    SAHEL WEATHER AND CROP SITUATION REPORT - September 2001 2001

    Following regular and widespread rains in July over the main producing areas, precipitation was generally well distributed and above normal in August in the east and the centre of the Sahel. Rains became abundant in late August in the centre and south of Burkina Faso, the south and the centre of Chad, the southwest and centre of Mali and the centre of Niger. By contrast, in the western countries, The Gambia, Mauritania and Senegal, rainfall was irregular and below normal up to mid-August. The se cond dekad of August was particularly dry and cumulative rainfall was below last year's level and below normal in these countries. However, rains improved significantly in late August and early September, notably in Guinea Bissau, The Gambia, the south and west of Senegal and Mauritania. The satellite image for the first week of September indicates that substantial rains were received over most producing areas of the Sahel. After significant and widespread rains in early August in all agricultur al islands of Cape Verde, precipitation decreased from the second dekad of August but remained widespread. Harvest prospects are favourable in Burkina Faso, Chad, Guinea Bissau, Mali and Niger reflecting generally good growing conditions since July. In The Gambia, Mauritania and Senegal, crop conditions improved following increasing rains in late August/early September but more rains are needed to allow late plantings to cover their growing cycle. Pastures are developing in all pastor al zones. Infestations of grasshoppers are reported in several zones of Chad, Guinea Bissau, Niger and Senegal. Control measures are being undertaken. The Desert Locust situation remains calm.

    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.

    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.
