21 November is celebrated as world fisheries day across the world. Apart from crucial source of food and livelihood to lakhs of fisherfolks in India, fish diversity determines the health of the water body including lakes, ponds and rivers. However with growing threats and pollution mass fish mortality has been taking place in various rivers and lakes in the country every year. On World Fisheries Day 2019 SANDRP has put together known mass fish kill incidents that took place this past year to highlight the gravity of threat so that corrective measures can be taken by respective Governments and others concerned.
Ken Betwa river interlinking project is back to drawing board with Union water resources ministry approaching the ministry of environment and forest to relax conditions imposed as part of forest clearance accorded in May 2017 for diversion of forest in the Panna Tiger reserve (PTR).
Forest Advisory Committee (FAC) while according Stage-I clearance to the project had recommended that the project proponent and state govt should consider equivalent non-forest area (6,017 ha) adjoining to PTR from the revenue and private land and add to the PTR as a part of core/corridor (for tiger movement) with other areas or satellite core area. According to water resources ministry, they are unable to find land adjoining to PTR.
Will the forest department buckle under pressure to dilute the forest clearance conditions? http://www.newindianexpress.com/thesundaystandard/2018/nov/25/first-river-linking-project-coming-undone-1902890.html (25 Nov. 2018)
Accepting that reservoirs operation and flood management in India lack scientific supports, Madhavan Nair Rajeevan, Secretary, Ministry of Earth Sciences, in an interview has revealed that dams and water reservoirs need flood management systems that use scientific methods to understand when the time is right to open the gates.
“As per my understanding, no big reservoir has a decision support system. So we don’t know when to open them, how to open them… I am not attributing the Kerala floods to an individual. There is a common perception that in India most of the flood management systems are not supported by science… I am very sure we don’t have the decision support system and we need it.” https://indianexpress.com/article/india/not-just-kerala-no-scientific-dam-water-management-across-india-madhavan-nair-rajeevan-secy-earth-sciences-5322003/ (24 Aug. 2018)
In another interview he says that while Kerala records among the highest amounts of rainfall in the country, the State did not have a flood warning system in place. He added that while there were several sophisticated tools to anticipate extreme weather events, India still lacked a mechanism to effectively deploy them. https://www.thehindu.com/sci-tech/energy-and-environment/reservoirs-not-managed-using-a-scientific-decision-support-system-m-rajeevan/article24785253.ece (26 Aug. 2018)
Further in a detailed interview, he pitches for ‘decision support systems’ at dams, acknowledges the challenge of climate change, warn against repercussions of ‘fast-warming’ Indian Ocean. https://indianexpress.com/article/india/kerala-floods-m-rajeevan-ministry-of-earth-sciences-met-department-5324840/ (26 Aug. 2018)

About Rajasthan Rivers
Rivers in Rajasthan are mostly seasonal, but this fact explains little because a river is not just the surface flow, evident to a naked eye. All the rivers and their floodplains in this desert state are vast grazing grounds supporting millions of livestock. These unseen rivers also recharge the groundwater making well irrigation possible.
Modern-day development activities, however, are putting an enormous pressure on them. If deforestation has reduced the water flow, rampant sand mining has affected the water retention and seepage into subsurface channels. Aravallis also has large number of marble mines and processing units. While digging operations extensively damage the environment, discharge of a large amount of slurry by processing units also blocks water channels. Industrial and domestic wastewater has further affected the quality and biodiversity of rivers.
