PHOTOPERIODIC BIODIVERSITIES UNDER LIGHTPOLLUTION IN INDIA DURING ANTHROPOCENE EPOCH

Air, water and soil pollution have confirmed impact on Air, The air, water and soil pollution have confirmed impact on livings but the influence of light pollution on habitats comfort, nocturnal life forms and loss of panaroma of sky by city dwellers at the cost of diminishing energy resources is yet to be established. The light pollution due to artificial lights can upset both (vitro and vivo) of human, disrupt ecosystem, affect natural circadian cycles of habitats, disorder the reproductivity, photoperiodism and growth metabolism of plants and microorganisms. Proper illumination enhances visibility, productive hours and encourage safety. The light pollution (LP) is caused by excess artificial light of human activities in Anthropocene epoch. There is a long gap between the study of LP parameters and its effect. There is discoordination between its measurement, causes, effects and setting of ameliorative measures. The present work is the analysis of SQM results of NOAA VIIRS/DMSP world atlas map of LP from 1992. LP in India is continuously increasing in almost all the cities and the whole country. It is increasing @ 2.3%/annum in India from 1992 whereas the radiance in Delhi, Calcutta, Chenei, Bengluru, Hyderabad Mumbai and Ahamadabad have increased @102% during 2014 to 2017 considering 2013 is the base year. Radiance of the Chennai city was the highest followed by Mumbai and New Delhi. The artificial, the ratio of natural radiance to artificial radiance have also increased more in Hyderabad, Calcutta and New Delhi cities. The Bortle scaling of the major cities of India are mostly of class 8-9. Since LP is growing as a major problem in the Anthropocene epoch, it is high time to monitor the radiance, artificial pollution and impart appropriate steps to ameliorate the LP. The haze and the smog has become a part to the light pollution.
