Community water purification system in a Delhi urban slum
Women swipe clean drinking water through an automated dispensing unit at the Lalbagh slum. Posted on 22 Feb, 2020 12:38 PM

It’s a dull reality that the state of water in the urban slum of Lalbagh near Azadpur in north Delhi was awful till a few years back. Hoards of people would queue up to get water from the public taps or the tankers along the road. Life was tough here and people got access to piped water supply only recently.

Once selected for the role, the women entrepreneurs were trained to run the community filtration plant and overlook all operations ranging from the management of customers to the plant finances. (Image: India Water Portal)

I am thirsty as hell and would do anything to find a seemingly elusive little glass of water, but I can’t.

Perils, politics and prospects of groundwater in India
How can India change the game on groundwater management to deal with its overexploited aquifers? Posted on 05 Feb, 2020 03:15 PM

After independence, India was largely food insecure but post Green Revolution around the 1970s, foodgrain production increased manifold consequently reducing food insecurity and poverty in the country, in spite of rapid population growth. Its ability to achieve targeted results was largely dependent on the explosion of groundwater abstraction mechanisms like tubewells.
