Directions for Future Health Cities

E170 Fall 2017 final lecture (JMH,KMM,CCC)

• Ready to Roll:

• 1. Provide micronutrients to all consumers

• 2. Combat environmental racism for babies of color to live & thrive

• 3. Change Diets to protect human health and the health of the planet

• Too Big to Fail:

• 4. Finish the Environmental Sanitation challenge so “Clean Cities DO Grow”

• 5. Averting the next zoonotic disease pandemic

• 6. Implement best practices for urban health

• 7. Urban Design for families and communities: housing, immigration and the Sanctuary City

Theme 1.Agro-Industrial Partnership to eliminate micronutrient deficiencies everywhere

• Investing in fortified staples widely consumed by the poor;

• Investing in plant breeding research that will enrich staple crops, initially rice for Asia.

• Food industry’s products will strengthen developing world as a global trading partner;

• least cost-effective and sustainable solution .

The Agro-Industrial Partnership

HARVEST PLUS (2004 -- >)-- Target Countries and Crops

More than four million farming households reached by HarvestPlus by end of 2016. Crops released are high-

yielding with climate smart traits.

Functional Outcomes• Efficacy trials with provitamin A, iron, and zinc biofortified

crops have also shown improved functional outcomes:• Improved cognitive function (iron)• Better work performance (iron)• Better sight adaptation to darkness (provitamin A)• Reduced morbidity (zinc)

To Reach Urban Consumers, Growing Interest in

OFSP Processed Products

1) Increased interest in diversified products from OFSP, esp. for urban consumers

2) Food processing can improve bioavailability by disrupting plant tissues, etc.

3) OFSP puree (boiled and mashed) more economically viable than OFSP flour

4) Challenge it to get products highly commercialized

Bread in Mozambique

Power Biscuits in Rwanda

Theme 2. Eliminate Survival Gap for Babies of Color • USA annual : 23,000 infants die under 1 yr

• Black infants twice as likely to die as whites

• Milwaukee, Wisconsin hot spot for dying black babies (100/yr)

• 3x white rate

• Health Commissioner: “If 100 people died from TB, people would say we have a public heath emergency”

• Wisconsin Black unemployment 20%, highest in US

• Inner neighborhoods Milwaukee: 62% incarceration black men

• High school suspension rate black students (34%) highest in nation

• Lifecourse Initiative focuses on jobs for men, responsible fatherhood, “safe-baby sanctuaries in black churches, community gardens and community health teaching and out-reach (mom-to-mom)

Dana Meadows: Advice on analyzing and improving systems

Expand the boundary of caring.

Living successfully in a world of complex systems means expanding not only time horizons and thought horizons; above all it means expanding the horizons of caring. There are moral reasons for doing that, of course. And if moral arguments are not sufficient, then systems thinking provides the practical reasons to back up the moral ones. . . .

As with everything else about systems, most people already know about the interconnections that make moral and practical rules turn out to be the same rules. They just have to bring themselves to believe that which they know.

DALY SAVED < $25:

• Iron/folate fortification: $22/DALY*

• Salt iodization

• Daily (and probably weekly) oral iron for pregnant women

• EPI Plus (Child Immunization + Vitamin A)

• School Health (esp.iron/deworming)

• Health, Nutrition and Family Planning Information

• Breastfeeding promotion

Inequality and Health Disparity

• Poor neighborhoods can kill people

• Black women in Chicago: death rates from breast cancer 68% higher than whites; social isolation, stress hormones, poor access to screening and therapy blamed

• Might apply to raised rates of inner-city diabetes, stroke & CVD

• A Harlem male and a poor Asian farmer have same life expectancy

• Despite the NHS, the poor live a decade less than the well-off in the UK

• But country folk live 2 years longer, shrink wealth gap

• Work-related injuries are under-reported (U.S. OSHA ) by 2/3rds, occupational medical care sub-standard

• Developing countries often reduce their health budgets by the amount that donors provide

SDG #5: A Continued focus on women • Limited success of MDGs

• SDG #5: Achieve gender equality and empower all women and girls

• Some specifics:

• Recognize and value unpaid care and domestic by providing services and infrastructure

• Promote shared domestic responsibilities

• Equal opportunities for participation & leadership

• Equal rights to economic resources property ownership and natural resources

• SDG # 6: Pay special attention to the needs of women and girls and those in vulnerable situations

Impacts on Women and In Utero Environment

• Mothers with Type 2 Diabetes have an increased risk of:

• High Blood Pressure and preeclampsia

• Higher risk of miscarriage or still birth

• Risks to child:

• Organ malformation

• Overly large babies (nerve damage)

• Higher risk: childhood obesity & diabetes

Early Childhood is Critical for Motor, Mental, and Language Development

Intergenerational Impacts of Maternal Welfare(1)

• Disease and malnutrition: In utero environment compromised

• Early interactions between mother and child are critical to a child’s future: When a mother is exhausted, depressed, or anxious, the quality and quantity of mother-child interaction declines

• 2012 Study: Window of opportunity: 0 to 4 years

Neglect results in decreased brain size. Enlarged ventricles are associated with stunted neural development and atrophy.

Intergenerational Impacts of Maternal Welfare (2)• 2015 study confirms that poor sanitation is

associated with adverse pregnancy outcomes (APOs)

• APOs: low birth weight, prematurity, death

• India has the highest number of premature births

• 667 women in India studied: 60% no access to toilets; 40% with a household toile but infrequent use

• Estimated 7x greater of APOs with no latrine use

• But need both access and behavior change

Jane Jacobs: “Impossible to create a community without networks”• July 1995 Chicago heat wave killed 739 mostly elderly, mostly African-American (e.g. Englewood)• BUT Auburn Gresham NBHD one of lowest death rates in the city • Highest death rates? Healthy old folks living alone• “wellness checks, neighbor-to-neighbor house checks, referrals to

emergency services. Aging and sick were not left alone.” Betty Swanson, resident

• Survival rate of seniors related to depth of their social networks• Same in Paris Jl-Aug 2003: 15 K died because children on holiday, isolated

from families• Bigger networks function better because there’s always a default person

outside the family ready to respond

The Strength of Weak Ties

• Boston Job market: close friend only 17%, casual contacts 83%

• Pullman Porters (20K blacks) – weak link to connected clients (+++)

• Darwin: altruists will out-compete others

• Internal trust breeds economic success (Germany Sweden, Norway)

• Max Planck Institute: most people are ‘conditional altruists’, BUT

• 5% egoists will halve altruistic actions

• “Positive Deviance: (M.Zeitlin): (i) Viet farmers healthy babies (greens and shrimp) (ii) smoker among non-smokers (iii) non-immunized baby among immunized (iv) Thai social taboo re: water pot

• Changes in behavior motivate attitude change

• (+++) Neighbor hoods: best school performance -- > best health, lowest crime and teen pregnanc y rate

• Impact spreads to adjacent neighborhoods ”3 degrees of influence”

Theme 3.

Reversing Global Obesity Crisis

Obesity Jumps Globally since 1990

OBESITY EPIDEMIC

• 700 Mn including 106 Mn children• More obese adults than underweight• NO NATION HAS REDUCED ITS OBESITY RATE IN 35 YEARS• “The diet is killing us”• an epidemic of diabetes and heart disease• Food industry: unprecedented power in LDCs: pushing out subsistence

crops• MNCs: Incentives to grow sugar, corn, soybeans for packaged foods (up

25%) and meat• Fast Food cons’n 2011 – up 30% global 21% USA • THAT’s IT!!

REVOLUTION IN DIETS

• A. Land Use and Environmental Protection

• Grains and meat: disappearing biodiversity

• Land grabs and virtual water capture

• Shifting role of animals from grazers to fast food

• Habitat destruction directly caused but largely ignored

• B. Food, Health and Sustainability

• Global reach of food production and disease

• Antibiotic resistance and zoonotic emerging disease/pandemic?

• WHO: meat class 1 carcinogen

• Impacts on lifespan from overconsumption

• “One Health” for Ecosystem Protection

Livestock Emissions – Global

Farming forests and grasslands could reduce wildlife species by a third

• Could farmed animals be the most significant driver of climate change?

• If the whole world adopted the OECD appetite for meat, we’d need 75% more agricultural land than the world possesses (Vaclav Smil)

• Chatham House: the 2oC limit Paris accepted cannot be met w/o reducing meat eating

• And “the market is failing”

• Switch livestock industry subsidies to plant-based alternatives?

• Apply a carbon tax on meat?

Animals Produced for Annual Consumption

Current• T: 65 Bn

• Chickens 60 Bn.

• Cows 300 Mn*

• Pigs 1.4 Bn

• Ducks & turkeys 3.5 Bn

• Sheep & goats 1 Bn.

• That’s 9 animals per person per year on the planet! Who knew?

• * T: stock 400 Mn (1900) – 1.5 Bn

2015 - 2050

• Consumption doubled last 50 yrs

• Expected to double again (projected demand incl 3-4 Bn new consumers)?

• Unsustainable?? YES

Global Footprint (FAO)

Emissions (CO2-e)

• Methane 2.8 Bn T

• Manure 700 MnT

• C stores lost “

• Crops (feed) 2.6 GT

• Transp crops/meat 100 MnT

Efficiency (100 g cooked meat)

• Cow 450 g protein• Pig 110 g• Chicken 75 g

FOOTPRINT (per kg meat)• Cattle 16 Kg CO2• Sheep 13• Pig 5• Chicken 4.4

WHO: Meat Considered a Class 1 Carcinogen

• Red meats (beef, pork, veal, lamb) and processed meats bacon, sausage, hot dogs) in the same category of cancer risk as tobacco smoking, asbestos and ionizing radiation

• Risk jumps the more you eat, e.g. 1.8 oz meat daily -- > 18% higher risk colorectal cancer

• See Lancet article posted on Canvas

• This would force a recasting of the previous analysis (completed 2002) to reflect much higher cancer and heart disease deaths and much higher economic costs from exploding meat consumption

Trade, Junk Food and Nutrition Injustice

•Globalization is a double-edged sword

Burdens of Lack of Clean Water: Increased Soda Consumption and Diabetes? (1)

1971: “I'd like to teach the world to singIn perfect harmony; I'd like to buy the world a CokeAnd keep it company; That’s the real thing.”

Burdens of Lack of Clean Water: Diabetes? (1)

Double or triple digit percent increase of soda consumption in developing countries since 2009

“[A]ccess to clean drinking water is limited, so soda becomes a viable alternative . . . . People will say, 'We don't have anything else to drink.‘”

Dr. Lee (Director of the Global Obesity Prevention Ctr; Johns Hopkins University.)

Burdens of Lack of Clean Water: Diabetes? (2)

Mexico: Did necessity become cultural? • Mexicans consume the most soda

• 2000-2015: huge gains in rural access to clean water (74% to 92%)

• Children fed soda:~ 10% zero to 6 months; at age 2, ~80%

• One of the highest rates of childhood obesity

• Culture vs. Necessity vs. Marketing: • Mom’s like chubby kids; shows they are

well taken care of vs.

• Lack of clean water vs.

• Heavy marketing

Ad: Even Mexico’s indigenous people’s need Coke

Trade: Poor Countries Import Obesity-- > The Mexican Case after NAFTA• NAFTA abolished trade barriers for investment, IPRs, government

procurement

• No domestic content required for foreign firms

• “Nutrition transition” in Mexico exploded through free trade

• Obesity (adults) now 32%> USA; 25% school-age kids, 33% Mexican teens, 40% kids in Mexico City; fattest in Latin America. Why???

Mexico (2)

•1991-- > US exports meat, corn, soy 2-6X higher; sugary drinks up 40%, fruits and veg down 30%, processed chicken up 50%

•Mexico 3rd largest recipient of US FDI in processed food and beverage industries

•Mexico now resembles US industrialized food system: fat people starved of good nutrition

Mexico (3)

•Actions: implement WHO WHA resolution “ to address the potential challenges that trade agreements may have on health.”

•Require HIA for proposed agriculture trade policies•US Congress study nutritional outcomes of Ag

export expansion in LDCs•Strengthen protection for public health, safety and

environment in food sector

Brazil Goes Obese

Brazil Goes Obese (2): 2007-2017

• 58% overweight• 20% obese• 300,000 new Type-II Diabetes cases/yr• Food & Beverage industry 10% GDP, employs 1.6 Mn• 2006: ANVISA (= Brazil FDA) proposed new anti- packaged foods’

regulations and supported WHO exclusive BF to 6 mons policy• BR Assn Food Industries (w Nestle etc) paid $160 Mn to Br Congress and

the Presidential candidates• after election ANVISA replaced w Cargill VEEP, regulations went away• Called “censorship”, “violation of free speech”• 11 law suits pending to block ANY new Govt from fighting food industry

Brazil Goes Obese (3)

• 2010: Br Court ruled ANVISA has no authority to regulate food industry

• ANVISA reg to prevent food giants from sponsoring sports and music concerts REVERSED

• 2012: Coca-Cola sponsors “Lose Weight Brazil” campaign

• Big hit in Rio, Sao Paolo and Brasilia

• Street violence keeps kids inside: TV and snacks!!

• 2015: Brazil catching up !!

• % obese kids: Brazil 9.5% ( tripled since 1980)

• USA 12.5%

Food Industry Quotes

• Ahmet Bozer (CEO Coca-Cola): “ Half f the world’s population hasn’t had a Coke in the last 30 days. There’s 600 Mn teenagers who haven’t had a Coke in the last week, So the opportunity for that is huge.”

• Mike Gibney (Nestle nutrition adviser): “We’re not going to get rid of all the factories and go back to growing all grain. It’s nonsense. It’s not going to work.”

• Nestle employs 21K door-to-door food vendors in Brazil, 9K products . Corporate Goals? “create shared values/ create micro-entrepreneurs/send a positive message about nutrition”

• Favorite seller? “Chandelle Pacoca peanut-flavored pudding 3.5 oz = 20 grams sugar = WHO recommended daily limit

• Food industry mergers (Tyson-Hillshire Brads etc) are eliminating the competition.

• Barry Popkin (UNC): “emblematic of an insidious new era – companies ae not leavng an inch of country aside”

Nestle junk food packages paid by ‘Bolsa Familia’ (Brazil Government income supplement)

Three Degrees of Influence: ObesityObesity Network Impact on Health Risk

• Framingham Heart Study: life expectancy lowered 7-8 years

• Obesity tripled to one-third American adults (half century)

• ~ $200 Bn/yr spent on obesity-related health issues

• Friendship is key “risk”

• My “friend”: my risk up 57%

• 2 friends in a network: risk up 171%

• Target people at center of social clusters: surround high-risk people with good behavior (non-obese, non-smokers, immunized kids)

Nutrition Interventions for Obesity and Overweight

• School-based training for improving diet and activity levels (e.g. Singapore)

• Extension workers to teach traditional cooking methods (e.g. South Korea)

• Dietary Guidelines for nutritional well-being (e.g. China)

• Nutritious meal planning for public schools

• Mass Media (e.g. campaign to reduce overweight in Brazil)

• Food Labeling

• Agricultural research to decrease the fat content of livestock products

• Focus on preschoolers before it’s too late to correct –many US public schools are training 4-5 yr olds for good diet and exercise

• Yo, Diabetic Nation! At a YMCA near You ( 128 total)

U.S. toddler obesity down 43%

• Large study of low-income kids by CDC

• Among 2-5 year olds (age when obesity settles, hard to reverse (5X more likely obese adults)

• 8% obese (2012), from 12% (2004). Why?

• Maybes: consuming fewer Kcals from sugary beverages; federal WIC program reduced fruit juices, cheese, eggs, increased fruit&veggies

• Michelle Obama channels the Thai Princess??

Sugar Tax Needed (U.K. Plan)

• Reduce added sugars by 40% (2020)• No targeted marketing processed sugary

drinks & food to kids

• Ban junk food sports sponsorships

• Reduce saturated fat 15% in processed foods (2020)

• Limit availability and portion size I markets

• Implement a sugar tax to shift diet preferences

• Create an independent agency to ensure accountability for good nutrition

• Poor sanitation led to stunted adults

• Shifts in the structure of diet

• Food subsidies a factor: meat, fats, sugar

• shifts in physical activity

• obesity and diabetes trends; prevention weak

• morbidity and mortality shifts

“METABOLIC PROGRAMMING”

FROM EARLY LIFE

A range of country studies (U.K., Sweden, US, India, among others) have reported that LBW infants in later life had increased hypertension, coronary heart disease, adult-onset diabetes, and auto-immune thyroid disease.More than 30 studies show a relationship between lower height and increased hypertension.Overall, the evidence of adverse long-term effects of maternal, fetal, and infant malnutrition is very strong.

Theme 4. Finishing the Environmnental Sanitation Challenge

• Science at its best

• Broadened to encompass the whole environment

• Recovery and recycle economic goods for equitable development

‘Sanitation Rated the Greatest Medical Advance in 150 Years’• British Medical Journal survey 11,000 readers

• Followed by antibiotics & anesthesia

• Chadwick and Snow were on to something

• BMJ’s survey of diarrhea diseases in LDCs: death and damage reduced by one-fifth directly and more if reversed child stunting included

• BUT….

• The individual commode only gets us so far

• Indian kids from rich families are still stunted and cognitively compromised

• The challenge NOW to cleaning up the refuse entirely

• Then “ Clean Chicken WILL Grow”!

What is the current situation worldwide?

Solid waste management examples from:

■ Jakarta

■ New York

■ Lagos

■ Tokyo

■ Sao Paulo

■ Amsterdam

.

A short video on urban waste

.

JAKARTA

.

Jakarta: Nowhere to go but upDue to the lack of formal recycling, waste pickers are key to reduce

the amount of waste

Jakarta: Nowhere to go but up

-The country has grown significantly in the last years

-Many of this waste is directed to Bantar Gebang (one of the largest landfills

worldwide)

-Lack of proper work conditions for the waste pickers

-Yakarta is one of the countries that more plastic dispose into the ocean

-Waste pickers have an important role within the waste chain.

https://www.washingtonpost.com/graphics/2017/world/global-waste/?utm_term=.229326d5ded1


.

New York

New York: A bold goal in the Big Apple: ‘Zero Waste’

-One of the top world´s mega-cities on waste production

-High population density creates big challenges

-Food waste is a significant problem in the NY (and US)

-Recycling is higher than in other US cities but still limited

-A “Zero Waste initiative” has been signed “under Mayor Bill de Blasio”

-” The city’s goal is to eliminate the transfer of garbage to out-of-state landfills by

2030.”



JAKARTA.

Lagos: works to slow a rising tide

’


Lagos: works to slow a rising tide

-One of the fastest growing cities in the world (21 mill pple)

-They receive illegal waste from Europe and US

-Waste pickers are also vital to the city

-Landfills are out of capacity

-Very little organic waste on the trash

-Waste is used as a filling compound to reclaim land and build more houses



.

Tokyo

Tokyo: Short on space, Tokyo gets proactive’

-Tokyo metropolitan area is one of the most populous in the world (36 mill

pple)

-Advanced technologies for recycling

-There are 48 incinerators

-They capture the heat to supply energy for different purposes

-There are also 12 landfills around the city



JAKARTA.

Sao Paulo: relying on people power


Sao Paulo: relying on people power’

-It has around 21 million people

-More waste has been generated as the level of income of some groups have

increased.

-Garbage picker/scavenger” is an official profession

-The type of recyclers are divided in plastic, can and paper

-They are organized in cooperatives



Sao Paulo – An Example

JAKARTA.

Amsterdam: looks to burn less, recycle more


Amsterdam: looks to burn less, recycle more

-It has 900.000 people

-Most of the waste is incinerated at the moment

-New facilities have been developed to recycle more plastic

-The Netherlands is currently importing waste from UK

-Paper and glass are very well recycled in the city additional efforts will be

required for food.



SOLUTIONS

-All cities and their residents are different therefore multiple solutions working synergically will be required to solve the Solid waste management problem

-Close loops of waste management should be incentivized

-Appropriate air and water pollution controls should be enforced to guarantee a long term sustainability performance

-Waste picker play an important role in the developing world, to keep many of the cities that they serve running. Adequate safety and other working conditions will be required to make it sustainable.



Theme 5. New Bird Flu Strain Spreads Oct 17

Fifth “Wave” H7N9 infections China 9/16 -- >

• 1600 infected positives, 40% died

• Viral lineages: Yangtze and Pearl after rivers were influenza has spread

• Earlier versions

• H5N1 avian flu (2005): 860 infected, half died, 16 countries, still circulates Egypt and Indonesia

• H1N1 (2009) “swine flu” Mexico, infected factory farms all over US

Animal Production and Waste Out of Control

Rob Wallace : “Big Farm, Big Flu”

• HxNx: global dispersion

• Mom&pop chicken coops and wild, migrating fowl are not the pandemic risk

• New strains appear to be adapted to industrial poultry production near urban centers

• Molecular adjustment: evolving new attributes fit for infecting poultry

• New H5Nx : influenzas adapted to intensively raised poultry i.e.

Healthy Cities

WHO, 2016

• As defined by WHO:

“A healthy city is one that is continually creating and improving those physical and social environments and expanding those community resources which enable people to mutually support each other in performing all the functions of life and developing to their maximum potential.”

• Over 1000 cities designated worldwide

But the type of home you are in matters…

And the connections within the city….

Healthy Cities are hyper-connected

• More recently, focus on “social, innovative and smart cities” (Boulos et al, 2015)

– Barcelona – Save $75 Million on water, lighting and parking management due to smart city designs – but saved countless more on health costs

• Technology isn’t an panacea, though – need impact assessments

Healthy Cities are hyper-connected

• Also need a redesign if possible:

• Waste bins, internet, environmental sensors – all to increase productivity and efficiency of services.

• Superblock: residents have priority, cars limited to 6 mph!

Healthy Cities are … Super Cities?

China Healthy Cities –

One option

Via Verde Condo Complex (South Bronx)

• model green affordable urban housing (opened 2012)

• Garden-covered roofs: orchard, F&V gardens

• Energy-efficient (30%upgrade), pro-health design

• Health center, pharmacy, gym, community room, kitchen, children’s playroom, community rooms, amphitheater

• Rents and co-op apartments priced on affordability to clients

• Healthy materials

• 80% materials’ recycled

• Access to schools, shopping, sports fields, public transit

Via VerdeSouth Bronx, NY

Access to green space, 151 affordable housing rentals and nutritional resources

(Rosen, 2017).

Theme 7. Cities can be protective

• Must provide the following:

• Opportunities (Economic, Social)

• Access (To food, water, transport)

• Resources (Food, water, energy, internet?)

• Support (All the above, emotional, physical?)

Thanks to Michael Kilmurray for this!

Metabolic realignment for survival

• We must realign the metabolism of cities to adapt to shifting populations, services and needs.

• Increased displacement, with perturbations? E.g. war, climate change.

• Case Mongolia (2016): “Reaching Every District” strategy delivering an integrated package of health services, given shifting social context of populations. (Lhamsuren et al, 2012)

• Focus on the social determinants of healthand social values of populations.

• Case US (2017): Sanctuary cities provide hope and stability.

120

New Home, New Values, New Governance & Design

• Historically, GDP/$ metrics of human value→ De facto city design of segregated, under-served, sick neighborhoods

• Emerging evidence: Equity/Quality of life correlated with Productivity

• Solution: Design urban spaces & governmental institutions to effectuate “people-centered” prosperity

• Substantive equity follows procedural equity

• Risks of status quo: social unrest, health, economic productivity/cycle of poverty, human dignity

To be sustainable, cities must be a permeable membrane

From the New York Times (2010)

Cities as a membrane

• Membrane for:

• Water (flooding, freshwater, sewage)

• Migration (people, ideas, energy)

• Energy (fuels, foods, and factories)

• Etc. (Iaconesi and Persico, 2012)

• Cities can also self-regulate (like a cell) (Johnson, 2002)

Cities as a membrane

• Luckily: human interaction and production scales super-linearly (above linear).

• This is a multiplicative increase, and is a function of the network dynamics.

• Consider for disease prevention and other viral phenomena (Schlapfer et al, 2014).

• For example, behavior change and urban development.

• The communication networks can be a tool for positive and negative change.

The case of China: migration• Over 10% of China’s population

migrates for labor.

• In search of better jobs and opportunity.

• 57% of these people obtain a job in the city from a friend or relative.

• 45% are between 16 and 25, two-thirds male (due to traditional division of labor).

• Hukou (household registration, 户口) does not account for this.

• Thus, a “floating population” (Wu et al, 2013; CFR, 2009).

• A pressure in the membrane –but also an opportunity

Tianjin Eco-City, China

• How do we adapt to such an influx?

• Build new infrastructure –increases jobs

• China has produced a number of eco-cities, sparking global interest.

• However, eco-city projects such as the Tianjin Eco-city did not address the movement of worker populations throughout the city.

• Sao Paulo – map of the impoverished core

Cooperative Housing



From Eco-City to Sanctuary City

• Sanctuary areas produced a greater number of stable immigrants (Ceubula, 2015)

• Associated with lower cost of living, and greater humidity (?)

• Also associated with better well-being estimates.

• Have to address OARS!

• Social networks are more secure

• This can support ongoing efforts such as Tianjin Eco-city.

• Summary: The path for China’s workers through sanctuary from hukou?

China’s Approach to

Healthy Cities

Summary:

• Sanctuary areas can provide a path to lower cost of living, better well-being, greater exercise and green-space access (Ceubula, 2015).

• This can support Healthy/Smart cities.

• While protecting migrants and those at risk • Climate change

• Conflict

• Summary: The path of China’s megacity workers from sanctuary to hukou as an example for cities globally.
