CABI’s Plantwise programme runs local plant clinics in 24 countries across Africa, Asia and Latin America where trained ‘plant doctors’ provide on-the-spot diagnosis and advice for farmers who bring samples to the clinics. A database that records each consultation and shares knowledge across clinics and countries continually builds the ability of the programme to respond to farmers’ needs. The programme embodies key principles of an innovation systems approach.

This paper examines the role of postsecondary agricultural education and training (AET) in sub-Saharan Africa in the context of the region’s agricultural innovation systems. Specifically, the paper looks at how AET in sub-Saharan Africa can contribute to agricultural development by strengthening innovative capacity, or the ability of individuals and organisations to introduce new products and processes that are socially or economically relevant, particularly with respect to smallholder farmers who represent the largest group of agricultural producers in the region.

The Nile Story is one of immense challenges and remarkable achievements for the economic development of the region. It begins in 1999, when the ministers in charge of water affairs in the Nile countries agreed to form the Nile Basin Initiative (NBI). Between 2003 and 2015, the Nile Basin Trust Fund (NBTF) supported and coordinated cooperative work in the region, which has been delivered mainly through the NBI.

The authors surveyed small-scale farmers in the Kenyan Rift Valley province (Narok and Nakuru districts) to describe constraints to, and changes in, livestock production and to assess the extent to which farmers have adopted new technologies promoted by extension services. In the arid areas of southern Narok, farmer's main constraints were drought and disease. Farmers in Nakuru district, situated in the fertile highlands of the Rift Valley, were also affected by disease but also lacked markets and capital.

Humanity is faced with the challenge of ensuring food security for all, while respecting the earth’s ecological boundaries. Organic agriculture makes a valuable contribution here. In Africa, certified organic farming is limited to just 0.2 percent of agricultural land – compared to all other continents, the smallest share worldwide. The potential for expanding organic agriculture is great, because it is economically viable in the long term, preserves human, animal and environmental health and conserves soil resources.
