The water sector is one of the most important sectors to be influenced by climate change impacts, in the form of water shortage. Currently, for an example, the Java- Bali regions have already faced a deficit in its water balance. Based on climate projections, most regions in Indonesia will suffer from a gradual decrease of water supply due to temperature increase and rainfall changes that will affect the water balance. Combined with estimated population growth rates, increased water demand will cause severe water shortages to occur, especially in Java and Sumatra for the period of 2020-2030. This paper identifies several high risk regions throughout Indonesia based on the national level of climate risk study. It is found that areas which possess high risk on water shortage stretch in some parts of the Java-Bali region, especially in a few locations in the northern and southern of West Java, middle and southern of Central Java and East Java; as well as in the capital of the North Sumatra, West Sumatra, Bengkulu and Lampung (Sumatra), Nusa Tenggara Barat and South Sulawesi. This paper concludes with some possible actions to adapt to the impacts of climate change to water shortage.

Abstract

Spatial planning is expected to facilitate climate change adaptation by directing future spatial and infrastructure developments away from zones that are exposed to climate-related hazards. This study attempts to confirm this understanding by mapping the effects of the various spatial plans on the northern coast of Java, Indonesia. First, the study maps the extent of coastal hazards for the baseline year of 2010 using a GIS-based inundation model. An overlay in GIS demonstrates the influence of spatial plans for the projection year of 2030. This allows for calculating the economic losses of the planned developments. The case study shows that the current provincial spatial plans direct land use conversions along the northern coast of Java to continue to occur in the future. This could significantly decrease the regional capacity in dealing with the exposure to coastal inundation. The analysis also demonstrates that a total area of 55,220 ha of land prone to inundation, consisting of protected area (1488 ha), fishponds (32,916 ha) and agricultural land (20,814 ha), is planned to be converted into industry (13,399 ha) and settlements (41,821 ha). Thus, these areas will be also prone to inundation in 2030. This change would potentially lead to an economic loss of 246.6 billion USD. The spatial plans issued by the national and provincial governments for regulating the future land use on the northern coast of Java have not integrated measures against hazards related to global sea level rise. Meanwhile, many existing developments have already been affected by coastal inundation. Rather than reducing the exposure towards coastal flood hazards, the case study shows that spatial plans could even increase the risk of climate-related hazards and cause higher economic losses. These findings provide a different perspective on the role of spatial planning for climate change adaptation than what is stated in the literature.

Purpose – This paper aims to explore the extent to which risk communication has been implemented into spatial planning practice in Indonesia by using the coastal area of Subang Regency as a case study. Risk communication in risk-based planning (RBP) is the process of exchanging information about risk and hazards between all actors which emphasizes determining the level of risk acceptance of communities to support appropriate decision making in spatial planning. It has been proven effective in developed countries, but it remains unclear in Indonesia.
Design/methodology/approach – The study uses qualitative methods by analyzing documents and interviews with local stakeholders to explain how risk communication is implemented in RBP at the regency level.
Findings – This study reveals that risk communication is not explicitly incorporated into RBP regulations and impacts its practices. The absence of a clear definition and guidelines in regulations is leading to limited understanding at all government levels. The emphasis on community risk acceptance levels as the core of risk communication in RBP has not been conducted, where the existing focus is still majorly on disaster events. This has led to improper spatial planning decisions.
Practical implications – Incorporating risk communication in RBP is important in spatial planning practice in Indonesia. Without effective community engagement, clear definition and guidelines on community’s acceptable risk levels, spatial planning efforts may not align with local needs, leading to social conflicts and hindering appropriate spatial planning. For instance, land use policy for community that is willing to tolerate the risk should be permitted with specified consideration instead of offering relocation options that potentially lead to social unrest by conflicting with their social, economic and cultural. Integrating risk communication into RBP can result in a more adaptive and appropriate spatial planning decisions.
Originality/value – This study offers a novel exploration of risk communication which is important to be integrated into the RBP in a locality in Indonesia, focusing on both regulatory factors and practices to support appropriate decision making in spatial planning. This paper is important because study on risk communication in RBP in Indonesia is still scarce.

The purpose of this study was to determine how well KN95 respirators, marketed for children, fit the faces of children aged 6–13 years old in two urban sites with elevated levels of air pollution: Kathmandu, Nepal and Bandung, Indonesia. The wearability of the tested respirators and the children’s style preferences were also assessed. Sixty children, 30 in each country, were recruited and were fit tested with three different ear loop respirators in two combinations (with and without an additional adjustable ear loop clip worn around the head). The fit factor for each respirator was determined using a modified fit test protocol for filtering face piece respirators using a TSI PortaCount™ Respirator Fit Tester 8048. Facial dimensions were measured using callipers. The wearability of the respirators and children’s style preferences were assessed through questionnaires administered after the fit tests. Most fit factors were less than 10, i.e. less than 90 % reduction in exposure. In both countries, using an additional ear loop clip was associated with increases in fit factor of 42 and 50 % for Indonesian and Nepalese respirators, respectively. There were no significant differences among the respirators for any of the perceptions: comfort, feeling hot, breathability, fit, embarrassment or appearance for either country. The appearance of the respirator was important to the children. Although the use of an additional ear loop clip improved the fit, the respirators were generally too large for the children’s faces to achieve a good fit. Respirators marketed for children should be better designed to suit their facial dimensions

The dimensions of the triple bottom-line approach to sustainable devel opment contain inherent con icting goals in implementation. In cases of urban development around the world, this is exemplary for settings in major port cities. Here, mostly economically oriented infrastructure requirements of the ports meet more comprehensive concerns of sustainable urban development. There are inco herent governance systems: Ports are often involved in higher-level national plan ning hierarchies, while urban development is predominantly locally controlled. This is also the case in Jakarta Megapolitan with Tanjung Priok Port, Indonesia, the most prominent and still expanding national seaport. The port expansion is also aimed to be a signi cant hub in one of the world’s maritime axes, which refers to vast urban growth. However, the entire urban economic effects are uncertain, for example, con cerning urban diseconomies of scale or rebound effects, such as traf c congestion,
