Abstract

In the last three decades, important rainy deficits rainfall have characterised the climate trend of the main southern agricultural regions of the Republic of Congo (Vallée du Niari and the Plateau des Cataractes) that represents 95000 km2, 28 % of the Congolese territory. The rainy deficit rainfall is approximately 10 % and had been accompanied by seasonal precipitation disorganisation. Increasingly, the great dry season (of June to September) lengthens, what induced the shortening of the first rainy episode (on the average of October to December) or delays of rain beginning. To the south of Congo, as everywhere elsewhere under humid tropics the agriculture is essentially pluvial and is strongly dependent the seasonal precipitation distribution. Characteristics of precipitation such that the onset, the end and the rainy season length and the total rainfall, as well as the different lengths of sequences dry during the vegetative season have important effect on the plants development. The main goal of this study after having defined beginning and end dates of rains from criteria agroclimate is the analysis of their variability (shortening or lengthening of the agricultural cycle). This instability us pipe to a proposal of adaptation measures of operations cultural and the choice of varieties to long cycle or short cycle. - (BJ)
