Disaster Risk Reduction (DRR) Education from Social Disciplinary Theoretical Perspectives

Disaster is a social phenomenon. The occurrence and impacts of disasters including the education sector can be studied through a social problem lens. This paper draws meaning and understanding of DRR education using the sociological disciplinary framework in a detailed qualitative case study of three schools as they responded to the devastating Gorakha earthquake in 2015 and other disasters in Nepal. This paper considers the three sub-disciplines of sociology: the sociology of disaster, the sociology of education and the sociology of education governance in a development context. These sub-disciplines are nested together to analyse social, political and historical factors and their relationships which are helpful to identify risks and vulnerabilities in the education sector in Nepal. These are the major areas to explore the disaster context and needs of context-specific education acts (hereafter DRR education) to minimise the potential risks of disasters. The article concludes that the social disciplinary framework is significantly useful to analyse DRR education provisions and implications of education governance to mobilise school in disaster preparedness, response and recovery.

An international program on Silk Road Disaster Risk Reduction--a Belt and Road initiative (2016-2020)

Belt and Road Initiative(BRI) is a Chinese national strategy which calls for cooperative economic, political and cultural exchange at the global level along the ancient Silk Road. The overwhelming natural hazards located along the belt and road bring great challenges to the success of BRI. In this framework, a 5-year international program was launched to address issues related to hazards assessment and disaster risk reduction(DRR). The first workshop of this program was held in Beijing with international experts from over 15 countries. Risk conditions on Belt and Road Countries(BRCs) have been shared and science and technology advancements on DRR have been disseminated during the workshop. Under this program, six task forces have been setup to carry out collaborative research works and three prioritized study areas have been established. This workshop announced the launching of this program which involved partners from different countries including Pakistan, Nepal, Russia, Italy, United Kingdom, Sri Lanka and Tajikistan. The program adopted the objectives of Sendai Framework for Disaster Risk Reduction 2015-2030 and United Nation Sustainable Development Goals 2030 and was implemented to assess disaster risk in BRCs and to propose suitable measures for disaster control which can be appropriate both for an individual country and for specific sites. This paper deals with the outcomes of the workshop and points out opportunities for the near future international cooperation on this matter.

Disaster risk reduction in mountain areas: an initial overview on seeking pathways to global sustainability

As disasters cripple the world’s prospects for sustainable development, protecting the most vulnerable groups exposed to hazards is one of the main challenges facing humanity. Owing to the systemic nature of risk and the interactions and interdependencies between upland and lowland systems, healthy and productive mountain households and livelihoods are essential to global sustainability. This paper argues that, building on existing international frameworks, and integrated knowledge and praxis, the development of a global policy agenda should be established to build sustainable peace, sustainable security, and development.

A catastrophic debris flow in the Wenchuan Earthquake area,July 2013：characteristics,formation,and risk reduction

In the Wenchuan Earthquake area,many co-seismic landslides formed blocking-dams in debris flow channels. This blocking and bursting of landslide dams amplifies the debris flow scale and results in severe catastrophes. The catastrophic debris flow that occurred in Qipan gully(Wenchuan,Southwest China) on July 11,2013 was caused by intense rainfall and upstream cascading bursting of landslide dams. To gain an understanding of the processes of dam bursting and subsequent debris flow scale amplification effect,we attempted to estimate the bursting debris flow peak discharges along the main gully and analyzed the scale amplification process. The results showed that the antecedent and triggering rainfalls for 11 July debris flow event were 88.0 mm and 21.6 mm,respectively. The event highlights the fact that lower rainfall intensity can trigger debris flows after the earthquake. Calculations of the debris flow peak discharge showed that the peak discharges after the dams-bursting were 1.17–1.69 times greater than the upstream peak discharge. The peak discharge at the gully outlet reached 2553 m^3/s which was amplified by 4.76 times in comparison with the initial peak discharge in the upstream. To mitigate debris flow disasters,a new drainage channel with a trapezoidal V-shaped cross section was proposed. The characteristic lengths(h1 and h2) under optimal hydraulic conditions were calculated as 4.50 m and 0.90 m,respectively.

Landslide Hazard and Community-based Risk Reduction Effort in Karanganyar and the Surrounding Area,Central Java,Indonesia

Karanganyar and the surrounding area are situated in a dynamic volcanic arc region, where landslide frequently occurs during the rainy season. The rain-induced landslide disasters have been resulting in 65 fatalities and a substantial socioeconomical loss in last December 2007. Again, in early February 2009, 6 more people died, hundreds of people temporary evacuated and tens of houses damaged due to the rain-induced landslide. Accordingly, inter-disciplinary approach for geological, geotechnical and social investigations were undertaken with the goal for improving community resilience in the landslide vulnerable villages. Landslide hazard mapping and communitybased landslide mitigation were conducted to reduce the risk of landslides. The hazard mapping was carried out based on the susceptibility assessment with respect to the conditions of slope inclination, types and engineering properties of lithology/soil as well as the types of landuse. All of those parameters were analyzed by applying weighing and scoring system which were calculated by semi qualitative approach (Analytical Hierarchical Process). It was found that the weathered andesitic-steep slope (steeper than 30o) was identified as the highest susceptible slope for rapid landslide, whilst the gentle colluvial slope with inter-stratification of tuffaceous clay-silt was found to be the susceptible slope for creeping. Finally, a programme for landslide risk reduction and control were developed with special emphasize on community-based landslide mitigation and early warning system. It should be highlighted that the social approach needs to be properly addressed in order to guarantee the effectiveness of landslide risk reduction.

Effectiveness of Drought Risk Reduction Policies: Case Study of Hay Production in Kajiado County, Kenya

Kenya has integrated several international, continental, and regional strategies and policies into its national and county programs to address climate-related disasters in livestock systems in pastoralism. This study reviews how these policy instruments have been integrated into local laws and the viability of hay production, a drought risk reduction strategy. The methodology used was a desktop review of policies, a KAP survey using a quantitative and qualitative questionnaire on 354 pastoralists and key informants selected using stratified random sampling, and a cost-benefit analysis of 23 hay farms in Kajiado-Central sub-county. The findings established that Kenya had adopted adequate legal instruments to support disasters in general and droughts specifically. However, the strategies are not elaborated into practical guidance resulting in poor implementation. For instance, the flagship hay production project in Kajiado focuses on building infrastructure on the government farms, with little support going to the actual hay farmers. In addition, staffing levels of technical officers are too low to adequately translate the strategies into activities that address the hay farmer’s pain points, namely the lack of a stable hay market, expensive capital assets and machinery, lack of quality forage seeds, and extension education. This paper recommends reviewing the implementation of the ongoing hay flagship projects to address the hay enterprise’s profitability and elaborating the strategies down to guidance that can be easily rolled out cognizant of the low staffing levels. Public-private partnerships can also address some challenges by stabilizing the hay markets, providing storage, and maintaining good-quality hay. In addition, the strategic feed reserve should include hay for pastoral livestock systems under drought risk reduction programs. Thus, targeted, relevant projects are critical if private hay enterprises are a sustainable drought risk reduction strategy.

Disaster Risk Reduction and Management: Recalling the Need for Paradigm Shift in Definition

The paper articulates the need for a paradigm shift in defining the basis of what constitutes a disaster. This new framework must be sensitive to the need for a more theoretical approach to inform disaster and hazard management. Central to this is that the resulting approach cannot be muddled in linear rational and procedural doctrines but appreciate the dynamics of complex nonlinearity of disaster events. By engaging in thought experiment and critical analysis of existing literature, the paper deconstructs the normative paradigm of defining disaster. The end is to inform disaster management and risk reduction intervention and mitigation programmes. The presented alternative approach is sensitive of the need to equally include;spatial, political, social, parameters. These are appreciated as being equally important as those dealing with ecological and economic. The resulting not only include other elements, but also expands the definition to the complex conditions inherent in the origin of phenomena to the interaction of the phenomena with multiple and complex socio-spatial and demographic dynamics, and then appreciating the complex results of this nonlinear interaction. The need for a more substantive definition of disaster underlines the pre-analysis that is necessary for implementation of mitigation and prevention strategies. That disasters are becoming more complex is synonymous with the complexities inherent in post-war development dynamics.

Pesticide Risk Reduction of Vegetable Farmers: A Case Study in Vietnam

A survey was carried out on farmers cultivating vegetables in Gia Lam district, Hanoi city, Vietnam to investigate their practice in reducing pesticide risks in their farming. Pesticides were an important input in the production there, but the risks of pesticides in recent years had been insignificant. Research results showed that the majority of farmers had relatively well implemented various solutions to reduce pesticides risks in their production, including actively using alternative pest management (IPM) solutions, using biological pesticides, using pesticides properly according to the 4-right pesticide use principle, using labour protection while spraying, and applying treatment measures after spraying. The study suggested solutions to reduce and avoid pesticide risks.

Improving risk reduction potential of weather index insurance by spatially downscaling gridded climate data-a machine learning approach

Open-access gridded climate products have been suggested as a potential source of data for index insurance design and operation in data-limited regions.However,index insurance requires climate data with long historical records,global geographical coverage and fine spatial resolution at the same time,which is nearly impossible to satisfy,especially with open-access data.In this paper,we spatially downscaled gridded climate data(precipitation,temperature,and soil moisture)in coarse spatial resolution with globally available longterm historical records to finer spatial resolution,using satellite-based data and machine learning algorithms.We then investigated the effect of index insurance contracts based on downscaled climate data for hedging spring wheat yield.This study employed countylevel spring wheat yield data between 1982 and 2018 from 56 counties overall in Kazakhstan and Mongolia.The results showed that in the majority of cases(70%),hedging effectiveness of index insurances increases when climate data is spatially downscaled with a machine learning approach.These improvements are statistically significant(p≤0.05).Among other climate data,more improvements in hedging effectiveness were observed when the insurance design was based on downscaled temperature and precipitation data.Overall,this study highlights the reasonability and benefits of downscaling climate data for insurance design and operation.

Disaster Risk Reduction,Climate Change Adaptation and Their Linkages with Sustainable Development over the Past 30 Years:AReview

The severe damage and impacts caused by extreme events in a changing climate will not only make the sustainable development goals difficult to achieve,but also erode the hard-won development gains of the past.This article reviews the major impacts and challenges of disaster and climate change risks on sustainable development,and summarizes the courses and linkages of disaster risk reduction(DRR),climate change adaptation(CCA),and sustainable development over the past 30 years.Our findings show that the conceptual development of DRR actions has gone through three general phases:disaster management in the 1990s,risk management in the 2000s,and resilient management and development in the 2010s.Gradually,CCA has been widely implemented to overcome the adverse effects of climate change.A framework is proposed for tackling climate change and disaster risks in the context of resilient,sustainable development,indicating that CCA is not a subset of DRR while they have similarities and differences in their scope and emphasis.It is crucial to transform governance mechanisms at different levels,so as to integrate CCA and DRR to reduce disaster and climate change risks,and achieve safe growth and a resilient future in the era of the Anthropocene.

Big Earth data for disaster risk reduction

In an ever-changing world,where the frequency and intensity of natural and humanmade disasters are on the rise,disaster risk reduction has emerged as a crucial focal point of interdisciplinary research,governance,and public discourse.Disaster risk reduction,which aims to safeguard humans and protect environments from hazards and threats,is of high societal relevance and closely related to several of the United Nations Sustainable Development Goals(SDGs).The findings from research into disaster risk reduction contribute significantly to making cities and other settlements more inclusive,safe,resilient,and sustainable.

Digitalization in Disaster Risk Reduction:The Use of Smartphones to Enhance the Safety of Informal Settlements in Iringa,Tanzania

Housing in informal settlements often lacks construction techniques that adopt criteria of resilience to natural hazards.Smartphones are rapidly diffusing in economically developing countries.The aim of this study was to assess the current use of smartphones by the masons of the informal settlements of Iringa,Tanzania,and to identify pathways for improving their construction practices.Data were collected through a mixed method approach that includes in-depth interviews,surveys,and a focus group with masons.The results reveal that only a few masons received formal training,most of them have never interacted with a qualified engineer nor consulted trained professionals when needed.Most masons own a smartphone and they extensively use it to gather technical information from the web,transfer money through mobile payments,share images of construction details,and promote their work on social media.The broad use of smartphones shows potential for enhancing construction quality.This article presents a unique analysis of the use of smartphones in the construction of informal settlements in Tanzania,which could be extended to other countries.Based on the findings,new strategies are proposed to engage with local stakeholders and foster the exchange of technical knowledge for safer settlements via smartphones.

Cost-Benefit Analysis of the Wuxikou Integrated Flood Management Project Considering the Effects of Flood Risk Reduction and Resettlement

Evaluation of the economic costs and benefits of flood disaster risk management projects is crucial.However,current costbenefit analyses(CBA) often lack reliable estimates of the expected loss reduction from flood control measures and ignore quantitative assessments of resettlement.To address these limitations,this study incorporated a probabilistic risk analysis method and quantitative resettlement benefits assessment into the CBA framework,using the Wuxikou Integrated Flood Management Project(WIFMP) in Jiangxi Province,China,as a case study.The direct economic benefits of flood control were estimated by integrating hydrological statistics,numerical flood inundation simulation,and quantitative damage analysis with exposure and vulnerability data.Furthermore,the resettlement benefits were quantified by measuring the annual income growth of migrants based on assumptions about household employment.Our analysis shows that the total WIFMP investment is RMB 3546.1 million yuan(USD 1=RMB 6.976 yuan),including loan principal and interest of 244.4 million yuan,and operations and maintenance of 605.5 million yuan at 2020 prices.Annual project benefits are estimated at 351.3 million yuan in flood risk reduction,155.7-191.9 million yuan from increased resettlement income,and 42.7 million yuan in power and water revenues.Considering the costs and benefits across the entire project lifecycle,the internal rate of return ranges from 13.7 to 14.2%,and the net present value ranges from 31.8 to 352.6 billion yuan.Through improved benefit estimation methodology,this research enables a more reliable and holistic evaluation of costs and benefits for flood risk management projects.It provides insights for policymakers and practitioners involved in similar projects,contributing to more informed decision making and better allocation of resources in flood disaster risk management.

Financing Disaster Risk Reduction:Exploring the Opportunities,Challenges,and Threats Within the Southern African Development Community Region

The Southern African Development Community(SADC)region,a regional economic body comprised of 16 member states,is one of our planet's most vulnerable regions to natural hazards,and has a complex disaster risk profile.The region has sustained several disasters over the past decades.These events include annual floods in 2004-2019 and extreme droughts(1990-1993);other climate-induced disasters,such as cyclones,also have had devastating impacts,particularly on the Indian Ocean island states and east coast countries.To reduce the risk and impacts of dis asters,governments must invest in disaster risk reduction(DRR).However,interventions aimed at reducing social and economic vulnerability and investing in longterm mitigation activities are often few,poorly funded,and insignificant in comparison with money spent on humanitarian assistance,dis aster relief,and post-disaster reconstruction.This study investigated whether DRR is adequately funded within SADC member states in light of the high stakes in human life,infrastructure,and economic losses and the potential savings involved.The study applied a qualitative research design with data collected through semistructured interviews and focus group discussions.Respondents were selected purposefully and through snowball sampling with a total of 67 respondents from Botswana,Eswatini,Namibia,South Africa,and Zimbabwe participating in the study.The study findings reveal that DRR is inadequately funded in all the member states consulted in comparison to funding allocated to disaster response.In light of the underfunding experienced by DRR activities,this study provides a platform for lobbying and advocacy for adequate funding for DRR.

Bangkok to Sendai and Beyond: Implications for Disaster Risk Reduction in Asia

The recently concluded World Conference on Disaster Risk Reduction(WCDRR) in Sendai, Japan and the Sendai Framework for Disaster Risk Reduction2015–2030(SFDRR) have set renewed priorities for disaster risk reduction(DRR) for the next 15 years. Due to Asia’s high exposure to natural hazards, the implications of the new SFDRR have major significance for the future development of the region. The 6th Asian Ministerial Conference on Disaster Risk Reduction(AMCDRR), held in Bangkok in 2014, was a regional preparatory meeting for the WCDRR, and proposed various targets and indicators for DRR in Asia. The AMCDRR recommended inclusion of these goals in the SFDRR. This study focuses on the WCDRR negotiations, particularly outcomes that affect four major groups: local authorities; children and youth;science and technology; and business and industry. An analysis is undertaken of the overlaps and gaps in the outcomes of the 6th AMCDRR and other preceding conferences that fed into the WCDRR. A set of recommendations has evolved from this examination for consideration at the upcoming 7th AMCDRR in 2016. The areas that merit consideration in the upcoming AMCDRR2016 are:(1) development of baseline data and quantitative indicators for monitoring progress in DRR;(2) creation of a common stakeholder platform;(3) construction of city typologies for consideration in all future local level planning;(4) promotion of a culture of safety by linking large enterprises with small and medium enterprises; and(5) exchange and sharing of information and databases between regions at all scales.

The Sendai Framework for Disaster Risk Reduction and Persons with Disabilities

In this paper, the Sendai Framework for Disaster Risk Reduction 2015–2030(SFDRR) is evaluated with respect to its ramifications for persons with disabilities. In the SFDRR, persons with disabilities were referenced either directly or indirectly as part of the preamble,the guiding principles, the priorities for action, and the role of stakeholders. In addition, the 2015 World Conference on Disaster Risk Reduction, during which the SFDRR was adopted, incorporated explicit recommendations toward a disability-accessible and inclusive environment not evident in previous disaster risk reduction conferences. The infusion of disability-related terms and concepts such as accessibility, inclusion, and universal design throughout the SFDRR document was significant. These concepts,which have their origin in disability studies, are used in the SFDRR document to refer to the needs of all in disaster,not only to people with disabilities. These disability-related concepts will now serve the field of disaster risk reduction as important overarching disaster-related principles. The authors conclude that the SFDRR has firmly established people with disabilities and their advocacy organizations as legitimate stakeholders and actors in the design and implementation of international disaster risk reduction policies.

Thirty Years of Science,Technology,and Academia in Disaster Risk Reduction and Emerging Responsibilities

The 1990 initiation of the International Decade for Natural Disaster Reduction marked its 30th year in 2019.The three decades since then have seen significant developments in science and technology and their incorporation into the decision making in the field of disaster risk reduction.The disasters that have occurred during that time have enhanced the importance of the field,and new research and innovations have evolved.This article summarizes this evolution through the review of specific milestones.While the Sendai Framework for Disaster Risk Reduction 2015–2030 provides opportunities for synergies with the sustainable development agenda,the science and technology communities have also changed their roles from advisory to co-designing and co-delivering solutions.Higher education plays an important role in developing new generations of professionals,and the role of thematic incubation in higher education institutions is highlighted along with the development of the professional society in disaster risk reduction.The evolution from Society 4.0(information age)to Society 5.0 will see an enhanced role of the technology-driven approach in disaster risk reduction,while traditional knowledge and indigenous technologies still remain valid for society.Scientists and science communities need to be more sensitive to changing the“last mile”concept to“first mile”thinking with respect to the users’needs and perspectives.

Science and Technology Networks: A Helping Hand to Boost Implementation of the Sendai Framework for Disaster Risk Reduction 2015–2030?

The Sendai Framework for Disaster Risk Reduction 2015–2030 underlines the importance of Science and Technology(S&T) and S&T networks for effective disaster risk reduction(DRR). The knowledge of existing S&T networks and their exact role in DRR,however, is limited. This opinion piece initiates a discussion on the role of S&T networks in the implementation of the Sendai Framework. The article highlights that current practice is oriented towards a narrative that emphasizes the potential of S&T for DRR and stresses a collaborative approach delivered through networks. But a true understanding of whether and how S&T networks can mobilize and enable S&T for DRR is missing. We call for a review of existing S&T networks for DRR and the development of good practice guidelines on S&T networks for DRR. This review should include knowledge on how to overcome common challenges and maximize the benefits, along with a framework for successful evaluation of such networks.This knowledge would provide much needed guidance for existing and emerging networks.

Human Mobility in the Sendai Framework for Disaster Risk Reduction

This article looks at how population movements are addressed by the Sendai Framework for Disaster Risk Reduction 2015–2030(SFDRR), and highlights some of the potential implications of the SFDRR on disaster risk reduction(DRR) and mobility management work. The article looks at the operational implications of the SFDRR text and covers issues of including migrants in DRR work;informing urban development about current and future mobility trends; managing relocations, evacuations, and displacement to prevent future risks and reduce existing ones; and preparing for and managing disaster-induced population movements to reduce the direct and indirect impacts of natural hazards. Overall, the references to human mobility within the SFDRR show an evolution in the way the issue is considered within global policy dialogues. Both the potential of population movements to produce risk and their role in strengthening the resilience of people and communities are now clearly recognized. This is an evolution of previously prevailing views of mobility as the consequence of disasters or as a driver of risk. While some implications of the DRR-mobility nexus might still be missing from DRR policy, population movements are now recognized as a key global risk dynamic.
