An effective surveillance system on the Indo-Bangladesh International border has foiled the terrorists and smugglers’ intrusion into India. A Comprehensive Integrated Border Management System (CIBMS) could be possible on the direction of Ministry of Home Affairs to protect the India-Bangladesh border.

Now in India's long border of 4096 km with Bangladesh, of which 135 km runs along the Barak valley's twin border distracts Cachar and Karimganj, there is a heavy deployment of the BSF. The National Building Construction Corporation (NBCC) and Central Public Works Department (CPWD) have fenced Assam, Meghalaya, Mizoram and Tripura on the Indo -Bangladesh border with barbed wire and handed over to BSF in Dec 2018.

Of 135 km international border in Barak valley, 65 km runs along riverine border of river Barrak which gets bifurcated at Hari Nagar border outpost ( BOP) into two Kushiyara and Surma rivers to enter Bangladesh. The riverine border posts, according to M L Garg DIG, Silchar HQ, have been fenced with night surveillance capabilities and armed with sophisticated weapons.

According to him, the BSF has been given additional task of assistance to The National Register of Citizens (NRC) centres in three districts, Hela Kandi, Cachar and Karimganj since Nov, 2017.

The Land Boundary Agreement was (LBA) signed on June 6, 2015 between India and Bangladesh.

This LBA helped to create Smart Border fencing model in 3 km stretch from Champabari to Lathi Tila area in Karimganj district . "The term, the Smart Fencing, refers to anti-cut, anti climb and anti rust designed to prevent intruders from entering Indian borders” told J.P. Maithani, Commandant BSF. Connectivity remains the bedrock of a more effective transportation infrastructure for India's Act East policy and bringing the Northeastern States into the mainstream of the Indian economy.

There is an Integrated Check Post at Sutarkandi for trade for border trade with Bangladesh. Trade starts from to 6 pm. It is cleared by custom departments and secured by BSF. Interestingly, in spite of mixed population there has been no communal violence since 1947 in the twin border districts. According to reports, a number of attempts were made to disturb these districts by anti social and anti national elements, but the people remained calm.
