From the U.N.'s Food and Agriculture Organization, 4 December 2019:
The current situation is extremely serious in the Eastern and Central regions.
Despite intensive control operations, hopper bands and swarms continue to form along both sides of the Indo-Pakistan
border where an unprecedented third generation of breeding started in
November. Some swarms have began their seasonal migration westwards with
a few swarms crossing the Arabian Sea to northern Oman while groups have already appeared in southeast Iran. Swarm migration is likely to continue during December to southwest Pakistan, southern Iran and northern Oman,
and decline thereafter. Countries should remain alert and be prepared.
Subsequent breeding could be delayed in some areas by winter
temperatures.
In the Horn of Africa, swarms have formed in Ethiopia and moved northwards, reaching the Red Sea coast of Eritrea where breeding was underway and at least one swarm crossed the Red Sea to Saudi Arabia. Other swarms in Ethiopia moved east towards the Ogaden, supplemented by additional swarms from adjacent areas of northern Somalia where hopper bands formed. More swarms are expected to form and move to Djibouti, the Ogaden, southern Somalia and perhaps northeast Kenya.....MORE
