A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation of aquatic plants.
They are reservoirs of biodiversity and provide a range of ecosystem services, which benefit us, including
- Groundwater replenishment: Wetland systems are directly linked to groundwater and a crucial regulator of both the quantity and quality of water found below the ground.
- Water purification: Many wetland systems possess biofilters, hydrophytes, and organisms that in addition to nutrient up-take abilities have the capacity to remove toxic substances that have come from pesticides, industrial discharges, and mining activities.
- Flood control and shoreline stabilisation: Tidal and intertidal wetland systems protect and stabilize coastal zones. Coral reefs and mangroves provide a protective barrier to coastal shoreline. Wetlands help to lessen the impacts of flooding by absorbing water and reducing the speed at which flood water flows.
- Nutrient retention: Wetland vegetation uptake and store nutrients found in the surrounding soil and water.
- Aquaculture: Wetlands are used to harvest fish/aquatic animals for human consumption and pharmaceuticals.
- Wetland products: It includes important products such as rice, honey from mangroves, fuel wood, salt, animal fodder, traditional medicines (e.g. from mangrove bark), fibres for textiles, dyes and tannins etc.
- Climate change mitigation and adaptation: Wetlands perform mitigation effects through their ability to sink carbon, and adaptation effects through their ability to store and regulate water.
- Recreational, historical, scientific, and cultural values: Wetlands such as Pushkar lake in Rajasthan are of significant religious, historical or archaeological value to many cultures around the world. They are often popular for recreational activities including hiking, fishing, bird watching, photography and hunting.
Despite its numerous benefits, India has lost nearly one-third of its natural wetlands over the last four decades as per Wetlands International South Asia (WISA). The causes of wetland loss in India include:
- Urbanisation: Unplanned urban development and resource extraction has led to encroachment, transformation and draining of wetlands.
- Hydrologic activities: Construction of canals and diversion of streams and rivers to transport water to lower arid regions for irrigation has altered the drainage pattern and significantly degraded the wetlands of the region.
- Agricultural activities: Following the Green Revolution, vast stretches of wetlands have been converted to paddy fields. Also, high fertiliser use stimulates algal growth, leading to eutrophication of surface water bodies. Intensive aquaculture: Demand for shrimps and fishes has provided economic incentives to convert wetlands and mangrove forests for development of pisciculture and aquaculture ponds.
- Invasive species: Indian wetlands are threatened by exotic plant species introduced such as water hyacinth and Salvinia. They clog waterways and compete with native vegetation.
- Climate change: Increased air temperature; shifts in precipitation; increased frequency of storms, droughts, and floods; sea level rise could also affect wetlands.
Therefore, the government has brought the Wetlands (Conservation and Management) Rules, 2016 to preserve the ecological character of wetlands through the implementation of ecosystem approaches.

Model Answer
The success of Project Tiger in Safeguarding Tigers
Project Tiger, launched in 1973, has played a crucial role in addressing the rapid decline of the tiger population in India due to poaching and habitat destruction. The project has successfully supported tiger population recovery and expansion of protected areas.
Challenges to Holistic Conservation
Despite significant progress, several challenges remain in ensuring the long-term survival of tigers.
Steps for Holistic Tiger Conservation
Conclusion
