The geography of a coastal city, such as its native geological, biological, and physical conditions, plays an important role in understanding the impacts of climate change upon the area. To better identify strategies for adaption to global climate change, planners and designers need better tools and techniques to learn and analyze the geographical context of their cities on coastlines worldwide. This article describes an urban design studio conducted in the spring of 2014. Students in this class explored the future of North Carolina coastal cities in light of rising global sea level. Geodesign using GIS and other visualization tools enabled the students to focus on urban morphology, development patterns, and environmental characteristics of the city in order to identify new interventions that can support a new set of relationships between urbanity and nature.
With the notable uptick of natural disasters impacting densely-populated areas, attention to the subject of urban resilience has increased among ecologists, economists, engineers, social scientists, and designers. But despite an extraordinary cross-disciplinary interest in a single subject, the urban resilience discourse has remained largely siloed by discipline. This essay builds on concepts of resilience from ecology and social science and positions urban design (in itself at the intersection of architecture, planning, and landscape architecture) as uniquely situated for integrating and operationalizing various concepts of urban resilience. The authors propose a socio-ecological urban design approach that bridges natural, human, and spatial systems and is empirically grounded in historical research, field observations, and interviews with informal settler families (ISFs) living along the shoreline of Laguna de Bay in Metro Manila. The findings revealed that while many were affected by regular flooding and issues of housing security, these were not necessarily deciding factors when determining where to live. In response to programs which emphasize out-of-city relocation, authors developed three principles of urban resilience that instead spatially integrate formal and informal communities.
The manuscript reflects on the delightful and absurd qualities that might be harbored in routine infrastructures. Through a series of contemporary and historical examples the paper highlights how experience, material quality, narrative, and civic engagement can unlock new potentials in the mundane, and often intangible systems, which are intended to protect and serve those in flood prone territories. Understanding first that resilient water-management infrastructures exist along a spectrum of defense, and second that they each participate in their own extensive system of flows and processes, generates a set of opportunities for designers to interject and draw out new possibilities. Locating projects within these systems calls for two approaches:
1. identifying the “objecthood” of infrastructure; and 2. techniques for “unblackboxing” or bringing parts of now hidden systems to the foreground of the civic realm. The paper suggests that these two approaches aid in locating the whimsical within systems and offer calculated ways to confront flood mitigation methods that all too often privilege what is deemed as efficient over what is enjoyable.
Climate change puts the edge between land and sea in sharp relief; sea level rise is essentially a condition of drifting littoral edges.As rising seas threaten to encroach on land-based territories, cities and nations have responded by attempting to fix the edge at a moment in time, blocking the sea’s insidious creep. Atolls formed by coral reefs are mobile, living geographies, which resist attempts to harden their perimeter through structures such as seawalls. We explore how ideas and imaginaries associated with the “edge” between sea and land in the atoll-nation of Tuvalu illustrate competing “riskscapes” and objectives associated with the actors involved. This essay explores this interplay between politics, aid, technocratic solutions, media representations, global aspirations, local ambitions, and climate risk in Tuvalu through an examination of past/future seawalls and other proposals (realized and unrealized) for controlling atoll edges. Through the cases, we seek to re-politicize the edge, unpacking the difficulties surrounding adaptation issues in small-island states, and explore alternative models of “resilient edges” for atoll-dwellers living with climate changes.
Human activity has been changing the surface of the earth for several thousand years. In recent decades, the rate of change however was accelerated in the Yangtze River Delta, propelled by China’s rapid and continually chaotic process of urbanization and industrialization. How can our cities eventually face haze, water pollution, soil contamination, and natural disasters caused by climate change? The challenge is indeed to explore how to achieve an ecological resilience by enhancing biodiversity and by reviving and revising productive landscape.
Using Rio de Janeiro as a case study in urbanization within the context of climate change, this multi-year urban design studio examines the challenges of addressing rising sea levels in one of Latin America’s largest cities. As a coastal metropolis, Rio requires that heterogeneous networks be woven between ecological and 21st century urban design processes. Yet, Rio continues to grow in low-lying, ecologically sensitive areas - and this has been exacerbated over recent decades by mega-event driven development coupled with inter-dependent informal urbanization. These forces characterize Zona Oeste, the focus area of the design initiative. This essay reflects on an international urban design pedagogy that seeks to integrate strategies to address climate change, rising sea levels, and unpredictable growth. Inherently, this project opens up a discussion into many sensitive questions regarding historical and cultural responsiveness. Filtered through the work of Lucio Costa, his proposals for Baja da Tijuca, and opportunities to re-engage the legacy of a modernist plan, students engage this rich context through a discursive design prompt with implications for both pedagogy and practice within and beyond Rio de Janeiro.
This paper originates from a Louisiana State University School of Architecture Research Studio. Charged by the organization’s Director, the students investigated the Louisiana Universities Marine Consortium (LUMCON) facility and environment, and re-imagined both the building and landscape as a cutting-edge (albeit remote) research and educational destination. “The SEA Is Coming” Integrative-Design Studio proposes adaptation to climate change as a means to investigate the transformative capacity of a site. Going far beyond the boundaries of current (and future) building program, the studio method provoked profound rethinking of current conventions about coastal change and occupancy, design, community, the environment, and land use. LUMCON’s facility sits at the nexus of deltaic land, freshwater, brackish wetland, and salty ocean and provides access to all these systems. It has withstood the volatility of this environment: flooding, hurricanes, oil spills, the Gulf dead zone, salt-water intrusion, etc. Now over thirty-years-old, the building must adapt to changing conditions. The studio investigated LUMCON’s ability to continue functioning in its changing environment and further its indispensable research capabilities of the rapidly changing coastal landscape.
In this space, small-scale coastal erosion, and natural growth become the vehicle for project based architectural speculation that leverages the resources of local landscapes and creates a new architectural trajectory based upon the need and aesthetic of ecology. Here, MaterialNature is a series of architectural entities that become landscapes over time, made from a mixture of residual materials designed specifically to be weatherized. Its design is intended to provide a potential architectural amenity in areas of recreational activity as well as areas devoid of human contact, while simultaneously realizing a potential for architecture to be born from waste or local material, and to return to nature without providing further waste. As such, this architecture moves from one of formal composition to one where the formal characteristics of local ecology and landscape become more apparent than the form itself.
Miami is a city whose diversity and vibrant growth has made it an ideal destination for international travel, business, and leisure. However, South Florida is a hurricane prone region, and the threat of sea level rise and erosion poses an immediate and long-term risk to the stability of the city and its region. The city and the scientific community have been studying the phenomenon for some time now, proposing solutions to the management of such threatening uncertainty. Yet the quest for coastal resilience is not a new phenomenon. Since ancient times human settlements have entertained a complex relationship to the water. This paper will explore how several cities throughout history have dealt with flood resilience challenges and consider how historical attempts to adapt and address such problems can provide new spatial strategies for Miami’s future. Aware of the fact that such a study cannot reveal technical solutions for the twenty-first century, the emphasis will be given to an understanding of the correlation between socio-economic identity, attitude towards defensive action, and the type of organization needed for concerted action.
Situated between several interdependent political and economic zones of southern China’s Pearl River Delta, the Pearl River Delta Special Ecological Area (PRD SEA) project explores the possibility that regional administrative boundaries could be softened and redrawn along ecological boundaries. With the advent of global sea level rise and its impact on the fragile fresh water ecology and huge population of the Pearl River Delta, the project proposes novel ways to share fresh water and wastewater across political zones to better administer and profit from the distribution of water resources.
Climate change, urbanization, and pollution from industrial and agricultural development threaten the steady supply of fresh water to the Pearl River Delta and its cities, while population growth in the region only increases demand. At the same time, Hong Kong, Macau and Shenzhen’s increasing economic, political and cultural interdependency presents the possibility to tackle these challenges holistically. Layering a regional water resource infrastructure onto existing and new industrial, residential, agricultural and transportation armatures would transcend borders and create new economic markets through ecologically sustainable practices.
“Groundedness” implies stability and permanence, but our reliance on the presumed fixity of the earth under our feet has led us to lose sight of its dynamism. From macro tectonic readjustments to micro sediment transport, these natural processes are part of an adaptive cycle that oscillates between stasis and destruction. Urban development, predisposed to Engineering Resilience, has exacerbated disasters by attempting to fix and control ground without considering the recombinant and indeterminate systems of Ecosystem Resilience. Seattle is the largest city in a region due for its “Next Big One” - a megathrust earthquake in the Cascadia Subduction Zone. This high-magnitude perturbation would occur in an urban context already sensitive to geologic risks. A history of land manipulations has affected Seattle’s ground equilibrium, making it more susceptible to natural disasters. The urgency of the impending risks has inspired adaptive design that foregrounds action as a means of developing a disposition. A catalogue of strategies is applied to a masterplan that balances “sediment” as a resource that builds resilience to ground hazards and promotes ecosystem health.
Coastal areas are an extraordinary condition for research and investigation, at a scale encompassing multiple landscapes that underwent a massive transformation, leading to their current crisis state. A landscape with different degrees of depth, with complex conditions and rules of the spatial systems that can be fully understood only through an accurate selection and study of the elements that concurred to its creation. The natural cycle that built the different elements of this landscape is definitely an element to take into account during the definition of the design strategies: through the alluvial deposit first and marine next, it “built” the shore, the dunes - a natural protection against the sea-water level rise - and the pinewood behind the dunes. Our goal is strategy that, recovering and recycling the ancient and pre-existing dialogue between the form of the city and the form of the landscape, recovers and recycles that long and natural resilience process: a quality those areas always had, considering also the potential rising of sea levels.
Utilizing the North Beach Village neighborhood in Fort Lauderdale, Florida, as case study, “Salty Urbanism” establishes an interdisciplinary team to develop a coupled research methodology and pedagogical approach that envisions and quantifies the experiential and ecological outcomes of alternative ways forward for the neighborhood in response to climate instability, disruption and rising sea levels. These outcomes consider an inevitable future of saturated landscapes and, as a result, integrate research models that accommodate a variety of best management practices (BMP), low impact development (LID), green infrastructure (GI) and other alternative concepts to be implemented over time in the neighborhood adaptation plan.
Through design-based research, we investigate how a water-borne micro-city can participate in ecological repair that also supports healthy, human life by removing harmful algae from the water and utilizing it as a supply resource for energy. In this proposed scenario, urbanism becomes the active component in prevention of toxic algae blooms. By bringing together scientific research with research from medicine, design, history and social science, we begin to animate design strategies that promote local and regional resiliency within the Great Lakes. These hypothetical designs, while focusing on algae within the Great Lakes, can provide a feasible prototype for other coastal regions around the world. The priorities of this project are relatable to all coastal-adjacent settlements and the pending depletion of resources that will jeopardize human life.
Contemporary architectural ornament serves multiple purposes; articulated surfaces are no longer simply symbolic gesture but, in addition, contain material performance as expression of technological, environmental and other cultural factors. At the same time, parametric design has opened new frontiers in patterning and bio-inspired design.
The manifestation of these bio-inspired materials can be compelling spatial narratives that speculate on the blending of nature and architecture. However, these biophilic tendencies might further serve in the development of more sustainable architecture and urbanism; surfaces and structures derived from nature might also serve nature.
In this work, we present a method to define “habitat grammars” that create functional spaces for diverse species, as well as generating unique aesthetic properties derived from regional nuances in flora and fauna. The method is applied to a seawall in South Florida near mangroves. Panels were cast in high strength concrete and experimentally observed in aquariums with live specimens. The results indicated that low relief panels performed equivalent to featureless walls, whereas higher relief panels elicited a near unanimous response from the introduced species.
The increasing hydro-morphological and environmental degradation of lagoon systems is an issue shared by many Mediterranean contexts. A Selective Retreat Strategy could be a radical solution for these sites, in order to better manage the investments and maximize the efforts on some specific settings, deliberately omitting others. This approach comes from a research program developed by Sealine (Ferrara University) on the delta of the Po River. Such lagoon system is highly unstable, vulnerable to intense dynamics (coastal erosion, subsidence, saltwater intrusion, etc.) affecting both its ecological value and the human activities taking place around it (agriculture, fishing, aquaculture, tourism). The infrastructural effort to freeze its evolution is no longer maintainable and increasingly less efficient, given the site dimension and complexity. Besides these remarks, such proposal is encouraged by specific boundary conditions like the low productivity of farming areas and the land ownership arrangements based on few big properties. Therefore, it is possible to envisage a progressive site reorganization according to its historical character of evolving landscape shaped, over the centuries, by the alternation of natural phenomena and human interventions.
The waterfront along the San Francisco Bay is facing a growing threat from sea-level rise. By the end of the century, a projected sea-level rise of 55 in. [140 cm] will affect an estimated 128 sq. mi. [331 km2] of urban development valued at $62 billion. In addition, 2.1 million people and 660,000 homes are estimated to arrive by 2040, adding to the 7 million current Bay Area residents. Furthermore, sea-level rise will affect the ecology of the San Francisco Bay, threatening to submerge the majority of existing tidal wetlands by mid-century. To combat sea-level rise, many are calling for increased shoreline protection, while others suggest the removal of urban development in areas at risk of inundation, allowing tidal wetlands to migrate to higher elevations. In this proposal, I demonstrate that both may be accomplished by a managed retreat of existing development, enabling wetland migration, while introducing a resilient new typology of development built on levees that is designed to co-exist with a tidal ecosystem, enabling new relationships between urban life and bay ecology that redefine the coastal boundary.
The notion of the resilient edge is perhaps most emblematic in deltaic landscapes, which are a landscape form par excellence of edge conditions - both for their fluctuating natural boundaries and complicated relationship with anthropogenic forces. Given this juxtaposition, it is worthwhile to revisit the early history of deltaic transformation and urbanization — from surfaces to edges — to gain insights into the future resilience of these landscapes and strategies for their redesign. In this essay, we investigate the early history of the California Delta, starting with the Swamp Lands Act of 1850, to gain insights into how policy and technology territorialized this vast inland estuary. We then reformulate this history as a contemporary strategy for the design of deltaic landscapes and introduce a pedagogical experiment to test our observations.
The development of a landscape architecture project that contains a scientific research and tourism station is being considered in an extreme territory – dynamic, isolated, hard to access - in Exploradores, western Aysén, southern Chile. The territorial characteristics, lack of infrastructure, and limited information about the place to be intervened into mean that its landscape – the subject of this work- is hard to define. This situation leads the research into the development of a first part – analytical, descriptive, and speculative - which will define the remote landscapes of Exploradores, which are not observed physiologically in the territory.
The first part will be complemented by the landscape architecture project, which proposes, by architectural insertions, to interpret and express the situation that has been recognized. Supported by a methodology that studies the territory with a four-scale approach, representative aspects of the local landscape will be determined that seek to function as an operative tool guiding decisions for the project.
How do we treat those who make mistakes? And what does this have to do with architecture? The paper will investigate the role of architecture in the design of prisons in order to understand how we could develop a project for a jail that is a place for both punishment and rehabilitation. The effectiveness of a prison is not given only by the efficiency of the justice system in force, but also by the articulation of spaces and by the quality of the architecture. The contradiction of the prison is revealed by its need to respond to two opposing demands: punishment and reintegration. This paper investigates the possible design approaches aimed at designing a new jail typology, through an attempt to "break" the macro-themes that characterize the building of the prison and within these dichotomies work on the "boundary-line" between opposing realities: freedom―constriction; openness―closure; etc. If prison architecture were brought back into the debate regarding contemporary design culture, it could have a significant impact for society especially in terms of opportunities and cultural growth.
For centuries, measured drawings have been the major communication medium to acquire an understanding of the built environment and to deliver ideas of construction and design. The value of measured drawings as educational tools to learn about the architectural context as well as signifiers of the cultural values have transcended the importance of these two-dimensional illustrations as ephemeral depictions of building forms and materials. In the midst of an architectural culture increasingly utilizing three-dimensional virtual surrogates along with the state-of-the-art surveying and representation methodologies, however, the production of measured drawings have been relegated to a narrower focus in the documentation projects. The methodological path to produce measured drawings carries similar traits with how ethnographers create thick descriptions of cultural signifiers. Reflecting on measured drawings as an account of “thick description,” this essay addresses architectural documentation.
The research addresses the topic of intermodality in terms of technical, typological, and architectural response of infrastructure systems, considering their relationship with the territory and the landscape. The study starts from the hypothesis of the development of a comprehensive intermodal hub in the Ronchi dei Legionari Airport (Friuli-Venezia Giulia, Trieste, Italy), integrated with the network of local public transport and railway infrastructure, considered in a scenario of sustainability over the medium term and updated with respect to the current economic situation. The first phase of the research focused on the definition of the guidelines for the design of the intermodal hub. Subsequently, the study verified the hypothesis by modeling some alternative scenarios, whose results led to the identification of a highly comprehensive set of data, consistent with the financial framework. Lastly, urban verification: the identified scenarios constitute a framework of alternative options corresponding to the minimum, optimal and critical conditions of the system as a whole. The possible alternatives prove the degree of versatility of the proposed layout which provides, as a whole, the possibility of opting for one of the proposed scenarios or for a more complex combination of the proposed solutions.
The estate Las Heras lies close to Girona in Spain. I was taken there by my client, in the form of a mystery tour. We arrived at a large house within 350 hectares. I felt instant affinity to this place before leaving the car. I asked my client: “Why did you buy this?” He answered: “…that is YOUR project – to tell ME!”
The land exuded a sense of place which appeared irrational. Time and neglect had taken its toll on the main house and work began to repair the building.
The estate has a long and tumultuous history; the past informs the present and creates context for the experience of the place. The future required a possible description. A narrative (novella) was an indulgence that allowed exploration of what might happen in the formation of the place. The book exists as a plan, a gazetteer volume of information, and a cookbook, intended to stimulate and encourage.
The emerging project’s starting point is as an educational resource for anyone; particularly for architectural and art institutions.
