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.
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.
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.
