Re: Self-Test 1: Sustainable Water Management - Excessive water pumping

Yes Rashid, you are absolutely correct - and lowering the water table will continue unfortunately in many places.

Re: Self-Test 1: Sustainable Water Management - Possible health impacts of irrigation

I agree Tanoh. In case the irrigation grid are not lined and water is leaking persistently, it may cause water logging and salinity and thus desertification. This is true for riparian agriculture. The statistic determined by UNO is alarming: search it further :)

Thanks,
Rashid

Best,

Rashid

Hi All, Excessive water pumping is an issue of particular concern in the urban setting in developing countries (urban slums). In my context, the construction of unplanned commercial plazas in residential areas lead to conflicts and dependence on tanker mafias. This is huge setback to urban forming w...
