A Desert Locust infestation has been ravaging crop and pasture-land, as well as trees and other vegetation since June 2019 in parts of Afar, Amhara, Somali and Tigray regions. The swarms have produced hopper bands that have covered more than 174 square kilometers (in 56 woredas and 1085 kebeles) and are consuming approximately 8,700 metric tons of green vegetation every day...In Afar region, the Desert Locust is spreading to Gewane and Amibara woredas. Over 21,000 hectares (across 15 woredas) was aerially sprayed. (OCHA, 3 Nov 2019)

The Desert Locust (Schistocerca gregaria) infestation in Ethiopia has deteriorated, despite ongoing ground and aerial control operations...Hoppers have fledged, and an increasing number of small immature and mature swarms have continued to devour crop and pasture fields in Tigray, Amhara, Oromia, and Somali regional states. In Amhara, some farms have registered nearly 100 percent loss of teff, a staple crop in Ethiopia. Moreover, eggs are hatching profusely and forming hopper bands in the Somali region, due to the heavy rainfall. The hopper bands recorded to date have covered more than 351 km2 and are consuming at least 1 755 000 MT of green vegetation per day...If not controlled, the Desert Locusts could continue moving within Ethiopia and invade northeast Kenya, the western lowlands and highlands of Eritrea, the Red Sea coastal plains in Eritrea, and adjacent southern coastal areas in Sudan. (FAO, 7 Nov 2019)

Despite major control and prevention operations, substantial crop losses have already occurred in the Amhara and Tigray regions of Ethiopia. The hopper bands -- young locust populations moving together -- have covered nearly 430 square kilometres and have consumed about 1.3 million metric tonnes of vegetation over a two-month period. The formation of bands is ongoing in the rangelands of the Ethiopian Somali Region; and massive new swarms will arrive from Yemen and Somalia. In Eritrea, big swarms of immature adults that migrated from Ethiopia, were identified and controlled around Shieb, Gahtielay, Wengebo and Beareze of the Northern Red Sea Coast. Moreover, the swarms of Tree Locust have been detected in Tserona, Mai-seraw, Quatit and Digsa districts of Southern Eritrea. (FAO, 16 Dec 2019)

The rains have provided favourable conditions for the further breeding of locusts, resulting in total loss of vegetable, fruit and fodder crops, including free-grazing areas. The infestation represents a real threat which could trigger human and animal starvation. The locusts' destruction has impacted Arta, Ali-Sabieh (100 per cent), and Dikhil (As Eyla and Hanle areas) regions, affecting 80 per cent of the total cultivated land. There are reports indicating that the invasion is expanding to the Tadjourah and Obock regions. (OCHA, 16 Dec 2019)

Somalia faces the worst Desert Locust outbreak in over 25 years. Desert Locust breeding is ongoing in Galmudug (Mudug), Puntland and Somaliland. An estimated 70 000 hectares of land have been infested by hoppers and breeding adults, which have already damaged crops and pasture in Ethiopia and Somalia. Over the next six months, more than 100 000 hectares of land will require direct control interventions in Somalia. (FAO, 18 Dec 2019)

The current situation remains extremely serious in the Horn of Africa where, despite control operations, an increasing number of swarms formed in eastern Ethiopia, including the Ogaden, and perhaps adjacent areas of northwest Somalia. Although some swarms moved to Eritrea and Djibouti, the majority moved south in the Ogaden and Somalia, and several large swarms reached Kenya at the end of the month. There is a risk that some swarms could possibly reach South Sudan and Uganda. (FAO, 06 Jan 2020)

The unusually heavy rains that have impacted Eastern Africa since October 2019—driven by the strongest positive Indian Ocean Dipole since 2016—have contributed to a serious and widespread desert locust outbreak, according to FAO and IGAD*. Eritrea, Ethiopia, Kenya, Somalia and Sudan have been affected, with the outbreaks in Ethiopia and Somalia the worst in 25 years, and in Kenya the worst in 75 years. There remains a risk that locusts could appear in south-east South Sudan and north-east Uganda. (OCHA, 17 Jan 2020)

The Government of Djibouti estimates that the damage caused by the Desert Locust infestations on vegetation cover (crops and pastures) have already caused a loss of around USD 5 million for the six regions of the country. (Djibouti Govt/FAO, 03 Feb 2020)

The situation remains extremely alarming in Kenya, Ethiopia and Somalia where widespread Desert Locust infestations and a new generation of breeding threatens food security and livelihoods in the region. The situation is less worrisome in Uganda and Tanzania. (FAO, 17 Feb 2020)

Desert locusts have rapidly spread across the Greater Horn of Africa in the worst infestation in decades. Despite control efforts, eight countries in eastern Africa are now affected (Djibouti, Eritrea, Ethiopia, Kenya, Somalia, South Sudan, Uganda and the United Republic of Tanzania). (FAO, 26 Feb 2020)

Across the ten countries covered by the appeal, over 365 000 ha have been controlled to date, of which an estimated 20 percent was infested by hopper bands and 80 percent by swarms. Thanks to these operations, and based on very preliminary analyses and projections of areas controlled and likely damage caused if not controlled, it is anticipated that 720 000 tonnes of cereal have already been saved, worth around USD 220 million. This is enough to feed almost 5 million people for one year. Through damage averted to rangeland and livestock tropical units, an additional 350 000 pastoral households have been spared from livelihood loss and distress. (FAO, 11 May 2020)

In East Africa, only a few immature swarms remain in northwest Kenya where aerial control operations continue. A small third generation of breeding is likely to commence in October but may be limited by below-normal Short Rains that are predicted for this year. In northeast Ethiopia, numerous hopper bands are present mainly in the Afar region from substantial breeding. Although aerial control operations are in progress, new swarms are likely to form in the coming weeks. In Somalia, aerial control operations using biopesticides are making good progress against immature swarms on the northern plateau in Somaliland and Puntland. Further south, an increasing number of adult groups were reported in the central region of Galguduud in the past week. In Yemen, hopper bands and swarms continue to be present in the interior and are spreading to coastal areas in the south and on the Red Sea. Limited control operations were undertaken in some areas. (FAO, 18 Sep 2020)

Important and widespread breeding continues in eastern Ethiopia and central Somalia where new swarms are expected to start forming in early December and move south to Kenya and southern Somalia by mid-December. Control operations are underway. In Eritrea, immature swarms that arrived from northern Ethiopia have scattered throughout the highlands to nearly the Sudan border. In Sudan, hopper bands and immature adult groups are persisting between the Red Sea Hills and the Atbara River. More immature swarms have been seen in the Tokar Delta on the Red Sea coast in the past few days. In Yemen, summer-bred swarms are still present in parts of the interior. On the 8th, a swarm was seen flying near Bayhan. (FAO, 12 Nov 2020)
