Call Text:
The need to reconsider the relationship between nature and architecture has become increasingly urgent in today’s context. The climate crisis, the loss of biodiversity, and the depletion of natural resources demand new ways of inhabiting and designing. According to projections from the United Nations Human Settlements Programme (UN-HABITAT), by 2050 two-thirds of the world’s population will live in cities. At the same time, the Intergovernmental Panel on Climate Change (IPCC) warns that without substantial changes to current emission policies, global warming will surpass the critical threshold of 1.5°C.
In response, we must redefine the models of our cities to make them not only more livable, but fundamentally more efficient from the environmental and biodiversity preservation point of view. In this context, vegetation plays an essential role. One of the key challenges in architectural and urban thinking today is rethinking the presence of vegetation in urban environments and how it might transform our way of life.
In contrast to the modernist paradigm, often based on the separation and domination of nature, we are witnessing a progressive reintegration and reinvention of nature. It is increasingly being understood as a key structuring element in architectural and urban design. Vegetation in our surroundings is no longer an immutable scenic backdrop or a reserve for evasion. We must approach its character from a new perspective that goes beyond the purely aesthetic and functional, shaping plant systems capable of generating ecosystem services in urban and peri-urban areas. This implies opening our eyes to new ecosystems emerging spontaneously within parks and gardens, or vacant lots, residual spaces, and post-industrial fragments.
Over the years, ZARCH has demonstrated a strong commitment to environmental concerns, recognizing its vital place within architectural and urban thought. These concerns have been addressed in both individual articles and thematic issues such as No. 7 (Landscape Perspectives), No. 15 (Urban Processes, Water Dynamics, and Climate Change), or more recently, No. 23 (Peri-Urban Landscapes).
Continuing along these lines, the present issue aims to further explore, debate, and highlight the potential of the symbiosis between vegetation, architecture, landscape architecture, and urbanism. We welcome proposals and investigations that go beyond treating vegetation as a mere add-on in urban design, inviting instead a reconsideration of how we inhabit, design, and relate to plant life. This must be addressed through a transversal lens that promotes both conceptual and functional integration: conceptual, by fostering collaboration across disciplines; and functional, by establishing new interconnections between urban planning, architecture, and vegetation itself.
At the territorial and urban scale, mapping takes on a strategic dimension. Mapping the presence —or absence— of vegetation in cities and their surroundings, through analytical and representational tools capable of visualizing biodiversity, seasonal dynamics, ecosystemic flows, or multi-species relationships, can contribute to the elaboration of diagnostics and strategies. At the same time, works that explore critical re-readings of the binomial vegetation/architecture, whether from a historical or projective, political or sensorial, material or symbolic approach, can be insightful. The cartographic tool can reveal hidden potential in the territory and simulate the dynamic processes of the living landscape.
At the project scale, we are particularly interested in examining how architecture and landscape architecture might function as ecological infrastructure, not only through technical solutions. This includes buildings and public spaces designed to host non-human life forms, thresholds conceived as biological corridors, or typologies inspired by biophilia that merge with vegetated systems. These approaches offer the opportunity to rethink construction and urbanism through more inclusive and adaptive logics. In this context, we seek to investigate the role vegetation might play in shaping urban structures through richer and more complex frameworks: its integration into the built environment, its influence on urban fabrics, its contribution to spatial quality, its role in thermal comfort, and its pedagogical, productive, and social value.
Equally important is the inclusion of ruins and derelict, dismantled, or transitional structures-spaces that today offer fertile ground for both ecological and cultural regeneration. Urban planning must be capable of recognizing and incorporating these pre-existing conditions, whose symbolic, aesthetic, and functional value lies in their potential to form new ecosystems both within cities and in peri-urban territories. Hence, a territorial perspective becomes essential, opening new possibilities between interior and exterior, urban and natural domains. We especially encourage contributions that address edge spaces where biodiversity thrives. Zones where opportunistic vegetation, native or spontaneous, shape hybrid landscapes that function as ecological buffers.
Within this framework, we are also interested in research on artistic practices, community actions, and alternative pedagogies that promote the collective reappropriation of green spaces in the city. From public art to environmental activism, from self-managed parks to community gardens, from the artwork to the new perception of plant aesthetics, such initiatives generate a new urban ecological imaginary, one in which the city is no longer understood as the negation of nature, but rather as its potential ally.
From the vernacular to the visionary, from infrastructure to the sensory, from the urban core to the periphery. This issue invites transversal and multi-scalar contributions that approach vegetation and the ecosystems it embodies, not as passive resources, but as active agents that challenge our ways of designing, building, and inhabiting. The goal is to rethink our cities, considering the social and environmental challenges that lie ahead.
