Basic Structure

The Land Boundary Agreement (LBA) 2015 between India and Bangladesh resolved decades-old border disputes through the exchange of 162 enclaves and settlement of adverse possessions. The agreement required India's 100th Constitutional Amendment to modify Article 1 and Schedule I, reflecting territorial changes.

India transferred 111 enclaves (17,158 acres) to Bangladesh, while receiving 51 enclaves (7,110 acres). Adverse possessions totaling 2,777 acres went to Bangladesh, while India received 2,267 acres. Approximately 51,549 people were affected, with over 98% choosing to remain and acquire new citizenship.

The agreement came into force on July 31, 2015, eliminating administrative complexities and improving bilateral relations. Key provisions included joint demarcation of undemarcated segments, comprehensive rehabilitation packages, and establishment of new border infrastructure.

The LBA represents a successful model of peaceful border dispute resolution through diplomatic negotiations, demonstrating constitutional flexibility and humanitarian approach to affected populations.

It has facilitated enhanced cooperation in trade, connectivity, and security between the two countries.
