Angola - Rainy Season Monitoring, April 2022



• Provinces of Namibe, Huila, and western Cunene with less than 80% of average precipitation in March 2022.

• Coastal zone of Benguela and Namibe with vegetation cover much below average.

• Provinces of Huambo, Namibe, Huila, and Cunene with below average vegetation cover since the beginning of the rainy season.


The report analyzes rainfall and vegetation cover trends based on the remote rainfall monitoring and Normalized Difference Vegetation Index (NDVI) available on the World Food Programme's DataViz Platform ( The NDVI is an indicator of vegetation cover; therefore, it can be used to predict agricultural production and grazing conditions as well as to monitor drought. For each geographic region, the precipitation and NDVI data are analyzed by comparing the normal situation values (average values) with the values observed in the present season. The analysis assumes that there is no other phenomenon, such as fires, that could affect vegetation in addition to the climate.
