Strategies to weather drought
THE EDITOR, Sir:
I have observed in the press lately that all talk of drought mitigation is focusing on sucking the land dry of every last remaining drop of groundwater. This is a prescription for disaster.
I recommend (again, as many have done so before) three strategies for mitigation against drought.
1 Make covered water tanks compulsory. Every building should have a tank that stores at least three days' supply. It should be compulsory for all new construction and phased in for already-existing structures. This will multiply the storage capacity and protect it from evaporation.
2 In the short term, return to the 1980s practice of cloud-seeding to produce rain. The technology has improved significantly and the same mistakes should not recur.
3 In the long term, build and commission desalination plants powered by wind turbines at breezy coastal locations. Pump the purified water to storage tanks uphill, above populous towns and cities. A short pipeline could keep the Mona Reservoir permanently full.
With these measures, we could have a consistent water supply. Stop the chatter about damming the Rio Cobre, and decommission the Yallahs pipeline to return St Thomas to its former green glory.
