El resultado de un análisis de la cadena de valor en el sector agrícola son insumos para formular y establecer políticas de desarrollo rural, más aún cuando la intermediación hace que el flujo de mercancías sea extenso y se producen sobre precios lo que resta competencia y valor a los productos agrícolas.
In this paper it is reviewed the literature on how transitions to sustainable food systems may play out and present a framework based on the Multi-Level Perspective on Socio-Technical Transitions, which builds upon conceptual developments from social and natural science disciplines.
Intermediary actors have been proposed as key catalysts that speed up change towards more sustainable socio-technical systems. Research on this topic has gradually gained traction since 2009, but has been complicated by the inconsistency regarding what intermediaries are in the context of such transitions and which activities they focus on, or should focus on. This study briefly elaborates on the conceptual foundations of the studies of intermediaries in transitions, and how intermediaries have been connected to different transition theories.
The shrimp sector has been one of the fastest growing agri-food systems in the last decades, but its growth has entailed negative social and environmental impacts. Sustainable intensification will require innovation in multiple elements of the shrimp production system and its value chain. The study focuses on the case of the shrimp sector in the Mekong Delta in Viet nam to explore the constraints inthe transition to sustainable intensification in shrimp farming, using an analytical framework based on innovation systems thinking, i.e., an aquaculture innovation systems framework.
Although an agro-based country, the farmers of Bangladesh do not receive significant returns from their products, due to some obstacles blocking the achievement of this ultimate goal. This study tries to identify the major challenges of the agroforestry product supply chains in Bangladesh, and offer an alternative solution through the involvement and experiences of farmer cooperatives within a Japanese cooperative model.
Nutrition and Agriculture are interlinked with each other. Sustainable agricultural development is agricultural development that contributes to improving resource efficiency, strengthening resilience and securing social equity/responsibility of agriculture and food systems in order to ensure food security and nutrition for all, now and in the future. While poverty has always been associated with severe forms of acute under-nutrition, it is fact that poverty affects an individual’s health throughout their lifetime.
Much of fish consumed by the poor are caught by household members and traded in local markets. These fish are rarely or poorly included in national statistics, and it is therefore difficult to estimate precisely the real contribution of fish to the rural poor households. This report is the first global overview of the role played by fish in improving nutrition. Fish consumption patterns of the poor, the nutritional value of fish, and small-scale fisheries and aquaculture activities are considered. It also highlights the gap in knowledge where more research is needed.
Undernutrition and low dietary diversity remain big problems in many developing countries. A large proportionof the people affected are smallholder farmers. Hence, it is often assumed that further diversifying small-farmproduction would be a good strategy to improve nutrition, but the evidence is mixed. We systematically reviewstudies that have analyzed associations between production diversity, dietary diversity, and nutrition insmallholder households and provide a meta-analysis of estimated effects.
La présente note a pour objet de donner des éléments aux décideurs, au niveau national, pour leur permettre de procéder à des évaluations et de prendre les mesures voulues concernant la sécurité alimentaire et la nutrition face au changement climatique. Elle comprend des informations générales sur l’effet que le changement climatique et la variabilité du climat ont sur les secteurs de l’agriculture et la sécurité alimentaire et la nutrition et sur la façon dont ces secteurs et les habitudes alimentaires contribuent aux émissions de gaz à effet de serre.
Recent research has analyzed whether higher levels of farm production diversity contribute to improved diets in smallholder farm households. We add to this literature by using and comparing different indicators, thus helping to better understand some of the underlying linkages. The analysis builds on data from Indonesia, Kenya, and Uganda. On the consumption side, we used 7-day food recall data to calculate various dietary indicators, such as dietary diversity scores, consumed quantities of fruits and vegetables, calories and micronutrients, and measures of nutritional adequacy.
