DocumentOther documentLa Production et Protection Intégrées appliquée aux cultures maraîchères en Afrique soudano-sahélienne

No results found.Les légumes sont des produits alimentaires de grande valeur commerciale et nutritifs. Ils peuvent considérablement contribuer à l’amélioration du bien être social et de l’état de santé des populations rurales et urbaines. Leur production en Afrique ne cesse de croître, et en général, il existe encore un grand potentiel pour augmenter la productivité. Cependant, le but n’est pas d’augmenter les rendements par tous les moyens possibles et par l’utilisation massive d’intrants. L’accent doit être mi s sur le développement de systèmes de cultures économiquement rentables, socialement acceptables, durables, respectueux de l’environnement et de la santé des consommateurs. Partout en Afrique, les cultures légumières sont touchées par de nombreux ennemis (insectes, araignées, nématodes, champignons, bactéries, virus,...). Suite à l’apparition de résistances, certaines d’entre eux ont atteint de hauts niveaux d’infestation malgré les contrôles chimiques. Les coûts de traitement deviennent alors p rohibitif car le nombre de traitement augmente, ou il faut faire appel à des produits de plus en plus chers. Parfois des produits de plus en plus toxiques sont utilisés. -
DocumentOther documentLa submersion des sols en bananeraie: une technique naturelle de lutte contre les nématodes phytoparasites
Réseau Africain pour le Développement de l'Horticulture (RADHORT)

No results found.L’inondation des sols constitue l’une des méthodes naturelles de lutte contre les nématodes phytoparasites. Les effets de cette immersion sur les nématodes peuvent être divers : inanition des nématodes, asphyxie par manque total d’oxygène, libération de substances toxiques dégagées dans le sol par la matière organique (acides organiques, sulfures, etc...) quand les conditions de température le permettent. L’efficacité de cette technique sur les nématodes dépend essentiellement de la durée de l’i mmersion. En culture bananière, cette méthode peut être facilement employée dans des zones inondables, telles que les banquettes de rivières ou les plantations installées sur des polders. -

2012Also available in:
No results found.Le glyphosate (Roundup) a été expérimenté en hivernage durant la campagne 1993- 1994 à la Station de Recherches Agronomiques de Baguinéda en comparaison avec l’oxadiazon (Ronstar 25) et le désherbage manuel pour la maîtrise des mauvaises herbes pérennes et annuelles des parcelles maraîchères. Cet essai a pour objectifs de: tester l’efficacité des doses recommandées, déterminer la rémanence desdits produits en hivernage, comparer l’effet du désherbage chimique à celui du désherbage manuel.

Book (stand-alone)Technical bookThe future of food and agriculture - Trends and challenges 2017
Also available in:
No results found.What will be needed to realize the vision of a world free from hunger and malnutrition? After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.
