The correct planning of green cities is becoming an increasingly urgent priority and a central objective of the European Green Deal. Yet, urban green projects—parks, gardens, green buildings, and green infrastructures—are still too often approached primarily from architectural, aesthetic, technological, or economic perspectives, with limited attention to their ecological foundations.

This volume advocates for a broader and more integrated vision, emphasizing the essential role of plants and natural processes in urban planning. Moving beyond purely agronomic considerations, it highlights the importance of ecological principles in shaping sustainable and resilient interventions at local and urban scales.

Addressed to university students, public administrators, planners, and technical professionals, the book is structured in three parts. The first introduces the fundamental concepts of urban botany; the second explores the evolving relationships between plants and people in a changing society; and the final section presents methodological approaches and practical case studies for effective urban green interventions.
