This ESCAP report analyses how artificial intelligence and digital technologies can promote the digitalization of small ports in the Asia-Pacific region to improve efficiency, resilience, and sustainability. It emphasizes that ports are critical infrastructure for global trade but many small ports face constraints such as limited resources, outdated systems, lack of interoperability, and vulnerability to climate risks. The report reviews global trends in AI-based technologies, including IoT, automation, blockchain, and digital twins, showing how they enhance operational performance and safety. It proposes a phased digitalization roadmap based on the ESCAP Port Level Maturity Model, highlighting the need to establish foundational systems such as e-documents, Maritime Single Windows, and Port Community Systems before adopting advanced solutions. It concludes with policy recommendations focused on capacity-building, international cooperation, and financing mechanisms to support sustainable and inclusive development of small ports
