Abstract—Tensift region is known by an arid and semi-arid
climate. The city of Marrakech, experience an important
temporal variability in rainfall and an increasing trend of
temperature during the last five decades. However, the
evolution of rainfall is more contrasted by a downward trend in
Marrakech, it is also distinguished by alarming clues of global
warming, like the number of hot days and heat waves. This
paper evaluates the effect of climate change on Vegetation cover
(evaluated by NDVI) in the Tensift region, Morocco.
Temperature, rainfall data, and vegetation cover were used in
this analysis. The effect of climate change on vegetation was
studied using a linear regression analysis method, to explore the
relationship between vegetation dynamics and climate factors
(the trend of vegetation dynamics for the years between 1973
-2019). Analysis of annual data, for the temperature and
vegetation cover shows a low regression coefficient value of
0.3057 and, rainfall and vegetation cover analysis show
regression coefficient value of 0.7024. Monthly periods analysis
showed that the most important period is the one between
December and May where the regression coefficient value is
0.6568. In more details the period between March and May
shows regression coefficient value of 0.4685, the period between
December and February shows regression coefficient value of
0.434, the period between September and November shows
regression coefficient value of 0.0734. The study reveals that,
rainfall is significantly related with vegetation cover, especially
the period between December and May, more than the
temperature does in Tensift region.
Index Terms—Tensift region, climate change, vegetation dynamic, correlation.
