Book (stand-alone)SAHEL WEATHER AND CROP SITUATION REPORT - September 2000 2000
Also available in:
Following generally widespread and abundant precipitation over the main agricultural zones of the Sahel in July, rains remained abundant over the western half of the Sahel in early August, decreased in mid-August but resumed in late August. Rains were particularly abundant during the first dekad of August in Senegal (even causing flooding in several areas), The Gambia and Guinea Bissau, during the second dekad in Mauritania and during the third dekad in Mali. In the centre of the Sahel, precipit ation remained below normal in Burkina Faso, except in the south and west. In Niger, below normal rainfall was registered in late August while in Chad, growing conditions were favourable in the Sudanian zone but unfavourable in the Sahelian zone. Satellite images for the first dekad of September shows that cloud coverage remained over most agricultural zones of the Sahel but that intensity of the rains decreased significantly except in south-western Senegal, Gambia and Chad. Rainfall is notably well below normal in northern and south-eastern Senegal, western Mali and most parts of Niger. Crops are generally developing satisfactorily in the western half of the Sahel region. Reduced rains affected crop development in central and eastern Burkina Faso, most parts of Niger and the Sahelian zone of Chad. Improved rains are needed in these areas to avoid water stress or crop failure. Following good rains in July, pastures have regenerated satisfactorily throughout the pastoral zone s of the Sahel. Grasshopper attacks are reported in Chad, Mali, Mauritania, Niger and Senegal. Small scale Desert Locust breeding is in progress in southern and central Mauritania. Some locusts are probably present and breeding in the Adrar des Iforas of Mali and in Aïr of Niger. -

Following widespread rains in July over most producing areas of Mali, Burkina Faso, Niger and Chad, precipitation was generally regular and well distributed in August, although decreasing during the last dekad of the month, notably in Burkina Faso and western Niger. Precipitation remained also regular over Senegal and The Gambia, thus improving growing conditions following late and reduced rains in July. In Mauritania, decreased rains in late August have been compensated by improved and widespre ad rains in early September. In Cape Verde, good rains were registered on the main islands in mid or late August. In Guinea-Bissau, satellite imagery indicates that abundant and widespread rains covered the entire country in August and early September. The impact, however, of civil strife on farming activities remains unclear. The latest Meteosat satellite image for the first dekad of September indicates that clouds remained present over most producing areas of the Sahel. Precipitation should ha ve decreased in southern Mali and eastern Chad but should have been widespread or even have increased in northern areas of Senegal, Mauritania, Burkina Faso and Niger. Reflecting generally good rainfall since late July, crops are developing satisfactorily in most producing areas of Mauritania, Mali, Burkina Faso, Niger and Chad. Crop prospects improved in Senegal and The Gambia but rains need to last until October to cover the crop growing cycle, following the late start of the rainy season a nd subsequent reduced rains. -
Book (stand-alone)SAHEL WEATHER AND CROP SITUATION - August 1998 1998
Also available in:
The rainy season is now well established in most countries of the Sahel. Following reduced rains in late June, precipitation remained generally widespread in July over most producing areas of Mali, Burkina Faso, Niger and Chad, becoming more abundant and reaching quite northern areas during the last dekad of July. By contrast, precipitation remained limited over Senegal and The Gambia and rains started only in late July in northern Senegal. In Mauritania, sufficient rains after mid-July permitte d plantings in the main producing zones. Rains started in Cape Verde in late July. Rainfall decreased in Guinea-Bissau but remained widespread. The latest Meteosat satellite image for the early days of August indicates that clouds remain present over most producing areas of Burkina Faso, Chad, Mali, Mauritania and Niger where precipitation should remain adequate. By contrast, rains remain more limited over Senegal and The Gambia. Reflecting good rainfall in late July and early August, crop s are generally developing satisfactorily in Mali, Burkina Faso, Niger and Chad. Cereals are emerging satisfactorily in Mauritania. In Senegal and The Gambia, crops are severely affected by reduced precipitation. Many plantings failed and improved rains are urgently needed to avoid extensive crop failure. Grasshoppers are reported in Burkina Faso, Chad, Mali, Niger and Senegal. Grain-eating birds are also present in Mali and Senegal. Limited Desert Locusts activity is reported in Niger. Sm all-scale breeding is expected with the onset of the summer rains in southern Mauritania, northern Mali, Niger and Chad.
