Rapid and unplanned urbanisation can lead to altered local climate by increasing land surface temperature (LST), particularly in summer months. This study investigates the Urban Heat Island (UHI) Greater Cairo, Egypt, using remote sensing techniques estimate LST of months over 45 years (1986, 2000, 2017, predicted year 2030). The research objectives steps were, 1- mapped use/ cover (LULC), 2- c...

An essential part of urban natural systems, urban green spaces play a crucial role in mitigating the urban heat island effect (UHI). The UHI effect refers to the phenomenon where the temperature within a city is higher than that of the surrounding rural areas. The effects of the spatial composition and configuration of urban green spaces on urban land surface temperature (LST) have recently bee...

From the ecological effect of urban green space system, this paper illustrates the necessity and importance of inter-disciplinary evaluation of the urban green space system from the ecological perspective and analyzes the mechanism of action of urban green space in relieving the heat island effect. The quantitative evaluation approach for the thermal environmental impact of urban green space sy...

Worldwide urbanization has significantly changed the landscape in recent decades, which resulted in an urban heat island (UHI) phenomenon. This study quantitatively analyzed the spatiotemporal changes of the urban heat island (UHI) of Zhangzhou estuary city of China, in the context of urbanisation using Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) thermal images acquire...

• Technical and practical inadequacy of the UHI concept critically reviewed. Proposed a novel system-based paradigm for re-conceptualized studies. Implications to urban planning policy making discussed. Past decades have seen drastically increasing research effort progress on study phenomenon heat island (UHI). Despite its simplicity, this convenient has promoted significant advances in scienti...

The rapid increase of impervious surfaces and the dense development that accompanies urban growth has reduced the amount of green space in urban landscapes and increased urban surface temperatures. Accordingly, the greening of urban spaces has been proposed as one approach to mitigating urban heat island (UHI) effects. To find the most practical green space design for reducing land surface temp...

EnergyPlus V9.0 simulations of a typical small office building prototype in five USA cities (Albuquerque, Atlanta, Buffalo, San Diego, Rochester) indicate that adding cool roof (albedo 0.6) for an aged grey 0.2) would reduce the annual energy and cost all hot dry or humid Diego) severe cold mixed (Buffalo, Rochester). The CO2, SO2, NOX savings are positive selected cities. This work considers e...

The population growth, changing consumption patterns, and rapid urbanization contribute significantly to the growing volumes of solid waste that are generated in urban settings. As the rate of urbanization increases, demand on the services of solid waste management increases. The rapid urban growth in Langkawi Island, Malaysia, combined with the increasing rates of solid waste production has pr...
