Upscaling agroforestry in the tropics through actor-networks: a comparative case study of cacao farming systems in two regions of Colombia

Agroforestry systems (AFS) upscaling has the potential to integrate sustainability and resilience objectives into agriculture. However, this is a daunting task requiring multi-actor collaboration across public and private sectors at multiple governance levels, coupled with innovative approaches to jointly managing AFS knowledge. Understanding such multi-actor interactions from a network perspective may help to unravel how social structures, created by relational patterns enhance or hinder AFS upscaling. Our paper aims to comparatively explore the role of regional actor-networks on AFS upscaling for a selected farming system. By conducting semi-structured interviews, we collected information about the ties of 86 actors supporting cacao agroforestry systems (CAFS) across two regions of Colombia. We use social network analysis (SNA) to comparatively visualize and understand the general structure of these networks, find relational patterns between the diverse categories of actors involved, and identify a set of key players bridging the majority of the actors within these networks. We find highly centralized networks that connect multiple actors by a low number of mostly non-reciprocal ties. Within these networks, we identify a predominance of bridging ties over bonding ties, homophily patterns among research and education institutions, and heterophily configurations among farmer-based organizations. We also find that the composition of the sets of key actors and the platforms where they converge varies substantially from region to region due to decentralized agricultural policies and differing characteristics across regions. Our approach provides key entry points for promoting multi-actor coalitions that can effectively expand the benefits of AFS in tropical agricultural systems

Analyzing influencing factors to scale up agroforestry systems in Colombia: A comparative ex-ante assessment of cacao farming and cattle ranching in two regions

Agroforestry systems (AFS) are proved to enhance sustainable land management. Thus, there is increasing demand for effective ways to scale up AFS so that more people can benefit. Consequently, this study assesses the scaling-up potential of agroforestry systems (AFS) using cacao farming and cattle ranching in Caqueta and Cesar, Colombia, as examples. An ex-ante assessment using the ScalA tool is conducted through interviews with AFS experts from institutions promoting AFS. Using a comparative approach, results reveal that AFS have different scaling-up potential depending on the type of farming system and location characteristics. In our case, it is slightly higher for cacao farming than for cattle ranching in both regions and it is higher in Caqueta than in Cesar for both systems. Factors hindering the scaling-up potential for both regions are economic conditions at the local and regional levels since there is a lack of stable and differentiated markets to absorb AFS products. In contrast, the scaling-up potential in both regions is increased by the factors related to the capacity of the organizations that promote AFS and the attitudes of local communities toward them. The study generates information about factors that may hinder or foster AFS scaling-up, including not just the capacities and mechanisms to promote them but also the enabling conditions. This contributes to prioritizing AFS interventions and better allocating their resources to increase their chances of successful scaling-up

Mapping research trends in publications related to bio-jet fuel: a scientometric review

It is a fact that society has increased the need for mobility throughout the world. In that regard, it has become aware of the problems associated with the use of fossil fuels such as jet-fuel. As alter-natives, the use of bio-jet fuel has been proposed, which is a biofuel that researchers have evaluated and developed as an environmentally friendly alternative. The development of research on the topic of biofuels has generated a growing number of alternatives in the methods, technologies and raw materials for the production of bio-jet fuel. In this work, a bibliometric study has been developed to analyze the evolution of publications, the contribution of authors, countries, in terms of citation productivity on the topic of bio-jet fuel. Scientific publications were searched in the Scopus database for the period 2001 to 2021. The results showed that the publications have grown exponentially in the last 10 years. The most influential institution and country are from China. “Renewable and Sustainable Energy Reviews” is the most cited journal in the field of bio-jet fuel. The growth rate of publications was estimated using the Gompertz model, the rate was 0.2232 y-1. Most of the documents were published in journals Q1

Friedensförderung in Zeiten von COVID-19: Risikoadaptierte Strategien von Kooperations- und Entwicklungsprojekten

National and international cooperation and development projects (CDP) are fundamental for peacebuilding. However, unforeseen global crises, like COVID-19, can endanger such projects, requiring rapid adaption. In Colombia, the coronavirus outbreak threatens to slow the implementation of peace-related projects, while simultaneously violence over control and ownership of land increases. Although the mid- to long-term consequences for peacebuilding are unknown, exploring risk-adapted strategies of national and international CDP can help identify crucial aspects for future processes and implementations. This study explores the key challenges and coping strategies of implementing agencies and stakeholders to COVID-19, thus helping to derive and improve risk-adapted strategies. After reviewing academic and grey literature, and implementing a semi-structured survey, peacebuilding risked-adapted strategies to COVID-19 are explored with respect to conflict-affected and vulnerable areas of Colombia. Findings show that increasing complexity rooted in top down governmental measures, the rise of new local power relations (e.g. armed groups, illicit activities), and social alienation are negatively affecting peacebuilding in Colombia. Future CDP risk adapted strategies should build on local interests and needs through public-private and environmental cooperation.Nationale und internationale Kooperations- und Entwicklungsprojekte (CDP) sind für die Friedensförderung von grundlegender Bedeutung. Unvorhergesehene globale Krisen, wie COVID-19, können solche Projekte jedoch gefährden und erfordern eine rasche Anpassung. In Kolumbien droht der Ausbruch des Coronavirus die Durchführung friedensbezogener Projekte zu verlangsamen, während gleichzeitig die Gewalt über die Kontrolle und den Besitz von Land zunimmt. Obwohl die mittel- bis langfristigen Folgen für die Friedenskonsolidierung unbekannt sind, kann die Untersuchung risikoangepasster Strategien des nationalen und internationalen CDP dazu beitragen, entscheidende Aspekte für künftige Prozesse und Implementierungen zu ermitteln. Diese Studie untersucht die Herausforderungen und Bewältigungsstrategien der Durchführungsorganisationen und Interessengruppen im Kontext von COVID-19, umso risikoangepasste Strategien abzuleiten und zu verbessern. Basierend auf Literaturrecherche und der Durchführung semi-strukturierter Interviews werden risikoangepasste Strategien der Friedensförderung für COVID-19 in unterschiedlichen Teilen Kolumbiens untersucht. Die Ergebnisse zeigen, dass die zunehmende Komplexität, die in den Maßnahmen der Regierung von oben nach unten, dem Entstehen neuer lokaler Machtverhältnisse (z. B. bewaffnete Gruppen, illegale Aktivitäten) und in zunehmend sozialer Entfremdung wurzelt, die Friedensförderung in Kolumbien negativ beeinflusst. Künftige risikoangepasste Strategien des CDP sollten auf lokalen Interessen und Bedürfnissen durch öffentlich-private und umweltpolitische Zusammenarbeit aufbauen.Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF) e.V.

El Uso de los Smartphones y las relaciones interpersonales de los jóvenes universitarios en la ciudad de Barranquilla

Objetivo: Analizar la relación entre el uso de los Smartphones y las relaciones interpersonales de estudiantes universitarios en la ciudad de Barranquilla. Materiales y métodos: Estudio descriptivo transversal mediante encuesta anónima a 400 estudiantes en una universidad privada, seleccionados aleatoriamente. Variables estudiadas: frecuencia de revisión de mensajes y llamadas, conflicto en las relaciones con padres, amigos y pareja y el distanciamiento en las relaciones, generado por el uso de excesivo del móvil. El conflicto en las relaciones se relacionó con las variables socio-demográficas y el perfil de uso de los Smartphones. Resultados El 80% estaba suscrito a un plan de datos, el 53% revisaba su Smartphone cada 15 minutos o menos, el 66% lo lleva a todas partes y el 52% lo usaba en exceso. Las dos razones de uso más frecuentes fueron: mantenerse en contacto/diversión (22%), seguido de mantenerse en contacto/estudio (12.5%). Las mujeres usaban más el celular y tenían más conflictos en sus relaciones que los hombres, debido al uso excesivo; además, se sentían más molestas/desplazadas, cuando su interlocutor usaba el móvil en su presencia. La principal razón de conflictos por el uso del Smartphone en la relación con otras personas fue la distracción. Conclusiones Los usuarios, en general, consideran que los Smartphones afectan positivamente sus relaciones, aunque ocurran conflictos. Hay diferencias por sexo con respecto a la presentación de conflictos por su uso excesivo, predominante en las mujeres, quienes tienden a tolerar menos que éste sea utilizado en su presencia
