MADFORWATER. WP5 Strategies and economic instruments for basin-scale water resources management. Treated Wastewater reuse on Citrus in Morocco. Assessing the Economic Feasibility of irrigation and nutrient management strategies
No full textReuse of treated wastewater (TWW) for irrigation can be an effective strategy in Mediterranean countries to overcome the pressure on freshwater resources if its economic viability is demonstrated. In this work, the assessment of the economic feasibility of irrigation and nutrient management with TWW reuse was carried out in the citrus sector in the Souss Massa region, in Morocco. Considering the effects of TWW reuse on yields, water and fertilizer requirements, a mathematical non-linear optimization model was used to identify the optimal allocation of land and of non-uniform quality irrigation water and to assess the impacts on the economic performance of the citrus sector. Different water price and irrigation technology scenarios have been simulated. Overall results indicated that the re-use of TWW - with a current price higher than the conventional resource - must be subsidized to be proposed as a convenient alternative for irrigation. A reduction in the TWW price from its current level (0.23 Euro / m3) to a level equal to that of fresh water (0.15 Euro / m3) would encourage farmers to use TWW on 59% of the total cultivated area, leading to a 350 mm reduction in quantity of used fresh water per hectare
Covid-19 Impact on Platform Economy. A Preliminary Outlook
Get PDFWith this report, PLUS consortium wants to contribute to a large debate on the role of platform economy and on how to deal with labour transformations after Covid-19 outbreak. Considering the ongoing very unpredictable situation, the observations contained in the report should be considered as explorative to further investigations. In any case, we would suggest to avoid framing Covid-19 outbreak in 2020 as outstanding event clearly dividing what occurred before from what will occur shortly after. Rather, one of the purposes of this report is to test if some of the hypothesis we produced during the first year and half of the project are still persuasive even after virus appearance. At first sight it seems that Covid-19 pandemic highlights and, if anything, emphasizes very well some platforms characteristics we had already identified: the lack of social protections for platform workers, the becoming essential infrastructures of platforms, the digitalization of services, the changing nature of urban economies

Get PDFThis document represents deliverable D2.4 “Report on WP2 lessons learned” within work package WP2 “Diagnostic of existing experiences on AECPGs” of the EU Horizon 2020 project CONSOLE. The document brings together results and conclusions of WP2 Task 2.5. Particularly, the results from the analysis of solutions from inside the EU will be complemented with experiences beyond the CONSOLE EU case studies in order to derive inspiration and additional ideas for improvements of European solutions in WP3 and WP4. Moreover, the lessons learned will give first an overview for policy makers on innovative and successful solutions “outside the box”
Posted work: informality and social regulation
Get PDFPosting represents a growing dimension of intra-European mobility. This ebook proposes an analysis of posted work, based on transnational research conducted with Portuguese workers in the construction sector in France. Inspired by Reynaud’s theory of social regulation, the approach adopted considers posted work as a social system, opposed to traditional industrial relations. The result of the regulation process shows a shift from migration to mobility characterized by poor working conditions and unofficial negotiations and agreements. But posting cannot be considered as “informal” employment. Posting creates its own rules that need to be considered as much as legal elements in order to understand the growing trend and the use of these workers
Treated Wastewater Reuse on Citrus in Morocco: Assessing the Economic Feasibility of Irrigation and Nutrient Management Strategies
Get PDFReuse of treated wastewater (TWW) for irrigation can be an effective strategy in Mediterranean countries to overcome the
pressure on freshwater resources if its economic viability is demonstrated. In this work, the assessment of the economic
feasibility of irrigation and nutrient management with TWW reuse was carried out in the citrus sector in the Souss Massa
region of Morocco. Considering the effects of TWW reuse on yields, water, and fertilizer requirements, a mathematical
nonlinear optimization model was used to identify the optimal allocation of land and nonuniform quality irrigation water and
to assess the impacts on the economic performance of the citrus sector. Different water price and irrigation technology
scenarios have been simulated. Overall results indicated that the reuse of TWW—with a current price higher than the
conventional resource—must be subsidized to be proposed as a convenient alternative for irrigation. A reduction in the
TWW price from its current level (0.23 Euro/m3
) to a level equal to that of fresh water (0.15 Euro/m3
) would encourage farmers
to use TWW on 59% of the total cultivated area, leading to a 350 mm reduction in quantity of used fresh water per hectar
Argomenti per considerare le navi di Nemi come giganteschi organi musicali idraulici dell’imperatore romano Caligola
Get PDFDopo una breve premessa sul funzionamento degli organi musicali idraulici e un cenno della loro diffusione nella Grecia antica e nell’impero romano, superando il mistero sommerso nel lago (My), si pone l’ipotesi che le cosiddette navi romane di Nemi potessero essere giganteschi organi musicali suonati dall’imperatore o per l’imperatore nello specchio di Diana e se ne argomentano i motivi.
Una rilettura nei Commentarii di Enea Silvio Piccolomini sul viaggio apud Albanum dissolve ogni possibile dubbio sulla interpretazione che le navi fossero organi musicali e porta un notevole contributo per individuare il tipo di hydriam fictilem e cioè un organo con canne in tubi di terracotta, ritrovati peraltro in gran numero. Si chiude auspicando che gli studi su queste macchine possano proseguire sul materiale tuttora disponibile e che si possano in qualche modo riascoltare le armonie di allora in un luogo così pieno di storia e di magia
Water vulnerability assessment framework
Get PDFThe present deliverable report is related to Task 1.4 of the MADFORWATER project. The aim of the current report is double: (1) To define a framework for the development and assessment of integrated water & land management strategies (IWLMS) at basin level. This will be subsequently implemented in WP5 and WP6 of the MADFORWATER project. (2) To assess water security on a scale lower than the national level (as it was done in Task 1.2 of the MADFORWATER project) in order to provide a better understanding of the current water management practices and water vulnerabilities of the MADFORWATER selected basins: Souss-Massa basin in Morocco, Cap-Bon and Miliane basin in Tunisia, and the North-Eastern Nile Delta sub-basin in Egypt.
It became apparent, during the execution of the MADFORWATER project, the need to handle a stronger consistency of indicators and information across different scales. In this view, Deliverable 1.4 focused on a systematic analysis to understand how the impact of potential local measures in the field of wastewater reuse could be assessed at different scales. Results were then used to derivate the assessment framework accordingly
Atti del XXII Convegno Nazionale di Agrometeorologia Ricerca ed innovazione per la gestione del rischio meteo - climatico in agricoltura
Get PDFIl rischio è una componente intrinseca all’attività di impresa. Nessun imprenditore, nel momento in cui assume una decisione, è sicuro delle conseguenze che essa avrà sui risultati economici. Ed è proprio il rischio connesso agli esiti delle decisioni che è all’origine del profitto. Nel caso dell’agricoltura, il carattere biologico dell’attività aggiunge un ulteriore elemento di rischio alle decisioni degli imprenditori del settore. In particolare, l’andamento meteorologico durante la stagione colturale ha un ruolo preponderante, e il rischio meteorologico viene definito come la capacità delle aziende di gestire entrate, costi e performance finanziarie sensibili alle condizioni meteorologiche.
L’incertezza meteorologica è sempre esistita, ma nel nuovo clima alcuni fenomeni negativi per l’agricoltura hanno aumentato la loro frequenza, mentre altri fenomeni si sono aggiunti alla lista:
temperature massima e minima oltre soglie di criticità termica, pioggia massima giornaliera oltre soglie di criticità, vento con intensità al di sopra di soglie di criticità, grandine, fulmini e tempeste elettriche, alluvioni. Inoltre si verificano con più elevata frequenza sfasamenti stagionali, precipitazioni brevi ed intense e si ha un maggiore rischio di gelate tardive. Uno o un insieme di questi fenomeni concorrono, uniti alla frequenza di accadimento, a definire la possibilità di successo dell’agricoltore.
In questo contesto l’AIAM propone, per il 22° convegno Nazionale, temi riguardanti lo studio del cambiamento climatico e dei rischi per l’agricoltura, quali sono gli strumenti per la previsione e le strategie per la prevenzione del rischio, e come i servizi agrometeorologici supportano gli agricoltori nella difesa integrata delle colture agrarie
A report with techniques for evaluation of CRMs variability
Get PDFTask 3.2 of WP3 consisted of reviewing characterization techniques for understanding presence of raw materials (with special reference to critical raw materials - CRMs) inside the mining wastes (both stockpiles and tailings). The review covers different aspects, such as EU legislation in mining wastes management, environmental characterization of historical mining areas for pollution detection, grade characterization for recovery of valuable metals, innovative ways and approaches to understand the presence and value of CRMs within the entire mine life cycle. The present Deliverable 3.2 concludes with comments on the current standards and suggestions about a more effective characterization for practical and economic recovery of CRMs from stockpiles and tailings
