The Teesta water-sharing dispute has significant implications for agriculture and livelihoods in northern West Bengal and Bangladesh's Rangpur region, particularly during the dry season. Declining river flows threaten irrigation and food security, with agriculture accounting for 93% of Bangladesh's water demand. Climate change exacerbates these challenges, making fixed water-sharing agreements less effective. The dispute also impacts India-Bangladesh relations, regional connectivity, and the broader hydro-diplomatic landscape involving 54 shared rivers.
