2. Green Spaces in Urban Context
• Cities more than just buildings
• Most “liveable” /famous cities – known for
their open areas---.
• As cities grow-- green space becomes
more important/valuable.
• Paris Climate Change Agreement mandates-
for making cities sustainable and livable- --
Promoting larger green cover by,
• -- planting more trees
• -- creating larger carbon sink
• -- taking green cover from 24-33% by 2030
• - to create additional carbon sink of 2.5- 3
billion tonnes
• challenge-– space, resources /

3. Green Spaces in Urban Context
In land use planning -urban open space ----
areas for:
-- "parks", “
--green spaces“.
--playing fields
-- recreational areas
-- natural landscape which is--
• Open to public access
• Does not include
• -- areas outside city boundaries / open
space in countryside,
. Streets, piazzas, urban squares

5. Status of Open Spaces

6. Status of Trees- Man Ratio

7. Objectives
and
Benefits of
open spaces

9. Benefits of green space in cities
• WHO--physical inactivity --a major public health
risk.
• Studies found -- people using open spaces --
three times more physically active
• Users - prefer nearby, attractive/larger parks/
open spaces
• Improving access / creating Network of parks /
open spaces results in--
-- increased physical activity
-- improved mental health
--better general health,
---reduced stress levels,
---- reduced depression
--reduced healthcare costs.
--- environmental benefits.
-- providing healthy habitats for humans/
wildlife / plants in densely built places
--- preserves ecosystems amid growing cities.

10. Benefits- Open Spaces
Open space provides 3 kinds of benefits to citizens
• Recreation, Ecology, Aesthetic value
1 Recreational
• -- active recreation --organized sports / individual
exercise
• -- passive recreation-- being in open space.
• -- Reprieve from urban environment.
2 Ecological
• -- Conserving nature-
• - Creating ecological awareness.
• -- promoting biodiversity
• -- providing home to natural species --
3 Aesthetic Value
--People enjoy viewing nature..
-- make neighbourhoods attractive
-- create positive attitudes
-- increases walking

11. Advantages of Green Spaces
• Open space in urban environments
provides many advantages:

22. ECO-CITY TIANJIN- Master plan..
1. Land-use Planning – compact city , mixed land uses ,Transit-Oriented Development (TOD) .
2. Transport Planning -Green transport .-- majority trips via public/ non-motorised modes of
transport --bicycles and walking
3. Green and Blue Network Planning---
--City planned with extensive green (vegetation) and blue (water) networks
-- to provide quality living /working environment.
--Green network -- green lung at the core and eco-corridors emanating from the lung to
the other parts of city.
-- Water bodies linked to enhance ecology /provide attractive environment , recreation
-- A wastewater pond rehabilitated /transformed into a clean/beautiful lake.

Rao, Sukhna Choe

29. Chandigarh Landscaping
• landscape plan based on the principles of:
– Catering to vehicular and pedestrian
movement along V2 & V3.
• All old existing trees retained to give a
feeling of ancientness.
• Trees of both exotic/indigenous variety
planted.
• Tree plantation in the form of
squares/circles…. in singles and clusters .
• Concept of city forest introduced --by
planting trees in large numbers in clusters to
create beautiful effect.
• Landscaping within vertical green belts
made to provide unobstructed view of
Shivalik hills.
• Trees act as buffer against dust/noise and as
wind breakers.

30. CHANDIGARH PLAN --- ALBERT MAYER
• Designed for a
Population of
500,000.
• Based on a system
of low density
• neighborhoods
defined by a grid of
slightly curved
roads.
• Two natural valleys
run across the site
proposed to be
developed as park
strips.

51. Context of
Trees

52. Need for Tree Preservation
• Agricultural / urban expansion --at
expense of native ecosystems /
forests/ woodlands/ croplands/
grasslands.
• Cumulative effects --produced serious
global environmental/ social problems
• -- loss of biodiversity
• -- extreme poverty of people living in
the more vulnerable areas
• -Need to leverage
• Climate Change Convention,
• Convention on Biological Diversity,
• The Desertification Convention (Ruis,
2001)

53. GREENING CITY
•Mechanism of appropriate landscaping at city/building levels
make cities/ bldgs energy efficient.
•Vegetation shade--
-Lowers daytime temperatures
-- controls humidity.
--Reduces heat emission during night
•Manages water
--during rains --lot of free water absorbed
-- during dry periods--- water is evaporated
•Clean air, reduce noise, lower temperature
--filter air up to 80% of pollutants
-- Reduce noise level up to 12 db
-50-100 m thick vegetation cover
Reduces air temperature up to 3.50 c
•Greening cities through
--Strategic plantation
--Massive plantation
--landscaping
--Developing city forests.
---An tree offers a cooling effect -- 5 air-conditioners,
Generates fresh air equivalent to 7 cylinders
- Improve indoor air quality
-- Energy savings : 20-30

54. Importance of Trees

• Trees provide food
• Trees heal
• Trees mark the seasons
• Trees create economic
opportunities
• Trees bring diverse groups of people
together
• Trees provide a canopy and habitat for
wildlife

• Trees increase property values

56. Importance of Trees
•Tree source energy from renewable
source--sun.
•Waste’ generated by Tree ---as fallen leaves
is recycled by--invertebrates, fungi and
bacteria in the soil-- to provide nutrients to
the tree and other organisms.

57. Chandigarh Tree Preservation Order

chopping of trees allowed
without permission

58. Context/
Strategies for
open spaces

59. Strategies for Open Spaces
• Open spaces- provided as integral part of city planning
• Made Essential part of urban infrastructure and not an add-on / -
• Open spaces to be valued - need to develop basis of valuation
• Hierarchy of open spaces to be defined
• Space Norms for all levels must be defined
• Open areas distributed all over city.
• Concentration of open spaces to be avoided
• All derelict areas/ low lying areas/areas of natural/manmade
beauty be earmarked as open spaces/parks/recreation
• Encroachment from open areas to be removed and developed
• Involving people in planning, designing, development and
maintenance of open spaces
• Corporate sector /institutions --actively involved in developing
/maintenance of open spaces
• City to prepare inventory of open spaces
• Spaces to be safeguarded from encroachment.
• Organising competition for best gardens at residential/
institutional level etc
• Organising dedicated festivals- like Rose Festival to promote
open spaces

60. Strategies for Open Spaces
• Private colonies --to provide minimum 10% area under
open spaces – planned,developed and maintained by them
• Group housing to provide min. 20% area under open
space
• City to provide open spaces @ 9 sqm/per capita
• Careful positioning /Planning of open spaces
• Open spaces abutting /backing on houses – to avoid
misuse/encroachment
• Open spaces planned to face majority of houses for
optimization and preventing encroachment
• Promoting planned development --best option to create
open spaces
• Industries mandated to create green belts
• All existing trees/ natural areas to be preserved
• Tree Preservation law to be enacted
• Master Plans/ Development Plans to provide detailed
plans for open spaces
• Industrial /Residential area to be segregated with a green
belt

61. Strategies for Open Spaces
• Water bodies planned /developed as green/recreational areas
• Concept of City forests promoted to develop green cover
• Native plants to be used for plantation
• Xeri-scape used for landscaping to minimize water requirement.
• Land belts coming under High Tension lines—reserved, planned,
developed as open spaces with shorter variety of trees to avoid
mishap.
• Parking /hard areas planned /planted with trees to minimize
heat island effect
• Involving institutions and campuses having large area for tree
plantation/landscaping
• Making environment/ ecology integral part of education/study
curricula
• Creating awareness about role /importance of green spaces at
individual/community level
