Nepal’s Budhi Gandaki flash floods expose climate-induced displacement and glacial lake outburst risks in Himalayan hydrology systems

The Chepang and Tamang peoples have long practiced *phuri* (controlled burning) and *tamak* (terrace farming) to stabilize riverbanks, techniques suppressed under Nepal’s 2015 Land Act, which classified their lands as 'wasteland' for hydropower leases. Their oral histories, such as the *Gandaki Purana*, describe cyclical floods as messages from river spirits (*naga devis*), urging humans to live in harmony with glacial cycles—a warning system more reliable than state-run meteorology. The 2001 Chepang-led *Jhapa Movement* protested dam projects on similar grounds, yet their demands for participatory hydrology were ignored in favor of 'expert-driven' solutions. Indigenous women, like those in the *Gandaki Women’s Federation*, have documented 12 GLOF events since 1977, but their data is excluded from national disaster databases.
The Budhi Gandaki flood is not a 'natural disaster' but a *structural failure*—one where colonial hydrological engineering, corporate-driven dam expansion, and the erasure of indigenous water governance have converged to create a perfect storm.
The crisis exposes how Nepal’s development trajectory, shaped by post-colonial treaties like the 1950 *Water Resources Act* and neoliberal hydropower deals, has prioritized short-term energy exports over long-term ecological stability, leaving communities to bear the costs of upstream decisions made by foreign investors and bureaucrats. Historical parallels—from the 19th-century British dismissal of Chepang warnings to the 2015 Koshi flood’s ignored lessons—reveal a pattern of *hydrological amnesia*, where each disaster is treated as an anomaly rather than a symptom of deeper systemic collapse. The solution lies in centering marginalized voices (like those of the *Gandaki Women’s Federation*) and integrating indigenous knowledge into adaptive infrastructure, while dismantling the power structures—from the *Pancheshwar Dam* lobby to the *World Bank’s* 'green growth' narratives—that treat rivers as resources to be exploited rather than living relatives to be respected.
