WED1.6: Risk in urban areas
Understanding and Measuring Urban Resilience: A new UN-Habitat's initiative
UN-Habitat, Nairobi, Kenya
The cost of urban disasters during 2011 alone is estimated at over $380 billion with the largest impacts felt in Christchurch, New Zealand; Sendai Province in Japan, and Bangkok and environs. The social and economic impact on these cities was not only felt within the immediate areas, but also nationally and globally. With 50% of the world’s population already in cities and substantial projected urban population increases over the coming decades, the rationale for new tools and approaches that strengthen the capacity of local administrations and citizens to better protect human, economic and natural assets of our towns and cities is strong.
Preliminary study of the relationship between new risk factors and traditional risk factors.
1State Key Laboratory of Earth Surface Processes and Resource Ecology of Beijing Normal University, China; 2Key Laboratory of Environmental Change and Natural Disaster of Ministry of Education, Beijing Normal University, China; 3Academy of Disaster Reduction and Emergency Management of Ministry of Civil Affairs and Ministry of Education, Beijing Normal University, China
Traditional risk factors fall into four categories: natural disasters, public health, accidents during production and social security. The four types of risks are called as public safety issues by the government of China . Each category of the four risk factors includes a large number of risk elements. New risk factors are the ones that are connected to human with our discoveries and more attention to them, which is called locking risk.
Vulnerability assessment of urban building stock: a hierarchic approach
1University of Aveiro, Portugal; 2University of Coimbra, Portugal
In the last decades the evaluation of the seismic risk, just as other natural phenomenon’s, are of rising concern, considered essential in the activity and definition of strategy planning and urban management. The evaluation of the seismic vulnerability of the existent building stock in the perspective of the seismic risk mitigation should not be placed only in relation to the isolated buildings of relevant historical and cultural importance, but also, in relation to the agglomerate of buildings in urban centres. The chronological construction process frequently results in characteristic heterogeneity of masonry and wall connection quality. In addition, buildings do not constitute independent units given that they share the mid-walls with adjacent buildings and the façade walls are aligned. This way, as post-seismic observations proved, buildings do not have an independent structural behaviour, but they interact amongst themselves, mainly for horizontal actions and so the structural performance should be studied at the level of the aggregate and not only for each isolated building. In most cases, for masonry structures there is no need for sophisticated dynamic analyses for seismic resistance verification or vulnerability assessment. This is even more relevant when an assessment at the level of a city centre is pursued. In this work, the results of evaluation of the vulnerability will be presented in accordance to three proposed methodologies based on a vulnerability index that consequently allows the evaluation of damage and creation of loss scenarios (economical and human) not only at the level of the building and its façade walls but also at the level of the aggregates. It will be discussed and evaluated the application of the referred methodologies and its integration in an SIG platform.
Enhancing urban resilience to extreme waters: The WASH and RESCUE Initiative
1Stockholm Environment Institute, Sweden, Kingdom of; 2Kristianstad City, Sweden
Human beings today are increasingly urbanites. At the same time, human health and security in urban areas are increasingly under threat from extreme water conditions (e.g. floods and droughts) that are projected to become much more frequent with changing climate. One of the major challenge areas for adapting our growing cities to the extreme climatic variations is the sectoral and fragmented approaches through which cities are planned and developed. To a large extent, it seems that the cross-scale linkages are neglected, and the disjuncture between knowledge and action remains a major barrier for genuine progress toward resilient cities.

Building a safe municipality Morelia, Michoacàn, Méxiko
1Institute for Research on Risk Management. INIGER .Morelia,México; 2The Municipality of Morelia, Michoacán.
Physiographically the municipality of Morelia, Michoacán, México is located in the south central axis of the neovolcanic zone, creating the presence of different geological and hidrometeorological hazards. In this paper will be presented the results of public policies, which were generated from the incorporation of the risk management process as a core element in the planning of development for the municipality of Morelia. The first section refers to the methodologies, models and procedures for the evaluation of threats and vulnerabilities and risk maps. The second part provides a summary from the analysis of indicators of risk management according to the criteria of the (BID), evaluated at the municipal level. And in the last section, is presented a summary of public policy development to contribute to the construction of a safe municipality
Experiences of working for improving state of community based disaster preparedness in Mumbai city
Program Director - United Way India Helpline - United Way of India & United Way Mumbai Helpline- United Way of Mumbai
This presentation will highlight the strategies for improving the level of resilience in urban communities based on the experiences gained in Mumbai city. United Way Mumbai Helpline (UWMH), a special initiative of United Way of Mumbai over the past 6 years has been striving to improve the state of community based disaster preparedness in Mumbai city through public private partnership initiatives. Interventions of UWMH focus on channelizing the disparate efforts of public and private stakeholders, creation of on-ground network of stakeholders equipped with know-how for disaster management and thereby complementing the government in disaster management. The key strategies include; firstly; Multi-Stakeholder Partnership wherein, key government and private stakeholders are engaged in process of disaster preparedness at local civic ward level, inter-agency interaction is facilitated for collective disaster response i.e. role identification, resource sharing and collaboration and capacity building of all the stakeholders by channelizing locally available expertise. Secondly; Bridging the gap between government and community by mobilizing community participation: information dissemination, preventive education, emergency communications, community mapping thorough community participation: anticipated threats, available resources and plans for matching them for disaster mitigation. Thirdly; Creating on-ground network of trained community volunteers: train various stakeholder groups: college youth, school & college teachers, citizens, corporate employees, government employees as First Responders and link them with local municipal officials. Fourthly; Community Resilience Indicators: UWMH actively contributed for developing indicators for assessing the level of community’s resilience and necessary actions under the initiative of the Municipal Corporation of Greater Mumbai. Fifthly; Post Disaster Recovery: Relief & Rehabilitation: Immediate relief and long-term rehabilitation of disaster victims for faster recovery through Coporate Partnerships. Thorough need assessment in consultation with government and local NGOs to avoid duplication and benefit right people. Thus, the learnings are useful for replication in other mega cities for creating a resilient world.
