Adapting the city
Safeguarding Communities
• All Greater Manchester neighbourhoods will be affected
by a changing climate.
• Some more affected by others: vulnerable communities
disproportionally.
• Consequences of both a changing climate locally and a
changing climate elsewhere.
• Likely impacts include; floods & drought; health &
wellbeing at home and work, disruption, supply and
security of services.
• Long term change: short term action.

Impacts of weather & climate on people and
communities
Floods (55%), storms (14%), cold (12%) and heat (7%) have the greatest
consequences on health & wellbeing in GM

Whilst consequences for heath and wellbeing due to cold are likely to
decrease, flooding and heat consequences are likely to increase

Projected increase in climate hazards
E.g. Heatwaves & flooding
Vulnerability of people & communities
to climate change
• People have different capacity to deal with hazards
• So therefore not everyone is affected to the same extent
• Coping capacity is dependant on:
• Access to information – social networks; language
• Ability to prepare for flooding / heat – resources e.g. insurance
• Capacity to act in the case of emergency – knowledge; ability
• Ability to recover after flooding – resources; physical & mental
strength
Spatial distribution of vulnerability
Poverty & poor health
Diverse, transient communities
• Four principal groups
• High scores of poverty and
diversity components
concentrated around urban
centres
Families with children
High percentage Elderly
• High scores of children
component located in
sub- and peri-urban areas
• High scores of old age
component more scattered

Summary: Key messages
• Climate change hazards affect people and communities in
Greater Manchester
• Heat waves & flooding events are likely to increase in the future
• Spatial distribution of vulnerability and reasons for
vulnerability varies
• Poor & diverse communities are the most exposed to risks
(where risk is a function of location, vulnerability, land cover,
housing, etc.)
• Adaptation requires actions e.g. physical environment,
community development, social infrastructure, green infrastructure…

How does climate change affect health?
Climate change undermines the environmental
determinants of health
Without effective responses, climate change will compromise:
Water quality and quantity: Contributing to a doubling of people
living in water-stressed basins by 2050.
Food security: In some African countries, yields from rain-fed
agriculture may halve by 2020.
Control of infectious disease: Increasing population at risk of malaria
in Africa by 170 million by 2030, and at risk of dengue by 2 billion by 2080s.
Protection from disasters: Increasing exposure to coastal flooding by a factor
of 10, and land area in extreme drought by a factor of 10-30.
How does climate change affect health?
The time is now
Deadly heat wave holds firm in Europe
Temperatures throughout Europe continued above normal, as France
reported as many as 3,000 deaths due to the heat
Difference from normal temperatures Aug 3 to Aug 9 2003
3,500 died prematurely
as a result of Europe’s
heat wave in 2003

What affects infection/health risks in a drought
period?
Risk of cryptosporidiosis
Lack of dilution of sewage effluent
Opening up of rapid transmission routes between surface and groundwater
through low water table
Heavy rainfall after the drought providing a bolus of contamination

Housing
• EWDs are almost three times higher in the coldest quarter of
housing than in the warmest quarter (21.5% of all EWDs are
attributable to the coldest quarter of housing, because of it being
colder than other housing).
• Children living in cold homes are more than twice as likely to
suffer from a variety of respiratory problems than children living
in warm homes.
• Mental health is negatively affected by fuel poverty and
cold housing for any age group.
• More than 1 in 4 adolescents living in cold housing are at risk of
multiple mental health problems compared to 1 in 20
adolescents who have always lived in warm housing.
• Cold housing increases the level of minor illnesses such as
colds and flu and exacerbates existing conditions such as
arthritis and rheumatism.

Health system strengthening:
Definition of an essential public health package
Most health risks in next 20-30 years could be averted through:
• Comprehensive assessments of climate risks to health and health systems;
• Integrated environment and health surveillance;
• Delivery of preventive and curative interventions
for identified climate-sensitive public health concerns;
• Preparedness and response to the public health
consequences of extreme weather events;
• Applied research; and
• Strengthening of human and institutional capacities
and inter-sectoral coordination.
What has been done? Health system strengthening
Food Security and Supply
Dr Angela Coulton
Food Security
• UK and global pressures on the food system
• City perspectives and action on food
• Developing Manchester’s response
A Perfect Storm? Pressures on the UK Food System
• Climate change scenarios of 2-4 degrees by 2050– significant
impacts on agricultural productivity in UK and worldwide.
• Increasingly resource intensive diets in developing countries
• Complex, energy-intensive UK food system, heavily reliant on
just-in-time delivery, mainly by road
• Food prices on the rise after decades of decline – affordability of
fresh, healthy food an issue for increasing number of households
• Longstanding lack of connectivity between urban communities
and food production
UK food security policy
UK policy and research focused on:
• Global trade
• Supporting farmers
• Citizens as “consumers”
Foresight.The Future of Food and Farming (2011)
The role of cities in food security
• Little consideration of the role of cities in food policy
• Urban food planning a neglected but emerging area
• Leading Sustainable Food Cities: Toronto, Malmo, New York,
Manchester?
Manchester’s Food security
• Availability
– Extreme weather risks to supply, limited range
of ways to access fresh, healthy food
• Affordability
– Low income households spend higher % of
income on food
• Connectivity
– Health, environment and economy linkages,
urban/rural connectivity, urban production.
Green Infrastructure

What is Green Infrastructure?
Green infrastructure is a term used to refer to the living network of green spaces,
water and other environmental features in both urban and rural areas. It is often
used in an urban context to cover benefits provided by trees, parks, gardens, road verges,
allotments, cemeteries, woodlands, rivers and wetlands.
Green infrastructure is also relevant in a rural context, where it might refer to the use of
farmland, woodland, wetlands or other natural features to provide services such as flood
protection, carbon storage or water purification. Green infrastructure maintains critical
ecological links between town and country.
Around the country local partnerships are seeking to use green infrastructure to drive
economic growth and regeneration and improve public health, wellbeing and
quality of life. It can also support biodiversity and the functioning of natural
systems such as rivers and flood plains and help reduce the negative impacts of
climate change.

Likely Impacts of Climate Change on GI
• Biodiversity – wildfires, drought, alterations to season length, pressure on
species at edge of their range, invasives/pests and diseases
• Green space/public realm – longer growing seasons, stressed through
drought/flooding/heat, greater public use and therefore cost and benefits!
• Trees and Woodlands – pests, diseases, windthrow (“unseasonal” wet and
windy conditions), stress on some existing species with increased productivity
for others .e.g more beech less oak?
• Mosslands – drying out and wildfires, species loss and increased use causing
erosion, loss of habitat and release of stored carbon
How can we adapt to these impacts?
• Biodiversity – Enhance networks to enable species migration…..make landscapes
more permeable for species movement-corridors and stepping stones
• Green space – adjust species and alter management (e.g use drought resistant/deep
rooted species and then water if needed), may need more hard surfaces for extra use but
retain permeability
• Street trees – use/develop drought and pest resistant varieties….. planting
technique
to cope with both drought and excess water conditions!
• Woodlands – create linkages between woods, enlarge,
use continuous forestry cover
and adjust species mix if needed
• Mosslands – rewet where possible and retain seasonal water………reduce other
impacts (e.g scrub/invasives)
Green Infrastructure’s role in helping us adapt
• Managing high temperatures…..increasing green cover by 10%
could keep
surface temperatures to current level until 2100? Why……..2003 heat wave in Europe
claimed 52,000 lives.
• Managing surface water……..10% increase in green cover could reduce
runoff in
extreme events by 14%....SUDS. Retention of water supply e.g SCAMP
• Managing flooding………use GI for flood basin protection…..big SUDS
• Reducing soil erosion……use GI to preserve fertility and reducing siltation
• Managing visitor pressure……..meet demand for outdoor leisure closer to
home…. less travel with a more attractive and healthier environment
Also mitigation benefits…………………
GI in Greater Manchester
• GMGI Framework and action plan……and GI planning at different levels
• Red Rose and Pennine Edge Forest Partnerships……long established
• Physical delivery by wide range of organisations…….. Mossland
restoration, river valleys, urban green spaces, Newlands, Green Streets, green roofs,
• Strengthening the knowledge base………GRaBS, EcoCities, i-trees, GM Tree
Audit and potential valuation of GM’s GI/Ecosystem services?
• Securing investment………for both GI enhancement and
management
• Long term time horizon but action needed now……e.g need to plant street
trees now to cool our towns and cities in 20 years time!

Communities living Sustainably
• A five year programme aimed at changing behaviours
• Community-led
• Partnership-based (Community, Public, Private)
• Big Lottery Funded
• Groundwork Trust Mediated
• 270 Expressions of Interest
• 30 through to second round
• 10 will get up to £1million
Kersal Vale and Spike Island Climate Action Project
2008-10 4 key themes
• Flood Resistance
• Energy Efficiency
• Greening the Neighbourhood
• Education Programmes (waste and transport)
Partners : Chalk NDC, Salford Council, Salford University, Salix Homes,
Environment Agency, etc
Kersal Vale and Spike Island Climate Action Project
Very successful but :
“It is evident that the residents…face multiple deprivation….if this project
is to have success….it needs to understand these issues and work with
other local agencies….so that climate change becomes embedded into
service delivery”
• Levels of successful engagement relatively limited
• Active participation fell short of targets set
• Many residents not interested in climate change
• Only limited evidence that projects are affecting change in behaviour
Communities living Sustainably
• People resent being told what to do
• They don’t like being preached at
• They are pre-occupied with other complex issues
• They suspect a “do as I say, not as I do” attitude
Communities living Sustainably
The Broughton Trust Perspective : What works?
• Employing local people as champions and influencers
• Creating training opportunities linked to jobs
• Being there whatever and whenever
• Treating people with respect
• Starting from where residents are ie inside the community
Communities living Sustainably
The Broughton Trust Perspective : Evidence
• Lowest participation rate in adult learning in the city 2003
• Highest participation rate in adult learning in the city 2012
• Waiting lists in most subject areas, vocational and non-vocational
• Involving 1 in 40 of the East Salford’s population of around 40000
• Everything linked through simple pathways
• Barriers to Learning addressed (eg childcare)
• Pathways leading to employment and financial autonomy
Communities living Sustainably
What we want to do over five years :
• Employ Community Green Champions
• Fund community-based, community-led projects
• Set up a Co-op for food growing and amenity management
• Co-fund Partnership projects
• Organise a Valley Volunteering Programme
• Promote two Big Green Valley Festivals
