Comprehensive development plan for Bangalore city (CDP 2015; RMP) delineates the region to be protected in Bangalore. Valley zones which are essentially flood plain region with wetlands are protected as per this norm. Figure 1 maps the valley zone in Bangalore while Figure 2 identifies the proposed SEZ in Agara Bellandur wetland (valley zone). This region is earmarked for SEZ is identified in CDP for setting up of treatment plant (solid and liquid waste), parks, and other public utilities.

Fig 3 depicts the landscape dynamics during 2000 to 2015 (mapped on temporal Google Earth data – http://earth.google.com). Landscape alterations gained momentum with land acquisition by KIADB (through the project proponents). The remote sensing data of 2009 – 2015 substantiates the unabated construction activities in the valley zone (without proper compliance and gross violations of environmental norms). Table 1 highlights extent of landscape alterations and unauthorized occupation of wetlands (Agara-Bellandur wetland).

Figure 4 gives cadastral map (1904, scale: 1 in 7920) of the region with land uses - drainage network, agriculture land parcels, tank boundaries, etc.Figure 5 gives the region (with land parcels) for the proposed SEZ.

Figure 6 gives the boundary with respective survey numbers of land parcels. Figure 7 is an overlay of figure 6 on the Google earth (http://earth.google.com). This reveals an initiation of construction activities during 2010 – construction of compound walls, filling up of low lying areas with building debris and excavated earth. Figure 8 gives the current spatial extent of construction activities (with compound wall) as on 2015 which is given in Figure 9a and 9b (current boundary and boundary as per KIADB, overlaid on Google earth). This also highlights encroachments of a portion of Rajakaluves and also lake bed. Figure 10a to 10g illustrates changes in the landscape analysed using temporal remote sensing data, which indicates:

  1. landscape alterations in the wetland region (identifies for SEZ  in 2007).
  2. Cement walls were erected along the boundary (Fig 4) in 2010.
  3. Rampant dumping of building debris in rajakaluve, low lying areas of the wetlands and digging work for construction of 3 basement floors.

Table 1 lists the spatial changes during 2007 to 2010, which indicates an encroachment to an extent of 10 acres 14.61 guntas in the region (lake bed 3 acre 30 guntas, Rajakaluves )
