Explained: What is the Teesta River Project and why does it matter to India?
Teesta River Project: Discover why the Bangladesh Teesta River comprehensive management and restoration project backed by China is raising major security issues for India near the strategic Siliguri Corridor.
Bangladesh designed the Teesta River Comprehensive Management and Restoration Project. A multi-billion-dollar plan to revive and manage the river and its tributaries. Bangladesh agreed to the Chinese financial and technical backing for the project. The increasing involvement of China’s infrastructure developments in Bangladesh is triggering India’s border issues like its proximity to the Siliguri Corridor a significant choke point that connects northeast India with the rest of the mainland.
What is Teesta River Project?
The Teesta River Project is a comprehensive management and restoration project that is designed to restore and manage a 100 KM stretch of the Teesta River in the Bangladesh territory. Indian and Bangladeshi formal transboundary water-sharing treaty with India has been stalled so Bangladesh pivoted to a localized engineering solution and with China's involvement.
The main objective of the project is to address Bangladesh's seasonal water crises. Its core features include river dredging to deepen the silted riverbed to prevent seasonal overflow of the water.
Embankment construction on the river banks as barriers to stop soil erosion that caused the displacement of families. Construction of large internal water reservoirs for harvesting and restoration of monsoon water for the dry seasons. Creating a large network of canals to safeguard agricultural productivity across the Teesta basin.
Teesta River Origins, Basin and Tributaries
Teesta River originates in the Eastern Himalayas at the Tso Lhamo lake in Sikkim, India. It passes through the mountainous terrain of Sikkim and flows down into the plains of West Bengal and makes the international border into northern Bangladesh, where it eventually merges into the Brahmaputra River (called Jamuna in Bangladesh).
The total length of the river is approx. 414 Km, supporting millions of livelihoods. Its tributaries include the Rangpo River, Kanaka River Zemu Chhu and Great Rangeet River.
The main problem of the Teesta River is controlling the upstream points including the Gajaldoba Barrage, which is entirely in Indian territory which helps India to control the water flow of the Teesta River.
Why Does it Matter to India?
The project is based on internal, humanitarian and climate resilience. However, it matters to India due to its geographical proximity to north east of India. The main reason is the presence of Chinese state-owned construction companies and engineers working on a project in the neighborhood near the international boarder which views regional water bodies as sensitive bilateral matters.
Building major infrastructure without a unified transboundary data sharing blueprint with upstream and downstream India makes the projects long term sustainable unpredictable.
