Southward re-distribution of tropical tuna fisheries activity can be explained by technological and management change

There is broad evidence of climate change causing shifts in fish distribution worldwide, but less is known about the response of fisheries to these changes. Responses to climate-driven shifts in a fishery may be constrained by existing management or institutional arrangements and technological settings. In order to understand how fisheries are responding to ocean warming, we investigate purse seine fleets targeting tropical tunas in the east Atlantic Ocean using effort and sea surface temperature anomaly (SSTA) data from 1991 to 2017. An analysis of the spatial change in effort using a centre of gravity approach and empirical orthogonal functions is used to assess the spatiotemporal changes in effort anomalies and investigate links to SSTA. Both analyses indicate that effort shifts southward from the equator, while no clear pattern is seen northward from the equator. Random forest models show that while technology and institutional settings better explain total effort, SSTA is playing a role when explaining the spatiotemporal changes of effort, together with management and international agreements. These results show the potential of management to minimize the impacts of climate change on fisheries activity. Our results provide guidance for improved understanding about how climate, management and governance interact in tropical tuna fisheries, with methods that are replicable and transferable. Future actions should take into account all these elements in order to plan successful adaptation. © 2020 The Authors.

Estudio del caso EHUsaludable: el virus de un blog para comunicar en la comunidad universitaria de la UPV/EHU

Propósito: La Universidad del País Vasco/Euskal Herriko Unibertsitatea (UPV/EHU), es la única universidad pública en la Comunidad Autónoma Vasca y como tal le corresponde el liderazgo en cuestiones de formación en Salud Pública. Pero más allá de lo sanitario, nuestro enfoque holístico, implica transversalizar la promoción de lo “saludable” a todas las áreas de actividad y a todas las personas miembros de la comunidad universitaria. Se presenta esta experiencia en la UPV/EHU, denominada EHUsaludable, en la que es fundamental el uso del blog corporativo y las aportaciones de los pares, para la implementación de una estrategia comunicativa creando un medio de comunicación propio, con el doble objetivo de aprender hacia adentro y de difundir hacia afuera y viralizar la transversalización de sus objetivos. Material y método: Se presenta la experiencia iniciada en 2016 que identificó los focos donde ya existen iniciativas de trabajo o áreas de conocimiento donde se incluye el enfoque de “lo saludable” y a las personas referente o nodales en dichos ámbitos, para la preparación de un “Diagnóstico 0 de la Promoción de la Salud en la UPV/EHU”. Resultados: Se detectó una gran cantidad de actividades dispersas y desconectadas, así como la necesidad de coordinación entre las personas nodales dentro de la comunidad universitaria para organizar una apuesta común para la transversalización de “lo saludable” en la Universidad. Este estudio de caso sirve para mostrar las claves del éxito y del fracaso en este tipo de experiencias implementadas de abajo a arriba. Conclusiones: La gestión del know-how invisibilizado de las personas es la clave de esta experiencia, y por ello se plantea que la estrategia de comunicación interna, durante todo el proceso de coordinación, corre en paralelo a la realización del “Diagnóstico 0”, a su (futura) difusión y a todas las actividades que se pongan en marcha
