exploring the sustainable city of stone

In the provinces of southeastern Italy, the landscape is changing, as a new world of alternative energy infrastructure blends insular hill towns, turbines and solar panels across traditional farmland. Yet, on the same horizons other, age-old reflections of local sustainable practices echo time-honored human traditions, as lessons for urban reinvention in a networked world.

We need to discuss these lessons more often.

For two August weeks observing the cities, towns and villages of Basilicata, Molise and Puglia, I pondered how these reflections of people and place could inform American aspirations—-often rhetorical—for compact urban centers which incubate ideas and offer solutions.

On the surface, daily urban life was readily presentable as resilient urban settings, often rendered among strolling, night crowds—a public realm reflective of climate and tradition. Amid commerce and curiosity, along streets, beside buildings and as a component of cross-town strolls, American urban density advocates can easily find justification in the residual Europe they want to see: venerable town centers, captivating facial expressions, the simplicity of child’s play in streets and squares, complemented by nearby mealtime banter, often without pattern or prescription.

Yet, behind today’s compelling imagery, there is the back story of history responsible for today, including lessons from fantastical places ripe for ready reference by urbanists and futurists who drive today’s smart cities conversation.

An example is Matera, in Basilicata, currently a city of 60,000, with a unique legacy that frames a remarkable setting of almost 10,000 years of continuous human occupation. There, the history of urban ecology, from sustainability to squalor, inspired UNESCO to designate a World Heritage Site, while its old Jerusalem-like aura captured several movie directors, including Mel Gibson, who used Matera to film The Passion of the Christ.

Matera’s legacy is a place of precedent for the sustainable city of the sort I wrote about last month in myurbanist, referencing the recent summary of sustainable city characteristics by Harvard Professor Joan Busquets. in Busquets’ concise framework, the most sustainable cities integrate natural geography and systems (such as water) into the urban fabric, provide a comfortable city center and have long-lasting, flexible designs.

According to Busquets, the sustainable city is also the historical city, and in this context, Matera readily provides examples of both sustainable urban practices reusable today, as well as the consequences of failure of long-term, sustainable systems. One lesson in particular shines through: a sustainable model must be resilient in the face of population expansion, and new economies and politics in order to stand the test of time.

UNESCO has repeatedly used Matera as an educational case study. An associated Baltic Sea Project educational guide for “observing and innovating urban ecology” (portions of which are summarized here), laments how Matera’s sustainability depended on its isolation, was undone by the trade and commerce of a capitalist world, and champions its local examples as inspiration.

Ironically, Matera’s focal point, the sassi (literally “stones”) cliff dwellings, are not readily apparent on entry to town today. They are hidden, essentially as artifacts, in two urban valleys adjacent to an ancient, cave-hewn river bed below the modern city. Yet in their time, the sassi were an exemplar of sustainable practices and textbook marriage of habitation, infrastructure and ecosystem.

The sassi of Matera included dwellings which successfully adapted to both a cool, moist winter climate and hot and dry summers. Their story is one of systems integration and efficient infrastructure—the use of natural (later extended) cliff dwelling caves for food storage, housing and urban social and commercial functions. Cisterns, built into the rock underneath such dwellings, collected channeled rainwater, and non-polluted, fresh water was successfully preserved in winter for year-round use.

As a largely self-sufficient settlement of 10,000-20,000 inhabitants into and beyond the Middle Ages, Matera grew its own food supply—nearby gardens were provided by the roof of the next cliff dwelling below. Waste, wastewater and manure were recycled. Building material was comprised of the local chalk-like sandstone (tuffa), and building stone was perpetually recreated from inner extension of the caves into the cliffs. In this sustainable world, there was little need for significant means of transportation other than to and from nearby agricultural lands, and the urban form remained largely unchanged until the eighteenth century.

Then, in a century of widespread trade revival, Matera became less isolated and the sustainable systems management of habitation, food, water and waste broke down. New residents from elsewhere brought overpopulation of the sassi. The water collection system was broken and fouled by the use cisterns as dwellings for less privileged inhabitants. As water use increased, the capacity to safely conserve it was lost. Ultimately, animals lived in close quarters with humans, and waste management systems lost integrity.

Ultimately, through the advocacy of Carlo Levi’s writing in the 1950’s, Matera’s poor and crowded living conditions, low life expectancy, high infant mortality rates and disease infestation became well known. Governmental intervention forced abandonment of the sassi until the 1990s, and the relocation of over 15,000 people. Architect Pietro Laureano—known for expertise in the urban ecology of the sassi—championed the sassi’s legacy of sustainability and adaptation to the local environment, and by 1996, Matera received its UNESCO World Heritage Site designation.

As the Baltic Sea Project study concludes, in championing the local sustainability solutions of Matera, even in today’s more complex world:

The sustainable town of Matera from the past showed a balanced ecology based on low consumption of local resources and recycling. Almost no materials or food came from abroad, trade and transport was extremely limited to the surrounding agricultural land and based on land transport done by animals or people. This transport constituted at the same time the communication lines. Muscular power and wood for fire, oil for light were the scarce energy sources used. The town stayed literally unchanged and independent of external supply through hundreds of years, with very little growth in population.

Its decline as sustainable habitation came… because of rapid immigration in a period (18th Century) of growing World trade.

During the last two centuries, neither the basic population nor the political powerful landowners, traders or governors wanted the sustainability and independency continued. They wanted to profit from the market.
…

In many countries, planners and entrepreneurs have developed local urban technology, mostly green housing, zero energy buildings, electric transport systems, but also urban ecology projects for a full-scale towns or suburbs, though still local solutions.
…

Nevertheless local solutions have shown a variety of options, and the importance of using local ideas, resources and materials is inevitable. It is simply one of the fundamental components of urban ecology, as well as it is a strategy “to break through the barriers” for unsustainable urban development.

Can the principles of Matera be successfully reintegrated in a more complex world where regional, national and world markets impact local autonomy like never before? We seem to talk like they can, with carbon-neutrality goals and tool-based approaches to transportation, water, waste, power and communication systems, including energy districts, rainwater collection, urban agriculture, bioswales, innovative architectural approaches, to name but a few.

In my view we are trying to recreate the golden age of Matera on a wide, sometimes indiscriminate scale, couched in language of inspiration, rather than precedent. Yet, the sustainable cities we seek should incorporate qualities we can learn from Matera and other documented human traditions.

Don’t get me wrong. The city of the future should be dynamic and abound with the wonders of new ideas and technology aptly catalogued in this month’s special issue of Scientific American. But I suspect that its success will also be readily ascertainable from sustainable examples of the past.

confronting the urban mirror

To my mind, one of the most compelling features of a provocative urban environment is a place where people watch people—which becomes a small-scale human observatory.

Such places are often indicative of safe public environments, including active streets, corners and squares. They are particularly prevalent in cultures where neighbors readily interact, and the seams between public and private are softer than zoning setbacks, while still allowing for a private world.

From Lecce, Italy today, I am focusing on qualities of urban spaces we can learn from, rather than oft-quoted metrics or other indices of success.

The sustainable cities we seek should include small places, where, as here, when the bustle of life begins in the morning and evening, people interact with facets of the city around them.

I suspect that workable density, in the city of the future, will abound with the types of spaces readily ascertainable from cities of the past.

We need places where we sit on the edges of the public realm and look in the mirror, to be reminded of who we really are.

discerning successful elements of people, place and urbanism

On By Chuck WolfeIn everyday urbanism, pedestrianism, placemaking, sustainability, urban views, vignettes12 Comments

Nothing is better for advocates of urbanism than simple immersion in the look and feel of a successful, authentic place.

After a week of observation in the cities, towns and villages of Pugila, Italy, most notable is the age-old, multi-dimensional relationship between people and such places, especially given American aspirations—often rhetorical—for walkable and liveable cities back home.

Here, the people and place dynamic is intrinsic to climate and tradition, and naturally occurs amid commerce and curiosity, along streets, beside buildings and as a component of cross-town strolls. It can be read in faces, the simplicity of child’s play and nearby mealtime banter, often without pattern or prescription.

What elements might be isolated, and extracted for good use elsewhere?

Vignettes abound along streets and in public squares. Does a bouncing ball against a venerable door suggest certain types of urban playgrounds? Do open windows to the wind suggest building orientations that work? Do street vendors have lessons for markets and “street food” back home? What provides a sense of safety in crowds, at all times of day?

These illustrative questions suggest the power of imagery in inquiry about diverse urban settings, and only the beginning of adapting human-scale lessons from abroad to the often two-dimensional world of American urbanism.

rediscovering the road to the sustainable city

Urban integration with geography

Those of us who write about cities should be students of history and experience, and with some humility listen to scholars and the legacy of urban development from around the world. In that sense, a recent summary of sustainable city characteristics by Harvard Professor Joan Busquets provides considerable food for thought and exploration.

According to Busquets, the most sustainable cities integrate natural geography and systems (such as water) into the urban fabric, provide a comfortable city center and have long-lasting, flexible designs. His formula for a merger of geography, comfort and flexibility embraces many issues in today’s urban dialogue, such as increasing opportunities to walk and use transit, to live closer to work and to consequently increase density and the efficient use of urban space.

The comfortable city center

I take from Busquets that a sustainable city also tactfully manages the transition from rural to urban, from country to city. Today’s tools seek to enhance this symbiotic town and country relationship, from the latest regional planning efforts (as recently acknowledged by Kaid Benfield) to innovative organizations such as the Cascade Land Conservancy, which has pioneered incentives for rural conservation in return for more concentrated urban development in Washington State.

Busquets describes the sustainable city as the historical city, which to me, cries for evidence—a physical realm of the sort championed in the late Edmund Bacon’s 1967 classic, Design of Cities, looking to traditional patterned interplay between people and place than modern regulatory tools.

The flexible city on the road to the square

How did this physical transition from country to city happen in history? How was the change in surroundings designed—or not—as one approached the city center? How did streets and alleys play magical roles in guiding travelers to anticipate arrival at focal points of commerce, government and public squares? What of angles and curves, color and light, all modified by architectural features, elevations and building materials? In times of infrastructure shortfall—and absent the ability to redevelop major swaths of land—this element of implementing Busquets’ formulation of geography, comfort and flexibility risks jeopardy, but we should not lose sight of the inquiry and potential lessons learned.

Last week, when discussing “sustainable storefronts“, I suggested that highly evolved cities successfully implement universal urban characteristics from elsewhere in a local context. Other related building blocks covered earlier include third places, corners and fusion businesses.

Next week, while abroad, I’ll be looking hard at how such building blocks can fit together again in places that largely play well with their surrounding settings—in support of the successful integration of natural geography, comfort and flexibility along the way.

retaining sustainable storefronts in the urban realm

On By Chuck WolfeIn everyday urbanism, infill development, pedestrianism, placemaking, sustainability22 Comments

Vital storefronts are an indicator of urban success, while empty businesses are akin to the ruins of Pompeii.

Even when storefronts go empty, some cities find ways to simulate that all is well. False facades, community art and the look and feel of a vibrant business district often substitute for empty spaces through glass.

That’s all well and good in cities. Elsewhere, it’s a luxury left behind.

In a skeleton of a small Idaho downtown last weekend, I explored the remnants of what we now seek in bigger places: compact, mixed-use blocks with character—the neighborhood grocery and the watering spot next door. Several buildings were proudly engraved “1914” and I concluded that if airlifted to my neighborhood in 2011, they would fit in just fine.

Passersby in a pickup truck—a father and son—saw me amid the storefronts, and stopped and watched me for a moment. “Are you from around here?” asked the father. “Do you know if there is a store in town?” 

I could have said no, but instead I wanted to hint at the irony of their search for the vanished vitality of where we were. “Look around,” I said.  “You’ll find that there used to be more than one.”

The storefront may now be scarcer in the hinterlands, but it has found new life as one of the building blocks of the reinvented, more flexibly-zoned city—a primary contributor to complete streets, social interaction, walkable neighborhoods and transit-oriented central places. The passion for such “first floor retail” has been declared and codified in planning goals and land use regulations alike.

Rockville, Maryland’s town center storefront design guidelines are typical of such emphasis, and further encourage creativity in how storefronts present to the street:

Rockville’s “great urban place” sets the stage upon which the storefronts will be
layered. Because of the investment in quality for all aspects of Rockville Town Center, storefront guidelines encourage creative and well-designed individual expressions of tenant identity. Strong urban storefronts are essential in the creation of an attractive and exciting, dining, shopping, and leisure environment.

Highly evolved cities rise above the status quo by seamlessly implementing a universal urban characteristic in a local context, seizing opportunities that have worked before to create the magnetism of success.

However, the romance of an idea can be offset by the reality of the Great Recession—and risks recreating the unsustainable place where passersby ask pedestrians if there is a store in the neighborhood. Recognizing such risks, in Seattle, a regulatory reform roundtable has recommended that certain street level retail requirements be relaxed, to avoid more empty spaces in challenging times.

Storefronts have always made the city, and as economic challenges continue, more flexibility to create dynamic and interesting street uses should remain at the forefront of city-making—mindful of what businesses need to survive.
