La sécheresse qui sévit dans le Sahel depuis les années 1970 a fortement réduit les productions dans les principaux secteurs d’activités que sont la pêche, l’élevage et l’agriculture. Dans le Delta Intérieur du Niger au Mali (DIN), la pêche dont le développement est intimement lié aux fluctuations inter-saisonnières et interannuelles de la crue du fleuve Niger, est en crise. Les prises ont diminué de moitié, beaucoup de pêcheurs sont partis, certains ont adopté des pratiques non durables et les règles sociales subissent d’importantes modifications.
Les notions de services environnementaux et de services écosystémiques (SE) ont connu un rapide engouement au cours de la dernière décennie et sont à l’origine de nouveaux instruments pour faire face à divers problèmes environnementaux, notamment la déforestation : les dispositifs de Paiements pour Services Environnementaux (PSE). Néanmoins, l’intégration du concept dans les politiques publiques reste un processus rare.
L'article propose d'utiliser le concept de sécurisation alimentaire pour étudier les actions et processus qui améliorent une situation alimentaire, plutôt que celui de sécurité alimentaire qui se réfère avant tout à la satisfaction de besoins alimentaires. Dans une première partie, ces deux concepts sont précisés et discutés. La sécurité alimentaire est caractérisée selon plusieurs dimensions : disponibilités, conditions d'accès, qualités des aliments, stabilité, mais aussi objectifs sociaux et politiques.
El presente trabajo tiene por objetivo proponer aspectos fundamentales para la adopción tecnológica en el sistema bovino de doble propósito. Esta propuesta plantea que el proceso de innovación tecnológica se inicia con la descripción del objetivo de la unidad de producción y su situación actual, con énfasis en el área que se pretenda aplicar. Enseguida, se debe identificar, correctamente, la necesidad que se pretende resolver y la alternativa tecnológica más pertinente. Cualquiera que sea el factor que detone la necesidad de tecnificación, la inversión realizada debe ser rentable
Although many agronomic researchers currently focus on designing and developing decision support systems, they rarely discuss the methodological implications of such work. In this paper, with the examples of two decision support systems, we propose methodological elements for conducting the participatory design of such tools. The authors proposition aims at building dialogue between designers and users but also between humans, tools and work situations.
The article assesses the influence of the Common Agricultural Policy (CAP) on the pastoral farming systems in a National Park within the south west of England and more recent attempts to use innovative and participatory techniques to reconcile pastoral farming systems with wildlife management. The paper confirms evidence that the economic sustainability of farm businesses in the UK involved in pastoral farming is reducing, and that wildlife-orientated schemes are changing traditional farming systems in a way that might not be in the long-term interest of wildlife
This article investigates determinants and impacts of cooperative organization, using the example of smallholder banana farmers in Kenya. Farmer groups are inclusive of the poor, although wealthier households are more likely to join. Employing propensity score matching, we find positive income effects for active group members. Yet price advantages of collective marketing are small, and high-value market potentials have not yet been tapped. Beyond prices, farmer groups function as important catalysts for innovation adoption through promoting efficient information flows.
Classical innovation adoption models implicitly assume homogenous information flow across farmers, which is often not realistic. As a result, selection bias in adoption parameters may occur. We focus on tissue culture (TC) banana technology that was introduced in Kenya more than 10 years ago. Up till now, adoption rates have remained relatively low.
With the commercialization of agriculture, women are increasingly disadvantaged because of persistent gender disparities in access to productive resources. Farmer collective action that intends to improve smallholder access to markets and technology could potentially accelerate this trend. Here, we use survey data of small-scale banana producers in Kenya to investigate the gender implications of recently established farmer groups. Traditionally, banana has been a women’s crop in Kenya. Our results confirm that the groups contribute to increasing male control over banana.
A group of researchers and industry writers have constructed a narrative of technological triumph for Bt cotton in India, based on an empirical record of superior performance compared to conventional seed. Counterclaims of Bt cotton failure are attributed to mutually reinforcing interactions among non-governmental organisations which avoid rigorous comparisons. However, researchers and the biotechnology industry are also engaged in a similar authentication loop for generating, validating, and publicising such facts.
