Introduction
Africa is a continent facing the risk of drought and desertification for many years.
Climate, geography and human activities in the area have all contributed to this
problem. Droughts are frequent in Africa due to its location near the equator, where
rainfall can be unpredictable. Desertification occurs when land is degraded by
human overuse or abuse, leading to soil erosion and loss of vegetative cover. In this
article, I will explore where the risk of drought and desertification is highest in Africa
and what factors contribute to these risks.
1. Definition of drought and desertification
Drought
Drought is a period of drier than normal conditions. Droughts can last for
days, months or years. Droughts often have a significant impact on the
ecology and agriculture of affected areas and take a toll on local
economies. The annual dry season in the tropics greatly increases the risk
of developing drought and subsequent wildfires. Hot periods can
exacerbate drought conditions by accelerating evaporation of water vapor.
The South African weather service defines a drought as a period of 12
moths when total rain received is below 75% of the average.
Desertification
Desertification is a type of dryland land degradation in which natural
processes or human activities result in loss of biological productivity and
drying of fertile areas. This is an expanse of dry land caused by a variety
of factors, including: B. Land overexploitation due to climate change and
human activities.

desertification in Africa is.
Figure 1: Global vulnerability to droughts and desertification.
This map shows hotspots of drought humanitarian risk based on the interaction between extreme
drought and drought. Significant drought risk with high overall human vulnerability. again, Areas with
severe or extreme drought risk but low human vulnerability and unstable climate. The model
predicts an increase in dry seasons as an indicator of the likelihood of future increases in droughts
dangerous. Note that sub-Saharan Africa has been designated as one of the most vulnerable
regions. In terms of vulnerability to drought and desertification.

(Africa)
This map shows 'drought risk hotspots' based on extreme and critical interactions. Drought hazard
with high overall human vulnerability. It also shows important areas or areas at extreme risk of
drought but with low human vulnerability and where climate models are used. We project an
increase in dry seasons as an indicator of potential future increases in drought risk.
