    Abstract Depuis plusieurs millénaires, les populations locales Ouest-Africaines ont entretenu et exploité diverses ressources génétiques qui leurs assurent les principales fonctions vitales. Des légumineuses, des céréales et autres ressources alimentaires ont été domestiquées, cultivées et adaptées aux conditions adverses de l'environnement, pour assurer leur subsistance. Seules détentrices des pratiques endogènes ayant abouti à la domestication de ces ressources, les populations locales collectent, exploitent et renouvellement le potentiel génétique des cultivars locaux dont elles tirent énergies, diverses protéines, vitamines, sels minéraux et médicaments. Parmi toutes ces cultures jalousement entretenues par les agriculteurs, le fonio, (Digitaria spp.) probablement la plus vieille céréale africaine, prend une importance particulière du fait du prestige qu'il procure à l'agriculteur. Aliment essentiellement énergétique, le fonio contient une importante teneur en méthionine qui le valorise par rapport aux autres céréales ordinaires telles que le riz et le maïs. Il contient des suppléments vitaminiques et des minéraux essentiels pour les fonctions métaboliques de l'organisme. Outre ces qualités nutritives, la place occupée par le fonio dans les valeurs culturelles Ouest-africaines conduit certaines populations à le considérer comme la culture du roi. Il est servi aux hôtes de marque et est consommé préférentiellement lors des noces. Cette culture, qui supporte les conditions les plus arides, se trouve concentrée sur des terres marginales peu propices à l'agriculture où la pluviométrie dépasse rarement les 1000 mm. Le fonio est une céréale millénaire, l'une des plus anciennes connues dans la région Ouest Africaine. Son aire d'expansion est assez large. En Afrique, il participe à l'alimentation de plusieurs millions d'hommes notamment dans les zones climatiques guinéenne et guinéosoudanienne recevant 500 à 1000 mm de pluie. Les pays Ouest-Africaines en concertation avec les institutions internationales spécialisées en la ...

    Abstract With its detailed descriptions of the wild and cultivated plant species of tropical Africa that are used for their fibres, this book and CD-ROM provides an invaluable resource for education, extension, industry and research. Fibres may be traded internationally, but many are only used locally – for tying material and clothes, for thatching, packing and filling, and for the production of baskets, mats, wickerwork, brooms and toothbrushes. Rattans are also included in this commodity group. The comprehensive and exhaustively researched text describes 515 primary use fibres in 248 review articles. Treatments of the 75 most important fibres are particularly detailed. The primary use fibres are listed alphabetically and described according to a standard format. This includes plant names, origin, properties, uses and trade. Husbandry and disease control methods are also discussed, while information on genetic resources is provided. Many of the articles are illustrated with a geographic distribution map and a line drawing. The accompanying CD-ROM allows for easy searching through the texts and contains numerous additional photographs.With its detailed descriptions of the wild and cultivated plant species of tropical Africa that are used for their fibres, this book and CD-ROM provides an invaluable resource for education, extension, industry and research.

    Abstract Avec ses descriptions détaillées des espèces de plantes sauvages et cultivées d'Afrique tropicale qui sont utilisées pour leurs fibres, ce livre et ce cédérom constituent une ressource inestimable pour l'éducation, la vulgarisation, l'industrie et la recherche. Les fibres peuvent être commercialisées au niveau international, mais beaucoup ne sont utilisées que localement : comme matériau de liage et pour les vêtements, pour les toits de chaume, à des fins d'emballage et de remplissage, ainsi que pour la fabrication de paniers, de nattes, d'objets de vannerie, de balais et de brosses à dents. Les rotins sont également inclus dans ce groupe de matières premières. Le texte, qui s'appuie sur des recherches complètes et exhaustives, décrit l'utilisation de 515 fibres à usage primaire dans 248 articles de synthèse. Les traitements des 75 fibres les plus importantes y sont particulièrement détaillés. Les fibres à usage primaire sont listées par ordre alphabétique et décrites selon un format standard. Celui-ci précise le nom de la plante, son origine, ses propriétés, ses utilisations et son commerce. Les méthodes de contrôle de culture et de la maladie y sont également abordées, et on y trouve aussi des informations sur les ressources génétiques. La plupart des articles sont illustrés à l'aide d'une carte de répartition géographique et d'un dessin au trait. Le cédérom accompagnateur permet de rechercher facilement les textes et contient de nombreuses photos supplémentaires.Avec ses descriptions détaillées des espèces de plantes sauvages et cultivées d'Afrique tropicale qui sont utilisées pour leurs fibres, ce livre et ce cédérom constituent une ressource inestimable pour l'éducation, la vulgarisation, l'industrie et la recherche.

    Abstract At many occasions, diversification of agriculture has been raised as a way to improve smallholder farmers’ livelihoods. However, information on how local communities would respond to a modification of their production system has rarely been adequately explored. This paper summarizes the response to promotion of traditional vegetable crops in the cultivation and diet systems of rural communities in central Kenya and the rift valley. We used group discussions and structured questionnaires to evaluate a post-intervention situation in which spider plant (Cleome gynandra), African nightshade (Solanum scabrum) and amaranth (Amaranthus cruentus) were promoted for increased production and consumption. At the time of the survey, over 90% of the respondents cultivated at least one of the three vegetable species against 11% before the intervention. The uptake of knowledge on the importance of indigenous vegetables and production techniques has increased. So did the proportion of non-participant farmers between 2006 and 2009 for all three vegetable species. The sizes of vegetable plots were, in general, small (0.041±0.03 ha for nightshade, 0.045±0.03 for spider plant and 0.034±0.05 ha for amaranth). Area allocation for vegetable production varies per region and per gender. However, there were no differences between participants and non-participants for area allocation for any of the species. Amaranth was the most often consumed vegetable, with 87% respondents reportedly consuming it, while spider plant was the least consumed, with 29% of respondents. There were no differences between men and women for the frequency of consumption of all three species. The positive response of farmers to diversification offers a strong background upon which further improvement of African agricultural system can be built.

  9. Article ; Online: Importance and practices of Egusi crops (Citrullus lanatus (Thunb.) Matsum. & Nakai, Cucumeropsis mannii Naudin and Lagenaria siceraria (Molina) Standl. cv. Aklamkpa) in sociolinguistic area in Benin

    Abstract African traditional vegetables are perceived as potentially useful for income generation and food security insurance. However, Egusi crops (Citrullus lanatus subsp. mucosospermus, Cucumeropsis mannii and Lagenaria siceraria cv. ' Aklamkpa ') have been overlooked for relatively long time by research and development organizations while they persist in the farming systems of many regions in West Africa. This paper pinpoints the social importance of Egusi crops and their place in the cropping systems in sociolinguistic groups in Benin. In 2005, a countrywide household survey in Benin on farming systems and cropping practices of Egusi crops across five major sociolinguistic groups show that Egusi is ranked among the top ten crops. This ranking is gender-specific but is not age-specific. Farmers allocated on average 0.74 ha for Egusi production with a significant difference across communities. In the Mahi-fon community in central Benin for instance farm size could reach 5 ha. The most cultivated species is C. lanatus subsp. mucosospermus. However, in the Adja community the farmers' preference is for L. siceraria cv. ' Aklamkpa '. Egusi species are cultivated in plain field or in home gardens, either in monoculture or in association with other crops. C. mannii is mostly intercropped and plays a social and culinary role in Nagot-Yoruba community. Although Egusi is not a specific woman crop, women carry out the post-harvest activities for value adding. Utilizations of Egusi crops are different from one sociolinguistic group to another and could represent a plinth on which a sustainable valuation of Egusi crops could be developed.

    Les légumes traditionnels africains sont considérés comme potentiellement utiles pour contribuer à la sécurité alimentaire et à la génération de revenu au niveau des communautés locales. Cependant, Egusi (Citrullus lanatus subsp. mucosospermus, Cucumeropsis mannii et Lagenaria siceraria cv. ' Aklamkpa ') a rarement fait l'objet de recherche et de promotion alors que sa culture persiste dans ...

    Abstract Semi-Arid Regions (SARs) of West Africa are considered climate change “hotspots” where strong ecological, economic and social impacts converge to make socio-ecological systems particularly vulnerable. While both climatic and non-climatic drivers interact across scales to influence vulnerability, traditionally, this inter-connectedness has received little attention in vulnerability assessments in the region. This study adopted the vulnerability patterns framework, operationalized using the Multidimensional Livelihood Vulnerability approach to include both climatic and nonclimatic stressors to analyze differential household vulnerability in SARs of Mali. Findings showed that while drought was the most mentioned climate-related stressor, households were also exposed to a diversity of environmental and socio-economic stressors, including food scarcity, livestock disease, labour unavailability, crop damage, and erratic rainfall patterns. The typology revealed three vulnerability archetypes differentiated by adaptive capacity and sensitivity. Availability of productive household members, household resource endowments, livelihood diversification and social networks were the main discriminant factors of household adaptive capacity, while challenges relating to food and water security make households more sensitive to stressors. The analysis highlighted the heterogeneity in household vulnerability patterns within and across communities. Failing to account for this heterogeneity in adaptation planning might result in a mismatch between adaptation needs and interventions, and potentially in maladaptation.
