Sustainable and resilient built infrastructure systems provide the basic needs of society and are essential for viability, health, and welfare. Civil, environmental, and ocean engineers play an important role in enhancing human life through infrastructure modernization, including the provision of settlements, clean water, sanitation, transportation, and other essential public services.

The rapid pace of urbanization and industrialization has intensified environmental challenges, including environmental mismanagement, which contributes to global issues such as climate change, soil erosion, sea-level rise, hurricanes, groundwater pollution, and depletion of natural resources. These conditions have reinforced the importance of sustainability to safeguard future generations. In addition, unexpected hazards such as pandemics, natural disasters, and human-induced disasters highlight the need for resilient infrastructure systems that can prepare for, respond to, and recover from disruptive events while minimizing social and economic impacts.

Sustainability and resilience have therefore become major concerns among researchers and professionals worldwide. Addressing these challenges requires multidisciplinary collaboration that encompasses not only physical infrastructure, but also institutional frameworks, regulations, governance, and public policy that support long-term infrastructure development.

In many developing countries, including Indonesia, infrastructure limitations continue to hinder investment and economic development. Beyond financial constraints, sustainable infrastructure development faces challenges related to knowledge transfer, human resource capacity, best practices, and institutional development. At the same time, developing countries possess valuable local resources, environmental carrying capacity, and indigenous knowledge that can support future infrastructure solutions. Learning from past experiences and understanding present conditions are essential to designing resilient infrastructure for the future.

Meeting these multifaceted challenges requires integrated planning, innovative design, effective implementation, comprehensive verification, and clear policy directions. Through an integrated, multidisciplinary, and holistic approach, the global movement toward sustainable and resilient infrastructure should translate into practical engineering applications that optimize technical performance while maximizing environmental sustainability, social benefits, and long-term resilience.
