| Sorghum,
a drougt resistant cereal, is a very important crop in the drier parts of Mali. |
The
northern half of Mali is nearly all desert, but in the
South there is usually enough rainfall to grow crops.
In between these two areas is a wide belt of semi-desert,
called the Sahel, and the flood plains of the River
Niger. Rainfall here varies and growing food often depends
on the flooding of the River Niger. The best farmland
is in the upper southern part of Mali, where the Niger
and Bani rivers join to form a big area of rich land
where crops grow well. But in many places the rainfall
is not enough, and farmers need irrigation to stop their
crops from dying.
