SYNERGIES ENTRE RECUPERATION DES EAUX DE RUISSELLEMENT ET FERTILISATIONS MINERALES DANS LES PAYS SAHELIENS, POUR ACCROITRE LA SECURITE ALIMENTAIRE, FAIRE FACE A LA CROISSANCE DEMOGRAPHIQUE, S’ADAPTER AUX CHANGEMENTS CLIMATIQUES ET LIMITER LES EMISSIONS DE GES.

Au Nord du Burkina Faso les rendements en grain en 1992 du sorgho passèrent de 0,063 t.ha-1 pour les témoins à 0,976 t.ha-1  sur  zaïs  (micro-cuvettes d’environ 0,12 m3) avec 65 unités de NPK  et 3 t de compost. L’intensité territoriale (IT) par tonne de grain a été divisée par 15,5 en 1992. Mais alors que les précipitations annuelles en 1993 furent seulement inférieures de 10% par rapport à 1992, les rendements des témoins furent divisés par 3 pour les témoins et par 2 sur zaïs. Pour le maïs la production moyenne de 2012 à 2014 est passée de 0,8 t.ha-1  pour les témoins à 2,215 t.ha-1 à Yatenga et à 2,88 t.ha-1 à Bam, avec irrigation complémentaire avec des  bassins de 200 m3 et des fertilisations (155 unités par ha). L’ITmoyenne est passée de 1,25 ha à 0,45 ha à Yatenga et à 0,35 ha à Bam. Pour le maïs les rendements furent également plus réguliers et plus élevés avec des irrigations complémentaires associées à une fertilisation. L’ITP6S%c (superficie pour une ration supplémentaire calorique annuelle de 162,5 kg de grain) a pu être diminuée dans les mêmes proportions. Les consommations d’énergie, d’eau et les émissions de GES par tonne de produit diminuèrent également.L’adaptation en Afrique doit donc cibler prioritairement et conjointement la récupération des eaux de ruissellement, par bassins plutôt que par micro-cuvette, afin de sécuriser l’efficacité des apports d’engrais, de mieux valoriser les terres disponibles et les précipitations.Mots clefs : Adaptation aux changements climatiques, efficacité de l’utilisation des terres et de l’eau,  maïs et du sorgho, Zaïs (cuvettes) et bassin de réception des ruissellements, Sahel, Fertilisation et compost

ANALYSIS OF PLANNING, BUDGETING AND ACCOUNTING FUNCTIONS OF INTEGRATED FINANCIAL MANAGEMENT INFORMATION SYSTEMS (IFMIS) AND PUBLIC FUNDS MANAGEMENT IN THE LOCAL GOVERNMENT - THE CASE OF NYAMASHEKE DISTRICT, RWANDA

The study entitled “Analysis of planning, budgeting and accounting functions of Integrated Financial Management Information Systems (IFMIS) and public funds management in the local government. Case of Nyamasheke District, Rwanda (2015-2022)” was conducted to achieve three specific objectives such as: to analyze the significance of IFMIS planning function on public fund management in Nyamasheke District, to assess the significance of IFMIS budgeting function on public fund management in Nyamasheke District and to examine the significance of IFMIS accounting function on public fund management in Nyamasheke District. To achieve study objectives, the study used descriptive, quantitative, and correlative research designs. Primary data and secondary data also were used. Primary data were collected from 152 staff in Nyamasheke district who have relation to the IFMIs use and management from different entities from district to sector level. Data collection was done using a questionnaire and documentation. Data analysis was done with the support of SPSS version 20 to generate a linear regression model and bivariate correlation model as well as descriptive statistics. The study findings show that the model had an F ratio of 42.474 and the P value was 0.000<0.000, signifying that the F ratio was statistically significant, therefore the overall regression model for all the variables tested was statistically significant and can be used for prediction at 5% significant level. This further indicates that the predictor variables (Planning (P), Budgeting (B), and Accounting (A) used in this study as IFMIS functions are statistically significant to the public fund management in Nyamasheke District. Therefore, the formulated Null Hypothesis stating that there is no significant influence of IFMIS planning, budgeting, and accounting IFMIS functions on the public fund management in Nyamasheke District, failed to be accepted in favor of the alternative hypothesis or its opposite. The conclusion of the study relies on the acceptance or failure to accept study hypothesizes. Based on the H0 or Null Hypothesis “There is no significant influence of IFMIS planning, budgeting, and accounting IFMIS functions on the performance of public fund management in Nyamasheke District” the results show that the planning, budgeting, and accounting as IFMIS functions each contribute 68% to the implementation of public funds management in the local government, case of Nyamasheke District. Due to that, the conclusion relies on the rejection of the Null Hypothesis and considers the alternative hypothesis or its opposite. JEL: M10; M40; M41  Article visualizations

Farmers’ Perception and Willingness to Pay for Climate Information in Burkina Faso

peer reviewedThis study highlights the perception and the option value of climate information in the sahelian and sudano-sahelian agro-climatic zones of Burkina Faso. From the sampled farmers only 21.78% have access to climate information, while 93% of them need climate information to guide through their decision in planning agricultural activities. Option value shows the interest granted by farmers using climate information. About 64% of the farmers are willing to pay an average of Francs CFA 546.34 to obtain climate information. The willingness to pay is determined by the the farmers’ ability to predict the climate, to use radio as a means of information, farmers’ awareness of previous forecasts and early onset of rainy season. While farmers considered benefits from the use of climate information, it is clear that its contribution to farm income remains a field of research to explore. Thus it is necessary to experiment with individual farms and to evaluate the contribution of climate information to the value added in different crops and farmers’ income
