Quantifying the effect of green-roof and urban green infrastructure ratio on urban heat island mitigation -semi-arid climate

Abstract

Green Roof (GR) is one of the most applied strategies to Mitigate Urban Heat Island (UHI) recommended for sustainable cities. This research aims to examine and evaluate the effect of the GR/UGI ratio on UHI mitigation, creating Urban Cool Island (UCI). The study was carried out at Constantine, situated in the East part of Algeria, characterized by a semi-arid climate with high summer solar radiation intensity. An urban climate analysis was conducted during the hottest period of the year by means of remote sensing data using ArcGIS 10.2 platform. The results displayed that vegetation, urban density, and topography strongly affect UHI. Furthermore, other finding results in this research show that fixing GR/UGI ratio (with 0.0063 reduced the average air temperature by 1.24°C) in a large-scale urban area, can reduce the surface temperature by 4.00 degrees of the studied area.

The Influence of Green Infrastructure and Community Participation on Sustainable Natural Resource Management in Indonesia

“…The results of the interviews align with existing literature, highlighting the importance of green infrastructure and community participation in promoting sustainable natural resource management [5], [6], [12], [24]. The insights provided by the participants underscored the need for holistic approaches that prioritize ecological integrity, social equity, and institutional capacity building to achieve lasting conservation outcomes.…”

Analysis of Climate Change Effect on Extreme Precipitation Event in Constantine Algeria

“…In Constantine, Algeria, there is a growing interest in extreme weather events (Boudiaf et al, 2020;Guerroudj, 2023). Recent research studies (Sahabi and Matzarakis, 2017; Sahnoune et al, 2021;Taïbi et al, 2022) have mainly focused on extreme air temperature events, showing a significant increase, especially during summers. Given the region's vulnerability to extreme heat, it is important to expand these studies to understand the dynamics of extreme precipitation, which could worsen current challenges and bring new ones.…”
