What is the common examiner trap about Intl. Relations in UPSC exams?

They may confuse the Land Boundary Agreement signing year (1974) with its operationalization year (2015), or mix up the number of enclaves transferred (India gave 111, Bangladesh gave 51). They might also ask about the Radcliffe Line for India-Pakistan instead of India-Bangladesh.

What should UPSC aspirants remember about Intl. Relations for Prelims?

1. Target this Data: 4,096 km border length across five states. 2. Target this Nodal Body: Border Security Force (BSF) and Border Guard Bangladesh (BGB). 3. Target this Legal Point: 100th Constitutional Amendment (2015) enabling Land Boundary Agreement.

India-Bangladesh Border Demarcated Under 100th Constitutional Amendment, Land Boundary Agreement Resolves 162 Enclaves

Q: Which constitutional amendment enabled the implementation of the Land Boundary Agreement between India and Bangladesh?

100th Amendment, The article explicitly states that a breakthrough came in 2015 when the Indian Parliament unanimously passed the 100th Constitutional Amendment, enabling the implementation of the Land Boundary Agreement (LBA).

Q: Consider the following statements regarding the India-Bangladesh border: 1. The total length of the India-Bangladesh border is over 4,096 km. 2.

Under the LBA, India transferred 51 enclaves covering around 7,000 acres to Bangladesh. Which of the statements given above is/are correct?

Both 1 and 2, Statement 1 is correct as the article mentions the border stretches over 4,096 km. Statement 2 is correct as it states Bangladesh ratified the 1974 LBA quickly, while India did not initially due to constitutional constraints. Statement 3 is incorrect; the article says India transferred 111 enclaves (~17,000 acres), while Bangladesh transferred 51 enclaves (~7,000 acres). Hence, only statements 1 and 2 are correct.

Q: According to the Land Boundary Agreement operationalized in 2015, how many enclaves did Bangladesh transfer to India?

51 enclaves, The article provides the exact data: Under the Agreement, India transferred 111 enclaves and Bangladesh transferred 51 enclaves. The total number of enclaves exchanged was 162, but the question asks specifically for Bangladesh's transfer.

Complex Border Legacy

The Radcliffe Line created an unnatural frontier during Partition, leading to enclaves and adverse possessions that were resolved via the 1974 Land Boundary Agreement.

⚖️

100th Constitutional Amendment

In 2015, Parliament unanimously passed the 100th Constitutional Amendment to implement the LBA, enabling the exchange of enclaves and regularization of adverse possessions.

🛡️

Shift from Policing to Governance

Experts recommend moving from border policing to governance via smart fencing, high-tech surveillance, and economic development of border areas to address migration and crime.

Detailed Analysis & Strategic Depth

Context / Background

The India-Bangladesh border, the longest among India's neighbors, is a product of the hurried Radcliffe Line demarcation during Partition in 1947. This created enclaves and adverse possessions, which became major irritants. The foundational Land Boundary Agreement (LBA) was signed in 1974 by PM Indira Gandhi and Sheikh Mujibur Rehman, but India's ratification was delayed due to constitutional constraints over land transfer.

Core Analysis & Implications

The 2015 operationalization of the LBA via the 100th Constitutional Amendment was a landmark achievement, resolving territorial ambiguities and strengthening bilateral ties. However, the border remains a hotspot for illegal migration (linked to CAA/NRC debates), cross-border firing, transnational crime (smuggling, trafficking), and security concerns, especially with Rohingya refugee influx. The unresolved Teesta water sharing dispute adds friction and has seen Bangladesh appeal to China, raising strategic concerns for India.

Future Outlook / Way Forward

A 'border governance' approach involving smart fencing, tech surveillance, and institutionalized BSF-BGB cooperation is suggested. Economic development of border regions through trade corridors and connectivity projects (under BIMSTEC/BBIN) can reduce poverty-driven illegal activities. Minimizing civilian casualties and fostering political trust, especially with the new Bangladesh government under PM Tarique Rehman, are crucial for converting border complexities into zones of prosperity and regional stability.
