Abstract

This work determines the trends for precipitation and temporal drought for Nigeria using a century precipitation records (1916-2016). Accurate prediction of precipitation trend and drought will promote the economic and social activities of a country. The precipitation trend is evaluated using two non-parametric techniques; Mann-Kendall (MK) and Spearman’s Rho (SR) in six stages; monthly, Seasonal, 33 years (1916-1948), 33 years (1949-1981), 35 years (1982-2016) and century records while the drought analysis is carried out using Standardized Precipitation index (SPI) method in the usual condition of one month (SPI-1), three months (SPI-3), six months (SPI-6), nine months (SPI-9) and twelve months (SPI-12). A slight decrease is found in respect of the precipitation trend in monthly, seasonal, 33 years (1916-1948), 33 years (1949-1981) and in the century record while a slight increase in trend is noticed for the 35 year (1981-2006) records of the period studied. In the SPI drought Investigation; extreme drought are observed in 1933 and 2003 for SPI-1, in 1918, 1954 and 1956 for SPI-3, in 1956 for SPI-6, in 2003 for SPI-9 and in 1955, 1957 for SPI-12. Over the century records the trend of precipitation indicate a slight decrease while for drought in SPI-12 a slight increase is observe.
