change due to Deforestation, Agricultural practices, Urbanization, Industrialization,
emission of greenhouse gases, etc. In the meantime, formation of low pressure and
depression over central India may be the cause of rainfall decreasing in the central
and central-north part of the study area. Such significant decreasing trend of rainfall
may affect the groundwater level, irrigation pattern and fodder crops in those areas.
However, the highest decreasing trend (−43.63 mm/year) of rainfall obtained from
ITA was observed in Sikkim station in India. While the average rate of decrease of
rainfall obtained from Sen’ slope was −2.17 mm/year and the highest was also
found in India at Imphal station (−37.70 mm/year) under Manipur State.
