Urban water security is a multi-faceted water, socioeconomic, and governance challenge. The complexity of translating the holistic approach into policies is an important need for improving water resource management to achieve prosperity, equity, sustainability, and good governance. The city of Lamphun is an example of the practice, which faced drought and major challenges in efficiently distributing water to industrial partners and downstream residents. The purpose of this study was to monitor urban water security and formulate a water management-based urban land use policy for Lamphun Municipality to mitigate water conflicts and ensure access to water for all residents. Therefore, the study examined urban water security using 4 indices: urban water resources, access, risks, and governance. A careful urban land use plan responsible for water security was proposed based on potential surface analysis techniques and public participation. The result of this research would not only guarantee water security, but also promote public participation and sustainable communities.

Urban Sprawl, categorized by the city's outward expansion into their adjacent areas, has emerged as a pressing and complex challenge in urban development worldwide. Understanding the urban sprawl drivers becomes essential for efficient and sustainable urban development as cities transform and grow. Only some studies have provided a comprehensive analysis combining local perspectives with international understanding, making it challenging to form policies to prevent urban sprawl. This study is conducted with the primary aim of determining the drivers of urban sprawl. The qualitative analysis of focus group, interviews and document analysis have been done to reveal the multifaceted drivers of urban sprawl. The thematic analysis reveals the main role of economic incentives, government policies, accessibility, zoning regulation, cultural aspects, land use changes, Low Spatial Distribution of Productivity and limited Capacity of Dammam Urban Planning Department in influencing the spatial dynamics of urban sprawl in Dammam, Saudi Arabia. This research study connects the local context to the worldwide urbanization trends, contributing to the broader international perspective on the drivers of urban sprawl. The study findings will be helpful in effectively addressing the urban sprawl challenge. With the local focus and international insight, this research study offers a great knowledge for communities, policy makers and urban planners, enabling more sustainable urban development in Saudi Arabia and beyond.

A significant proportion of the world's population is currently experiencing heat stress. This results from the effects of global warming, urban heat islands (UHIs), and the growth of urban populations. Researchers have investigated multiple strategies to address this problem. It has been found that the outdoor thermal environment (OTE) can be modified by means of vegetation, water surfaces, and urban geometry. Several studies have indicated that certain geometric factors have demonstrated a higher degree of effectiveness in cooling the surrounding environment. OTE studies often employ two commonly utilised factors, known as urban geometry indicating parameters (UGPs)—the sky view factor (SVF) and height-to-width ratio (H/W). This article compares OTE studies focusing on these two factors. The comparison encompasses characteristics such as study methods, places and times of conducting, and thermal indices. The findings indicate that geometric studies have primarily relied on simulation and field measurement methods. These studies were predominantly conducted in tropical or subtropical cities during warm seasons, with a preference for daytime investigations. Complex thermal indices, including the physiologically equivalent temperature and mean radiant temperature, were commonly employed. In addition to UGPs, other physical factors, such as orientation, were also taken into consideration. Studies on H/W and SVF differed slightly although they are both geometrically indicative. This review can provide guidance for future studies in the field of urban geometry, in that researchers may choose to prioritise the examination of practical indicators, such as the energy load, to conduct a more comprehensive analysis while also taking into account other physical aspects, such as the presence of trees.
