Mapping the Lisbon potential foodshed in Ribatejo e Oeste: a suitability and yeld model for assessing the potential for localized food production

ArticleResearch on food planning has been recently proposed in North American and European planning to account for how cities might change their food provision to respond to the rising demands for a more sustainable and ethical food system. The purpose of this paper was to evaluate the agro-ecological potential of the Lisbon city region, Ribatejo e Oeste, to increase its Regional Food Self-Reliance (RFSR), through adopting demand restraint and food system relocalization approaches to food system sustainability. Three new diet scenarios were considered: meat-based, plant-based and strict vegetarian, defined in accordance with healthy dietary patterns. We used agro-climatic and agro-edaphic agricultural suitability models to evaluate the agro-ecological potential for RFSR, and proposed the use of Foodshed Landscape Plans within a landscape planning methodology. Results showed the extent of local food production that could improve food self-reliance, with 72%, 76%, 84% of total food needs in the meat-based, plant-based, and strict vegetarian scenarios, respectively. Thus, food system transformation by means of relocalization, is therefore ecologically feasible and would ensure the sustainable use of the ecological basis of food security. Additionally, a dietary transition would imply significant land sparing, which strengthens the demand restraint perspective for a transition to food system sustainabilityinfo:eu-repo/semantics/publishedVersio

Ordem ecológica e desenvolvimento. O futuro do território português

O estudo realizado permitiu tirar algumas conclusões relativamente à ocupação do solo, em Portugal, reportandose a 2007, data da última carta de ocupação e uso do solo (COS). Estas conclusões pressupõem a base ecológica do território, avaliada através da aptidão ecológica aos grandes grupos de actividades humanas, incluindo agricultura, silvicultura e edificação, às culturas agrícolas, às espécies arbóreas, pastagens espontâneas e aos matos. As metodologias utilizadas são descritas ao longo deste livro. Seguidamente apresentam-se as conclusões consideradas mais importantesinfo:eu-repo/semantics/publishedVersio

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
