Responsibility in uncertain times: an institutional perspective on precaution
2008
Precaution is a key issue in environmental governance. Variously defined, intensively debated and introduced in many regulations, its meaning, scope and application remain problematic. This article argues that the controversy on precaution is a matter of culturally patterned expectations concerning the production and use of knowledge and the related social positions and responsibilities. The way uncertainty and its role in the policy process are understood is crucial. For some precaution is a flawed concept, to be accommodated to the current expert-based cooperative scheme. For others it is a major innovation requiring a rearrangement of the latter. Precautionary policies may evolve in dif…
The chariots of Pharaoh at the Red Sea The crises of capitalism and of environment. A modest proposal towards sustainability
2016
The present global situation recalls us the two walls in which the Red Sea had split to allow that Pharaoh follow the people beloved by God. On one wall stays the economic crisis, that is tout court the capitalist crisis, on the other wall there is the predicament of environment. Then, it is reasonable to wonder if the walls will tumble down with severe damages to all the characters, this time, of this representation; unless a “modest proposal”, of the kind that we will try to formulate in this paper, be intensively pursued. Several of the themes here gathered have already been object of reflection in some previous works. In this paper we collect and enrich those ideas, and put a special at…
Prefazione
2014
Le politiche sull’ambiente assumono un ruolo fondamentale e sempre più importante, perché possono riuscire a modificare quei comportamenti che, se accompagnati a politiche economiche di sostenibilità, possono permetterci di raggiungere un equilibrio tra la salvaguardia delle risorse naturali esistenti, e un loro corretto utilizzo, in modo da proteggerne l’integrità. Il volume contiene i contributi presentati in occasione del convegno organizzato dall’AIL e dall’Università degli studi di Palermo su “Cancerogenesi Ambientale” (Palermo 2013).

L'albero e l'anello. Natura e geografia nel Signore degli Anelli
2011
L'obiettivo del testo è mostrare come alcune opere fantasy contemporanee, a partire dal capostipite tolkieniano, non si limitino a raccontare storie di maghi, mostri e battaglie, ma interpretino il sentire ecologista della nostra epoca, trasformandolo in chiave mitica. Il mondo del fantasy non è un riflesso apocalittico e distorto della modernità proiettata nel futuro, ma sembra più il rimpianto per un passato aureo e irraggiungibile, in cui la vita era più semplice e meno incerta.
Biological Nutrient Removal Model No. 2 (BNRM2): a general model for wastewater treatment plants
2013
This paper presents the plant-wide model Biological Nutrient Removal Model No. 2 (BNRM2). Since nitrite was not considered in the BNRM1, and this previous model also failed to accurately simulate the anaerobic digestion because precipitation processes were not considered, an extension of BNRM1 has been developed. This extension comprises all the components and processes required to simulate nitrogen removal via nitrite and the formation of the solids most likely to precipitate in anaerobic digesters. The solids considered in BNRM2 are: struvite, amorphous calcium phosphate, hidroxyapatite, newberite, vivianite, strengite, variscite, and calcium carbonate. With regard to nitrogen removal via…
Siose Valencia 2005: resultados, aplicaciones y comparación con Corine
2011
SIOSE, Spanish acronym standing for Land Cover and Use Information System of Spain, is the most detailed Geographic Information System ever created in Spain about land cover and land use. This GIS gives objective information, photo-interpreted from aerial and satellite imagery, describing the different land covers and land uses. Since SIOSE gathers a big deal of information (more than 157.000 different polygons just in the Land of Valencia), the quantity of possible researches coming from it is huge and ranging from environmental and biodiversity subjects to agricultural or urban areas topics. These possible researches would be especially appropriate on a local level, since SIOSE has a very…
