3. Cities of the industrial age have:
experienced unprecedented economic
crises followed by waves of out-migration;
suffered from violent destruction, made
possible by the mechanization of war;
they have been drained by
suburbanization driven by an industrialized
building sector and increasing private car
ownership;
they have undergone processes of
deindustrialization followed by losses of
workplaces and population.

25. ‘Current trends in population growth
and global environmental change will
result coming decades to
◦ population displacements,
◦ forced migrations, and
◦ abandonment of settlements
on scales previously unseen.’
McLeman, 2011:
CONCLUSIONS

26. Development of Artificial LandPotential for environmentally
related migration is rising.
Population growth rates are
highest in regions where are acute:
• resource depletion,
• land degradation,
• and the expected impacts of
anthropogenic climate
change.
As the number of settlements
experiencing a heightened state
of vulnerability grows, increasing
numbers of people will undertake
adaptive migration. In some
locations this will lead to
population decline
