Abstract
Urban fringe development is resultant of natural increase of population of the city and migration of rural population in search of better living. In the process, some increased population is absorbable in the main city and the rest have to settle in the fringe areas of the city. To monitor fringe area dynamics, Remote Sensing is the best available technique and with it timely information generation is possible. In this paper fringe area development trends have been studied with the help of the aerial photographs and satellite imagery. The total covered study area is in three planning districts (zone) of Jaipur. Maximum development was observed in Jothwara industrial zone.
Introduction
Organized city structure in time frame is going to change its shape due to growth of population. Urban planners/decision makers fix their planning targets’ of growth of city for give time frame but due to lack of monitoring stages of growth and due to pressure of urbanization results in unorganized development in the fringe areas of city. In fringe area development mainly non-urban land transforms into urban land. One of the important reason for fringe development is due to inadequate zoning regulations outside the main city. There is also gap between planned development and population growth which also results into informal development. To check informal development or regularize the informal development and to provide facilities with in the time frame of city structure planners/ decision makers need up-to-data on land use development at regular intervals as per their ‘planning targets’. One of the best method available for collecting dynamic trend of urban development is Remote Sensing. With it timely information generation is possible and spatial growth detection is also possible.
Study Area
Jaipur city is State Capital of Rajasthan and is the 12th Metropolitan city of the country as per 1981 census. Its population in 1981 was 1.01 millions. Being State capital it provides services to entire state. Its growth rate was observed 6% per annum during 1971-81 decade. The total study area covers in three planning districts namely Gandhinagar (Zone D), Jodhwara (Zone H) and Civil Lines (Zone G).
Objective of Study:
To map the landuse/landcover for different base years in order to analyze urban development trends in the fringe area of Jaipur city during the period between 1974-98.
Limitation and Variables Considered
The present analysis is, however, limited to only major land use classes because of the use of different scale data products as cited below:
- Residential/ Commercial Landuse:
- Industrial (mostly large and medium size units).
- Institutional and educational offices.
- Transport nodes and network.
- Public utilities services – (Cultural, Historical monuments and other utilities like water tanks, power hose etc.).
- Land under cultivation.
- Other built tup lands.
