Sweet sorghum has multipurpose post-harvest uses. It can produce grains, animal feed and sugary juice, making it unique among crops.
Approximately 22% of Malawians are food insecure, partly because of the poor maize harvest in 2023.
A third of South Africa’s farming income depends on irrigation. Disruptions in power supply put huge chunks of the country’s agricultural fortunes at risk.
Algorithms can help determine what farm inputs and policies can boost food production.
Producers in Zambia should be getting more for their crops, and buyers in East Africa should be paying less, alleviating food price spikes.
Known as ting or amazimba, indigenous sorghum is resilient and rich in cultural and health benefits – yet crops are declining.
If small-scale farmers can’t afford to grow certified seeds – or can’t find them – food shortages would follow.
Rising carbon dioxide in the atmosphere may be a boon for maize crops in tropical growing regions like those found in much of Africa.
Changes in maize production could create complications for Kenya, sub-Saharan Africa’s major importer, because of its policy on genetically modified maize.
Wheat accounts for about 20% of human calorie consumption, and Russia and Ukraine are both major exporters. The war could hit household food supplies in countries as far apart as Egypt and Indonesia.
A historian argues for conservation strategies that embrace creativity and diverse farming methods.
Small and medium-scale farmers and agri-businesses in Southern and Eastern Africa, which are at the heart of inclusive food value chains, are not receiving fair prices for their produce.
Government support for farmers, higher rainfall and grain imports have helped sub-Saharan Africa stave off food insecurity, but the region isn’t out of the woods yet.
For decades Somalia has been in a near-constant state of food insecurity. This is due to a combination of stagnant crop production, a rapidly increasing population and political unrest.
Large-scale droughts can have cascading impacts on food security. They can reduce yield, increase food prices, trigger changes in consumption and lead to unstable supply.
The ex-combatants’ food memories show how they continue trying to make sense of both their past and present experiences of violence.
Low productivity is one of the biggest challenges facing Uganda’s maize industry. But smallholder farmers still won’t adopt improved seed.
Most of the maize consumed in Kenya is never even tested for aflatoxin.
As climate change alters temperature and rainfall patterns, yields of some crops are increasing while others decline. The net result: less food, especially where it’s most needed.
