The Terai — from the Urdu word tarāʼī, meaning "lands lying at the foot of a watershed" — is one of the most fertile and biodiverse stretches of land on earth. It runs in a vast belt south of the Shivalik Hills and north of the Indo-Gangetic Plain, stretching from the Yamuna River eastward across Uttarakhand, Uttar Pradesh, Bihar, and West Bengal — a 810-kilometre arc of alluvial richness at the very base of the Himalayas.
The great perennial rivers — the Yamuna, Ganges, Sarda, Karnali, and Kosi — cascade down from the mountains and deposit centuries of Himalayan silt across this lowland belt. The result is some of the most nutrient-rich agricultural soil in all of Asia.
This land is also home to over 120 distinct ethnic communities — each with their own dialect, festivals, and kitchen traditions. It is in those kitchens, generation after generation, that Buka Laal Namak was born.
