Welcome to attend Jenny Norrman's digital popular science lecture on subsurface resources, in connection with her promotion as Professor at the Department of Architecture and Civil Engineering.
About half of the world’s population lives in
cities, and with continuing urbanisation this number is expected to
increase. With high and increasing pressure on urban land, space becomes
a scarce resource: we build denser, higher, at locations that are
contaminated or require more complex foundations and if the economy
allows, we locate suitable facilities underground.
The subsurface however, is not only a construction basis which
provides physical space and shelter for infrastructure and the
possibility to create a better surface living environment: it is a
multifunctional resource. Apart from physical space, the subsurface can
for example provide and store water, energy and materials, provide
habitats for ecosystems, act as support for surface life, and serve as a
repository for cultural and geological heritage. The subsurface can be
associated with hazards, such as naturally occurring radon, industrial
contamination, areas prone to landslides or soil subsidence. To maintain
favourable conditions in cities and efficiently plan and maintain urban
infrastructure we need to manage our land resources, including those
hidden in the subsurface, in a strategic and fair manner.
In this lecture, I will discuss the role of the urban subsurface
for achieving sustainable cities and present selected research
activities that address some of the challenges and opportunities for
urban land resources.
