Harvesting change: The impact of climate change on Africa’s agriFood systems por Piñeiro, Valeria, Gianatiempo, Juan Pablo, McNamara, Brian, Thomas, Timothy S., Traoré, Fousseini

“…Indeed, the continent emits 7 times less greenhouse gas compared to Europe and 15 times compared to North America (IPCC, 2023). In addition to rising temperatures, climate change affects Africa through several channels, including an increase in ocean levels, variations in precipitations (droughts and heavy rains), plant pests and animal diseases. …”
