Analysis Report on Biomass Production in 2020 in the Sahel

06/11/202009/01/2024
  • Positive rainy season in the Sahel
  • Surplus of biomass production compared to the normal over almost the entire Sahelian zone
  • Locally negative biomass production in Western Mauritania, in the regions of Tagant, Brakna and Trarza
  • Locally moderately negative biomass production in the Matam region of Senegal
  • Deficits in biomass production quite critical in the Boucle du Mouhoun, Central West, Central Plateau and Central East regions
  • Negative biomass production in isolated enclaves especially in the northern pastoral zone of Barh-El-Gazel, Batha and Ennedi-Est
  • Difficult economic context due to the sanitary measure and associated restrictions following the COVID-19 pandemic
  • Security context severely hindering herd mobility and access to pasture and water resources in the Central Sahel

Dashboard: Pastoral – COVID-19 Surveillance

18/05/202016/02/2024

This dashboard aims to measure the economic impacts of COVID-19 on pastoral populations. This system is based on the already existing systems of ACF and RBM. It allows to give us weekly information about the situation of the pastoral households.

Analysis Report on Sahel Biomass 2018

19/10/201809/01/2024

Highlights:Overall, biomass production in the Sahel for the 2018 season shows a significant improvement compared to the drought in 2017. However, there are still concerning deficit areas in Senegal and Mauritania that require special attention. These areas could potentially experience an early and prolonged dry season. In addition to the biomass deficit, these areas are also experiencing a deficit in surface water. This marks the fifth consecutive year of biomass deficit in the pastoral zones of Senegal and Mauritania.While much of the Sahel is currently experiencing a “good” season, pastoral communities are still recovering from the 2017/2018 drought. Consequently, the impacts of biomass deficits will be amplified as decimated herds struggle to find pasture and water.Elsewhere, there are moderate biomass deficits in Eastern Burkina Faso, Central Mali (Mopti), and certain parts of Tahoua and Tillabery in Niger. Most of these deficit areas are in proximity to surplus areas. If herd mobility is not hindered, herders should be able to find pastures. However, in conflict or banditry-prone areas (such as Mopti or Tahoua), this may be less evident.Despite a significant improvement in conditions since the previous year, pastoral situations should continue to be monitored. Preparations for the dry season in Senegal and Mauritania should be undertaken without delay.

Recommandations:

  • Refer to ACF’s Early Warning Guide on Available Biomass at: tinyurl.com/early-warning
  • Conduct Rapid Assessments in Deficit Areas to Determine Community Needs.
  • Government and Humanitarian Actors: Adjust intervention plans and emergency measures to account for the current lean season at the beginning of the pastoral season in Mauritania and Senegal, potentially including the following interventions:
  • Strengthening public livestock services and pastoral organizations.
  • Distribution of animal feed.
  • Restocking/de-stocking.
  • Veterinary support and livestock vaccination.
  • Cash transfers.

Bulletin on Biomass Production and Surface Water in the Sahel, Mid-Season of the 2018 Rainy Season

07/09/201809/01/2024
  • The 2018 rainy season benefits from generally favorable rainfall across the Sahel, and biomass production follows this overall positive trend.
  • Regions in the central and northern parts of Senegal have experienced a break in precipitation since the end of July, resulting in a deficit in biomass production that impacts the development of pastures and crops. Senegal is in a negative biomass production situation for the 5th consecutive year.
  • The western regions of Mauritania, especially Brakna and Trarza, are experiencing deficits for the second consecutive year. Regions in the central and western parts of Mali (Mopti, Kayes) have a moderate biomass production deficit, which could be compensated by moderately favorable precipitation forecasts for the end of the rainy season.
  • The western regions of Niger (Tahoua) faced a delayed onset of the rainy season, leading to low biomass production early in the season. However, the situation has been improving since the beginning of August, indicating a good vegetation regeneration to reach a normal level.
  • The Eastern region of Burkina Faso records a slight deficit in biomass production, but it has been trending towards a normal production level since mid-July.

Joint Statement: Pastoral lean season 2018

02/12/201709/01/2024

The rainy season of 2017 in the Sahel was unfavorable for vegetation and water. There are currently critical deficits in biomass and water production in Senegal and Mauritania, and these deficits are significant in Mali, Niger, and Chad. Additionally, extreme deficits in surface water pose a threat to pastoral communities. One immediate consequence of these deficits will be an early dry season (usually lasting from May to August), which will be particularly challenging for the poorest populations and the most vulnerable households in the Sahel.
