A new approach to crisis communication<\/h4>\r\nAt the heart of the solution is the recognition that real-time, accurate information is the most valuable resource during an emergency. Researcher for FinEst Centre for Smart Cities<\/a> Dr. Luiza Schuch de Azambuja<\/a> and Tenured associate professor Wolfgang Dieter Gerstlberger<\/a> from TalTech emphasize that traditional crisis response methods are often slow and unidirectional. Governments and municipalities issue warnings, but the flow of information from affected communities back to authorities remains limited. The new resilience toolkit seeks to bridge this gap by facilitating both bottom-up and top-down communication. \u201cThe idea is to have a platform that integrates the communication coming from the city to the citizens and also from the citizens to the city. During emergencies, accurate information about what\u2019s happening and where to go is crucial,\u201c Azambuja states.\r\n\r\nUnlike traditional early warning systems that rely primarily on government-issued alerts, this toolkit incorporates real-time data from multiple sources, including sensors and community reports. This ensures that emergency response teams and decision-makers receive a holistic and dynamic view of unfolding crises, significantly reducing reaction times.\r\n

Beyond flooding: a comprehensive resilience toolkit<\/h4>\r\n[caption id=\"attachment_11535\" align=\"alignright\" width=\"320\"]\"Wolfgang Wolfgang Dieter Gerstlberger[\/caption]\r\n\r\nAlthough initially focused on floods, the project has expanded to encompass a variety of natural hazards. In Estonia, for example, heavy snowstorms often block roads and disrupt logistics, while in Brazil, extreme floods pose life-threatening risks. The modular nature of the toolkit ensures that it can be scaled and adapted to different geographical and climatic conditions.\r\n\r\n\u201cWe need to find a modular way to address different risks. A small city in Eastern Europe will have different needs compared to a major urban center in Brazil or Germany. Yet, all of them require a more efficient response mechanism,\u201c says Gerstlberger.\r\n\r\nA key aspect of this adaptability is the ability to integrate with existing local solutions. In Porto Alegre, Brazil, for instance, an existing municipal app already serves as an emergency communication tool. Instead of replacing it, the toolkit can be embedded within the existing infrastructure, ensuring seamless accessibility. In cities without a dedicated emergency app, the platform can function independently through a browser-based system.","image":null,"align":""},{"acf_fc_layout":"text","type":"text","text":"

Harnessing the power of data and community intelligence<\/h4>\r\nThe toolkit integrates data from multiple sources, including sensors that monitor water levels and weather conditions, as well as citizen reports from affected areas. The use of community intelligence (CCI \u2013 Collaborative and Community Intelligence) allows for a more dynamic response. Residents in affected zones can submit real-time updates, such as flood levels or blocked roads, which are then validated through geolocation and multimedia evidence. \u201cPeople on the ground often have valuable information before official warnings are issued. By engaging the community, we can improve situational awareness and decision-making,\u201c Azambuja explains.\r\n

\"People on the ground often have valuable information before official warnings are issued. By engaging the community, we can improve situational awareness and decision-making.\"<\/p>\r\n<\/blockquote>\r\nThis decentralized approach could significantly reduce response time in emergencies. As seen in the devastating floods in Spain and France last year, delays in communication can have fatal consequences. \u201cIt always takes too long. The idea is to speed up the process and use all available data sources to inform citizens and authorities in real-time.\u201c\r\n\r\nDeveloping and implementing this solution is not without its challenges. The project must integrate multiple layers of data, including sensor measurements, crowd-sourced reports, and existing governmental databases. Ensuring data accuracy, privacy, and cybersecurity is another major hurdle.\r\n\r\nAdditionally, the social aspect of disaster preparedness is critical. In Porto Alegre, for instance, last year\u2019s catastrophic flood was unprecedented, leaving many residents unprepared. \u201cPeople didn\u2019t believe the official warnings, and many refused to evacuate,\u201d recalls Azambuja. \u201cRaising awareness and training communities on how to respond is just as important as the technology itself.\u201d","image":null,"align":""},{"acf_fc_layout":"image","image":11543},{"acf_fc_layout":"text","type":"text","text":"

Making the solution sustainable<\/h4>\r\nThe long-term success of the resilience toolkit depends on a viable business model. Various funding avenues are being explored, including subscriptions, donations, and advertisements. Municipalities are expected to be key clients, but financial constraints vary widely. While wealthier cities such as Hamburg may allocate significant budgets for disaster preparedness, smaller municipalities in Brazil may require governmental or international support.\r\n\r\nInsurance companies and urban planners could also benefit from the system\u2019s predictive analytics and risk assessment capabilities. As natural disasters result in billions of euros in damages annually, insurers may find value in accessing more precise risk data.\r\n\r\nThe project is currently in the validation phase, with ongoing discussions with pilot cities\u2014Haapsalu and Kuressaare in Estonia, and Porto Alegre in Brazil\u2014to tailor the solution to their specific needs. Researchers are conducting interviews with stakeholders, rescue teams, and municipalities worldwide, including potential partners in Indonesia and Germany.\r\n\r\nAs climate change continues to exacerbate the frequency and severity of natural hazards, cities must adopt more intelligent and adaptable crisis management solutions. The Natural Hazard Resilience Toolkit offers a data-driven, community-powered approach that enhances both preparedness and response. By integrating sensor technology, social media intelligence, and local community engagement, this project represents a promising step toward a safer, more resilient future for cities worldwide.\r\n\r\nAs Professor Gerstlberger aptly puts it, \u201cIt\u2019s not about reinventing the wheel\u2014it\u2019s about making it turn faster and more effectively when disasters strike.\u201d\r\n

Comment \u2014 Kairi Niit, Head of the Environmental Department at Saaremaa Municipality Government:<\/h4>\r\n\"A thorough analysis<\/a> was conducted at the national level to map flood risk areas, and Saaremaa Municipality was involved in the process. This information has also been incorporated into the preparation of Saaremaa\u2019s comprehensive spatial plan.\r\n\r\nNational efforts have paid less attention to the flood risks posed by inland water bodies \u2014 a rise in sea level and periods of high water can cause significant flooding from the P\u00f5duste and Tori rivers in the town of Kuressaare. The nature of the challenges depends on the causes and accompanying factors of the flooding, such as storms, heavy rainfall, snowmelt surges, ice conditions, and resulting issues with accessibility, restoring power outages, and ensuring the delivery of essential services.\"\r\n

Gunnar Havi, Crisis Preparedness Advisor at Saaremaa Municipality Government:<\/h4>\r\n\"In terms of flooding, inland water bodies don\u2019t cause us much concern by themselves. Rather, a high sea level can reverse the flow of the Tori and P\u00f5duste rivers. We have taken into account the areas where the water level could rise by up to two meters.\r\n\r\nCurrently, the main method for data collection is visual observation. Water level gauges exist in the harbors of Kuressaare, but they are also monitored visually, and the municipality doesn\u2019t use any sensors or other devices to issue alerts. Rising water levels are assessed based on weather forecasts provided by the Estonian Environment Agency.\r\n\r\nCrisis management processes are in place, and in general, there are no issues with collecting or sharing information. Since parts of Kuressaare are located within the flood risk area (2 m rise), people monitor water levels closely themselves, but certain sensors might offer a better overview.\r\n\r\nThe main expectation for the solution being developed is that the information is timely and allows for action to be taken. If the installed devices and sensors can improve crisis management processes even further, then that would be a success.\"","image":null,"align":""},{"acf_fc_layout":"text","type":"text","text":"***\r\n\r\nSix finalists have been selected for the fourth round of the FinEst Centre for Smart Cities\u2019s Smart City Challenge 2024<\/a>.
