This paper published in the South Asian Journal of Tourism and Heritage describes the water quality status of Gundolav Lake in Rajasthan, which was once used for drinking water as well as for recreational activities under the tutelage of the princely state of Kishangarh. This has now become a site of wastewater disposal and facing a critical threat for its sustenance. Read More
Recent years have led to an increasing awareness of the importance of water bodies and the need for conservation of water bodies, especially freshwater wetlands. The Ramsar Convention (2002) identifies wetlands as the starting point for integrated water management strategies. This is because they are the source of fresh water, maintain the health of the water course and water bodies, have the capacity to supply water to meet the human needs and are a key to future water security.

Measurement of riverine biota, particularly benthic macroinvertebrates (such as crustaceans and aquatic insects) and fish, has become a widely accepted method of identifying the structural or functional integrity and the overall health of a riverine system. This manual from the 
The Vembanad estuarine system, the largest of its kind on the west coast of India is known to be abundantly enriched with diverse fishery resources, providing feeding, spawning and rearing areas for a very large proportion of commercial (fin) fish and shellfish. However, ecosystem health of the Vembanad wetlands is alarmingly declining due to a variety of reasons - obstruction of river courses, sand mining & habitat destruction, loss of riparian canopy cover, encroachment, pollution and unethical fishing practices. Reduced summer flow due to drying up of rivers and pollution hazards from agro-chemicals and sewage also lead to mass mortality of fishes. Depletion of fishery resources has changed this ‘inland fish basket’ to an ‘inland wastebasket’, driving the fisherfolk, the primary stakeholders of the lake into a livelihood crisis.
