For a flood-free Chennai
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. Posted on 07 Dec, 2016 09:07 PM

Crop change for better yield?
Crop patterns in India are changing without consideration for local agro-climatic conditions. This puts a burden on environment, incurring huge long-term losses. Posted on 15 Nov, 2016 10:48 AM

The past few months saw Karnataka and Tamil Nadu bickering over the sharing of the Cauvery water.
