Green infrastructure, a thermal regulator for the arid city. Case study of the city of Bou-saada

From a sustainable development perspective, becoming aware of the preservation green spaces and creation infrastructure is great challenge for Algerian arid city, especially in environment. Green multifunctional open space networks aimed at resource management environmental improvement. We chose city Bou-saada as case study to demonstrate need infrastructure. This with semi-arid climate, presents very varied, complex fragile historical, archeological natural richness subjected strong anthropogenic pressures. The overall objective this research assess using qualitative barometer. method uses several themes around concept multifunctionality thermal comfort, also some subthemes break down themes. can withstand drought heat emanating from area, provide shade reduce heat, prevent soil degradation desertification by stabilizing mitigating wind-induced erosion. Through research, we have looked issues such safeguarding heritage, combating desertification, siltation.
