now only one lake/water body exits in Govindapura, which dramatically brought
down the water holding capacity in the region and also water recharge capacity.
Along with this there was a decreased moisture content retention capacity of the soil
system and heavy/overexploitation of ground water for agricultural activities.
This shows less awareness among villagers about water usage and conservation
(each farmer, on an average, owns 6 bore wells) in terms of cultivating more crops,
leading to a depletion of ground water levels. Further, de-silting of lakes for brick
making industrial units (there are 500–600 brick making units spread across
Jadigenahalli to Malur) has reduced water storage in lakes which cannot be
attributed to climate change.
Indicator 2: Annual ‘Max’ Temperature
The recent global and Indian temperatures have been considered a standard indicator for assessing climate change (see Foot note 2). The mean ‘Maximum Annual
Temperature’ in Bangalore for the period 2001–2013, as availed from the IMD, was
34 °C (as shown in Figs. 4 and 5).
