Le renforcement des capacités est maintenant d’une actualité brûlante en Afrique. Avec d’autres bailleurs de fonds, la banque recherche des moyens appropriés de collaborer avec les gouvernements africains pour les rendre mieux à même de mettre en oeuvre des programmes de développement sur tout le continent. Étant donné le caractère rural de la plupart des économies africaines et la concentration de pauvres dans les zones rurales, il est urgent de renforcer les capacités pour promouvoir le développement agricole.
La consommation de produits certifiés n’est plus l’apanage des pays développés. Au Kenya, les premiers marchés biologiques sont apparus à Nairobi en 2006. Ils sont approvisionnés par des maraîchers, confrontés à une diversité de défis : construire une certification biologique crédible, garantir la fraîcheur des produits et composer avec l’hétérogénéité des attentes des consommateurs. À partir de données d’enquête et du cadre analytique des coûts de transaction, nous analysons l’organisation des marchés de 2006 à 2013.
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.
Controlled Environment Agriculture (CEA) is the production of plants, fish, insects, or animals inside structures such as greenhouses, vertical farms, and growth chambers, in which environmental parameters such as humidity, light, temperature and CO2 can be controlled to create optimal growing conditions.
Le principal défi des systèmes alimentaires africains à l’avenir sera de fournir de la nourriture à une population en croissance rapide dont les régimes alimentaires et les préférences alimentaires évoluent. Alors que la population européenne diminue, les consommateurs exigeant des aliments produits de manière écologiquement et socialement responsable, la population africaine va plus que doubler entre 2020 et 2050, la demande alimentaire augmentant encore plus en raison des changements alimentaires.
The main challenge for African food systems in the future will be to provide food for a rapidly growing population with changing diets and food preferences. Whilst the population of Europe is decreasing, with consumers demanding food that is produced in an environmentally and socially responsible way, Africa’s population will more than double between 2020 and 2050, with food demand increasing even more as a result of dietary changes.
This study examines the influence of an extra-curricular educational program on children's knowledge and cultural valuation of wild food plants, which are an important component of their diets. This program aims to reinforce children's traditional knowledge and values around biological resources in Wayanad, India's Western Ghats, encouraging tribal and non-tribal children to learn from each other and from their own communities. Results show that the educational program has enhanced children's ability to identify selected wild food plants.
In this chapter the authors compute measures of total factor productivity (TFP) growth for developing countries and then contrast TFP growth with technological capital indexes. In developing these indexes, the authors incorporate schooling capital to yield two new indexes: Invention-Innovation Capital and Technology Mastery. They find that TFP performance is strongly related to technological capital and that technological capital is required for TFP and cost reduction growth.
The increasing complexity of technology development and adoption is rapidly changing the effectiveness of scientific and technological policies. Complex technologies are developed and disseminated by networks of agents. The impact of these networks depends on the assets they command, their learning routines, the socio-economic environment in which they operate and their history.
Innovation systems can be defined in a variety of ways: they can be national, regional, sectoral, or technological. They all involve the creation, diffusion, and use of knowledge. Systems consist of components, relationships among these, and their characteristics or attributes. The focus of this paper is on the analytical and methodological issues arising from various system concepts. There are three issues that stand out as problematic. First, what is the appropriate level of analysis for the purpose at hand?
