Open Spaces
to Make Cities
Healthy

2. Green Spaces in Urban Context
Cities more than just buildings
• Most liveable /famous cities known for open areas
• As cities grow-- green space becomes more
important/valuable.
• Paris Climate Change Agreement-making cities sustainable
and livable-
• --Promoting larger green cover–
• planting more trees
• -- taking green cover from 24-33% by 2030
• - creating additional carbon sink of 2.5- 3 b tonnes
• AMRUT-- Atal Mission for Rejuvenation and Urban
Transformation – Government of India--
• Increase amenity value of cities –
• --by developing greenery
• ---well maintained open spaces -- with special provision for
chlidren, senior citizens /Divyang friendly components
Challenges– Land/resources /development/ maintenance
3. Green Spaces in Urban Context
• Various frameworks call for promoting Green spaces in our cities.
• New Urban Agenda calls for;
• -- an increase in safe, inclusive, accessible, green and quality public
spaces.

4. Green Spaces in Urban Context
In land use planning -urban open space
defined as areas under:
-- “Parks", “
--Green spaces“.
--Play fields
-- Recreational areas
-- Natural landscape
which is-- Open to public
but Does not include
