Land Boundary Agreement 2015

Topic: India and her Neighbours · NCERT: Beyond NCERT

Meaning

The Land Boundary Agreement (LBA) 2015 is the final step of the India–Bangladesh land border deal. It began as the 1974 Indira-Mujib Agreement and was completed by a 2011 Protocol. In 2015, the Constitution (100th Amendment) Act, 2015 gave Parliament's approval. Under it, India and Bangladesh swapped 111 Indian enclaves (inside Bangladesh) for 51 Bangladeshi enclaves (inside India). They also settled adverse possessions and about 6.1 km of border that had never been marked [1][2].

It matters because it closed a border dispute that had lasted for decades, and did so peacefully. It also ended the stateless life of about 51,000 people on India's longest land border (4,096.7 km) [3].

Explanation

The problem it solved

• Enclave: a piece of one country that lies fully inside another country.
• People living there were cut off from their own government.

• They had no schools, no police and no proper ID papers.

• Adverse possession: land that legally belongs to one country but is held and farmed by people of the other country.

• Undemarcated border: a stretch of border that was never marked on the ground. About 6.1 km of it lay in three sectors.
• Why the border was messy in the first place:
• Rivers cross the border many times and shift their course after floods.
• Chars (sandy islands made of river silt) appear and wash away within a few years.
• Villages and farms sit right up to the border line, and some houses sit on the line itself.

How it was solved, step by step

• 1974: Indira Gandhi and Sheikh Mujibur Rahman signed the Indira-Mujib Land Boundary Agreement. It was never fully carried out.
• 2011: a Protocol (an add-on agreement) settled the details that were still open.
• 14–17 July 2011: a joint headcount found about 51,549 people in the enclaves. Of these, 37,334 lived in Indian enclaves and 14,215 in Bangladeshi enclaves [1].
• 2015: the Constitution (100th Amendment) Act, 2015 was passed.
• Why an amendment was needed: giving away Indian land changes India's territory.

• That change needs Parliament's approval through a constitutional amendment.

• 31 July 2015 (midnight): the enclaves were formally exchanged.

What was exchanged

	Number	Area
Indian enclaves inside Bangladesh (went to Bangladesh)	111	17,160.63 acres [1][2]
Bangladeshi enclaves inside India (came to India)	51	7,110.02 acres [1][2]

• Total enclaves swapped: 162.
• Enclaves: India gave away more enclave land than it got.
• Adverse possessions: India came out ahead. It received 2,777.038 acres and transferred 2,267.682 acres [1][2].
• Citizenship by choice: residents could stay where they lived and take that country's citizenship, or move across to the other country.

Where it occurs

• Countries: India and Bangladesh. The two governments carried out the deal, and the Indian Parliament approved it in 2015.
• The 51 Bangladeshi enclaves (now India): all in Cooch Behar district, West Bengal [1][2].
• The 111 Indian enclaves (now Bangladesh): in Panchagarh, Lalmonirhat, Kurigram and Nilphamari districts of Bangladesh [1][2].
• The border it settled: 4,096.7 km long, touching five Indian states [3]:

• West Bengal (2,216.7 km) > Tripura (856 km) > Meghalaya (443 km) > Mizoram (318 km) > Assam (263 km) [3].

• Linked sea settlement: the Bay of Bengal maritime boundary between the two countries was settled separately by arbitration (a ruling by a neutral tribunal that both sides agree to accept) in 2014.

Don't confuse with

• Indira-Mujib Agreement (1974): this is the original LBA, and it was signed but never fully carried out. The 2015 step (100th Amendment) is what actually put it into effect.
• Bay of Bengal maritime boundary (2014): this settled the sea border through arbitration by a tribunal. The LBA settled the land border through an agreement between the two countries.
• Enclave vs adverse possession: an enclave is land of one country lying fully inside the other country. Adverse possession is land that belongs to one country but is held and farmed by the other country's people. On enclave land India gave away more; on adverse possessions India gained more.
• Ganga Waters Treaty (1996): this is a water-sharing treaty, with water shared at Farakka [4]. It has nothing to do with land or enclaves.

Prelims Hooks

• LBA was put into effect through the Constitution (100th Amendment) Act, 2015. Enclaves were exchanged at midnight on 31 July 2015.
• 111 Indian enclaves (in Bangladesh) were swapped for 51 Bangladeshi enclaves (in India), 162 in total [1][2]. Trap: India gave 111 and received 51, not the other way round.
• All 51 Bangladeshi enclaves were in Cooch Behar, West Bengal [1][2].
• In adverse possessions, India received 2,777.038 acres and transferred 2,267.682 acres, a net gain for India [1][2].
• Order of steps: 1974 Indira-Mujib Agreement → 2011 Protocol → 2015 100th Amendment.
• About 6.1 km of undemarcated border in three sectors was fixed. The enclave population was about 51,549 [1].

Mains Points

• The LBA shows how a border dispute can be settled peacefully (GS-I/GS-II link):
• Swapping 162 enclaves ended the stateless life of about 51,000 people, who got schools, police and ID papers [1].
• Residents chose their own citizenship, so no one was forced to move.

• Settling adverse possessions and the 6.1 km gap gave a clear line that can be marked on the ground.

• The land still makes border management hard (GS-III):

• Even after the LBA, shifting rivers, chars and crowded plains mean 864.482 km is still unfenced, and 174.514 km cannot be fenced at all [3].
• This keeps smuggling (cattle, drugs, fake currency) and illegal migration live problems.

• Possible fixes: "smart" fencing with sensors, river patrols by boat, and border haats (border markets) for legal trade.

• Land and sea settled together: the LBA (2015) and the 2014 sea-boundary ruling settled both borders. The sea ruling also opened the Bay of Bengal for fishing and oil and gas exploration, which helps build trust for open issues like Teesta water sharing.
