The future of food : domestication and commercialization of indigenous food crops in africa over the third decade (2012–2021)
This paper follows the transition from ethnobotany to a deeper scientific understanding of the food and medicinal properties of African agroforestry tree products as inputs into the start of domestication activities. It progresse on to the integration of these indigenous trees as new crops within diversified farming systems for multiple social, economic and environmental benefits. From its advent in the 1990s, the domestication of indigenous food and non-food tree species has become a global programme with a strong African focus. This review of progress in the third decade is restricted to progress in Africa, where multi-disciplinary research on over 59 species has been reported in 759 research papers in 318 science publications by scientists from over 833 research teams in 70 countries around the world (532 in Africa). -

Cette étude a été menée pour évaluer l'adoption de la technologie PICS dans les régions de Dosso, Maradi et Zinder au Niger. Nous avons interrogé 600 ménages sélectionnés dans des villages qui ont bénéficié ou non des activités de vulgarisation du PICS. Un modèle de régression logit a été utilisé pour évaluer la décision des agriculteurs d'adopter la technologie PICS. L'adoption globale des sacs PICS parmi les agriculteurs était de 48,4 %. L'adoption du PICS était de 69,7% à Dosso, 41,3% à Zinder et 31,2% à Maradi. Les agriculteurs qui ont suivi la formation PICS étaient 5 fois plus susceptibles d’adopter la technologie que ceux qui ne l’ont pas fait. -
Adoption and profitability of the Purdue Improved crop storage technology for grain storage in the South-Central regions of Niger
Cowpea is a food security crop and a main source of income for farmers in Niger. However,
postharvest storage remains a major challenge due to insect pest attacks. Since 2008, the Purdue Improved Crop Storage (PICS) bags were disseminated in Niger to reduce storage losses. This study was conducted to assess the adoption of the PICS technology in the Dosso, Maradi, and Zinder regions of Niger. We interviewed 600 households selected from villages that did and did not benefit from PICS extension activities. A logit regression model was used to assess the decision of farmers to adopt the PICS technology. The overall adoption of the PICS bags among farmers was 48.4%. PICS adoption was 69.7% in Dosso, 41.3% in Zinder, and 31.2% in Maradi. Farmers who attended PICS training were 5 times more likely to adopt the technology than those who did not. Variables that affected the adoption of the PICS technology included the region, participation in PICS training, and information source. Beyond cowpea, PICS bags were used to store a variety of crops including Bambara nuts, hibiscus seeds, peanuts, millet, and sorghum. Storing 100 kg of cowpea in a PICS bag generated a cash-flow of $70.38 per respondent and a net return of $21.50.
