The concept of “water smart city” is increasingly being recognized as a new approach to managing urban environments (including urban floods), especially in the context of developing countries, such as Indonesia. While Indonesia’s national capital relocation plan is expected to attract significant human migration to two nearby cities, Samarinda City and the port city of Balikpapan, these cities have continuously faced with severe risk of flooding. Therefore, this research proposes a flood management approach by reviewing the local city government’s flood risk management strategies and the smart city plan to enhance flood resilience. The integration of the SETS (Social–Ecological–Technological systems) framework and the Flood Resilience Cycle is undertaken to determine the state of flood management, which is followed by a review of smart city plans and programs in two selected cities (Samarinda and Balikpapan). The research mainly identifies how it can be implemented in the two selected cities based on SETS–FRC distribution. In accordance with the SETS–FRC (Flood Resilience Cycle) framework, it is revealed that both these cities have a higher emphasis on the flood prevention phase, as compared to other resilience phases. Based on the overall results, this study emphasizes the implementation of a water smart city concept for effective and smart flood risk management.

COVID-19 and climate change are widely recognized to negatively impact communities in developing countries. Like several other developing countries, Indonesia also dealt with climatic hazards such as flooding and landslides during the COVID-19 pandemic. Furthermore, after the Paris Agreement was signed, the government launched a “Climate Village” program or Kampung Iklim (ProKlim) to enhance community contribution in addressing climatic hazard impacts. Yet, numerous studies have researched integrating COVID-19 and climate change impacts, which calls for a concept of community resilience. To bridge this gap, the objective of this research is to understand and measure the local adaptation and mitigation activities in ProKlim through the smart village concept. Methodological literature review, situation analysis through interviews, and field observations are applied in this study. This research used five indicators to measure the current situation of the Climate Village, which are: resilience, mobility, community, perspectives and digitalization. The findings reveal that the implementation of smart villages in ProKlim is still in its preliminary stages and must seek innovation and system integration from smart cities and smart communities. This research also suggests feasible strategies to build community resilience: (i) collaborative governance in the Climate Village program implementation, (ii) promoting the Climate Village program to other sectors for ICT, and (iii) strengthening community participation in implementing the smart village concept.

The purpose of this paper is to examine the inter- and intra-relationships between climate change and urban flood risk in Balikpapan city. This study adopts a qualitative method by applying the driver–pressure–state–impact–response (DPSIR) framework, which helps to determine the strategies for reducing flood vulnerability in response to drivers, pressures, states and impacts. A secondary survey was conducted to understand the DPSIR. The key drivers are identified as the population growth, land-use change, climate change and urbanization. Secondary data show that population growth due to urbanization in Balikpapan city is very high, which means that there is a lot of demand for land in the city, and the city’s current responses are mostly focused on building flood control and prevention infrastructures like detention ponds, zero Q technology policies and green open space. The study reveals that the responses that have been implemented in Balikpapan are mostly ineffective problem-solving, which cannot reduce vulnerability to flooding for the long term. To the author’s knowledge, this is the first instance of the DPSIR framework being applied to Balikpapan city. It is, therefore, hoped that the study results will provide feasible directions to the city government for managing the future flood risks

As tourism and its related sectors have flourished in Bali Province, Denpasar Municipality, as the capital, has attracted significant urbanization. As a result of this development tendency, the city has become the densest location in the Bali Area. Denpasar Municipality is suffering with urban issues such as waste, land-use changing, housing bubble, and cultural asset loss as a result of the negative effects of urbanization. Not only from the degradation of urban livelihood threat, but Denpasar is also at risk from multi-hazard disasters such as earthquakes, tsunami, floods, extreme weather, forest and land fire, extreme waves, and beach erosion. Currently, the outbreak of the COVID-19 pandemic, as well as the decline of the tourism business, have forced Denpasar Municipality's resilience to the edge.In addition, to address the threat of disaster and urban issues in Denpasar, this research was conducted to analyze the resilience in the city. Yet, the previous studies have not been addressed the resilience of the urban crisis and disaster in a holistic approach. First, the semi-qualitative research by CDRI (Climate Disaster Resilience Index) Framework was conducted to measure the urban resilience in Denpasar. The result of five parameters (physical, social, institutional, economic, and environment) reveals that West Denpasar has the highest resilience score, followed by South, North, and East Denpasar. In addition, to assess the supporting and restricting resilience factors in Denpasar, a qualitative approach using semi-structured interviews with different responsible institutions for disaster management in Denpasar was undertaken. The result shows that sufficient infrastructure and facilities, bonus demographic, collaboration with the private sector, sufficient information access, and control from the government are the supporting factors of resilience while urbanization challenge, budget shifting, the management of the problem, the ownership of the asset, collaboration with the community and focus on physical loss and damage are the restraining factors of resilience in Denpasar Municipality.

The repercussions of the ongoing COVID-19 pandemic have expanded far beyond public health crisis, affecting the solid waste management system. The countermeasures to curb virus transmission have caused a major shift in waste generation pattern and composition. As a response, governments and international entities around the world – including Indonesia – establish a set of guidelines on solid waste that ensure safety for all while upholding the principle of a circular economy of waste through reducing, reusing, and recycling. This study aims to understand stakeholders’ involvement in household solid waste management (HSWM) in Pontianak City during the COVID-19 pandemic. A social network analysis was employed to pinpoint the stakeholders, their roles, characteristics, knowledge, and interactions in a case study area of Pontianak, Indonesia. The findings reveal that social network analysis conducted in this study highlights the interaction dynamic among the stakeholders. The Environmental Agency of Pontianak municipality is the central stakeholder in all centrality measurements. Meanwhile, the informal private sectors were constantly identified as the least central stakeholders within the household solid waste management network. Furthermore, the findings highlighted that stakeholder tend to interact with others within the same stakeholder group, representing the dysconnectivity of the network.

Citizen science is increasingly significant in scientific research and disaster management, especially as disaster risks intensify globally. While numerous studies confirm the value of citizen science programs in mitigating disaster risks, further research is needed to understand how these programs contribute to disaster risk reduction and to identify indicators of their success. This study investigates key success factors and challenges of citizen science programs through a case study of Safecast, a radiation monitoring initiative in Japan. Six critical factors were identified: active participation, knowledge production, data accuracy, expansion of spatial and temporal data, and citizen-related outcomes. Safecast’s broad engagement of participants, open-source data collection, and significant contributions to scientific research and policy decisions have been key to its effectiveness. In addition, the rigorous data accuracy measures and data expansion over time and space have further supported disaster risk reduction efforts. However, challenges remain in maintaining participant engagement, addressing the digital divide, and ensuring data consistency. Safecast exemplifies how citizen science can bridge grassroots data collection with formal disaster management, highlighting its potential to strengthen disaster resilience and empower communities.
