Africa has experienced the greatest impacts of climate change on acute food insecurity and malnutrition ( [[#FAO%20and%20ECA--2018|FAO and ECA, 2018]] ). Adverse climatic conditions exacerbate the impacts of an unstable global economy, conflict and pandemics on food insecurity ( [[#AfDB--2018b|AfDB, 2018b]] ; [[#Food%20Security%20Information%20Network%20(FSIN)--2019|Food Security Information Network (FSIN), 2019]] ; [[#Fore--2020|Fore et al., 2020]] ; see [[IPCC:Wg2:Chapter:Chapter-5|Chapter 5]] [[IPCC:Wg2:Chapter:Chapter-5#5.12.4|Section 5.12.4]] ).

More than 250 million Africans are undernourished, mostly in central and east Africa (FAO et al., 2020), which increases childhood stunting, affects cognition and has trans-generational sequelae ( [[#IFPRI--2016|IFPRI, 2016]] ; UNICEF et al., 2019). Undernutrition is strongly linked with hot climates ( [[#Hagos--2014|Hagos et al., 2014]] ; [[#Tusting--2020|Tusting et al., 2020]] ). In Burkina Faso, low crop yields resulted in around 110 deaths per 10,000 children under 5 years, with 72% of this impact attributable to adverse climate conditions in the growing season ( [[#Belesova--2019|Belesova et al., 2019]] ).

Increasing incidence and expanded distributions of vector-borne livestock diseases (e.g., bluetongue, trypanosomiasis and RVF) in response to changes in rainfall and increasing temperatures, undermine food security, especially among subsistence farmers ( [[#Samy--2016|Samy and Peterson, 2016]] ; [[#Caminade--2019|Caminade et al., 2019]] ). Locust infestations linked with changes in climate ( [[#Salih--2020|Salih et al., 2020]] ) are a major risk for food security in Africa.
