Sustainable development is development that meets the needs of the present without compromising the ability of future generaDons to meet their own needs.
What is “Sustainable development” ? Report “Our Common Future” (1987) of the World Commission on Environment and Development (General Assembly of the UN)
Two key concepts: • The concept of 'needs', in par?cular the essen?al needs of the world's poor, to which priority should be given.
• The idea of limita?ons imposed by the state of technology and social organiza?on on the environment's ability to meet present and future needs

Q2: What are the city sustainability indicators ?
Indicators are needed for: • Observa?on, • Analysis, Understanding • Planning, Control
“We can not control what we do not measure”
Indicator : some thing that indicates the state or level of something (Oxford Dictionary)
Indicators of sustainable development are crucial for: • Crea?ng a “concrete defini?on” of sustainability.
• Elabora?on of strategy with goals to be achieved and means to be mobilized.
• Tracking progress towards goal. • In case of a gap between goal and realiza?on, readjus?ng the strategy.
In 1995 the Commission on Sustainable Development of United Na?ons (CSD) proposed a set of indicators for SD
1995 : « Blue Book » :134 indicators for sustainable development
2001 : « Blue Book » Second Edi?on :134 indicators were reduced to 58
New set of indicators 14 themes :
In France : Grenelle de l’environnement 2009 : Grernelle 1 2010 : Grenelles 2
Grenelle 1 : 13 areas of SD
United Kingdom

3 QuesDons
Q2: What are the city sustainability indicators ?
• City structure and organisaDon • Local government & competency • Unsustainable expansion • Funding of the city sustainable development
3.1 City structure and organisa?on
The City : CiDzen & acDvity
The City : buildings (habitaDon, services and work)
The City : infrastructures
• Water (drinking and sewage) • Energy (gas, electricity, hea?ng) • Telecommunica?ons
Urban Networks: the vein of the city
• Buried (invisible, ...) • Mixed (old and new, some more than 150 years old) • Huge investment and opera?ng costs • high interdependency
Urban Networks in Jakarta were designed for one million In 2011, the city has more than 18 million
Networks may be undersized:
In some ciDes, water leakage could reach 40%
3.2 City organizaDon Local government & competency
The City: part of larger enDDes : Metropolis, Department, Region, State, Great region,…
CITY State
Local gouvernement in France
• Municipality : 36 700 (in 1884) • Department : 101 (in 1871) • Region : 22 (in 1982) 2015 : Reduc?on to 12
Local gouvernement In France
