Importance of Teesta for Sikkim’s Ecology

The river carves deep valleys as it flows through Sikkim, creating lush, fertile basins that support diverse ecosystems. The surrounding areas are rich in flora and fauna, with dense forests, rhododendron groves and unique wildlife thriving near the riverbanks. Sikkim is known for its rich biodiversity, and the Teesta River basin is crucial for maintaining this. The forests and wetlands along the Teesta support species such as red pandas, snow leopards and countless bird species.

Economic Significance

One of the major relationships between the Teesta and Sikkim is the river’s use for generating hydropower. Sikkim, with its steep terrain and high rainfall, is well-suited for hydropower projects. A series of dams and hydropower stations have been constructed along the Teesta, making it a key source of electricity for Sikkim and India. One of the largest and most significant dams is the Teesta V Dam, located in East Sikkim, which produces a significant portion of the state’s hydropower. Other projects are planned or already operational, but these have raised environmental and social concerns regarding the displacement of communities and ecological impact. While the upper reaches of the Teesta are primarily used for hydropower, the river’s water is also crucial for irrigation in Sikkim’s lower regions. The fertile river valleys support the cultivation of crops such as maize, rice cardamom, which are staples for the local population.

Cultural and Spiritual Significance

The Teesta is not only a geographical feature but also a part of Sikkim’s cultural identity. It is considered sacred by the local communities, particularly the indigenous Lepcha people, who revere the river as a divine entity. The river has inspired folklore, songs and local traditions that tie the people of Sikkim to the natural landscape. In Lepcha folklore, the Teesta and its tributary, the Rangeet River, are believed to be lovers, and their confluence is a sacred site. This underscores the spiritual bond that many people in Sikkim feel with the river.

Environmental Challenges

While hydropower is a significant economic resource, it has also posed environmental challenges. The construction of dams has altered the natural flow of the river, affecting fish populations and the ecosystems dependent on the river. There is concern over the displacement of local communities and the degradation of the river’s natural beauty due to ongoing development projects. The glaciers that feed the Teesta are receding due to climate change, which threatens to reduce the river’s water flow in the future. This has implications not only for Sikkim’s hydropower projects but also for agriculture, drinking water and biodiversity in the region.

Role in Adventure Tourism

The Teesta is also a significant part of Sikkim’s adventure tourism industry. The river, particularly in the stretches through East and South Sikkim, is renowned for its white-water rafting opportunities. The rapids vary in intensity, offering thrill-seekers a chance to experience the natural beauty of Sikkim while navigating the river’s powerful currents. The valleys and gorges carved by the Teesta River are popular with trekkers and nature lovers. Tourists come to witness the river’s dramatic scenery, from its fast-flowing rapids to its tranquil stretches bordered by green hills and snow-capped peaks.

Regional Cooperation and Water Sharing

The Teesta flows from Sikkim into West Bengal and eventually Bangladesh, making it a transboundary river that is central to water-sharing discussions. The flow of water from Sikkim directly impacts West Bengal and Bangladesh, both of which depend on the Teesta for agriculture, drinking water and livelihoods. The hydropower projects and water use in Sikkim have implications for the amount of water flowing downstream. Although Sikkim’s projects primarily generate electricity, they influence the overall water availability in the lower parts of the river. The balance between development and maintaining natural river flows is crucial in the broader water-sharing dispute between India and Bangladesh.

Water Sharing Challenges of Teesta

Teesta River originates in the Indian state of Sikkim, flows through West Bengal, and enters Bangladesh before merging with the Brahmaputra River. It plays a very important role in the livelihood and economy of both the countries in relation to irrigation, livelihoods and supply of drinking water. For Bangladesh, the Teesta is the lifeline of the northern regions, particularly in the dry season when water scarcity is severe.

The Teesta River thus happens to be a subject of a water-sharing dispute between India and Bangladesh. Since the river flows into Bangladesh after traversing through Sikkim and West Bengal, both countries have serious aim and objective of utilizing its waters for irrigation and drinking purposes. While there have been several rounds of negotiations between India and Bangladesh, a final agreement on the equitable sharing of the Teesta’s waters is yet to be reached.

Political dynamics between India and Bangladesh have complicated the water sharing mechanism of Teesta. The state of West Bengal, through which the Teesta flows, has consistently opposed any water-sharing agreement that they believe would negatively affect its agricultural and economic needs. West Bengal depends heavily on the Teesta for irrigation, and the state government argues that releasing more water to Bangladesh could harm local farmers, especially during dry months. Sikkim, where the Teesta originates, is also a key player due to the construction of dams and hydropower projects, which regulate water flow downstream. Hydropower development in Sikkim has reduced the amount of water available to both West Bengal and Bangladesh.

India and Bangladesh have held numerous rounds of negotiations to resolve the Teesta water-sharing issue. While both countries recognize the importance of cooperation, domestic political pressures, particularly from the Indian states of West Bengal and Sikkim, have stalled the process. The unresolved water-sharing dispute has also become a sensitive issue in India-Bangladesh relations. Bangladesh has raised the issue in international forums, and water-sharing tensions are sometimes linked to broader diplomatic and trade issues between the two nations.

Bangladesh’s Concern

Bangladesh faces acute water scarcity in the dry season from the months of December to May, when the flow of the Teesta reduces drastically, affecting agriculture, livelihoods and drinking water availability. The northern part of Bangladesh, which depends heavily on Teesta waters for irrigation, suffers from drought-like conditions, leading to reduced crop yields and economic distress. The reduced water flow into Bangladesh has also negatively impacted the ecology of the Teesta basin. The river’s natural flow is critical for maintaining fish habitats, groundwater recharge and preventing soil degradation. In times of scarcity, the riverbed dries up, impacting the environment and local communities.

Impact on Irrigation and Economy

Both sides of the Teesta River basin are heavily dependent on the river for irrigation, especially during the dry season. In West Bengal, the Teesta irrigates large tracts of agricultural land, providing water for rice and other crops. In Bangladesh, particularly in the northern districts, millions of people rely on the Teesta’s waters for agriculture and sustenance. Any reduction in water flow can have significant economic consequences. Farmers in both India and Bangladesh are vulnerable to water shortages, and disputes over water sharing have led to local unrest in some areas. India’s construction of hydropower dams along the Teesta in Sikkim has reduced the water flow downstream, particularly during the non-monsoon months. This has fuelled Bangladesh’s concerns, as reduced water flow affects both irrigation and ecosystem health. The dams, while beneficial for energy generation in India, have become a point of contention in the water-sharing debate.

Solution to Teesta Water Sharing Dispute: Way Forward

A sustainable Teesta water distribution solution requires a balance between the water needs of both the countries: India and Bangladesh. Both countries must consider equitable water distribution, taking into account the environmental and social impacts of reduced water flow.

Climate change adaptation, improved irrigation practices and better water management will definitely help mitigating the impact of water shortages. Joint efforts in these areas could pave the way for a more cooperative approach to water sharing.

Achieving a permanent solution requires political commitment at both the national and regional levels, particularly addressing the concerns of West Bengal and Sikkim.

Teesta water-sharing dispute is a complex issue involving environmental, political and economic factors. While there is hope for a solution, it requires both India and Bangladesh to navigate domestic pressures and regional diplomacy to ensure equitable water distribution for both nations.
