Study­ing farmer's re­sponse

Down to Earth - - SCIENCE -

AC­TIONS OF in­di­vid­ual farm­ers should be an­a­lysed when modelling pest con­trol strate­gies. Farm­ers cre­ate a co­or­di­nated re­sponse to a pest based on the per­ceived threats and guid­ance from com­mer­cial ad­vis­ers. This co­or­di­nated re­sponse, though un­in­ten­tional, can af­fect en­tire eco­log­i­cal sys­tems. Re­searchers used con­cepts of game the­ory to build a frame­work to un­der­stand feed­back mech­a­nisms be­tween ac­tions of hu­mans and the dy­nam­ics of pest pop­u­la­tions. Un­der­stand­ing farmer de­ci­sions can help man­age the sys­tem bet­ter. PLOS Com­pu­ta­tional Bi­ol­ogy, De­cem­ber 31
