L’intégration des marchés est un élément clé pour comprendre la transmission des prix entre les marchés et maîtriser les équilibres (les efficiences). Cependant, certains facteurs peuvent entraver l’atteinte de cette efficience. C’est ainsi que cet article a pour objectif d’évaluer l’influence des intermédiaires sur l’intégration spatiale des marchés de manioc au Cameroun. Un modèle autorégressif à retards échelonnés (ARDL) y est utilisé pour analyser l’existence des relations de long terme et de court terme entre les marchés. Cette étude aboutit à la conclusion d’une cointégration entre les variables, et fournit la preuve que les marchés sont intégrés. Les résultats empiriques révèlent qu’à long terme, la présence des intermédiaires réduit les prix offerts sur les marchés de Yaoundé ; et à court terme, 95% des déviations du prix sont corrigées dans un délai d’un an et neuf mois. Cette étude préconise donc une normalisation et un encadrement de la fonction d’intermédiaire, afin d’éviter le système des monopoles de marché.

En partant du postulat que le financement agricole contribue de manière significative à la production agricole, cet article analyse les liens entre ressources mobilisées pour le secteur et la sécurité alimentaire au Sénégal. La méthodologie s’appuie sur un modèle de régression multiple, à partir des travaux de Kpodar (2006). Les résultats montrent que toutes les variables, à l’exception du crédit des IMF, impactent significativement la prévalence de la sous-alimentation. Leur hausse permet de réduire l’insécurité alimentaire. L’élasticité de la valeur ajoutée non agricole est plus importante (-4,08) suivie de celle de la démographie (-3,04). L’élasticité de la valeur ajoutée agricole affiche -1,46 et celle du financement -0,43. Quatre implications de politiques économiques sont formulées : renforcer et diversifier le financement agricole, favoriser le développement des marchés alimentaires, accompagner la transformation par l’industrialisation légère et mettre en place une ossature institutionnelle capable de promouvoir la production agricole, au Sénégal.

There is a significant soybean yield gap in sub-Saharan African (SSA) countries. Sustainable intensification of the agricultural sector to reduce such a yield gap is important. Increasing soybean productivity can meet the growing demand for food and feed when complemented with higher soy meal demand by the local livestock industry. This study performs an ex-ante economic analysis to determine the effect of higher soybean production on trade and land use within SSA countries. We find that increasing soybean yield by 50% can increase the total returns from soybean production by 186 million LC (local currency) in Ethiopia and 36 billion LC in Nigeria. We show that soybean yield growth alone is enough to boost soy oil production, as the crushing of the beans produces 18% oil and 79% meal. While increasing productivity may lead to freeing land to produce high-valued cash crops, investors will be reluctant to invest in the crushing facilities in the absence of soy meal demand by the livestock industry. Therefore, policymakers need to establish collaboration between development organisations, private companies, farmers and researchers to achieve this transformation and thereby raise agricultural productivity.

This study analyses the trade-offs between welfare (measured by income) and greenhouse gas (GHG) emissions using a farm-level optimisation model that incorporates the predominant cereal (sorghum), legumes (groundnut, soybeans), livestock (cattle, goats and sheep) and trees (locust bean, camel’s foot) representative of production systems at two contrasting sites in northern Nigeria. The optimisation model maximises the value of total farm production, subject to constraints on GHG reductions of 10%, 25% and the maximum reductions that allow households to meet minimum consumption requirements. Substantive reductions in livestock and legume production would be required to achieve the maximum possible reductions from current emissions and would reduce household income by 22% and 44%, respectively. Under current production practices, reductions in GHG emissions reduce household income, which suggests the need for further research on productivity-enhancing technologies that could both enhance income and reduce GHG emissions in these production contexts.

Fair trade is an important ethical concern in the food value chains of developed countries. However, there is a dearth of empirical insights into consumer preferences for this critical aspect in the domestic markets of developing countries. The current study analysed consumer willingness to pay (WTP) for fair-trade attributes in the goat meat value chain in Nairobi, Kenya. Choice experiment data from 270 randomly sampled consumers was analysed using the random parameter logit (RPL) model. The results show that 56% of the consumers were aware of the fair-trade concept and 64% of them were willing to pay for fair-trade-compliant practices. Specifically, consumers were willing to pay a premium of 62% to prevent child labour, 45% to support provision of medical insurance for workers in the meat value chain, 40% for direct purchase from producers, 39% for fair-trade labelling and 30% to support disabled people as part of corporate social responsibility

Baobab products provide cash income and supplement diets for local communities living in marginalised, arid and semi-arid regions. However, these products are neglected by research, selectively traded and considered underutilised. This study endeavours to narrow this information gap by analysing the determinants of baobab collectors’ choice of marketing channels in Kenya. A multinomial logit was employed, using a dataset of 268 baobab collectors from three counties. The results show that the majority of baobab collectors sell their baobab pulp through rural markets (assemblers and rural wholesalers), as opposed to urban buyers (urban wholesalers, retailers and processors). Export channels are conspicuously missing from the chain. Human capital and transactional and institutional factors significantly influence the collectors’ choice of marketing channels. The results reveal that building capacity around market development, research and education, road networks and institutional services is essential to create more profitable channels for generating income, enhancing food security and reducing malnutrition.

Nutrition knowledge is an important driver of household dietary diversity that can be improved through access to nutrition information. However, in many rural areas, the formal flow of nutrition information is limited, although social networks could play an important role as an informal source of such information. This paper evaluates the effect of nutrition information networks on household dietary diversity in Nyamira and Kisii counties in Kenya. The paper employs a Poisson regression model on a sample of 462 farmers selected using a multi-stage sampling technique. The results show that the average household dietary diversity of an individual’s network (a proxy for social networks) had a positive and significant effect on the dietary diversity of the individual, implying that social networks have a positive effect on household dietary diversity. Moreover, the average education of an individual’s network, along with household size, wealth status and farm size, had positive significant effects on household dietary diversity. These results imply that farmers’ social networks could be used as a complementary tool for the effective delivery of nutrition education targeting the enhancement of nutritional quality.

Smallholder farmers face considerable risk and uncertainty, particularly when markets are incomplete or missing. We consider household crop diversity and crop choice in Zimbabwe, where output markets are largely absent and price signals are inaccurate. In this setting, considering preferences and tastes provides a deeper understanding of how households ensure food security in environments without robust markets. We use data that straddles the period of hyperinflation in Zimbabwe and the collapse of the country’s currency to study household cropping behaviour in a time of extreme stress. This allows us to better understand the relationship between market failure and crop choice in Sub-Saharan Africa.

La production du riz sous contrat a pour avantage de répondre aux exigences de la qualité de la production du riz et de satisfaire la demande intérieure du riz pour le pays. Cette étude a pour objectif d’analyser les critères d’insolvabilité des contrats des riziculteurs au Burkina Faso. L’enquête terrain a concerné un échantillon aléatoire de 400 riziculteurs. Le modèle multivarié a permis d’analyser les déterminants permettant de satisfaire les termes de contrat et d’assurer ainsi la solvabilité des contrats sur les plaines rizicoles. Les résultats montrent que l’accès au crédit, l’accès à la formation et les contrats formels affectent significativement les accords de prix, de la qualité et de la quantité. Ces analyses nous relèvent aussi l’importance et la pertinence des contrats de type formels pour assurer une meilleure pratique et de solvabilité des contrats rizicoles.

Despite the crucial role played by Nile perch in the income of fishers around Lake Victoria, Tanzania, fishing pressure has increased in recent years and has led to overfishing and, consequently, a risk to the lake’s future sustainability and the fishers’ livelihoods. This study used data collected in 2018 from 268 randomly selected sample fishers at 10 landing sites across Lake Victoria. In conjunction with the endogenous switching regression model, the potential impact of Nile perch overfishing on the fishers’ income per fishing trip in Lake Victoria was evaluated. The results show that there is a significant difference in the socio-economic, institutional and fishing effort characteristics of Nile perch fishers who overfish and those who do not. In particular, Nile perch fishers who overfish earn significantly higher incomes per fishing trip than fishers who do not overfish. The study recommends the need for policy makers to develop policies that acknowledge the dynamics of socio-economic, institutional and fishing effort factors. In addition, more flexible fish quota restrictions and consistent fishing patrols need to be enforced to ensure compliance with fishery regulations. These measures should promote a balance between the sustainability of fishery resources and an improved income for Nile perch fishers in Lake Victoria.
