Atlas de las praderas marinas de España

Knowledge of the distribution and extent of seagrass habitats is currently the basis of management and conservation policies of the coastal zones in most European countries. This basic information is being requested through European directives for the establishment of monitoring programmes and the implementation of specific actions to preserve the marine environment. In addition, this information is crucial for the quantification of the ecological importance usually attributed to seagrass habitats due to, for instance, their involvement in biogeochemical cycles, marine biodiversity and quality of coastal waters or global carbon budgets. The seagrass atlas of Spain represents a huge collective effort performed by 84 authors across 30 Spanish institutions largely involved in the scientific research, management and conservation of seagrass habitats during the last three decades. They have contributed to the availability of the most precise and realistic seagrass maps for each region of the Spanish coast which have been integrated in a GIS to obtain the distribution and area of each seagrass species. Most of this information has independently originated at a regional level by regional governments, universities and public research organisations, which explain the elevated heterogeneity in criteria, scales, methods and objectives of the available information. On this basis, seagrass habitats in Spain occupy a total surface of 1,541,63 km2, 89% of which is concentrated in the Mediterranean regions; the rest is present in sheltered estuarine areas of the Atlantic peninsular regions and in the open coastal waters of the Canary Islands, which represents 50% of the Atlantic meadows. Of this surface, 71.5% corresponds to Posidonia oceanica, 19.5% to Cymodocea nodosa, 3.1% to Zostera noltii (=Nanozostera noltii), 0.3% to Zostera marina and 1.2% to Halophila decipiens. Species distribution maps are presented (including Ruppia spp.), together with maps of the main impacts and pressures that has affected or threatened their conservation status, as well as the management tools established for their protection and conservation. Despite this considerable effort, and the fact that Spain has mapped wide shelf areas, the information available is still incomplete and with weak precision in many regions, which will require an investment of major effort in the near future to complete the whole picture and respond to demands of EU directives.Versión del edito

Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Red española de colecciones de judías

7 páginas, 3 tablas.- Trabajo presentado a las III Jornadas de la Asociación Española de Leguminosas y IV Seminario de Judía de la Península Ibérica, celebradas en Valladolid, entre el 2 y el 4 de Septiembre de 2008.La judía común (Phaseolus vulgaris L.) ha sido domesticada en Latinoamérica, siendo incorporada a la agricultura española en el siglo XVI. En España se ha constatado la presencia de una amplia diversidad en la especie a nivel morfológico y molecular (Puerta Romero, 1961; Santalla et al, 2002), consecuencia tanto de sucesivas introducciones como de la adaptación a las condiciones locales de cultivo y selección por parte de los agricultores. El Centro Nacional de Recursos Fitogenéticos (CRF-INIA, Alcalá de Henares, Madrid) es el responsable del mantenimiento del Inventario Nacional y de la conservación de la colección base de semillas ortodoxas de la Red Española de Recursos Fitogenéticos (O.M. de 23 de Abril de 1993; BOE del 7/05/1993). Así mismo, el CRF dispone de una colección activa en diferentes especies, principalmente cereales de invierno y leguminosas grano, entre las que se incluye la judía común. La conservación de colecciones activas implica el establecimiento de unas condiciones que permitan su uso e intercambio; esta situación se traduce en que de cada entrada tiene que conservarse un número suficiente de semillas con un mínimo de viabilidad. En función de estos requisitos, se considera que una muestra está disponible para su intercambio cuando se conservan al menos 1500 semillas, con una germinación igual o superior al 85% [...]Estos trabajos han sido financiados por los proyectos RF95-008-C4-2, RF99-003-C5-2, RF2003-008-C4 y RF2007-00014-C4 del Programa Nacional sobre Conservación y Utilización de Recursos Fitogenéticos del INIA-MCI.Peer reviewe

Percepciones del Desarrollo, dentro y fuera del continente africano

Departing from Sandra Wallman's edited book, Perceptions of Development (Cambridge University Press, 1977), authors emphasize the relevance of documenting and analyzing contexts, discourses and practices of development, especially within the field of International Cooperation (Programs, Plans, Projects), and most certainly in Development Studies. Thus people have agency and respond to economic and social change by organizing themselves, resisting, mobilizing and so on. The concept "perceptions of development" (Wallman, 1977) helps to clarify and contextualize local discourses and practices of development, quite often ignored by policy makers and technicians working in Africa and beyond.AFRICAInEs - Investigación y Estudios Aplicados al Desarrollo (SEJ-491), Departamento de Antropología Social, Universidad de Granada

Participation in and gains from traditional vegetable value chains: A gendered analysis of perceptions of labour, income and expenditure in producers’ and traders’ households

Horticulture is one of the fastest growing subsectors of agriculture in Tanzania. Gender relations in vegetable-producing and vegetable-trading households need to be understood to make value chain development equitable. This study, carried out in northern and central Tanzania, is based on data from surveys, focus group discussions and semi-structured interviews. The perceptions of men and women traders and producers are investigated with regard to labour participation in traditional vegetable value chains and gains (income and expenditure) from it. Farmers were found to report more balanced intra-household labour arrangements paired with less-balanced income and expenditure shares, while traders indicated less-balanced labour contributions that went hand in hand with more-balanced shares of benefits. Farmers related limited household development not only to imbalances in benefits but also to a lack of trust and cooperation between spouses. The importance of gender-transformative approaches in agricultural value chains is emphasized herein
