چکیده

This study evaluates how the characteristics of daily rainfall and extreme events in Côte d’Ivoire changed during 1961–2015 using rain gauge observation network National Meteorological Service (SODEXAM). The results indicate that northern southern parts Cote experienced a change from wet to dry period, with cut-offs 1982 1983, respectively. In part, this period was marked by decrease intensity, length spells, contribution heavy rainfall, as well an increase number rainy days spells. Over maximum spells associated 1-day 5-day precipitation events. western part late cut-off 2000; days, intensities, Changes central presented high variability, trends were less marked, even though detected 1991. shows d’Ivoire, which is located subhumid humid region has economy dependent on agriculture (especially cash crops, comprise 60% GDP), experiencing are increasing frequency length. Combined deforestation production, situation could lead desertification compromise sustainable development goals country. found last 15 years, overall risk floods, especially urban areas where city authorities populations not prepared, thereby threatening infrastructure human security.
