BharatNotes Phumdis
noun (plural; singular "phumdi")Usage in a UPSC answer
The unchecked proliferation of phumdis on Loktak Lake, accelerated by the Ithai barrage and nutrient run-off, illustrates how a fragile wetland ecosystem and the livelihoods dependent on it can be imperilled when developmental projects ignore hydrological balance.
Synonyms

Word Family
phumdi (n singular), phumdis (n plural)
Root
Meitei (Manipuri) phum ("earth/soil") + collective/locative suffix; vernacular ecological term for floating organic mats on Loktak Lake
Etymology
From Meitei (Manipuri) language — phum ("earth/soil") + the locative/collective suffix; the phumdis are formed over centuries as dead and decaying organic matter accumulates on the lake surface, creating buoyant mats that can be thick enough to support human habitation and agriculture.
Memory Hook
"PHUM-floats" — picture a soggy mat that goes "phoom" as it bobs up on the lake; phumdis are vegetation rafts that float on Loktak.
How This Word Works in UPSC Writing
Floating masses of vegetation, soil and organic matter on Loktak Lake in Manipur. Their significance is that they support Keibul Lamjao, the world's only floating national park, and with it the last wild population of the Sangai, the brow-antlered deer that is Manipur's state animal. The ecological story is really a governance case study, because the Ithai barrage built for hydropower holds the water level artificially constant, whereas the phumdis historically sank in the dry season to root in the lake bed and take up nutrients before rising again with the monsoon. Permanent inundation prevents that cycle, so the mats thin and lose the strength that bears the weight of the deer, while nutrient run-off from the catchment accelerates their proliferation elsewhere on the lake. The lesson generalises well: a single-purpose intervention optimised one variable, water level for power generation, and destroyed the seasonal variation on which the whole system depended.
Don’t Confuse It With
Phumdis are floating mats of vegetation and organic matter, while athaphums are the artificial circular phumdis built by fishers for aquaculture and are a human modification rather than a natural feature. Keibul Lamjao is the national park they support, the only floating one in the world. The Sangai is the brow-antlered deer found nowhere else in the wild. Loktak is the lake itself, a designated wetland of international importance, and the Ithai barrage the structure that fixed its water level.
Hindi Meaning
फुमदी (phumdī); संगाई (sangāī) for the brow-antlered deer.
Common Questions
- Why does the Ithai barrage harm the phumdis?
- It holds the water level constant, preventing the phumdis from sinking in the dry season to root in the lake bed and absorb nutrients, so they thin and lose the strength that supports the deer.
- What is Keibul Lamjao National Park?
- The world's only floating national park, on Loktak Lake in Manipur, protecting the Sangai or brow-antlered deer, whose last wild population lives on the phumdis there.
