The modern sustainability project is built on the promise that evolving technologies can reconcile urban and economic growth with ecological responsibility. By the metrics developed by the built environment professions and the policies adopted by governments, progress is tangible and accelerating: buildings consume less energy per square foot than they did a generation ago, vehicles emit fewer pollutants per mile, and urban infrastructure is more integrated and measurably cleaner in many cities. And yet total resource consumption continues to rise. Sustainability, as currently practiced across the built environment professions, has become a strategy for optimizing consumption rather than reducing it. Until the profession is willing to question the scale and structure of demand rather than the efficiency with which that demand is met, its most celebrated achievements will continue to fall short of the problem they claim to address.

Shenzhen is China's first Special Economic Zone（SEZ), serving as a window for China's Reform and Opening-up and an emerging immigrant city. It has evolved into an influential, modern, and international metropolis, creating the world-renowned "Shenzhen Speed" and earning the reputation of the "City of Design." Architectural design stands as the most intuitive expression of Shenzhen's spirit of integration and innovation. Over the past decade (2015-2025), the development of urban architecture in Shenzhen has closely integrated with its open and inclusive urban character, ecological advantages of being nestled between mountains and the sea, and the local spirit of blending traditional culture with innovative technology, showcasing Shenzhen's unique charm and robust vitality across multiple dimensions.

Make Space for Girls (MSFG) is a London-based charity that campaigns for public spaces and parks in the United Kingdom to be more inclusive of teenage girls. The organization conducts research on how public spaces are used and designed, raises awareness about perceived inequalities in their use, and collaborates with public and private institutions to promote the representation of teenage girls in the planning and design of outdoor environments. Their research indicates that their exclusion from the design of parks and public spaces often leaves them without places where they feel welcomed or valued, and that parks and public spaces for older children and teenagers are currently designed for the default male. From 8 to 15 October, the organization is running a fundraising campaign to support the implementation of its new three-year strategy aimed at promoting more inclusive public spaces.

Contemporary cities are vibrant, complex, and constantly evolving. Above all, they are ever-changing, mutable, and diverse. What transformative changes are occurring, and where are they leading us? Urbanization continues to gain momentum in many regions of the world, generating visible and structural transformations. As this unfolds, data on the evolution of its configuration and the challenges we encounter begin to emerge. According to the World Bank, the urban population will continue to trend upward, with 90% of new urban residents concentrated in Africa and Asia. This growth raises essential questions: How can we consolidate a design approach that ensures equitable access to spaces, resources, and services? How can we make emerging and consolidated metropolises more inclusive and accessible?
