C’est en 1954 que les paysans de la Commune rurale de l’Imanan, située dans l’Ouest du Niger, ont commencé la culture de pomme de terre. Partie d’une simple culture d’appoint associée à d’autres spéculations, la production de pomme de terre fait maintenant partie intégrante des systèmes de productions locaux. C’est la principale stratégie adaptative des paysans pour faire face aux crises alimentaires.
La crise cacaoyère de la fin de la décennie 1970 a profondément bouleversé les stratégies de survie des producteurs. Elle s’est manifestée par la rareté des facteurs de production (la terre et le travail), la diminution de la production et du revenu, la transformation du milieu écologique et la baisse de la pluviométrie. Pour faire face à l’ensemble de ces contraintes, les producteurs ont adopté diverses stratégies dont l’objectif est soit de diversifier les sources de revenu, soit de réduire les charges familiales.
Este trabajo tiene como objetivo general mostrar la relación entre las variables de la cultura organizacional del sistema de empresas de la comunidad indigena de Nuevo San Juan Parangaricutiro, Michoacán y las formas de manejo forestal a través del análisis situacional.
Esta investigación se desarrolló a través de la herramienta metodológica de la malla del Marco Lógico, estableciendo la consistencia en el fenómeno a analizar a través de la construcción del siguiente objeto de estudio: La pequeña organización artesanal de productores de chocolate en Chiapas. Se tomaron en cuenta las dimensiones teóricas (abstractas), producción, cultura y familia, y desde el campo de la investigación científica de los estudios de agronegocios y ciencias económico-administrativas.
Recently, Agricultural Knowledge and Innovation Systems (AKISs) have gained considerable attention in scientific and political forums in the European Union (EU). AKIS is considered a key concept in identifying, analysing and assessing the various actors in the agricultural sector as well as their communication and interaction for innovation processes. Using qualitative expert interviews and organizational mapping, the features of national AKISs were investigated in selected EU member states (Belgium, France, Ireland, Germany, Portugal and the UK).
This article starts by describing the evolution of innovation in agricultural research and cooperation for development, including an historical overview of agricultural research for development from green revolution to the re-discover of traditional knowledge. Then the authors analyze participation in innovation processes and make a comparison of innovation systems and platforms targeting the agri-food sector in developing countries. A particular focus is reserved to the European regional networks and to the experience of the USAID Middle East Water and Livelihoods Initiative.
The innovation of agricultural systems management is a determinant factor that guarantees adaptation to a new paradigm of global economy, environmental protection, and social requirements. The conventional concepts of innovation, applicable to new products and processes, do not consider many characteristics of the agricultural sector, such as social innovation and innovation resulting from new or renewed processes.
In this paper it is assessed the types of knowledge networks utilised by small-scale farmers in four case studies (located in Bulgaria, Poland, Portugal, and the United Kingdom). We focus on knowledge acquired to inform three new activities being undertaken by study participants: agricultural production, subsidy access and regulatory compliance, and farm diversification (specifically agritourism).
Organic farming can play an important role in rural development and food production, by reinforcing the trend toward sustainable agriculture and its purpose of ecosystem conservation. The agribusiness of organic farming is particularly relevant in family farming, given the labor availability and the short marketing circuits. The innovative techniques of organic farming, namely with soil fertility, weed and pest control, opens a wide range of possibilities in its development and extension.
The determination of bunch features that are relevant for bunch weight estimation is an important step in automatic vineyard yield estimation using image analysis. The conversion of 2D image features into mass can be highly dependent on grapevine cultivar, as the bunch morphology varies greatly. This paper aims to explore the relationships between bunch weight and bunch features obtained from image analysis considering a multicultivar approach.
