Abstract Treated wastewater is expected to constitute an essential part of the urban water cycle as an additional water resource in water-scarce or densely populated regions in the future. As decisions on the implementation of water recycling measures should always consider local conditions, the project ‘MULTI-ReUse: Modular treatment and monitoring for wastewater reuse’ has developed a comprehensive sustainability assessment tool, designed to support decision-makers in examining the technical feasibility, economic viability, ecological compatibility and social acceptance of alternative service water supply solutions at local level. This article describes the structure of this sustainability assessment tool and its underlying multi-criteria assessment approach based on 23 evaluation criteria. Already in the development phase, the tool was tested in a German and a Namibian case study. Both case studies are presented with a special focus on the technologies used and the results of the analysis with the sustainability assessment tool. Case study testing proved that the tool is applicable in various environmental and societal settings with widely differing climatic conditions, limited resource availability, for varying feed water qualities and water quality requirements. The comprehensive, straightforward assessment approach enabled the local users to identify the most sustainable supply system or strategy for their decision case.

Dependence of conventional agricultural systems on chemical fertilizers and pesticidesmakes agricultural systems less stable and important drift polluters influencing to theregional and global sustainability. This problem made human being think about thealternative systems: agricultural systems that mimic natural systems and are friendly to theenvironment; those have higher economical efficiency concerning production level andcosts. The objective of the present study was sustainability assessment and comparison oforganic and conventional system with special focus environmental and economicalperformance. The case study consisted of two organic and conventional olive producingfarms in the South of Italy. The method used for sustainability assessment wasEnvironmental Accounting Information System (EAIS) that integrates togetherenvironmental (soil organic matter, soil erosion, genetic and landscape biodiversity,EPRIP, etc ) and economical indicators (gross margin). Data used for assessment ofEAIS indicators values were mainly collected from: farm economic-accounting systems,interviews, farm maps, area public organizations, bibliographical sources, farm nutrientaccounting systems, observations and field assessments and chemical soil analyses. Theindicator values measured into two farms were compared to theoretical or referenceindicator values. Based on indicator assessment it was concluded that organic olivegrowing farm had better performance than conventional farm.

Treat Acid Mine Drainage

Several technologies have been developed to treat acid mine drainage (AMD) and attention is shifting towards the removal of sulphate. The formation of ettringite, a hydrous calcium aluminium sulphate mineral, is an option to treat AMD and can reduce the sulphate concentration to well below the discharge specifications. The process modelled in this study includes the formation of ettringite and the recovery of gibbsite through the decomposition of recycled ettringite. The modelling of this process was done using PHREEQC and the results presented in this paper are based on the outcome of different case studies that investigated how the process is affected by a change in parameters. These include, changing the feed water pH, altering the split fractions in the hydrocyclone for the gibbsite recovery and varying the pH for ettringite formation.

Security Risk Assessment

Risk-driven testing and test-driven risk assessment are two strongly related approaches, though the latter is less explored. This chapter presents an evaluation of a test-driven security risk assessment approach to assess how useful testing is for validating and correcting security risk models. Based on the guidelines for case study research, two industrial case studies were analyzed: a multilingual financial web application and a mobile financial application. In both case studies, the testing yielded new information, which was not found in the risk assessment phase. In the first case study, new vulnerabilities were found that resulted in an update of the likelihood values of threat scenarios and risks in the risk model. New vulnerabilities were also identified and added to the risk model in the second case study. These updates led to more accurate risk models, which indicate that the testing was indeed useful for validating and correcting the risk models.

Insight Into

This research provides an assessment tool that assists the selection process of sustainability in detached suburban housing. It investigates the implications of using different design and construction methods including architecturally designed houses, developer housing and prefabricated houses. The study simulates one example of the three types of houses that have been chosen to fulfil a real client brief on a real site on the Sunshine Coast, Queensland Australia. Criteria for sustainability assessment are formulated based on literature reviews, exemplar designs and similar research projects for which the houses can be adequately evaluated. This criterion covers aspects including energy use, materials and thermal performance. The data is collected using computer models and sustainability assessment software to compare and draw conclusions on the success of each house.Our study indicates that architecturally designed housing with prefabricated building techniques are a better alternative to generic developer style housing. Our research provides an insight into the implications of three key elements of sustainability including energy use, materials and thermal performance. Designers, builders, developers and home-buyers are given an insight into some options currently available on the housing market and how the choices made during early design stages can provide a more positive environmental impact.

TESS partners were asked to develop local level case studies for Estonia, Germany, Greece, Hungary, Poland, Portugal, Romania, Turkey, and the UK. All studies consisted of a socioeconomic project and a mapping project, except that there was mapping alone in Germany. The aims of the case study projects were to test how best to meet local decision support needs in exchange for local monitoring that meets central policy requirements and whether local monitoring (based on schools, local community groups, or individuals motivated by use of wild resources) can meet government requirements. Such information requires mapping of ecological information, for combination with socio-economic information; the case studies also aimed at assessing local attitudes and capabilities. This chapter presents an overview of results from the studies, which are described individually in the following nine chapters.

Across Europe, landscape is recognised as a frame through which societal values are defined and embedded. The European Landscape convention and wider research has drawn attention to the need for integrating a diverse range of stakeholders to ensure landscape sustainability. Archaeology is increasingly recognised as having an important place in integrated landscape management but often remains relatively peripheral. This paper examines the place of archaeology in specific European regions and the potential ways of integrating archaeological heritage in landscape management. Emerging from a project funded by the Joint Programme Initiative on Cultural Heritage (Resituating Europe’s FIrst Towns (REFIT): A case study in enhancing knowledge transfer and developing sustainable management of cultural landscapes), we explore the place of a set of common European heritage assets, Iron Age oppida, in the management of the landscape they are a part of and how they might be used better to engage and connect stakeholders. Using four case studies, we review the present integration of archaeology within landscape management and how this operates at a local level. From this we explore what challenges these case-studies present and outline ways in which the REFIT project has sought to develop strategies to respond to these in order to enhance and promote co-productive management of these landscapes.

The Impact

This study aims to understand how the health dimension is integrated into four impact assessment tools used in Geneva, Switzerland: environmental impact assessment (EIA), strategic environmental assessment (SEA), sustainability assessment (SA) and health impact assessment (HIA). We have chosen as a case study greenhouse gas (GHG) emissions reduction policies chosen by the city of Geneva. The methodological approach consists in analysing EIA, SEA, SA and HIA conducted on three projects in three topic areas: urban planning, heating and transportation. These projects are: a complex urbanisation plan in an urban neighbourhood in Geneva (the Gare des Eaux-Vives project), a sustainable transportation plan for a central district in Geneva (the St-Gervais transportation project) and a strategy to encourage the City’s employees to use sustainable transport for local business travel. The results show some shortcomings in the consideration of health in SEA, EIA and SA. This work highlights a narrow vision of health in SEA and EIA, limiting itself to a review of the effects of projects on the determinants of the physical environment as required by the legislation relating to these tools. EIA does not require the integration of the health dimension. As for SA, our research found that health is treated much more superficially than in HIA and primarily through the analysis of ‘health and safety’ criteria. It appears from this work that HIA is the tool which provides the most elaborate assessment, compared to SA, SEA or EIA, of the consequences for health of the GHG reduction policies chosen by the local decision-makers of a city. However, our study suggests that the HIA community should identify the situations in which HIA should be carried out and in which cases it is better to include health issues within an integrated analysis.

Modeling interaction with robots raises new and different challenges for dialog modeling than traditional dialog modeling with less embodied machines. We present four case studies of implementing a typical human-robot interaction scenario with different state-of-the-art dialog frameworks in order to identify challenges and pitfalls specific to HRI and potential solutions. The results are discussed with a special focus on the interplay between dialog and task modeling on robots.

Cultural And Creative Industries

This article examined the level of integration of the concept of Cultural and Creative Industries in strategic documents decisive for public policy implementation. On the case study of the Czech Republic, concrete goals, tools and measures of respective policies were examined, special focus has been laid on the implementation power and coordination mechanisms. In the methodological framework of the Multi-level Governance Concept, methods of content and comparative analysis were used. As the analysis shows, on the central level is the concept of CCIs explicitly reflected and very well elaborated, with concrete goals and instruments to achieve the given goals, on the local level predominantly the „cultural part“ is stressed, having the „creative aspects“ hidden in other policy areas. Concerning the local level, there is a „two axes“ flow. On one side, examined policy paper stresses the importance of culture for own citizens, especially for the community and identity feeling, promotion of a good name of the city (region, municipality) and last, not least, the identification of citizens with the place they live in. On the other hand, the second line aims at attracting tourists through a complex combination of cultural heritage visits, connected with various experience events.
