Biomass production analysis report for 2023 in Niger

31/10/2023
  • Rainy season generally unfavorable to the regeneration of pastoral resources in the Niger
  • Average to deficient biomass production across the majority of the pastoral strip
  • Biomass production is generally in deficit in the Diffa region, in the south-eastern areas of Tillabéri (Abala, Filingué, Ouallam) and north of Tahoua (Tassara, Tillia, Tchinta); in Agadez (Ingal and Aderbissinat); north of Zinder (Tesker and Tanout), north of the Maradi region (Dakoro and Bermo)
  • Exposure to vulnerability of the far north of the pastoral belt of the regions of Tahoua, Zinder, the Diffa region as well as the pastoral areas of Agadez
  • Animal mobility disrupted by insecurity, particularly in the regions of Tillabéri, northern Tahoua, southern Maradi and Diffa, to which are added recurring thefts of herds.
  • Difficult economic context in the face of an agro-pastoral lean season made more difficult by soaring food prices
  • Difficult economic context aggravated by the effects of the series of sanctions following the coup d’état of July 26, 2023

  • Slightly negative biomass production in the center of Hodh El Gharbi in the north of Tagant
  • Biomass production deficit in the northern and eastern parts of Hodh Ech Chargui, Tagant, Inchiri and Nouadhibou
  • Prospects of an early and difficult lean season, particularly in eastern Mauritania

Biomass production analysis report for Mali in 2023

31/10/202331/10/2023
  • Démarrage précoce de la saison des pluies avec une mauvaise répartition dans le temps et l’espace
  • Insufficient biomass production in the northern part of the country
  • Slight deficit in biomass production in the localities of Nara, Kayes and Ménaka
  • Slight surplus of biomass production in the central regions of Mopti and Ségou
  • Increase in security incidents in the regions of Ménaka, Gao, Timbuktu and Mopti
  • Mobility hindered in central and northern regions by armed groups
  • Difficult humanitarian access in the northern part of the country
  • Food and fuel prices soar
  • Imposition of blockades on main roads and continued disruption of economic activities in the northern part of Mali

Biomass production analysis report for 2023 in Burkina Faso

31/10/2023
  • Rainy season generally positive but also marked by floods
  • Biomass production above normal at national level
  • Biomass production above normal across the entire pastoral zone and in the regions hosting transhumant herds: La Boucle du Mouhoun, Cascades, Southwest
  • Difficult security context, particularly in pastoral areas, limiting access to resources and markets
  • Difficult economic context due to the security context limiting the movement of Burkinabé breeders to border countries such as Togo and Benin

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

  • Irregular growth, early stalling and low to very low biomass production in the Lake region (Chad) and eastern Niger
  • Low biomass production in coastal countries, with good production located in Nigeria.
  • End of rainy season expected to be favorable across the Sahel
  • Likelihood of limited vulnerability for breeders

Vegetation stock analysis report for the 2023 dry season in Senegal

16/03/202316/03/2023
  • Vegetation cover in the dry season generally positive across Senegal, result of good biomass production during the 2022 winter season
  • Low vegetation cover in the north and west
  • Very good to good vegetation cover in the center, east and south, particularly the southwest
  • Positive vegetation cover anomalies observed in the center, east, northeast and part of the center-east
  • Negative vegetation cover anomalies located in the departments of Kanel, Ranérou, Tambacounda, Koumpentoum, Koungheul, resulting from bushfires
