L’insécurité alimentaire s’intensifie au Québec malgré des interventions gouvernementales qui s’attaquent à divers aspects du problème et font intervenir de nombreux acteurs fédéraux et provinciaux de différentes sphères d’action publique. Ce mémoire s’interroge sur la cohérence des actions publiques au sein de chacun des ordres de gouvernement (cohérence horizontale) et entre ces ordres de gouvernement (cohérence verticale).
La dégradation accrue de la qualité des aliments est l'une des conséquences de l'industrialisation du secteur agricole et de l'agroalimentaire, processus qui a été intensifié par la globalisation et la conséquente ouverture des marchés aux produits étrangers concurrençant et fragilisant les entreprises et les petites fermes agricoles locales. Cet état de fait préoccupe aussi bien les agriculteurs que les consommateurs et n'a pas laissé indifférents les acteurs locaux qui s'investissent désormais pour des produits alimentaires de qualité et de proximité.
This study explores the properties of innovation systems and their contribution to increased eco-efficiency in agriculture. Using aggregate data and econometric methods, the eco-efficiency of 79 countries was computed and a range of factors relating to research, extension, business and policy was examined. Despite data limitations, the analysis produced significant results.
The study focuses on how levels of innovation, measured by complexity and investments requirements of the adopted technologies, relates to innovative behavior and complying with social responsibility practices, as two indicators of the farmer's behavior towards innovation. A typology of farmers with different technological
levels was constructed based on multivariate techniques, according to the adoption of seven technologies. The main objective of the study was to relate SR and innovative behavior to the technology clusters
The aim of the paper is to evaluate the impact of value-webs as an innovation in agricultural production on welfare of cassava smallholders in Nigeria. The estimation procedure involved the alternative process of multivalued treatment models when treatment units have multiple values. The study thus extends previous impact studies which focused on estimating causal effects from binary treatment units. The treatment units were determined from the extent of utilization of cassava which informed the classification of households into value-web groups.
The paper is based on the analysis of cooperation in two different German case studies: One case deals with the development of a sustained value chain for ethical poultry production while the other case aims at the combination of different niche innovations for cultural landscape conservation. The empirical analysis is based on the categories ‘goals of the innovation and motives of cooperation’, ‘actors and their resources’, ‘distribution of costs and benefits’, ‘cooperation structure and management’.
This study examines the price transmission mechanisms in the Bloemfontein beef market using the producer price and retail prices at four retail outlets collected over a period of 3 years. It further estimates the causality links between the producer and retail prices. The traditional (Engle-Granger) and standardized (Enders & Siklos) Augmented Dickey- Fuller procedures were used to test for co-integration and asymmetry in price transmission
The study analyzed the value chain of natural rubber in Nigeria. The study specifically mapped the natural rubber value chain and identify the functions performed by the respondents in the chain; identified the existing marketing channels and estimated the marketing margin at each value addition point. Data for the study were collected using a well-structured questionnaire administered to 425 respondents selected using a two–stage sampling process involving random and purposive sampling techniques
This paper examines innovations for bridging gender gaps in agricultural value chains in Africa. It focuses on innovative platforms for addressing gender gaps, considering women contribute up to 40 percent of labor in agricultural production. Women remain at the bottom of value chains and face gender-specific constraints attributable to gender and social norms, discriminatory beliefs and practices, gender-blind designs and delivery of technologies and innovations which impede women s participation in value chains.
Based on three rounds of panel data (2007, 2009, and 2012) on indigenous households, this study assessed the impacts of Integrated Aquaculture-agriculture value chain participation on the welfare of marginalized poor indigenous rural households in Bangladesh. We also examined the distributional impacts of IAA value chain
