The meaning of climate change is a change in global or regional climate patterns and the concept indicates it also the increasing levels of atmospheric carbon dioxide produced by the use of fossil fuels and others thing.
The North Eastern sate Tripura has a tropical climate and receives rainfall during the monsoons. The State is situated between latitudes 22°56' and 24°32' North and longitudes 90°09' and 92°20' East. It has an area of 10,491.69 sq. km. The State is located in the bio-geographic zone of 9B-North- East hills and possesses an extremely rich bio-diversity.
The present analysis has to be focused on the change in annual rain fall pattern and the trend of annual rain fall in the state Tripura. It has also focused on the seasonal impact on rain fall. The trend of temperature and the changing pattern of temperature in case of different seasons have to be considered here to analyze the climate change in the state Tripura. The data provided here on Statistical Abstract 2016 by Directorate of Economics and Statistics Planning (Statistics) Department, Government of Tripura, Agartala has used to make the story. The present story has been published as part of “IHCAP-CMS Media Fellowship Program”.
The data on monthly and yearly quinquennial average rainfall in Tripura from 1995 t0 2015 and the data set on temperature recorded at Agartala Airport from 1995 to 2014 are being considered in order to observe the condition of climate change in Tripura.
In the year 1995 to 2014, the maximum annual temperature recorded as 39.4 degree centigrade and it has observed in the year 2014 where the maximum temperature recorded as 33 degree centigrade in the year 1997. The trend value has observed the increasing trend of annual temperature and it has increased to 37 degree centigrade from 32 degree centigrade. The trend of annual temperature which is increasing year after year and it is not the good direction for future. The precautionary steps are to be taken very shortly by the apex authority with an eye to controlling the trend of increasing temperature.
In case of analysis for seasonal variation, it has found that the trend of temperature is increasing. The maximum temperature trend has observed in two quarter, April to June (quarter -II) and July to September (quarter- III). Although the maximum temperature trend observed 109.18 degree centigrade which is followed during the month on April to June in the year 2014 but the highest temperature trend lies between 97.29 in the first quarter from January to March and 109.18 degree centigrade in the second quarter from April to June.
In case of annual data on rain fall in Tripura has revealed that the annual rainfall is declining where the annual rainfall has recorded as 2745.9 mm in the year 1995 and the annual rain fall has recorded as 2229.7 mm in the year 2015. It is the indicator that the annual rain fall is decreasing which is not good for the state Tripura because the Economic Review of Tripura has revealed that the state Tripura is primarily an agrarian State, with about 42% of the population depending on agriculture and allied activities. However, only about 27% of the land is cultivable, rest being hilly and forested. Rice is the major crop in the State.
“High rainfall and good soil offer considerable scope for land-based economic activities. Creation of irrigation sources and intensive land utilization can give a big boost to development of agriculture and allied activities in the State. Significant area of the State is under fruit and plantation crops”, said the report Economic Review of Tripura, 2017-18 published by Directorate of Economics & Statistics Planning (Statistics) Department Government of Tripura, Agartala.
“For a long period, cultivation in Tripura is nature-dependent and bulk of the land produced only one crop in a year. If there is drought, it is adversely affected agricultural production. Irrigation, use of fertilizers and hybrid seeds are minimal. Population growth in the State is a big challenge to the State’s economy”, said the report of Agriculture Department, Tripura.
The data collected from 1995 to 2015 by the Directorate of Agriculture, Government of Tripura has shown that the trend of annual rainfall declining where the annual rain fall trend as recorded 2633.58 mm in 1995 and the trend of same stack 1909.73 mm in 2015.
“The agricultural productions are fully depending on environment or nature. If there is lack of suitable environment to produce crop, it is very difficult to produce. The climate change is also a factor of agricultural production and there is not any chance to escape it”, said Dr. B.K Kandpal, Joint Director of ICAR, Tripura Centre. The present scenario of Tripura is increasing the trend of temperature and the declining trend of rainfall has observed which may affect the agricultural production in the sate Tripura.
Sudip Mujumder, CEO of Bagma Agree Producers’ Development Trust, guided by NABARD said, “There are good numbers of land in the area of Bagma under Gomati District where farmers are depending on paddy production but the farmers are not able to produce paddy if the rain fall does not occur in the nick of cultivation season. Not only this but also the farmers of Tripura still depend on rainfall for their agricultural activities. So it is very important to save environment to protect the climate change for the benefit of farmers in order to do their agricultural activities.”
