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.
Une analyse de trajectoires d’innovations agricoles au Bénin observées dans la longue durée permet d’en identifier les facteurs de diffusion à grande échelle. Beaucoup d’innovations passent inaperçues sur de longs tronçons de leur trajectoire, étant endogènes ou impliquant des acteurs non « conventionnels » et pas d’organisations de recherche. Les innovations qui passent à grande échelle sont en fait des faisceaux d’innovations technologiques, institutionnelles ou organisationnelles qui s’enchaînent les unes en réponse aux contraintes des autres.
Depuis sa création, le Parc national du Mont Péko est sujet à diverses pressions anthropiques. Ces pressions ont été accentuées durant les conflits armés en Côte d’Ivoire entre 2002 et 2011. L’intensification des pressions aurait entraîné une augmentation du taux de déforestation dans le parc. Pour vérifier cette hypothèse, la présente étude visait à déterminer l’effet des conflits sur la dynamique forestière du parc. À cet effet, quatre images satellitaires Landsat ont été analysées pour examiner les changements d’occupation des sols avant, pendant et après les conflits.
This paper uses household and key informant survey data from Ethiopia to: (1) understand the organizational structures that influence change in dairy production systems; (2) explore how local-level innovation system networks are functioning in the smallholder dairy production and (3) identify intervention points for strengthening innovation capacity. Results revealed that public sector actors are the major role players in the dairy production system despite their minor role in marketing linkages. We also found out that the private sector actors play peripheral roles in the network.
This paper draws lessons from selected country experiences of adaptation and innovation in pursuit of food security goals.
In sub-Saharan Africa, there is increasing interest for the adaptation and use of the innovation systems approach to advance learning and development in the Agricultural Research and Development (ARD) sector. This crave is constrained by unavailability of a proven blue print that describe the paradigm shift from the linear approach and how such could function under different socio-economic, cultural and political climate.
Parasitic weeds such as Striga spp and Rhamphicarpa fistulosa in smallholder rice production systems form an increasing problem for food and income security in sub-Saharan Africa. In this paper we implement the Rapid Appraisal of Agricultural Innovation Systems (RAAIS) as a diagnostic tool to identify specific and generic entry points for innovations to address parasitic weeds in rain-fed rice production in Tanzania. Data were gathered across three study sites in Tanzania where parasitic weeds are eminent (Kyela, Songea Rural and Morogoro Rural districts).
There are divergent views on what capacity development might mean in relation to agricultural biotechnology. The core of this debate is whether this should involve the development of human capital and research infrastructure, or whether it should encompass a wider range of activities which also include developing the capacity to use knowledge productively. This paper uses the innovation systems concept to shed light on this discussion, arguing that it is innovation capacity rather than science and technology capacity that has to be developed.
Agricultural policy formulation in Sub Saharan Africa has been dominated by research initiatives that alienated other farmers and stakeholders. The Sub Saharan Africa Challenge Programme (SSA CP) seeks to use multi-stakeholder partnerships as an institutional innovation for agricultural policy formulation and development. This paper uses some experiences from the SSA CP to discuss the design principles for an effective partnership that can deliver relevant agricultural policies.
The purpose of this article is to investigate effective reformism: strategies that innovation networks deploy to create changes in their environment in order to establish a more conducive context for the realization and durable embedding of their innovation projects. Using a case study approach, effective reformism efforts are analyzed in a technological innovation trajectory related to the implementation of a new poultry husbandry system and an organizational innovation trajectory concerning new ways of co-operation among individual farms to establish economies of scale.
