The timeless rhythm of the Mekong

Nutrients carried by the Amazon River into the Atlantic Ocean help absorb significant amounts of carbon dioxide (CO2) from the atmosphere, new research reveals. The nutrients fertilize a type of plankton that the researchers estimate to consume 27 million metric tons of CO2 annually.

Ganga is one of the largest rivers of the world which supports millions of population on its banks. It is a tectonically controlled Himalayan river which also creates havoc due to perennial floods every year. Like most large river systems, it also shifts its course in the Gangetic plains in space and time.

The analysis presented in this paper shows that in water-scarce regions of India, run-off harvesting does not offer any potential for groundwater recharge or improving water supplies at the basin scale. The issues are many: (1) Water harvesting in the

The paper presents the outcomes of a study conducted to analyse water resources availability and demand in the Mahanadi River Basin in India under climate change conditions. Climate change impact analysis was carried out for the years 2000, 2025, 2050, 2075 and 2100, for the months of September and April (representing wet and dry months), at a sub-catchment level. A physically based distributed hydrologic model (DHM) was used for estimation of the present water availability.

On June 13 when Dr GD Agrawal, the eminent 76-year-old environmental scientist started a fast unto death to protest indiscriminate dam building on the Bhagirathi Ganga river, many wondered whether his gesture would be in vain. The government, by and large, turns a deaf ear to such protests. Two groups, who could not be more unlike each other, took up the cause. The Alumni Association of IIT Kanpur and the All India Association of Sadhus met the Union Government and lobbied with the state government of Uttarakhand. And, surprisingly, Dr Agrawal scored a major victory.
