Assam
The land of two great river valleys — home to GI-tagged Joha rice, Assam tea, and one of India's richest agro-biodiversity corridors.
Assam's Brahmaputra Valley is one of the most fertile agricultural regions in Asia, fed by annual flooding that deposits fresh alluvial silt across the floodplain. This natural fertility has sustained an extraordinary diversity of indigenous rice varieties — including the aromatic Joha (Jaha Chaul) family, which encompasses over 14 documented sub-varieties. The valley's traditional agricultural calendar is tied to the Bihu festivals: Bohag Bihu (spring planting), Kati Bihu (mid-season), and Magh Bihu (harvest). Joha rice — particularly Bokful Joha and Rangi Joha — is offered in Bihu rituals and represents the intersection of agrarian practice and cultural identity. The northeastern frontier also produces some of India's most distinctive organic tea, large cardamom, and Bhut Jolokia (Ghost pepper).

— Traditional Farming Systems
- Bihu agricultural calendar (3 festivals marking planting, mid-season, and harvest)
- Floodplain cultivation using annual silt deposition as natural fertilizer
- Community seed festivals — Nongkrem and Ali Ai Ligang
- Women-led seed selection for aromatic varieties
— Challenges Facing This Region
Annual flooding increasingly unpredictable due to climate change; Brahmaputra embankment failures; loss of traditional aromatic rice varieties to high-yield modern varieties; tea estate monoculture expanding at cost of rice biodiversity.
