The start of the rainy season is delayed. Following first rains in the extreme south-west in late April, the weather remained mostly dry until the third dekad of May, when rains progressed northwards in the south-west, allowing land preparation and first plantings to start. Satellite imagery indicates that cloud coverage progressed significantly northwards in the west and the centre during the first dekad of June. It is estimated that only 10 percent of the villages in Dosso department and 7 percent in Tahoua department had done their plantings as of late May. Dry plantings are also underway countrywide.
Seed availability is adequate following 1998 and 1999 bumper crops. During
April, scattered Desert Locusts were seen during surveys carried out in south-eastern
Aïr. Control operations treated 710 ha. Untreated adults may persist in the
limited areas of green vegetation. These could have moved west towards Tamesna
and lay if rainfall occurs.
