Abstract :
This study investigated evaluation of
geospatial climatic variation and aridity increase, high
risk zone with annual seasonal variation for a period of
thirty years (30 years) from 1990 to 2020 in Jigawa State.
Climatic data for this work are global data sources, which
include; Tropical Application of Meteorology Satellite
(TAMSAT) and NASA Earth observatory. Temperature
data was acquired from NASA Earth observatory while
precipitation data and evapotranspiration data were
obtained from TAMSAT respectively. The seasonal
variation of Jigawa State was investigated using an excel
spread sheet to compare precipitation and temperature in
the extreme Jigawa north and Jigawa south of the areas
was also analyzed to find a critical environmental factor
in determining the evolution of natural vegetation by
considering the water stress which may occur during
reduction of vegetation cover. Results showed that there
was higher evapotranspiration and temperature but less
precipitation in the northern part of Jigawa state. The
rate of evapotranspiration is also high from 2011 to 2020.
Aridity ranges for the Jigawa state are characterized by
very high aridity and very low aridity. Aridity is very
high in the extreme north of Jigawa, with an aridity value
of 0.20 and a land area of 9,062.7 km2
or 39 percent (%)
land mass; aridity is very low in the extreme south of
Katsina, with a value of 0.40 and a land area of 5,044.5
km2
or 22 percent (%) land mass. There is more
precipitation in southern Jigawa than in the northern
part. On the other way round, the temperature is higher
in northern Jigawa than in the southern part
Keywords :
Climatic variation, aridity increase, TAMSAT, remote sensing and GIS.
