INCREASING OF POPULATION AND ITS IMPACT ON BIO-DIVERSITY (A SHORT ANALYSIS IN THE CONTEXT OF JEHANABAD DISTRICT , “BIHAR”) ABSTRACT DR. VIJAY KUMAR Asst. Prof. Department of Geography D.S.W.E COLLEGE. SOHSARAI, NALANDA The high population of Jehanabad district has affected to bio-diversity. For increasing population the need for food, space and raw materials has resulted in destruction of bio-diversity. During the last twenty years 1991-2011 the population of Jehanabad district increased by 53.63 percent. Net sown area has been increased feed the growing population at the cost of forest and vegetation area decreases. This is the cause of decrease in the amount of rainfall, shrinkage in the shelter for animal. The yield of crop plants per unit area of farmed land can be increased by intensive farming methods, such as the application of chemicals, fertilizers and wide spread use of pesticides. These methods have the advantage of increasing the quantity of food grain can be more produced, but can also have on adverse effect on the bio-diversity. For the service of population the role of transportation sector is very important. Increasing number of vehicles more consumes fossil fuels and produced sulphar dioxide in the atmosphere, which cause acid rain effect less bio-diversity. Untreated sewage is released into rivers this results in decrease in species diversity. Deforestation and pollution is main caused to a decreasing of bio-diversity in the Jehanabad district. Bio-diversity cab be maintained by the conservation of endangered species conservation of wildlife, breeding of captive animals, conservation of grazing land, wet land, major and minor source of water stores.

Key words: shrinkage, fossil fuels, sewage, deforestation
