Prof. Muhammad Raisuddin Ahmed, Vice president of BoT of Canadian University of Bangladesh presented a keynote on IoT for Controlled Environments: Building Smart Plant Factory Infrastructures at 3rd International Conference on Big Data, IoT and Machine Learning (BIM 2025) on 25th September 2025 in Bangladesh Institute of Management, Dhaka, Bangladesh. This keynote, spotlighting case studies, research findings, and future development avenues, elucidates how IoT-enabled smart infrastructures stand to transform plant factories and offer a working model for sustainable urban agriculture and resilient food systems.

The new Agriculture paradigm is getting a paradigm shift under stress from booming urban population, climate change, and limited land for crops, so controlled environmental systems such as plant factory labs based on precision technology have been developed to ensure year-round production of crops with efficient use of resources, irrelevant of seasonal and geographical limitations. The IoT acts as a key enabler of this transformation through the integration of sensor networks, smart actuators, and cloud analytics over agricultural infrastructures to build resilient ecosystems, in which temperature, humidity, light intensity, carbon dioxide, and nutrient flows are monitored in real time, thus allowing precise intervention in crop growth conditions. Pairing those capabilities with advanced data analytics and AI-driven decision support, IoT ensures the best use of resources, highest yields, reduced operational costs, predictive maintenance, supply chain transparency, and methods that serve global food security and climate resilience goals. This keynote, spotlighting case studies, research findings, and future development avenues, elucidates how IoT-enabled smart infrastructures stand to transform plant factories and offer a working model for sustainable urban agriculture and resilient food systems.
