“…Serrao-Neumann et al [50] discussed the importance of connecting land use and water planning. Ogie et al's [51] study emphasised on flood mitigation infrastructure, whereby it is crucial to remove accumulating floodwater from low-lying areas where drainage is naturally poor due to a very low slope gradient. A study by Zhang et al [52] concluded that the operating efficiency, operating performance, and service quality of a drainage enterprise is determined by its sustainable development level that involves urban wastewater treatment, construction of drainage engineering, operation and maintenance, and consulting.…”

By 2050, the population living in major cities, especially in developing countries, will have increased twofold. With the increasing majority of the population occurring in urban areas, it is crucial to focus on how technological innovation can help to deliver a sustainable future. A sustainable city strives to create a sustainable living environment through the use of technology. Thus, the main objective of this paper is to review the impact of technological innovation on building a more sustainable city. Technological innovation has changed the overall effectiveness and benevolence over time and with regard to sustainability. A sustainable city involves development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development encompasses all aspects of environmental stewardship, social development, and economic progress.

“…The city of Jakarta was selected for this study because it is typical of coastal mega-cities of developing nations, which are in urgent need of innovative solutions to the problem of flood disasters [16]. Jakarta has a rapidly growing population of over 14 million people, most of whom suffer from the annual monsoonal floods that typically occur between the months of November and March [17]. The impacts of the frequent and high-intensity flooding events experienced in Jakarta are aggravated by a number of factors, including physical geography, climate change, poor maintenance of drainage network, land subsidence, sea-level rise, shortage of funding, aging and deteriorating flood control infrastructure, unplanned and rapid urban growth, slum dwellings and illegal disposal of solid waste in waterways [17].…”

Georeferenced social media data are gaining increased application in creating near real-time flood maps needed to improve situational awareness in data-starved regions. However, there is growing concern that the georeferenced locations of flood-related social media contents do not always correspond to the actual locations of the flooding event. But to what extent is this true? Without this knowledge, it is difficult to ascertain the accuracy of flood maps created using georeferenced social media contents. This study aims to improve understanding of the extent to which georeferenced locations of social media flood reports deviate from the actual locations of floods. The study analyses flood-related tweets acquired as part of the PetaJakarta.org project implemented in the coastal mega-city of Jakarta and provides insight into the level of accuracy expected with using georeferenced social media data for flood mapping. Importantly, the results reveal that the accuracy of flood maps generated with georeferenced social media data reduces with increase in the size of the minimum mapping unit of the flood map. Finally, an approach is recommended for creating more accurate real time flood maps from crowdsourced social media data.Abstract-Georeferenced social media data are gaining increased application in creating near real-time flood maps needed to improve situational awareness in data-starved regions.

“…Socioeconomic factors constitute an important element of SPECTRUM. In the context of Jakarta, a densely populated city with many underprivileged citizens seeking to improve their economic well-being [119], one would think that low-priced monetary incentive will be effective in motivating people to engage in the crowdsensing process. However, given the terrain in which citizens are expected to collect data, i.e., flood conditions, there is a tendency that the use of monetary incentives will strongly influence the urban poor struggling to acquire enough earnings for daily survival to engage dangerously with flood hazards, potentially creating ethical and legal risks for the service provider.…”

“…In the context of Jakarta, privacy concerns exist, particularly for the urban poor living in informal settlements or slums situated along the watersides [119]. These people may be reluctant to contribute geo-located tweets because of fear that they will be traced by the government and punished for living in illegal settlements.…”

“…Furthermore, money as an element of SPECTRUM is a key factor that determines if monetary incentive is appropriate for a crowdsensing initiative or not. In Jakarta, the shortage of funding and the meagre budget available for disaster management demands that low cost approaches such as social incentives be adopted for incentivising data contributors to the PetaJakarta project [119]. In a nut shell, by consideration the various elements in SPECTRUM in relation to the unique context of the PetaJakarta system, one can infer that social incentives are most appropriate for motivating citizens of Jakarta to participant in the crowdsensing process.…”

Mobile crowdsensing is a burgeoning concept that allows smart cities to leverage the sensing power and ubiquitous nature of mobile devices in order to capture and map phenomena of common interest. At the core of any successful mobile crowdsensing application is active user participation, without which the system is of no value in sensing the phenomenon of interest. A major challenge militating against widespread use and adoption of mobile crowdsensing applications is the issue of how to identify the most appropriate incentive mechanism for adequately and efficiently motivating participants. This paper reviews literature on incentive mechanisms for mobile crowdsensing and proposes the concept of SPECTRUM as a guide for inferring the most appropriate type of incentive suited to any given crowdsensing task. Furthermore, the paper highlights research challenges and areas where additional studies related to the different factors outlined in the concept of SPECTRUM are needed to improve citizen participation in mobile crowdsensing. It is envisaged that the broad range of factors covered in SPECTRUM will enable smart cities to efficiently engage citizens in large-scale crowdsensing initiatives. More importantly, the paper is expected to trigger empirical investigations into how various factors as outlined in SPECTRUM can influence the type of incentive mechanism that is considered most appropriate for any given mobile crowdsensing initiative.
