Anyone know if this 3x rain is even 1.5x as effective in recharging aquifers? Iirc Punjab (across both India and Pakistan) has had a groundwater pumping rate of 3x recharge rate which is why entire northern subcontinent has been on the brink of water table collapse for years…

By the end of August Pakistan had received three times its annual average rainfall. Why is it getting so much rain? econ.st/3AFkPbc

I briefly studied this stuff 20y ago… without a proper system of small local check dams (not huge dams), and other local watershed management methods, you capture about 4% of rainfall. If you do it right, it rises 5x to about 20%. I’d guess globally the situation is closer to 4%

You’d think a developed country region like California would be better but it isn’t. Everybody is now scared of a mega flood that doesn’t improve water situation but breaks things.

There is some recharge but the water is mostly flowing downcountry and now there is a gigantic lake covering all of sindh, half of Balochistan and the bottom half of punjab. No drainage into ocean from here so the eventual end is a fetid swamp.

Flooding and droughts are highly correlated with solar cycles, whole body of research predicted an early spike in droughts and flooding leading into 2024, as early as 2022.
