This week brings a heartening development: Legal Initiative for Forests and Environment (LIFE), headed by lawyers Ritwick Dutta and Rahul Choudhary, are recipients of the Right Livelihood Award 2021, also known as Alternative Nobel Prize for their amazing work on empowerment of the communities through environment defense.

LIFE is one of four organisation to get this award this year. The Swedish Right Livelihood Foundation, which awards the prize, said that in the face of the worsening climate crisis, powerful governmental and corporate interests, and even a terrorist threat, the 2021 Laureates prove that solidarity is key to a better future for all. The 2021 Right Livelihood Laureates are leaders in advancing the rights of women and girls, environmental protection and reclaiming Indigenous rights through mobilising communities and empowering grassroots initiatives. “Hailing from Cameroon, Russia, Canada and India, this year’s change-makers show that lasting change is built on communities banding together,” it said.

Floods & Flood Monitoring in Yamuna: July 2018

The release of around 1.31 lakh cusecs of water in Yamuna from Hathnikund barrage at 09:00 hours on July 26, 2018, was certainly first surge of flood this monsoon in the river. But no one expected, most are still in the dark that the release would multiply by over five times in just two days! It is almost a month after the Southwest monsoon arrived. By this time the river usually floods couples of times.

Looking at the lack of significant rainfall in the catchment area over past weeks, the flood is unexpected and has taken many by surprise. The Irrigation and Flood Control Department, Delhi Government has issued warning for flood plain farmers and human settlements close to river banks, but the warning does not seem to commensurate with the flood peak that is likely to hit the capital in next day or two.

Yamuna has already crossed warning (204 m) and danger level (204.83) at Old Delhi Railway Bridge (ORB), Delhi. The High Flood Level is 207.49 meters, reached on Sept 6,1978 after around 7 lakh cusecs (cubic feet per second) water was released in Yamuna on 3rd Sept 1978 at 04:00 hrs from Tajewala barrage, that was decommissioned and replaced by Hathnikund barrage in early 1990s. The flood monitoring of River Yamuna began in 1963.

Since then, the river has seen high floods in 1988, 1995, 2010 and 2013. The 2010 and 2013 floods also crossed 207 metres mark but fell short of 1978 level.
