- Environmental Benefit: Drones help reduce the need for manual intervention in dangerous environments, improving safety and efficiency.
- IoT Cameras: Smart cameras equipped with sensors can be placed in disaster-prone areas (e.g., near floodplains, volcanoes, or earthquake-prone regions) to monitor environmental changes such as shifts in land movement, abnormal weather patterns, or early signs of disaster.
- Impact: Continuous monitoring and early detection of potential risks.
- Environmental Benefit: Helps in providing more accurate predictions, reducing human intervention, and limiting disaster damage.
2.3. Search and Rescue Operations
IoT-enabled wearables and tracking systems play a vital role in search and rescue missions during a disaster.
- Smart Wearables for Rescue Teams: Rescue personnel can wear IoT-enabled devices like smart helmets or body-worn sensors that track their location, vital signs (heart rate, body temperature, etc.), and environmental conditions. These devices allow control centers to monitor the safety of rescue teams in real time.
- Impact: Improves safety of rescue workers and enables fast, informed decisions.
- Environmental Benefit: Reduces the number of casualties among rescue teams and minimizes environmental risks to human health.
- Tracking Devices for Victims: IoT-enabled wearable devices or RFID tags can be attached to victims in disaster zones, enabling rescue teams to track their exact locations and condition. These devices can send distress signals, providing valuable information about the person’s health and safety status.
- Impact: Enables faster identification and rescue of disaster victims.
- Environmental Benefit: Reduces the time required for search operations, leading to faster recovery and minimizing the environmental impact of prolonged rescue efforts.
2.4. Smart Shelters and Temporary Housing
During a disaster, providing shelter for displaced individuals is a priority. IoT technology can help improve the management of temporary housing or smart shelters.
- Temperature and Humidity Control: IoT-enabled climate control systems in shelters can help ensure comfortable living conditions for survivors by adjusting the temperature, humidity, and air quality in real-time.
- Impact: Improves the living conditions of disaster survivors.
- Environmental Benefit: More efficient use of energy in temporary shelters, reducing waste and resource consumption.
- Smart Water and Waste Management: IoT sensors can monitor water usage, waste levels, and air quality in temporary housing units, ensuring efficient resource management and cleanliness.
- Impact: Better health and sanitation for survivors.
- Environmental Benefit: Reduced waste, improved hygiene, and more sustainable resource management.
2.5. Resource Management and Logistics
During a disaster, efficient resource management is essential for saving lives and preventing chaos. IoT helps optimize logistics and distribution of critical resources like food, water, medical supplies, and emergency services.
- Asset Tracking: IoT systems that track resources (e.g., medical supplies, food, equipment) ensure that they are deployed to the right locations in a timely manner. GPS-enabled tracking devices help track the movement of relief vehicles, supplies, and equipment.
- Impact: Ensures timely and efficient distribution of resources.
