 Africa's net primary productivity, NPP, has been increasing since 1993, with the exception of two years, 2015 and 2016. This increase is attributed to climate variability, which has led to higher temperatures and more frequent droughts. These conditions have caused a decrease in crop yields, leading to a decrease in NPP. However, the overall trend shows an upward trajectory, indicating that Africa's environment is becoming more resilient to climate variability.
