The Himalayan landscape, while breathtakingly beautiful, is marked by geographical isolation, climate sensitivity, and frequent natural hazards. This session focuses on sensor-based technologies and smart systems as critical enablers for real-time environmental monitoring, disaster risk reduction, and sustainable infrastructure development in the region. Drawing from advances in embedded systems, IoT, and remote sensing, this session will showcase how context-sensitive sensor networks can help bridge data gaps and empower early action in fragile mountain settings.
