To successfully realize the African transformation agenda, governments will have to capitalize on the potential of Africa’s youth. Growing up in an increasingly free and fair continent, the young people of Africa are dynamic, forward-looking and best positioned to find innovative solutions to local chal-lenges through the use of science and technology. To do this, conditions have to be suitable and young people need an environment in which barriers to self-actualization are broken.
In Sub-Sahara Africa, adoption rates of improved crop varieties remain relatively low, which is partly due to farmers’ limited access to information. In smallholder settings, information often spreads through informal networks. Better understanding of such networks could potentially help to spur innovation and farmers’ exposure to new technologies. This study uses survey data from Tanzania to analyze social networks and their role for the spread of information about improved varieties of maize and sorghum.
Food systems in developing countries are transforming, involving a rapid expansion of supermarkets. This supermarket revolution may affect dietary patterns and nutrition, but empirical evidence is scarce. The few existing studies have analyzed implications for food consumers and producers separately. We discuss a more integrated framework that helps to gain a broader understanding. Reviewing recent evidence from Kenya, we show that buying food in supermarkets instead of traditional outlets contributes to overnutrition among adults, while reducing undernutrition among children.
La filière oléicole constitue actuellement un des segments important pour le développement de l’économie en Algérie. Cependant, le secteur est confronté à un double défi : Faiblesse des productions et une faible compétitivité-prix. De par sa situation et ses potentialités naturelles et économiques, l’Algérie doit faire partie des principaux pays méditerranéens, producteurs d’huile d’olive.
The project’s overall objective is to improve the rural population’s resilience to food insecurity by increasing their income through Castor oil plant, Honey, Beans and Goat value chains. GIZ is contributing to the Androy, Anosy and Atsimo- Antsinanana regions’ economic development and aims to integrate mainly vulnerable households in these chains, especially households run by a woman. GIZ has selected high potential sectors and wants to make sure that they can adapt to climate change.
Le système d’innovation est un concept clé pour l’analyse des changements socio-techniques qui renvoie à une structure et à des fonctions qui contribuent à développer et à diffuser l’innovation. Cet article propose une approche originale d’analyse d’un système d’innovation au travers des processus de diffusion spatiale d’un produit agricole : l’anacarde (noix de cajou). Les formes et les vitesses de propagation des vergers d’anacardiers sont analysées et mises au regard de la structure et des fonctions du système d’innovation.
Fidèle à sa tradition d’exploration des principales questions émergentes, Nature & Faune a choisi de consacrer cette édition à l’examen de cette urbanisation rapide et de ses conséquences pour les denrées urbaines et la sécurité alimentaire, mettant en exergue les rôles spécifiques de la gestion et de l’utilisation durables des ressources naturelles dans l’évolution rapide de l’alimentation urbaine et de l’équation nutritionnelle en Afrique.
