RISE : a network approach towards promoting farmer entrepreneurship in Africa

This paper presents the backgrounds and activities of the KB project ‘Rural Innovation Systems and Enterpreneurship’ which is strongly articulated to the Agri-Profocus networking approach and agri-hubs in nine African countries. Five subjects relating to coinnovation and learning are developed

Les 25 Résolutions de Konni

Niger is the largest exporter of onions in West Africa. More than 100.000 Nigerian peasants cultivate onions. For them and all the other operators within the chain (intermediaries, tradesmen, shipping agents), the onion is an important source of income. SNV Niger, and Wageningen UR Centre for Development Innovation in the Netherlands, in collaboration with FCMN Niya and Agri-Bilan, initiated an action research titled “Peeling the onion”. The goal of this action-research is to identify possibilities of collective action for all the actors in the value chain of the onion. The research focusses on ‘leverages’ to induce changes which make the onion subsector in one time more competitive, inclusive and sustainable. After this first phase, we shared our results during this participative workshop in Birni Konni in the area of Tahoua. Moreover one stimulated the dialogue between the various actors within the value chain of the onion resulting in the 25 resolutions of Konni! This report is the result of this workshop and dialogues

Eplucher l'Oignon : Pour une filière oignon nigérienne compétitive et inclusive

Perceptual learning is associated with experience-based changes in stimulus salience. Here, we use a novel procedure to show that learning a new association between a self-label and a neutral stimulus produces fast alterations in social salience measured by interference when targets associated with other people have to be selected in the presence of self-associated distractors. Participants associated neutral shapes with either themselves or a friend, over a short run of training trials. Subsequently, the shapes had to be identified in hierarchical (global-local) forms. The data show that giving a shape greater personal significance by associating it with the self had effects on visual selection equivalent to altering perceptual salience. Similar to previously observed effects linked to when perceptually salient distractors are ignored, effects of a self-associated distractor also increased activation in the left intraparietal cortex sulcus. The results show that self-associations to sensory stimuli rapidly modulate neural responses in a manner similar to changes in perceptual saliency. The self-association procedure provides a new way to understand how personal significance affects behavior

Knowledge Sharing Idiosyncrasies of University Students in Ghana

Part 6: Decision Making and Knowledge ManagementInternational audienceThis study explored the factors affecting knowledge sharing behaviour of students in a higher institution of learning. Using a model derived from the Social Cognitive Theory and the Theory of Reason Action, six hypotheses were tested from a cross-sectional data collected from 371 undergraduate students on a 4-year degree programme in the University of Ghana. Five out of the six hypotheses were supported. The results showed that the knowledge sharing behaviour (KSB) of the students was significantly related to five of the human and environmental factors (F=639.9, df=5, 290, p<0.05) with a co-efficient of variation of R2=0.917 (91.7%). The knowledge sharing behavior of the students was, however, not significantly dependent on their personal characteristics. The study makes a case for increased attention in understanding the human and environmental factors of knowledge sharing since knowledge sharing is largely a people activity shaped by culture
