The revival of Narayanapuram wetland is a fitting example that good things can come out of government’s willingness to associate with independent organisations for the betterment of the society.

Once home to over 400 water bodies, Chennai’s development story is similar to most metropolises across India. Urbanising at a hurried pace, the concrete city spilled over its waterways and wetlands, leaving behind a sorry tale of ecological destruction. The Narayanapuram wetland, part of the massive Pallikaranai marshland, which was recently taken up for restoration, shows that not all hope is lost; not yet, at least.

Desalination is considered a solution to increasing water shortage in the world. A few functional desalination plants in Tamil Nadu, however, show a different picture.

Population growth estimates suggest that India will be supporting over 1.5 billion inhabitants by 2050 if the present growth rate of 1.9 percent per year continues. From 710 billion cubic metres (BCM) in 2010, the demand for water is expected to surge ahead to 1180 BCM in 2050 as the Planning Commission has predicted a 2.5-time increase in domestic and industrial consumption.

Better green cover could be a way to reduce the extent of disaster a Vardah could bring. Here’s a lowdown on the trees that Chennai must have.

 

Literary works from the Sangam period dating back to the fourth century BC indicate the presence of a five-fold classification system of geography and related ecosystems. The five types include kurinji (mountainous region), mullai (forests), marudam (croplands), neithal (seashore) and palai (desert landscape). And, the coastal city of Chennai fits snugly in the neithal landscape.

While sundry development and infrastructure projects beautify the Chennai coastline, fishermen are left to fend for themselves.

Going by the statistics from the Central Marine Fisheries Research Institute, Tamil Nadu’s coastline is densely populated with 573 fishing villages along 13 coastal districts. The story is slightly different around the urban and peri-urban coastline, thanks to the ongoing gentrification of the coastline in most parts of urban India. Traditional fishing hamlets are slowly giving way to plush beachfront properties. Spaces frequented by fishers are often viewed as “eyesores” on pristine beach stretches.

After a brief interval, the north-east monsoon made its presence felt through the cyclonic storm Vardah, terrorising both coastal Tamil Nadu and Andhra Pradesh.

Chennai’s disastrous December run continues for the second year in a row. While the devastating flood of December 2015 remains etched in the city’s collective memory, cyclone Vardah was no less scary and did not lag behind in its severity.

Chennai’s topography, along with civic apathy, official lethargy and a complete disregard for its natural floodplains see the city reeling under severe waterlogging every year.

Chennai’s drainage system--both natural and man-made--is unparalleled. Three rivers flow through the city--the Kosasthalaiyar to the north, the Cooum cutting right through the centre and the Adyar to the south; around 16 major drains criss-cross the metro in addition to the mammoth Buckingham canal along the coast. Around 2000 km of micro drains flush stormwater out in addition to the Ennore creek and the Pallikaranai marsh. “What more does a city need?” remarks professor S. Janakarajan from the Madras Institute of Development Studies (MIDS).
