Sahelian biomass production analysis bulletin at rainy mid-season 2025

26/09/2025
  • Early to normal start of the rainy season in the Sahel; late onset in coastal countries
  • Above-average biomass production across the Sahelian belt
  • Low to very low biomass production in southwestern Mauritania, western Senegal, and the northern edge of the Sahelian belt
  • Weak biomass production in coastal countries, more pronounced in Nigeria
  • River flows above average, causing flooding
  • Favorable end of the rainy season expected across the Sahel
  • Potential vulnerability for herders in areas with low to very low biomass production

Biomass production analysis report in 2024 in northern Côte d’Ivoire

06/12/202406/12/2024
  • Rainy season generally poor in the northern regions, marked by a late start and early end of the rains and some extreme rains leading to flooding in certain localities
  • Biomass production well below normal in northern Côte d’Ivoire, with the lowest annual production recorded in 25 years in some places
  • Deterioration of the security situation in the Sahel leading to an increase in the flow of transhumant herders from Burkina Faso and Mali to the main refugee-hosting departments in the north of Côte d’Ivoire

Analysis report on biomass production in 2024 in the Sahel

31/10/202406/12/2024
  • Significant rainfall received, particularly in the Sahel countries
  • Good biomass production in the Sahelian zone of West Africa overall
  • Biomass production significantly above normal in Central Sahel
  • Average to low biomass production on the western coast and coastal countries
  • Low exposure of the region to vulnerability related to biomass
  • Runoff above normal levels, causing significant flooding
  • Security context severely hindering the mobility of herds and access to pastures and water resources in Central Sahel, in addition to mobility restrictions towards coastal countries, particularly Benin and Togo
  • Significant movements of displaced populations with livestock in several areas of the region

Biomasse

Biomass production analysis report for 2024 in the Sahel

31/10/202406/12/2024
  • Heavy rainfall received particularly in the Sahel countries
  • Good biomass production in the Sahel region of West Africa overall
  • Biomass production much higher than normal in the Central Sahel
  • Average to low biomass production on the western coast and in coastal countries
  • Low exposure of the region to biomass-related vulnerability
  • Higher than normal flows causing significant flooding  
  • Security context severely hampering the mobility of herds and access to pastures and water resources in the Central Sahel, in addition to restrictions on mobility towards coastal countries, particularly towards Benin and Togo
  • Significant movements of displaced populations with livestock in several areas of the region

31/10/202406/12/2024
  • Positive rainy season
  • Flooding in places
  • Biomass production above the national average
  • Production well above normal in the center and north
  • Average to low biomass production in the south-central and southern regions

Biomass production analysis report for Senegal in 2024

31/10/202406/12/2024
  • Abnormal rainy season, alternating with above-average rainfall totals and dry spells in Senegal
  • Deficit biomass production across the whole of Senegal, particularly in transhumant transit and reception sites
  • Vulnerability index is neutral over a large part of the country but has improved compared to the previous year
  • Vulnerability index is positive in certain areas of the pastoral regions of the country (Saint Louis and Louga & Matam)

Biomass production analysis report for 2024 in Chad

29/10/202406/12/2024
  • Normal to excess rainfall across the territory
  • Average to good biomass production across the country
  • Good to very good biomass production in the Sahelian part in the regions of Barh-El-Gazel, Batha and Ouaddaï, Ennedi East and West, Hadjer Lamis, Kanem and Wadi Fira
  • Deficit biomass production recorded in the south of the country in Logone Oriental and Occidentale, a large part of Mayo Kebi East and West, Tandjilé and Mandoule 
  • Prospect of a normal and less difficult pastoral lean season in 2025 for the north, but probably early for the south
  • Complex security context in the far north and west of the country

25/10/202406/12/2024
  • Excess rainfall over most of Mali
  • Normal to late start of the rainy season with poor distribution in time and space
  • Good biomass production in the large northern and central part of the country
  • Normal to significant deficit in biomass production in a large part of the south, center and west of the country
  • Very significant deficit in biomass production in the north of the Goundam and Timbuktu circles
  • Unfavorable security situation for breeders with cattle being kidnapped

Biomass production analysis report for 2024 in Niger

25/10/202406/12/2024
  • Rainy season very favorable to the regeneration and development of pastoral resources on the Niger
  • Surplus biomass production across all pastoral areas
  • Thousands of animals lost in floods caused by heavy rains
  • Animal mobility disrupted by insecurity, particularly in the regions of Tillabéri, northwest Tahoua, south Maradi and Diffa, to which are added recurring animal thefts.
  • Difficult economic context for breeders, faced with a pastoral lean season made harder by soaring food prices
