Researchers say these areas of Kerala (Pallipad, Karuvatta, Veeyapuram, Edathwa, Thakazhi, Kuttanad) are a dumping zone for rest of the area.
Pallipad was a traditional Panchayath with vast paddy fields and clean water sources, over the period of time these paddy fields were filled with concrete buildings, this not only spoiled the agriculture production but also affected the nature and environment.
