Lack of support for beneficiaries of land reform in South Africa has seen many new farmers fail to live off the land.
South Africa's government makes much of its efforts of putting more land in the hands of the previously disenfranchised black majority. Yet, many beneficiaries continue to wallow in poverty.
Researchers at several institutions are searching for microbial solutions for Africa’s low-performing staple crops.
Microbial-based solutions are perhaps the best-kept secret in agricultural innovation.
Africa has the potential to take the lead in the drive to achieve sustainable agriculture.
Sustainable agriculture in Africa has the ability to act as an example for other regions worldwide. But to do this the approaches and technology taken must be interdisciplinary.
Some farmers are suspicious of technological innovation. But technology can really help them.
It's been proved that prizes can boost cultural innovation. The same is certainly true for innovation in agriculture – which Africa desperately needs.
A woman harvests roses in a greenhouse at a flower farm outside Addis Ababa. Floriculture has boomed in Ethiopia.
Considering all the positive signs Ethiopia might very well be on its way to become Africa's industrial powerhouse.
Food security efforts need to look beyond urban agriculture.

Field trials in Senegal show native shrubs can access deep-soil water and make it available to adjacent crops – a technique that could alleviate drought conditions in marginal lands around the world.
An Ethiopian girl sells barley seeds in northern Tigray. The sub-Saharan Africa seed industry remains largely informal.
The seed industry in sub-Saharan Africa suffers from many challenges. India, which has one of the biggest seed markets in the world, offers some lessons on how these challenges could be overcome.
Can science help the developing world stave off a food crisis?
The challenges of feeding a hungry planet are many. Gene editing crops to be more productive, nutritious or hardy could help, but concerns about GMOs abound.

New research upends the previous theory that tsetse flies – and the disease they carry – were the main reason the spread of livestock domestication in Africa stalled out for a thousand years.
Put innovative farming techniques in the right hands.
Africa will be able to feed itself in the next 15 years. That’s one of the big “bets on the future” that Bill and Melinda Gates have made in their foundation’s latest annual letter. Helped by other breakthroughs…
