Author(s): Oshneck Mupepi*
Drought is increasing in severity and frequency in Southern African countries hence there is need to assess its spatial
and temporal patterns for the purpose of easing decision making on resilience building. The paper sought to assess
the spatial and temporal variations of drought in Zimbabwe between 2015 and 2021. TCI, VCI and VHI indices
were used to map drought in this study. ArcMap 10.5, SPSS and Microsoft excel were used for data analysis. The
findings indicated that drought varied from district to district or province to province as well as from year to year
across the study years. Fluctuation were noted as years 2015 and 2016 were drought years when most parts of the
country were affected followed by mild droughts in 2017 and 2018. Years 2019 and 2020 registered severe drought
in most parts of the country whilst year 2021 was mildly affected. Drought freque.. View more»
