urbanisation and its effect on people's health

Urbanisation and its effects on people’s health

Dr. Rizwan S A, M.D.,

Any city however small, is in fact divided into two, one the city of the poor, the other of the rich. These are at war with one another. - Plato

Definitions - 1

What is an urban area?

• According to Census of IndiaA. All statutory places with a municipality, corporation, cantonment

board or notified town area committee, etc.

B. A place satisfying the following three criteria simultaneously:

i. a minimum population of 5,000;

ii. at least 75 per cent of male working population engaged in non-agricultural pursuits; and

iii. a density of population of at least 400 per sq. km. (1,000 per sq. mile).

Definitions - 2

What is an urban slum?

i. All specified areas in a town or city notified as ‘Slum’ by State/Local Government and UT Administration under any Act including a ‘Slum Act’

ii. All areas recognized as ‘Slum’ by State/Local Government and UT Administration, Housing and Slum Boards, which may have not been formally notified as slum under any act

iii. A compact area of at least 300 population or about 60-70 households of poorly built congested tenements, in unhygienic environment usually with inadequate infrastructure and lacking in proper sanitary and drinking water facilities

Definition - 3

• What is urbanization?– Urbanization refers to the change in size, density and heterogeneity of

cities

• What is urban health?– The health of a population that lives and works closely together,

usually in an incorporated area, such as a city or town, with a common water supply and with similar environmental conditions

– The status of health in urban populations– Urban Health means putting the needs of people and communities at

the heart of the urban planning process to ensure better access to urban services which improve human health for all

Urbanisation trends - 1

• Indian Scenario - 2011– Total Population

• 1028.6 Million– Urban Population

• 286 Million (27.8%)– Growth rate

• Rural – 17.9 %• Urban – 31.2 %

– Estimated Slum Population • 60 Million

• World Scenario - 2010– Total Population

• 6906.5 million– Urban Population

• 349.4 million (50.6%)– Growth rate

• Rural – 0.22 %• Urban – 1.91 %

Urbanization trends - 2

• Movement of people from rural to urban areas with population growth equating to urban migration

• A double edged sword• On one hand- Provides people with varied opportunities and

scope for economic development• On the other- Exposes community to new threats

• Unplanned urban growth is associated with• Environmental degradation • Population demands that go beyond the environmental

service capacity, such as drinking water, sanitation, and waste disposal and treatment

Double Burden of Diseases

• Overcrowding and related health issues• Rapid growth of urban centers has led to substandard housing

on marginal land and overcrowding • Outbreaks of diseases transmitted through respiratory and

faeco-oral route due to increased population density• It exacerbates health risks related to insufficient and poor

water supply and poor sanitation systems• Lack of privacy leading to depression, anxiety, stress etc

16

Double Burden of Diseases• Air pollution and its consequences• Due to increase in the numbers of motorized vehicles and

industries in the cities of the developing world• Problems of noise and air pollution• Air pollution can affect our health in many ways with both short-

term and long-term effects• Short-term air pollution can aggravate medical conditions like

asthma and emphysema• Long-term health effects can include chronic respiratory disease,

lung cancer, heart disease, and even damage to other vital organs

17

Double Burden of Diseases

• Water and sanitation problems• Due to increasing urbanization coupled with existing un-

sustainability factors and conventional urban water management

• Nealy 1.1 billion people worldwide who do not have access to clean drinking water and 2.6 billion people i.e. over 400 million people, lack even a simple improved latrine

• Can lead to increased episodes of diarrhea and economic burden

18

Double Burden of Diseases

• Upsurge of Non-communicable diseases• The rising trends of non-communicable diseases are a

consequence of the demographic and dietary transition• Decreases in activity combined with access to processed food

high in calories and low in nutrition have played a key role• Urbanization is an example of social change that has a

remarkable effect on diet in the developing world

19

Double Burden of Diseases

• Traditional staples are often more expensive in urban areas than in rural areas, whereas processed foods are less expensive

• This favors the consumption of new processed foods• This places the urban population at increased risk of NCDs• In India, chronic diseases are estimated to account for 53% of all

deaths and 44% of disability-adjusted life-years (DALYs) lost in 2005

20

CHALLENGES TO HEALTH SYSTEM

• Increased burden of diseases associated with overcrowding, poor sanitation and hygiene

• Diseases associated with air and water pollution

• Lifestyle and stress related diseases, accidents/violence, substance abuse

• Diseases of nutrition

• Various administrative units with little coordination.

• Districts and zones not clear• Lack of grass root level

structures like PRI’s

• Inequitable distribution of health facilities

• Multiple agencies/bodies providing health care

• Lack of Standardization and standard treatment protocols

• Lack of integrated HMIS and databases

• Large segment of urban poor

• In migration and floating populations

• Diverse social and cultural backgrounds

• Greater vulnerability of the migrating populations

SOLUTIONS FOR URBAN HEALTH DEVELOPMENT

Framework for improving health outcomes in urban areas

WHO initiatives on urban health

• Theme of World Health Day – 2010– Thousand cities, thousand lives

• WHO recommends the five calls to action to build a healthy and safe urban environment:

1. Promote urban planning for healthy behaviours and safety2. Improve urban living conditions3. Ensure participatory urban governance4. Build inclusive cities that are accessible and age-friendly5. Make urban areas resilient to emergencies and disasters

Health system in Urban India - 1

No well organised services in urban areas

• Urban family welfare centers (UFWC)– Provide outreach services - primary health care, maternal & child

health, and distribution of contraceptives• Urban health posts (UHPs)• Postpartum centres (PPCs)

– Provide outreach family welfare services to various slum populations

• Medical colleges– Provide tertiary health care services as well as primary health care

services to urban areas

Health system in Urban India - 2

• Urban ICDS projects– Set up to promote health & development of women &

children through integrated packages of services for urban poor

• Urban basic services scheme & urban development projects– Provide basic maternal &child health services

• Urban malaria schemes (UMS)– Under UMS, surveillance staff & vector control teams have

been provided to control vector borne disease• Urban RCH projects

– Each project covered about 100,000 urban slum population

Health system in Urban India - 3

• Other facilities run by– Central/ state govt– Municipalties/ Municipal corporation– NGOs– Private sectors– ESI dispensaries

Health system in Urban India - 4

National Urban Health Mission • In order to effectively address the health concerns of the

poor population, the Health Ministry proposes to launch National Urban Health Mission (NUHM).

• The NUHM would have high focus on– Urban Poor Population living in listed and unlisted slums– All other vulnerable population such as homeless, rag-pickers,

street children, rickshaw pullers, construction and brick and lime kiln workers, sex workers, any other temporary migrants

– Public health thrust on sanitation, clean drinking water, vector control etc.

– Strengthening public health capacity of urban local bodies

Urban development schemes in India - 1

• Jawaharlal Nehru National Urban Renewal Mission– To encourage reforms and fast track planned development of

identified cities• Provision of Urban Amenities in Rural Areas (PURA)

– To simulate urban amenities in rural areas to discourage migration to urban area

• National Urban Sanitation Policy– Ministry of Housing and Poverty Alleviation is administering a

Centrally Sponsored Scheme for Integrated Low Cost Sanitation

Urban development schemes in India - 2

• National Urban Housing & Habitat Policy– To promote sustainable development of habitat to ensure

equitable supply of land shelter and services at affordable prices to all sections of the society, through strong partnerships between public private and cooperative sectors

• Interest Subsidy Scheme for Housing the Urban Poor– To provide interest subsidy on housing urban poor to make the

housing affordable and within the repaying capacity of EWS/LIG

• North Eastern Region Urban Development Programme– Projects undertaken: Water Supply, Solid Waste Management,

Capacity building, institutional development and investment programme management, Sewerage and sanitation projects

Urban development schemes in India - 3

• National Capital Region Plan– Provides suggestions and strategies to develop the

surrounding 108 urban and 7,528 rural settlements situated in the adjoining states of Haryana, Rajasthan and Uttar Pradesh by creating employment opportunities and strengthening infrastructure

• Tax Free Municipal Bonds– Funds raised from Tax Free Municipal Bonds are to be used only

for capital investments in urban infrastructure for providing one or more of the following:- Potable Water Supply, Sewerage or Sanitation, Drainage, Solid Waste Management, Roads, Bridges and Flyovers, Urban Transport

Urban development schemes in India - 4

• Swarna Jayanti Shahari Rozgar Yojana (SJSRY): – 3,76,855 micro enterprises have been set up and 3,93,913

urban poor have been imparted skill upgradation training

• Valmiki Ambedkar Awas Yojana (VAMBAY): – 3,69,499 slum families have been covered for providing

them shelter/dwelling units and 59,885 sanitation units have been sanctioned.

• Integrated Housing & Slum Development Programme

Role of other sectors - 1

• Urban planners– Use zoning and land use regulations to prevent exposure of city

dwellers to pollution emissions hazards from industrial activities, waste and chemicals, and well as transport

– Develop/adopt building practices that protect health among building users regarding indoor air environment, safety, noise, water, sanitation and waste management, among several other health determinants in urban settings

– Build compact cities, where dwellers have easy access to green areas, public transport, cycle paths and health, education and other fundamental social services.

– Incorporate Health Impact Assessment (HIA) into the consideration of alternative planning choices and policies.

Role of other sectors - 2

• Local governments– Show leadership by providing role models and by setting an

example– Champion walking, cycling, active lifestyles and community

designs that support these activities.– Foster collaboration within local government through

forums for city departments (such as transport, health, public safety, parks and recreation and education) to discuss the development of an integrated urban health strategy

– Encourage public health and urban planners to work closely together

Role of other sectors - 3

• Civil society– Ensure that people are fully engaged in shaping the

policies and programmes that affect their lives– Include residents of informal settlements in formal

processes by setting up groups, associations and federations• Organizations of the urban poor should come together to

– Identify social & economic conditions they are facing– Find practical solutions to these problems– Struggle against marginalization & – Ensure access to goods and services

Role of other sectors - 4

• Researchers– Generate and systematize knowledge to address

many existing information gaps, including:• potential advantages of urbanization and urban growth• Inequities of health disaggregated by intra-urban area• Effectiveness of proactive approaches to deal with

health inequity in cities &• Importance of involving all citizens in the decisions that

affect their habitat and their health.

Take Home Messages - 1

• Urbanization due to migration– Is a reality– Has reached to considerable proportions – Leading to increased growth of slums– Will increase further to greater proportions in the foreseeable future

• Slums lack infrastructure in basic amenities like safe drinking water, sanitation, housing etc

• At increased risk of both communicable and non communicable diseases

40

• Urban health is– Traditionally neglected in policy making– Need of the hour considering the facts and figure available

regarding the population at risk

• Failure of NRHM to take urban health into account and pending launch of NUHM

• Policy influence needs to be done to sensitize the policy makers towards urban health issues
