Land Transformation and Future Projections of Land Consumption Using High-Resolution Remote Sensing Data for Allahabad, India

Abstract

AbstractIn almost developing countries of the world, the per capita per person ratio of land resource is going to be decreased because of increasing population and the country like India is losing their agricultural dominant identity due to transformation of rural area into urban centers. This paper focuses the results on urban sprawl, landuse change, land transformation and land consumption of Allahabad cit based on Survey of India topographical maps of 1973, IKONOS satellite data of 2009 and 2014. The results show that in 1973, the urban built-up area of city based on SOI topographical map was 4760.09 ha, based on IKONOS satellite imageries of 2009 and 2014, the urban built-up area of the city is 7803.16 ha and 8138.39 ha, respectively. This has increased as 3043.07 ha at an interval of 36 years from 1973–2009 to 2009–2014, growth in urban area observed as 335.23 ha. Agricultural land, orchard/plantation, open space, water bodies, and nala converted into urban land. The trend change between 2009 and 2014 has been observed as remarkable decreased to −22.63% in agricultural land, −30.55% in open space, waterbodies −3.91%, and nala-0.51%, respectively. The Land consumption rate and absorption coefficient between the period from 1973 to 2009 and 2014 is 0.006 ha and 0.007 ha, respectively. During 2009–2014, land consumption rate is observed 0.006 ha, land absorption coefficient is 0.001 ha and land consumption for 2014–2021, estimated as 0.005 ha. The digital database generated for Allahabad city in GIS would be very useful for better landuse planning/sustainable development of cities.KeywordsUrbanizationLand transformationIKONOS satellite dataGIS techniques
