| The net impact of pest-resistant GM crops on the welfare of both producers and consumers in developing countries is currently unknown and subject to speculation. This study uses choice-based conjoint protocol to estimate the net impact of pest-resistant Genetically Modified (GM) cowpea on net social welfare in Benin given price and income risks. Results imply that Bt cowpea will increase expected net social welfare by about $US 50 million per year in Benin given no inefficiencies in the seed sector. If inefficiencies in the seed sector are such that cowpea growers can access Bt cowpea seeds only 50% of the time, net benefits from Bt cowpea drop to about $US 11 million per year. |

| Contrairement aux cultures de rente et vivrières pour lesquelles l’Etat a mis en place un minimum de politique, des moyens de production et de distribution de semences améliorées, les cultures maraîchères n’ont pas bénéficié d’un appui substantiel sur ce plan. L’objectif de cette étude est d’identifier et de caractériser les acteurs du système semencier des cultures maraîchères au Bénin, de déterminer les facteurs qui affectent la demande des producteurs en semences améliorées dans les structures formelles. Les données ont été collectées auprès de 284 producteurs répartis dans trois communes : Cotonou et Grand-Popo (Sud et Sud-ouest), Malanville au Nord-Est. Les résultats obtenus à l’aide de la revue de littérature, de la statistique descriptive et d’une... |

| Le présent article vise à analyser les facteurs déterminant la préférence des consommateurs et leur consentement à payer pour bénéficier des attributs du riz local et du riz importé. Le modèle de prix hédonique a été utilisé pour déterminer les prix marginaux implicites des attributs du riz local et du riz importé. Les données aussi bien quantitatives que qualitatives ont été collectées auprès d’un échantillon de 233 ménages consommateurs de riz repartis dans deux départements du Bénin (Collines et Littoral). Il ressort des résultats que pour le riz importé, les prix marginaux implicites sont de 45,3FCFA pour l’absence de corps étrangers, 46,25FCFA pour la disponibilité toute l’année, 51,66 FCFA pour la blancheur, 16,21FCFA pour l’arôme et 14,11FCFA pour... |

| Vegetable plays important roles in the socio-economic development in West Africa. It contributes to insuring food security, provides raw materials for local industries, generates foreign exchange and provides employment and incomes for most of the population. However some health hazards are caused by the misuse of chemical on vegetable. This study is undertaken within the framework of the research project: Public-private partnerships for development and implementation of entomopathogenic viruses as biopesticides for key lepidopteran pests in Ghana and Benin. It assesses the potential market of organic vegetables and analyse consumers awareness and perceptions of chemical pesticide residues in vegetables and assess the premium levels that consumers are... |

| Household characteristics are commonly used to explain variation in smallholder efficiency levels. The underlying assumption is that differences in intended behavior are well described by such variables, while there is no a priori reason that this is the case. Moreover, heterogeneity in farmer goals and preferences, in relation to the role of the farm enterprise, are not well documented in developing countries. This paper makes a contribution to fill this gap, by empirically determining heterogeneity in farmer goals and attitudes in Nigeria through a pair-wise ranking, supplemented with Likert scales. Factor analysis is used to reduce these data into behavioral factors. We estimate technical and allocative efficiency levels and analyze how these are... |

| Intensifying inland valley systems will require the promotion of high value commodity chain system involving rice and vegetable with increased productivity and low per unit cost of production and natural resources. The objective aim to identify the current production systems assesses their constraints and analyzes the profitability of best bet rice and vegetable cropping systems under different levels of input use and access to market. A total of 235 producers selected in Benin and Mali according to input use and access to product market. The value chain approach used to analyze the performance associated with productivity. The results show that four main chain stakeholders operate in the inland valley: producers, processors, trader and consumers. This... |

| Pests and diseases caused by bacteria, nematodes, fungi and viruses cause significant losses to tomato in West Africa. This study, carried-out within the framework of the IPM-CRSP implemented jointly by IITA, IER and Virginia Tech. and State University, assesses farmers’ perceptions on tomato pests and analyzes factors affecting pest management decision-making. Surveys were carried out in three tomato production areas where pests and diseases are major agricultural problems encountered by farmers. Data were collected a sample of from 343 farmers through a set of questionnaires on tomato production systems. Farmer’s decision-making in pest management was modeled using an econometrics Logit probability model. Results show that the main disease reported by... |
