Population dynamics of Indian Himalaya using geographic information systemAuthor(s): Imran A.Dar, Mithas A.Dar
An attempt has been made in this research paper to study the population distribution in the Indian Himalayan region through the integration of Collateral data with Geographic information System (GIS). Such attempt provides a mechanism by which population estimates can be updated with high accuracy and better rate of frequency. For the present study the Toposheets (1: 50000 scale), Boundarymaps and other collateral data, viz., time-series data of decadal growth rate, population distribution pattern, sex ratio, and literacy rate etc. has been compiled fromprevious primary census abstracts and provisional report of 2001census and presented in Rasterized formusingGI in order to depict the EffectiveDynamics of population change in the study area. Geographical information systemwere used for modeling the relationship among population variables and show results obtained empirical model analyses results of this study show that the Nagaland recorded the highest (64.41%) decadal growth rate whereas neighboring Tripura recorded the lowest (15.74%) decadal growth rate in the region. The growth rates of the most of the districts fall above the average growth rate of the region. A negative growth rate (-3.5%) has also been recorded in WestAizwal (Mamit) district ofMizoram. In contrast,Wokha in Nagaland recorded the highest growth rate (95.01%). In India this is very true that growth rate of human population has decreased significantly in the states with higher literacy rates. The overall density of the study area is consistent with location theories, i.e., decline in population density fromthe Central BusinessDistrict (CBD).
