Climate Status of Tripura: A Tight-Rope Walking

2019

Land use is the human utilization for money, private, recreational, conservational and administrative purposes. The idea of land use is firmly interwoven with human network advancement. Examples of human turn of events and land use have molded the earth legitimately and internationally since ancient occasions. Current improvement designs, along with highlights of the common habitat and the outcomes of past advancement exercises, decide future advancement openings, and furthermore the requirement for rebuilding or upgrade of natural assets. North-east India is the abode of highly endemic flora and fauna preserving the pristine environment with little human interference until recent times. However, for past two decades a drastic change in the land use pattern in the region has been observed which may threaten the fragile ecological balance of the region. Tripura, known as one of the seven sisters, is a bamboo resource and second largest rubber producer in India. Tripura has the highest number of primate species found in any Indian state. However, as compared to its other sisters, the state is economically backward. The land use of the state is undergoing rapid change which is facilitated to a great extent by rapidly increasing population. The present paper deals with the changing land use of Tripura especially in the last two and a half decades. The objective of the study is to analyse the changing land use of the state in general and changes in agricultural and non-agricultural land use in particular based upon the data collected from secondary sources like Statistical Abstract of Tripura, Population Tables of Census 1991, 2001 and 2011 along with the information collected from various government websites.

Tripura is one of the smallest states in the country, located in the North Eastern Region (NER) of India, characterized by mostly hilly areas. In hill slopes, shifting cultivation would have been carried by the native tribes to earn a livelihood, which was intrinsically related to their customs and as a way of life. The cultivation resulted in deforestation and soil erosion while causing an ecological imbalance in the surrounding areas. Considering the environmental fallouts, the state government started shifting cultivators' rehabilitation programmes through plantation crop cultivation in the 1990s. Consequently, the problem of shifting cultivation is reduced to some extent. The current study adopted a perception approach to finding out the change in a local environment. The study reveals that due to plantation crop cultivation, plain land cultivation of rice paddy has drastically decreased; besides, trees and bamboo were difficult to access even in remote villages. The temperature increased while the water level decreased in the canal. Similarly, the numbers of birds and animals were also decreasing significantly.

It is time Indians get concerned about climate change and global warming. Climate change is likely to have tremendously adverse impact on the Indians, as the country is vulnerable to the worst types of climate change induced natural disasters. Not all possible consequences of climate change has been fully understood by the scientific community, but the three main categories of impacts on India are those on agriculture, sea level rise leading to submergence of coastal areas and increased frequency of extreme natural events This paper focuses on climate change which is widely recognized as one of the most important issues of the present century. But awareness of climate changes issues has been less among Indians even if the country is one of the most carbon dioxide emitting countries in the world, which ranks only after China and America. Hence, this paper attempts to assess the perceptions of climate change among the postgraduate students of Tripura and role of mass media in combating climate change. Keywords: perceptions, climate change, mass media, postgraduate students.

The impact of climate change is studied in many aspects in different locations in the country and it is concluded that there is high impact on agriculture compared to any other sector in the country. In the present study, long time (1996-2015) weather variables have been analyzed to trend changes using non-parametric Mann Kendall test in Tripura (2309408‘N latitude, 9109882‘ E longitude), located in the North-Eastern Hill Regions of India, representing agro-climatic zone of Mild Tropical Plain Zone. Significant rise in temperature, confounding rainfall amount, distribution and frequency variability, decline in atmospheric evaporative demand via complementary relationship with relative humidity provides sufficient indication that like other parts of India and the Tripura located at NE Region is also experiencing the regional impact of climate change, though the magnitude of change may not be the same. The Evaporation and Relative humidity effects have been found significant almost al...

The warm and humid tropical climate of Tripura (Hyperthermic) in the Purvachal range manifests a high degree of seasonal variability in rainfall (length of growing period >300 days), which is the main support to rainfed shifting cultivation and horticultural plantations in the hill slopes and extensive rice cultivation along with vegetable integration in the plain areas. The spatiotemporal variability in meteorological parameters

Climate change is basically the global phenomena of temperature rise, glacier melt, and sea level rise. The drastic change in climate has taken place after the start of industrialization in 1750 due to the use of fossil fuels which has thickened the greenhouse layer increasing CO 2 concentration from 280 ppm to 395 ppm. In the last one century (1906-2005), the average surface temperature has risen by 0.74 o C. The regional phenomena such as floods, droughts and cyclones also get influenced and aggravated due to the change in climate. Wetlands take in nearly one-fifth of the annual total anthropogenic carbon emissions. This leads to reduction in alkaline property of wetlands. This leads to eutrophication which leads to loss of Phytoplanktons and Zooplanktons. With the rising sea levels, the wetlands are shrinking in their area. Our study is in the Dheer beel of Chapar in Dhubri district of Assam. The change in the climate in past few decades has shown change in the diversity of the Beel and its ecological degradation. The hydrological characteristic has changed with change in time and climate. The Dheer Beel has lots of ecological effect in an around the Chapar-Salkocha region. The Dheer beel within the past decade has lost its earlier glory of ecological as well as commercial importance. It shows a major loss in area, fish species, forest cover and decrease in the population of migratory birds. Thus, this study shows the degradation of Dheer beel due to climate change and covers various aspects of wetland ecosystem vis-à-vis climate change.

It is rightly spoken “Climate change eclipses the planet earth”. The issue is so predominant now, it gradually restricting our social life, peace and harmony. Number of natural calamities like flood, cyclone, drought, severe heat and cold wave, rising of sea level, melting of snow etc is some of the ready effects directly felt in different parts of the globe. The cause may be many beginning from urbanization to modern life style. But sometimes these may be part of our growth. So there may be trade off or compromise between growth and balance with nature. The study may be a small step towards recognizing the arrival of climate change and its impact on particularly agriculture, as our state largely depends on agriculture based economy. The monthly rainfalls (1901-2010) of total 30 districts from IMD sources are considered for the purpose. The statistics of all the rainfall data are calculated along with its time series plotting. The trend analysis has been done using Kendall rank test...

Climate is a critical factor that determines the habitability of a place. India is a vast country, in terms of population and also in terms of diversity, and any significant change in the climatic conditions will affect country`s physical and social setup. Agriculture, health, biodiversity, natural disasters etc. are the major challenges that the country will have to face in changing climatic regimes. Present paper has analyzed the temperature and rainfall data of past 102 (1911-2012) years to know the climatic changes during the past century. It is observed that while temperature has witnessed a significant rise over almost all the parts of the country, rainfall has a two-tailed trend. The state level analysis reveal that out of total 36 states, half of the number (18) have recorded an increase and rest have witnessed a decline in rainfall. Whatsoever trends are, they indicate that climate is changing (somewhere significantly, somewhere underway), and we need to devise policies in favour of environmental conservation and will have to adopt resource frugal living as has been suggested by the old Hindu scriptures.
