European Union funded projects must adhere to General Data Protection Regulations (GDPR) that govern the way in which personal data of stakeholders is gathered, stored, and used. In the H2020 project NEXOGENESIS, WEFE nexus interlinkages are assessed in five river basins, four in Europe and one in Southern Africa. This work is carried out in a participatory manner and stakeholder engagement plays a central role. Stakeholders were asked to actively consent to the collection, storage, and use of their information through a privacy policy consent form. Active engagement with stakeholders occurred in the first half of the project (2021-2023) through stakeholder workshops via different modalities in each of the five case studies, and targeted stakeholder interviews and focus group discussions. We show that the stakeholders that actively consent to the use of their information are not evenly distributed across all sectors but are generally from the water sector and have high interest and rather low power. Our study provides evidence that the need to sign a consent form reveals biases in the stakeholder landscape. Results also show that consent rates increased with active engagement situations and were relatively high through face-to-face interactions but were the highest in absolute terms through hybrid events. Using consent forms not only helps increase the transparency of how personal data of stakeholders is used, but also helps show the biases that are present in the active stakeholder base.
Integrated approach for the development of railway as a core dimension of spatial planning, 2024

This paper focuses on the application of an integrated approach supporting the development of railway in Greece. A Decision Support System (LIPSOR) was used in order key components, key actors and possible future states to be explored; alternative scenarios were designed and assessed in combination with policy goals and measures. The main outcomes indicated the need to upgrade rail infrastructure and services, increase railway extroversion and reinforce investments.

Complexity is the main characteristic describing this complicated system of interactions that affects the effective management of available resources at both physical and policy level. Thus, sectorial approaches have been proved rather insufficient and a holistic rationale is now suggested, placing emphasis on the systemic nature of the WEFE nexus. The achievement of SDGs and relevant sub-targets is also significantly affected by the sustainable use of resources as the core dimension of SDGs reflects the urgent need for the adoption of a more sustainable and resource-efficient pattern of development. This study elaborates on WEFE nexus indicators supporting sustainability in line with the priorities having been set by SDGs. Such indicators focus on issues strongly related to the several WEFE sectors such as flood alleviation, hydropower production, exploitation of biomass, rural/agricultural development, water quality protection, securing of environmental flow, food production and land use changes under climate change conditions. Moreover, the spatial dimension is taken into consideration as, according to the literature, the successful implementation and achievement of SDGs presupposes their specialization and adaptation to local needs and characteristics (e.g. country or regional level). Land use change in time (%), GHG emissions emanating from agriculture and livestock (%), crop yields (cereals, vegetables, etc.) (%), use of pesticides/fertilizers (kg) and water available for environmental flow (%) are among the proposed indicators. It should be mentioned that such indicators correspond to more than one SDG as emphasis was placed on covering as many aspects of SDGs as possible.

It builds upon the concepts of combating poverty & inequality, mitigating climate change impacts as well as protecting natural & cultural resources through innovation & adoption of eco-friendly solutions. It is a human-centric approach that places people at the core of its priorities. Seventeen Sustainable Development Goals (SDGs) have now been set by the United Nations (UN) for the year 2030, each accompanied by a set of indicators measuring their performance. This paper focuses on the contribution of each sustainability indicator to the accomplishment of the respective goals, especially in case of drylands. A general overview of the SDGs & the relative indicators are analyzed. Then, indicators related to climate change impacts are explored following by an assessment of the contribution of these specific indicators to the management of drylands under climate change conditions.

The specialisation of the 17 Sustainable Development Goals (SDGs) and indicators into local contexts constitutes a basic prerequisite as particular characteristics, needs and peculiarities should be considered. This paper focuses on the exploration of local-oriented indicators and policy recommendations that have the potential to boost the successful implementation of SDGs in Greece. A nexus approach is adopted underlining the need to analyse complexities, motivate systemic thinking and develop integrated policies targeting at the sustainable and efficient use of resources. It also highlights the need for designing local-specific indicators and policy initiatives, encapsulating particular characteristics and conditions and boosting the advancement...

Il presente studio mira a sviluppare un quadro metodologico che possa accogliere strumenti partecipativi durante la fase di valutazione nell'ambito del processo di pianificazione. Un simile quadro può supportare i planner e i decision maker nel: valutare scenari alternativi, includere molteplici prospettive e considerare possibili "alleanze" o "conflitti" tra diversi gruppi di interesse, migliorando così le opzioni strategiche. Tale approccio è applicato a una particolare regione greca in cui sono stati valutati scenari alternativi per i...

The focus of the present paper is on the development of a methodological framework that can accommodate participatory tools at the stage of the evaluation in the planning process. Such a framework can support planners and decision makers to: evaluate alternative scenarios, incorporating multiple perspectives; and explore potential 'alliances' or 'conflicts' among different interest groups, thus improving policy options. This approach is applied to a specific Greek region, where alternative scenarios for its future development were evaluated, following a participatory planning context.

Η θεώρηση υπό την οποία αντιμετωπίζεται το ζήτημα αυτό, είναι η διαχρονική μεταβολή του μέσα από τη δράση ενδογενών και εξωγενών παραγόντων που δύνανται να επιδράσουν στην εξέλιξή του και να το αναδιαμορφώσουν. Συνεπώς, ο ελληνικός σιδηρόδρομος αντιμετωπίζεται ως ένα ανοικτό σύστημα, που υφίσταται τις επιδράσεις του εξωτερικού περιβάλλοντος και κατά περίπτωση ασκεί και ο ίδιος επίδραση σε αυτό. Διαμορφώνεται λοιπόν μια σχέση αλληλεπίδρασης ανάμεσα στο εσωτερικό και το εξωτερικό περιβάλλον του σιδηροδρομικού συστήματος. Οι προοπτικές ανάπτυξης του ελληνικού σιδηροδρομικού δικτύου είναι μεγάλες και ο σιδηρόδρομος έχει τη δυνατότητα να καταστεί ένα ανταγωνιστικό μέσο που θα κερδίσει τις προτιμήσεις του επιβατικού κοινού και των παραγόντων του εμπορίου. Ιδιαίτερη έμφαση θα πρέπει να δοθεί στην ανάπτυξη της σιδηροδρομικής υποδομής στο σύνολό της, στις διεθνείς διασυνδέσεις του σιδηροδρομικού δικτύου της χώρας με τα...

Ουσιαστικά, πρόκειται για την υλοποίηση μιας client-server εφαρμογής (εφαρμογής πελάτη- εξυπηρετητή), η οποία παρέχει στο χρήστη τη δυνατότητα εύρεσης της συντομότερης διαδρομής μεταξύ του σημείου στο οποίο βρίσκεται και του σημείου στο οποίο επιθυμεί να μεταβεί. Το πρόβλημα εύρεσης συντομότερης διαδρομής αφορά κατά κύριο λόγο το σχεδιασμό δικτύων ή την επίλυση προβλημάτων που σχετίζονται με ήδη υπάρχοντα δίκτυα. Το ζητούμενο είναι συνήθως η εύρεση της βέλτιστης διαδρομής, μέσω της οποίας καθίσταται δυνατή η μετάβαση από ένα σημείο του δικτύου σε κάποιο άλλο τηρουμένων κάποιων κριτηρίων τα οποία σχετίζονται με την απόσταση μεταξύ των σημείων αφετηρίας και προορισμού, με το χρόνο διάνυσης της συγκεκριμένης διαδρομής, την ελαχιστοποίηση του κόστους των διοδίων κ.λπ. Η ραγδαία ανάπτυξη εφαρμογών πλοήγησης σε δίκτυα απαιτεί την αποτελεσματική επίλυ...

During the last few years, crowdsourcing has become popular among companies, institutions and universities, as a crowd-centered modern "tool" for problem solving. Crowdsourcing is mainly based on the idea of an open-call publication of a problem, requesting the response of the crowd for reaching the most appropriate solution. The focus of this paper is on the role of crowdsourcing in knowledge acquisition for planning applications. The first part provides an introduction to the origins of crowdsourcing in knowledge generation. The second part elaborates on the concept of crowdsourcing, while some indicative platforms supporting the development of crowdsourcing applications are also described. The third part focuses on the integration of crowdsourcing with certain web technologies and GIS (Geographic Information Systems), for spatial planning applications, while in the fourth part, a general framework of the rationale behind crowdsourcing applications is presented. Finally, the fifth part focuses on a range of case studies that adopted several crowdsourcing techniques.

Economic growth, social cohesion, and environmental protection are straightforwardly linked to the “smart” dimension of cities, implying the use of technology in almost all urban functions. Such a pattern of urban development stimulates the accomplishment of Sustainable Development Goals; especially the one concerning the promotion of safe, resilient, inclusive, and sustainable cities (SDG 11). Specific targets clarify this general perspective, highlighting issues like standards of living, transportation services, climate change adaptation, etc. Each target is accompanied by an indicator measuring its performance. This chapter focuses on the role of smart technologies in achieving SDG 11. The key fundamental axes of smart cities are explored. Thereinafter, the focus shifts on the investigation of technologies supporting/upgrading city functions while their contribution to the accomplishment of SDG 11 is examined.

The present paper focuses on policy analysis process and its pivotal role in decision making for the efficient management of the available natural resources. In this context, we identify, analyze and assess several policies concerning the nexus water-energy-food-land-climate and the existing interrelations among these components. Policies regulating the agricultural and tourist sectors are also analyzed. A compact methodological framework guides policy analysis process on the basis of which, we investigate individual policy areas, goals, means and potential interactions among policies. The key research questions concern: a) the harmonization of the national and European legislation, b) the exploration of goals and targets of policies dealing with water, energy, land, food, climate and c) the exploration of means supporting the implementation of the aforementioned goals.

The nodes of the drainage system that are most vulnerable to flood are determined based on eight indices: (i) conveyance (calculated using Manning equation for conduits) (m3/s); (ii) subcatchment area (m2); (iii) subcatchment width (m); (iv) subcatchment average slope (%); (v) manning coefficient of the impervious part of the subcatchment (s/m1/3); (vi) Manning coefficient of the pervious part of the subcatchment (s/m1/3); (vii) impervious area of the subcatchment (%); and (viii) SCS runoff Curve Number.
Four manholes (alternatives) are evaluated with respect to the aforementioned indices (evaluation criteria) as to their vulnerability to flood. The manholes are ranked from the most “risky” to the less “risky”. To this end, two different MCDA methods are applied, the Weighted Summation method and the Electre II method, while criteria weights are estimated by using the Analytic Hierarchy Process (AHP) and the respective Saaty scale (Saaty, 1977). Both Weighted Summation and Electre II are discrete quantitative methods dealing with quantitative data on the basis of alternative consequences and priorities (weights) assigned to the evaluation criteria (Janssen, 1992).
The WEFE nexus approach is adopted in order to: a) support the attainment of social, environmental and economic objectives, in line with SDG priorities, b) develop more efficient and sustainable patterns of resource use, and c) improve modeling and management of trade-offs among the several nexus sectors. As a result, academicians, decision-makers, NGOs and the business sector must be able to identify mutually beneficial actions to maintain the sustainability of ecosystems, via the understanding of the interactions between the WEFE sectors. The aim of the present work is to introduce an integrated evaluation system for assessing the sustainability of the WEFE nexus in river basins. The proposed approach is based on the exploitation of the feedback gained during two separate Stakeholder (SH) Workshops, the Drivers–Pressures–States–Impacts–Responses (DPSIR) framework, and the Analytic Hierarchy Process (AHP) method.
