Urban areas and quality of life
For the three-quarters of Europe’s population that live in cities and towns, a good urban environment is a precondition for a good quality of life. It seems, in part, that over the last decade, attitudes to living in cities have been changing. People are no longer moving away from cities (or have returned to them), residential sprawl has slowed and, in a third of cities, the population is concentrating in city centres. These are some of the findings in the report: Urban environment – SOER 2010 thematic assessment.
The environmental elements of good quality of life
As the major function of cities is to provide places for people
to trade, produce, communicate and live, the urban environment
needs to be assessed from a very specific human perspective:
to provide an agreeable place to live while minimising or balancing
negative side effects.
Quality of life in cities relies on a range of components such as
social equity, income and welfare, housing, a healthy environment,
social relations and education. The environmental elements of good
quality of life include good air quality, low noise levels, clean
and sufficient water, good urban design with sufficient and
high-quality public and green spaces, an agreeable local climate or
opportunities to adapt, and social equity. However, urban-specific
data are patchy in Europe and, due to different timescales and
reporting methods, are seldom directly comparable.
Urban challenges
Many of our cities struggle to cope with social, economic and
environmental problems resulting from pressures such as
overcrowding or decline, social inequity, pollution and traffic.
The environmental impacts of cities also spread well beyond their
physical limits as they rely heavily on outside regions to meet
demand for energy and resources and to accommodate waste. A study
of Greater London estimates that London has a footprint 300 times
its geographical area — corresponding to nearly twice the size of
the entire UK.
Climate change
Climate change has the potential to influence almost all
components of the urban environment and to raise new, complex
challenges for the quality of urban life, health and urban
biodiversity. Some cities will experience droughts and higher
temperatures. Others will experience floods. Climate change will
affect many aspects of urban living from air quality to consumption
patterns (e.g. energy for air conditioning).
Poor urban design can aggravate the impacts of climate change. Soil
sealing, for example, can increase the ‘urban heat island effect’.
It may also increase water run-off and lack of drainage during
heavy rains leading to floods. However, urban design aimed at
tackling climate change could have numerous co-benefits from
improved air quality, supporting biodiversity and quality of life.
Urban opportunities
The proximity of people, businesses and services associated with
the very word ‘city’ means there are also huge opportunities and
benefits associated with urban living especially in terms of
sustainability and resource use. Already, population density in
cities means shorter journeys to work and services, greater use of
walking, cycling or public transport, and living in apartments of
multi-family houses or blocks requiring less heating and less
ground space per person. As a result, urban dwellers on average
consume less energy and land for living per capita than rural
residents.
Designing the future
Cities are ecosystems: they are open and dynamic systems which
consume, transform and release materials and energy; they develop
and adapt; and they interact with humans and with other ecosystems.
They must therefore be managed and protected like any other type of
ecosystem.
Through rethinking urban design, architecture transport and
planning, we can turn our cities and urban landscapes into ‘urban
ecosystems’ at the forefront of climate change mitigation (e.g.
sustainable transport, clean energy and low consumption) and
adaptation (e.g. floating houses, vertical gardens). Furthermore,
better urban planning will improve quality of life across the board
by designing quiet, safe, clean and green urban space. It will also
create new employment opportunities by enhancing the market for new
technologies and green architecture.
Cities, due to their concentration of people and activities, matter
for Europe. Also, the problems of cities cannot be solved at the
local level alone. Better policy integration and new governance,
involving closer partnership and co-ordination at local, national
and European level, are required.
