Despite tall claims of high growth in agriculture sector,the present plans of the state government envisage irrigating only 50 per cent of the total arable land and the state has a long way to go in realising its full potential of irrigation,according to a top government official. Other states believe we have a good model of water management. But this is the scenario: Of the total 125 lakh hectare irrigable land in the state,only 65 lakh hectares will get water even after completion of the Sardar Sarovar project, said J P Patel,additional secretary,Water Resources Department. He was addressing a workshop on Hydrological Information Need orgnaised by the M S University here on Friday. Patel,who is also chief engineer of Narmada and Kalpasar department,said presently around 50 lakh hectares land get water. Fifteen lakh hectares land is irrigated by 18 major dams,20 lakh by private wells and tubewells and five to 10 lakh by check dams. Four to five lakh hectares get Narmada water, he said. He further said that when it is completed,the Narmada dam would supply water to 18 lakh hectares but even then the total area under irrigation would not exceed to 65 lakh hectares,which is around 52 per cent of the total arable land in the state. The remaining 60 lakh hectares will remain dependent on rain,he added. The chief engineer said though central and south Gujarat together account for only 21 per cent of the states geographical area,they have 75 per cent of the water resources of the state while Saurashtra occupies 35 per cent of the states geographical area but has only 16 per cent of water resources. He said Kutch and north Gujarat also needed water to realise the full potential of agriculture in the state. He said the inter-basing water transportation through Narmada and Mahi-Kadana projects had yielded results,but much remained to be done.
