Planification paysagère et durable : vers une inté-gration écologique des activités humaines en milieu urbain.

Abstract

This research examines sustainable landscape planning as a framework for integrating human activities within urban environments. Through the case study of the city of Sétif, it investigates the potential of Nature-based Solutions (NbS) and the connectivity of Green and Blue Infras-tructure networks to address environmental challenges associated with contemporary urbaniza-tion, particularly land artificialization, the decline of vegetated spaces, and the intensification of Urban Heat Islands (UHI). A mixed-method approach was adopted, combining spatial dia-gnosis, a quantitative survey involving 107 citizens, and semi-structured interviews with local institutional stakeholders. The findings reveal a significant shortage of green spaces, reported by 64.2% of respondents, as well as substantial inequalities in their spatial distribution, highlighted by 78.3% of participants. To address these issues, two eco-landscape planning pro-posals were developed: the renaturation of the Oued Bousselam riverbanks as a resilient peri-urban ecological corridor and the environmental requalification of Sétif’s industrial zone through the integration of vegetative filtering buffers and permeable surfaces. Finally, the study proposes strategic guidelines for major urban sites in order to promote a more sustainable, equi-table, and climate-resilient development model
