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

Biomass production analysis report for 2024 in Burkina Faso

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
  • Difficult security context in pastoral areas, particularly in border areas and transhumance corridors
  • Restrictions on mobility due to the security context
  • Disruption of cross-border transhumance to Benin and Togo

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

Biomass production analysis report for Mali in 2024

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

Biomass production analysis report for 2024 in Mauritania

23/10/202406/12/2024
  • Normal to excess rainfall balance with extreme phenomena
  • Overall positive biomass production in Mauritania
  • Rainfall breaks in pastoral and agropastoral areas
  • Existence of some pockets of biomass production deficit in Hodh El Chargui, Brakna, Trarza and Assaba
  • Flooding in Hodh El Chargui and the southern regions (Gorgol, Guidimakha and Trarza)
  • Exposure to vulnerability in the Wilayas of Tagant, Inchiri and Dakhlet-Nouadhibou

  • 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

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
