Urban resilience to flood risks in Chennai
Preliminary Research FindingsShazade Jameson14th August 2013
Outline
• Background to Research• Theory• Methods• Preliminary Findings– Causes of flooding– Institutional Social Capital– Knowledge Management– Rights issues
• Tentative Conclusions: Financial & Infrastructural Violence
Why Chennai?
• Chance2Sustain – WP3: Environmental Risk
Assessment– WP4: [Participatory] Knowledge
Management in Urban Governance
• Special relationship to water…• Acute water scarcity /
inequalities• Rainfall > national average =>
Flooding
… either too much or not enough
Environmental Risk
By 2050: developing world will be 67% urban India’s current population 1.2 billion (UN 2012)
Chennai = Low Elevation Coastal Zone (LECZ)Greater risk from climate change
Not everybody experiences risks the same.
Risk = hazard x vulnerability
Socioeconomic Vulnerability
Adaptive Capacity
1. Institutional Social Capital Cooperation? Conflict? Sites of
overlap? Networks? Power relations?
How do people work together?
2. [Spatial] Knowledge ManagementActors and their networksDiscoursesProductsConsequences
Critical Urban Theory
Infrastructure shapes spaceSpace shapes social relations…. & social relations shape space …. & infrastructure.
= co-construction.
What are the consequences for socioeconomic inequalities?
In short…
How do long term flood knowledge management systems build or hinder institutional adaptive capacity to flooding, and what are the effects for the city’s current resilience to floods?
Qualitative Methodology

Causes of Flooding
Gupta & Nair 2011
Long term flood management requires attention to all these aspects.
In Chennai’s urban governance, “flood management” does not exist as such.
Causes of flooding: Direct
1. Encroachments
- “Legal”- “Illegal”
2. Water bodies reclaimed
3. Loss of traditional rainwater harvesting system (Eris)
Watch the Oggium Madugu connect Pallikaranai to the back waters, though obstructed by Kannagai Nagar Flats
ExNoRa
Till Sep 2002, the Madugu is still connected to the Muthukadu back waters
ExNoRa
Aug 2004 the back water is fragmented and dry
ExNoRa
April 2009, the marsh disappears and land mass appears
ExNoRa
Cause of flooding: Indirect
Causes of Flooding: IndirectArchaic British land use codes inapplicable
High population pressure = high land value
Lack of holistic recognition of water
Improper solid waste management - Level
- Location
Institutional Social Capital
Very little. Ignoring bigger picture makes it difficult!
lack of participatory process
Why? • Different priorities• Different knowledge domains
Funding (JNNURM) prioritised as separate departments
Sites of cooperation:- Informal personal connections. Requires personal investment.- Technology
High-tech mapping
Aerial Laser Terrain Mapping
Highly accurate, 30cm elevationdetermines flood risk
Defense issue Only “user agencies”
Hazard-centric viewpoint“In a vision from above, a city is just a layout of streets, but what happens there is
hidden.” - Fernandez
Storm Water Drains
Lack of records
= Minimal centralised knowledge management
Feasibility of plans checked by inspection
Lack of monitoring of construction
Different urban networks in conflict
Prevents potential drinking of floodwater
Performativity of records
Cause of flooding depends on which department you work with
Fear of blame Records kept minimal
Reinforces dominance of engineering approach
Socioeconomic & Environmental variables tend to be ignored, only dealt with during flood relief
Reinforces individual informal social capital
Success from the top down
New ideas pushed through mostly by top-down support
Procedures can be performative
E.g. Conservation Authority of Pallikaranai Marshland = CAPML
Multi-departmental societySupport from Chief MinisterNew funding mechanismAfter 15 years campaigning by CSOs
…. Requires political will
Flood Management as a Human Right
[“illegal”] “encroachments” universally blamed for floods
Resettlement = political issue
Further segregation of engineering approachArgument of city modernisation & beautification IT Corridor = floodplain = compounding vulnerabilitiesParticipatory methods not taken up for lack of skills & timeAlso, vested interests in land reclamation
Tentative Conclusions
Flood management as a human, ecological and economic right unaddressed by complex entanglement of priorities
Lack of holistic & participatory flood management despite relative awareness
Resilience requires redundancy & flexibility, transparency and openness for innovation at all levels.
Implementing agencies suffocated by restrictive funding and narrow mindsets.
Financial and infrastructural violence ignoring lived experience
Thank you!
