4. _1 WATER AND URBANITy
_ WATER conditions the URBANITy, in the way it is supplied, circulates
and it is eliminated from the urban environment (Swyngedouw, 2004)
_ BALANCE between WATER and URBANITy is determined by:
_ the capacity of urban planning procedures and hydrological models’ performance to
integrate factors from climate change, demographical variations, new technological
discoveries and urban growth
(Zevenbergen, Cashman, Evelpidou, 2010)
_ the link between human water-related activities and
the other of water-dependent ecosystems
(Carmon and Shamir 2010)

( e.g. typhoon and tsunami in japan french Atlantic Coast)
_ REgIONS WITH A MEDIUM RISK Of NATURAL DISASTERS
( e.g. water scarcity and water salinisation in Barcelona )

12. _3 WATER SENSITIvE CITy
_ Developed in Australia, in an extreme climate with a high rate of water related hazards
_ Balance between water and urbanity through a series of conceptual recommendations
_avoid and recover after water related hazards
_to adapt to climate change and urban growth
_express the community’s values and aspirations in relation with water
_ Brings closer water management and urban planning
habiter 30/ 04 / 2014 11 WATER SENSITIVE CITY // DS²BE

13. _ By improving STORM WATER MANAgEMENT, you increase urban liveability
(Wong Brown, 2009)
_ Previous practices:
_ North America Best Management in Practice,
_ UK Sustainable Urban Drainage
_ french speaking community as Alternative Measure to Surface run-off
_ Resource for human life and urbanity
B5LVNRIÀRRGLQJDVDQRSSRUWXQLW
_ At the ground level and not underground
_ Change in mentality and practice

14. _4 RESEARCH qUESTIONS AND OBjECTIvES
BUT....
SENSITIvE STORM WATER MANAgEMENT PRACTICES were applied just in isolated
cases, due to:
_ Concept elaborated for extreme climates / high rates of water related hazards
_ Different terminologies, similar directions - Lack of general recognition
_ Concept vs Effectiveness
habiter 30/ 04 / 2014 13 WATER SENSITIVE CITY // DS²BE

15. _ MAIN OBjECTIvE
To evaluate the capacity of ‘water sensitivity’ to bring new insights to storm water
management practices
through an ASSESSMENT TOOL
comprising indicators from:
WATER MANAgEMENT,
PERCEPTIONS Of WATER IN THE CITy,
WATER gOvERNANCE.
habiter 30/ 04 / 2014 14 WATER SENSITIVE CITY // DS²BE

16. _ ADDIACENT OBjECTIvES
to position the concept of WATER SENSITIvE CITy within the evolution of contemporary
models for the city.
WRGH¿QHSTORM WATER’S BENEfITS in the urban water cycle by combining systemic
(techincal concerns) and anthropological (urban perceptions)
to introduce different perspectives into the process of DECISION-MAKINg.
