Planners
will need to develop not just new lands, but also new uses for existing spaces,
as the world becomes increasingly urban. Transcript of radio broadcast.
Over half the world's people now live in
cities. The latest "Global Report on Human Settlements" says the
historic change took place last year. The report came out this week from U.N.
Habitat, a United Nations agency.
A century ago, less than five percent of all
people lived in cities. By the middle of this century it could be seventy
percent, or almost six and a half billion people.
Already three-fourths of people in developed
countries live in cities. Now most urban population growth is in the developing
world.
Urbanization can lead to social and economic
progress, but also pressure on cities to provide housing and services. The new
report says almost two hundred thousand people move into cities and towns each
day. It says worsening inequalities, driven by social divisions and differences
in wealth, could lead to violence unless cities plan better.
Another issue is urban sprawl. This is where
cities expand into rural areas, sometimes at a much faster rate than urban
population growth.
Sprawl is common in the United States. Americans
move a lot. In a recent study, Art Hall at the University of Kansas found that
people are moving away from the major cities to smaller cities. He sees a trend
toward "de-urbanization" across America.
But urban economies still provide possibilities
that rural areas do not.
Sabina Deitrick at the University of Pittsburgh,
in Pennsylvania, is an expert on cities. She notes that urbanization brings
social change that can empower women.
SABINA DEITRICK: "Women entering the labor
force is one big change and that always goes up with urbanization and certainly
will proceed in many, many countries where urbanization is increasing
rapidly."
Sabina Deitrick has closely studied Pittsburgh
from the loss of its main industry, steel, to its rebirth as a smaller city
with different industries. She says the reuse of existing land and spaces and
the reinvention of urban life is important if cities are to succeed.
Professor Deitrick notes that a city's ability to
educate and train its people is important to jobs and new industries. Even new
industries based on old ideas.
Around the world, people leave rural farm jobs to
go to the city. Yet now there is growing demand for farm products grown close
to the cities where they are used. Urban farming is taking hold in some of the
world's biggest cities. Sabina Deitrick says studies show that urban farming is
one area where woman can earn more than men do.
And that's the VOA Special English Economics
Report, written by Mario Ritter. I'm Steve Ember.
