| Summary: | Globally, cities are the source of over
70 percent of the world's greenhouse gas emissions.
Cities are also the engines of the global economy,
concentrating more than half the world’s population, and
they are where the middle class is rapidly expanding.
Indeed, by the year 2050, two-thirds of the world will be
urban, with cities accommodating an additional 2.5 billion
people over today’s total. Nearly all of this urban growth
will occur in developing countries. This concentration of
people and assets also means that the impacts of natural
disasters, exacerbated by the changing climate, may be even
more devastating, both in terms of human lives lost and
economic livelihoods destroyed. These effects will
disproportionately burden the poor. Earth is on a trajectory
of warming more than 1.5 degrees Celsius unless important
decarbonizing steps are taken.Often urban policymakers
prescribe integration as the solution to steering
urbanization towards decarbonization to achieve greater
global and local environmental benefits. However, little is
known about the struggles—and successes—that cities in
developing countries have in planning, financing, and
implementing integrated urban solutions. The main objective
of this report is to understand how a variety of developing
and emerging economies are successfully utilizing horizontal
integration—across multiple infrastructure sectors and
systems—at the metropolitan scale to deliver greater
sustainability. This report explores how integrated planning
processes extending well beyond city boundaries have been
financed and implemented in a diverse group of metropolitan
areas. From this analysis, the report derives models, poses
guiding questions, and presents three key principles to
provoke and inspire action by cities around the world. |
