Using the Ordered Probit Model to Predict Drivers for Adoption of Multiple Soil Fertility Management and Conservation Technologies in Potato Production Systems in Uganda

La baisse du niveau de fertilité des terres cultivables du fait des pratiques agricoles inadaptées, de la déforestation et du changement climatique reste l’une des contraintes majeures de l’agriculture béninoise. Les mesures de Gestion Intégrée de la Fertilité des Sols (GIFS) en sont une des approches de gestion durales des terres à l’échelle des exploitations agricoles. Ainsi, l’étude a fait usage d’un modèle probit multivarié pour identifier les déterminants de l’adoption des mesures de GIFS au sein des exploitations agricoles productrices de maïs au Nord-Bénin. Elle a été conduite sur un échantillon de 100 producteurs de maïs sélectionnés suivant un sondage aléatoire stratifié. Les résultats ont révélé l’existence d’une interdépendance et de complémentarités dans l’adoption des différentes mesures de GIFS. Aussi, la majorité des producteurs de maïs enquêtés préfèrent adopter une combinaison de deux mesures de GIFS (32%) ou de trois mesures (26%). Par ailleurs, la distance du village au champ, l’appartenance à un groupement, le contact avec la vulgarisation, la superficie emblavée en maïs, la taille du cheptel et le nombre d’actifs agricoles restent les principaux facteurs déterminants l’adoption de ces mesures de GIFS par les producteurs.Mots clés : Bénin, changement climatique, gestion durable des terres, Gestion Intégrée de la Fertilité des Sols, pratiques agricoles, probit multivarié. English title: Adoption of integrated soil fertility management measures in northern Benin: an application of the multivariate probit model to the case of maize producers The decline in the level of fertility of arable land due to unsuitable agricultural practices, deforestation and climate change remains one of the major constraints of agriculture in Benin. Integrated Soil Fertility Management measures (GIFS) are one of the sustainable land management approaches that have been promoted at the level of farmers’ communities. Thus, the study made use of a multivariate probit model to identify the determinants of the adoption of GIFS measures within maize-producing farms in North Benin. It was carried out on a sample of 100 maize farmers selected following a stratified random survey. The results revealed the existence of interdependence and complementarities in the adoption of different GIFS measures. The majority of maize producers surveyed prefer to adopt a combination of two (32%) or three GIFS measures (26%). In addition, the distance from the village to the field, the membership of a group, the contact with the extension service, the area sown with maize, the size of the herd and the number of agricultural workers were identified as the important factors determining the adoption of these GIFS methods by producers.Keywords: Benin, climate change, sustainable land management, Integrated Soil Fertility Management measures, agricultural practices, multivariate probit.

Farms face declining soil fertility. Maintaining this fertility becomes a concern for famers who adopt several strategies to this end. Hence, it is important to know these strategies to better improve and value them. It is in this context that a study was carried out in 15 villages within three municipalities of Tillabery region in Niger. Its objective is to study farmers soil fertility management perceptions and strategies in the municipalities of Gotheye, Tagazar and Torodi. Data collection was carried out through individual surveys of 300 farm managers, with 20 per village, or 100 per municipality. The respondents are mainly illiterate (56%) with agriculture (82%) and house farming (88%) as main activities. They said the soils are poor. Their indicators are soil color (40%), good germination (24%), yield (23%), and soil poorness indicator species (13%). To overcome this, farmers use more manure which is managed sparingly. However, the fallow, neglected by the majority of farmers, lasts only 2 or 3 years. The promotion of integrated soil fertility management through ANR, the use of manures and degraded lands restoration techniques are necessary for the sustainability and improvement of production systems.

AbstractIn Europe, the lack of specific rules regulating organic vegetable production in protected conditions has led to the implementation of extremely diversified systems of production, at different level of intensification. In this study, we compared three strawberry organic production systems based on the following main criteria of soil fertility management: input substitution (SB), a simplified system of organic production that mimics conventional agricultural practices and two systems characterized by a more complex soil fertility management, based on the introduction, in the rotation of agroecological service crops (ASCs) and compost (AC), and of ASCs and cattle manure (AM). Strawberry yields, in the compared systems, were not significantly different in both years of our research, while, as a whole, the yield in 2013 (30.3 Mg ha−1) was significantly higher than in 2014 (28.9 Mg ha−1). Crop nitrogen (N) needs, during the entire cycle of production, were satisfied according to the same pattern by SB, AC and AM, while green manuring and organic amendments in AM and AC determined a higher soil organic N content, compared with SB. As far as the production quality is concerned, both AM and AC treatments yielded strawberry fruits similar to SB, but with better characteristics in terms of color and phenolic content. AM and AC did not differentiate statistically in the two year period of our research.

Purpose The purpose of this paper is to evaluate the non-monetary effect of credit access by providing an econometric framework which controls the problem of selection bias. Design/methodology/approach The study is conducted in Assam, India and uses a quasi-experiment design to gather primary data. The ordered probit model is used to evaluate the non-monetary impact of credit access. The paper uses a propensity score approach to check the robustness of the ordered probit model. Findings The study confirms the positive association of credit access to life satisfaction of borrowers. It is found that, in general, rural borrower’s life satisfaction is influenced by the ability and capacity to work, the value of physical assets of the borrowers as well as some other lenders’ and borrowers’ specific factors. But, the direction of causality of the factors influencing borrowers’ life satisfaction is remarkably different across credit sources. Research limitations/implications The study argues to provide productive investment opportunities to semiformal and informal borrowers while improving their life satisfaction score. Although the results are adjusted for selection and survivorship biases, it is impossible with the available data to assess which non-income factors explain the findings, and therefore this limitation is left to future research. Originality/value The study contributes to the literature of rural credit by assessing the probable differences among formal, semiformal and informal credit sources with respect to non-monetary impacts.
