Diversification of cropping pattern in Kerala was examined for a period of 10 years from 2000–2009, dividing the entire period into two sub periods as 2000- 2004 and 2005–2009. Diversification indices like Herfindhal index and Simpson index were calculated for different districts of the state, for the two periods separately. Almost all districts except Palakkad showed a reduction in diversification from period I to period II, whereas Palakkad showed a negative shift. He study revealed that Thiruvanathapuram moved more towards the specialization of crops followed by Malappuram and Kasargod as comparing both the periods, whereas Kollam, Wayanad and Palakkad exhibited minor shift in crop diversification.
