Several African countries have been experiencing droughts recently. The results have been massive crop failure, which has lead to a food shortage. The following measures can be taken in drought prone regions:
1.) Plant Drought Resistant Crops: It is an important thing for farmers to find out what grows well locally. Examples of drought-resistant crops are: cassava, finger and pearl millet, amaranth species, sorghum,, potatoes, cassava, moringa, paw paw among others. These all do relatively well, even if there is a drought.
Use soil conservation techniques such as soil mulching. More soil conservation methods here
3.) Plant a variety of Local crops: planting a range of drought-resistant crops, reduces the chances for total loss during drought.
It is also very important to choose local crops. These should be crops, that are familiar, like Cassava, which is readily available, and have been grown locally for generations. These are equal and at times superior to imported crops. Local crops are typically hardy, and they are adapted to the local climate, thus making them very valuable.
