An original methodology for the Water Footprint Assessment (WFA) of a Product for the wine-making industry sector is presented, with a particular focus on the evaluation procedure of the grey water. Results obtained with the proposed methodology are also presented for an Italian case study. The product was analyzed using a life-cycle approach, with the aim of studying the water volumes of each phase according to the newly-released ISO 14046 international standard. The functional unit chosen in this study is the common 0.75 liter wine bottle. An in-house software (V.I.V.A.) was implemented with the goal of accounting for all the contributions in a cradle-to-grave approach. At this stage, however, minor water volumes associated with some foreground and background processes are not assessed. The evaluation procedure was applied to a case study and green, blue, and grey water volumes were computed. Primary data were collected for a red wine produced by an Umbrian wine-making company. Results are in accordance with global average water footprint values from literature, showing a total WF of 632.2 L/bottle, with the major contribution (98.3%) given by green water, and minor contributions (1.2% and 0.5%) given by grey and blue water, respectively. A particular effort was dedicated to the definition of an improved methodology for the assessment of the virtual water volume required to dilute the load of pollutants on the environment below some reference level (Grey WF). The improved methodology was elaborated to assure the completeness of the water footprint assessment and to overcome some limitations of the reference approach. As a result, the overall WF can increase up to 3% in the most conservative hypotheses.

In this paper we analyse the role played by cross-border organisations in the Guadiana river basin in Iberia, and the extent to which new emerging institutional arrangements carry on adaptive management practice as a response to mounting climate change risks in the river basin. Particular attention is paid to the new transboundary agencies, as promoted by the EU INTERREG programmes, and their potential for mainstreaming climate change considerations into Guadiana river basin development strategies. Results indicate that the penetration of climate change concerns into regional development policies requires a better integration of different policies and improved connectivity and coordination between multiple actors operating across sectors, and at different spatial scales. We argue that the emergence of new transboundary agencies capable of performing these bridging functions is a vital ingredient for building climate adaptive capacity in these cross-border regions.

The European Union’s Farm-to-Fork strategy, aiming at increasing the environmental sustainability of farming, is oriented to limit farm inputs that could harm the environment. This restrictive policy affects farmers’ productive choices and economic well-being. However, limited attention has been paid to how this could affect the economic risk farmers face. To do so, we examine how risk is affected by fertilisers, crop protection, irrigation water, and labour choices. This study relied on Antle’s method of moments applied to the irrigated field crop farms of the Italian Farm Accountancy Data Network from 2008 to 2019. This paper fills the literature gap jointly using three aspects usually adopted separately. First, consider the three moments and the semi-variance to investigate the risks of farmers’ strategies. Second, it accounts also for government payments to consider the relationship between these and risk. Finally, it adopts an estimation strategy that relies on the Generalised Method of Moments (GMM) for the first step and the Fixed Effects-Generalized Least Squared (FE-GLS) estimator for the second, considering time and individual fixed effects and considering interaction terms effects. According to our research, constraining fertilisers, crop protection, and irrigation water increases income variability, causing farming to be potentially riskier. However, restricting fertilisers and crop protection use decreases the downside risk. These results indicate that policy measures constraining input use, such as those foreseen in the EU, strongly influence the extent and type of risks farmers face. Therefore, policymakers should consider this evidence when designing environmental policies.

In numerous locations of bulk water supply/distribution systems, energy is dissipated by pressure-reducing devices, whereas it could be recovered by means of turbines or pumps as turbines. These pipe systems, owned and operated by municipalities, water utilities, large water-consuming industries, and mines, could be used as a source of renewable sustainable energy. However, the exploitation of these systems presents several issues related to the complexity of the operational optimization of the hydropower generation facilities and to the potential negative impact on the reliability of the system itself. We have developed a novel procedure to optimize the energy generation in such a conduit system by assessing the interrelationship of storage volumes, demand patterns, operating cycles, and electricity tariff structures. The procedure is a multi-objective genetic algorithm designed to provide a solution to maximize electricity generation and thus revenue and to minimize the risk involved in supplying the demand. A Pareto-optimal trade-off curve is set up, indicating the potential benefit (revenue) versus the reliability index (supply security). The results indicate that a Pareto-optimal trade-off curve was generated from which a solution could be selected which would improve the weekly revenue by up to 7.5%, while still providing a reliable water supply system.

This paper describes Che wave studies, model testing and structural design of a 250 metre long slotted vertical screen breakwater for a marina at Plymouth, England. The marina is being developed by Plymouth City Council to provide a purpose built facility for hosting the major long distance races that start or finish at Plymouth, in addition to the usual marina facilities for private boat owners. After examining three alternative locations Plymouth Council selected a site in the north-east corner of Plymouth Sound as shown in Figure 1. The site is confined on two sides by existing shipping channels and by a rocky shore on the land side. Exposure to wave attack is limited to the south west sector. Because the existing seabed at the marine site was the responsibility of the Duchy of Cornwall, an Act of Parliament was required before Plymouth Council could commence construction. The Act contains clauses regulating the use of the marina and the permissable changes to the wave conditions in the adjacent shipping channels.
