Backward and water-scarce Bundelkhand region also figures in this phase.

Racing against time to reach out to maximum voters, BJP
president Amit Shah, Congress Vice President Rahul Gandhi and SP chief Akhilesh Yadav held parallel roadshows in Allahabad.
Offensive personal jibes dominated the campaign for the phase-IV of the crucial hustings with leaders making personal attacks at each other.
Prime Minister Narendra Modi repeatedly targeted the SP-Congress alliance and the BSP, particularly their leaders Akhilesh Yadav and Mayawati, respectively.
"SCAM stands for SP, Congress, Akhilesh and Mayawati," Modi had said in his election rally in Bundelkhand as he appealed to the voters to get rid of them.
He also came up with an alternative full form for BSP -- "Behenji Sampatti Party"-- to which the party supremo and former UP chief minister retorted instantly, saying the initials of Narendra Damodardas Modi stood for "Negative Dalit Man".
The Prime Minister, in one of the rallies, sought to suggest that the SP government had indulged in discriminatory supply of electricity on the basis of religion.
Amid the verbal free-for-all, Akhilesh also appeared to target Modi by making "donkey" remark while referring to an advertisement of Gujarat government in which megastar Amitabh Bachchan promotes tourism in the state.
Without taking any name, he advised the "biggest Bollywood actor of the century" not to "campaign for the donkeys of Gujarat".
While referring to Modi's mannerisms at election rallies, RJD supremo Lalu Prasad used a derogatory term and said the Prime Minister engaged in "empty talk".
