Could Africa become the world's bread basket?

PhysOrg article on wheat growing potential of African countries.

answer: Yes, especially in countries with uplands, if they use irrigation in the dry season.

Zimbabwe already does this and is one of the most productive wheat producing countries in Africa.

Not mentioned: If the tsetse fly is controlled, could a lot of those "wildlife parks" be used to grow wheat?

Tanzania report on wheat growing. notes that wheat could be grown in many areas but notes

Tanzania's population is about 20 m and nine tenths of the people depend on agriculture, directly or indirectly, for their livelihood. The inhospitably long dry season, and the infestation of large areas with tsetse fly, restrict two thirds of the population to one tenth of the area of the country.
Zimbabwe is one of the most productive of the wheat-growing nations in Africa, but wheat farmers there are almost entirely dependent on irrigation.

Plos study on Kenya:

tsetse fly not only spread sleeping sickness which kills humans but destroys cattle.

AAT also affects rural sub-Saharan Africa, and the effects of AAT most heavily impact sub-Saharan Africa's poor as 85% of these individuals live in rural areas, with over 80% relying on agriculture for their livelihoods [7]. AAT is responsible for over 3 million cattle and other livestock deaths each year across sub-Saharan Africa [8] with more than 46 million cattle at risk of contracting the disease [9] leading to a considerable impact on the agricultural economy. Direct production losses amount to approximately $1.2 billion each year [10]. Estimates rise to as much as $4.7 billion a year [11] when indirect losses from the inability to use land and livestock to their fullest potential, such as drawing on livestock for traction, are considered. Livestock productivity is necessary if poverty is to be reduced and health improved; livestock provide food (meat and milk), assist in crop production, and provide a source of income for some of the most marginalized rural citizens [12]. Moreover, if nutritional requirements are compromised in populations, morbidity and mortality from other types of infectious diseases increases [13]. Accordingly, AAT is a proximate contributor to poverty, food insecurity, and nutritional deficiencies in rural areas across sub-Saharan Africa.

In three countries in southern Africa—Mozambique, Angola and Zimbabwe—increased wheat production in rain-fed areas may not be feasible, and irrigation would be required to grow wheat in the cool winter months. Zimbabwe is one of the most productive of the wheat-growing nations in Africa, but wheat farmers there are almost entirely dependent on irrigation.

Huh? the IAEA helped eradicate the tsetse fly from southern Ethiopia? (The IAEA is the atomic energy part of the UN).

more HERE.
which says they are only doing the preliminary studies of the habitat with the idea that they will release sterile tse tse flies to cut down the number of flies in these areas.

The Government has selected the Sterile Insect Technique (SIT) to be used as the final component of the eradication because of its non-polluting and environmentally friendly nature.

there are also reports of using old fashioned pesticides in that area.
