheit der Teilnehmer die gleiche Behandlung, wenngleich sich die zugrundeliegende Auswahlstrategie unterschied. / This dissertation comprises four manuscripts focusing on health risk communication and medical decision making. The first manuscript discusses differences, commonalities, and the applicability of three major approaches to help patients make better decisions: nudging, social marketing, and empowerment. The second manuscript presents results of an evaluation of media coverage about the HPV vaccine of newspaper and Internet reports in Germany and Spain. Based on predefined standards for transparent, complete, and correct risk communication, the analysis revealed substantial shortcomings in how the media informed the public. The third manuscript centers on a standard format to communicate treatment benefits and harms: relative risk reductions and increases. Such formats have been found to misinform and mislead patients and health professionals. One suggestion is to always include information about baseline risk to reduce misunderstandings. Results show that even when baseline risk was communicated, it depended on the presentation format (percentage vs. frequency) and people’s numeracy skills whether they correctly interpreted the risk reduction (or increase). Low numerates benefited from a frequency format, whereas high numerates performed better independent of the format. Yet, a substantial proportion of participants still misunderstood the meaning of a relative risk reduction (or increase). The fourth manuscript investigated how laypeople choose between medical treatments when ambiguity is present. One objection against communicating ambiguity is the claim that laypeople are ambiguity averse in the domain of gains and ambiguity seeking in the domain of losses. Results did not find supporting evidence for this claim in medical treatment choice. Moreover, most participants selected the same treatment option, independent of numeracy. However, the underlying choice strategies varied between individuals.

Cenários de ocupação urbana e seus impactos no ciclo hidrológico na bacia do córrego do Mineirinho / Scenarios of urban occupation and its hydrologic impacts in the Mineirinho river basin

Benini, Rubens de Miranda 01 September 2005 (has links)
Este trabalho teve por objetivo principal estabelecer e comparar diferentes cenários de ocupação urbana e seus efeitos no ciclo hidrológico. Buscou-se avaliar os riscos de enchentes à jusante, causados pelo crescimento urbano e aumento das áreas de impermeabilização que ocorrerão com a implantação do novo campus da USP – São Carlos – SP e a conseqüente ocupação da bacia devido à especulação imobiliária. Dessa forma, a bacia do córrego do Alto Mineirinho foi dividida em sub-bacias, utilizando a abordagem de bacias embutidas. Foram estudados 4 cenários de ocupação urbana: cenário pré-urbanização (1972); cenário atual (2000), cenário 2025 com plano diretor (CPD) que inclui recuperação ambiental; e cenário 2025 sem plano diretor (SPD). Foram necessárias aerofotografias para demarcação do uso e ocupação do solo. Além disso, esse trabalho iniciou o monitoramento experimental de parâmetros hidrológicos e ambientais. Para avaliação e comparação dos diferentes cenários realizaram-se simulações hidrológicas com uso do modelo hidrológico IPH II. Com as análises hidrológicas foi possível verificar que a bacia, com apenas 18,6 % de urbanização (2000), apresenta qualidade hídrica inferior à recomendada para os corpos d’água classe 2 (CONAMA 357/05). Em relação às simulações hidrológicas, pôde-se observar que no cenário 2025 SPD, a vazão máxima cresceu 388,0 % quando comparada ao cenário 1972 e 319,4 % quando comparada ao cenário 2000. Entre os cenários 2025 CPD e 2025 SPD há diminuição de 22,3 % na vazão máxima e o aumento no tempo de pico é de 50 minutos. Porém, os riscos de enchente, analisados pelo método de curvas de permanência, mostraram-se que mesmo com aplicação de diretrizes do PD os riscos de inundações continuam altos, o que indica a necessidade de integrar medidas estruturais e medidas não-estruturais para amenizar os efeitos de enchentes à jusante / This work aims to establish and to compare different scenarios of urban occupation and its hydrologic effects. It evaluates downstream flood risks caused from upstream urban growth increased due to impervious areas and housing speculation surrounding the implantation of the new campus of University of Sao Paulo in Sao Carlos city, SP. The Mineirinho river basin was studied through nested sub-basin approach. Four scenarios of urban occupation have been depicted: pre-urbanization (year 1972), current situation (year 2000), prospective scenario with master plan (until year 2025; CPD), and expected situation without master plan (until year 2025; SPD). Aerial photos were used to help on the evolution of land occupation between past and current situation. The comparison of different scenarios was outlined with use of hydrologic model IPH II. Moreover, this work set the monitoring and record of hydrologic time series. Through experimental analyses it was verified that with 18,6 % of urban areas the water quality of sub-basins decreased significantly. Hydrologic modeling simulations showed that maximum streamflow discharges of scenario 2025 SPD would rise up to 388,0 % higher than scenario 1972 and 319,4 % higher than scenario 2000 respectively. Maximum stream discharges and peak timing of scenario with master plan of year 2025 (CPD) would have respectively a reduction of 22,3 % and a increase of 50 minutes in comparison to scenario without master plan of year 2025 (SPD). Permanency curves revealed with the application of master plan guidelines flood risks however continue high, thereby pointing the needs of integrate structural and non-structural measures to cope with floods downstream

An integrated national disaster risk reduction and climate change adaptation development investment framework for Barbados, a Small Island Developing State (SIDS)

Greenidge, Nicole January 2018 (has links)
Disasters and climate change threaten the very existence of a special group of developing states- Small Island Developing States (SIDS). This research tackles the problem of limited uptake of integrated approaches to address risk in practice- in particular through disaster risk reduction (DRR) and climate change adaptation (CCA). The benefits of these approaches are so significant that they can be considered to be investments in development. Focusing on Barbados, a SIDS, this research therefore seeks to identify the prospects for establishing an integrated disaster risk reduction and climate change adaptation (DRR-CCA) development decision-making framework. It also seeks to understand the policy implications for other SIDS. In addressing the research problem, a risk governance framework and mixed methods approach is proposed for identifying the prospects for DRR-CCA. This allows for the challenges and the potential in actor networks, institutions, and the various dimensions of risk decision-making to be identified. The specific SIDS DRR-CCA risk governance framework utilised to generate the prospects is identified from literature. Data from documents, surveys and in-depth semi-structured interviews with 30 representatives from 20 organisations operating at different levels were gathered on DRR and CCA risk governance in Barbados from November, 2014 to May 2015. Analysis was carried out using document analysis, thematic analysis; social network analysis, and descriptive statistics. The research identifies that SIDS require an enhanced risk governance framework for DRR-CCA. This framework has a systemic approach at the core, as well as an explicit development approach supported by a joined-up governance approach. Furthermore, risk assessments should include assessments of adaptive capacity. Existing potential for DRR-CCA risk governance was identified in highly dense networks, established disaster management networks, and a unique polycentric network that engages intraregional partners in national governance. Notwithstanding, challenges related to cohesion within and across institutions and sectors; missing community and socio-economic participation; as well as issues connected to unadjusted mind-sets to address the DRR paradigm shift in practice, and limited development-socio-ecological systems approaches, meant that the prospects identified mainly addressed these shortcomings. A spatial methodology for DRR-CCA seemed feasible. This research contributes a framework for conceptualising DRR-CCA risk governance in SIDS which could be applicable to others. It offers a Caribbean SIDS perspective and practical suggestions for DRR-CCA that are relevant to SIDS practitioners and donors. Further research should focus on testing the prospects across the varying governance contexts of SIDS.

Using computer visualisations to educate and communicate volcanic hazards to at-risk communities

Mani, Lara January 2018 (has links)
With an increase in the number of people living in proximity to active volcanic centres worldwide, there is a greater need to provide effective and engaging education and outreach programmes to reduce vulnerability and prepare exposed communities for potential future volcanic eruptions. The finalisation of the Sendai Framework (UNISDR, 2015a) has also cemented the need for disaster risk managers to engage at-risk communities with education and outreach programmes, to reduce the number of deaths and injuries caused by volcanic eruptions worldwide. Education and outreach programmes are already commonplace for disaster risk reduction, with many taking the form of traditional presentations, maps, diagrams, TV and radio broadcasts. In recent years, there has been a shift towards the use of more creative media to communicate volcanic hazards and engage populations in outreach activities. These have included films, comic strips, puppet shows, board games and video games. However, to-date there is little empirical evidence for the use of these media with at-risk communities. This research seeks to address this issue by providing evidence for the effective use of creative media for volcanic hazard education by adopting the use of video games (or serious games). To assess how effective serious games could be as an education tool, a bespoke video game (St. Vincent’s Volcano) was developed collaborative with disaster risk agencies and communities on the Eastern Caribbean island of St. Vincent and then trialled with adults and students from across the island. A range of outreach sessions were adopted to compare and contrast the applications of the game and to identify the most effective method of its delivery. These sessions included a traditional outreach presentation used as a control, and a group of UK students for a cohort comparison. Data were collected through a mixed-methods approach. Overall the results of the study demonstrate how successful the game can be as an education tool, promoting knowledge improvement in players. The results also demonstrate how the role of the outreach instructor is important to encourage engagement and can result in higher levels of overall positive engagement exhibited by the students. The game was also successful at promoting knowledge gain and engagement with adult participants. The results also demonstrated promise for games in promoting longer-term knowledge retention and for improving awareness of existing outreach materials. This research provides a foundation for the increased integration of emerging technologies within traditional education sessions. The work also shares some of the challenges and lessons learnt throughout the development and testing processes and provides recommendations for researchers looking to pursue a similar study or to adopt the use of serious games.

A l'ombre du géant aigre-doux. Vulnérabilités, capacités et réduction des risques en contexte multiethnique : le cas de a région du Mont Kanlaon (Philippines) / Non communiqué

Cadag, Jake Rom David 10 December 2013 (has links)
Les groupes ethniques minoritaires sont parmi les secteurs de la société qui sont menacés en permanence par des risques plus élevés de catastrophes. Le fondement d'un tel constat est les impacts négatifs disproportionnés de catastrophes passées. Il est de ce fait nécessaire d'intégrer tous les groupes ethniques en particuliers les minorités dans la réduction des risques de catastrophe (RRC). Pourtant, la communauté scientifique a peu étudié le rôle de l’ethnicité dans la vulnérabilité et la capacité des populations exposées à divers aléas. Ainsi les praticiens sur le terrain et les organisations non-gouvernementales (ONG), ne possèdent pas de méthodes et d’outils appropriés pour intégrer les minorités ethniques dans la RRC. En plus, des exemples de méthodologies et de politiques visant à rendre cet objectif opérationnel et institutionnalisés sont également limités. Cette étude vise à répondre à ces lacunes, en prenant l’exemple des communautés multiethniques autour de Mont Kanlaon situé sur l'île de Negros aux Philippines. La zone d'étude se caractérise par une grande diversité ethnique composé d'au moins trois grands groupes ethniques (Ilonggos, Cebuanos et Bukidnons). Les résultats de cette étude suggèrent que cette mosaïque constitue une dimension importante de la RRC puisque chaque groupe ethnique possède ses propres formes de vulnérabilité et de capacité face aux aléas volcaniques et d’autres origines. Ces minorités ethniques sont parmi les secteurs les plus vulnérables de la société philippine en raison de leur statut marginalisés. En outre, les résultats de cette étude suggèrent que chaque groupe ethnique possède des capacités issues en grande partie de ressources locales qui sont utiles aux fins de la RRC. / The ethnic minority groups are among the sectors of the society who are permanently threatened by higher risk of disasters. The basis of such claim is the disproportionate negative impacts of both major and minor disasters. There is thus a pressing need to integrate ethnic minority groups in disaster risk reduction (DRR). However, within the scientific community, there are limited studies in the current literature of disaster that investigated the role of ethnicity in shaping the vulnerability and capacity of the ethnic groups. The authorities, non-government organizations (NGOs), and researchers have limited defined methods and tools to make such as objective operational in the field. Finally, plans, actions and policies to make such objective institutionalized are also limited. This study aimed to fulfill those gaps. The study has adapted an integrated DRR framework and a methodology that follows the ideals and principles of Community-Based Disaster Risk Reduction (CBDRR). The present study focuses on the multiethnic communities surrounding Mt. Kanlaon located in the island of Negros, Philippines. The study area is characterized by a great ethnic diversity composed of at least three major ethnic groups (Ilonggos, Cebuanos, and Bukidnons). The results of the study suggest that this ethnic mosaic constituted a major dimension of DRR because each ethnic group portrays different vulnerabilities and capacities in the face of volcanic hazards and other natural hazards. These ethnic minorities are among the most vulnerable sectors of the Philippine society due to their marginalized and minority status. In addition, the results of this study also suggest that each ethnic group possesses capacities derived from local resources that are useful for the purpose of DRR.
