ArticleJournal articleLa construcción del corredor verde de Mendebaldea: soluciones basadas en la naturaleza para la recuperación de suelos en Vitoria-Gasteiz (España). El caso del proyecto Phy2Sudoe

No results found.Al oeste de Vitoria-Gasteiz se desarrollaron en las últimas décadas zonas industriales y de transporte que, por su rápido crecimiento, provocaron fragmentación y fragilidad ecológica en el territorio. La zona de trabajo (unas 30 Ha.) pese a haber sido planificada como zona verde se encontraba al inicio del proyecto en estado de abandono y con suelos contaminados que impedían el uso público y cualquier actividad.Desde el Ayuntamiento de Vitoria-Gasteiz, en colaboración con la Universidad del País Vasco, el Centro de Investigación Neiker-Tecnalia y departamentos municipales de gestión de residuos, se propuso la restauración del ámbito mediante el empleo de soluciones basadas en la naturaleza para crear una gran infraestructura verde que aportase diversos beneficios ambientales, como la mitigación del cambio climático, la recuperación de los suelos y la mejora del paisaje.El trabajo se desarrolló en 3 fases (10 hectáreas restauradas cada 2 años durante 6 años) incluyendo varias acciones: instalación de un bosque sumidero de carbono, fijación de C en el suelo mediante enmiendas orgánicas, promoción de la biodiversidad con balsas artificiales, uso de filtros verdes para aguas y creación de una red de caminos para el uso público. Para la descontaminación de suelos se recurrió a la fitorremediación (combinación enmiendas, cultivos forestales y sistemas agroforestales) mediante la participación con otros socios investigadores del sur de Europa en el proyecto PhytoSudoe y Phy2Sudoe que colaboraron en el diseño, estrategia, implementación y seguimiento de las técnicas fitorremediadoras.La recuperación del suelo está siendo monitorizada por los socios del proyecto y las parcelas de ensayo sirven además como espacio demostrativo para el aprendizaje de estudiantes y técnicos mediante visitas guiadas y prácticas. Se incluyó un programa de ciencia ciudadana para contar con la participación del público en el seguimiento de la recuperación de los suelos.Palabras clave: Cambio climático, Gestión del paisaje, Fitorremediación, Investigación, Seguimiento y recopilación de datosID: 3623736 -

Book (stand-alone)Manual / guideProcessing of fresh-cut tropical fruits and vegetables: A technical guide 2010
Also available in:
No results found.There has been a marked upward trend in production and consumption of fruits and vegetables in Asia and the Pacific in recent years. Along with rising consumer demand has come greater awareness of food safety issues and increased need for convenience and quality. Selection of high quality horticultural produce for processing and implementation of good practices during processing operations are required to assure both the quality of the produce and the safety of the final product. This technical guide reviews, from a theoretical and practical perspective, the critical issues that must be addressed for fresh-cut produce to meet consumer demand for convenience, quality and safety. A case study on fresh-cut processing in Thailand is included. The guide should be of practical value to small processors, trainers and extension workers who provide support to individuals engaged in production of fresh-cut tropical produce for sale. -
Book (series)FlagshipThe State of Food and Agriculture 2019
Moving forward on food loss and waste reduction
2019The need to reduce food loss and waste is firmly embedded in the 2030 Agenda for Sustainable Development. Food loss and waste reduction is considered important for improving food security and nutrition, promoting environmental sustainability and lowering production costs. However, efforts to reduce food loss and waste will only be effective if informed by a solid understanding of the problem. This report provides new estimates of the percentage of the world’s food lost from production up to the retail level. The report also finds a vast diversity in existing estimates of losses, even for the same commodities and for the same stages in the supply chain. Clearly identifying and understanding critical loss points in specific supply chains – where considerable potential exists for reducing food losses – is crucial to deciding on appropriate measures. The report provides some guiding principles for interventions based on the objectives being pursued through food loss and waste reductions, be they in improved economic efficiency, food security and nutrition, or environmental sustainability. -
Book (series)Technical studyThe impact of climate variability and extremes on agriculture and food security - An analysis of the evidence and case studies
Background paper for The State of Food Security and Nutrition in the World 2018
2020Also available in:
No results found.Global climate studies show that not only temperatures are increasing and precipitation levels are becoming more varied, all projections indicate these trends will continue. It is therefore imperative that we understand changes in climate over agricultural areas and their impacts on agriculture production and food security. This study presents new analysis on the impact of changing climate on agriculture and food security, by examining the evidence on recent climate variability and extremes over agricultural areas and the impact of these on agriculture and food security. It shows that more countries are exposed to increasing climate variability and extremes and the frequency (the number of years exposed in a five-year period) and intensity (the number of types of climate extremes in a five-year period) of exposure over agricultural areas have increased. The findings of this study are compelling and bring urgency to the fact that climate variability and extremes are proliferating and intensifying and are contributing to a rise in global hunger. The world’s 2.5 billion small-scale farmers, herders, fishers, and forest-dependent people, who derive their food and income from renewable natural resources, are most at risk and affected. Actions to strengthen the resilience of livelihoods and food systems to climate variability and extremes urgently need to be scaled up and accelerated.
