1. Co-Production of Knowledge in Multi-Stakeholder Processes: Analyzing Joint Experimentation as Social Learning

Author

Akpo, Essegbemon, Crane, Todd A., Vissoh, Pierre V., and Tossou, Rigobert C.

Abstract

Purpose: Changing research design and methodologies regarding how researchers articulate with end-users of technology is an important consideration in developing sustainable agricultural practices. This paper analyzes a joint experiment as a multi-stakeholder process and contributes to understand how the way of organizing social learning affects stakeholders' ownership of process outcomes. Design/Methodology/Approach:A learning group composed of the different stakeholders of the oil palm seed system in Benin was set around a joint experiment. We use a detailed account of the group dynamics to understand the social process. Findings: The way the process is designed and conducted has a great effect on the ownership by the participants. Methodological steps taken in this research process showed its efficacy to produce quick and positive feedback mechanisms. Stakeholders' perspectives on what constitutes a quality oil palm seedling varied widely. Participants, mainly nursery holders, learned new production practices. Representatives of the research center learned a mismatch of recommendations with users' contexts. Field observations further to the process indicate changes in practices among stakeholders that would be sustainable. Practical Implications: Beyond focusing on outcomes, initiatives in multi-stakeholder processes should also document and analyze social processes in order to better understand the mechanisms by which such processes foster socio-technical change, as well as identify potential institutional barriers to such processes. Originality/Value: Through a detailed analysis of group dynamics, this paper addresses an important knowledge gap in participatory agricultural development.

Abstract

Le changement climatique constitue une menace permanente pour l’atteinte de la sécurité alimentaire et le bien être des ménages ruraux. Cette étude a présenté les activités, les succès, les échecs et les perceptions des bénéficiaires suite à l’intervention du programme intégré d’adaptation pour la lutte contre les effets néfastes des changements climatiques sur la production agricole et la sécurité alimentaire au Bénin (PANA1) qui avait pour objectif de renforcer les capacités de résilience des producteurs vis-à-vis des effets néfastes des changements climatiques.. Une approche qualitative basée sur la revue des documents du projet, des entretiens de groupe dans les villages d’intervention, des visites de sites de démonstration couplées avec des observations directes et participantes des infrastructures, équipements et des technologies mises en œuvre a été utilisée pour collecter les données. L’analyse participative du contenu et le recueil de quelques témoignages des bénéficiaires ont permis de traiter les données collectées. Les résultats ont révélé que les bénéficiaires apprécient l’approche participative inclusive de mise en œuvre du projet PANA1 et l’accompagnement dont ils ont bénéficié pour mettre en œuvre les technologies de renforcement de capacité de résilience. Ils attestent que leurs capitaux humain et social ont été améliorés ainsi que l’accroissement de leur productivité et leur revenu ; ce qui leur permet d’être plus résilients aux changements climatiques. Malgré que certaines technologies aient été abandonnées pour des raisons motivées, les bénéficiaires souhaitent une continuité du projet, voire sa généralisation à l’échelle nationale. English title: Strengthening the Resilience Capacity of Farming Households to ClimateChange in Benin: Results of a Diagnostic StudyClimate change is a permanent threat to the achievement of food security end the welfare of rural household. This study presents the activities, successes, failures as well as the beneficiaries’ perception on the effects of strengthening resilience capacity building measures and on food security of farm household in Benin (PANA1). A qualitative approach based on literature review of PANA 1 project’s documents, group discussion in each intervention village, field visits to demonstration sites coupled with direct and participant observations of building of infrastructures, equipment and the climate change technologies was used for data collection. Participatory analysis of collected data including beneficiaries’ perceptions and testimonies (verbatim) was made. Results revealed that the beneficiaries appreciated very much the inclusive participatory approach used by the project and the facilities it has offered to enable the implementation of the strengthening resilience capacity building technologies. They acknowledged that their social and human capitals were strengthened as well as the increase in productivity and outcome, which enable them cope with the adverse effects of climate change. In spite of some technologies were abandoned for motived reasons, the beneficiaries were enthusiastic and would like the project to continue and even be generalized at nationwide.&nbsp

Abstract

Intercropping and organic soil fertility are eco-friendly agricultural practices for sustainable agriculture. The aim of this study was to determine the yield potential and land-use efficiency of onion intercropped with groundnut under organic soil fertility management. A two-year field experiment was conducted in 2019 and 2020 under a complete factorial design with two crops and 2 varieties per crop (Bombay and creole for onion and A65 and JL24 for groundnut). Crops implementation was realized in sole and mixture under farmyard manure (FYM) single application, FYM seasonal application, FYM + NPK 1 - 1 - 2, and the control. The average yields were recorded while the intercropping efficiency was analysed using the land equivalent ratio (LER), competitiveness ratio, and aggressiveness index. Results showed that creole variety had the highest yield (17 t.ha-1) across years. FYM under single and seasonal application effectively increased the onion yield with similar values (8 to 16 t.ha-1). The LER analysis showed a yield gain for Bombay + A65 (total LER= 2.25) in 2019 and (2.38) in 2020 for Creole+A65. Analysis of competitiveness indices showed that the onion variety Bombay was more competitive than A65 (1.06). The same trend was recorded when onion variety Creole was intercropped with the same groundnut variety (1.93). FYM in single and seasonal application also affects the competitiveness of onion on groundnut (0.99 and 1.07). The present study shows that onion - groundnut intercropping under organic fertilizers could be a viable option to support the ecological intensification of onion cultivation in eastern DRC.

5. Innovating a system for producing and distributing hybrid oil palm seedlings to smallholder farmers in Benin

Author

Vissoh, Pierre V., Tossou, Rigobert C., Akpo, Essegbemon, Kossou, Dansou, Jiggins, Janice, Vissoh, Pierre V., Tossou, Rigobert C., Akpo, Essegbemon, Kossou, Dansou, and Jiggins, Janice

Abstract

This article analyses the development of a system for producing and distributing hybrid oil palm seedlings to small-scale famers. The existing seed system had become so corrupted that the seedlings actually planted were largely of unimproved kinds. The article describes institutional experiments carried out by two Innovation Platforms (IPs) in order to improve the oil palm seed system. Theory Guided Process Inquiry was used to document, evaluate and analyse these interventions. The experiments catalysed changes in inter-personal and inter-organisational power relationships that enabled further co-learning and co-construction of understanding and action among key stakeholders in the oil palm domain. The IPs and those who became local champions of seed system innovation, also triggered change in institutional behaviours, technologies, and practices that further improved the integrity of the seed system. Official nursery holders must now be trained, registered and licensed by local government. Farmers are encouraged to source hybrid seedlings only from licensed nurseries. These achievements were then shared and discussed with officials and higher level government leaders, drawing on IP members’ pre-existing professional and personal networks. Improvement of the oil palm seed system was included in the government's latest 5-year development plan.

Abstract

N° ISBN - 978-2-7380-1284-5; International audience; A survey carried out in four regions of Benin with different climatic profiles have shown producers' perceptions on climatic changes, their consequences and the different adapted measures taken by producers in order to deal with such consequences. Methodologies used comprise group discussions as well as individual interviews with open-ended, semi open and open questionnaires. The present paper is based on research results from 110 family farms of two villages in the northern region. Climate is Sudanese and the production system is cotton based. Recent climate trends perceived by producers are: irregular rainfalls, shortening of cultivation season, occurrence of violent winds and a increase of temperatures. Conventional analyses of climate series highlight significant increases of maxima and minima temperatures, although fail to show significant increases in violent winds as well as significant differences in rainfall distributions. Adaptive measures put to use by producers are many, but scarcely compensate negative effects of climate changes. Farms with little production means remain vulnerable. The study of producers' perceptions of climate changes traduces the need for a new approach in the analysis of climatic variables based on micro spatial and temporal scales.

Abstract

L’étude a pour objectif d’analyser les perceptions paysannes de la variabilité climatique et leur pertinence par rapport aux observations climatiques. À cet effet, elle a comparé des données climatiques de 14 stations et des perceptions paysannes de la variabilité climatique recueillies à partir d’une enquête auprès de 201 chefs d’exploitation (CE) agricole répartis sur 67 villages au sud-Bénin. L’enquête était constituée d’entretiens collectifs et individuels, à questionnaires ouverts, semi-ouverts et fermés. Les CE sont davantage marqués par la dégradation de la qualité des saisons des pluies observée entre 1951-1970 et 1971-1990, en l’occurrence la modification des dates de début et de fin des saisons des pluies, la recrudescence des séquences sèches, la diminution du nombre de jours pluvieux et le déficit pluviométrique, que par la relative récente reprise des précipitations au cours des années 1990 et 2000 sur la région d’étude. Toutefois, le changement d’échelle, de régionale à locale, réduit sensiblement l’écart entre les perceptions paysannes et les observations climatiques. Les CE citent également la baisse des températures et l’augmentation de la fréquence des vents violents pendant les saisons pluvieuses. Ces perceptions sont contraires aux observations climatiques et suggèrent des investigations plus approfondies pour mieux comprendre ces divergences. Face à la variabilité climatique, les CE ont développé des mesures d’adaptation qui globalement traduisent leur perception. Ceci ouvre des perspectives pour l’élaboration de stratégies d’adaptation avec une forte chance d’attirer l’intérêt des producteurs., The study aims at analyzing farmers’ perceptions of climate variability and their relevance to climate observations. Climatic data from 14 stations and farmers’ perceptions of climatic variability were collected from 201 farm managers in 67 villages in southern Benin. A combination of qualitative (informal and semi structured interviews of socio-professional groups, participant observation and triangulation) and quantitative (Structured questionnaire) approaches were used. Farmers are more sensitive to changes in rainfall patterns from 1951 to 1970 and from 1971 to 1990, particularly the shift in the onset and the end of rainy seasons, increase in the frequency of drought sequences, decrease in the number of rainfall days and rainfall deficit than the relative recent increase in precipitations that occurred in 1990 and 2000 in the study area. However, shift in scale regional or local reduce significantly the gap between farmers’ perception and climatic data. Farmers also acknowledge the decrease in temperature and the raise in the frequency of violent winds during rainy seasons. These perceptions are in contradiction with climatic data collected and suggest in depth investigations to better understand these divergences. In order to mitigate climatic variability, farmers have developed adaption strategies mostly based on their perception. This offers window of perspectives to develop adaptation strategies based on farmers’ perception and interests.
