‘We
face a major economic crisis
and we face a still bigger climate
crisis and by thinking through
clearly and carefully, and acting
quickly, we can respond to both of
them at the same time.
Lord Stern, January 2009

Climate change: the biggest global health
threat of the 21st century
“Managing the health effects of climate change”
Lancet/UCL Commission (16 May 2009)
 Key areas of impact
– patterns of disease and mortality
– food security
– water and sanitation
– shelter and human settlements
– extreme events
– population migration
11
What’s good for people’s health is good for
the planet too
 “We must develop win–win situations whereby we
mitigate and adapt to climate change and at the
same time significantly improve human health and
wellbeing. There are major health benefits from
low-carbon lifestyles, which can reduce obesity,
heart and lung disease, diabetes and stress.”
Professor Anthony Costello (UCL Institute for Global Health)

Health, well-being climate change

Different parts of the UK will be affected in different ways and the social
impacts may well be more pronounced in more economically vulnerable
areas.

Disproportionate effect on the vulnerable in society – the elderly, the poor,
those with less choice to avoid poorer quality internal and external
environments. Particularly severe direct impacts include
–
–
–
–

Urban heat island effect – overheating
Fuel and energy insecurity
Surface water flooding
Reduced air quality
A report by the Roundtable on Climate Change and Poverty in the UK
emphasises the interconnectedness between climate change and poverty –
and that it is possible to tackle both together.

Links between quality of public space, health and well-being
Value for exercise
unquestionable
MIND ‘Ecotherapy’ should be recognised as a
clinically valid treatment for mental distress (2007)
74% of people believe parks and open
spaces are important to people’s health
and well being
19
Proving the links between quality of public
space, well-being and health
 Overall, research presents a clear positive relationship between
green space, well-being and health.
 BUT: evidence base as a whole is highly variable
- Self-reported data limiting value
- Findings can’t support cause and effect, correlations only
- Limited use of objective measurements in physical exercise
studies
- Findings not transferable outside specific study context

 Future Health (provisional title)

being and sustainability

Making green spaces deliver more
 Importance of a strategic approach - green
infrastructure for environmental and social
benefits
 Do we have the information to support this
approach?
22
Making the most of existing data and
developing the evidence base


Initial scoping study
‘Green and Pleasant’ research:
1. Creating a baseline of evidence
of the current state of England’s
urban green space
2. Mapping and understanding the
links between deprivation, race
and ethnicity and quality of
urban green space
23
The ‘state’ of England’s urban green spaces
 Inventory of over 17,000 spaces in 154 urban local
authorities
 Indicators around 6 themes: quantity, quality, use,
accessibility, management and maintenance and
value
 14 core indicators as a baseline for future trends
 Data gaps and limitations
24
Some of the barriers to defining the
country’s urban green spaces
 No single, national indicator or dataset on quality
 Cleanliness or maintenance information only
 No dataset of quantity
 Deciding specific bundles of characteristics
 Combination of objective and subjective indicators
 Difficult to isolate the impacts
 Measurability and data availability driving definitions
of quality of life and quality of public space
25
Barriers continued….
 Acute lack of skills e.g. 68% said a lack of
horticulture skills is affecting service delivery
 Shortage of professionals such as landscape
architects and green space managers
 Collecting data is like eating your greens!
 Shortage of directly applicable National Indicators

Aspirations for public space






1. Clean: a clean and well cared-for place
2. Accessible: a place that is easy to get to and move through
3. Attractive: a visually pleasing place
4. Comfortable: somewhere that is pleasant to spend time in
5. Inclusive: a place that is welcoming to all
6. Vital and viable: a place that is well used in relation to its
predominant function(s)
7. Functional: a place that functions well at all times
8. Distinctive: somewhere that makes the most of its character
9. Safe and secure: somewhere that feels safe from harm
10 Robust: a place that stands up well to the pressures of everyday
use

Moving beyond the urban centres - where
the quality dips

31
A question of equity
 How is quality of urban green space important and
significant to health and well-being in people from
white British and black and minority ethnic groups
living in deprived areas of England?
 What is the impact of varying quality in urban
green space on well-being in these areas?
 What are the implications of these findings for
policy makers?

Selecting areas to explore these
relationships
 6 case study areas in England: London, West Midlands and
North West
 On the ground audits of green space
 Facilitated face to face household questionnaire and focus
groups
 Largest survey of its kind in UK
34
Tiers of analysis
Environmental audits of local green spaces
 Community group and independent evaluators
 Site visits and appraisals
Survey approaches
 Conjoint analysis of urban green space relative to other
environmental attributes
 Exploring relations across self-perceptions of well-being,
perceived quality and use of local green space
35
Issues for consideration
 Whether there are convergent similarities or
significant differences between ethnic groups?
 Whether our assumptions hold for what is
significant and important to particular
communities?
 How this might affect the need and provision for
certain types of green space and the implications
for more responsive management.
