    SAHEL WEATHER AND CROP SITUATION - July 1999 1999
    Also available in:

    Rising concerns over reduced precipitation in early or mid-June, particularly in Burkina Faso and Niger have eased with abundant rains over most producing areas of the Sahel since late June. Rains have now started in western Gambia, northern Senegal, southern Mauritania, central and northern Mali, eastern Niger and the Sahelian zone of Chad where plantings have started. Further south, above normal rains benefitted recently planted crops and compensated for the below average rains of early to mid -June. In Guinea Bissau, they helped desalination of swamp rice fields where rice seedlings, now in seedbeds, will be transplanted. In Cape Verde, first rains have been registered in early July. Satellite imagery indicates that during the first dekad of July, precitation remained normal to above normal throughout the Sahel except in the south of Chad. The dry spell of early to mid-June in Burkina Faso and Niger delayed plantings and necessitated replantings in some areas. This might reduce production if rains do not continue late in the season. Grasshoppers are reported in Chad, the Gambia and Niger. Grain-eating birds are reported in Mali and Niger. Control measures are underway. Rodent attacks to crops are also reported in Niger. The Desert Locust situation remained calm during June. Low numbers of adults are expected to appear in the summer breeding areas of the Sahel but no significant developments are expected.

    SAHEL WEATHER AND CROP SITUATION - June 1997 1997
    Also available in:

    Rains started in late March/early April in Burkina Faso and became abundant over the south and centre in late May. The rainy season started in April in the extreme south of Chad, Mali and Niger. First significant rains reached the east of Guinea Bissau and the south-east of Senegal in early May and eastern The Gambia in late May. The last Meteosat sattelite image for the first dekad of June indicates that cloud coverage progressed northwards over the Sahel region, especially in its western parts . Substantial rains have covered most parts of Senegal, The Gambia and western Mali. They also reached southern Mauritania, marking an early start of the rainy season in the western part of the Sahel. Rains decreased somewhat in central Burkina Faso and western Niger but increased in south-western and central Niger and some first rains may have been received in the Sahelian zone of Chad. Land preparation and planting are progressing following the onset of the rains. Dry planting is also under way, notably in Senegal. Seasonably dry conditions prevail in Cape Verde and northern parts of Mali, Niger and Chad. Grasshoppers are reported in Ouaddaï region of Chad. Moderate numbers of solitary Desert Locust adults and perhaps a few small groups will move west across the Red Sea to the interior of Sudan and perhaps continue towards West Africa over Chad and Niger if they find dry conditions en route. Small-scale egg laying could occur with the onset of the rains.

    SAHEL WEATHER AND CROP SITUATION - June 1998 1998
    Also available in:

    Rains started in early April in Burkina Faso and became widespread and abundant over the entire country in late May. The rainy season started in April in the extreme south of Chad, Mali and Niger. First significant rains reached the east of Guinea-Bissau in mid-May and the extreme south-east of Senegal in early June. Elsewhere, in Cape Verde, The Gambia, most parts of Senegal, Mauritania and eastern Niger, seasonably dry conditions continue to prevail. The last Meteosat satellite image for the f irst days of June indicates that cloud coverage progressed northwards over the Sahel region, especially in Mali, Burkina Faso and western Niger. Land preparation and planting are progressing following the onset of the rains. Crops are emerging satisfactorily in Burkina Faso and southern Chad and Mali. Grasshoppers are reported in Burkina Faso and eastern Guinea Bissau. No Desert Locusts were reported recently in the region. Low numbers of adults are expected to appear in the summer bree ding areas of southern Mauritania, and northern Mali and Niger. These will lay eggs with the onset of the seasonal rains. However, the scale of breeding this summer is expected to be very small. African Migratory Locusts hoppers resulting from residual populations following infestations in late 1997 have been reported in Chad, near N'Djamena. Rains started in early April in Burkina Faso and became widespread and abundant over the entire country in late May. The rainy season started in Apri l in the extreme south of Chad, Mali and Niger. First significant rains reached the east of Guinea-Bissau in mid-May and the extreme south-east of Senegal in early June. Elsewhere, in Cape Verde, The Gambia, most parts of Senegal, Mauritania and eastern Niger, seasonably dry conditions continue to prevail. The last Meteosat satellite image for the first days of June indicates that cloud coverage progressed northwards over the Sahel region, especially in Mali, Burkina Faso and western Niger.
