Climate Change and Drought in Kano and Jigawa States, Nigeria
Volume 10, Issue12 (10 - 2024)
Abstract
Emissions of greenhouse gases by human activities have been producing climate change. One of
the manifestations of climate change is an increase in the frequency and intensity of extreme
climate events such as drought. This study assesses the impact of climate change on drought
events inJigawa and Kano states, Nigeria. Objectives of the study include determining the past
and projected (i) drought frequency,and (ii) drought intensity and changes in temperatures in the
study area. Historical (1901-2020) and projected (2021-2100) rainfall and temperature data
(CMIP6– SSP119 and SSP585) for the study area were downloaded from the World Bank
Climate Change Knowledge Portal. The Standardized Precipitation Index characterized the
rainfall conditions by drought and non-drought years.The temperature changes were portrayed
using annual temperature anomaly. The results indicate comparatively wet conditions from the
1900s to the late 1960s, high drought frequency and intensity in the 1970s and 1980s and low
occurrences in the last two decades. SSP119 indicates an increase in drought frequency toward
the middle of the century (2021-2050) and a decrease toward the end. SSP585 indicates the
opposite. Future increases in temperaturesportend an increase in drought intensity. This could be
devastating in the study area because agriculture is the major occupation ofmost of the
population. Therefore, it is capable of disrupting the socioeconomic stability of the states.In this
area, a holistic approach to climate change adaptation should be vigorously pursued anddrought
monitoring should be part of the environmental plan.
