Hazard Risk and Vulnerability Analysis (HRVA) of the city of Bhubaneswar (Odisha)” under the “GOI-UNDP Project entitled Enhancing Institutional and Community Resilience to Disasters and Climate Change

Objective: The main objective of the proposed multi-hazard risk and vulnerability analysis exercise is to assess the extent of risk and the vulnerabilities at the city level, i.e. Bhubaneswar City.  The outcome of the exercise is expected to help identify a set of structural and non-structural steps that City Administration and other stakeholders can take to mitigate the risks posed by various hazards. The scope of the exercise also includes the projected climate change scenarios (short term, medium term and long term) taking into account the past trends so that the recommended solutions and actions could be linked with the DM policy, sectoral planning and implementation of multi-hazard risk mitigation initiatives at community, ward and city  levels.

Component 1: Multi Hazard Mapping and Analysis  

• To identify and review relevant data sources to be used for conducting the hazard assessment in the study area, viz. all existing hazard maps of the study area, previous assessments i.e. research publications, local knowledge, socio-economic databases and survey materials that are already available.
• To visualize and establish climate change hazard scenarios (short term, medium term and long term) for the region based upon historical information on all major hazard  events over the past 100 years, in terms of its nature, geographical distribution, severity and frequency.
• To incorporate data from satellite imagery, aerial photographs and use GIS & other IT tools to clearly represent the consolidated data collected and show the results based upon analysis of various scenarios. In addition, incorporate information available with National and State Government agencies/other organizations.
• To provide adequate scientific analysis in respect of causation, frequency and magnitude while establishing their probabilities by using models.

Component 2: Development of Exposure Database at City level with resolution of ward level

• To develop the exposure database at City level.
• To remove erroneous errors from data and to present accuracy analysis

Component 3: Vulnerability Assessment ( Physical, Economic, Social and Environment)

• To conduct field assessment of physical vulnerability, which should include house types, critical infrastructure and lifelines (such as roads, power, communication, drainage and water supply system), and essential facilities such as schools, hospitals, and public buildings from the structural point of view. The structural analysis data should be further correlated with the level of compliance with the building regulations, which shall be covered by field survey/visits. A proper sampling method should be adopted before conducting the field survey.
• To conduct detailed assessment of economic vulnerability at the City level: This will include assessment of disaster impact on business, industries, residential, commercial, roads, handicrafts, and other sources of livelihoods in statistical and analytical terms. The assessment should also look at the impact on economy due to in and out migration in a city as a consequence of disaster within or outside city boundaries. The informal sector within the city should also be studied. New economic developments in the city, for example, growth of tourism, industries, and service sector, and its implications for natural resources and environment.
• To conduct detailed social vulnerability assessment: This will include the study of the population profile of the city, identification of the vulnerable groups and their level of access to basic services and livelihood. The assessment should also include vulnerabilities associated with gender, weaker sections, infants, children and the elderly, single parent families, women, widows, mentally and physically handicapped people, sick people, and other poor communities.
• To capture environmental vulnerabilities in the region and especially of the city. The implications of the population density for natural resources within the city limited, eg. availability of land, water, and tree cover.

Component 4: Risk Assessment

• To estimate economic/financial loss and damage; e.g. scenarios for loss to various categories/types of buildings, residential, industry, commercial, shelter, infrastructure and other facilities.  To correlate loss and damage data with the recent events.
• To identify potential risk based on climate change especially related to health sector.
• To identify high risk areas
• To develop a Risk Matrix
• To generate the mortality and injury scenarios including projections of potential losses to various sectors in different hazard zones.
• To estimate response and rehabilitation needs particularly focusing on people needing food, shelter, rescue/evacuation and first aid etc.
• To develop the risk atlas

Component 5: Capacity Assessment at institutional, community, ward and city levels

• Capture the capacities of existing government institutions, emergency service providers and social institutions at wards and city levels to manage risks.

Component 6: Recommended Actions that can be taken to incorporate multi-hazard related risks in DRR policy, sectoral planning and implementation for multi hazard t risk mitigation initiatives at community, wards and city  levels.
