Pendant des décennies, la faiblesse des investissements publics dans l’agriculture a laissé les agriculteurs extrêmement vulnérables face à l’instabilité des prix, aux crises climatiques et économiques, et sans moyen pour sortir de la pauvreté. Les bailleurs de fonds et les gouvernements doivent concevoir le soutien à l’agriculture comme partie intégrante de la solution à long terme aux crises alimentaires, financières et climatiques.
Fidèle à sa tradition d’exploration des principales questions émergentes, Nature & Faune a choisi de consacrer cette édition à l’examen de cette urbanisation rapide et de ses conséquences pour les denrées urbaines et la sécurité alimentaire, mettant en exergue les rôles spécifiques de la gestion et de l’utilisation durables des ressources naturelles dans l’évolution rapide de l’alimentation urbaine et de l’équation nutritionnelle en Afrique.
La crise alimentaire mondiale de 2008 a bien évidemment également touché l’Afrique de l’ouest et l’une de ses filières phares : le riz. Cette crise a incité les États et les institutions régionales à mettre en oeuvre des mesures visant à améliorer la production et l’offre locales de riz.
Given the search for new solutions to better prepare cities for the future, in recent years, urban agriculture (UA) has gained in relevance. Within the context of UA, innovative organizational and technical approaches are generated and tested. They can be understood as novelties that begin a potential innovation process. This empirical study is based on 17 qualitative interviews in the U.S. (NYC; Philadelphia, PA, USA; Chicago, IL, USA).
To meet global demands towards food security, safety as well as sustainable agriculture and food systems innovative approaches are inevitable. Despite the growing body of literature in both innovation research and in values and aims, what has been explored to a lesser extent is the bridging link between these areas. This study represents a first step in addressing this relationship.
The process of adopting innovation, especially with regard to precision farming (PF), is inherently complex and social, and influenced by producers, change agents, social norms and organizational pressure. An empirical analysis was conducted among Italian farmers to measure the drivers and clarify “bottlenecks” in the adoption of agricultural innovation. The purpose of this study was to analyze the socio-structural and complexity factors that affect the probability to adopt innovations and the determinants that drive an individual’s decisions.
Although the benefits of genetically modified (GM) crops have been well documented, how do farmers manage the risk of new technology in the early stages of technology adoption has received less attention. We compare the total factor productivity (TFP) of cotton to other major crops (wheat, rice, and corn) in China between 1990 and 2015, showing that the TFP growth of cotton production is significantly different from all other crops. In particular, the TFP of cotton production increased rapidly in the early 1990s then declined slightly around 2000 and rose again.
Familiar mixed dairy sheep farm is the most widespread system in the Mediterranean basin, in Latin America and in developing countries (85%). There is a strong lack of technological adoption in packages of feeding and land use in small-scale farms. To increase competitiveness, it would be of great interest to deepen the knowledge of how innovation was selected, adopted, and spread. The objective of this research was to select strategic feeding and land use technologies in familiar mixed dairy sheep systems and later assess dairy sheep farms in Spain.
Agricultural production systems are a composite of philosophy, adoptability, and careful analysis of risks and rewards. The two dominant typologies include conventional and organics, while biotechnology (GM) and Integrated Pest Management (IPM) represent situational modifiers. We conducted a systematic review to weigh the economic merits—as well as intangibles through an economic lens—of each standalone system and system plus modifier, where applicable. Overall, 17,485 articles were found between ScienceDirect and Google Scholar, with 213 initially screened based on putative relevance.
Este trabajo tiene como objetivo conocer el uso de las TIC por parte de los AF. Se busca dar cuenta del proceso de creación social de la innovación y tecnología, desde una concepción de la complejidad de los procesos de innovación y de comunicación, asumiendo a las TIC como medios de comunicación. Este trabajo sigue el marco teórico de la Innovación, incorporando conceptos de la Teoría de la Comunicación.
