Nettoor (also spelled as Nettur aka Tirunettur) is a village located on Panangad Island at the outskirts of Kochi in Kerala, India. It is part of Maradu Panchayath. The backwaters have a unique ecosystem – freshwater from the rivers meets the seawater from the Arabian Sea. In certain areas, such as the Vembanad Kayal, where a barrage has been built near Kumarakom, salt water from the sea is prevented from entering the deep inside, keeping the fresh water intact. Such fresh water is extensively used for irrigation purposes
Kerala backwaters have been used for centuries by the local people for transportation, fishing and agriculture. It has supported the efforts of the local people to earn a livelihood. In more recent times, agricultural efforts have been strengthened with reclamation of some backwater lands for rice growing, particularly in the Kuttanad area. Boat making has been a traditional craft, so has been the coir industry.
