  • Late start to the rainy season
  • Low biomass production across the coastal countries
  • Above-average biomass production in the eastern Sahelian belt
  • Below-average biomass production in western Mali, Burkina Faso, and central Senegal
  • Above-average runoff causing significant flooding, particularly in the Sahelian zone
  • Expected favourable end to the rainy season across the Sahel
  • Potential vulnerability for herders in the western part of the region

Biomasse

Analysis report on biomass production in 2023 in the Sahel

01/11/202312/11/2023
  • Biomass production globally close to normal in the Sahelian zone of West Africa
  • Biomass production higher than normal in the southwest of Mauritania, extending to the northern border of Senegal and the central Sahel region and in Burkina Faso
  • Very low biomass production in the northern limit of the Sahelian belt
  • Very low biomass production in the Lake Chad basin area
  • Negative biomass production anomalies along the coastal countries, particularly in Benin
  • High vulnerability in the northern border of the Sahel
  • Security issues severely hinder the mobility of herds and access to pastures and water resources in the Central Sahel. This is in addition to mobility restrictions towards the coastal countries, especially Benin and Togo

Biomasse

Sahelian biomass production analysis bulletin at rainy mid-season 2023

22/09/202316/12/2023
  • Rainfall situation ranging from average to good across most of the Sahelian belt
  • Occurrence of rainfall breaks and dry spells observed
  • Biomass production near average levels throughout West Africa and the Sahel
  • Good biomass production in the southern region of Mauritania up to the northern border of Senegal
  • Biomass production ranging from average to above normal in the three-border region, except for the Tillabéri zone in Niger
  • Low to very low biomass production across the entire northern fringe of the Sahel in areas with very low production
  • Irregular growth, early decline, and low to very low biomass production in the Lake Chad region (Chad) and eastern Niger
  • Low biomass production along coastal countries, with some localized good production in Nigeria
  • Favourable end of the rainy season expected across the entire Sahel
  • Probability of limited vulnerability for livestock breeders
