Integrating climate adaptation measures into urban development has emerged as a holistic approach to minimize climate change impacts and to enhance urban resilience. Although there has been an initial implementation of the integrated strategy at the national level, the progress of its adoption at the local level is relatively less studied. The study aims to examine the integration development of climate adaptation measures into urban development strategies by looking at its drivers and benefits in two coastal cities of Indonesia, i.e., Semarang and Bandar Lampung. Both cities have experienced climate change impacts and the preliminary effort of the integration process. The study was depended on close-ended Likert-scale questions with key actors representing local authorities and relevant stakeholders. Then, a Weighted Average Index was applied to transform their perceptions. The assessment of their knowledge of related issues was conducted. Secondary data was obtained from a desk study. The study found out that the effort of the integration process had influenced stakeholder’s understanding of the issue of climate change and urban development, as well as its relationship. The level of stakeholder’s knowledge related to the issue was very high. The result also revealed that the most influencing driver of the integration process is related to the motivation and initiative of municipal officers. It significantly contributed local governments to adopt its integration strategy. There was a strong consensus regarding the benefits of the integration process. They believed that it could ensure sustainable urban development in the future. This empirical study distinguishes the significance of integration development based on the local perspective for the approach improvement. The results could be applied to encourage other local municipalities in other emerging coastal cities.
