Ethiopia | Desert locust situation report (20 April 2021)
Apr 2021

Key messages:

  • The current upsurge showed signs of significant decline during March as desert locust (dl) swarms continued to decrease in Kenya, Ethiopia and Somalia due to ongoing control operations and poor rainfall.
  • However, good rains have fallen this month in parts of northern Kenya and southern Ethiopia that should allow current swarms to mature and lay eggs. This is likely to give rise to hatching and the formation of hopper bands during May.
  • Compared to one year ago, the scale and extent of the upcoming breeding will be significantly smaller, and the teams, aircraft and other control resources that are currently in place should be able to manage the anticipated breeding.
  • Currently, the majority of the locust infestations in the Horn of Africa are present in Ethiopia where immature swarms persist to the east of the Rift Valley in the Bale Mountains and Harar Highlands. Both these areas have received rainfall that has runoff towards the eastern lowlands where breeding is expected to occur. Immature and mature swarms have recently appeared in some of these areas, primarily in the Somali region from south of Jijiga to Kebri Dehar. Although the situation remains calm further south, a few small swarms may be present in southern Oromia and Southern Nations, Nationalities, and Peoples' Region (SNNP).
  • Even though the situation continues to improve, it is paramount to sustain the current survey and control efforts in reducing existing swarms as well as detecting and controlling any breeding in the coming months. Intense vigilance must be maintained until the autumn.
