events are perceived as the visible impacts of climate change.
1 Rainfall and temperature data, provided by the Indian Meteorological Department (IMD) for
Hoskote and Jadigenahalli, has been used in this assessment. The average annual
rainfall data from 1989 to 2013 as also the mean annual temperature data from 1971
to 2013 compiled from the weather reports of the IMD have been analyzed.
Indicator 1: Annual Rainfall
Rainfall variability is a recognized indicator of climate change.
2 The annual rainfall
data from 1989 to 2013 (data from 1996 to 2000 was missing) shows a mean
rainfall of 750 mm and a standard deviation of 238 mm from it (see Fig. 2).
Rainfall and Climate Change: “Farmers occupying mainly rain fed farming
land are more suspected to be prone to Climate change effects like loss of income
and livelihood” (IPCC, 4th Report).
In this region, farmers posses mainly rainfed farming and according to people’s
perceptions there has been a reduced rainfall in the region over the years due to
which lakes and tanks have dried up with a severe scarcity of water being experienced and observed. But this view is not supported by meteorological data
recorded and as the average rainfall pattern in the study area hovers around 750 mm
and the deviation is due to region receiving more than average rainfall in 1993 and
2008 (1200 mm) and a reduced rainfall in 1989, 2002, and 2009 (420, 430, and
560 mm, respectively) as shown in Fig. 3.
People perceived that 30 years ago the rainfall pattern was more than the normal
and tanks filled (1993), but people also observed that despite the years 1993 and
2008 witnessing a fairly high rainfall, the water scarcity continued to persist. The
reason was reduction in the number of lakes/water storage tanks in the region, as
before three decades there were five lakes/water bodies (one in each village) but
