Jane Jacobs, OC, O.Ont (May 4, 1916 – April 25, 2006) was an American-born Canadian urbanist, writer and activist. She is best known for “The Death and Life of Great American Cities” (1961), a powerful critique of the urban renewal policies of the 1950s in the United States. The book has been credited with reaching beyond planning issues to influence the spirit of the times.
Along with her well-known printed works, Jacobs is equally well known for organizing grass-roots efforts to block urban-renewal projects that would have destroyed local neighborhoods. She was instrumental in the eventual cancellation of the Lower Manhattan Expressway, and after moving to Canada in 1968, equally influential in canceling the Spadina Expressway and the associated network of highways under construction.
Works:
Jane Jacobs spent her life studying cities. Her books include:
The Death and Life of Great American CitiesThe Death and Life of Great American Cities is her single-most influential book and possibly the most influential American book on urban planning and cities. Widely read by both planning professionals and the general public, the book is a strong critique of the urban renewal policies of the 1950s, which, she claimed, destroyed communities and created isolated, unnatural urban spaces. Jacobs advocated dense, mixed-use neighborhoods and frequently cited New York City’s Greenwich Village as an example of a vibrant urban community.
Robert Caro has cited it as the strongest influence on The Power Broker, his legendary biography of Robert Moses, though Caro does not mention Jacobs by name even once in the book despite Jacobs' battles with Moses over his proposed Lower Manhattan Expressway.
Beyond the practical lessons in city design and planning that Death and Life offers, the theoretical underpinnings of the work challenge the modern development mindset. Jane Jacobs adheres to inductive, nearly scientific, reasoning. Moreover, she is open to anecdotal evidence coming to bear on what has been induced from harder data.
The Economy of CitiesThe thesis of this book is that cities are the primary drivers of economic development.
Jacobs' main argument is that all economic growth derives from urban import replacement. Import replacement is when a city begins to locally produce goods which it formerly imported, e.g., Tokyo bicycle factories replacing Tokyo bicycle importers in the 1800s. Jacobs claims that import replacement builds up local infrastructure, skills, and production. Jacobs also claims that the increased produce is exported to other cities, giving those other cities a new opportunity to engage in import replacement, thus producing a positive cycle of growth.
In an interview with Bill Steigerwald in Reason Magazine (06/01), Jacobs said that if she is remembered for being a great intellectual she will be remembered not for her work concerning city planning, but for the discovery of import replacement. However, her ideas are similar to those that had begun to be advanced earlier about import substitution by scholars such as Andre Gunder Frank.
The book also advances a new argument that cities preceded agriculture, rather than the reverse, which was archaeologists' previous belief. Archaeologists believed that cities required a food surplus to support specialist workers, thus requiring an existing agricultural economy. Jacobs claims that instead, cities already existed as permanent trading centers, and discovered agriculture through trade in wild animals and grains, and then disseminated agriculture to rural areas.
Cities and the Wealth of NationsBeginning with a concise treatment of classical economics, this book challenges one of the fundamental assumptions of the greatest economists. Classical (and Neo-classical) economists consider the nation-state to be the main player in macroeconomics. Jacobs makes a forceful argument that it is not the nation-state, rather it is the city which is the true player in this world wide game. She restates the idea of import replacement from her earlier book “The Economy of Cities”, while speculating on the further ramifications of considering the city first and the nation second, or not at all.
The Question of Separatism: Quebec and the Struggle over Sovereignty-Association“ In 1979 and 1980, Jane Jacobs reached the conclusion that Quebec sovereignty was necessary because of her understanding of how cities emerge and how they influence the development of nations. She looked specifically at Montreal and Toronto and foresaw the regionalization of Montreal, making it into a sort of feeder for Toronto as regional airports are to a hub. ‘In sum,’ she wrote, ‘Montreal cannot afford to behave like other Canadian regional cities without doing great damage to the economic well-being of the Québécois. It must instead become a creative economic centre in its own right… Yet there is probably no chance of this happening if Quebec remains a province.’ ”
Systems of SurvivalSystems of Survival: A Dialogue on the Moral Foundations of Commerce and Politics moves outside of the city, studying the moral underpinnings of work. As with her other work, she used an observational approach. This book is written as a Platonic dialogue. It appears that she (as described by characters in her book) took newspaper clippings of moral judgements related to work, collected and sorted them to find that they fit two patterns of moral behaviour that were mutually exclusive. She calls these two patterns “Moral Syndrome A”, or commercial moral syndrome and “Moral Syndrome B” or guardian moral syndrome. She claims that the commercial moral syndrome is applicable to business owners, scientists, farmers, and traders. Similarly, she claims that the guardian moral syndrome is applicable to government, charities, hunter-gatherers, and religious institutions. She also claims that these Moral Syndromes are fixed, and do not fluctuate over time.
It is important to stress that Jane Jacobs is providing a theory about the morality of work, and not all moral ideas. Moral ideas that are not included in her syndrome are applicable to both syndromes.
Jane Jacobs goes on to describe what happens when these two moral syndromes are mixed, showing the work underpinnings of the Mafia and communism, and what happens when New York Subway Police are paid bonuses here — reinterpreted slightly as a part of the larger analysis.
The Nature of EconomiesThe Nature of Economies, also in Platonic dialogue form, and based on the premise that “human beings exist wholly within nature as part of the natural order in every respect” (p ix), argues that the same principles underlie both ecosystems and economies: “development and co-development through differentiations and their combinations; expansion through diverse, multiple uses of energy; and self-maintenance through self-refueling” (p82).
Jacobs’ characters then discuss the four methods by which “dynamically stable systems” may evade collapse: “bifurcations; positive-feedback loops; negative-feedback controls; and emergency adaptations” (p86). Their conversations also cover the “double nature of fitness for survival” (traits to avoid destroying one’s own habitat as well as success in competition to feed and breed, p119), and unpredictability including the butterfly effect characterized in terms of multiplicity of variables as well as disproportionality of response to cause, and self-organization where “a system can be making itself up as it goes along” (p137).
Through the dialogue, Jacobs’ characters explore and examine the similarities between the functioning of ecosystems and economies. Topics include: environmental and economic development, growth and expansion, and how economies and environments keep themselves alive through “self-refueling”. Jacobs also comments on the nature of economic and biological diversity and its role in the development and growth of the two kinds of systems.
The book is infused with many real-world economic and biological examples, which help keep the book “down to earth” and comprehensible, if dense. Concepts are furnished with both economic and biological examples, showing their coherence in both worlds.
One particularly interesting insight is the creation of “something from nothing” — an economy from nowhere[citation needed]. In the biological world, free energy is given through sunlight, but in the economic world natural resources supply this free energy, or at least starter energy. Another interesting insight is the creation of economic diversity through the combination of different technologies, for example the typewriter and television as inputs and outputs of a computer system[citation needed]: this can lead to the creation of “new species of work”[citation needed].
Dark Age AheadPublished in 2004 by Random House, in Dark Age Ahead Jacobs argued that “North American” civilization showed signs of spiral of decline comparable to the collapse of the Roman empire. Her thesis focused on “five pillars of our culture that we depend on to stand firm,” which can be summarized as the nuclear family (but also community), education, science, representational government and taxes, and corporate and professional accountability. As the title suggests, her outlook was far more pessimistic than in her previous books. However, in the conclusion she admitted that, “At a given time it is hard to tell whether forces of cultural life or death are in the ascendancy. Is suburban sprawl, with its murders of communities and wastes of land, time, and energy, a sign of decay? Or is rising interest in means of overcoming sprawl a sign of vigor and adaptability in North American culture? Arguably, either could turn out to be true.”
