Sustainability and Food: a Text Analysis of the Scientific Literature

The paper analyses the evolution of the research debate related to sustainability and to the relation between food and sustainability. A number of text analysis techniques were combined for the investigation of scientific papers. The results stress how discourse analysis of sustainability in the pre-Rio period is mostly associated with agriculture and with a vision where the ecological and environmental aspects are dominant. In the post-Rio phase, the discussion about sustainability, though still strongly linked to environmental issues, enters a holistic dimension that includes social elements. The themes of energy and the sustainability of urban areas become central, and the scientific debate stresses the importance of indicators within an assessment approach linked to the relevance of planning and intervention aspects. The focus on the role of food within the debate on sustainability highlights a food security oriented approach in the pre-Rio phase, with a particular attention towards agriculture and third world Countries. In the post-Rio period, the focus of the analysis moves towards developed Countries. Even though food security remains a strongly significant element of the debate, the attention shifts towards consumers and food choices

Gestione forestale sostenibile e servizi ecosistemici: un esempio di valutazione economico-finanziaria per i boschi toscani

The monetary evaluation of ecosystem services is a topic of great interest for environmental planning and forestry. However, economic measurements of forest externalities and the implementation of decision support tools able to guide decision-makers in forest assessment, are difficult tasks. In this framework, the aims of the work were: i) to define economic and financial indicators, related to appraisal of different silvicultural intervention in Tuscany forest and ii) to design a flexible economic decision support model for the guidance of stakeholders in forest management. From methodological viewpoint a short period financial analysis was developed. This analysis permits to compute stumpage value of forest harvesting. The innovative component of the work is the ability to integrate the analysis with an assessment of economic aspect of the process. As matter of fact, multifunctionality parameters and, consequently, total economic value of forest was introduced. Main results emphasize the flexibility of the implemented model and the potential application in different areas
