Abstract:

 The knowledge of rainfall variability is necessary for development projects planning related to water which is increasingly rare in semi-arid areas This study aims to map and perform a qualitative and quantitative analysis of the spatial and temporal dynamics of rainfall in the northern part of Ivory Coast on a decadal scale over 1961-2000 period in order to ensure the proper functioning of development projects A GIS was therefore used The results showed the disappearance of isohyets with high rainfall towards West in favor of those with low rainfall which appear in East However, rainfall resumption is reported in the last decade (1991-2000) This rainfall dynamic is consistent with covered surfaces analysis by persistent isohyets and with the preponderance of the low rainfall isohyets class which reached 72% of covered surface in the driest decade (1981-1990) During this drier decade, a significant rainfall deficit of -22462mm was recorded against -16879mm in the last decade 1990-2000 when a relative rainfall recovery is perceived The implementation of development projects must therefore be adapted to spatial and temporal evolution of rainfall.
