Introduction :
The study area i.e. Ferozepur Jhirka Block is located between latitudes 27° 39' N and 27° 53' N and longitudes 76° 54' E and 77° 9' E. It is situated in the southern-most part of Gurgaon district and Mewat region. Delhi metropolitan city is about 120 kms from the area. Important towns around the area are Alwar, Kaman, Tijara (in Rajasthan), Kosi, Chhata and Ghaziabad (in UP), Hodal, Palwal, Nagina, Nuh, Sohna, Gurgaon, Faridabad and Rewari in Haryana. The total geographical area of the Block is 302.89 km2. Delhi-Alwar National Highway No.8 passes through the Block. It is also a part of the National Capital Region of Delhi. The Block has 81 villages and Ferozepur Jhirka is the only town in the area. Physiographically, the area is characterized by gently sloping hills and undulating plains. Prominent topographical features of the area are elongated rocky ridges running north south on the western border and northeast to southwest on the eastern border. The hillocks on the western side are sloping towards the east and hilltops can be easily seen to rise high above the alluvium. On the eastern side, the hills slope towards the east. There are also some isolated denuded hills in the eastern part of the Block and those also show the general north-south trend of the Aravalli range.
Spatial patterns and variations of different attributes relating to landform, land use, wasteland and demographic characteristics and their spatial association are brought out in the study. Genesis of wasteland and their typologies into degraded forests, undulating land, gullied and ravinous land, degraded pastures, waterlogged, salt-affected and sand-affected areas etc. have been mapped and analyzed with special reference to their relationship to natural environment, other land uses, human response and the problems and potentialities for reclamation.
Qualitative data retrieved from satellite imageries in the form of maps have been quantified and brought to the administrative mode using village boundary to facilitate its effective use in planning. Choropleth maps generated by this exercise have been compared with those based on revenue data compiled from patwari records. The anomalies have been very effectively brought out; and potential use of remote sensing techniques in building up a resource inventory in all its spatial pattern and association with several attributes relating to the resources base illustrated with the help of maps.
Village clusters have been identified based on homogeneity criteria. This is an attempt in regional synthesis based on the spatial patterns of distribution and association of important attributes of land quality and land use analyzed during the study. Pending the application of quantitative techniques of spatial association of attributes and grouping of villages according to similarity in the pattern of association village clusters are identified by map overlay technique. This approach, elementary as it would appear initially, is suitable in micro level planning where all the patterns of distribution reveal realistically the ground reality as implied in hierarchic concept of space and spatial generalization.
