opportunities for transformation - from a disrupted 'anti-eco-city-region' towards a post-industrial eco-region
Zone (c)
Chennai - I.T. corridor
Coastal-to-hinterland landscape with hi-tech industrial and entertainment/scenic corridors, interspersed with fishing villages, salt pans and small-scale farming
Hi-tech hubs and gated communities and villas interspersed with fishing villages, farms and waterbodies with two major roads running through
Upscale gated communities, beach homes, amusement parks juxtaposed with small coastal fishing villages transitioning into a post-industrial economy — IT hubs, electronics and information services alongside traditional livelihoods - fishing, salt pan work and recent hobby cultures - eg: horticulture gardens: Mid-to-high population growth, speculative real estate development, hostels for IT workers, slum resettlement colonies and social housing schemes, fishing hamlets
Middle and upper-middle class lifestyles interspersed with large-scale slum resettlement complexes : with complex ecologies - backwater lagoons, marshes and wetlands; loss of casuarina groves and wetlands. Fragmented enclaves, modern aspirations,
The IT Corridor was developed as a high-investment corridor, “future of the city”, ECR transitions from weekend getaway to attracting high-end residential real estate; Lots of global traffic owing to IT and electronics investments, expat communities; multiple ecosystems at risk from surge in populations in the past 2 decades
Zone (c)
Chennai - I.T. corridor
High-risk coastal infrastructure, floods, fragmented land/waterscape
Extreme rainfall events, drought, sea level rise
degraded water bodies leading to floods.waterlogging, gradual sea level rise and storm surge-risk
degraded ecologies, polluted water bodies and channels, coastal risks — impacts on indigenous livelihoods
Zone (c)
Chennai - I.T. corridor
Rapid urbanisation leading to fragmented landscapes coastal infrastructure risk and loss of livelihoods
Low-lying brackish water and freshwater bodies, dry tropical scrub, mixed land-use
Speculative developments leading to encroached water bodies and wetlands
fragmented local governance, complex
Zone (c)
Chennai - I.T. corridor
fragmented local governance, complex
Challenges constitute regulating and provision of basic services like sewage disposal and clean drinking water as it contains zones which are amongst the last few added to Chennai municipal boundaries; created pockets of large slum resettlement housing amidst gated communities and hostel dwellings
Rise of new-age farmers, restaurants with locally-grown food, small-scale horticulture and hobby gardening centres creating niche clienteles and simultaneously new imaginations around environmental awareness and conservation - mostly individuals or small citizen groups
large tracts of land on lease to individuals which have been rented out to tenants, farmers, salt pans etc. SEZ’s have separate arrangements with firms that have set up offices within these planned areas
potential for new-age farmers and environmentally-conscious to create pockets of resilience if they work together; small fishing hamlets and farming communities possess varying levels of social capital
Zone (c)
Chennai - I.T. corridor
potential new forms of eco-urban form & design, in new forms of community
rapid-growth corridor/IT/electronics/service economy
impacts of climate change felt across the landscape, further breakdown of social cohesion, isolated communities
synergies of alternative eco-socio-economic models - tourism, nature trails, small agricultural cooperatives, revival of local ecologies
regional/landcape planning and monitoring bodies, local resilience enhanced through ecosystems stewardship and smalls-scale economies
