Book (stand-alone)SAHEL WEATHER AND CROP SITUATION REPORT - August 2000 2000
Also available in:
Rains have been generally widespread and abundant over the main agricultural zones of the Sahel in July. They have been particularly abundant in early and mid-July over Mali and Niger, in late July/early August over Senegal, The Gambia and southern/western Mauritania, and during the entire month of July in Chad. Precipitation was more limited in Burkina Faso but improved significantly over the western half of the country in early August. Rainfall was abundant in Guinea-Bissau. Significant rains were registered on all the islands of Cape Verde in late July. Flooding was reported following heavy rains in mid July in Niger, in late July/early August in northern Senegal and Mauritania and in early August in northern Burkina Faso. Satellite images for the first dekad of August shows that cloud coverage remains present over all the agricultural zones of the Sahel. Precipitation has been particularly abundant over southern Mali and the Sahelian zone of Chad, but more limited over western and eastern Niger and southern Chad. Following these good rains, plant water needs have generally been covered and crops are developing satisfactorily. Recently planted millet and sorghum crops are emerging satisfactorily in northern Senegal, Mauritania, Niger, northern Burkina Faso, Mali and Chad. Elsewhere, crops are growing normally, except in eastern Burkina Faso where more rains are needed to prevent water stress. -
Book (stand-alone)SAHEL WEATHER AND CROP SITUATION REPORT - June 2000 2000
Also available in:
The rainy season has started in late April or May in southern Burkina Faso, Chad, Guinea Bissau and Mali, in the extreme south-west of Niger and the extreme south-east of Senegal; seasonably dry conditions prevail in the rest of Senegal, Cape Verde, The Gambia and Mauritania. This corresponds to the normal pattern in the Sahel, except for Niger where the onset of the rains is somewhat delayed. Satellite imagery for the first dekad of June shows a decrease in the intensity of the rains in the are as where they had started in Burkina Faso and Niger but a significant northwards movement of cloud coverage, indicating that rains progressed over the centre of Mali, Niger and Chad. Land preparation and plantings are in progress following the onset of the rains. Dry planting is also underway in Mauritania and Niger. Crops are emerging satisfactorily in southern Burkina Faso, Chad and Mali but improved rains are needed in the coming weeks . Seed availibility is generally adequate following above average to record harvests in most Sahelian countries in 1009. The pest situation is calm. A few Desert Locusts were reported in mid-April in south-eastern Aïr in Niger and during May in Adrar in Mauritania. Low numbers of adults are likely to appear in southern Mauritania and lay with the onset of the rains. -
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.
