Asia has undergone tremendous urbanization and infrastructure growth in the past decade, with almost half of the population now residing in urban areas. More than half of the world’s megacities are in Asia and the Pacific, and they constitute hubs of knowledge, culture, commerce, and industry. Parallel to the rapid growth of Asian economies, intense infrastructure investments are necessary to cater to the needs of the growing urban populations. Building quality and resilient infrastructure in developing Asia will require financial investments of approximately $1.7 trillion annually until 2030 to withstand the shocks of climate change (ADB 2017). Especially in the Pacific island countries (PICs) where regional interconnectivity and integration remains a challenge with rapid urbanization, providing sustainable infrastructure is key to ensuring the livelihood, economy, and climate adaptation of the region and necessary to achieve the Sustainable Development Goals.
