Biomass

Biomass production analysis report for Niger in 2026

28/10/2026
  • Widespread deficit in biomass production following irregular rainfall in Niger
  • The situation is particularly worrying in several pastoral areas, especially in Diffa
  • High risk of early pastoral lean season in 2027
  • Early transhumance observed in deficit areas
  • Persistent security situation limiting access to resources in areas of good production

Biomass

Biomass production analysis report for 2026 in northern Ivory Coast

28/10/202628/10/2026
  • Overall, biomass production was satisfactory and in line with the positive trend for 2025, but production in 2026 was generally lower than in 2025.
  • Persistent biomass production deficits in the departments of M’Bengué and Ouangolodougou.
  • Increased risk of forage deficit at the end of the dry season in the departments of Doropo, Téhini and Minignan due to early peaks in biomass.
  • Enhanced monitoring is required in transhumance areas to anticipate the pastoral lean season.

Biomass

Biomass production analysis report for Mali in 2026

26/10/202626/10/2026
  • Significant biomass production deficit observed in the north and center of the country
  • Normal to slightly above-average biomass production observed in the western regions (Kayes and Kita)
  • Significant decline in biomass production compared to previous years 2024 and 2025
  • Prospect of an early and prolonged pastoral lean season in the future

Biomass production analysis report for Senegal in 2026

26/10/202626/10/2026
  • End-of-season slowdown: nationally, biomass production remains close to the average, but is declining compared to 2025
  • In September, daily biomass productivity was below the average profile in most of the monitored departments.
  • Localized deficits in the starting and transit areas: production is below average in the Ferlo and the river valley (Matam, Ranérou, Kanel, Linguère, Podor) as well as in the peanut basin (Kaffrine, Kaolack).
  • Surplus situation in the south and east: the reception areas of Kédougou, Tambacounda, Kolda and Ziguinchor are recording above average production.
  • Overall vulnerability neutral: the national index is neutral and only the Matam department has a moderate deficit. However, pockets of significant to very significant deficits appear along the Senegal River, north of Matam and east of Podor.

Biomass

Biomass production analysis report for 2026 in the Sahel

17/10/202617/10/2026
  • Rainy season characterized by high rainfall variability and with overall below-average conditions, in a context of a return to El Niño-related climatic patterns.
  • Biomass production was slightly below average across Sahelian and pastoral areas, showing a sharp decline compared with the 2024 and 2025 seasons.
  • Severe biomass deficits were observed in Mauritania, northern Mali, eastern Niger, and across the Lake Chad Basin extending into Sudan.
  • Biomass production remained close to or above average in most Sudanian and coastal zones.
  • Insecurity and mobility restrictions continue to limit access to grazing resources.
  • Risk of livestock concentration and an early pastoral lean season in deficit-affected areas.

Alert note on the situation of biomass production in Mauritania at mid-season 2026

14/10/202614/10/2026
  • Biomass production in mid-season 2026 returns to 85% of the reference average, after two seasons with a large surplus.
  • The agropastoral provinces of the south and southeast, which concentrate the bulk of the national livestock, are the most affected: Guidimakha, Gorgol, Assaba, Hodh Chargui, and Hodh El Gharbi. Brakna (65%) and Tagant (59%) are also of concern.
  • Risk of early reduction of pastures, concentration of herds and tensions around water and fodder resources during the 2026-2027 dry season, particularly in Hodh Chargui.

Biomass production analysis bulletin for the Sahel at mid-season of the 2026 rainy season

24/09/202624/09/2026
  • Late onset of the rainy season and persistent rainfall deficits in the Sahel.
  • Forage production is down compared to the exceptional seasons of 2024 and 2025.
  • Marked biomass deficits in Mauritania, Mali, Niger and Chad, affecting the main pastoral areas.
  • The Sudanese and Gulf of Guinea areas remain generally in surplus.
  • Increased risk of fodder deficit, strain on pastoral resources and early transhumance movements.

Biomass

Biomass production analysis report for Burkina Faso in 2025

30/01/202630/01/2026
  • positive rainy season
  • Positive rainy season with localized flooding
  • Winter arrived late across much of the country, but pockets of drought persist.
  • Biomass production above the national average:
    • Very high production levels in the Centre-North, the Mouhoun Loop, the North and the Sahel
    • Average to low production levels in the Cascades, the Centre and the Central Plateau
    • Very low production in parts of the Central-East and Central-West
  • Difficult security situation at the borders and on transhumance corridors
  • Internal restrictions on mobility and limitations on cross-border transhumance to Benin and Togo

Biomass production analysis report for 2025 in the Sahel

08/12/202508/12/2025
  • Rainfall totals generally normal to above average in Sahel countries but normal to below average in Gulf of Guinea countries
  • Biomass production above average across the Sahelian belt
  • Biomass production low to very low in southwestern Mauritania and western Senegal
  • Biomass production moderate to low in coastal countries, though higher than in 2024
  • Low exposure of the region to vulnerability linked to biomass production
  • River flows normal to above average
  • Security context strongly hindering herd mobility and access to pastures
  • Significant movements of displaced populations with livestock across several areas of the region

Biomass

Biomass production analysis report for Niger in 2025

06/11/202506/11/2025
  • The rainy season is favorable for the development of pastoral resources on the Niger River.
  • Overall biomass production is in excess across all pastoral areas.
  • Animal losses following flooding caused by heavy rainfall
  • Animal mobility is disrupted by insecurity, particularly in the regions of Tillabéri, northwestern Tahoua, southern Maradi and Diffa, compounded by recurring animal thefts.
  • An economic context characterized by falling cereal prices and unfavorable terms of trade for livestock farmers.
