Introduction

Wetlands are ecosystems where land and water interact to support rich biodiversity, regulate hydrological cycles, and sustain livelihoods. In India, they function simultaneously as ecological lifelines and economic assets, yet are among the most degraded ecosystems today.

As Ecology:
Wetlands act as natural sponges that absorb floodwaters, recharge groundwater, purify water, sequester carbon, and moderate microclimates. They provide critical habitats for migratory birds, fish, amphibians, and aquatic plants. Coastal wetlands such as mangroves buffer cyclones and prevent shoreline erosion, while floodplain wetlands maintain river health.

As Economy:
Millions of Indians depend on wetlands for fishing, paddy cultivation, fodder, handicrafts, and eco-tourism. Traditional systems like kulams of Tamil Nadu, kenis of Wayanad, and fishing wetlands of Srikakulam demonstrate how wetlands have historically supported sustainable livelihoods while conserving ecosystems.

Why They Are Threatened:
Despite this value, nearly 40% of India’s wetlands have vanished in the last three decades, and about half of the remaining show ecological stress. Rapid urbanisation, land conversion, encroachments, infrastructure projects, and real estate expansion have replaced wetlands. Altered hydrological flows due to dams, embankments, sand mining, and groundwater extraction disrupt their natural functioning. Pollution from untreated sewage, industrial effluents, agricultural runoff, and solid waste leads to eutrophication and biodiversity loss. Weak enforcement, fragmented governance, and capacity constraints further aggravate the crisis.

Way Forward:
Wetland conservation must shift from cosmetic “beautification” to ecological restoration. This requires basin-level governance, strict demarcation and notification, wastewater treatment before inflows, catchment protection, community participation, and integration of traditional knowledge with scientific monitoring.

Thus, safeguarding wetlands is not a choice but a necessity for India’s ecological security and economic resilience.
