The new BJP-led West Bengal government has prioritized handing over land to BSF for completing border fencing with Bangladesh, citing national security concerns, amidst ongoing issues of illegal migration, border incidents, and transnational crime.

Key points

Land Boundary Agreement (LBA): The 2015 implementation of LBA resolved historical enclaves and adverse possessions, demarcating the 4,096 km border, yet challenges like illegal migration persist.

Illegal Migration: Economic disparity and political instability in Bangladesh drive migration to India, fueling political movements like CAA and NRC, with significant demographic and resource pressure implications.

Border Incidents: Frequent BSF firings targeting trans-border criminal networks result in civilian casualties, raising humanitarian concerns and bilateral tensions.

Transnational Crime: The porous border facilitates smuggling of narcotics, cattle, fake currency, and human trafficking, with links to extremist groups posing security threats.

Security Concerns: Historical use of Bangladesh by NE insurgent groups and recent Rohingya influx compound security challenges, despite Dhaka's cooperation in dismantling militant infrastructure.

Teesta River Dispute: Unresolved water sharing exacerbates bilateral friction, with Bangladesh seeking equitable distribution for agriculture, while India views Dhaka's engagement with China warily.

[GS2-International Relations] The border issue tests India's 'Neighbourhood First' and 'Act East' policies, crucial for regional stability and economic groupings like BIMSTEC and BBIN.

Way Forward: Shift from 'border policing' to 'border governance' by enhancing bilateral cooperation, leveraging technology for surveillance, and addressing root causes like economic disparity to reduce illegal migration.

Key terms

Land Boundary Agreement (LBA)
The 1974 agreement between India and Bangladesh, operationalized in 2015 via the 100th Constitutional Amendment, resolved enclaves and adverse possessions, demarcating the border. It strengthened bilateral ties and regional stability but left issues like migration unresolved.
Border Security Force (BSF)
India's primary border guarding force, tasked with securing the 4,096 km India-Bangladesh border. Its role includes preventing illegal activities and managing border incidents, often involving complex humanitarian and security trade-offs.
Citizenship Amendment Act (CAA)
A 2019 law facilitating citizenship for persecuted minorities from neighboring countries, excluding Muslims. It addresses migration concerns but has sparked debates over demographic changes and secularism, linking directly to border security issues.
Teesta River Dispute
A bilateral conflict over water sharing of the Teesta River, critical for agriculture in Bangladesh. The lack of agreement fuels mistrust, with geopolitical implications due to China's involvement in Bangladesh's water projects.
