Benin is highly dominated by agriculture: about 80 % of the population are rural and involved in farming activities. The challenge now is to create suitable conditions for the improvement and competitiveness of farming systems and the creation of small and medium enterprises along the different chains of agricultural value. One such challenge involves facilitating the access of farmers and other stakeholders, to input markets, products and especially financial services. This highlights the need to establish an optimal framework for financing agricultural activities based on lessons learned from current experiences and using the best recent institutional innovations in the field. This thesis focuses on the issue of funding for agriculture and strategies developed by producers and other stakeholders including the public sector. To understand agricultural activities financing problems in rural areas, a research was conducted from 2010 to 2014. The research targets are farms and their access to financial services. A survey of 475 farms was conducted in 2011. In 2014, a deepening phase was performed on 40 farms. Research results revealed that financial needs of farms are not totally satisfied. The loans granted are small amounts, mostly. Productive investments that constitute investments in medium and long term, which can lead to significant improvements in agricultural production, are almost unsatisfied. Moreover, analysis showed that income determines access to credit. This factor reflects to a certain level the ability of farmers to provide the financial guarantees required by microfinance institutions. Also, producer's ability to invest and to provide the required guarantees, his loyalty and compliance with the rules of microfinance institutions (MFIs) facilitate access to high loan amounts. Analysis also showed that credit rationing affects a large number of producers. The consequence of this rationing is the reduction in agricultural inputs use, in hired labour, in acreage, etc. And therefore, decrease in yields and producers incomes. In summary, current conditions offered by microfinance institutions is not conducive to agricultural development and livelihoods improvement of rural populations. It is therefore necessary to rethink agricultural activities funding and develop a sustainable financing mechanism for both producers and funding agencies. To this end, the initiative for the establishment of a National Fund for Agricultural Development (NFAD) should be accelerated to allow farmers easier access to credit and adequate. [less ▲]

Distinguishing the analysis of spatial data from classical analysis is only meaningful if the spatial components bring information. Therefore, testing if the spatial autocorrelation is significant may confirm or deny the need to consider spatial analysis over the classical one. Spatial autocorrelation expresses the dependence between values at neighbouring locations. Several measures of spatial autocorrelation are defined in the literature. Moran’s index, Geary’s ratio and Getis-Ord statistic are the most used statistics. Tests based on these measures have been developed in the literature using asymptotic and permutation results. They are used in practice in many fields, for instance in geography, economics, biogeosciences, medicine, ... However, these tests should be cautiously applied because they are not robust. A single contaminated observation can significantly modify their results. The talk has two main objectives. Firstly, the already available tools for measuring spatial autocorrelation will be reviewed with an emphasis on the study and comparison of their robustness. Secondly, alternative methods will be proposed to robustly estimate the spatial autocorrelation. [less ▲]

In the context of energy demand side management (DSM), energy storage solutions are needed to stock energy during high production periods and recover energy during high demand periods. Among currently studied solutions, storing energy in the subsurface through heat pumps and/or exchangers (thermal energy storage) is relatively simple with low investment costs. However, the design and functioning of such systems have strong interconnections with the geology of the site which may be complex and heterogeneous, making predictions difficult. In this context, local temperature measurements are necessary but not sufficient to model heat flow and transport in the subsurface. Electrical resistivity tomography (ERT) provides spatially distributed information on the temperature distribution in the subsurface. In this study, we monitored, with 4D ERT combined with multiple hydrological measurements in available wells, a short-term heat storage experiment in a confined alluvial aquifer. We injected heated water (ΔT=30K) during 6 hours with a rate of 3 m³/h, stored during 3 days, and then we pumped it back to estimate the energy balance. We collected ERT data sets using 9 parallel profiles of 21 electrodes and cross-lines measurements. Inversion results clearly show the ability of ERT to delimit the thermal plume growth during injection, the diffusion and decrease of temperature during storage, and the decrease in size after pumping. Quantitative interpretation of ERT is difficult at this stage due to strong spatial variations of the total dissolved solid content in the aquifer, due to historical chloride contamination of the site. Energy balance shows that up to 75% of the energy can be easily recovered with an adapted strategy in the context of DSM. Short-term heat storage in alluvial aquifer is efficient and ERT is a valuable tool to image and estimate the temperature distribution in the subsurface. [less ▲]

Representations are a key factor in the development of a physically active lifestyle. In women, it is fundamental to verify if there are not wrong represnetations about physical activity because that could be an important barrier to any change. This workshop will propose several activities aiming to show how it is possible to increase the awareness of people about what is physical activity and how to accept to reach the international recommendations.

The univariate coefficient of variation (CV) is a widely used measure to compare the relative dispersion of a variable in several populations. When the comparison is based on $p$ characteristics however, side-by-side comparison of marginal CV's may lead to contradictions. Several multivariate coefficients of variation (MCV) have been introduced and used in the literature but, so far, their properties have not been much studied. Based on one of them, i.e. the inverse of the Mahalanobis distance between the mean and the origin, this talk intends to demonstrate the usefulness of MCV's in several domains (finance and analytical chemistry) as well as provide a complete inference toolbox for practitioners. Some exact and approximate confidence intervals are constructed, whose performance is analyzed through simulations. Several bias-correction methods, either parametric or not, are suggested and compared. Finally, since MCV's are used for comparison purposes, some test statistics are proposed for the homogeneity of MCV's in $K$ populations. Throughout the talk, the robustness of the techniques will be discussed. As a by-product, a test statistic allowing to reliably compare $K$ univariate CV's even in presence of outliers will be outlined. [less ▲]

The Sahelian's environment suffered many perturbations increasing the food insecurity risks. Since three decades, the environment suffered a intense and significant land deterioration (Warren A. And al., 2001). A lot of regreening actions have been developped in the Sahelian countries but some actions are most sustainable and the costs are lower than the other. The International Fund for Agricultural Development (IFAD) has developped some actions to strengthen the natural ressources management. The most important actions have been introduced from the mi-term of 1,980 (Sendzimir J. And al., 2011). These actions concerned the main water and soil conservation technics: Zaï; „contour“ stone bund; half-moons; permeable rock dams (Wesel A., Rath T., 2002). The paper attempts to answer about the following question: „what are the indirect and direct socioeconomic impacts of the natural ressources management in the Maradi’s region ?“. Moreover, Maradi is the historical area of the IFAD actions and illustrates some major causes of land degradation. The main causes are the increase of demography and agricultural areas. In fact, the demography and agricultural area of Maradi are seriously worrying: 8 children per women and the agricultural area is less than 1 hectare per household (Andres L., Lebailly Ph., 2013). The paper relates and describes the main anti-erosion technics. It compared also the cost-benefit analysis about the soil and water conservation technics. Finally, the report try to establish a key who links the technics with the context (soil, people, environment, agriculture, livestock) (Moussa Dit Kalamou M., 2015; Jasmien C.J. and al., 2013).

Le syndrome psychotique chez l'enfant est un syndrome d'évolution neuro-développementale très fréquent dans l'enfance mais souvent diagnostiqué avec un retard de deux années ou davantage. Une bonne connaissance de ce qu'est « un syndrome psychotique » est indispensable pour les professionnels de l'enfance. D’autres modules antérieurs de formations sont proposés par l'auteur du document présent afin d'en donner connaissance. Le module de formation ici présenté donne des points de repères pour une « Évaluation du cadre des prises en charge » du syndrome psychotique du jeune enfant. On trouvera successivement : 1) une définition générale du syndrome psychotique — 2) le fondement général des prises en charge — 3) les différents niveaux des paramètres déterminant les prises en charge : 3A) l'enfant, 3B) les parents et la fratrie, 3C) l'école et les enseignants — 4) quelques pistes de propositions : 4A) pour les intervenants dans leur relation à l'enfant, 4B) pour les psychothérapeutes, 4C) pour les enseignants, 4D) pour les entretiens avec les parents — 5) des réflexions sur les réévaluations et l'interaction en réseau.

Au départ des études sur la culture matérielle, le lien entre les choses et les sujets, établi par le biais du corps, sera exploré. La consommation, en tant que moyen d’incorporation des objets dans le soi et dans son propre univers de référence, constituera la porte d’entrée de l’analyse de ce lien. De l’élaboration des choix à la dé-marchandisation des produits, le processus qui engage simultanément choses et sujets jette les bases de la définition individuelle et des relations sociales. L’alimentation en est un exemple concret. Pratique qui stimule la réceptivité multidimensionnelle du corps, elle permet également de s’interroger sur le rôle de celui-ci non seulement dans les dynamiques de consommation mais aussi dans les démarches ethnographiques visant leur compréhension.
