Sustainable development goal 11: make cities and human settlements inclusive, safe, resilient and sustainable
The speed of population growth is rapidly
far beyond our imagination. The amount of people living the city is more than that
of countryside. By 2015, there are nearly 4 billion people, 54% of the world`s
population, will live in city. This figure will reach 5 billion by 2030. The rapid
irrational urbanization brings numerous serious issues, including the growth of
slum dwellers, increasing air pollution, inadequate basic service and
infrastructure.
The proportion of urban population living slum
has declined by 20% since 2000, but the absolute number continue to grow.
The speed of urban land expansion is faster
than the population growth(irrational suburb sprawl )
The rate of waste served by municipal waste
system is only 65%
