Many historical areas are exposed to many problems and ongoing changes that may negatively affect those areas. One of these historical areas is Historic Jeddah in Saudi Arabia, which was placed on the UNESCO World Heritage List in 2014. This site is located within the scope of the second largest city in the Kingdom, which is witnessing a continuous urban movement in which the image of the city is changing in response to (Kingdom’s Vision 2030) to modernize the image of its major cities. The study aims to review the urban preservation strategies for historic Jeddah and the vision set for it through the ongoing modernization process of the city, especially with the projects that have been undertaken in it since 2021. The study follows both theoretical and descriptive approaches with the aim of reviewing current conservation strategies. This is with the aim of reaching results related to the challenges facing the area, demonstrating the effectiveness of the conservation strategies used, and deducing what could contribute in the future to the process of developing, preserving, and optimally exploiting it, without losing its value as a result of the modernization processes taking place now, but rather as a compatible part of it.

Given the context of global climate change, a worldwide increase in land surface temperature (LST) is anticipated, leading to the exacerbation and broadening of its impacts. This could jeopardize the environmental conditions in countries with a predominantly hot and harsh climate, such as Bahrain, one of the Cooperation Countries (GCC) nations. Conversely, Bahrain is currently experiencing significant population growth, leading to a surge in demand for land to accommodate the construction of additional residential developments. This circumstance allows investigation of the potential impact of land use and land cover alterations on the variation in Land Surface Temperature (LST). In order to accomplish this objective, a residential development project was executed within the timeframe spanning from 2013 to 2023. Four sets of Landsat 8 OLI/TIRS remote sensing datasets were selected, with each set corresponding to one of the four climate seasons. Each set consisted of two images: one capturing the study area before the commencement of the development process and the other depicting the study area after the completion of the development. The study area was analyzed by extracting the land surface temperature (LST), normalized difference vegetation index (NDVI), and normalized difference built-up index (NDBI) on various dates. Subsequently, correlation and regression analysis were employed to examine the interrelationships among these three variables. The findings demonstrated a notable rise in the mean land surface temperature throughout the spring and autumn seasons following the conclusion of land development activities. The findings indicate a positive and robust association between LST and NDBI across all seasons. Moreover, this relationship strengthened following the completion of development activities in the area. Conversely, there was a negative correlation between LST and NDVI prior to the region's development, which transformed into a positive relationship post-development. These results provide empirical support for the notion that small-scale residential developments contribute to a notable increase in LST, primarily driven by the expansion of impervious surfaces in built-up areas. The findings can potentially contribute to the formulation of localized adaptation strategies for small-scale residential development projects.
