Smart cities in one indicator

  1. 1. Smart Cities in Mathematical models for city analysis: one indicator!!! an approach applied to Smart Cities + 14 Valentino Moretto valentino.moretto@dhitech.it Puglia Smart Lab
  2. 2. Puglia Smart Lab PSLab is a newborn LL, a space of innovation in which citizens, Government and enterprises collaborate together to co-create services derived from concrete needs in our territory. PSLab is one of the first outcomes of Puglia@Service, a research project funded by the Italian Ministry of University and Research. The aim of P@S is providing a 15-young professionists group with multidisciplinary skills necessary for smart territory strategic development. Puglia@Service project is supervised by Dhitech Scarl, a High Tech District (established since 2005 in Apulia). PSLab has officially joined ENoLL, European Network of Living Labs, as an adherent member, since August 2013 at "The 7th wave of ENoLL members”.
  3. 3. CITIES EVOLUTION •In the USA urbanization was minimal until 200 years ago; today it’s above 82% •China will be building 300 new cities in 20 years •One million people a week will be moving in cities until 2050 18 La Habana 7 Houston 11 Marseille 5 Santo Domingo 12 Athene 3 Naples 10 Igmir 4 Sapporo 8 Istanbul 6 Bayrut 13 Shangai 17 Ningbo 16 Fuzhou 19 Port au Prince 15 Tel Aviv 14 Benghazi 2 Baranquilla 9 Jakarta 20 Algeri 1 Alexandria Source: www.zonu.com/detail-en/2009-09-18-7103/Growth-in-Megacities-1950-2015.html Source: www.befan.it/entro-il-2050-136-citta-a-rischio-scomparsa-ce-anche-napoli/

A JUNGLE OF INDICATORS Use of non- car transport Green transport promotion Green technology Green Action Plan PM10 Emission GDP/GHG Emission NOx Emission Deficit/GDP CO2 Emission Density GDP ROI- Return on Investment Water Consumption Waste Water Treatment Energy Intensity Nitrogen Dioxide Total Fertility Rate Total Population Congestion Reduction Policies Public Participation in green policy Green Transport Urban Growth Rate ROS- Return on Sales ROE- Return on Equity Source: www.internazionale.it/la-formula-che-spiega-le-citta/
  5. 5. IN BIOLOGY… “…bigger species require less energy per Kg when compared to smaller species. As an example, an elephant needs 1000 times more energy than a guinea-pig despite being 10000 times bigger…” …AND, INSTEAD, WHAT HAPPENS IN CITIES? http://www.internazionale.it/la-formula-che-spiega-le-citta/
  6. 6. WEST - BETTENCOURT THEORY Every living being gets slower as its size increases. This is called sublinear behaviour. However cities are different: when their size increases, every social aspect speeds up. There is no equivalent model in nature! Source: intersci.ss.uci.edu/wiki/index.php/Realistic_modeling_of_complex_interactive_systems
  7. 7. 15% RULE – CITY SUPERLINEAR SCALING There are two different trends due to city size increase •Superlinear - raising social interactions means more innovation and wealth, but higher crime rates as well (β = 1.15). •Sublinear - less investment per capita infrastructure required such as streets, cables, sewage, etc. (β = 0.85). Source: /intersci.ss.uci.edu/wiki/index.php/Realistic_modeling_of_complex_interactive_systems
  8. 8. WEST-BETTENCOUR MID STEPS Non linear behaviour in urban MIXING networks transport POPULATION Decentralized networks for people INCREMENTAL connectivity NETWORK GROWTH City Behaviours The bigger the city, the more BOUNDED mental/physical effort but HUMAN EFFORT social interactions as well Socio-economic outputs are SOCIO-ECONOMIC proportional to local social OUTPUT interactions
  9. 9. G INDICATOR G is the output that represents the entire set of urban aspects as well as the condition for existence and enhancement of cities. G = Y (Social interaction outcome) – W (dissipation) Gmin: City does not exist Gmax : City collapses G*: City output maximization Source: www.theatlanticcities.com/neighborhoods/2013/06/scientific-proof-cities-are-nothing-else-nature/5977/
  10. 10. G* INDICATOR It is necessary to shift G* forward, in order to improve city users’ life conditions, in spite of city dimension increasing. This would result in better socio-economic outcomes and more social interactions. How? Citizenship proactive participation Innovative urban planning Balancement between density, mobility and social connectivity Source: G. West, "Is a quantitative predictive,science of cities conceiveable? What can we learn from physics & biology? Santa Fe Institute, Said Business School, Oxford University. February,2012
  11. 11. OUR GOAL An innovative analytic assessment way to exploit cities’ full potential A tool to provide support to Government for a better understanding of cities A new methodology for long term strategical planning of cities
  12. 12. …SO, WHAT’S OUR REAL GOAL? …Involve you, stimulate your partecipation to Puglia Smart Lab, experiment together this new methodology. Next year, in Smart City Exhibition 2014, we would like to present outstanding. Do you wanna team up with us?
