Deep-rooted debates on finding a lasting solution to this problem using agriculture have been targeted as one of the panaceas. Using data from 207 systematically selected rice-producing households, this study employed the Propensity Score Matching method (PSM) and the Inverse Probability Weighted Regression Adjustment method (IPWRA) to examine the effect of intensive youth participation in agriculture on productivity and household revenue in Nigeria. We found that the key factors influencing the decisions of youth to participate in agriculture intensively include the number of years of farming experience, access to credit, membership in social groups, income, and land access. The PSM results indicate that rice productivity could increase by 1088.78 kg/ha if youth decide to intensively participate in agriculture. The IPWRA results show a positive ...

Accordingly, the Nigerian government implemented several interventions, including the Youth-in-Agribusiness (YIA) program to reduce youth unemployment. However, the effect of these programs on gainful employment creation is yet to be documented. Therefore, this study examined the impact of the YIA program on creating gainful employment among the youth. Multistage random sampling was used to obtain cross-sectional data from 668 youth in Southwestern Nigeria. Propensity score matching and endogenous switching probit techniques were used for the estimations. Results indicated that variables such as educational attainment, access to training, non-agricultural activity, membership in a youth organization, access to credit, productive resources, and youth location were significant and positively influenced youth decision to participate in the YIA pro...

This paper reported an updated data on pyrethroids/DDT resistance in theAn. gambiae s.lpopulation from Togo. Methods:From December 2013 to April 2015, females of indoor-restingAn. gambiae s.lwere captured in three locations belonging to three different ecological zones. Resistance to DDT, permethrin and deltamethrin was screened in F1 progeny of collected mosquitoes using WHO susceptibility tests. The identification of species ofAn. gambiaecomplex and the detection ofkdrandace.1Rallele were carried out using DNA-based molecular techniques.Results:An. gambiaefrom Kovié and Nangbéto were highly resistant to DDT and permethrin with mortalities rate ranging from 0.83% to 1.58% for DDT and zero to 8.54% for permethrin. Mosquitoes collected in Nangbéto displayed 81.53% mortality with deltamethrin....

However, if improved water management strategy is adopted during rice cultivation, it may help to reduce malaria cases among human population living around rice fields. This study aimed to assess the impact of the different irrigation practices on malaria transmission, as well as to evaluate the water management system that will best mitigate malaria transmission in Malanville, Benin. Methods Knowledge, Attitude and Practice (KAP) study was conducted on 104 households staying on and around the rice fields in Malanville. The study focused on the frequency of mosquito bites and preventive measures against malaria as well as soil preparation and rice planting methods. Mosquito larvae density was assessed in different water management system: continuous flooding (CF) or intermittent flooding (IF), deep tillage (DT) or minimal tillage (MT) an...

Les produits du Bénin sont achetés trois fois moins chers que ceux du Ghana. La correction de cette situation passe par le développement et l’adoption de technologies appropriées. La connaissance et la prise en compte des pratiques existantes affectant la qualité de l’amande et du beurre sont nécessaires pour le développement et la diffusion des technologies. La présente étude s’est consacrée à l’inventaire des principales pratiques ou techniques endogènes de traitement du karité et à l’identification de celles qui sont appropriées. Une enquête a été réalisée auprès de transformatrices dans les cinq parcs à karité du Bénin en vue de recenser les savoir-faire endogènes en matière de transformation des fruits de karité en beurre, de les analyser et les comparer aux pratiques recommandées. Ainsi, 130 transformatrices choisies de façon aléatoire ...

It is known that the main threat to effective malaria vector control is the selection of insecticide resistance in field Anopheles population. This study aimed to generate baseline data on the mechanisms involved in insecticide resistance in An. gambiae s.l. population from Kpome. This information is useful for a proper evaluation of new formulations of vector control tools expected to be deployed in resistance management. Methods: Indoor-resting Anopheles mosquitoes were collected using electric aspirators. The insecticide susceptibility level of F1 adult offspring of An. gambiae s.l. was assessed using the WHO standardprotocol. Genotyping of insecticide resistant alleles and Plasmodium detections were carried out using TaqMan assays. Results: WHO susceptibility test showed that An. gambiae s.l. from Kpome is highly resistant to DDT and ...

Among the latter, vegetable farming is positioned as strategic cropping for meeting urban and periurban food consumption in most West African countries. Seasonality differences between coastal and sahelian countries, coupled with, the logic of vegetable producers, and the requirements of crops and the prices variability resulted in the development of production and marketing strategies favorable to market integration in West African countries. This study aims at providing preliminary information on tomato market integration between Benin and Burkina Faso. Data from fields surveys and on monthly prices, extracted from ONASA and DGSA databases are used to analyze the regional market integration. Cointegration models based on Johansen approach and Autoregressive Distributed Lag approach of Pesaran are used for analysis. The hypothesis on the existence of a potential weak integration ...

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.

Markets for insects as food are also expanding worldwide. To inform the development of insect-based foods, we analysed selected minerals (Fe-Mn-Zn-Cu-Mg) in wild-harvested and commercially available termites. Mineral values were compared to selected commercially available insects. Alate termites, of the genera Macrotermes and Odontotermes, showed remarkably high manganese (Mn) content (292–515 mg/100 gdw), roughly 50–100 times the concentrations detected in other insects. Other mineral elements occur at moderate concentrations in all insects examined. On further examination, the Mn is located primarily in the abdomens of the Macrotermes subhyalinus; with scanning electron microscopy revealing small spherical structures highly enriched for Mn. We identify the fungus comb, of Macrotermes subhyanus, as a potential biological source of the high Mn concentrations. Consuming even small quantities of termite alat...
