General Situation during November 2017
Forecast until mid-January 2018

The Desert Locust situation continued to remain calm during November. Only low numbers of solitarious adults were present in western Mauritania, northern Niger, Chad, and on the Red Sea coastal plains in Sudan and Yemen. Smallscale breeding occurred in northwest Mauritania, northern Niger and Chad but locust numbers remained low. During the forecast period, smallscale breeding will occur in winter breeding areas along both sides of the Red Sea, especially in Saudi Arabia where good rains fell in November. Locust numbers will decline in the northern Sahel and scattered adults are likely to persist in northern Niger and in northwest Mauritania where small-scale breeding could occur if rains fall.

Western Region. The situation remained calm during November. Low numbers of solitarious adults were present in parts of western Mauritania and started to appear in the north. Small-scale breeding occurred in a few places of northwest, Mauritania, northern Niger and eastern Chad but locust numbers remained low. No locusts were seen during surveys in Algeria and Morocco. During the forecast period, small-scale breeding could occur if rains fall in northwest Mauritania and Western Sahara. Locust numbers will decline in the northern Sahel while low numbers are likely to persist in parts of northern Mali and Niger.

Central Region. The locust situation remained calm in the region during November. Low numbers of solitarious adults were present in a few places of the winter breeding areas along the Red Sea coast in Sudan and Yemen. During the forecast period, smallscale breeding is expected along both sides of the Red Sea, especially in Saudi Arabia where good rains fell during November and, to a lesser extent, in Sudan, Eritrea and Yemen. Small-scale breeding could also occur on the northwest coastal plains of Somalia if rains fall.

Eastern Region. The locust situation continued to remain calm in the region during November. No locusts were reported and no significant developments are likely during the forecast period.
