Highlights

  • Southern provinces were the most affected by the shortage of rain in December 2021.

  • Lowest levels of vegetation cover in the provinces of Benguela, Huambo, Namibe, Huíla and Cunene and the coastal zone of Cuanza Sul.

  • Above average rainfall in northwest Angola and parts of Cuanza Sul, Benguela, Huambo, Huíla and Moxico provinces.

Methodology

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 (dataviz.vam.wfp.org). 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.
