Abstract. This research aimed to assess the tsunami flow velocity and height reduction produced by a planned elevated road spanned parallel to the coast of Banda Aceh called Banda Aceh Outer Ring Road (BORR). Cornell Multi-Grid Coupled Tsunami Model (COMCOT) was used to simulate eight scenarios of the tsunami. One of them was based on the 2004 Indian Ocean tsunami. Two magnitudes of earthquake were used, that is, 8.5 and 9.15 Mw. Both the earthquakes were generated from the same source location as in the 2004 case, around the Andaman Sea. Land use data of the innermost layer of the simulation area were adopted based on the 2004 condition and the land use planning of the city for 2029. The results of this study reveal that the tsunami flow depths and flow velocities can be reduced by about 9 % by using the elevated road for earthquake magnitude 9.15 Mw and about 22 % for earthquake magnitude 8.5 Mw. Combined with the land use planning 2029, the elevated road could reduce the maximum flow velocities behind the road by about 72 %. Notably, the proposed land use for 2029 will not be sufficient to deliver any effects on the tsunami mitigation without the elevated road structures. We recommend the city to construct the elevated road as this could be part of the co-benefit structures for tsunami mitigation. The proposed BORR appears to deliver significant reduction of impacts in the smaller intensity tsunamis compared to the 2004 Indian Ocean tsunami.

Abstract. This research aimed to assess the tsunami flow velocity and height reduction produced by a planned elevated road parallel to the coast of Banda Aceh, called the Banda Aceh Outer Ring Road (BORR). The road will transect several lagoons, settlements, and bare land around the coast of Banda Aceh. Beside its main function to reduce traffic congestion in the city, the BORR is also proposed to reduce the impacts of future tsunamis. The Cornell Multi-grid Coupled Tsunami Model (COMCOT) was used to simulate eight scenarios of the tsunami. One of them was based on the 2004 Indian Ocean tsunami. Two magnitudes of earthquake were used, that is, 8.5 and 9.15 Mw. Both the earthquakes were generated from the same source location as in the 2004 case, around the Andaman Sea. Land use data of the innermost layer of the simulation area were adopted based on the 2004 condition and the land use planning of the city for 2029. The results of this study reveal that the tsunami inundation area can be reduced by about 9 % by using the elevated road for the earthquake of magnitude 9.15 Mw and about 22 % for the earthquake of magnitude 8.5 Mw. Combined with the land use planning 2029, the elevated road could reduce the maximum flow velocities behind the road by about 72 %. Notably, the proposed land use for 2029 will not be sufficient to deliver any effects on the tsunami mitigation without the elevated road structures. We recommend the city to construct the elevated road as this could be part of the co-benefit structures for tsunami mitigation. The proposed BORR appears to deliver a significant reduction of impacts of the smaller intensity tsunamis compared to the 2004 Indian Ocean tsunami.

Banda Aceh was the most affected city by the 2004 Indian Ocean Tsunami. This city has grown rapidly because of disaster recovery activities. Therefore, this study aims to identify the types of urban physical growth in Banda Aceh City quantitatively from 2005 to 2019. The characteristics of growth were identified by integrating geographic information systems and remote sensing. The analysis showed that the main types of urban physical growth in the city were edge-expansion in 2005-2009 and infilling in 2009-2019. The percentage of spontaneous growth area was the lowest in both periods. The process of reconstruction and rehabilitation was considered to greatly affect the types of urban physical growth, where newly built-up areas were established close to the existing built-up areas. This also caused urban densification in a relatively short time. The process of urbanization had reached a stable stage in the city so that the surrounding suburbs have the potential to experience regional transformation. Overall, the approach used in this study resulted in a more objective understanding of identifying the urban physical growth characteristics for better urban planning.

Urban sprawl is a global phenomenon in the contemporary era. It is mostly taking place in the less developed countries due to natural increase and consistent movement of people into the mega cities and large urban centers. The phenomenon has globally gained attention from diverse researchers in the field of urban geography, environmental studies, city and region planning in view of its significant influence on the urban environment. However, the effect of sprawl on urban livability and economy in Nigerian cities is scarcely investigated especially in Northern Nigeria. This research explores the social and economic effects of urban sprawl in Kaduna metropolis. Remote Sensing and Geographic Information System (GIS) Technologies were applied for the analysis. The study found that Kaduna metropolis has experienced a progressive increase in the built-up area; in 2006 it had an aerial coverage of 13,980 hectares, a rise of 107.91% from 2001 aerial coverage of 6724 hectares. In 2012, the city had an aerial coverage of 15,808 hectares, an increase of 13.08% from 2006. Conversely, there has been a remarkable decrease in percentage of vegetation (1,458 hectares) and agricultural (11,739 hectares) land areas. In turn, such changes has adversely affected urban facilities or utilities such as pipe-borne water, electricity, health facilities, schools, security, transportation, wastewater infrastructures and fire safety services, which has become overstressed. Economic crisis has manifested in the rise of unemployment and escalating number of urban poor. Residential land use has encroached into open spaces while commercial activities overrun residential areas. Increase in distance and journey time make travel cost unbearable to the common man. These and social fragmentation retard livability in the city. Thus calls for a balance sustainable development in Kaduna metropolis and effective management of urban growth by the Kaduna Capital Development Board Authority. In due course, smart growth policy, growth management, urban containment, effective land use planning and public facility adequacy have been recommended to foster viable urban growth in Kaduna city and elsewhere.

Barriers to the application of climate science in land use planning are often understood as a problem related to perceived disciplinary knowledge gaps. This paper argues that, instead, limitations to the application of knowledge are not strictly linked to transference, but are also attributed to the thought processes that planners use to understand and use information. This study uses an interactional co-production framework from Science and Technology Studies (STS) to explore these processes in the context of heat response planning in Chatham County, Georgia, in the United States: a coastal county exposed to hot and humid conditions that render its population, particularly its growing elderly and low-income, vulnerable to heat health risks. We specifically focus on the processes used by planners during a heat response planning workshop, exploring the discussions and actions taken to develop a plan. We attempt to answer the following questions: What are the processes used by planners to respond to climatic issues such as heat vulnerability? How do these processes determine the application of the scientific knowledge produced? How does this process enable or limit the use of climate knowledge in decision making at the city scale? This paper argues that planners engage in three steps to determine the applicability of climate knowledge to urban planning: (1) using their own experiences to contextualize and visualize the information in their community, (2) being extremely cautious about the use of information because of a fear of failure, and (3) asking for specific policies to be in place to justify and legitimate actions and promote projects throughout the city. Using these insights, this paper concludes with some thoughts on how climate knowledge might be better integrated into urban planning.

Kapuskasing, Ontario warrants special mention in the history of Canadian land use planning. The town first acquired special prominence immediately following World War I when it was the site of the first provincially-planned resource community in Canada. The early layout of the settlement reflected the imprints of both the "city beautiful" and "garden city" movements. After 1958, the resource community then became the focus for an important experiment in urban "fringe" rehabilitation at Brunetville, a suburban area situated just east of the planned Kapuskasing townsite. The author suggests that the role of the Brunetville experiment in helping to change the focus of urban renewal in Canada from redevelopment to rehabilitation has not been fully appreciated.
