East — the Sapta Koshi River (also the provincial boundary). West — the Balan River, separating Saptari from Siraha. North — the hills of Udayapur and the Mahabharat range. South — Supaul and Madhubani districts of Bihar, India, across an open border that shapes daily life and trade.
The Sapta Koshi — Nepal's largest river system of seven Himalayan tributaries — dominates the east; the flashy Balan and Khando and the seasonal Mahuli and Jita cross the district. Rising riverbeds and monsoon inundation make flood-risk management a defining development challenge. Rivers & corridors →
Established 1976; 348 km² plus a 173 km² buffer zone; Nepal's first Ramsar site (1987). Home to the wild water buffalo (arna), Gangetic dolphin and endemic fish, and one of Nepal's Important Bird Areas. About 215 settlements depend on the wetland.
~65% cultivated — one of the Terai's granaries (paddy, wheat, maize; second among Terai districts for vegetables). ~15–16% forest, concentrated in the Chure. Part of Nepal's principal mango belt, with a well-known fish-farming economy.
~30% under 15, 63% of working age, 7% over 65. Foreign employment shapes household economies — roughly 11,000 new labour approvals in FY 2021/22, with the diaspora a key campaign constituency.
Maithili is the largest mother tongue (over 90% in Rajbiraj), followed by Tharu; Urdu and Nepali are spoken by minorities. Saptari has the highest Tharu share of any Madhesh district and is a heartland of Maithili literature.
Madheshi communities are the largest group (about a third of whom are Dalits — Musahar, Khatwe, Chamar, Mallah and others); Muslims are nearly 10% of the population. This diversity is central to Saptari's identity.

Agriculture is the mainstay, supplemented by remittances, fish farming and agro-based industry. The Rajbiraj customs point at Kunauli and sub-customs posts link the district to Bihar; much of the borderland economy runs through everyday informal exchange. Trade facilitation, agro-processing and diversification are high-value opportunities.
Saptari was an early testing ground for solar irrigation — over a hundred AEPC-subsidised pumps (2016–19) and ICIMOD pilots that raised cropped areas ~28–30% while cutting diesel use. Scaling decentralised solar is a core campaign opportunity.
Chhinnamasta Bhagawati (a Shakti Peeth), Kankalini Temple at Bhardaha, and Shambhunath Temple with its Siruwa Mela draw pilgrims from Nepal and India. Mithila art, Maithili literature and the Koshi Tappu wetlands anchor a largely undeveloped tourism economy.
Planned in the late 1930s as a miniature of Jaipur to resettle Hanumannagar after Koshi floods, Rajbiraj is one of Nepal's oldest planned towns — a heritage of national significance that the campaign works to protect.
