Traditional yam cropping practices in West Africa deliver low yields and lead to environmental degradation. In the context of a ‘research for development’ project, we developed and implemented a participatory and transdisciplinary research approach as a means to derive more sustainable yam production practices. We identified and studied different soil and plant management technologies adapted to varying biophysical and socio-economic contexts. For this purpose, we established innovation platforms (IPs) in four yam growing regions of West Africa, to validate the new technologies and to promote their adoption. These co-developed technologies were set up and tested first in researcher-managed plots before doing the same in farmer-managed plots. The new technologies resulted in a significant increase in yam productivity compared to convention...

Its impact on agricultural activities in developing countries has increased dramatically. Understanding how farmers perceive climate change and how they adapt to it is very important to the implementation of adequate policies for agricultural and food security. This paper aims to contribute to an understanding of farmers’ adaptation choices, determinants of the adaptation choices and the long-term implications of the adaptation choices. Data were collected from 120 respondents in the Zou Department of Benin. A binary logit model was used to analyze the factors influencing household decisions to adapt to climate change. Multinomial logistic regression analysis was estimated to analyze the factors influencing households’ choice of adaptation strategies to climate change. The results show that farmers have a developed perception of climate change. These changes are translated by rainfall disturbances (rainfall delays, early cessation, bad rainfall...

Such events may affect the functioning of farm systems and threaten their capacity to provide food in adequate quantities and sufficient quality. The capacity of farm systems to recover, reorganize, and evolve following external shocks and stresses is analysed within the framework of resilience theory. The SHARP (self-evaluation and holistic assessment of climate resilience of farmers and pastoralists) tool was developed to assess the resilience of farm systems to climate change in a participatory way. The SHARP was originally designed for developing countries. This paper outlines the process and changes made to adapt the tool for use in the Swiss farming context, including the challenges and trade-offs of the adaptation. Its first application in the Canton of Vaud provides insights on the levels of resilience to climate change for farmers in Switzerland. The results showed that of twenty-five farmers, “e...

This crop has a high cultural value for some of the groups growing it. Most of the production comes from West Africa where the increased demand has been covered by enlarging cultivated surfaces while the mean yield remained around 10 t tuber ha-1. In West Africa, yam is traditionally cultivated without input as the first crop after a long-term fallow as it is considered to require a high soil fertility. African soils, however, are being more and more degraded. The aims of this review were to show the importance of soil fertility for yam, discuss barriers that might limit the adoption of integrated soil fertility management (ISFM) in yam-based systems in West Africa, present the concept of innovation platforms (IPs) as a tool to foster collaboration between actors for designing innovations in yam-based systems and provide recommendations for future research. This review shows th...

L’une de ses batailles vise la revalorisation des produits des terroirs. Mais pour un fromage, un vin, une viande, comment circonscrire une région spécifique, une saveur, une méthode traditionnelle? Comment protéger un nom, Gruyère par exemple, et se défendre contre les imitations et les publicités trompeuses? Comment garantir, du côté des producteurs, une qualité précise?
Les appellations d’origine contrôlées, idée venue de France, mobilisent en Suisse législateurs, agronomes, économistes, gastronomes et les associations qui fixent, avec l’Etat, des règles complexes. Aussi cet ouvrage, décrivant une action politique très actuelle, a-t-il requis la collaboration d’experts de l’agriculture, des lois du marché et du goût. Il initie au domaine des AOC et des IGP (indications géographiques protégées) tous les consommateurs qui cherchent à se nourrir hors de la banalité.

Et les voici payés pour qu’ils sauvegardent l’environnement. C’est une mutation historique de l’agriculture, décrite dans chacune de ses étapes et dans l’évolution des objectifs. Les exploitations sont appelées à faire face aux nouvelles technologies et aux exigences des marchés et traités internationaux. Elles sont sommées de répondre aux aspirations d’une population attachée à des paysages que l’urbanisation par ailleurs envahit. La politique agricole conduit ainsi aux problèmes brûlants qui émergent, la gestion de l’espace et des biotopes, les sources d’énergie, la santé publique et finalement, à l’échelle planétaire, la fondamentale nécessité, soudain redécouverte, de nourrir les hommes.

Comté in France, Gruyère in Switzerland, the cheese and milk prices are above average whilst others as for example the Cantal from France are similar or even below average. The objective of this paper is to shed light on levers which the agents activate to assure their uniqueness is irrevocable, and uphold the benefits of their LAFS. Raising Rivals' Costs Theory gives interesting point of view about the behaviour of firms which could make use of the collective rules to raise the costs of their competitors in the particular case of LAFS oriented to the production of traditional cheeses. This will be explored through two cases studies. In the first case (territorial collective governance mode of the local supply chain), the conditions are met to conclude that the raising costs strategy corresponds to requirements which are based to a corresponding quality which meets consumers’ expectations and willingness to pay. In the second case (sectoral governance mode), few firms have taken control on the supply chain and have imposed with the time a model based on costs leadership. As conclusion, a case-by-case in-depth approach is necessary to assess whether strategy to raise costs of the rivals damages consumers welfare in the case of PDO supply chains.

The instrument used in this survey was a structured questionnaire consisting of several separate sections, including motivation toward food in general (Food Choice Questionnaire - FCQ), the specific questions about traditional and functional food and consumer socio-economic and demographic characteristics. The stratified three-staged random representative sample is applied (N=516). Based on reported frequency heavy traditional food consumers, who simultaneously reported lower level of functional food consumption (NT=196) and heavy functional food consumers with lower level of traditional food consumption (NF=60) are identified. A descriptive statistical analysis (parametric and non-parametric) is conducted with the aim to investigate all statistically significant differences between two consumers’ group profiles.
The heavy traditional dominate over heavy functional food consumer group in Serbia. “Traditional food” in Serbia is perceived as home-made, tasty and healthy, with long heritage. Rank of motivations is very similar: after ‘taste’ - ‘price’, ‘natural content’ and ‘health’ are most frequently chosen by both consumers groups. However, the heavy traditional food consumers are more old, therefore unemployed (as retired people are considered as unemployed) and exposed to social influences. Differences in age and education between two compared consumers groups indicate possible transition of diet pattern toward more frequent functional food consumption.
