Agartala, Aug 27, 2012 : Tripura has recorded about 26 to 35 percent deficit rainfall in average all districts of the state barring only Unakoti district during the Monsoon season so far, which appears to be better among northeastern states. But unequal distribution of rain in different locations has affected crop production in the state. Mid-term monsoon review of Indian Council of Agricultural Research, Tripura revealed that state had recorded till July total rainfall of 1047mm which is about 31 percent below the Long Period Average between 1971 and 2011.
A report on rainfall status in the state “Rain 2012-An overview in Tripura” by ICAR, Tripura said among the different districts, Dhalai is having about 50% deficit rain while Unakoti is normal. North Tripura district is having about 20% deficits, which is more or less normal. The rest of the state, West Tripura, Khowai and Sipahijala, Gomati and South Tripura district is having 26 to 35 percent deficit rain.
Referring to review, Joint Director ICAR Tripura Centre Dr M. Datta said that in absence of sufficient rain, extra heat exacerbates drying and that contributed to longer and more intense dry spell this year.
Mentioning the status of monsoon rain in Tripura, joint director Datta said, State normally receives about 1425mm rain during monsoon i.e. June to September which is about 60 percent of yearly rainfall. Out of total monsoon rain, about 60 percent rain occurred during first two month of monsoon i.e. June and July. In 2012, this rainfall is about 22 percent below the normal in first two months. Out of eight districts only three districts, North, Unakoti and South Tripura District recorded normal rainfall i.e. within the range of plus-minus 19 percent of normal rain. In all the other five districts the rain is in deficit.
In the absence of rain, extra heat exacerbates drying and can contribute to longer and more intense drought periods. Climate change in the region is found to be accelerated with large amount of carbon emission and deforestation in Northeast India, said Dr Datta , adding that variation of rainfall in small geographical area was found evident this year.
Meanwhile, ICAR Technical Officer (Agromet Advisory Service) Dhiman Das Choudhury said, a projection of rain fall in different stations considering the normal rain in first two months of the season indicates almost normal rain in every district of the state. Any little deviation will lead to deficit rain in many districts particularly in Gomati, Khowai, Dhalai and Sipahijala, which are considered intensive cropping zone of the district.
Das Choudhury said that the union agriculture secretary had expressed concern saying it would not be possible to achieve 257.44 million tons of food grains production this year. Weak rains that started in June will drive up food prices and erode spending power in a country where more than half the population relies on the rural economy.
He suggested that rainwater harvesting is increasingly being considered as a viable strategy for improving food production in rain fed agriculture, as in the state, the total deficit as recorded is around 32 percent and some of the districts are showing alarming deficit in summer rainfall.
