Innovation system approach offers an holistic, multidisciplinary and comprehensive framework for analyzing innovation process, the roles of science and technology actors and their interactions, emphazing on wider stakeholder participation, linkages and institutional context of innovation and processes. This paper was aimed to: 1. review the concept of innovation system; 2. appraise the application to agriculture and its relevance and 3. analyze the policy implications for agricultural extension delivery in Nigeria.
This study introduces a framework for managing information flow in innovation systems. An organisation's capacity to receive information, to share it with others and to learn from it is assumed to be the key factor that shapes the flow patterns and, hence, the performance of the innovation system concerned. The framework is applied to characterise the information structure underlying the agricultural innovation system of Azerbaijan and to develop an information strategy for the system to accelerate the information flow.
This study examines the role of public–private partnerships in international agricultural research. It is intended to provide policymakers, researchers, and business decisionmakers with an understanding of how such partnerships operate, how they promote the exchange of knowledge and technology, and how they contribute to poverty reduction.
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.
Au sud-est de la commune de Djougou, les eaux de surface à usage pastoral se raréfient depuis les années 1990. Pour en comprendre l’ampleur et les raisons, nous avons développé un outil permettant une analyse socio-spatiale et socio-environnementale, à l’échelle du finage de deux villages, des dynamiques des ressources, de leurs usages et des stratégies d’accès développées par les populations : un SIG « à dires d’acteurs » associant sur le même support une cartographie classique (réseau hydrographique, forêts, voies de communication, villages, etc.) et l’expertise des populations locales.
This study examined the trend in climate in Ghana, how smallholder horticultural farmers perceive this changing climate and how they are responding to its perceived effects. A survey of 480 resource-constrained horticultural producers was conducted in two municipalities of Ghana. Descriptive analysis and Weighted Average Index were employed to rank identified adaptation strategies and challenges. The results showed that farmers are already experiencing increasing temperature and declining rainfall patterns consistent with trends of observed climate changing in the last two decades.
The Fiji Islands, like many small Pacific island nations, are thought to incur high rates of postharvest loss. Little work has been undertaken to quantify the amount of loss within Pacific horticultural value chains, or identify the key determinants. This study sought to quantify postharvest loss within Fijian smallholder tomato value chains and to examine the relative importance of current on-farm practices as possible contributors to this loss.
Existing studies which have examined the impact of group farming on farm productivity have focused predominantly on former socialist regimes, usually comparing production under various types of collectivised/cooperatized farms with farm enterprises that emerged in the post-reform period, or after decollectivisation. Given this specificity, their experience is at best indicative; it cannot provide substantive lessons on the potential outcomes of group farming in today’s developing countries. This paper seeks to do so.
The paper makes significant contribution to the body of literature on the possible role of adaptation by farmers in Ghana particularly the fragile savannah ecological zone. The study explored smallholder farmers' responses to climate and ecological change effects on their livelihood activities that have emerged since the mid-1980s within the savanna agro ecological zone of Northern Ghana using an ethnographic approach.
This paper proposes the adoption of small-scale friendly postharvest techniques in the form of small-scale postharvest practices (SSPPs). To justify this proposal, the impact of SSPPs adoption on self-reported losses were investigated in Rivers State Nigeria. The factors influencing plantain farmers and traders intention to use SSPPs were also studied. Multistage and snowball sampling techniques were used to obtain data from farmers and traders, respectively
