dc.description.abstractThe purpose of this study is to present the pattern of rainfall distribution and drought analysis in Borno state. The study was carried out using Geographic Information Systems (GIS) approach and drought indices. Rainfall data from 1998-2017 was used to analyze the drought conditions and the Standard Precipitation Index (SPI) method to compute the drought indices. In order to identify the drought years and the extent of annual rainfall deficit, the annual rainfall departure analysis was applied. Thiessen polygon was used to present the drought severity maps (2000, 2004, 2006, 2009, 2011 and 2013), of the study area where the maximum SPI value occurred in 2011 and 2013. Mild and moderate droughts occur in the central portion of the study area. Severe and extreme droughts were mostly found in the northern and some southern parts of the state.en_US
