ABSTRACT: This study aims to understand the current climatic
trends and explain the possible losses of agricultural yields. To achieve this
objective, this work characterized the evolution of extreme temperature indices
in the sugar complexes of Ferké 1 and Ferké 2, two stations located in the
northern part of C?te d'Ivoire. The onset and cessation dates of the rainy
season and the length of the rainy season were investigated. The agricultural
and climatic data were obtained from each sugar complex. The period of study
ranges from 2002 to 2019 in Ferké 1 and Ferké 2. The results show significant
upward trends in extreme temperature indices. The analysis of sugarcane yield
associated with the different climatic parameters shows no significant results
in general. However, on the Ferkessédougou sugar complexes, the results
highlight that maximum and minimum temperatures could be the variables that
influence most yield production. The maximum temperature with coefficients of
1.60 and 0.77 at Ferké 1 and Ferké 2 respectively seems to contribute to an
increase in yield while the minimum temperature with coefficients of -0.98 and
-0.22 at Ferké 1 and Ferké 2 respectively could lead to a loss in yield. The
results obtained with the Single Linear Regression (SLR) and the Multiple
Linear Regression (MLR) models also highlight the strong influence of minimum
and maximum temperatures.
