Purpose The purpose of this paper is to illustrate practical approaches to addressing issues of risk reduction and disaster prevention in urban areas. In addition to exposure to natural hazards, urban areas represent complex risks and vulnerabilities together with complicated governance structures. Design/methodology/approach To address the challenge, SEEDS mobilised a “Disaster Watch Forum” – a citizens’ platform that brought citizens together to proactively engage with the local government. With hand-holding support from SEEDS, training by domain experts, internal team building and the forum has become a credible people-based institution addressing issues of risk reduction and prevention. Findings Urban risk reduction has remained a challenging issue with solutions often sought in high investment structural interventions. These have limited impact on the urban poor living in informal areas. This paper reveals “bottom-up” people-based approach that is able to engage with the “system” from “outside”. It reveals how people relate to day-to-day risks that affect their lives, making it the stepping stone to address higher order societal risks. Finally, the immense power and energy of youth and children work as local “agents of change”. Overall, the work aligns with priorities of the Sendai Framework for Disaster Risk Reduction. Research limitations/implications There are three principal implications for further research: with half the world now urbanized, urgent solutions are needed for improving disaster risk governance in cities; taking a “whole of society” approach in addressing a wider canvas of risks; and redirecting investments in urban areas towards managing risks, rather than managing disasters. Practical implications The model illustrated is replicable in urban areas facing risk. It worked well in a population catchment of 50,000 residents; to achieve scale would require enabling a federated structure of several localised forums. Originality/value The paper presents a hands-on experience in building an alternative approach to urban risk reduction. It has required authors to move from “government to governance” model making citizens active stakeholders in proactively addressing their own underlying vulnerabilities that lead to creation of and exacerbation of risks.

It has been more than a decade after 5.9 SR earthquakes hit one of the most destructed area Tembi Hamlet, Bantul District, Yogyakarta Province. Amidst the wreaking havoc, the area gained its resilient in no time. This research, aimed to 1) explore what are the factors influential towards local resilient, especially micro-small-medium enterprises; and 2) analyze strategies to tackle disaster. It employed mix method, while the key questions were developed using “Sustainable Livelihood Approach” by DFID, geared with “Pentagram Asset” mapping for each spatial and temporal unit. The result revealed that 1) the micro-small-medium enterprises in urban area are resilient towards earthquake due to fair physical, natural and financial assets management and abundant social, human and political assets. These assets have created enabling environment towards behavioral change of urban society; 2) Despite various livelihood strategies existed in urban areas, the research highlighted three types of livelihood strategies within disaster risk management perspective, i.e. survival (disaster), consolidation by no-change plan mechanism and accumulation strategies by change plan mechanism (post disaster). Critically, pentagram assessment is able to identify feasible local assets and activities, however it left the policy, institution, interaction and multi sector aspects from the spotlight. Herewith, the research proposes evaluation scan to rethinking sustainable livelihood approach within disaster risk management by adding these aspects into the observation. It also revealed that local autonomous initiatives to extend urban based economic activities and supported by abundant political interest play pivotal role in disaster management at developing countries.

Abstract Tsunamis are disasters with unpredictable events, but the occurrence of tsunamis in Indonesia always has a significant impact on every sector of life, especially the economy and society. The position of the Indonesian State, which is located in the subduction zones as well as the increasing human activity in coastal areas, are the factors that trigger the tsunami, which is accompanied by losses and damages. One of them is Purworejo Regency, which is directly adjacent to the Indian Ocean. Vulnerability assessment is the focus of this paper. This study uses a quantitative analysis approach with analytical methods in the form of scoring analysis. Weighted cell-based data processing is the main cog in vulnerability assessment. The combination of economic and social parameters creates a vulnerability. Financial vulnerability is measured based on GRDP and productive land, while social vulnerability is estimated based on population density and vulnerable communities. The vulnerability analysis results are in the form of total vulnerability level in the medium class, the level of economic vulnerability in the low, quality, and social vulnerability in the medium class associated with the implication of disaster risk management.

The flooding of the Chao Phraya River in Thailand and the Great East Japan Earthquake and Tsunami, both of which occurred in 2011, reminded us of the risks of business disruption and further impacts on national, regional, and global economies through supply chains when disasters occur anywhere in the world. Considering the increasing economic losses attributable to disasters, the fourth session of the Global Platform for Disaster Risk Reduction (2013) aimed to promote resilience and foster new opportunities for public-private partnerships as part of an overall approach to improving risk governance. Furthermore, it highlighted that a growing world requires a new approach to development action, emphasizing the private sector&rquo;s role in managing disaster risks. One of the most significant private sector contributions to disaster risk management is the creation of the business continuity plan/planning (BCP) and business continuity management (BCM) systems, which were standardized as ISO22301 and disseminated in many business enterprises around the world. However, a BCP or BCM system has been neither formulated for nor implemented in most local enterprises in industry agglomerated areas, even though these are located in areas vulnerable to disasters. Moreover, in the case of large-scale disasters, a business enterprise’s capacity may be too limited to mitigate damages and maintain operations through its own efforts, even if BCPs are prepared. The main reason for this is the disruption of public infrastructure and services. In order to minimize the negative economic impacts or economic losses, particularly in the case of a large-scale disaster that disrupts the fundamental infrastructure in certain areas, it is important to conduct risk assessment on a proper scale and to prepare scenario-based disaster management plans for area-wide damage mitigation. In addition, it is essential to have integrated resource management and strategic recovery plans to support each enterprise&rquo;s BCM actions in coordination with public sector activities. Considering this backgrounds, the Japan International Cooperation Agency (JICA) and the ASEAN Coordination Center for Humanitarian Assistance on Disaster Management (AHA Center) launched the “Natural Disaster Risk Assessment and Area Business Continuity Plan Formulation for Industrial Agglomerated Areas in the ASEAN Region” project in February 2013. The project introduced the new concept of the Area BCP, which, based on a risk assessment of the area, designates a framework and direction for coordinated damage mitigation measures and recovery actions by stakeholders, including individual enterprises, industrial area managers, local authorities, and infrastructure administrators, to allow business continuation of the industrial area as a whole. The project also established Area BCM as a cyclic process of risk assessment, sharing risk and impact information, determining a common strategy of risk management, developing the Area BCP, implementing and monitoring the planned actions to continuously improve the Area BCM system, and coordinating among stakeholders, in order to improve the capability for effective business continuity of the area. This paper aims to evaluate the progress of the project and to explore lessons from the applied process of Area BCM and its benefits.

Rapid increase in population and growing concentration of capital in urban areas has escalated both the severity and longer-term impact of natural disasters. As a result, Disaster Risk Management (DRM) and reduction have been gaining increasing importance for urban areas. Remote sensing plays a key role in providing information for urban DRM analysis due to its agile data acquisition, synoptic perspective, growing range of data types, and instrument sophistication, as well as low cost. As a consequence numerous methods have been developed to extract information for various phases of DRM analysis. However, given the diverse information needs, only few of the parameters of interest are extracted directly, while the majority have to be elicited indirectly using proxies. This paper provides a comprehensive review of the proxies developed for two risk elements typically associated with pre-disaster situations (vulnerability and resilience), and two post-disaster elements (damage and recovery), while focusing on urban DRM. The proxies were reviewed in the context of four main environments and their corresponding sub-categories: built-up (buildings, transport, and others), economic (macro, regional and urban economics, and logistics), social (services and infrastructures, and socio-economic status), and natural. All environments and the corresponding proxies are discussed and analyzed in terms of their reliability and sufficiency in comprehensively addressing the selected DRM assessments. We highlight strength and identify gaps and limitations in current proxies, including inconsistencies in terminology for indirect measurements. We present a systematic overview for each group of the reviewed proxies that could simplify cross-fertilization across different DRM domains and may assist the further development of methods. While systemizing examples from the wider remote sensing domain and insights from social and economic sciences, we suggest a direction for developing new proxies, also potentially suitable for capturing functional recovery.

This paper analyses how disaster risk management paradigms have gradually developed since the 1960s, shaped by practical experience of-and the debate about-the rising number of disasters, growing urbanization, and changing climatic conditions. In this context, climate change is shown as driving an urban pro-poor adaptation agenda, which could allow current shortcomings in urban risk reduction to be overcome. However, as past lessons in disaster risk management are rarely considered, any potential for improvement remains untapped. Possible ways of rectifying this situation are discussed, and a comprehensive framework for the reduction of both disaster and climate risks is presented.
