Northern Italy has been hit through a sequence of devastating floods lately. In March 2025 and the former autumn, heavy rainfall hammered the area, swamping fields, farms and cities. Greater than 3,000 needed to go away their houses in Emilia-Romagna, between Bologna and Ravenna.
The downpours led to standard floods, landslides, and infrastructure harm. This has been a repeated match since 2023 when the realm noticed what has been referred to as the worst flood in a century.
Whilst local weather alternate is a significant factor at the back of the possibility of those failures, human forget has worsened the danger. Many years of deficient upkeep of drainage canals and getting older riverbanks – a few of that are medieval, like the ones in Bologna – have made the Po valley specifically prone.
Because the meteorologist James Parrish has defined, when dried-out soil abruptly receives part a 12 months’s rainfall in two days, even fashionable flood defences can’t cope, particularly in a panorama vulnerable to waterlogging.
In line with the Italian Institute for Environmental Coverage and Analysis and the knowledge accrued in 2021 through the Nationwide Institute of Statistics, in Emilia-Romagna by myself, over 2.5 million are living in spaces of excessive or medium flood-risk.
But if lately’s floods really feel apocalyptic, historical past tells us that dwelling with floods is not anything new in those territories. Medieval communities confronted identical demanding situations and the way they lived with water might be offering courses for lately.
Because the earliest instances, other people within the Po valley advanced what the historian Petra van Dam calls an amphibious tradition: a lifestyle that incessantly adjusted to the threats and advantages posed through rivers. From the Terramare and Etruscan cultures in the second one and primary millennium BC (however even previous) to the center ages and in some circumstances even now, communities didn’t simply struggle floods; they built-in them into their day by day lives and economies.
After the autumn of the Roman state, Italy entered a duration of intense political, socio-economic, climatic and environmental alternate. As archaeological and ancient analysis displays, settlements from this era steadily clustered close to waterways regardless of their dangers.

Yearly, rivers overflowed destroying plants or structures. Proof of those occasions comes from recent narratives, such because the lifetime of Saint Fredianus, and within the flood layers buried within the soil. Strains are even present in cave minerals within the Apuan Alps.
Why are living so on the subject of one thing so harmful? As a result of rivers additionally introduced large advantages like fertile land, irrigation, generators, fish, woodlands and business.
Communities tailored in sensible tactics. They grew plants suited for rainy soils, grazed animals in seasonal marshes, or even breached riverbanks on function to let in muddy water that deposited wealthy sediment for farming. To stick dry, in addition they constructed properties on herbal or synthetic excessive grounds above floodwaters.
Those methods display a deep resilience in medieval societies, one thing to bear in mind additionally within the present state of affairs.
A shared accountability
In early medieval Italy, other people dug canals and tired wetlands no longer simply to farm new land, but in addition to control flooding and redirect rivers. Those tasks have been steadily led through monasteries, landowners, and farmers, who labored in combination out of necessity.
Analysis analysis from the Maremma wetlands in Tuscany displays how communities and rulers cooperated to deal with dikes, drainage channels, and salt pans (the place seawater used to be left to dry and go away at the back of salt). Native technology and labour mattered up to political coordination and funding.
Lately, other people steadily be expecting the state to control floods. However public reaction isn’t at all times fast or truthful. As an example, in Traversara, a village seriously hit through floods, locals have been livid in opposition to proposed obligatory insurance coverage insurance policies, feeling deserted through government.

Fashionable flood defence is based closely on centralised techniques, satellite tv for pc tracking and main infrastructure tasks. Those gear are an important, however no longer sufficient.
Ancient courses counsel that efficient flood resilience should additionally incorporate native (ancient) wisdom and group participation. Some answers come with restoring areas for rivers to overflow safely and steady centered upkeep of canals and levees.
Strengthening and adapting Italy’s consorzi di donifica – native organisations chargeable for drainage and water control – may just revive a type of shared governance that proved a success for hundreds of years.
As lately recommended within the reaction methods to the 2023 floods, responsive resilience takes teamwork. Nationwide, regional, and native actors should coordinate. On this case, adopting an “amphibious” mentality – one who perspectives rivers no longer simply as threats however as central, dwelling parts of the panorama – may just assist reshape flood coverage.
Combining ancient figuring out with fashionable science and group empowerment can information higher tactics to are living with water. Medieval societies, thru trial and adaptation, controlled to coexist with their rivers. Relearning from them lately may just assist construct extra sustainable futures in flood-prone areas – no longer best in Italy, however around the globe.
