abstract = {Aim of this work is the assessment of the individual and
combined impacts of land use land cover change (LULCC) and
inter-decadal climate variations (CV) on the water and
energy cycles over India, given extensive land use land
cover change over the last decades. In this study, we
quantify the contributions of LULC and CV on changes in the
water and energy cycles over the Indian subcontinent through
a scenario-based approach, with Community Land Model version
4.5 (CLM4.5) model runs from 1981 to 2010. The approach
involves four simulation scenarios: (i) the first scenario
considers no LULCC or CV (LULC is fixed and the atmospheric
forcings for 1981–1990 are repeated in the decades
afterwards); (ii) the second scenario considers only the
impact of CV; (iii) the third scenario considers only the
effect of LULCC by updating the LULC every 10 years; and
(iv) the fourth scenario considers the combined impact of
LULCC and CV. LULCC causes an overall decrease in the
evapotranspiration (ET) and soil moisture (SM) by $0.3 \%$
and $0.1 \%$ respectively (comparing 1991–2010 with
1981–1990), while the net radiation $changes < 1 \%.$
On the other hand, CV caused an increase in the ET, SM and
net radiation $by + 5.4 \%,$ $+1.5 \%$ $and + 1.0 \%$
respectively, in spite of decrease of precipitation of
$6.6 \%.$ The combined effect of LULCC and CV leads to an
increase in the overall ET by $3.8 \%.$ Among the LULC
transitions, deforestation and urbanization are found to be
the major causes for hydrological changes over the decades,
but their impact is much smaller, since CV has a greater
impact on the hydrological cycles over India than LULC. The
in-depth understanding of the distinct contributions of
LULCC and CV on the water and energy cycles in tropical and
subtropical regions can be used for framing future water
resources planning and management policies.},
