Even Mod­est Green Ac­tion Can Pre­vent Wa­ter Short­age in Asia

Asian Diver (English) - - What Bubbled -

Ac­cord­ing to a new study led by MIT re­searchers, an in­no­va­tive ap­proach to modelling the ef­fects of cli­mate change and eco­nomic growth in Asia has un­cov­ered that even “mod­est” ac­tion can help pre­vent ex­treme wa­ter-short­age sce­nar­ios fac­ing Asia by the year 2050.

Ap­prox­i­mately 60 per­cent of the world’s pop­u­la­tion lives in Asia, of­ten with in­ad­e­quate ac­cess to wa­ter. Com­pared to the global av­er­age, Asians on av­er­age have less than half the amount of wa­ter avail­able to them. The MIT team found that by sim­ply com­bat­ing cli­mate change as set out in the

2015 Paris Agree­ment, there would be a re­duc­tion of 60 mil­lion peo­ple fac­ing se­vere wa­ter prob­lems.

The re­searchers ex­am­ined the pos­si­bil­i­ties of wa­ter short­ages in Asia by con­duct­ing de­tailed sim­u­la­tions of many plau­si­ble eco­nomic and cli­mate path­ways for Asia in the fu­ture.

They also eval­u­ated the ef­fects that eco­nomic devel­op­ment and cli­mate change had on the wa­ter sup­ply and de­mand. The re­searchers stud­ied cases in which eco­nomic change con­tin­ued while the cli­mate re­mains un­changed, and vice versa, in or­der to iden­tify which of these fac­tors gen­er­ated wa­ter short­ages.
