Shifting Marathwada’s sugarcane and horticulture crops to drip irrigation, extensive watershed development, correcting regional skew in water use, and a new command area development authority for water resource management were some of the recommendations made by Maharashtra’s high level committee headed by Vijay Kelkar on correcting regional economic imbalances in its 2013 report.
The committee was headed by economist and former finance secretary Vijay Kelkar. If Marathwada’s sugarcane crop were fully drip irrigated, 15 lakh hectares of rainfed crop could get protective irrigation. Their yields would improve along with farm incomes. The committee estimated the cost of subsidizing the transition at Rs 1,480 crore. Marathwada has 2.1 lakh hectare under sugarcane compared to 6.7 lakh hectare in western Maharashtra, the sugar belt. Shifting the region’s horticultural crops on 3.68 lakh hectare to drip irrigation would need Rs 1,067 cr, the committee said.
B B Thombare, President of Western Indian Sugar Mills Association told Mint , ‘It is a misconception that sugar cane needs more water than other crops.’ Sugarcane is a 12-18 month crop. It consumes 15 million litres per hectare over one year. On drip irrigation, the consumption falls to 7.5 million. Flow meters installed by his sugar mill found that cotton and chick pea on drip irrigation consumed 7-8 million litres over a shorter period. Bakshi Ram, Director of Coimbatore-based Sugarcane Breeding Institute of the Indian Council of Agricultural Research (ICAR) said there was no correlation between sugarcane cultivation and the drought in Marathwada, which he attributed to low rainfall. But he misses the point: sugarcane does not cause the drought; it aggravates the impact.
Marathwada is reeling under back-to-back droughts, a 42 percent deficit in rainfall in 2014 followed by a 40 percent reduction in 2015. If pigeonpea or tur grown on 5.24 lakh hectare got two protective irrigations, the productivity of 750 kg/hectare would double, the committee said. Pigeonpea needs very little water but also gets little care from farmers.
If cotton, grown on 11 lakh hectare in the region could be relieved of moisture stress during the months of August to October, yields and incomes would rise. Subsidy on micro irrigation to the extent of 90 percent was ‘desirable’ the committee said for sustainability of cotton production in the rain-fed area.
Though soybean needs little water, it cannot withstand a dry spell of more than fifteen days. The 2015 kharif crop withered because there was practically no rain during the crucial month of July. With sprinkler irrigation, fluctuations in the region’s yields (1,700 kg/hectare on average) could be minimised. Marathwada has 8.3 lakh hectare under soybean.The yield of chickpea or chana (800 kg/hectare) which is grown on 4.40 lakh hectare in the region could double with sprinkler irrigation, the committee said.
An enduring solution to the water crisis in Marathwada and Vidarbha lies in the state’s imbalanced use being corrected. Konkan was the most prodigal: eleven percent of the state’s water irrigated just three percent of its crop area. Western Maharashtra followed with 47 percent and 36 percent respectively. In Vidarbha, 30 percent of crop area claimed 28 percent of water. Marathwada was the most frugal with 31 percent crop area consuming just 14 percent of the state’s water. ‘There is a need to revisit regional water use by providing proportionate share of water to deficit areas,’ the committee said.
The question is, can surplus water from say, Konkan, be moved economically to Marathwada? Though Marathwada uses less water, it is wasteful in another respect. Its canals irrigate 4.13 lakh hectare or 38 percent of 10.79 lakh hectare they are capable of. Canal water is utilised to the extent of 76 percent in the rest of Maharashtra.
For this reason, the committee wanted the fiction of ‘irrigation potential’ to be dispensed with and actual irrigated area to be a measure for calculation of development indicators. Land would be considered as irrigated if it received water supply for at least eight months in a year.
Since Marathwada could not rely on any major irrigation project in the foreseeable future, it should develop watershed in mission mode under a dedicated authority, the committee advised. Watersheds are proven and a technologically sound option for in situ and ex-situ conservation of water, the committee said. Of Marathwada’s 7,690 identified watersheds, 3,293 had been completed but work on 1,177 had not even started when the committee was active.
The committee recommended a New Command Area Development Authority (N-CADA) to manage the release and utilisation of water, maintenance of canals and planning of crops for water use efficiency. The construction and maintenance of dams would remain with the irrigation department.
A Maharashtra Agroengineering Company should be created by merging various schemes and their budgets for implementation of micro-irrigation and mechanization programmes. The committee wanted at least one agriculture college for each taluka and one agriculture polytechnic in a cluster of villages with one lakh population to provide trained people for new agriculture.
It recommended a Maharashtra Council of Agricultural Research on the lines of ICAR with a grant of Rs 500 cr at Aurangabad.Recycling and reuse should be mandated across all non-irrigation uses and users of water, the committee said. In order to reduce seepage and wastage, canal water should be distributed through pipelines.
