At the Airbus PhD workshop that I attended a couple of weeks ago [see my post entitled Making Engineering Work for Society on September 13th 2017], Axel Flaig, Head of Airbus Research and Technology, gave us an excellent opening presentation describing their vision for the future. Besides their vision for the next generation of passenger aircraft with reductions in CO2, NOx and noise emissions of 75%, 90% and 65% respectively against 2000 levels by 2050, they are also looking at urban air mobility. We have 55 megacities [cities with a population of more than 10 million] and it is expected that this will increase to 93 by 2035 [see my post entitled ‘Hurrying Feet in Crowded Camps’ on August 16th, 2017]. These megacities are characterized by congestion and time-wasted moving around them; so, Airbus is working on designs for intra-city transport that takes us off the roads and into the air. Perhaps the most exciting is the electric Pop.up concept that is being developed with Italdesign. But, Airbus are beyond concepts: they have a demonstrator single-seater, self-pilot vehicle, the Vahana that will fly in 2017 and a multi-passenger demonstrator scheduled to fly in 2018.
Soon, we will have to look left, right and up before we cross the road, or maybe nobody will walk anywhere – though that would be bad news for creative thinking [see my post on ‘Gone Walking’ on 19th April 2017], amongst other things!
Five years ago I wrote about the potential ‘Population Crunch‘ [September 15th, 2012] that could lead to a large increase in the size and number of cities – perhaps upto 1500 new cities emerging over the next few decades as the global population rises from 7.6 billion to 9.8 billion by 2050 [see UN revised report, 2017]. It is a significant challenge to provide an acceptable quality of life to the citizens of these new cities as well as existing ones. People have been concerned about the density of population in cities and its impact on individuals for more than a century. In 1910, W.H. Hudson in ‘A Shepherd’s Life’ [Penguin Books, 1910] wrote, somewhat tongue-in-cheek, about London: ‘Some over-populated planet in our system discovered a way to relieve itself by discharging its superfluous millions on our globe – a pale people with hurrying feet and eager, restless minds, who live apart in monstrous, crowded camps, like wood ants that go not out to forage for themselves’ Nothing seems to have changed!
While we were walking in the Lake District [see my post ‘Gone Walking’ on April 19th, 2017] I read ‘The Shepherd’s Life’ by James Rebank. Rebank describes how his flock is hefted to the land. ‘Heft’ is a word used in Northern England and Scotland, and means to become accustomed and attached to an area of pasture. In our modern society people tend to become accustomed and attached to cities. A few weeks earlier Nilanjana Roy, writing in the FT Weekend on April 8/9, wrote about the growing belief that national identity is an outdated and insufficient concept, whereas cities reflect the common identities of their inhabitants and have been home to peoples of diverse origin and belief for centuries. Many of us who travel frequently have a map in our heads of cities in which we feel comfortable, happy to return, accustomed or ‘hefted’. Roy calls it ‘a map of belonging’ – the cities that your spirit chimes with the most. Mine would probably include Liverpool, Ottawa, Santa Fe and Taipei [see my posts entitled ‘Out and about‘ and ‘Crash in Taipei: an engineer’s travelogue‘ on December 7th, 2016 and November 19th, 2o14 respectively]. To which cities do you feel ‘hefted’?
