L’édition annuelle de Défis Sud propose un regard sur les agricultures, avec des faits, des chiffres et des prévisions. Face à l’augmentation de la population, au réchauffement climatique et à la perte de ressources naturelles, les solutions proposées pour répondre au défi de la sécurité alimentaire mondiale devraient davantage miser sur l’agriculture familiale et l’agroécologie. En 2018 les agricultures familiales seront encore menacées.
Source majeure d’alimentation pour une grande partie de l’humanité, les céréales étaient au coeur de la crise alimentaire en 2008. Elles sont de nouveau en première ligne. Aujourd’hui, les changements de modes de consommation des pays émergents, ainsi que la demande artificielle en agrocarburants, accentuent les problèmes liés à l’offre de céréales.
This paper documents a positive relationship between maize productivity in western Kenya and women’s empowerment in agriculture, measured using indicators derived from the abbreviated version of the Women’s Empowerment in Agriculture Index. Applying a cross-sectional instrumental-variable regression method to a data set of 707 maize farm households from western Kenya, we find that women’s empowerment in agriculture significantly increases maize productivity.
Farm input subsidies are often criticised on economic and ecological grounds. The promotion of natural resource management (NRM) technologies is widely seen as more sustainable to increase agricultural productivity and food security. Relatively little is known about how input subsidies affect farmers’ decisions to adopt NRM technologies. There are concerns of incompatibility, because NRM technologies are one strategy to reduce the use of external inputs in intensive production systems.
Since the early 1990s, liberalization of the seed market in Tanzania has attracted several foreign companies that now market maize hybrids in the country. In this article, we analyze the impacts of proprietary hybrids on maize yields, production, and household living standards. We build on a recent survey of smallholder maize farmers in two zones of Tanzania. Hybrid adoption rates are 48% and 13% in the North and East, respectively. Average net yield gains of hybrids are 50-60%, and there are also significant profit effects.
