Abstract
This study examines the applicability of xeriscape-based approaches in enhancing Istanbul’s climate resilience under the increasing pressures of global climate change—rising temperatures, irregular precipitation, and declining freshwater resources. Rapid urbanization, unequal green space distribution, and the intensifying Urban Heat Island (UHI) effect have weakened the city’s ecological stability. Drawing upon a multidisciplinary literature base that synthesizes principles of sustainable landscape architecture, urban ecology, and integrated water management, the research evaluates xeriscape strategies as adaptive frameworks rather than merely aesthetic interventions. Findings indicate that xeriscape-oriented models integrating sustainable water systems, native and drought-tolerant plant diversity, and spatial connectivity can effectively mitigate climate-induced stresses. Within this framework, a holistic planning model is proposed encompassing adaptive planting schemes, decentralized water infrastructure, multi-level governance, and participatory community engagement. Ultimately, the study not only presents a practical roadmap for strengthening Istanbul’s ecological resilience but also provides policy-relevant insights for urban planning institutions seeking scalable, evidence-based strategies for climate-sensitive urban management.
