Analysis of Meteorological Drought in Sokoto State for the Past Four Decades (1970-2009)

Article Preview

Abstract:

Meteorological drought disaster is a serious problem in the Sahelian region of the world. This strongly affects the hydrology of the region and creates severe constraint to agriculture and water management. This paper therefore, examines the rainfall characteristics and the extent of meteorological drought in Sokoto state, Nigeria. Daily rainfall data were obtained for a period of four decades (1970-2009) from Nigerian Meteorological Agency (NIMET) through Sultan Abubakar III International Airport, Sokoto Synoptic Station. Data collected were analysed using statistical techniques. The result of the descriptive statistics varies from year to year and slight increase of mean monthly rainfall was observed. Standardized Precipitation Index (SPI) and Rainfall Anomaly Index (RAI) were used in classifying drought severity into severe, moderate and mild conditions. The result is already anticipated since Sokoto State lies within the Sudano-Sahelian region that generally known to be draught prone. Recommendations were offered based on the outcome of the result.
