Abstract

Knowledge of variations in climate,
changes, and forecasts is critical for improved water
utilization and development in a region. Because the
water reserves of the Kaveri River basin in Manmangalam
Taluk, Karur District, are extremely susceptible
to a shifting climate, the current study utilized
31 years of information on climate data, including
the earth’s surface skin temperature (EST), temperature,
and precipitation, and also analyzed human disturbance
score (HDS) that impacts land use and land
cover shifts. The HDS scores of water bodies are
further graded and categorized into low, middle, and
high impacts by the method (Gernes & Helgen, 2002)
with slight modification. Here is a statistically not significant
but positive correlation between the year and
earth’s skin temperatures (r = .152, N = 27, p > .001).
Temperature and year exhibit a substantial, positive
link (r = .255, N = 27, p > .001) and were statistically
connected. The association between the year and precipitation
was non-significant and positive (r = .064,
N = 27, p > .001). Also, the relationship between years
and human disturbance score levels was shown to
be significantly positive (r = .953, N = 27, p > 001).
HDS values are classified into three types. The minimum
ranges from 34 to 75. The least impacted (LI)
was 7.40% from 1995 to 1997, the most impacted
(MI) was 51.85% from 1997 to 2010, and the most
impacted (HI) is presently 40.74% because nearby
counties gained a substantial number of people following
the economic developments, resulting in an
abrupt shift in its LULC pattern. Also, the purpose
of this investigation is to examine the shifts in LULC
from 2004 to 2022 by using QGIS software. The findings
reveal major shifts, with a constant increase in
urban areas and open/fallow areas and a decline in
cropland and vegetation. Throughout the research
span, the residential area expanded by 15.24% and
open land grew by 3.94%, whereas farming surfaces
were reduced. The reduction of agricultural land for
cultivation and plant cover has significantly contributed
to the growth of built-up areas, while urban
sprawl has replaced foliage, ridges, and farms.
