Building a health creating society
In 1948 all the people and organisations involved in health care came together around the common goal of health care for allNow we need everyone and everybody that affects health to come together in a common goal to build a health creating society

How does nature benefit health?(a) Less stressed,
(b) More exercise,
(c) More positive social interactions and (d) Better quality environment for health promotion (i.e. has lower levels of air pollution)

• Disconnection from nature causes chronic stress
• We eat badly and exercise less• More visceral fat, inflammation • Result: an epidemic of chronic
disease e.g. diabetes , heart disease
• Being healthy is about friends, family, nature and feeling good about ourselves.
• Nature reduces stress connects people, increases activity and is generally more healthy

Overview
• The common challenge on Non-communicable disease
• Responding to the challenge• The evidence: Horticulture and health • Looking ahead
How Horticulture and PH can work together
The current and future challenges for health and social care in the UK
•Addressing the health and wellbeing gap •Healthy life expectancies gap•Increasing burden of preventable disease•Persistent health inequalities
•Addressing the care and quality gap•Persistent variations in healthcare
•Addressing the financial gap•Opportunity costs of not having a prevention focus
The need for a system wide approach of communities supported by their NHS, local authorities and voluntary sectors. 43 How Horticulture and PH can work together

To improve & protect the nation’s health & wellbeing and improve the health of the poorest, fastestOutcome 1) Increased healthy life expectancy – taking into account health quality as well as length of lifeOutcome 2) Reduced differences in life expectancy between communities (through greater improvements in more disadvantaged communities)

Key Commissioning Priorities
51 How Horticulture and PH can work together
• Health • Acute pressures (A&E, GP apt)• Recurrent or prolonged treatment costs
• Public Health• Preventable mortality & morbidity• Obesity – predominantly childhood• Life course issues – childhood, old age
• Social Care• Adult social care costs for residential/domiciliary care
• Employers• Productivity & sickness absence
TIMESCALE OF RETURN ON INVESTMENT

Evidence
Growing and strengthening evidence base for cost-effective interventions delivered by horticulture
Particularly strong for:• Mental health / Dementia• Physical activity • Wellbeing• Air quality
Growing evidence base in relation to physical health, with some good evidence around initiatives such as green gyms
How Horticulture and PH can work together
Cultural commissioning: a public health perspective
Working together
53 How Horticulture and PH can work together
Historically commissioning of horticulture schemes for health has been very small scale primarily non-recurrent pilots & grants.
Moving to sustainable provision requires cultural shifts for both commissioners and providers.
Recognition that horticulture is a wide spectrum encompassing big business and a large industrial workforce
Recognition that providers need to deliver the outcomes commissioners are commissioning for and in a measurable way.
Lots of learning from cultural and physical activity sectors who are on the same journey.
Looking ahead• Ageing population with growing
burdens of multiple health challenges
• Working age is increasing and millennials will often have portfolio careers
• Public sector is refocusing and prioritising on outcome based commissioning
• Inclusive universalism vs targeted minority approaches

Gardening Its Value in Terms of
Human Health and Well-being ?
Dr Ross Cameron & Dr Alistair [email protected]
Context!
• New Species • Homo westernmanicus
• Physiology of a Hunter Gatherer
• But, lifestyle of a brick
Background to Gardens
• Western Society = 90% live in urban areas.• UK - 87% households have access to a garden (Gibbons et al., 2011). • Gardens = 22-36% of the total urban area (Mathieu et al., 2007).
• In UK = 1/3 to ½ of urban green space (Loram et al., 2007).
• But decreasing area dedicated to gardens - infill & new houses having smaller gardens. (Smith, 2010).
• Under-represented in the Green Infrastructure equation (Cameron et al., 2012).
Reported & Derived Benefits(e.g. Cameron, 2014)
Green Space
• Pain relief• Blood pressure• Heart rate• Less frequent illness• Improved cognitive function• Thermal comfort
Gardens• Reduced mortality • Higher bone density, less
osteoporosis• Cholesterol levels • Reduces onset of dementia
Regular gardening / gardening like activities thought to help offset • Heart disease• Ischemic stroke• Type 2 diabetes• Hypertension• Anxiety• Depression• Certain types of cancer
Gardens as Therapeutic Landscapes
• Landscapes with natural features, provide greatest restoration from stress (Ivarsson and Hagerhall, 2008) .
• Even within these – restoration promoted by presence of flowers and water – stronger correlation than presence of animals, trees, hills, natural aromas or sounds (Ogunseitan, 2005).
• Design of garden may be important in offsetting stress associated with work, commuting, family life etc., but this warrants further investigation.
Gardens & Gardening • Under-researched in Nature-Health agenda• Rel. little info on private gardens
– (more on community gardens / allotments & hort therapy)
• H&WB benefits potentially large• Heterogeneous landscapes though - in typology, but
also uses and attitudes
Gardens & Gardening • Associated with: (Clayton, 2007; Blair et al., 1991; Dallosso et al., 1988).
– Providing a form of ‘retreat’ – Interacts with nature– Place to be creative– Play and recreation– Socialise (family and friends)– Utilitarian – grow food– Physical exercise (depending on task)– Identity – self–expression
– Also though • Pressure – chores – social expectations - keep up with the Jones’
• Extent of benefits may relate to individual’s attitude to gardening.
1. Immediate Access
• Little organisation required.• Frequent activity & repetition
– fits into short periods of down-time in busy working lives.
• Children - easy access to nature and food education.
• Food gardening used to encourage physical activity in children and encourage healthy diet (Castro et al., 2013)
• Community gardeners had significantly lower BMIs for same gender syblings (−1.88 female) (−1.33 male).
• Also lower probability for overweight or obese than otherwise similar neighbours (Zick et al., 2013).
Calories burned h-1
• General gardening 239• Raking 262• Trimming shrubs 278• Weeding 278• Digging 318, • Pushing powered mower 358 (De Simone 2016)
• Compare Moderate Cycling 470-650
3. Gardens as Restorative Landscapes
• Self-absorbing – Soft fascination. Attention Restoration Theory – ‘being mentally away from the stressors’
• Repeat activity – fascination led
• Keen gardeners rarely need much motivation to garden!
• Ecological, rather than anthropogenic, view of the world.
Restorative Landscapes• Older – adults.
– Gardening more than a casual leisure pursuit - critical to their physical and psychological wellbeing. (Scott et al., 2014) .
• Allotment gardening – Single session showed significant improvement in self-esteem (P<0.05) and mood (P<0.001) (Wood et al., 2015).
• For patients suffering severe stress / mod-mild depression - significant reductions in primary healthcare visits and inpatient psychiatric care when placed on a garden orientated rehabilitation programme. (Währborg et al., 2014)
4. Creativity – Self Expression• Gardeners - control over the design / management .• Positive psychological aspects - self-esteem, feeling of
achievement and fulfilment of talent.• Form of art therapy.
