Since the 1950s, cycling policy in China has gone through three phases: from active encouragement (1955–1994) and systematic discouragement (1994–2008) to neglect and ambivalence (since the 2010s). Parallel to the expansion of automobility, the country has been unique in its development of innovations in electric-powered two-wheelers and a vibrant e-cycling practice since the 1980s. Electric bikes have given over 300 million low-status commuters and peddlers access to jobs and housing, even though planners have dismissed them as a problematic ›floating population‹ and remnants of the past. Given China’s current urban sustainable mobility challenges and ambition to become the world’s first ›Ecological Civilization‹ (2013), China’s bicycle industry, e-vehicle manufacturers, and the e-commerce sector may offer an alternative to the US-based ›car civilization‹ if ecological (e-cycles) and social (low-status workers) sustainability are brought into one analytical frame.
This article examines the rise of aeromobile sprawl, which is defined here as aviation’s socio-environmental impact on people, places, and things, in Canada during the 1970s. It links aeromobile sprawl largely to state-led airport development and the effect that upgrading, expanding, and building new airports had on communities and landscapes. Accordingly, it shows that while aeromobile sprawl was to some extent an outcome of postwar developments not limited to aviation, the Canadian government and its partners also contributed to sprawl by endorsing various policies and strategies that shifted over the period in question. At the same time, these actions did not go unnoticed. Public critiques of aeromobile sprawl emerged as people increasingly objected to larger and busier airports operating near populated and non-industrial areas. This article demonstrates that debates in Canada about airport development and the rapid growth of aviation revealed sharply diverging views about how to best accommodate the mobility requirements of mass air travel within the country’s natural and built environments in the 1970s.
Stadtgeschichte
(2016)
Das 20. Jahrhundert lässt sich als „urban century” begreifen. Doch besteht bei aller Forschungsdynamik nicht wirklich ein Konsens darüber, was das Feld jenseits seines Gegenstandsbezugs eigentlich zusammenhält. Warum sind Städte gerade in jüngster Zeit zu immer prominenteren Gegenständen der Forschung geworden? Malte Zierenberg stellt Definitionsansätze vor, die zu klären versuchen, was die Stadtgeschichte eigentlich ausmacht, beschreibt interdisziplinäre Einflüsse, die für die moderne Stadtgeschichtsschreibung von Beginn an wichtig waren, und gibt einen Überblick zu aktuellen Forschungsthemen und Begriffen.
