Monitoring and Early Warning System in the Sahel

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

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

Biomasse

Analysis report on biomass production in 2022 in the Sahel

04/11/202212/11/2023
  • Very good rainy season in the Sahelian zone of West Africa
  • Above normal biomass production in most of the Sahelian zone
  • Very good biomass production in the western block composed of central and southern Senegal, southern Mauritania, central and southern Mali and Burkina Faso
  • Good biomass production in Chad, except in the south of the country
  • Low to very low production in the Central Sahel, particularly in south-west Niger
  • Below average biomass production in coastal countries, particularly in Nigeria
  • Security context strongly hindering herds mobility and access to pasture and water resources in the Central Sahel, in addition to restrictions on mobility to coastal countries, particularly Benin and Togo

Sahelian biomass production analysis bulletin at rainy mid-season 2022

15/09/202212/11/2023
  • Early start to the rainy season in the Sahel with good rainfall
  • Rainfall breaks observed at the beginning of the season
  • Very good biomass production in central and southern Senegal, central and southern Mali, Burkina Faso, and central Chad
  • Below normal biomass production in northern Senegal, southwestern Mauritania
  • Much below normal biomass production in the tri-border area, particularly in southwestern Niger
  • Below normal biomass production in coastal countries, particularly Benin and Nigeria, and below normal production in Togo and Côte d’Ivoire
  • End of rainy season expected to be favourable across the Sahel

Analysis report on biomass production in 2021 in the Sahel

05/11/202109/01/2024
  • Rainy season globally close to normal in the Sahel
  • Biomass production close to normal in almost all of the Sahelian area
  • Negative biomass production in pastoral areas of Mauritania, in the Tagant, Assaba, Guidimakha and Gorgol regions
  • Strongly negative biomass production in Mauritania and moderately negative in the Timbuktu region of Mali
  • Critical biomass production deficits in Hodh El Chargui and Hodh El Gharbi in Mauritania 
  • Negative biomass production especially in the northern pastoral zone of Niger and Chad
  • Economic environment remains challenging
  • Security context severely hampering herd mobility and access to pasture and water resources in the Central Sahel

Biomass Status in the Sahel at Mid-Season of the 2021 Rainy Season

14/09/202109/01/2024
  • Contrasting rainy season in the Sahel with rainfall breaks in the west and normal to surplus in the central part
  • Normal to surplus biomass production in Niger, Chad, Northern Burkina Faso and Eastern Mali
  • Below normal biomass production over central and Western Mali, central Senegal
  • Much lower than normal biomass production over the whole of Mauritania
  • Much lower than normal biomass production in the coastal countries of Ghana, Togo, Benin and Nigeria
  • Difficult economic context due to restrictions following the COVID pandemic19
  • Security context strongly hampering herd mobility and access to pasture and water resources in the Central Sahel
