Recycling urban waste as possible use for rooftop vegetable garden

Urban authorities in Europe are confronted with increasing demands by urban dwellers for allotment gardens, but vacant urban soil tends to be scarce and/or polluted by past industrial activities. A possible solution for local authorities could therefore be to promote rooftop gardening. However little technical information exists on certain forms of rooftop urban agriculture, called Z-Farming. In 2012, a pilot experiment was run in Paris (France). Simple and cheap systems of rooftop gardening were tested on a rooftop using as crop substrates only local urban organic waste so as to contribute to the urban metabolism. Production levels and heavy metal contents in cropping substrates and edible vegetables were measured. Available results show (i) high levels of crop production with limited inputs compared to land professional gardening, (ii) low levels of heavy metal pollutants in the edible parts of the crops, especially for Cd and Pb with respect to EU norms for vegetables and (iii) positive influence on yields on organizing the substrate in layers and enhancing the biological activity through earthworm inoculation. These encouraging results allow us to consider that rooftop gardening is feasible and seem to have a great potential to improve urban resiliency. It will nevertheless be necessary to identify more precisely the types of roof that can be used and to assess more fully the generic result of the low level of pollution, as well as the global sustainability of these cropping systems.

The giant's garden.

Forma parte de una serie de lectura para niños en doce niveles diferentes divididos en historias que todavía están relacionadas con las experiencias de los alumnos y, por tanto, despiertan el interés por la lectura. En este nivel ya se han introducido historias más complejas como ésta de fantasía que trata sobre un gigante que tiene un jardín y al que no le gusta que los niños vayan a jugar en él. Cada cuatro páginas hay juegos de palabras, crucigramas, verdadero-falso y preguntas de selección múltiple para reforzarla comprensión del texto.

The monster garden.

Una historia actual que explora las relaciones sociales y las cuestiones relativas a las futuras orientaciones en la experimentación científica. La cuestión de confianza se plantea también como un factor clave. Frankie Stein vive con su hermano, David, y su papá. Su padre es un ingeniero genético que investiga en un gran laboratorio en lo alto de la colina. El laboratorio cuenta con un montón de guardias de seguridad y se parece algo a una de esas viejas películas de horror. Sus compañeros se burlan de ella y dicen que su padre está creando un mundo de monstruos. El padre está siempre demasiado ocupado para hablar y ella comienza a preguntarse si realmente está trabajando por el bien de la humanidad. Un día, David roba un tubo de ensayo del laboratorio. Él y Frankie deciden repartirlo entre ellos y hacer algunos experimentos en secreto. Frankie acaba por producir una encantadora, alegre criatura llamada Monnie, que le gusta silbar y es experta en mutarse. Al instante Monnie se convierte en su mejor amiga y Frankie comienza a sentirse importante y valiosa casi por primera vez en toda su vida. Frankie no quiere renunciar a Monnie pero Monnie es sólo una extraña creación de un tubo de ensayo.

Food and garden waste?

Este recurso presenta a los jóvenes de una manera muy visual, la idea del proceso de reciclaje de los residuos orgánicos: los desperdicios de los alimentos y los residuos de jardinería. Conduce al lector en un viaje para la localización de los residuos, y cómo son reciclados, desde el principio hasta el acabado del nuevo producto. Incluye: fotografías del proceso del reciclaje; datos y cifras del reciclaje; consejos y actividades de diversión. Tiene glosario, bibliografía y sitios web.

The domestic garden: its contribution to urban green infrastructure

Domestic gardens provide a significant component of urban green infrastructure but their relative contribution to eco-system service provision remains largely un-quantified. ‘Green infrastructure’ itself is often ill-defined, posing problems for planners to ascertain what types of green infrastructure provide greatest benefit and under what circumstances. Within this context the relative merits of gardens are unclear; however, at a time of greater urbanization where private gardens are increasingly seen as a ‘luxury’, it is important to define their role precisely. Hence, the nature of this review is to interpret existing information pertaining to gardens /gardening per se, identify where they may have a unique role to play and to highlight where further research is warranted. The review suggests that there are significant differences in both form and management of domestic gardens which radically influence the benefits. Nevertheless, gardens can play a strong role in improving the environmental impact of the domestic curtilage, e.g. by insulating houses against temperature extremes they can reduce domestic energy use. Gardens also improve localized air cooling, help mitigate flooding and provide a haven for wildlife. Less favourable aspects include contributions of gardens and gardening to greenhouse gas emissions, misuse of fertilizers and pesticides, and introduction of alien plant species. Due to the close proximity to the home and hence accessibility for many, possibly the greatest benefit of the domestic garden is on human health and well-being, but further work is required to define this clearly within the wider context of green infrastructure.

The effectiveness of botanic garden collections in supporting plant conservation: a European case study

Europe has the greatest concentration of botanic gardens in the world, they cultivate extensive collections of plants that include samples of European threatened plant species. This study looks at the effectiveness of these collections in supporting species conservation. A three part study is presented: (1) the results of a survey and assessment of threatened plants in botanic gardens, as defined by the Bern Convention; (2) case studies illustrating current issues in the ex situ management of European threatened plant species; and (3) presentation of policy recommendations on further improving botanic garden contributions to European plant conservation. The survey indicated that of 119 European botanic gardens in 29 European countries, 105 are cultivating 308 of the 573 threatened plant species listed by the Bern Convention. The survey identified 25 botanic gardens in 14 countries undertaking 51 conservation projects focused on 27 Bern listed species. In particular this survey has established that the majority of taxa are held in a small number of collections, dominated by non-wild origin accessions, and are not adequately documented. The majority of specimens in botanic gardens are cultivated out of the range country and not contributing to a specific conservation project. We review the genetic representation and documentation of origin in collections. Existing plant collections contain representatives of populations, now lost in the wild and maintain samples of at least nine European plant taxa identified as 'Extinct in the Wild'. However, inadequate standards of record keeping has compromised the conservation value of many collections. We highlight the dangers of hybridisation and disease in ex situ collections. The results suggest that botanic garden collections are skewed towards horticulturally robust and ornamental species and do not fully reflect priorities as defined by the Bern Convention. Recognising the limitations of traditional botanic garden collections we propose that botanic gardens more effectively utilise their two core competencies, namely scientific horticulture and public display and interpretation. The unique horticultural skills resident in European botanic gardens could be more effectively utilised through the application of horticulture to the management of wild populations.
