Adapt­ing to chang­ing rain­fall

Down to Earth - - SCIENCE -

NI N E -Y E A R - L O N G tests on crops in West Asia have shown their re­silience to chang­ing rain­fall pat­terns. For the study, an ecosys­tem rich in plant species was sub­jected to ar­ti­fi­cially low rain­fall—as pre­dicted for the fu­ture—and higher-than-av­er­age rain­fall. But it showed barely mea­sur­able changes in terms of di­ver­sity, com­po­si­tion or biomass. Re­searchers say that the re­silience is due to the huge nat­u­ral vari­a­tion in rain­fall seen in the re­gion. Even a 30 per cent re­duc­tion in rain was within the man­age­able lim­its of the crops. Na­ture Com­mu­ni­ca­tions, Oc­to­ber 6
