Applying the principles of transformative innovation, strengthens agroecological transition processes The sustainable transformation of agri-food systems through the application of agroecological principles can help to mitigate the effects of the food crisis triggered by the health emergency and the subsequent economic recession. Accordingly, the aim of this reflection research article is to reflect on the correspondence of the principles of transformative innovation (TI) with the agroecological approach and how its application favours the processes of generation, diffusion and adoption of agroecological innovations. It is currently recognised that overcoming social and environmental challenges can contribute to economic growth and competitiveness in the long term, which becomes the basis of TI policies aimed at the generation, diffusion and adaptation of environmental and social innovations, framed within the achievement of the SDGs. At the territorial level, innovations conceived from a sectoral approach can limit the analysis of the contribution of science, technology and innovation in solving social problems. Therefore, especially in rural areas, the application of IT principles can help support agroecological transition processes, which allow addressing social, economic, political and environmental challenges.

Biogeographical distribution, conservation and local use of Amburana acreana (Ducke) A. C. Sm. in the Cacoal-Rondônia region, Brazil Amburana acreana (Ducke) A. C. Sm., popularly known as "cerejeira" or emburana, is a tree belonging to the Fabaceae family (Leguminosae: Faboideae) and is included in the list of threatened and endangered species, according to Regulation No. 06 of the Brazilian Ministry of the Environment, dated 23 September 2008, standing out as one of the most vulnerable species. The objective of this study was to analyse the biogeographic distribution of A. acreana in the municipality of Cacoal, located in the Brazilian Amazon. The research was based on field data, complemented by herbarium records, databases, sampling and surveys of the local community to obtain information on the location and abundance of the species. The use of advanced tools such as DIVA-GIS 7.5® and Terra-i® made it possible to visualise the distribution of A. acreana in Brazil, both in its natural habitat (States of Acre, Mato Grosso and Rondônia) and in cultivated areas (Minas Gerais and Rio de Janeiro), extending also to Bolivia and Peru. In the municipality of Cacoal, the presence of the species was confirmed in ten localities, two of which hosted more than six adult individuals. The consideration of the microclimatic conditions of these localities proves to be a crucial element for proposing effective conservation strategies. The study not only provides a detailed overview of the distribution of A. acreana, but also highlights the need to address specific environmental conditions to ensure the long-term conservation of this threatened species in the Amazon region.

Dos conquistas más, camino a más indexaciones Después de  haber sido incluida en el catálogo 2.0 de Latindex  y en el Directorio  de  Revistas  de  Acceso Abierto  (DOAJ),  Magna  Scientia  UCEVA  logra  dos nuevas indexaciones en importantes índices: MIAR, la Matriz de Información para el Análisis de Revistas, un sistema desarrollado por la Universidad de Barcelona en  España  desde  2004,  que  evalúa  la  calidad  de  las publicaciones   científicas   mediante   el   cálculo   del Índice Compuesto de Difusión Científica (ICDS). Este índice  valora  la  presencia  de  las  revistas  en  bases  de datos    de    citas,    tanto    multidisciplinarias    como especializadas, reflejando así su alcance internacional. La última inclusión del año 2023 es ASCI (Índice de Citación  Científica  Asiática),  una  base  de  datos  que emplea  criterios  rigurosos  para  seleccionar  revistas, garantizando su calidad y relevancia académica. Estos criterios    incluyen    procesos    editoriales    sólidos, contenido   original   y   significativo,   claridad   en   el enfoque  temático,  frecuencia  regular  de  publicación, diversidad  global  de  autores,  adhesión  a  estándares éticos y una notable influencia en la citación. Con estas nuevas  indexaciones,  la  UCEVA  como  entidad  editora fortalece   su   presencia   a   nivel   internacional   y  se prepara para alcanzar objetivos más ambiciosos en su camino  hacia  la  indexación  en  plataformas  como Redalyc, SciELO y Scopus.

Seedling competition between Pennisetum setaceum (Poaceae) and three native weeds of La Primavera wood, Guadalajara, Jalisco (México) Pennisetum setaceum (Forssk.) Chiov., 1923 is an exotic grass from the Arabian Peninsula that has been very successful as an ornamental plant worldwide in recent years. Unfortunately, it has proved to be a very competitive invader, causing ecological problems in several regions of the world. We don't know exactly how this species interacts with native weeds in Mexico. Our study aims to show the interactions of Pennisetum with three species of native weeds in the surroundings of the metropolitan area of Guadalajara, Jalisco, Mexico: Aeschynomene villosa var. longifolia (Micheli) Rudd, Desmodium aparines (Link) DC. and Paspalum notatum (Flüggé). The seeds of Pennisetum were tested in monospecific groups (competing against itself) and in association with each of the native species mentioned and with a treatment together with all the compound of the species mentioned, thus simulating what could happen in natural conditions upon the arrival of the seeds of P. setaceum in a degraded soil of Guadalajara. The results show how the biomass produced and the speed of growth of Pennisetum can be a real alarm for the conservation of local germplasm.
