Introduction
Climate change has emerged as one of the most critical challenges of the 21st century, significantly impacting urban structures and functions. Cities face increasing threats such as rising temperatures, sudden floods, droughts, and intense humidity, which affect not only urban infrastructure but also public health and quality of life. Cities like Rasht, located in northern Iran, are highly vulnerable to such hazards due to their ecological and climatic conditions. In this context, integrating climate resilience into urban design has become a strategic imperative for future-proof and sustainable cities.
Methodology
This research adopts a qualitative methodology, combining case study analysis, field surveys, content analysis of scientific literature, and conceptual design techniques. The Zarjub River was selected due to its significant ecological role and its potential for integrating climate-responsive spatial interventions. The design process involved site analysis, identification of vulnerabilities, and the generation of creative design solutions aligned with resilience goals. The study draws on four core concepts: climate resilience, sustainable urban design, climate-responsive design, and conceptual design thinking. Climate resilience refers to the capacity of urban systems to absorb, adapt, and transform in response to climate-related hazards. Conceptual design facilitates abstract thinking and innovative problem-solving in complex urban contexts, allowing designers to explore flexible and site-sensitive interventions. Climate-responsive design incorporates passive strategies, such as green infrastructure, water-sensitive design, and native vegetation to mitigate climate risks.
Results and discussion
Findings indicate that conceptual design, when aligned with climate-responsive strategies, significantly contributes to improving urban adaptability, reducing vulnerability, and enhancing citizen well-being. The flexibility of conceptual design allows for the development of visionary yet feasible spatial interventions that respond to both ecological and social dynamics. The project also demonstrates the importance of integrating community engagement and localized knowledge into the design process. The proposed intervention—“Health Pathway and Green Wellness Bridge”—is composed of five spatial sequences with diverse functions including recreation, mobility, ecological enhancement, and public amenities. The design integrates ecological continuity and social inclusiveness, improving physical connectivity and environmental quality along the river corridor.
Key design features include shaded pedestrian walkways, separate bicycle paths, ecological rest areas, multifunctional urban furniture, use of native plant species, and stormwater management systems. The Green Wellness Bridge not only physically connects the fragmented riverbanks but also symbolizes resilience and unity through its dual-level structure, incorporating a rooftop garden and interactive urban elements.
Conclusion
The findings of this research clearly demonstrate that conceptual design and the application of climate resilience principles play a pivotal role in minimizing environmental vulnerabilities and enhancing the quality and durability of urban infrastructure. Through the development of a localized and adaptable framework, this study presents a practical approach that can serve as a model for cities like Rasht, which face increasing climatic challenges such as flooding, heat stress, and ecological degradation.
It is recommended that urban planners and decision-makers in Rasht and similar urban environments adopt this framework as part of a proactive strategy to confront the multifaceted impacts of climate change. The integration of climate resilience into the core of urban design not only protects critical infrastructure but also supports long-term sustainability goals by improving environmental performance, community well-being, and resource efficiency.Moreover, the study emphasizes that achieving true resilience requires a comprehensive and interdisciplinary methodology—one that simultaneously considers social equity, economic viability, and ecological health. Addressing these dimensions together allows for more inclusive and adaptive urban policies and design solutions.By identifying the specific vulnerabilities and climate-related threats facing Rasht, and by proposing applicable and scalable design interventions, this research contributes meaningfully to the growing body of knowledge on sustainable urban development. It advocates for a shift from reactive to anticipatory planning, encouraging urban systems to evolve in harmony with environmental realities while enhancing the livability and adaptability of cities in the face of climate uncertainty.
