Emission
India’s Emission Pattern
The CO2 emission embodied in the consumption basket of top 10% of the population in urban India is one-sixth of the per capita emission generated in the US.
India’s CO2 emissions from fossil fuel use were less than five percent of the world total in 2007 (IEA 2009) but this is likely to increase with economic development & population rise.

INDIA: Growth Pressure
• Economy growing at ~8 % pa
• Population of 1.22 billion+
• Urban Housing deficit of 23 million
• 40 million rural Housing units deficit
• Increased migration to urban areas
• Climate refugees - Climate change induced post disaster reconstruction

Development or Preservation/ Conservation in INDIA
2. Benefits of Maintaining the existing through RETROFITTING
6. Efficiency in cities: a preliminary assessment of Potential ; D. Foy & J. Rogers, Living Cities Report, 2008
ECONOMIC BENEFITS•Saving money•Creating jobs and career opportunities•Boosts local economy•Takes less time than building a new structure, so normal function is suspended for a lesser period of time
SOCIAL BENEFITS•Improved health, quality of life and comfort•Improved productivity•Improved social welfare and poverty alleviation
ENVIRONMENTAL BENEFITS•Reduction in local/regional air pollution•Non- release of embodied energy already in the building which could have been released if the building was demolished to build a new one
3. Adaptation or Mitigation for India
Addressing multiple risks due to climate change is a serious public policy and adaptation management challenge for India.
On the face of climate change, adaptation and mitigation actions for cities in India are critically required where the urban population is likely to grow by around 500 million over the next 50 years.
The developed countries can afford to go for expensive adaptive programmes as they continue with their resource intensive industrialized economic activities.

3. Adaptation or Mitigation for IndiaIndia would preferably opt for a mix of two strategies which the local economy and people can sustainably afford.
Integrated policies like Coastal Zonal Management and mangrove forest regeneration, sustainable livelihoods through revival of marine ecosystems , construction of dykes and dams, solid waste and water resource management, disaster mitigation and management planning and implementation etc. are well-established mitigation strategies.
Urban planning for changed scenario, green technology, sustainable brackets, renewable solar energy generation to satisfy increasing demand, etc. are few potential adaptation strategies.

Inspirational Nature in INDIA
Possible Way-out
To deal the challenge to maintain human
wellbeing by provisioning for clean air and
healthy living is through conservation and
restoration of urban outdoor green spaces
Future Focus
Building or Surrounding Open Area
Beyond the buildings’ envelopes in urban area
can positively contributes to:
•physical and psychological health
•social cohesion
•climate change mitigation
•pollution abatement
•biodiversity conservation
•provisioning of the ecosystem goods and
service to urban inhabitants

CO-BENEFITS of
Retrofitted Urban Outdoor Spaces
in addition to Energy Efficiency are
• URBAN POPULATIONS’ COMFORT
• CONNECT WITH NATURE
Global Scenario & Standards for
Urban outdoor
Global scenario -EUGreen space coverage in cities of EU vary markedly: averaging 18.6 % range from 1.9 (Reggio di Calabria, Italy) to
46% (Ferrol, Spain)
Availability of urban green spaces per capita varied by two orders of magnitude, from 3-4 m2 per person in Cádiz, Fuenlabrada and Almeria (Spain) and Reggio di Calabria (Italy) to > 300 m2 in Liège (Belgium), Oulu (Finland) and Valenciennes (France)15. The scaling of green space coverage in European cities; Fuller, R. A. and K. J. Gaston; Biology Letters 5(3): 352-355, 2009
Global scenario -USA
Urban tree cover in the United States ranges
from 0.4% in Lancaster, California
to 55% in Baton Rouge, Louisiana; containing
approximately 3.8 billion trees with an average
tree canopy cover of 27 percent of urban areas.
16. Measuring and analyzing urban tree cover ; Nowak, D. J., R. A. Rowntree, E. G. McPherson, S. M. Sisinni, E. R. Kerkmann and J. C. Stevens; Landscape and Urban Planning 36(1): 49-57, 1996.
17. Carbon storage and sequestration by urban trees in the USA , Nowak, D. J. and Crane, D. E. ;Environmental Pollution 116: 381-389, 2002.
Global scenarioCuritiba, Brazil, with a population of 1.7 million, has urban green space 51.5m2/person from to 1 m2/person in 1970s.
Canberra, the national capital of Australia, at the beginning of the 1900s, was largely treeless. Extensive tree plantings began in 1911 and today, the urban forest on public lands contains 400,000 trees belonging to some 200 species in streets and parklands
Japan’s green space average is 6.1 - 8.5 m2/ person. The core of Metropolitan Area of Tokyo has green spaces of less than 20%, while surrounding area has 60-80% green spaces.
18. Is the Grass Greener? Learning from International Innovations in Urban Green Space Management; Carmona, M., C. De Magalhaes, R. Blum & J. Hopkins. CABE/ Bartlett School of Planning, London, 200319. Canberra’s urban forest: Evolution and planning for future landscapes; Banks, J.G. and Brack C.L.; Urban Forestry & Urban Greening 1: 151-160, 2003
Sustainable StandardsIn 20th century, experts in Germany, Japan and other countries proposed a standard of 40m² urban green space in high density zones & 140 m² suburb forest area per capita for reaching a balance between carbon dioxide and oxygen, to meet the ecological balance of human well-being.
Currently, developed countries have tended to adopt a general standard of green space of 20 m² park area per capita.
20. Analysis of problems in urban green space system planning in China; Wang, X.-J. ;Journal of Forestry Research 20(1): 79-82, 2009
Sustainable StandardsInternational minimum standard suggested by World Health Organization (WHO) and adopted by the publications of United Nations Food and Agriculture Organization (FAO) is a minimum availability of 9 m2 green open space per city dweller (Kuchelmeister 1998)
There is yet another yardstick, which refers to London but has relevance to any city. Abercrombie (1943) prepared a plan in 1943-1944 suggesting that 1.62 ha (four acres) open space per 1000 population was a reasonable figure to adopt for London.

Urban Outdoor GreenThree main components: 1. Patch (urban domestic gardens, public and private
parks & gardens, water bodies, urban forest patches)
2. Corridor (roadside avenues, walkways and urban greenways etc.), and
3. Network structure (linking the patches and the corridors).

Urban forest• the quality of life of city residents
• a place of social integration, recreation and relief from hectic life
• Economical, ecological and aesthetic benefits– Provide with an additional recreation and wildlife area.
– trees and green space provide significant advantages in terms of psychological and physical well-being.
– also provide free ecosystem services which are helpful in maintaining ecological integrity of expanding cities like carbon sequestration, watershed management, and biodiversity conservation.

Singapore
AIM: to promote biodiversity conservation, keeping in mind that as a densely populated country with no hinterland, one would have to adopt a pragmatic approach towards conservation and
develop unique solutions to challenges
TokyoAIM: to regenerate
its abundant greenery and
represents the basic concept and
directions of the green measures
New York City Eco-friendly measures
AIM: to mitigate the urban heat island effect with the
extensive usage of vegetation
Government Organisations:
•Building byelaws with development controls over open spaces
•Investing in experimental studies to mitigate Urban Heat Island Effects & other environmental impact
•Developing knowledge-base on appropriate construction Materials
Initiatives in India
Local Governments:•In Indore, an initiative to reuse natural channels for drainage not only brought changes in water logging scenario, also improved vulnerable slum dwellers’ condition.
•In Kolkata, East Kolkata waste land is an exemplary conservation attempt for natural sewage treatment
•Cities like Delhi, Pune, Hyderabad, Bangalore are implementing Rainwater harvesting system with increasing awareness about permeability issue/ surface transformation
Initiatives in India
•Corporate Houses:
• SAP Labs- Bangalore, while renovating, commissioned Ornithologists instead of Landscape Architects to get back the birds within the campuses
