| Abstract: | Urbanization incepts serious challenges of growth and its management. The issues of urbanization manifest in the form of overcrowding,
congestion, insufficient infrastructure, inadequate service provisioning, environmental degradation, pollution etc and affect
the socioeconomic development of the city. Ranchi, the capital of newly formed state of Jharkhand (India) has been witnessing
the same scenario; raising the question of its planning and management of growth to make it more efficient and sustainable.
It hoists the necessity to study the pattern of urbanization and its impact on other landuse/landcover categories in Ranchi
city. In order to assess the urbanization pattern and spatio-temporal dynamics in the study area, the changing pattern of
the three significant patch parameters viz. patch frequency, largest patch size and average patch size of all affected landuse/landcover
categories over a time gradient representing the pre-capital and post-capital formation phases of the Ranchi city have been
analyzed. The two conventional landscape indices viz. Shannon’s diversity Index and Simpson’s diversity index and a newly
developed index ‘Normalized Patch size Range Index’ have been employed in the analyses which not only ascertained the finding
derived but also provided meaningful insights pertaining to the spatio-temporal urban landscape dynamics prevailing in the
Ranchi city. |
