How can I estimate the hydrogeological risk of my site?
Hydrogeological risk is expressed on a scale of 1 to 5, where 1 indicates low risk and 5 represents extreme risk. This index is calculated by analyzing the intensity and frequency of events in the watershed since 1985.
Do you know the level of hydrogeological risk of your company is exposed to?
In the “Physical Hazards” section you can find an indicator that shows how exposed an area is to flooding. For each of the world’s river basins (HydroBASINS database) XNatura counts all events recorded since 1985 (source Global Active Archive and Dartmouth Flood Observatory), estimates their severity, and calculates the average probability that they will recur in the next few years.The result, adjusted with IPCC climate scenarios, is transformed into 5 hazard classes:
A full-color GIS map immediately shows you the most critical points.Why it is useful. City planners, farmers, and infrastructure designers can see where a construction site is at risk of going under water, decide if extra levees or drainage are needed, and reduce costs and environmental impacts even before work begins. Follow us to discover more KPIs and improve your risk management strategy.
How is the hydro-geological risk scale defined and calculated?
Using data on floods that have occurred in past years from 1985 to the present, collected by the Global Active Archive of Large Flood Events, it is possible to associate a flood risk with each hydrologic basin worldwide.The database of hydrologic basins is freely provided by HydroBASINS and includes 12 hierarchical levels of basins, from the most detailed (level 12, minor watershed) to the most generic (level 1, continents).Flood risk is calculated by counting the number of flood events that have occurred in the past for each basin in level 12, weighted from 1 to 3 depending on the level of severity of damage to structures and people. This indicator, with a value from zero to infinity, is then divided into 5 risk classes, from lowest to highest depending on its value.
What are the natural events related to hydrogeological risk?
Natural events related to hydrogeological risk are due to floods, including:
These phenomena can be triggered or exacerbated by heavy rainfall, prolonged droughts, loss of vegetation, and anthropogenic activities. Climate change is increasing the frequency and intensity of these events, making continuous land monitoring necessary.The XNatura platform enables monitoring of sites exposed to hydrogeological risk through geospatial data, satellite imagery and environmental sensors, supporting predictive analysis and effective adaptation strategies.
How do land use changes in the surrounding area affect the risk of my site?
Land use changes around a farm site can amplify hydrological risk in three key ways:
By constantly monitoring land use with XNatura, the company can predict these dynamics and intervene with drainage works, vegetated buffer strips or nature-based solutions, reducing overall risk and protecting assets, people and the supply chain.

Through our collaboration with XNatura, we have deployed technological solutions to foster respect for nature and the ecosystem, creating sustainable value for future generations.
The issue of biodiversity has always been central to the strategies of Mutti, whose business revolves entirely around a product of the earth, a symbol of Made in Italy in the world: the tomato. Precisely for this reason, within our Green Strategy, we have initiated a program of ecosystem restoration and rehabilitation, which starts from the very land where we have our production facilities. The collaboration with XNatura is therefore essential for us, in order to give scientific validation to our projects and help us in building a long-term strategy that will help us grow and bring increasing value to the environment.
