A billion more people will be living in cities the next time a gavel opens the bi-decennial UN conference on housing and sustainable urban development, known as UN-Habitat (hint -- that will be in 20 years). Following this week's proceedings in Quito, Ecuador, cities will face two significant challenges between now and the next meeting in 2036.
The first is coping with the inexorable trend towards urbanization. By 2036, over 60 per cent of the world's population will reside in cities. The burgeoning number of urban dwellers worldwide will put pressure on city governments in areas ranging from housing to services, infrastructure to transportation.
The second challenge is the need to reduce greenhouse gases (GHGs) while adapting to rising temperatures.
