Title:The impact of the 1979-85 Sudano-Sahelian drought in Borno, Northeast Nigeria
Author:Kolawole, V.A.
Periodical:Annals of Borno
Geographic term:Northern Nigeria
Abstract:A review of the causes and climatic features of the 1979-1985 Sudano-Sahelian drought and its impact in the Chad Basin area. In terms of rainfall deficiency, river discharges and Lake Chad level, 1983-1985 was the driest period in Borno, northeastern Nigeria, within the period of instrumental record. Lake Chad fell to its lowest level, shrinking to the smallest area ever recorded, leaving stranded all the irrigation projects dependent on it. The severity of the drought is discussed in relation to the Food Availability Decline Index, the Consumer Price Index, and the Behavioural Index. Agricultural and economic losses due to the drought were unprecedented as a result of the commitment to technological sophistication which has impaired the traditional farming pattern and the vulnerability which accompanied its failure. The human impact of the drought has been mediated by the distribution pattern of the rains, the self-help efforts of the people, and the new opportunities provided on the lake floor by Lake Chad recession. The study suggests that the natural environment has become less damaging than the side effects of technological innovation, viz. the South Chad Irrigation Project (SCIP). Bibliogr., notes, ref.
