Understanding the Teesta Water-Sharing Treaty and Its Implications

Introduction

The Teesta water-sharing treaty between India and Bangladesh has been a contentious issue for over a decade. Recent remarks by Prime Minister Narendra Modi, during a visit by Bangladesh Prime Minister Sheikh Hasina, have reignited discussions about this critical bilateral agreement.

What Is Holding Up the Teesta Treaty?

The treaty has faced delays primarily due to disagreements, especially from West Bengal. The 2011 proposal indicated that India would receive 42.5% and Bangladesh 37.5% of the river water from December to March. However, West Bengal Chief Minister Mamata Banerjee has opposed this allocation, claiming it would severely impact the livelihoods of people in northern Bengal.

What Has the Indian Government Told Bangladesh?

Following Modi’s comments, Foreign Secretary Vinay Kwatra emphasized that the discussions were more focused on water flow management rather than water sharing. A technical team is set to visit Bangladesh to explore conservation and management strategies for the Teesta river.

Geography and Importance of the Teesta River

• Origin and Course: The Teesta river originates from Tso Lhamo Lake in North Sikkim, at an elevation of about 5,280 meters. It flows 150 km in Sikkim and 123 km in West Bengal before entering Bangladesh, where it continues for another 140 km to join the Bay of Bengal.
• Tributary: It is a major tributary of the Brahmaputra river.
• Catchment Area: 83% of the river’s catchment area lies in India, while 17% is in Bangladesh.

Benefits and Importance to Both Countries

India

• Agriculture: The river supports significant agricultural activities in Sikkim and West Bengal.
• Hydropower: The Teesta is essential for hydroelectric power generation, with several dams and hydro projects along its course.
• Water Supply: It provides crucial water for drinking and irrigation in northern West Bengal.

Bangladesh

• Agriculture: The Teesta’s floodplain spans about 2,750 square kilometers, aiding 8.5% of Bangladesh’s population and contributing to 14% of its crop production.
• Economic Activities: The river is vital for fisheries, irrigation, and maintaining ecological balance.
• Flood Management: Proper management of the Teesta’s flow is essential to prevent floods and ensure adequate water supply during dry seasons.

Political and Environmental Considerations

• West Bengal’s Concerns: Mamata Banerjee argues that sharing Teesta water with Bangladesh could adversely affect the state’s agriculture and water supply, impacting millions.
• Bangladesh’s Needs: Bangladesh experiences erratic water flows due to hydro projects in India, leading to either floods or water scarcity, which affects agriculture and livelihoods.
• Environmental Impact: Both nations must address environmental concerns such as deforestation, climate change, and the effects of hydro projects on the river’s health.

The Ganga Water Sharing Agreement

• Background: India and Bangladesh established the Ganga water sharing agreement following the construction of the Farakka Barrage in 1996.
• Renewal: This treaty will be up for renewal in 2026.
• Current State: The treaty has altered the Ganga’s morphology, causing river erosion and displacement of populations in West Bengal while reducing silt load in the Hooghly river, impacting the Sundarban delta.

The Way Forward

• Technical Team’s Role: The Indian technical team will focus on conservation and management strategies for the Teesta river in Bangladesh.
• Bilateral Cooperation: Both nations must collaborate on sustainable water management practices, addressing all stakeholders' needs and concerns.
• Addressing Concerns: Solutions should include mechanisms to restore the river’s health, manage water flows effectively, and ensure equitable water distribution.
