Micro-irrigation in Assam (Editorial)

Irrigation is specifically meant for increasing agriculture production. Therefore, any action for development of irrigation which may be a project for either major irrigation or minor irrigation is related to agricultural fields and farmers only. The beneficiaries are well attached with irrigation programme, its scheduling, planning for cropping pattern and activities of water distribution in the irrigation network. A common belief amongst the water users is that when the agricultural fields are devoid of moisture and dried up, irrigation is to be performed so that fields are sufficiently wetted and crops get water in abundance. There may be bumper crop production, which may however be due to some other reasons, not because of adequate amount of irrigation. It is evident that enough irrigation does not guarantee huge crop production, this is otherwise leading to disaster in the endeavour. Micro-irrigation is an attempt which guarantees optimum crop production because of assured amount of water supplied to the crops with safety to environment and with assured income generation. It is a smallscale irrigation covering small land holdings and a small group of beneficiaries with a pursuit of judicious water use. The system has the decentralised implication on utilisation and control of water and cost-effective maintenance of the system. Assam, which has almost 5.0 lakh hectares of arable land, has achieved an irrigated area of only 26 per cent. There is vast scope of irrigation in temporal and spatial considerations. It is sad to say that the State still does not have an identified irrigation network covering all districts, which specified the potentiality of available water and the seasonal requirement of irrigation. Even planning for the growth of multiple crops is not matched with the irrigation programmes. The concerned organisations are still not endowed with pragmatic approach for the cropping pattern and the irrigation scheduling simultaneously for the State. Therefore, it will be somewhat unjustified at this moment to ascertain the probable yearly irrigation demand of the State. As there are huge hectares of land still uncovered by irrigation, it will be fruitful to take up a planned programme so that all the potential areas are brought under assured irrigation within 2 to 3 years. The major irrigation projects of the State, however, are not fulfilling the desired goal. After some years of existence, most of the projects have not been functioning properly or damaged otherwise. The recurring expenditure for water conveyance and distribution have been increasing year after year, and the financial chaos for structural maintenance has aggravated the organisational attitude for a genuine conglomeration. The farmers are also deprived of the benefits. Though there is an initiation from the government side, it is doubted whether the revamping of all those sick major irrigation projects will be a technically and economically viable proposition or not. With Assam having fragmented land holdings, ie, lands having areas ranging from 2 hectares to 10-12 hectares in most cases and small user groups varying from individual to a group of maximum 2-3 members, the demand for irrigation is profusely justified for small areas only and in small quantities. It promoted the idea of inclusion of low-cost irrigation facilities, a
