AI Chatbots: New lifeline for floods, landslides and climate emergenciesBy T.D.C. Pushpakumara, Senior Lecturer, 成人头条 and Prof. Fazeela Jamel Asan,Professor , University of ColomboSri Lanka has always lived in close relationship with nature its monsoons, tropical storms, and lushhill country. Yet in recent decades, the scale and speed of natural disasters have changed. Climatechange has altered rainfall patterns, causing intense cloudbursts, flash floods, prolongeddroughts, and sudden landslides in areas that were once considered safe. Communities thatpreviously enjoyed predictable seasonal weather now face uncertainty almost every month. Insuch an environment, the ability to communicate fast, accurate, and understandable disasterinformation is no longer a convenience it is a life-saving necessity.Despite this urgent need, many Sri Lankans still do not receive timely warnings duringemergencies. The country芒鈧劉s disaster-management agencies such as the Department ofMeteorology, NBRO, the Irrigation Department, and District Disaster Management Centres collectvast amounts of real-time hazard data. They track rainfall, river levels, landslide risk, reservoirinflows, and storm movements. But the challenge lies not in generating information, but intranslating that information into clear guidance for the public. Technical bulletins can be confusingfor ordinary people, rural communities may not have consistent internet access, andmisinformation often spreads faster than official announcements. As a result, many families onlyrealize the severity of a situation when the floodwater is already at their doorstep or when alandslide cuts off their route.Artificial Intelligence (AI) chatbots have emerged globally as a powerful tool for addressing thesecommunication gaps. In simple terms, a chatbot is an automated digital assistant that people cantalk to through familiar platforms such as WhatsApp, Facebook Messenger, Viber, SMS, or evenvoice systems. During emergencies, this chatbot becomes a 24/7 helping hand, ready to answerquestions instantly. A person can simply type: 芒鈧揑s my village at risk tonight?芒鈧� or 芒鈧揌ow much hasthe river risen?芒鈧� or 芒鈧揥here is the safe evacuation centre. and receive an immediate responsebased on official data, free from the delays that typically affect manual communication systems.A major strength of AI chatbots is their ability to provide information in Sinhala, Tamil, and English.Sri Lanka芒鈧劉s diverse language landscape often creates barriers during emergencies, especially whenwarnings are issued only in one language. A multilingual chatbot ensures that every citizenwhether in Colombo, Jaffna, Batticaloa, Galle, Matara, Badulla, or Ratnapura receives life-savinginformation in a language they fully understand. This feature is especially important for elderlypeople living alone, migrant workers unfamiliar with formal technical terms, and schoolchildrenwho may need clear instructions in simple language.

Beyond translation, chatbots simplify complex information into easy-to-read, friendly messages.Rather than receiving a technical warning like 芒鈧搑iver gauge exceeded critical threshold,芒鈧� a personreceives a human-like message: 芒鈧揟he River in your area is rising quickly. Move to safe groundnow.芒鈧� This clarity helps people act quickly and confidently. It reduces confusion, panic, andhesitation芒鈧€漟actors that often lead to tragic outcomes during fast-moving floods and landslides.MisinformationOne of the most dangerous elements during disasters is the spread of misinformation. Rumoursabout dam failures, evacuation orders, or road closures often circulate through WhatsApp andFacebook. In many cases, these false alerts cause unnecessary panic or distract emergencyservices. AI chatbots provide a solution by instantly verifying whether a forwarded message isreal or fake. If someone receives a frightening rumour, they can simply forward it to the chatbotand receive a clear response: 芒鈧揟his message is not from an official source. Please follow verifiedupdates only.芒鈧� This function helps maintain public calm and prevents communities from makingdecisions based on unreliable information.Another transformative capability of chatbots is their support for two-way communication.Traditional disaster alerts operate in one direction: from authorities to citizens. However, duringemergencies, people on the ground often have more immediate knowledge of conditions thancentral agencies. A chatbot allows citizens to send geo-tagged photos, voice notes, and writtenreports of rising water levels, blocked bridges, fallen trees, broken embankments, or landslidecracks. These real-time updates help authorities gain a clearer understanding of how a disaster isunfolding across multiple locations. Instead of relying solely on fixed sensors or delayed fieldreports, emergency teams can receive fresh information directly from affected communities,enabling faster decision-making and more targeted rescue operations.To integrate AI into Sri Lanka芒鈧劉s disaster communication ecosystem, the Sri Lanka AI-EnabledDisaster Communication Framework (SL-AIDCF) has been proposed. This framework organisesthe entire process into four interconnected layers. The first layer focuses on collecting hazard datafrom national sources, ensuring that the chatbot is always connected to verified, up-to-dateinformation. The second layer processes this data using AI this includes interpreting weatherpatterns, predicting potential risks, translating information, checking accuracy, and tailoringmessages for each user. The third layer distributes alerts and responses across multiplecommunication platforms, ensuring that even if one network fails, others remain functional. The

fourth layer enables citizens to interact with the system, ask questions, send reports, and receivespersonalised guidance.Four-layer approachThis four-layer approach ensures that disaster communication becomes more inclusive, reliable,and responsive. It also recognises that technology alone cannot save lives; it must work hand-in-hand with people. AI chatbots support human responders by reducing their workload, allowingthem to focus on urgent rescue operations rather than spending hours answering phone calls orchecking rumours. For rural communities, the chatbot becomes a trustworthy companion intimes of fear and uncertainty, offering both practical instructions and emotional reassurance.Equally important is the role of chatbots in empowering vulnerable groups. Many elderly citizensstruggle to read long text messages, particularly during stressful situations. The chatbot can usevoice features to deliver spoken instructions with clarity. People with disabilities can receivetailored instructions based on their needs, ensuring they are not left out during evacuations. Evenhouseholds with low digital literacy can interact with simple button-based menus instead oftyping long questions.AI chatbots can also contribute to long-term disaster preparedness. During quieter periods, thechatbot can send reminders about creating emergency kits, safe evacuation routes, familycommunication plans, and how to protect important documents. By educating the public year-round, the chatbot fosters a culture of readiness, reducing panic when disasters occur.In many communities, the introduction of such technology could transform the way people relateto disaster information. Imagine a farmer in Ampara receiving a chatbot alert about heavy rainfallexpected overnight and moving his livestock to higher ground, preventing major losses. Imaginea mother in Galle receiving a midnight warning and calmly guiding her children to a safe locationbecause the chatbot explained the situation clearly. Imagine a group of schoolchildren in Badullausing the chatbot to verify a circulating rumour and preventing fear from spreading in theirneighborhood. These everyday scenarios highlight the human impact of AI-enabledcommunication.Bridging the gap in informationSri Lanka stands at an important moment in its disaster-management journey. The country芒鈧劉sresilience depends not only on dams, weather radars, or emergency shelters, but also on theability to communicate timely, accurate information to its citizens. Traditional systems sirens, SMSblasts, media announcements are not enough in an age defined by rapid climate change anddigital misinformation. An AI-powered communication system bridges this gap by combiningspeed, intelligence, and compassion.

The adoption of AI chatbots does not replace human responders; instead, it enhances their abilityto protect lives. A firefighter, a district officer, or a Grama Niladhari can make better decisionswhen armed with real-time community reports and predictive AI insights. A family living near ariver can evacuate safely when given clear instructions hours before the water rises. A mothercaring for children can verify messages instantly, avoiding panic caused by false rumours.As Sri Lanka prepares for the increasing challenges of climate change, forward-thinkingcommunication tools like AI chatbots offer a pathway to greater national safety. They representnot just a technological upgrade, but a commitment to protecting every citizen no matter theirlanguage, income, or location. In a world where disasters can escalate in minutes, having a trusteddigital assistant in your pocket may be the most powerful tool of al
