NORTH LAKHIMPUR, July 8 - Erosion caused by the Subansiri river and the change of the course of the Ranganadi river due to the construction of a cofferdam here have affected hundreds of people in two separate areas.
Massive erosion by the Subansiri in Bhimpora under the Kadam Revenue Circle at Boginadi has affected a large area of agricultural land and an entire village this time around. The river has caused havoc on the eastern bank at Karkani with a return collision at Khalihamari on the western bank, eroding 10 to 20 metres of land every day. As a result, Hekerajan Mising Gaon is on the verge of extinction. Erosion protection works with the help of porcupines did not take place in the last dry season and as of now, the site where the concrete pillars were piled for have been swept away by the river. If this continues this monsoon, the commercial centre of Boginadi and the NH-15 may come under threat.
Meanwhile, a cofferdam built in the middle of the Ranganadi river to divert its stream from eroding a nearby tea estate has affected hundreds of villagers at Rangajaan Borbeel. A cofferdam constructed in 2013-14 by the State Water Resources Department to protect Goodricke India�s Dejoo Tea Estate from erosion, caused the river to change its course in 2015 towards the east, destroying the entire village of Borbeel. This has displaced 20 families. So far, no protection and rehabilitation measures have been taken up by the district administration and the departments concerned.
