The memory of water. Hydrosocial fragility and urbanisation in Cagliari. – In Italy, the modern abstraction of human beings from the environment has led to a strict technicist management of natural resources and to a clear separation between urban and social policies, not entirely overcome by the National Recovery and Resilience Plan (PNRR). In particular, urban strategies struggle to reason about the role of water in the territorial system, relegating it to technical risk management interventions. From the debate around the mesological approach, various declinations of the relationship between human presence and water outline an often-chaotic palimpsest of plans and visions of urban space.
The contribution addresses the case study of the Cagliari municipality of Pirri, in the relationship between the historical condition of hydrogeological and social fragility and the new urban strategies to contrast risk. This systemisation is possible by adopting a reading of Pirri as a hydro-social territory, which allows us to critically reconstruct the history of the hydro-social fragility of this territory and consequently to re-read past and future planning policies.

The management of water resources in mountain contexts in ecological transition. – The frequency and concatenation of environmental and climatic phenomena requires a reflection on our way of managing the change, and in this direction the principle of “custody of the high lands” enhances the awareness of the communities on ecosystem services related to the precious water resources, essential to the biodiversity and the basis of stable economies for the mountain. The contribution intends to build a critical framework on interventions oriented to stem the water crises, adopted in the most vulnerable national mountain areas but which at-tempt the difficult territorial transition path on the climate tendency scenarios. The strategies will be analyzed, promoted by regional legislation and innovative regulations, for the territorialization of the actions on the management of the resource, but also complex projects and multi-sectoral studies with direct repercussions on physical and cultural landscapes, which therefore lead to inclusive forms of governance and participate.

Glaciers and Water bodies: Considerations and Emerging Prospects in Alpine Settings. – This research highlights the importance of the relationship between glacier health, snow cover, water resources availability and territories in the Alpine region. Snow has the strategic task of protecting glaciers, feeding freshwater reserves, regulating sea level and supporting local communities. However, snowfall is decreasing and snow and ice are melting faster due to global warming. Therefore, planning future risk management strategies is mandatory for water governance and environmental protection. In this regard Engadin represents an interesting case study. In this region, a local project aims at slowing down the retreat of the Morteratsch glacier. Moreover, a watercourse renaturation project has also been implemented in order to overcome the problem of substantially increased river flow due to rapidly melting glaciers. These are examples of policies that should take into account current climate changes and the physical conditions of the mountain environment.

Analysis and perspectives on water stress reduction: territorial implications and innovative approaches. – Ensuring water sustainability through technological innovation is crucial, especially for groundwater, a vital component linked to the hydrological cycle. It plays a pivotal role in supplying drinking water for various purposes, including agriculture and industry. Climate change pose significant threats to groundwater conservation, raising concerns about both quantity and quality with significant socio-economic implications. Effective preservation requires hydrogeological monitoring of underground basins, coupled with dynamic water balance modelling to provide predictive insights. These modern tools are essential for proper physical resource management. Implementing innovative technologies and strategic political and management planning for underground aquifers are imperative for initiating a robust program to mitigate risks and achieve a sustainable balance for this precious resource.

The river in the city: requalification and shared management of the water resource. – The watercourse of the Basento river, in the segment that runs through the regional capital of Basilicata, Potenza, has undertaken enhancement and redevelopment initiatives, in order to allow its reintegration into the urban fabric. The pourpose of this contribution is to outline the process that is leading to the requalification of the river area – in the context of the Basento River Park – as well as the ex Cip-Zoo, a former industrial area. The aim is to return them to the community, which is attempting to participate in decision-making processes through voluntary and spontane-ous actions. A qualitative analysis, based on questionnaires addressed to citizens, reveals that the community is searching for a space of agency, hence the demand of governance tools that can make these participatory processes more structured and effective.

Territorial education through the rivers. The “Flowing with the rivers” public engagement project. – The contribution reflects on how the value of water resources in the ecological transition can be shared and strengthened through geo-graphical education. In particular, the Public Engagement project “Flow-ing with the rivers”, financed with 48,500 euros by the University of Turin, whose objective was the development of an educational model to sustainably reconstruct the relationships between human communities and territory around water as a resource and fundamental element in all relationships between natural and human systems. The project activities developed between 2021 and 2023, concentrating the action on the territory between Turin and Savigliano, in particular between the Po, Tanaro and Maira rivers, and involved universities, associations, schools with teachers, students and parents, citizens, media and local administrations. The involvement of local communities was considered a basis of geographical education, starting from the idea that through awareness of the ecological, cultural and economic value of rivers it is possible to arrive at a plan for life, care and sustainable development that produces a social and cultural change in the valorization and management of water resources. The interdisciplinary working group, scientifically directed by Cristiano Giorda, involved fifteen researchers from six different departments and scientific areas. The main methodology followed was that of territorial education through outdoor education and place and art based learning activities, ca-pable of territorialising the scientific and artistic dimensions with skills linked to territorial values, landscape, sustainable development -bile and active citizenship.

Rationalities and socio-spatial effects of hydraulic infrastructure in Sardinia. – The infrastructural processes of the water system unfold over extended periods, often resulting in nonlinearities within the processes themselves, despite originating as explicit projects aimed at material control over resources and territorial development. These constructions give rise to various interpretations of irrigation systems, intersectoral conflicts, and power struggles among the different actors involved in their management and use. The aim of this article is to engage in dialogue regarding the water infrastructure process in Sardinia, examining its intersection with the different rationales guiding water management and territorial development policies. It highlights both internal and external factors influencing these processes, as well as the significance of historical legacies.

Artificial Intelligence for Sustainable Water Resources Management. Case Study: Gorgovivo, Ancona. – The urgent need to address challenges related to the sustainable management of water resources has prompted the scientific and technological community to explore innovative solutions that can make a significant contribution to achieving the goals and sustainability strategies of the UN’s 2030 Agenda. In this context, Artificial Intelligence (AI) emerges as a powerful ally, offering advanced tools for the collection, analysis, and management of water data efficiently and effectively. Using machine learning algorithms and neural networks, AI enables accurate prediction of water demand, facilitating optimal planning and allocation of resources. Moreover, the integration of smart sensors and monitoring systems allows real-time control of water resources, improving the response capacity to environmental variations and emergencies.
The purpose of the research is to examine how AI can optimize water treatment and distribution processes, reducing waste and enhancing the energy efficiency of water facilities; the use of predictive models based on historical data and environmental variables allows for proactive management of resources, thus contributing to their conservation and long-term sustainability. In this perspective, an AI-based system will be adopted to predict the groundwater levels of the Gorgovivo spring (AN), using historical data from the spring itself, the level of the Esino river, and rainfall stations. The proposed AI model is based on the Prophet predictive algorithm, specifically designed to manage time series forecasting applications; as adapted by us, the predictive model was evaluated using the mean absolute error (MAE), mean squared error (MSE), and correlation criteria.

Hydric resources as patterns for a community regeneration: the Gleno dam between memory and innovation in Scalve Valley. – Geography offers tools for territorial analysis and planning which, by integrating field research with geographic information technologies, propose innovative approaches to support re-generation processes. This is strategic in mountain contexts where, over time, water resources management has been at the core of a delicate co-evolutionary relationship between humans and non-humans and, sometimes, has caused catastrophic fractures induced by anthropic action, like dam collapsing. The essay presents the case study of the Gleno Dam in the Scalve Valley, province of Bergamo, where, since the collapse centenary (1923-2023), the geographers of the Imago Mundi Lab at the University of Bergamo have been carrying out research aimed at reconstructing the territorial stratification generated over time, focusing on the role of water and the disastrous results of the dam collapse on the entire valley. Many places abandoned after the disaster can today be regenerated through co-design processes using mapping systems and placing water at the centre of new symbolic meanings, cultural functions, and production practices.

A research-action path for the participatory and collaborative management of water bodies: River Contracts in Friuli Venezia Giulia. – Starting from the experience acquired through a research-action which involves the geographers of the University of Udine in the coordination of the Regional Board of River Contracts, in agreement with the Autonomous Region Friuli Venezia Giulia, this contribution analyzes the results and effectiveness of some initiatives implemented for the promotion of participatory and collaborative governance of water bodies. Through participant observation and the analysis of a questionnaire, the facilitation and training role of geography in the process of River Contracts to make participation more effective and aware, will be highlighted.

Agreements on the use of water, cooperation, policies and conflicts: river contracts in Italy. – The paper aims to explore the concept of river contract as a tool for participatory management of water resources, analyzing in this context the key role of conservation and management of their naturalness. The main objective of the research is to understand how river contracting can facilitate the conservation, enhancement and transmission of cultural heritage while promoting the sustainable development of local communities. The methodology is based on a review of the available literature on the river contract concept, its role in cultural heritage enhancement, and the need for the geo-mediation phase as an important moment of shared and participatory planning. The results of the research, in addition to highlighting regional differences in the application of River Contracts in Italy, indicate that the river contract although not widespread can act as a catalyst for the management and enhancement of cultural heritage, actively involving local communities in the conservation of their territories. The implications of the research may be useful for scholars, practitioners and institutions interested in the conservation and enhancement of water resources through the implementation of planning strategies by identifying the figure of the geomediator as a facilitator of performative processes.

Geospatial methodologies for the monitoring of eutrophication of water bodies. – As collective awareness of environmental issues increases, the debate on water pollution becomes more focused on all anthropogenic activities (industrial, agricultural and domestic discharges, waste management) that cause water eutrophication. This paper aims to highlight how the use of GIS makes it possible to examine soil erosion and to calculate the theoretical load re-located over time in watersheds by human activities. The USLE/RUSLE and CREAMS models, coupled with satellitary data, allow to examine the evolution of land and watersheds. In the first part of the paper, the focus was on the Mediterranean, one of the most polluted seas on the planet; in the second part, the watersheds of the Rio Santa Lucia, Rio San Girolamo and other minor ones in south-western Sardinia were investigated. The research highlighted the connection between spatial planning and environmental processes, underlining the importance of best practices of territory management, especially in contexts with water vulnerability. The objective is to set up an integrated methodology to monitor soil erosion and eutrophication of water resources, in order to identify strategies and actions to mitigate these phenomena.

Community Readiness for Local Covid-19 Management. – In these days, we are learning important lessons in citizen science. Today, local administrations must equip themselves with the management of infrastructures (unimaginable before Covid-19) for enforcing social distance and tracking positive cases. One of the tasks that geographers are expected to take up is the determination of the levels of societal readiness, the levels of integration in society of new technologies, products and services. The pandemic requires policies of social and cultural innovation that make communities ready to respond to catastrophic events on their territory through access to data, communities of practice, co-creation, reflection and inclusion. Finally, Covid-19 ought not to undermine the work done so far to achieve Sustainable Development Goal 1 (Poverty), 3 (Health), 4 (Education), 5 (Gender), 6 (Water), 8 (Work), 10 (Inequalities) and 16 (Peace). Pope Francis has made it clear: «This is the moment to see the poor».
