It has rained, in all that time, on 2 (two) days. And that was drizzle that didn't last very long.
For "times" read climate! Not that Trump would recognise that. As far as he is concerned, more false news!

Much of India is affected by drought with some areas reliant on water tankers.
Many wells have dried up and others yield water of doubtful quality.

Looks to me like a mixture of climate change, overpopulation, and poor planning.

I have worked a couple pf projects that used directional boring and HDPE plastic pipe to good effect. One project installed a mile long system of four inch pipe that crossed under all streets without cutting any pavement and each house connection required only an eight foot square pit in the lawn. Historic and ornamental trees and shrubs were bored under without any disturbance to their roots. On another project six inch pipe was bored under wetlands and existing drainage culverts without the need for wetland mitigation permits or measures.
If bedrock or rock fill is not present this can be a way to install a modern leak free system without subjecting the neighborhood to a summer of excavation and repair with all the attendant dust and disruption. Pipe sizes up to and beyond one meter in diameter can be installed with the right equipment. The units I was working with could handle 18 inch pipe if needed.
Of course bedrock is a no go so when I replaced 1000 feet of my own water line I open cut all of it as the bedrock was never more then three feet down. You have to match your solution to the actual field conditions.

India’s ground water problem is decades old. Ground water levels are now at least tens of metres below ground level.

I have heard that in some parts of Northern India the wells have to be redug as the water table is falling every year sometimes by several metres. A case of drill-baby-drill perhaps?
Overpopulation is indeed part of the problem but India's total fertility rate of 2.33 has fallen a lot and is still falling. I understand they have a big problem with illegal immigration from Bangladesh.
I am not certain all of it is due to climate change. More classic over exploitation of underground water resources that are slow to replenish. I think parts of the US had the same problem with the Oglalla aquifer and may still do.
On a personal note my water tanks in Australia are nearly empty, partly due to my working away and neglecting the irrigation system and partly due to a drought here as well. I understand that Sydney people can only water their gardens at certain times of the day or certain days of the week due to reservoirs falling below 50% levels.

The current drought in South Africa is said to be the worst ever, with some districts having had no significant rain for five years.

Interesting video. I am happy with the BBCs scientific content being fair, even RT and AlJazeera. It is when they start talking politics is when the BS filter needs to go into operation.adam2 wrote:The current drought in South Africa is said to be the worst ever, with some districts having had no significant rain for five years.

In Australia it has certainly not rained as much in the last few years as before. We would get 50mm per month a few years ago but now it is generally about 20mm per month usually all in one go. You have to be ready to catch it when it does come. it rained 10mm a few nights and I collected about 2000 litres from the roof runoff. It should last about 2 weeks watering the garden.
Supposedly most of the rain in Australia comes from the Indian Ocean and the "Indian Ocean Dipole" is not currently favourable for this. Then there are stronger winds than expected around Antarctica keeping rain fronts too far south for Australia.
G'Day cobber!
